UltraPro® Casserole Pan with Cover | 3.7 Qt / 3.5 L

No, you’re not dreaming — yes, it’s truly oven-safe Tupperware. Elegant, lightweight, and stackable, this is the ultimate all-in-one cooking, storing, and serving solution. Fridge, freezer, microwave, oven, and dishwasher safe — and gorgeous on the table.

• All-in-One Oven-Safe Casserole Pan with Cover: Versatile, lightweight material resists temperatures from -13°F to 482°F (-25°C to 250°C). Perfect for cooking in the oven or microwave, storing in the fridge or freezer, and serving directly at the table.
• Lightweight & High-End Material: Lighter than ceramic, clay, glass, or cast iron ovenware — easier to handle for daily meal prep while delivering professional results.
• Rounded Corners & Domed Cover for Even Cooking: Rounded base corners and domed cover optimize heat distribution, reduce hot spots, and prevent overcooking for consistent results.
• Non-Stick Surface for Healthier Cooking: Naturally non-stick material makes healthy, low-fat cooking easier and reduces the need for excess oil or butter.
• Built-In Steam Release Vents: Side vents on both base and cover prevent steam buildup, regulate humidity, allow browning, and maintain optimal moisture.
• Versatile Rectangular Design: Ideal for savory or sweet dishes: meatloaf, baked fish, lasagna, potato gratin, roasted vegetables, quiches, loaf cakes, cheesecakes, breads, fruit crumbles, and more. Rectangular shape lets you place two pans side-by-side on most oven racks for tandem cooking.
• Nestable & Space-Saving Design: Base and cover nest perfectly with other UltraPro pieces for compact storage. Instructions engraved inside the cover and on the base bottom.

Use and Care

Cooking & Reheating

• Oven-safe up to 482°F/250°C (do not exceed max temperature or cook longer than 2 hours). Always preheat the oven and place UltraPro inside after preheating.
• Never use the grill/broiler function or place under direct grill.
• Microwave-safe; also suitable for “Tandem Cooking” — start in microwave, finish in oven for faster roasted/grilled results.
• Can be used in steam ovens.
• Keep at least 2 in / 5 cm away from oven walls and heating elements.
• Always use oven mitts and grip both handles when removing from oven or microwave.

Filling & Freezing

• Prepare and freeze meals in advance; defrost and reheat in the microwave — all in the same container.
• Covered design is perfect for storing leftovers in the fridge or freezer.

Cleaning & Storage

• Dishwasher-safe.
• Use a soft sponge or Tupperware microfiber cloth. Do not use metal or sharp utensils.
• Never use aerosol non-stick sprays (use butter + flour instead).
• For burnt-on residue: soak in 4 tbsp dishwasher detergent + 5 L (10 pints) hot water for at least 2 hours.
