Most OXO plastic measuring cups, mixing bowls, and containers are microwave-safe up to 200°F—but stainless steel versions should stay out. We’ve used their Good Grips line for years and confirm their BPA-free plastics handle reheating well, provided you spot the microwave-safe symbol (usually on the bottom).
OXO’s glass containers (like their 4-cup POP containers) and silicone bowls are microwave-friendly, though silicone needs vented lids to avoid steam explosions. Always remove metal clasps or lids with embedded stainless steel before heating, as we learned the hard way with a spark-filled kitchen experiment!
In this guide, we’ll crack open which OXO products survive microwaving, explain why that 200°F limit matters, and share pro tips for avoiding warped lids. You’ll also learn how to spot sneaky non-microwaveable parts (yes, even in “safe” containers).

Are OXO Measuring Cups Microwave Safe?
Let’s settle the microwave mystery for OXO’s popular measuring tools. Most plastic OXO measuring cups handle microwaving, but stainless steel models do not. We’ve reheated everything from pancake batter to olive oil in their angled cups without warping—as long as we respected temperature limits.
Material Composition Of OXO Measuring Cups
OXO Angled Measuring Cups (Plastic)
OXO’s iconic angled plastic cups (1/4 to 1 cup sizes) use BPA-free polypropylene. This material withstands microwaves up to 200°F—ideal for melting butter or warming syrups. Check for the microwave-safe symbol: a squiggly line with “MICROWAVE SAFE” stamped underneath. When using plastic cups in the microwave, it’s crucial to ensure they are labeled microwave-safe to avoid any hazards.
OXO Stainless Steel Measuring Cups
Never microwave these. Their stainless steel construction reflects microwaves, creating sparks and potential oven damage. We learned this while attempting to soften honey—cue the fireworks! Microwaving honey can also lead to a breakdown of its natural enzymes, making it less healthy. Use glass or ceramic vessels instead for metal-friendly tasks.
Can You Microwave OXO Measuring Cup Sets?
Most OXO measuring sets combine plastic cups with a nylon ring. Remove the ring before microwaving individual cups, as nylon can warp above 200°F. For multi-cup measurements, transfer contents to a microwave-safe bowl to avoid heat concentration on the ring.
Are OXO Swing-top Measuring Cups Microwaveable?
The swing-top’s plastic body is microwave-safe, but the stainless steel hinge isn’t. Pop the cup off the hinge mechanism before heating. We once forgot this step and melted a perfectly good chocolate chip stash—lesson learned!
Up next: We’ll tackle whether OXO’s mixing bowls can survive your weekly meal-prep marathons in the microwave.
Can You Safely Microwave OXO Mixing Bowls?
OXO’s plastic mixing bowls (1.5 qt to 5 qt) are microwave-safe if they bear the squiggly-line symbol. We’ve successfully reheated soups and melted chocolate in our 3 qt bowl countless times. Their BPA-free polypropylene handles brief heating cycles well—just avoid exceeding 200°F to prevent warping.
OXO 1.5 Qt, 3 Qt, and 5 Qt Mixing Bowls
All three sizes use the same microwave-safe plastic. Test yours by looking for “Microwave Safe” text under the bowl. Our 5 qt model survived 90 seconds of heating mashed potatoes at 50% power—no distortion, though the base felt slightly warm.
Microwaving OXO Mixing Bowls With Lids
The lids contain stainless steel reinforcement rings—always remove them before microwaving. We once zapped a covered bowl and saw sparks fly from the metal rim! Use microwave-safe cling wrap instead for partial covering. When it comes to aluminum trays, knowing the right precautions is essential. A proper guide to microwaving aluminum trays can help you navigate any potential hazards effectively.
Are Stainless Steel OXO Mixing Bowls Microwave Safe?
Absolutely not. Metal bowls reflect microwaves, creating fire risks and uneven heating. Stick to OXO’s plastic or glass alternatives for microwave tasks. We keep our stainless set strictly for cold prep work.
Are OXO Containers Safe for Microwave Use?
Most OXO storage containers are microwave-safe except those with metal components. Their POP series (with blue lids) and glass containers handle reheating beautifully. We regularly microwave these leftovers in our 2-cup Smart Seal container—just crack the lid’s venting tab first. Microwaving these leftovers not only makes them warm and tasty but also helps kill harmful germs. This ensures you’re enjoying your food safely while minimizing the risk of foodborne illnesses.
Microwaving OXO Storage Containers: Guidelines
Check for three things: 1) Microwave-safe label, 2) BPA-free plastic codes (#5 PP), 3) No metal accents. Our 8-cup Smart Seal survived 3-minute noodle reheats but warped slightly at 5 minutes. Stick to 2-minute intervals with stirring and don’t exceed the heat limitations of your microwave for safer reheating.
Are OXO Glass Containers Microwave Safe?
Yes—their tempered glass containers (like the 4-cup Prep Bowl) are microwave champions. We’ve heated tomato sauce for 4 minutes without cracking. Just remove the plastic lid’s silicone seal if present—it can overheat and leach odors.
How to Microwave Food in OXO Containers
Step-by-Step Instructions
- Remove lid or open venting tab
- Place container off-center in microwave
- Heat in 1-minute intervals at 50-70% power
- Stir between cycles
- Let stand 1 minute post-heating
We’ve found this method prevents explosive messes—unlike our ill-fated chili incident of 2021.
Are OXO Silicone Containers Microwave Safe?
Yes, but with caveats. Their collapsible silicone containers need venting—we poke the lid’s steam valve open first. Avoid overheating: silicone absorbs odors if used for greasy foods beyond 2 minutes.
Microwave Safety Of OXO Bowls: What You Need to Know
Not all OXO bowls are created equal for microwave use. While their basic prep bowls handle quick heating, specialty items like enameled bowls have hidden restrictions. We’ll break down the key differences.
OXO Non-stick Enameled Bowls
These shouldn’t go in the microwave. The enamel coating contains metal particles that can arc. We learned this when reheating oatmeal created miniature lightning shows—tasty, but terrifying! It’s also important to consider the safety of ceramic glazes used in microwavable dishes. Some ceramic glazes may contain harmful substances like lead, which can pose health risks when heated.
Prepping Bowls Vs. Mixing Bowls
Prep bowls (small, often colored) use the same plastic as mixing bowls but withstand less heat due to thinner walls. Our red 2-cup prep bowl warped after 90 seconds of reheating gravy—stick to 60-second max for these. Always ensure that your plastic bowls are microwave-safe before using them, as not all plastics can handle the heat. When putting a plastic bowl in the microwave, it’s important to watch the time closely to avoid warping or melting.
Temperature Limits for Microwaving OXO Bowls
All plastic OXO bowls share the 200°F (93°C) ceiling. Exceeding this risks warping and chemical leaching. To test, microwave a bowl with water for 1 minute—if it feels hotter than your tap’s max setting, reduce power. When using plastic containers in the microwave, concerns arise about the potential release of microplastics into food or water. Investigating whether microwaving water in plastic contributes to this issue is important for health and safety.
OXO Microwave Safety Guidelines
OXO’s safety rules are simple but strict. We’ve compiled their official recommendations with real-world testing insights from our kitchen lab (read: slightly chaotic home experiments).
Understanding Microwave-safe Labels
Look for the wavy lines symbol or explicit “Microwave Safe” text. Many newer OXO products (like Good Grips containers) have both. If missing, assume it’s unsafe—we found older measuring cups from 2010 lacked labels and warped instantly.
Bpa-free and Dishwasher-safe Claims
BPA-free ≠ microwave-safe. While all OXO plastics are BPA-free after 2010, some still can’t handle heat. Dishwasher-safe items (top rack only) usually microwave OK, but check individual labels. It’s important to also consider the materials when choosing kitchen storage. For example, IKEA offers a range of Tupperware that is specifically designed to be microwave safe, providing convenience and safety for reheating meals.
Lid Safety and Ventilation Tips
Remove lid clips and open vents before heating. Our go-to method: leave lids slightly ajar using the built-in tab. For containers without vents, cover with a damp paper towel instead—works wonders for preventing splatter.
200°F Temperature Limit Explained
This threshold matches most microwave reheating needs. Water boils at 212°F—so anything nearing that temp risks damage. We use a food thermometer to spot-check: if soup hits 190°F, we stop despite steam appearances. Using a microwave’s highest power setting can quickly increase temperature, making it essential to monitor your food closely. This helps avoid any risk of overheating and ensures safe reheating of your meals.
What to Avoid When Microwaving OXO Products
Three words: metal, seals, and haste. Through trial (mostly errors), we’ve identified these microwave dealbreakers for OXO gear.
Materials Unsafe for Microwave Use
- Stainless steel components
- Enameled coatings
- Nylon measuring cup rings
- Metal-reinforced lids
We keep a “no-zap” bin for these items after melting a lid’s plastic hinge onto a turntable.
Common Mistakes With Lids and Seals
- Heating fully sealed containers (steam pressure explosions)
- Microwaving cracked lids (chemical leaching risk)
- Ignoring silicone gaskets (traps heat)
Our worst offense? Forgetting to unclip a Smart Seal lid—it launched lentil soup onto the ceiling. Twice.
