Glasslock 18-Piece - Best Overall
Glasslock with the four-clip silicone lids is the set I use every week. The lids actually seal liquid, the glass survives going straight from fridge to microwave, and the rectangular shapes stack neatly in my fridge shelf. I have had the same containers for over two years through hundreds of dishwasher cycles and zero have cracked or warped. The starter pack of 18 pieces is enough for a week of prep for two people.

When I first started meal prepping, I thought any old container would do. I was wrong. After cycling through dozens of options-from mismatched Tupperware to trendy glass sets-I’ve landed on a few that actually survive my weekly routine. No plastic lids that crack, no glass bases that shatter, no weird smells after a few uses. Here’s what I actually pack my lunches in, compared head-to-head.
The Contenders
I tested five popular meal prep containers over the past six months: Glasslock 3-Piece Set, Prep Naturals 3-Compartment, Bentgo Fresh, Rubbermaid Brilliance, and a generic BPA-free plastic set from Target. I packed everything from soups to salads to stir-fries, and I rated them on durability, leak resistance, microwave safety, dishwasher friendliness, and how they handled reheating. Here’s the breakdown.
| Feature | Glasslock | Prep Naturals | Bentgo Fresh | Rubbermaid Brilliance | Generic Plastic |
|---|---|---|---|---|---|
| Material | Tempered glass | Plastic | Plastic | Plastic | Plastic |
| Lid seal | Snap-lock, silicone gasket | Snap-lock, no gasket | Snap-lock, silicone gasket | Snap-lock, silicone gasket | Snap-lock, no gasket |
| Leak resistance | Excellent | Good (if closed properly) | Excellent | Excellent | Poor |
| Microwave safe | Yes (lid off) | Yes | Yes (lid vented) | Yes | Yes |
| Dishwasher safe | Yes | Yes (top rack) | Yes | Yes | Yes (top rack) |
| Durability | High (glass can break) | Medium (scratches) | Medium (cracks) | High | Low (warping) |
| Portion control | Single compartment | 3 compartments | 2 compartments | Single compartment | Single compartment |
| Price range | Mid | Low | Mid | Mid | Low |
Glasslock: The Heavy Lifter
If you don’t mind a little weight, Glasslock is the gold standard. The tempered glass base is sturdy and doesn’t stain or smell. The lid has a silicone gasket that creates a tight seal-I’ve tossed these in my bag with soup and never had a leak. They go from freezer to microwave (lid off) to dishwasher without issue. The downside? They’re heavy. And if you drop one, it might shatter (I’ve lost one that way). But for reheating leftovers, glass is superior-no plastic leaching, no weird taste. I use these for anything saucy or for when I want to reheat directly in the container.
Prep Naturals 3-Compartment: Budget-Friendly Portion Control
These are my go-to for lunches where I want to keep components separate-like a protein, a carb, and a veggie. The plastic is lightweight and the three compartments help with portion control. The lids snap on securely, but there’s no gasket, so they can leak if you tip them sideways. I’ve had a few develop cracks after repeated dishwasher cycles. They’re cheap enough to replace, but not built to last. Best for dry-ish meals or when you’re careful with transport.
Bentgo Fresh: The Leak-Proof Champ
Bentgo Fresh containers have a silicone gasket that makes them virtually leak-proof. I’ve carried yogurt with fruit in the same container and had zero spills. The two-compartment design is great for a main and a side. The plastic is BPA-free and holds up well, but the lids can be a bit stiff to close. They’re microwave-safe with the vent open, and dishwasher-safe on the top rack. My only complaint: the compartments are a bit small for a big appetite. But for a standard lunch, they’re perfect.
Rubbermaid Brilliance: The All-Rounder
Rubbermaid Brilliance containers are made of a durable plastic that doesn’t stain or warp. The lid has a four-point seal that’s very reliable-I’ve never had a leak. They’re clear, so you can see what’s inside, and they stack neatly. They’re microwave and dishwasher safe, and they handle reheating well without getting too hot to touch. The only downside is that they’re single-compartment, so if you want to keep foods separate, you need to use dividers or multiple containers. They’re a solid choice for everyday use.
Generic Plastic Set: The Cautionary Tale
I bought a cheap 10-piece set from Target thinking it would be a good starter. Within a month, the lids were warping in the dishwasher, the bases had scratches, and one lid cracked. They leaked if I put anything liquid in them. I ended up tossing them. They’re fine for dry snacks or if you’re on a tight budget, but they won’t last. Save your money and invest in something better.
My Final Picks
After all this testing, here’s what I actually use: For soups and saucy meals, I reach for Glasslock. For everyday lunches with separate components, I use Prep Naturals (I just pack them upright in my bag). For anything that needs to be leak-proof, Bentgo Fresh is my choice. And for a versatile, durable option, Rubbermaid Brilliance is hard to beat. Avoid the cheap plastic sets-they’re not worth the savings.
Meal prep containers are a personal choice, but these are the ones that have earned a permanent spot in my kitchen. Happy prepping!

Glasslock 18-Piece - Best Overall
Glasslock with the four-clip silicone lids is the set I use every week. The lids actually seal liquid, the glass survives going straight from fridge to microwave, and the rectangular shapes stack neatly in my fridge shelf. I have had the same containers for over two years through hundreds of dishwasher cycles and zero have cracked or warped. The starter pack of 18 pieces is enough for a week of prep for two people.

Pyrex Simply Store - Best Oven-Safe
Pyrex containers go in the oven, which the silicone-lid Glasslock cannot do. I use the Pyrex rectangular dishes for baked pasta and roasted veggies that go straight into the lunch rotation. The blue lids are not as leak-tight as Glasslock so reserve these for solid foods. Glass is heavier in a tote, but the oven compatibility earns the spot.
Rubbermaid Brilliance - Best Plastic
The Brilliance line uses Tritan plastic which resists staining from tomato sauce and curries far better than older Rubbermaid lines. I use these for cold lunches, dressings, and snacks where weight matters. Lids snap on with four corner latches and they have not leaked a single time in my testing. Avoid microwaving with the lid clipped, which is the rule for any plastic container.

Bentgo Stackable - Best Bento Style
Bentgo divides meals into separate compartments without letting flavors mix. I love this for kid lunches and for portion-controlled adult lunches where you want protein, grain, and veg kept apart. The stackable variant takes less fridge space than wider bentos. Heat compatibility is limited so use them cold or transfer to a plate before microwaving.
LunchBots Trio - Best Stainless Steel
If you want to keep plastic out of your food entirely, LunchBots stainless containers are excellent. The Trio has three compartments and a single lid. Not leak-proof for liquid soup, but for sandwich and salad lunches they are durable, recyclable, and never stain. Cannot microwave but if you bring cold lunches or eat at a workplace that has microwavable plates available, they are great.
How to choose
What to consider
Start by thinking about how you will reheat. If you microwave at your desk, get glass with vented silicone lids. If you eat cold lunches, plastic or stainless work and weigh less in a bag. Look for square or rectangular shapes because they fridge-stack better than round. Watch out for lid materials. Polypropylene lids crack within a year. Silicone gasket lids last several years. Avoid any container without a clear microwave or dishwasher safety mark stamped on the bottom. Buy a set rather than mixing brands so the lids interchange.
Common questions
Yes, but remove the lid first. The glass base is microwave-safe.
Yes, but place them on the top rack to avoid warping.
No, they have a silicone gasket that makes them leak-proof when closed properly.
Prep Naturals 3-compartment containers are designed for portion control with separate sections.
