Microwaving food is a daily convenience for many. However, splatters, uneven heating, and moisture loss can plague this quick cooking method. Properly covering your food while microwaving is crucial for preventing these issues. But what are the safe and effective options available? This article delves into the various materials you can use to cover food in the microwave, exploring their benefits, drawbacks, and safety considerations.
Understanding the Importance of Covering Food in the Microwave
Covering food in the microwave isn’t just about preventing a messy clean-up. It plays a vital role in how your food cooks and tastes.
Think about those frustrating microwave explosions. Sauces erupt, liquids splatter, and suddenly your microwave looks like a Jackson Pollock painting. Covering your food significantly reduces this mess. It creates a barrier that traps splatters and keeps your microwave cleaner.
Beyond cleanliness, covering your food ensures more even heating. Microwaves work by exciting water molecules within the food. Covering the dish traps steam, which helps to distribute the heat more evenly throughout the food. This prevents some parts of your meal from being scorching hot while others remain cold.
Furthermore, covering helps retain moisture. Microwaving can dry out food, leaving it tough and unappetizing. By trapping steam, you keep your food moist and prevent it from becoming rubbery or hard. Retaining moisture is especially important for foods like leftovers, vegetables, and casseroles.
Microwave-Safe Covers: Your Best Options
Several materials are specifically designed for microwave use. These options offer a balance of safety, effectiveness, and convenience.
Microwave-Safe Plastic Covers
These covers are usually made from polypropylene or other microwave-safe plastics. They come in various shapes and sizes, from simple lids to vented domes.
One major advantage of plastic covers is their reusability. You can wash and reuse them countless times, making them an economical and environmentally friendly choice. They are also lightweight and easy to store. Look for plastics labeled as “microwave-safe” or with the recycling symbol #5.
However, not all plastics are created equal. Avoid using containers or covers that are not explicitly labeled as microwave-safe. Some plastics can leach chemicals into your food when heated, which is a health concern. Also, be mindful of scratches or damage, as these can compromise the integrity of the plastic and increase the risk of chemical leaching.
Silicone Covers and Lids
Silicone is a synthetic rubber that is becoming increasingly popular for kitchenware. It’s known for its heat resistance, flexibility, and non-stick properties.
Silicone covers are a fantastic alternative to plastic. They are generally considered safer than plastic because they are less likely to leach chemicals into food when heated. High-quality silicone is BPA-free and phthalate-free. They are also very durable and can withstand high temperatures.
Another benefit of silicone covers is their versatility. They can often be used in the microwave, oven (up to a certain temperature), and freezer. Many silicone covers are designed to create a tight seal, further enhancing their ability to retain moisture and prevent splatters.
While silicone covers are generally more expensive than plastic covers, their durability and safety make them a worthwhile investment.
Glass Turntable Covers
These covers are designed to sit directly on the turntable inside your microwave. They are typically made from tempered glass, which is heat-resistant and shatter-resistant.
Glass turntable covers are an excellent option for even heating. Because glass is a good conductor of heat, it helps to distribute the microwaves more evenly around the food. This minimizes hot spots and ensures that your food cooks thoroughly.
These covers are also very easy to clean. You can simply wipe them down with a damp cloth or put them in the dishwasher. Glass is also non-porous, meaning it won’t absorb odors or flavors from your food.
One potential drawback of glass turntable covers is their fragility. While tempered glass is more durable than regular glass, it can still break if dropped or subjected to sudden temperature changes. They also tend to be more expensive than plastic or silicone covers.
Household Items That Can Be Used as Microwave Covers (With Caution)
Sometimes, you might not have a dedicated microwave cover on hand. In those situations, you can use certain household items as a temporary solution, but with careful consideration.
Microwave-Safe Plates and Bowls
Using another microwave-safe plate or bowl as a cover is a common practice. This works well for preventing splatters and trapping steam.
Ensure that the plate or bowl you use is explicitly labeled as microwave-safe. Materials like stoneware, porcelain, and some types of ceramic are often microwave-safe, but it’s always best to check the manufacturer’s instructions.
Avoid using dishes with metallic trim or accents, as these can cause sparks and damage your microwave. Also, be careful when removing the cover, as it can become very hot from the trapped steam.
Paper Towels
Paper towels are a readily available option for covering food in the microwave. They are particularly useful for preventing splatters when reheating liquids or greasy foods.
Paper towels are porous, which allows some steam to escape. This can be beneficial for preventing condensation buildup, which can make food soggy.
However, it’s crucial to use plain, unprinted paper towels. Avoid using paper towels with dyes or patterns, as these can leach chemicals into your food when heated. Also, ensure that the paper towel doesn’t touch the food directly, especially if the food is high in fat.
While paper towels are convenient, they are a single-use item and therefore not the most environmentally friendly option.
Parchment Paper
Parchment paper is another safe and versatile option for covering food in the microwave. It’s heat-resistant, non-stick, and won’t leach chemicals into your food.
Parchment paper is especially useful for covering delicate foods like fish or vegetables. It helps to retain moisture and prevent them from drying out.
Like paper towels, parchment paper allows some steam to escape, preventing sogginess. However, it’s also more effective at trapping heat than paper towels.
Materials to NEVER Use in the Microwave
Certain materials are strictly prohibited from being used in the microwave due to safety concerns. Using these materials can damage your microwave, cause a fire, or contaminate your food.
Metal
Metal is a big no-no in the microwave. Metal reflects microwaves, which can cause sparks, arcing, and even fires. Never use aluminum foil, metal containers, or dishes with metallic trim in the microwave.
Even small amounts of metal, such as a twist tie or a metal spoon, can cause problems. The reflected microwaves can also damage the magnetron, the component that generates the microwaves.
Plastic Wrap Not Labeled “Microwave-Safe”
While some plastic wraps are designed for microwave use, not all are created equal. Using plastic wrap that is not labeled as microwave-safe can be dangerous.
Non-microwave-safe plastic wrap can melt, warp, or release harmful chemicals into your food. Always look for plastic wrap that is specifically labeled “microwave-safe” or “suitable for microwave use.”
Even with microwave-safe plastic wrap, it’s best to avoid direct contact with the food, especially if the food is high in fat. The heat can cause the plastic wrap to melt and stick to the food.
Foam Containers (Styrofoam)
Foam containers, often used for takeout food, are not microwave-safe. They can melt, warp, and release harmful chemicals into your food when heated.
Styrofoam is particularly problematic because it’s made from polystyrene, a known carcinogen. Heating polystyrene can cause it to leach into your food, posing a health risk.
Always transfer food from foam containers to a microwave-safe dish before reheating.
Paper Bags
Paper bags, especially those used for groceries or takeout, are not suitable for microwave use. They can catch fire or release harmful chemicals into your food.
Paper bags are not designed to withstand the high temperatures of a microwave. They can easily ignite, creating a fire hazard.
Anything with Metallic Decoration
As a general rule, anything containing metal should be kept out of the microwave. This includes plates, bowls, or other dishes with metallic decorations, such as gold or silver trim.
Even small amounts of metal can cause sparks and damage your microwave. It’s always best to err on the side of caution and avoid using anything with metallic decoration in the microwave.
Tips for Covering Food Effectively in the Microwave
Beyond choosing the right materials, there are some simple techniques to maximize the benefits of covering your food in the microwave.
Leave a vent. Whether you’re using a plastic cover, silicone lid, or parchment paper, it’s essential to leave a small vent to allow steam to escape. This prevents pressure from building up inside the container, which can cause splatters or even explosions. You can leave a corner of the cover slightly ajar or pierce a few holes in the parchment paper.
Avoid Overcrowding. Don’t try to cram too much food into the microwave at once. Overcrowding can prevent even heating and increase the risk of splatters. If you’re reheating a large portion of food, it’s best to do it in smaller batches.
Rotate and Stir. Even with a cover, it’s a good idea to rotate and stir your food halfway through the cooking time. This helps to distribute the heat more evenly and prevents some parts of the food from becoming overcooked while others remain cold.
Check for Hot Spots. After microwaving, be careful when removing the cover, as the steam can be very hot. Use oven mitts or pot holders to protect your hands. Let the food stand for a minute or two before serving to allow the heat to distribute evenly.
Clean Regularly. A clean microwave is a safe microwave. Regularly wipe down the interior of your microwave to remove any food splatters or spills. This will prevent odors from building up and reduce the risk of fire.
Making the Right Choice for Your Needs
Choosing the right material to cover your food in the microwave depends on your individual needs and preferences. Consider factors like safety, convenience, cost, and environmental impact when making your decision. Microwave-safe plastic covers and silicone lids offer a good balance of safety, reusability, and convenience. Glass turntable covers are excellent for even heating. Paper towels and parchment paper can be used as temporary solutions, but with caution. Always avoid using metal, non-microwave-safe plastic wrap, foam containers, paper bags, or anything with metallic decoration in the microwave. By following these guidelines, you can ensure safe, effective, and mess-free microwaving every time.
Can I use plastic wrap to cover food in the microwave?
Plastic wrap can be used to cover food in the microwave, but it’s crucial to choose the right type. Look for plastic wrap specifically labeled as microwave-safe. This designation means it’s made of materials that won’t melt or leach harmful chemicals into your food when heated.
However, even microwave-safe plastic wrap should not come into direct contact with the food. Leave some space between the wrap and the food surface to prevent melting and potential contamination. Vent the wrap slightly to allow steam to escape and prevent pressure buildup.
Is it safe to use paper towels to cover food in the microwave?
Yes, paper towels are generally safe to use for covering food in the microwave, particularly for absorbing splatters and keeping the microwave clean. They’re especially useful for foods like bacon or items prone to popping and making a mess. Opt for plain, white paper towels without any printed designs, as the inks could potentially leach into the food.
Avoid using recycled paper towels, as they may contain metal fragments that can spark in the microwave. Also, never use paper towels to cover food being microwaved for extended periods, especially if it contains high amounts of fat, as they could potentially catch fire. Always monitor the microwave while it’s running.
Can I use aluminum foil in the microwave to cover food?
No, it is generally not safe to use aluminum foil to cover food in the microwave. Aluminum foil is a metal, and microwaves interact with metal in a way that can cause arcing, sparks, and potentially even a fire. The microwaves are reflected off the foil instead of being absorbed by the food, leading to uneven heating.
Although small amounts of foil might be acceptable in some instances (like covering the ends of poultry to prevent over-browning), covering the entire dish is strongly discouraged. The risks of fire and damage to your microwave outweigh any potential benefits. Always choose alternative covering methods for microwaving.
Are microwave-safe lids a good option for covering food?
Yes, microwave-safe lids are an excellent and reusable option for covering food in the microwave. They help to trap steam, ensuring more even heating and preventing splatters. These lids come in various sizes and materials, including plastic and silicone, so choose one that fits your dishes well.
When selecting a microwave-safe lid, ensure it is specifically labeled as such. Look for lids that are BPA-free and heat-resistant. Also, consider lids with vent holes or adjustable vents to allow steam to escape and prevent pressure build-up, which can lead to messy explosions.
Can I use glass containers or lids to cover food in the microwave?
Using glass containers and lids in the microwave depends on the type of glass. Tempered glass, specifically labeled as microwave-safe, is generally safe to use for covering food. However, regular glass, especially thin or delicate glassware, can shatter due to the rapid temperature changes.
Always check the manufacturer’s instructions to confirm that your glass container or lid is microwave-safe. Avoid using glass that is chipped, cracked, or has decorative metallic accents, as these can cause arcing. If in doubt, opt for specifically designed microwave-safe glass containers.
Is it safe to use ceramic plates or bowls to cover food in the microwave?
Similar to glass, the safety of using ceramic plates or bowls to cover food in the microwave depends on the specific type of ceramic. Ceramics labeled as microwave-safe are generally acceptable. However, it’s crucial to check for any metallic decorations, such as gold or silver trim, as these can cause sparking and potential damage to your microwave.
Avoid using cracked or chipped ceramic dishes, as the heat can cause them to break further. Some ceramic glazes also contain lead, so it’s best to use pieces that are specifically designed for microwave use and have been tested for lead content to ensure safe food preparation.
What about using reusable silicone covers for microwaving?
Reusable silicone covers are a safe and convenient option for covering food in the microwave. Silicone is heat-resistant, non-toxic, and doesn’t leach chemicals into food when heated. These covers create a tight seal, helping to trap steam and ensure even heating, while also preventing splatters.
Look for silicone covers that are specifically labeled as microwave-safe and BPA-free. Ensure they have small vent holes to allow steam to escape and prevent pressure from building up. Silicone covers are easy to clean and are a more environmentally friendly alternative to single-use plastic wrap or paper towels.
