Verywell Fit / Kevin Liang Meal prep containers can simplify your life and set you up for success on your meal prepping journey by making it easy to store, transport, and reheat pre-portioned meals. The best meal prep containers are made from durable and food-safe material, easy to clean, and sized to your specific needs. While meal prepping can be tedious, it's a great way to plan what you'll eat. According to Eliza Savage, MS, RD, CDN, "Investing in high-quality meal prep containers is a great way to set you up for success with your nutrition goals. Planning—and preparing—meals and snacks ahead of time makes sticking to your meal plan simple. If meal prep feels overwhelming, I suggest starting with one meal, such as breakfast. Mixing up a large batch of overnight oats and storing it in individual containers makes mornings easier." Other features to look for include compartments for different foods, lids with a secure closure system, and whether or not the container is microwave-safe, dishwasher-safe, freezer-safe, or oven-safe. We researched a variety of options with these helpful features in mind. A registered dietitian nutritionist from our Review Board reviewed this article for accuracy and safety in regard to different types of materials and how they handle temperature changes such as freezing and reheating.

The most popular materials used in food storage containers are glass, plastic, stainless steel, and silicone. Keep in mind that reusable containers are only more environmentally friendly than single-use containers if they are used many times over. Each material has its pros and cons; overall, it's a personal preference. Glass containers are a sturdy, low-maintenance option that are dishwasher- and microwave-safe and typically also freezer and oven-safe. Another major selling point is that glass is nonporous, meaning there’s no space to trap odor and bacteria. Glass is also free of potentially harmful chemicals. On the flip side, glass containers are much heavier, fragile, and can be more costly. BPA-free plastic containers are another great option to consider. In addition to being mostly dishwasher- and microwave-safe, plastic containers are lightweight and budget-friendly. High-quality, sturdy plastics wear well and won’t warp or dent in the dishwasher. Plastic is not the most eco-friendly pick of the bunch, and it’s important to note that if your plastic containers crack, they are no longer safe to use and should be disposed of properly. Be sure to choose BPA-free plastic to avoid potentially harmful chemicals. Stainless steel containers are a popular option for preparing cold meals. These eco-friendly metal containers are often offered in compact bento-style lunch boxes, packing seamlessly in a work or school bag. While stainless steel cannot be heated, it is generally dishwasher-safe. Due to its malleable nature, silicone is a smart choice for anyone looking to save space, either in the kitchen or in a lunch bag. Silicone bags are designed to replace single-use plastic bags and can usually be used for a variety of cooking methods. Capabilities The idea behind meal prepping is to make life easier and spend less time cooking and cleaning. To get the most out of your efforts, look for meal prep containers that are safe to use in the microwave, dishwasher, freezer, and oven. Compartments Compartmentalized meal prep containers are a popular choice, especially for kids or for preparing multi-course meals. Bento boxes are a great option for packing a variety of food in one compact container and keeping wet and dry foods separate. Ease of Cleaning There's nothing worse than cracking open your lunch container after a long day and spending what seems to be endless amounts of time scrubbing. The beauty of a nonporous material like glass is that it doesn't absorb odor or bacteria, making cleaning much easier. Ideally, find a container that is dishwasher-safe to cut down on cleaning time. Durability Invest in meal prep containers that will last for years and will stand up to a little roughhousing and the occasional tumble. Additionally, make sure the material is sturdy enough to handle the microwave, freezer, and dishwasher. Lid Design Look for a lid that incorporates a seal, suction, or locking mechanism. This ensures a secure hold, keeping liquids from seeping in between the cracks and spilling. Size Meal prep masters seek the ideal balance between storage space and food capacity. Since every meal and family member is different, we suggest investing in a variety of container sizes for different meals and portion sizes. Frequently Asked Questions How many containers do you need for meal prep? It depends. If you want to prepare a certain number of meals at a time to be able to simply grab a container and go, you will need to purchase one container per meal you prepare in advance. Another way to do it is to prepare different dishes ahead of time (like tofu, roasted vegetables, and rice pilaf) and store each dish in a large container. This way, you can portion out the different dishes into a serving-size meal prep container before you leave for work or onto a plate to heat up for dinner, and you only need a few containers. Take note of how long the dishes you prepare will last in the fridge to determine how far in advance to prep your meals and, therefore, how many containers you will need. What size meal prep containers should you get? “If you are planning on prepping full meals, then you will want a substantial container. Better yet, choosing a container with separate compartments can help separate each part of your meal," says Laney Morse, RDN, CPT, BCS. "If you are only looking to prep snacks or single components, then purchase containers based on the items you plan on making. Typically a 32-ounce container will fit a full meal easily, and a 12-to-16-ounce container can be used to store snacks." Are plastic meal prep containers safe? According to Morse, it depends on the brand. “Many companies are now focusing on removing harmful chemicals [from plastic containers]. On the bottom of food containers, you’ll find a number printed somewhere that will be between 1 and 7, which indicates what the plastic is made of. Plastics with numbers 1, 2, 4, and 5 are generally considered safe to be used with food. Numbers 3, 6, and 7 are generally considered unsafe or higher risk of contaminating food and should be avoided for use as storage containers.” Can you freeze meal prep containers? It depends on the material of the container. “Most heavy glass containers, such as Pyrex, and most plastic containers can be frozen for short or long periods of time without any issues. Be sure to read the details of the product prior to buying, as companies may disclose information about the increased risk of cracking or breaking of containers based on the material, however, most should have no trouble being frozen,” says Morse. Can you microwave meal prep containers? It depends on the material of the container. Look for “microwave-safe” in the product description or on their website. “Metal should never be microwaved as it is a conductor of electricity and can cause serious harm to the microwave, product, and yourself. For plastic, be sure to read the fine print of the product description or find out which type of plastic the container is made of,” says Morse.“If the company states a plastic container is microwave-safe, then it likely won’t melt or overheat; however, the type of plastic will determine if any chemicals [may leach] into your food when heated,” Morse says. Look for BPA-free containers. Glass containers are safe to microwave, but the lids are not always microwave-safe, so check the product description. How long do meal prep containers last? If you take care of your containers, they will last for many years. Morse explains further, “Glass containers are not porous and therefore will not get stained or wear out over time as long as they are properly washed, dried, and stored. However, glass is prone to breaking. Depending on the brand, thickness, and type of plastic used, plastic containers can also have a very long lifespan."Plastic is a porous material and is prone to stains and discoloration. Typically, this is harmless, but if this is off-putting to you, then glass may be a better choice. As long as plastic is washed thoroughly after each use, it should be fairly easy to prevent stains."Microwave-safe containers should not melt or lose their shape when heated. However, if this occurs, it’s probably a good idea to discard the container to prevent leaking or contamination of food if the container is no longer air-tight.” Why Trust Verywell Fit Emily Stone researches and reviews products for Verywell Fit and Verywell Health.
