Yes, many Bentgo boxes are designed with microwave-safe components, but specific models and parts require careful attention to their heating instructions.
Navigating the world of meal prep containers can feel like a culinary puzzle, especially when it comes to reheating your delicious creations. We all want our packed lunches to be as convenient as they are tasty, and a quick zap in the microwave often feels like the simplest solution. Let’s break down the facts about Bentgo boxes and how to safely warm your meals without compromising your food or your container.
The Core Question: Bentgo’s Microwave Guidelines
Bentgo designs its lunchboxes with practicality and durability in mind, which often includes microwave compatibility for certain parts. The key lies in understanding which specific components are safe for microwave use and which are not. Not all plastics are created equal when exposed to microwave energy, and Bentgo uses a combination of materials to achieve its leak-proof and compartmentalized designs.
Generally, the inner food trays of many Bentgo models are made from polypropylene (PP) plastic, which is widely recognized as microwave-safe. This material can withstand the heat generated by microwave ovens without leaching harmful chemicals into your food or deforming. However, the outer shells and lids often incorporate different plastics or silicone seals that may not be suitable for high heat.
What “Microwave-Safe” Truly Means
“Microwave-safe” indicates that a material will not melt, warp, or release harmful chemicals when exposed to microwave radiation under normal heating conditions. For plastics, this usually means they are made from materials like polypropylene (PP) or specific types of ceramics or glass. It’s important to remember that even microwave-safe plastics can degrade over time with excessive or improper heating, so moderation and adherence to manufacturer guidelines are crucial.
When you see a microwave-safe symbol – often a microwave with wavy lines or a dish with wavy lines – it signifies that the item has been tested and deemed suitable for use in a microwave. Bentgo clearly labels its products and provides instructions to guide users on safe reheating practices.
Understanding Bentgo Models & Materials
Bentgo offers a range of lunchboxes, each with slightly different features and material compositions. Knowing your specific model helps ensure you’re using it correctly for reheating.
Bentgo Classic & Bentgo Fresh
These popular models typically feature an outer shell made from ABS plastic and inner trays made from food-grade polypropylene (PP) plastic. The silicone seals, essential for leak-proofing, are also part of the design. For the Bentgo Classic and Bentgo Fresh, the inner tray is microwave-safe. This means you can remove the tray from the outer shell and heat your food directly in it. The outer shell, however, should never be placed in the microwave. The silicone-lined lid should also be removed or at least unsealed to allow steam to escape during heating, preventing pressure buildup and potential damage to the lid or tray.
Bentgo Kids & Bentgo Kids Brights
Designed for smaller appetites, these boxes share similar material compositions with the Classic and Fresh models, often featuring an ABS outer shell and PP inner trays. The Bentgo Kids inner tray is microwave-safe for reheating food. Just like the adult versions, the outer shell and the sealed lid should not go into the microwave. The compartments are sized for children’s portions, making reheating quick and efficient when done correctly. Always ensure the lid is removed or vented to prevent steam accumulation.
Bentgo Glass & Bentgo Prep
Bentgo Glass models incorporate borosilicate glass bases, which are inherently microwave-safe, oven-safe, and freezer-safe. This makes them incredibly versatile for reheating. The lids for Bentgo Glass containers are typically made from PP plastic with silicone seals and are generally not microwave-safe due to the seals and potential for warping. Always remove the lid before microwaving food in a Bentgo Glass base. Bentgo Prep containers are designed for batch cooking and often come with PP plastic bases and lids, with the bases being microwave-safe and the lids requiring removal or venting.
Best Practices for Microwaving Food in Bentgo Boxes
Even with microwave-safe components, proper technique is essential for safe and effective reheating. Incorrect microwaving can lead to unevenly heated food, damaged containers, or even food safety issues.
- Remove Non-Microwaveable Parts: Always separate the microwave-safe inner tray from the outer shell. Remove the lid entirely or at least lift a corner of the lid to vent steam.
- Short Heating Intervals: Microwave food in short bursts, typically 1-2 minutes at a time, especially for the first round. This prevents overheating the plastic and allows for better temperature control.
- Stir for Even Heating: Microwaves often heat unevenly, creating “cold spots” where bacteria can survive. Pause heating to stir your food thoroughly, especially dense items, to distribute heat evenly.
- Check Temperature: Use a food thermometer to ensure food reaches a safe internal temperature of 165°F (74°C). This is critical for preventing foodborne illness.
- Avoid Overheating: Excessive microwave power or prolonged heating can damage even microwave-safe plastics over time, leading to warping or degradation.

Why Some Parts Aren’t Microwave-Safe
The different materials used in Bentgo boxes serve specific functions, and not all are designed to withstand microwave energy. The outer shells of most Bentgo models are made from ABS plastic, chosen for its rigidity, impact resistance, and aesthetic appeal. While excellent for protecting your lunch, ABS plastic is not formulated to handle the internal temperatures generated by microwave heating. Exposing it to microwave radiation can cause it to warp, melt, or potentially leach chemicals.
Similarly, the silicone seals, which are key to Bentgo’s leak-proof design, can degrade or lose their elasticity with repeated exposure to high microwave heat. While silicone itself is generally heat-resistant, the combination with plastic lids or the stress from steam pressure can compromise its integrity over time. Removing the lid or venting it properly protects these seals and prevents pressure buildup that could damage the container or cause spills.
Beyond the Microwave: Alternative Reheating Methods
Sometimes, the microwave isn’t the best tool for the job, or you might have a Bentgo box that isn’t fully microwave-compatible. Fortunately, several other methods can bring your meal back to a delicious, warm state.
- Transfer to Microwave-Safe Dish: The simplest alternative is to transfer your food from the Bentgo box to a ceramic plate or glass bowl that is explicitly designed for microwave use. This ensures maximum safety and container longevity.
- Oven Reheating: For foods that benefit from crisping or more even heating, an oven can be a great option. Transfer your meal to an oven-safe dish (like a ceramic baking dish or a Bentgo Glass base without its lid) and reheat at a moderate temperature (e.g., 300-350°F / 150-175°C) until heated through. This works particularly well for casseroles, roasted vegetables, or baked goods.
- Stovetop Reheating: Many foods, especially saucy dishes, stir-fries, or soups, can be effectively reheated on the stovetop. Use a pan or pot over medium-low heat, stirring frequently to prevent sticking and ensure even warming. A splash of water or broth can help prevent drying out.
| Reheating Method | Best For | Considerations |
|---|---|---|
| Microwave (Bentgo Tray) | Quick single servings, most leftovers | Remove outer shell, vent lid, stir frequently. |
| Oven (Separate dish) | Casseroles, baked items, foods needing crisping | Slower, requires oven-safe dish, preheating time. |
| Stovetop (Separate dish) | Soups, stews, saucy dishes, stir-fries | Requires constant attention/stirring, prevents drying. |
Maintaining Your Bentgo Box’s Longevity
Proper care extends the life of your Bentgo box, ensuring it remains a reliable companion for your meal prep. Always consult the specific cleaning instructions for your model, as some parts may be top-rack dishwasher safe while others require hand washing.
- Dishwasher Safety: Many Bentgo inner trays are top-rack dishwasher safe. The outer shells, however, are often recommended for hand washing to preserve their finish and structural integrity. High heat from the dishwasher’s drying cycle can sometimes affect non-microwave-safe plastics.
- Hand Washing: For parts not suitable for the dishwasher, use warm, soapy water and a soft sponge. Avoid abrasive scrubbers or harsh chemicals that can scratch the surface or degrade the materials.
- Drying Thoroughly: Ensure all components, especially silicone seals, are completely dry before reassembling and storing. This prevents mold or mildew growth and helps maintain the integrity of the seals.
- Inspecting for Wear: Regularly check your Bentgo box for cracks, warping, or discoloration, particularly on the inner trays. Any signs of damage, especially to the plastic, suggest it might be time for a replacement to ensure food safety and container performance.
Food Safety First: Storing & Reheating Leftovers
Beyond the container itself, safe food handling is paramount when packing and reheating meals. Improper storage and reheating are common causes of foodborne illness.
When packing leftovers, cool food rapidly within two hours of cooking. Divide large portions into smaller, shallow containers to speed up the cooling process before refrigerating. Food should be stored in the refrigerator at 40°F (4°C) or below and consumed within 3-4 days for most items. For detailed guidelines on safe food handling and storage, the USDA offers comprehensive resources.
When reheating, always ensure food reaches an internal temperature of 165°F (74°C) as measured with a food thermometer. This temperature effectively kills most harmful bacteria. Reheat food only once; repeated reheating can compromise food quality and safety. If you are unsure about the safety of a reheated meal, it’s always best to discard it. The FDA also provides extensive information on safe food temperatures and practices.
