Can you Microwave Aluminum Foil? [Tested – See Video]

can you microwave aluminum foil?It sounds like misinformation doesn’t sound factual! Myths like; “You shouldn’t use metal containers in the microwave,” or “metal does not enable microwaves to absorb the food.

Thus, any food inside the metal will remain raw.” And, “Metal can make them oven burn!”

The question remains whether can you microwave Aluminum foil

The answer is yes! You can microwave aluminum foil. However, it can be risky at times since it can easily ignite a fire once sparks or smoke from inside the microwave are formed. That said, there are several precautions to remember when using aluminum foil in the microwave.

For instance, aluminum foil can be a better choice than cardboard or plastic containers that leach dangerous chemicals into your food.

Furthermore, aluminum is more recyclable and environmentally friendly than plastic cans.

Alternatively, sharp-edged aluminum foils are more likely to generate sparks than those with flawless edges. One issue with aluminum foil is it crumbles up with a single touch. Again, higher wattage, together with aluminum foil, can lead to greater chances of something transpiring.

So, let’s uncover some safe ways to use aluminum foil and tins to cover food in the microwave.

Rules for Safe Use of Aluminum Foil in a Microwave Oven

can you microwave aluminum foil?You now understand that aluminum foil can ignite a fire under certain circumstances but can be safe to use in others. You’re probably fantasizing about how you can ensure that your microwave doesn’t accidentally explode while using your aluminum foil. To answer, here are some rules the USDA provides as safe while using foil in the microwave and other important tips.

1. Use Shallow Foil Containers Only

Microwaves have limits. They can penetrate into food but are only a couple of inches deep. The remaining part of the cooking is through conduction.

If the tray you’re using is more than three inches deep, the upper part of your food will likely heat, whereas the bottom will not. So, you’ll have to return it the second round, and by the time the heat is evenly distributed, the top is overdone and might be burning.

To prevent this, consider using shallow foil containers

2. Never cover more than 25% of the food with foil

We know that microwaves spring back from metals. If you fully wrap your food in foil, it can’t heat up. So, cover only the parts that can burn.

For example, if you’re heating meat, pin the thin sections of the foil against the thin parts using wooden toothpicks. Hence the thicker portions will warm nicely without burning or drying the inner parts.

Once you become an expert, you’ll know the amount of foil you require contingent on the dish you’re heating up.

3. The side of the foil doesn’t matter (shiny or dull) is facing out

Some people argue whether to use the shiny or dark side of the foil. Actually, the USDA declares it doesn’t matter. The variation of the two sides results due to the manufacturing procedure and doesn’t affect the effectiveness of the foil.

4. If your microwave has a metal turntable, don’t put aluminum or any metallic substance in it

Always avoid contact among two metals at any cost. Some people propose placing a different item between (like ceramic plate or glass underneath the aluminum foil tray), though USDA warns against using aluminum entirely in such a situation.

5. Read the manufacturer’s requirements for safety. They might have found a better solution

The role of the metal walls in your microwave is to reflect the microwaves and protect you against them. Place the foil in the center of the plate, ensuring it does not touch the oven walls. Basically, microwaves are dangerous to living things. But provided your oven is functioning well, there’s no need for alarm.

Suppose there happen to be some pieces of foil that touch the sides, even a little, fold and even them out immediately. They should not be rubbing on the walls when rotating as that may attract danger (like sparks).

Why you might want to microwave aluminum foil

It is easily available

If you turn your head, aluminum seems to be all over. According to the University of Wisconsin, it is among the most abundant items in the universe, occupying approximately 8% of the earth’s mass. It also occurs in plenty among pizza crusts, contributing a huge percentage of the containers that carry most frozen pizzas. They are abundant in cake pans, popcorn bags, cake pans, pie plates, and soup carton lids.

It is made from good material.

Aluminum is strong, light, and easy to shape. It can also resist corrosion and is recyclable. It is one-third the weight of copper or steel, says researchers from the U.S. Geological Survey. That makes it an all-functional item that you can design into anything you may want.

It has many uses

In food manufacturing industries, producers use foil to store food in containers and in lids to retain warmth in food. In baking, it is used to regulate heat and other places.

Since aluminum appears in the microwavable baking dish, it can help redirect heat in foo and turn it crispier. It occurs in:

  • Pie plates
  • Lasagna tins
  • Roasting pans
  • Bread loaf tins
  • Cake pans
  • Chicken pot pie pans

Microwavable items with peel-off lids usually leave a disc-shaped aluminum along the edge. Among them are containers for:

  • Stews
  • Casseroles
  • Soups
  • Instant noodles

Furthermore, you may desire to use aluminum foil to cover food sections against the microwave heat. Thus, the key area will heat without burning the sides. Best examples include:

  • Protecting the legs and wings when microwaving full turkey or chicken.
  • Shielding only the crust of a pie to prevent it from burning as you heat.
  • Covering the tips of a ham’s leg

Substitutes you Can Use Instead of Aluminum Foil

1. Wax paper

Can you Microwave aluminum foil?Wax paper is also used as a substitute for aluminum foil but is not the best potion when cooking oily foods or those that can burn easily.

2. Parchment paper

Parchment paper guarantees heat distributes evenly during heating. Different from foil, it has exceptional heat retaining properties.

3. Plastic wrap

Plastic wraps are more microwave safe, making them the best alternative. But it should never touch the food as it can create toxic elements if functioning under high temperatures.

4. Silicone Oven Liner

If you prefer lining the bottom of your microwave to trap drips and spills, you can use a silicone oven liner. Silicon liners, unlike aluminum foil, don’t replicate heat. Moreover, the liner doesn’t get caught at the bottom of the oven and is usually dishwasher friendly.

The Oven Rack

Can you Microwave Aluminum Foil?Another alternative is to use the oven rack itself. However, it can only work for various food types like pizza. That is why most people line the underside of their ovens using foil, which is something you should avoid.

Dutch oven

Instead of covering foods using foil, why not use a Dutch oven to retain the moisture? A Dutch oven is usually made from ceramic or iron and has a tight-fitting lid that evaporates moisture.

Faqs About Can You Microwave Aluminum Foil? 

What happens if you put aluminum foil in the microwave?

If your microwave has metallic walls, it doesn’t signify they are dangerous. Aluminum foil is normally light; therefore, immediately food starts to heat, the liquid changes into moisture, creating energy.

Energy cannot get out once the food is shielded with foil, hence quickening the healing process.

Can you put aluminum foil in any microwave?

You should never use aluminum foil to cover food in a conventional microwave. It will repel heat away from the container, making it cook faster but unevenly.

What happens if you microwave for three minutes?

If you happen to microwave for three minutes and forget to remove the foil immediately, you might spoil your appliance or burn your kitchen.

When using anything metallic inside the microwave, charges start to move all over. If it’s a light metal similar to aluminum foil, voltages start to form, surpassing the air voltage, thus creating a spark.

What happens when you heat aluminum foil?

It is safe to heat aluminum foil, but you should observe certain guidelines.

Can tin foil go in the oven?

Some people refer to aluminum foil as tin foil. Tinfoil is mostly used in the oven in different ways. You can use it to either maintain cleanliness in the oven or use it for cooking. Regardless of how you decide to use the tin foil, always remember that some ways are not as safe.

Which side of aluminum foil is toxic?

Aluminum foil has two sides which are the shiny and the dull sides. Even so, it doesn’t matter which side you use to shield your food as they are all acceptable.

Can tin foil catch on fire?

Tinfoil cannot catch fire, whether from the grill, oven, or in a campfire. However, it can burn, and that’s why sparklers use it for fuel. But in a sparkler, the tin foil is powdery.

Why wrap your door knobs in aluminum foil when you are alone?

Cover it using aluminum foil to prevent the door from getting grazes, drips, or splatters from paint when painting your door. Lay the foil on the door for a perfect finish, then cut off the surplus using a sharp knife around the boundaries.

Can foil go in an air fryer?

You can use aluminum foil with your air fryer, but only if it goes inside the basket. Aluminum affects acidic foods; hence never use foil to air fry peppers, tomatoes, and citrus.

You can use an empty basket or parchment paper since they are better than foil and they don’t alter the cooking process.

Is aluminum foil cancerous?

According to research, it is evident that microwaving food using aluminum foil has very minimal health risks. It does not escalate your probability of getting cancer or other harmful health conditions unless you consume it in huge quantities.

EFSA (European Food Safety Authority) and WHO (The World Health Organization) have set acceptable weekly consumption between one to two milligrams per kg of the body load.

Other news has reported that aluminum is connected to Alzheimer’s disease and other cancer varieties, but different studies have been unable to identify a solid connection.

Why should you wrap your feet in foil?

Foil is a medication for colds and flu, which may leave you immobile. Cover your feet with about five to seven coats of aluminum while inserting cotton or bandage in between. Let it rest for one hour, then remove. Repeat the process twice and note the difference.

Is it safe to store food in aluminum foil?

On the flip side, aluminum is not good for storing food especially remains. Refrigerated remains can only last for four days when the leftovers are covered and stored well. However, most people prefer shielding the plate using foil then throwing it in the fridge. That, to them, is the simplest way to store food.


Because of the many advantages that aluminum foil has in our cooking stations, it is basically one of the simplest cooking styles. Only remember that not every food is good with aluminum. However, if you want to reduce your aluminum consumption, you can look for a different option.
