Microwave Covers Buying Guide 2021: 10 Best Picks Reviewed

Best Microwave Covers

When reheating or cooking food in a microwave, it is not uncommon to hear popping sounds, especially if the food has fat.

Just like grills, microwaves make food sizzle, which can cause it to splatter and cause a big mess inside.

It is more hygienic to cover the food, which would also prevent excessive loss of moisture. With that in mind, these are the best microwave covers to use for the job. Read through and take your pick!

5 Things To Check Before Buying Microwave Covers

1) Functions

Although the main purpose of a microwave cover is to prevent messiness and excessive moisture loss, the product might have other functions.

Some double up as baking bowls, while others can be used as strainers/colanders.

It is obvious that multi-purpose covers have an edge over the rest, and we highly recommend them.

2) Dimensions

When it comes to dimensions, the general rule is that the larger the cover, the better.

Here you need to check the diameter and depth, which should match the standard plate size.

Ideally, any diameter above 9 inches is good, but 10 inches and above is best. On depth, the best size is at least 2 inches.

That said, the cover must fit in your microwave and therefore, you should consider this first. Measure the inner dimensions, then get a fitting size.

3) Design

There are multiple microwave cover designs. Some are transparent to give you a clear picture of what is happening inside without lifting the lid.

On the other hand, there are brightly colored options that look really good. Pick as per your personal preference.

You should also look at other design factors like steam vents to reduce moisture inside & promote even heating, and handles.

Some covers have side handles that require you to hold them using two hands, while others feature a top handle for single-hand lifting. The latter is easier to use.

For space-saving purposes, you should consider collapsible covers, such as Tovolo’s 81-31531. It is worth mentioning that those with magnetized tops also help to save on storage space because they hang inside the microwave.

You should consider them if your microwave has a flat, metal inner top that can be magnetized.

4) Material

This is an important factor to consider as the material determines how you can use the cover. Plastic units are generally cheaper, lighter, and don’t break easily.

However, they cannot withstand high temperatures, so you cannot use them when grilling.

On the other hand, glass can withstand very high temperatures. Covers like Catamount’s CECOMINOD077486 are ovenproof and flameproof.

However, they should be handled with care as they are very fragile.

With silicone, the main advantage you get is flexibility. That said, whichever material you pick, ensure it is a BPA-free microwave cover.

5) Heat Resistance

If you like using your microwave to grill, then you need a cover with high heat resistance. Glass units have the highest heat resistance and most can be used in the oven too.

As stated earlier, Catamount’s CECOMINOD077486 is ovenproof and flameproof, making it the perfect candidate for grilling.

Otherwise, a plastic or silicone cover will do.

10 Best Microwave Covers in 2021

Alright, let’s take a look at the best microwave covers that you can buy right now:

1. Best Overall: Zfitei Microwave Plate Cover

Zfitei Microwave Plate Cover
  • Dimensions: 11.5 x 11.5 x 3.34 in.
  • Material: Polypropylene

This piece is the best microwave dish cover due to its magnetized top, steam vents, easy-grip handles, and heat-focusing design.

With 4 strong magnets at the top, the cover sticks to the upper inside section of your microwave after use. This helps to save on space as no storage space is required in your kitchen.

When in use, steam vents help to reduce the moisture build-up inside. You also get easy-grip handles and since the cover is made using polypropylene, these won’t get hot.

Another benefit you get is a heat focusing design, whereby the cover concentrates heat from the microwaves for faster cooking/reheating.

That said, the unit measures 11.5 x 11.5 x 3.34 inches and will fit over almost any plate, platter or bowl. However, it cannot be used for more than 10 minutes at once, or in grill/convection mode. This is because it cannot withstand temperatures higher than 300ºF.

Note: For the magnets to work, the magnet needs to have a flat, metal top inside that can be magnetized.


  • Magnetized top for space-saving storage
  • Multiple steam vents
  • Easy-grip handles
  • Heat-focusing design
  • Fits over almost any bowl, plate, or platter


  • Cannot be used for more than 10 minutes

  • Material: Plastic

As the best budget microwave cover, this product gives you 2 pieces at a very reasonable price. Both are BPA & melamine-free, and top-rack dishwasher-safe for easy cleaning.

The pieces feature vents in the lids to prevent steam buildup when reheating. That said, each one measures 10.5 inches wide, with an internal diameter of 9.375 inches and 2-inch height. These dimensions will fit over standard dinner plates and the Nordic Ware 2-sided bacon-meat grill.

While protecting against splattering, the covers can also be used to keep food warm after cooking. On the downside, the units are not suitable for oven/grill mode because the high temperatures will melt the plastic.


  • Reasonably priced
  • 2-piece set
  • BPA & melamine-free
  • Top-rack dishwasher-safe
  • Steam vents


  • Not suitable for high-temperature use

3. Best Collapsible: Tovolo 81-31531

Tovolo 81-31531
  • Dimensions: 10.5 x 10.5 x 3 in.
  • Material: Silicone, Plastic

Tovolo’s 81-31531 is the best collapsible microwave cover because it folds from a height of 3 inches to just 0.75 inches. This makes it easy to store after use.

The folding part is made using silicone, while the black hardtop and base are built using plastic. Both materials are BPA-free, heat-resistant, and dishwasher-safe.

Finger grips at the top make it easy to grab the lid, and these are ergonomically designed to fit easily in most hands. What’s more, it does not stick out, which helps to maintain a low profile.

You also get vented holes to release all the excess moisture. When flipped, the cover can be used as a colander to strain foods using the vents.

However, just like other plastic covers, this one can easily melt under high temperatures. Therefore, don’t use it for a long time continuously.

  • Ergonomic low-profile handle
  • Vented holes

Additionally, it is non-porous and this eliminates the probability of having BPAs leaching into your food.

A safe and easy-grip silicone handle is fitted at the top for easy holding when inside the microwave.

The unit measures 10 inches in diameter, and can easily fit over 11-inch plates. It is also dishwasher-safe for easy cleaning, but there are no vent holes to release the excess moisture.

On top of that, the cover is completely food-safe as the materials are BPA, chemical & toxic-free, and won’t absorb any odors.

That said, the lid is not entirely built using silicone. It is a combination of silicone and glass. The clear glass section is placed on the upper part to enable you to monitor the status of the food at a glance without lifting the lid.

If you have to lift it, there is a heat-resistant silicone handle at the top to keep you from burning your hands.

You also get a 2-hole vent system, but the cover is very costly. It is worth the money though.

Each one has a resealable steam vent that you can open to release steam when reheating, or close to keep food warm after cooking.

The pieces are transparent and this helps you to keep an eye on your food as it cooks or reheats. If you have to raise it from the plate, there is a low-profile handle at the top to give you a firm hold of the lid.

That said, you get a 5-piece set of multicolored covers in different diameter sizes. They range from 4 – 12 inches and will fit over almost any dish.

The units are heat-resistant as they can withstand lows of -40ºF to highs of 500ºF. Within this temperature range, the pieces are completely food safe and are US food-grade approved (BPA-free).

However, since they are flat, the covers are not deep enough to be used as plates. They are suitable for bowls, pans, pots, and dishes with high walls.

Other than that, the unit features scientifically designed steam vents that ensure the food heats up evenly, while the clear color enables you to see how the food is cooking inside.

The product comes as a set of 2 pieces, all with an 11.8-inch diameter that fits over most plates, bowls, and platters.

That said, the material is tough borosilicate glass, which is oven-safe up to 450ºF, dishwasher-safe, and less toxic than plastic. It does not absorb bacteria or odor like plastic or silicone.

You can use the cover as a 2-qt baking dish because the flat top would form a stable base when inverted.

On the downside, the material is very delicate and needs to be handled with care. Also, the unit is not designed to cover bowls.

Apart from being a microwave cover, Ouchan’s piece doubles up as a strainer to drain water out of the fruits or veggies that you are washing. It uses the steam vents for this. These holes help to release excess moisture when heating your food.

The unit is heat resistant up to 300ºF and measures 10.5 inches wide. This is enough to cover most standard plates. It is also BPA-free and dishwasher-safe for easy cleaning.

Another advantage is its collapsible design for compact storage after use. However, the unit is difficult to hold using its handle. Some customers complain about this feature.


  • Doubles up as a strainer

  • Difficult to hold


1. Is It Safe to Microwave Food Without Cover?

It is completely safe but can result in splattering or loss of moisture. As such, you should invest in a microwave cover if you want to lock in moisture/taste in your food and to avoid wasting time cleaning up the mess inside after reheating.

2. Are Plastic Microwave Covers Safe?

They are only safe if they have the label/description “BPA-free and food-safe” with certifications from reliable organizations (like the FDA) to support this claim. Generally, non-plastic microwave covers are safer, but whichever you buy, ensure it is non-toxic.

3. Are Microwave Covers Dishwasher Safe?

This depends on the product. Some are dishwasher-safe, while others require handwashing. Be sure to check the manufacturer’s instructions on this.


To wrap it up, the best microwave cover overall spot goes to Zfitei’s lid due to its magnetized top for convenient storage inside the microwave after use. On top of that, it features multiple steam vents and a heat-focusing design that quickens the cooking/reheating process.

However, if you prefer a glass cover, Catamount’s lid is the best option due to its tough borosilicate glass construction. Additionally, it is flameproof and ovenproof.

We also highly recommend silicone covers like Bezrat’s 8541989017 for the job. The lid is oven-safe up to 450ºF and completely food-safe. What’s more, it has a glass upper section for peeking at the cooking inside.
