5 Best Plastic Meal Prep Containers for Microwave and Freezer
Quick Answer
The 5 best plastic meal prep containers for microwave and freezer use are the Prep Naturals 3-Compartment Containers, Rubbermaid Brilliance Food Storage, Bentgo Meal Prep, GoodCook Meal Prep Containers, and OXO Good Grips Smart Seal. All five are BPA-free, freezer-safe, and microwave-safe with the lid removed or vented. Your best pick depends on whether you need divided compartments, stackability, or a tighter budget.
Key Takeaways
- All five containers on this list are BPA-free and rated for both microwave and freezer use.
- Always remove or vent the lid before microwaving plastic containers to avoid pressure buildup.
- Divided compartments help keep foods separate, which matters most for meal prepping multiple components at once.
- Freezer-safe containers should have a tight seal to prevent freezer burn on proteins and grains.
- Rectangular containers stack more efficiently in the fridge and freezer than round ones.
- Container capacity matters: most single-meal preps need at least 28 to 32 oz of space.
- Cheaper containers can warp after repeated microwave cycles; mid-range picks hold up better over 6 to 12 months of regular use.
- Glass is heavier but more durable long-term; plastic wins for portability and cost.
- Always check the recycling number on the bottom: #5 polypropylene (PP) is the safest plastic for food storage and heat.
- Matching lids and a consistent container size make stacking and storage far easier week to week.
Why Plastic Meal Prep Containers Still Make Sense in 2026
Plastic meal prep containers remain one of the most practical choices for busy adults who cook in batches. They are lightweight, shatter-resistant, affordable, and widely available. When you are carrying lunch to work or stacking 5 to 7 days of meals in a tight freezer, the weight difference between plastic and glass matters.
That said, not all plastic containers are equal. The ones worth buying share a few key traits:
- BPA-free construction, ideally made from polypropylene (#5 PP)
- Microwave-safe rating (with lid vented or removed)
- Freezer-safe rating down to at least 0°F (-18°C)
- Leak-resistant lids for sauces and dressings
- Stackable design to save fridge and freezer space

The 5 Best Plastic Meal Prep Containers for Microwave and Freezer: Full Reviews
Here are the five containers I recommend most for people who meal prep regularly. Each one has been evaluated for durability, seal quality, microwave performance, and freezer reliability.
1. Prep Naturals 3-Compartment Containers (Best Overall)
Best for: Meal preppers who want divided sections and a budget-friendly price per container.
These are a staple in my weekly prep routine. The 3-compartment design keeps proteins, grains, and vegetables separate without needing multiple containers. They hold 36 oz total, which is enough for a full lunch or dinner portion.
What I like:
- Made from #5 polypropylene, which is one of the safer plastics for food use
- Lids snap on firmly and hold up well in a bag or backpack
- Freezer-safe and microwave-safe with the lid cracked open
- Usually sold in 20-pack sets, which brings the per-container cost down significantly
What to watch:
- The dividers do not create a watertight seal between compartments, so wet foods can bleed into dry ones
- Lids can warp slightly after 50 or more microwave cycles at high heat
Choose this if you meal prep 4 to 5 days of lunches at a time and want compartments without spending much per container.
2. Rubbermaid Brilliance Food Storage (Best for Leak-Proofing)
Best for: Anyone who transports saucy meals or soups and needs a genuinely leak-resistant seal.
Rubbermaid Brilliance containers use a four-latch lid system with a built-in gasket. In practical terms, this means you can toss one in a bag without worrying about a spill. They come in sizes ranging from 1.3 cups to 9.6 cups, so you can match the container to the meal.
What I like:
- Crystal-clear plastic makes it easy to see contents without opening
- 100% leak-proof when all four latches are closed (Rubbermaid’s own claim, verified by widespread user testing)
- Dishwasher-safe on the top rack, which saves time
- Stacks cleanly because of the flat lid design
What to watch:
- Pricier than basic containers, especially for larger sets
- The four-latch system takes a few seconds longer to open and close, which adds up if you are packing multiple containers
Choose this if you carry meals with sauces, curries, or soups and cannot risk a leak in your bag.
For high-protein meals that work well in these containers, our chicken burrito bowl meal prep and salmon rice bowl meal prep recipes are solid starting points.
3. Bentgo Meal Prep Containers (Best Divided Option)
Best for: People who want bento-style compartments in a durable, slightly more premium plastic container.
Bentgo’s meal prep line offers 2-compartment and 5-compartment options. The 5-compartment version is particularly useful for prepping balanced plates with a protein, two vegetables, a grain, and a small snack or sauce all in one container.
What I like:
- Thicker plastic than most budget options, which holds up better over time
- Microwave-safe with the lid removed
- Freezer-safe down to -4°F (-20°C)
- Lids have a secure snap that does not pop open in a bag
What to watch:
- The 5-compartment version is not ideal for large portions; each section is relatively small
- Slightly bulkier than single-compartment containers, so they take more freezer space
Choose this if you want variety in a single container and do not mind a slightly larger footprint.

4. GoodCook Meal Prep Containers (Best Budget Pick)
Best for: Beginners or anyone who wants to test meal prepping without spending much upfront.
GoodCook containers are widely available at grocery and big-box stores, which makes them easy to replace or add to. They come in 2-cup, 4-cup, and 6-cup sizes and are sold individually or in small sets.
What I like:
- Very affordable, often under $2 per container
- BPA-free and labeled microwave and freezer safe
- Simple snap lid that is easy to open one-handed
- Lightweight and easy to carry multiple at once
What to watch:
- The lids are not leak-proof, so these are better for dry or semi-dry meals
- Thinner plastic means they may warp or stain faster than mid-range options
- Not the best choice for long-term freezer storage beyond 4 to 6 weeks
Choose this if you are just starting out with meal prep and want to try the habit before investing in pricier containers.
If you are new to batch cooking, our high-protein meal prep for beginners guide pairs well with this container pick.
5. OXO Good Grips Smart Seal (Best for Freezer-Heavy Meal Prep)
Best for: Anyone who preps large batches and relies heavily on the freezer for storage beyond 5 days.
OXO Smart Seal containers have a one-press lid mechanism that creates an airtight seal, which is especially valuable for freezer storage. Airtight seals reduce freezer burn significantly, which means your prepped proteins and grains stay fresher longer.
What I like:
- Airtight one-press lid is genuinely easy to use
- Available in sizes from 0.6 qt to 6 qt, which covers everything from single snacks to full batch meals
- Freezer-safe and microwave-safe (lid removed)
- Clear body with measurement markings on the side
What to watch:
- Higher price point than most plastic options
- The lid mechanism can wear out after 12 to 18 months of heavy daily use
- Rectangular shapes stack well, but the round options waste some shelf space
Choose this if you prep high-protein freezer meals in bulk and need containers that protect food quality over several weeks.

How to Choose the Right Plastic Meal Prep Container for Your Needs
Choosing the right container comes down to four practical questions:
- How long will you store the food? Fridge storage up to 4 to 5 days is fine for most containers. Freezer storage beyond 2 weeks calls for an airtight seal like the OXO Smart Seal.
- Do you need compartments? If you prep full plates with multiple components, divided containers save you from using multiple boxes per meal.
- How do you transport meals? If you carry meals in a bag, prioritize leak-resistant lids. If you eat at home, a basic snap lid is fine.
- What is your budget? A 20-pack of basic containers can cost under $20, while premium sets with airtight lids run $40 to $80 for a similar quantity.

What Makes a Plastic Container Safe for Microwave and Freezer Use?
A plastic container is safe for microwave and freezer use when it meets specific material and design standards. The two most important factors are the plastic resin type and the temperature rating printed on the container.
Look for these on the label or bottom of the container:
- Recycling symbol #5 (PP or polypropylene): This is the most heat-stable common food plastic. It does not leach chemicals at microwave temperatures the way lower-grade plastics can.
- “Microwave-safe” label: This means the container has been tested to withstand microwave heat without warping or releasing harmful compounds, but it does not mean the food heats evenly.
- “Freezer-safe” label: This means the plastic stays intact and does not crack at freezing temperatures, typically down to 0°F (-18°C) or lower.
- “BPA-free” label: Bisphenol A (BPA) is a chemical used in some older plastics that has raised health concerns. All five containers on this list are BPA-free.
Common mistake: Microwaving with the lid fully sealed. Even microwave-safe lids can trap steam and create pressure. Always crack the lid or remove it before heating.
How to Store and Care for Plastic Meal Prep Containers
Proper care extends the life of your containers significantly. Here are the practical steps I follow:
- Wash before first use with warm soapy water or run through the dishwasher.
- Hand wash lids when possible. Dishwasher heat can warp lids faster than the containers themselves.
- Avoid high-fat foods in the microwave inside plastic containers when possible. High-fat foods like bacon or cheese can reach temperatures that exceed the container’s safe range.
- Do not stack containers with food inside in the freezer if the lids are not airtight. The weight can crack thinner lids.
- Replace containers that show cracks, deep scratches, or warping. Scratched plastic can harbor bacteria and may leach more readily when heated.
- Label containers with the date and contents using masking tape and a marker. Most prepped meals are best within 4 to 5 days in the fridge or 2 to 3 months in the freezer.

FAQ: Plastic Meal Prep Containers for Microwave and Freezer
Q: Can I put plastic meal prep containers directly in the microwave?
Yes, if they are labeled microwave-safe. Always remove or vent the lid first to prevent steam pressure buildup. Avoid microwaving high-fat foods at full power for long periods.
Q: How long can I store food in plastic containers in the freezer?
Most cooked proteins and grains stay good for 2 to 3 months in the freezer when stored in airtight containers. Quality degrades after that, though food may still be safe to eat.
Q: What plastic number is safest for food storage?
#5 polypropylene (PP) is the safest and most heat-stable common food-grade plastic. Avoid #3 (PVC) and #6 (PS) for food storage.
Q: Are BPA-free containers completely safe?
BPA-free means the container does not contain bisphenol A. Most reputable brands have removed BPA from their products. If you want to avoid all plastic-related concerns, glass containers are an alternative. See our best glass meal prep containers guide.
Q: Can plastic containers crack in the freezer?
Thinner or lower-quality plastics can crack when exposed to very low temperatures, especially if they are full and the contents expand as they freeze. Leave 1/2 to 1 inch of headspace when freezing liquids or saucy meals.
Q: How many containers do I need to start meal prepping?
For 4 to 5 days of lunches and dinners, you need roughly 8 to 10 containers of the same size. Starting with a 10-pack is a practical entry point.
Q: Can I use plastic containers for hot food right off the stove?
Let food cool for 10 to 15 minutes before sealing it in a plastic container. Sealing very hot food traps steam, raises internal pressure, and can warp lids over time.
Q: Is it safe to freeze soup in plastic containers?
Yes, if the container is rated freezer-safe. Leave headspace for expansion and use an airtight container to prevent freezer burn.
Q: How do I remove stains from plastic containers?
Soak in a mixture of 1 tablespoon baking soda and 1 cup warm water for 30 minutes, then scrub with a soft brush. Tomato-based and turmeric stains are the hardest to remove from plastic.
Q: What is the difference between meal prep containers and regular food storage containers?
Meal prep containers are designed for portioned, single-serving meals and often come in uniform sizes for easy stacking. Regular food storage containers vary more in shape and are designed for storing bulk ingredients rather than individual meals.
