Meal preparation containers are among the essential elements of every kitchen. They make food preparation and storage a lot easier and simpler. Quality containers are microwave-, dishwasher- and freezer-friendly. Also, they have to be easy to pack and take to work, gym, or on a field trip.

The use of hypoallergenic and non-toxic materials is of the utmost importance when it comes to preparation and storage containers. High-quality glass and BPA-free plastics are the most desirable options, as they will keep you and your family safe.

Prep Naturals Glass Meal Containers Review

This is a set of five Prep Naturals Glass Meal Containers. These high-grade borosilicate glass containers are equipped with airtight lids with the SmartestLock sealing system. All five containers are 30 oz. in volume and can withstand temperatures of up to 840° Fahrenheit. Also, they can withstand standard freezer temperatures.

Who is this product for?

This set is excellent for families and busy individuals who cook lunch for several days in advance. With this set, you’ll be able to cook ahead for the entire work week and store the food safely in the freezer. Thanks to their robust borosilicate glass construction, you can take these containers on camping trips and to the office.

The big size (30 oz. capacity) and high temperature resistance make these containers an ideal alternative to cooking in classic pots and pans. They are also microwave-friendly and can easily be washed in a dishwasher, making them a great option for homemakers looking to reduce the kitchen clutter. Finally, they are a good option if you have to prepare different meals for your family members.

What’s included?

The package includes a set of five borosilicate glass containers. The glass is thick and strong enough to withstand high oven temperatures (above 800° Fahrenheit), as well as freezer conditions.

There are no alternative sizes, bigger or smaller, but you find other Prep Naturals sets with glass containers of different sizes. Along with the containers, you’ll also get five plastic (BPA-free) lids. Other than that, there are no accessories or extras included in this bare-bones package.

Overview of features

The containers are uniform in size – 30 oz. capacity across the board. All of them measure 4.75” (W) x 6.5” (L) x 2” (H), conveniently sized to fit an average adult hand. They are also easy to fit in a fridge or freezer. You’ll typically be able to stack up several containers on one freezer or fridge shelf.

The single-compartment design is great for cooking whole meals and storing larger quantities of a single food item. However, these might not be the best solution if you want to pack several different items into one container and store them for later, for example.

Construction-wise, the borosilicate glass is sturdy and thick. Properly made borosilicate glass is hypoallergenic and resistant to extreme temperatures. This means that you’ll be able to cook meals and freeze leftovers in them with no problem. Also, the sturdiness of borosilicate glass makes them dishwasher safe.

Without the lids, these containers fit nicely within each other, as the bottoms are slightly narrower than the tops. With the lids on, they don’t stack up as neatly. Therefore, make sure to position them well if you intend to stack them in the freezer.

The lids are made of plastic and feature thick silicone seals around the edges. The airtight lids are equipped with a vent in the middle and snap-on tabs on the edges. Unlike the containers, the lids are not oven-safe.

All materials used in the production process are BPA-free. They’ve also been approved by the FDA and LFGP.

How to get the most out of them

There are several simple things you can do to get the most out of these containers. First, make sure to take the lids off when cooking in the oven, or flip open the vent when reheating leftovers in the microwave. Also, if you intend to wash the containers in the dishwasher, make sure to take the lids off and put them on the top rack.


Though a great set, this Prep Naturals Glass Meal Containers set offers only one size – 30 oz. Also, all featured containers are rectangular in shape. If you need more versatility in terms of size or you want a mix of rounded and rectangular containers, the Pyrex Simply Store Glass Food Container Set might be a good alternative. This set comes in with 18 glass containers ranging in capacity from 1 to 7 cups.

On the other hand, if multi-compartment containers are what you’re after, you might want to take a look at this set of MCIRCO Glass Meal Prep Containers. The set includes six 36 oz. containers with three compartments each, making them perfect for bento-style meals and storing small quantities of similar foods together.


The Prep Naturals Glass Meal Containers offers large-capacity containers with airtight lids. It is a great option for cooking and storing away whole meals for several days in advance. The high-grade borosilicate glass and BPA-free plastic used, as well as the top-notch construction quality, put this set among the top glass meal prep containers options out there.
