Lid, material, size and shape are all factors used to determine which microwave safe containers to purchase.  So how do you decide which microwaveable containers are best for meal prep, storage and reheating food?

Well, there are a few key factors to consider when selecting microwavable containers for food. Aside from the being microwave safe, here are some important factors to think about:

  • Size: Portion control is a primary necessity in meal prep. The size needs to be adequate to nourish your needs, but not be too abundant that you end up overeating. However, sometimes its necessary to have a range of sizes to accommodate various meal prep essentials.
  • Material: Glass does not stain, absorb odors or harbor flavors. Therefore, it seems to be the best material choice in this situation. In hindsight, plastic lids don’t rust and plastic containers don’t shatter.
  • Lid: The lid must be food grade, rust-free and also needs to lock in place. Snap-on lids with airtight locking are also a benefit. Plastic lids are rust-free and are fairly durable over time.
  • Shape: Round, square or rectangular are determined by your storage space and personal preference. However, dual compartment separation is nice to keep meal prep items divided while still remaining in the same microwave safe container.

How do you know if a container is microwave safe?

In general, glass and ceramic containers are microwave safe unless otherwise noted by the manufacturer. Some specific plastic materials have been tested by the FDA and are also declared microwave safe.

Microwave safe is usually written or the microwave safe symbol (a microwave with wavy lines) is used on the bottom of a container.

It’s best to follow manufacturer recommendations when considering whether or not a container is microwave safe. If the container is plastic, then there will also be a number on the bottom associated with the type plastic compound used.

Is it safe to use plastic containers in the microwave? Plastic takeout containers, water bottles and condiment tubs or jars are usually not microwave-safe. Damaged, scratched or old containers that have been microwaved many times may also leach out chemical compounds into food or water.

Stick to manufacturer recommendations and only use containers that are labels microwave safe. However, sometimes numbers describe the chemical compound used to make the container.

When using a plastic container, check the bottom to see what type of material is used.

  • 3, 6, 7 are not microwave safe
  • 1, 2, 4 are sometimes microwave safe.
  • 5 is polypropylene, PP, and is generally considered safe to use in the microwave.

What container is best for microwave?

Glass containers are best to use in the microwave. Glass does not stain or retain odors. Furthermore, it won’t leach out potentially hazardous chemicals into your food or water. Ceramic containers also work well for similar reasoning, they do not stain and odors do not permeate into the surface.

Avoid plastics that are not labeled as microwave safe, and also do not heat Styrofoam in the microwave. Here are the best microwave safe containers that you can safely use for meal prep, storage and reheating food in the microwave.
