Glass vs. Plastic Meal Prep Containers: 3 Options Worth Considering

Glass or Plastic: Which Is Better for Meal Prep?

The answer nobody loves hearing: it depends.

Glass containers are heavier and usually more expensive, but they resist stains and odors and can offer more reheating versatility. For example, the Rubbermaid Brilliance glass bases we're reviewing below are oven-safe up to 450°F.

Plastic is lighter, easier to carry around, and often less expensive. That's a big advantage when your lunch bag already contains your water bottle, snacks, keys and approximately 14 things you forgot were in there.

So instead of declaring one material the winner, think about how you actually live.

Monday morning comes, you’re trying to get out the door, somebody needs something, your cafecito is getting cold, and suddenly that carefully planned lunch is still sitting in the refrigerator.

Amiga, we’ve been there.

Eating well during a busy week isn't always about finding another “perfect” meal plan. Sometimes, it's about making the meals you already enjoy easier to prepare, store, grab, and reheat.

And surprisingly, having the right containers can help.

So we looked at popular meal-prep and food-storage options and narrowed them down to three that solve three different problems: one for everyday versatility, one for those who prefer glass, and one for anyone who wants to start meal prepping without spending much.

But first, let's settle something.

🥇 Best Overall: Rubbermaid Brilliance Plastic

For someone who wants containers that can handle meal prep, leftovers, lunches and everyday refrigerator storage, Rubbermaid Brilliance is our most versatile pick.

The 14-piece set includes seven containers with lids in several sizes, from small half-cup containers to a large 9.6-cup container. The BPA-free Tritan plastic is stain- and odor-resistant, and the containers are stackable, freezer-safe, microwave-safe and top-rack dishwasher-safe.

Why we like it

The different sizes make this set useful beyond traditional meal prep.

You can use the larger container for tonight's pollo, smaller ones for salsa or toppings, and medium containers for tomorrow's lunch.

In other words, these don't have to become another “wellness purchase” taking up cabinet space after your motivation disappears on Wednesday.

They're everyday food-storage containers that can also make meal prep easier.

Best for: The amiga who wants one versatile food-storage system, especially if she regularly takes food to work.

Keep in mind: If you strongly prefer reheating or storing food in glass, skip ahead to our next pick.

🥈 Best Glass Upgrade: Rubbermaid Brilliance Glass

If you've been wanting to switch to glass containers, this is the option we'd consider first.

The Brilliance Glass set uses airtight, leak-resistant lids and stain- and odor-resistant glass. The containers are freezer-, microwave- and dishwasher-safe, and the glass bases can go into an oven up to 450°F. The lids also include microwave vents for reheating.

That oven capability is one of the biggest advantages here.

You can prep, refrigerate, reheat and serve using the same glass container in many situations—which means fewer dishes.

And any product that results in fewer dishes después de la cena deserves at least a moment of appreciation.

Why we like it

Glass doesn't hold onto food stains and odors the way some plastics can, which is especially nice when your meal prep involves tomato sauces, chiles, spices and all the flavorful things we have absolutely no intention of giving up.

Best for: The amiga who prefers glass and wants containers that transition easily from refrigerator to reheating and serving.

Keep in mind: Glass is heavier, and this option costs more. If you're carrying several containers back and forth to work every day, that matters.

🥉 Best Budget Meal-Prep Pick: Bentgo Prep

Maybe you're reading all this thinking:

“Amiga, I just need somewhere to put my lunch.”

Fair enough.

That's where Bentgo Prep makes sense.

The one-compartment set includes 10 trays and 10 lids. Each container holds four cups, has volume measurements built into the tray and is designed to stack. The trays can go in the microwave, freezer and top rack of the dishwasher; Bentgo recommends hand-washing the lids for best results.

They're also considerably lighter than glass, making them convenient for packing multiple meals.

Why we like it

This is the most straightforward “I'm going to prep my lunches this week” option of the three.

You don't need fancy compartments unless you want them. You don't need to organize your refrigerator like someone on TikTok. Cook your food, portion it, put the lids on, and move on with your Sunday.

Best for: Beginners, batch meal prepping and anyone who wants several containers without making a big investment.

Keep in mind: These are more meal-prep trays than premium everyday food-storage containers. Bentgo describes them as reusable up to 10 times, so if you're looking for a long-term storage system, we'd lean toward one of the Rubbermaid options instead.
