Between planning, shopping and cooking, you've worked hard to prep several days' worth of healthy meals. To reap the most from your efforts, it makes sense to pack up your food in high-quality containers.

The right meal prep containers will keep your food fresher for longer so that it tastes as good by the end of the week as it did when you first packed it. Quality containers will also help keep spills at bay and make it easy to see exactly what you have stocked in the fridge — both keys to minimizing food waste.

There are about a million options to choose from, though, so how can you know which ones are best?

What to Look for in a Meal Prep Container

Before you go shopping or fill your Amazon cart with containers, keep these must-haves in mind.

  • Pick containers with an airtight lid. Lids with airtight seals keep air from penetrating your food so it stays fresher longer, Andres Ayesta, RD, tells LIVESTRONG.com. And they can help prevent annoying spills when a container tips over.

  • Get a variety of sizes. A mix of big and small containers helps you max out storage space in your fridge. Use big vessels for large batches and smaller ones for portioning out individual servings that you can take for lunch or stow in the freezer.

  • Make sure plastic containers are safe to use. Plastic containers often contain endocrine-disrupting chemicals like bisphenol-A (BPA) or phthalates that can leach into food, especially when the plastic is heated or exposed to bright light. The risk of leaching is higher with hot or wet food, but it can occur with dry food too, Ayesta says. Glass containers are naturally free of endocrine-disrupting chemicals, and since they're clear, you can see exactly what's inside. If you choose to go with a plastic option, make sure it's listed as BPA-free.

Tip

The Academy of Nutrition and Dietetics recommends checking the resin identification code (RIC), located inside a triangle on the bottom of the container and only go for those labeled with numbers 1, 2, 4 and 5. August 2018 recommendations from the American Academy of Pediatrics (AAP) recommend avoiding containers with the code 3, as these contain phthalates, code 6, due to styrene, and code 7, because of the bisphenols, including BPA, unless labeled as "biobased" or "greenware."

4. Best Alternative to Plastic Bags

Zip-top bags have the benefit of laying flat and taking up minimal space in the fridge or freezer. But they're usually made of BPA-containing plastic and waste can be an issue. These large silicone bags are a cleaner, greener alternative that's heat- and cold-resistant and has an airtight zip-top.

At 16 ounces, the jars in this 12-pack are just the right size for a filling blended drink. Bonus: Unlike most canning jars, the lid is just a single piece, so you don't have to fiddle with a flat top and a ring.

Like the idea of packing lunches or dinners in individual compartments? These 36-ounce glass bento boxes are just the thing for you. The snap-on lids keep spillage at bay, and the tall dividers inside the containers keep foods separate (so the chicken won't get tossed in with your fruit!) — even if the container gets jostled around.

Storing Your Prepped Food

Good-quality containers with airtight lids will keep your prepped food fresher longer. But how long depends on what kind of food you're talking about. Heed Ayesta's general storage guidelines:

  • Veggies, beans or grains: Up to 5 days
  • Meat or poultry: Up to 3 days
  • Seafood: Up to 2 days
  • Smoothies: Up to 2 days
  • Salads: Up to 5 days when stored without the dressing.

Tip

“Pack salads with the wetter ingredients (like tomatoes or zucchini) at the bottom and drier ingredients on top,” Ayesta recommends.
