Introduction
Thank you for choosing the Tupperware Ultra Pro Casserole Set. This manual provides essential information for the safe and effective use, care, and maintenance of your new 2.1 Quart and 3.7 Quart Ultra Pro baking dishes. Please read these instructions thoroughly before first use and retain them for future reference.
General Safety Instructions
- Maximum Temperature: Do not exceed 400°F (200°C) when using in a conventional oven.
- No Stovetop or Broiler: Ultra Pro products are not designed for stovetop use or under a broiler. Direct heat sources can cause damage.
- Avoid Sharp Utensils: Use only plastic, silicone, or wooden utensils to prevent scratching the non-stick surface.
- Handle with Care: Always use oven mitts or gloves when handling hot Ultra Pro dishes.
- Preheating: Do not preheat empty Ultra Pro dishes in the oven. Always place food inside before heating.
- Microwave Use: Ensure the dish fits properly in your microwave and does not touch the sides or top during rotation.
- Cleaning: Allow dishes to cool before cleaning. Refer to the "Maintenance" section for detailed cleaning instructions.
- Lid Usage: The lid can be used in two positions: right-side up for covered cooking or inverted to act as a shallow baking dish or serving platter.
Setup
- Unpacking: Carefully remove all packaging materials from the casserole dishes and lids.
- Initial Cleaning: Before first use, wash both casserole dishes and their lids thoroughly with warm, soapy water. Rinse well and dry completely.

Operating Instructions
Oven Use
- Ultra Pro dishes are safe for use in conventional ovens up to 400°F (200°C).
- Always place food in the dish before placing it in a preheated oven.
- The lid can be used in two ways:
- Covered Cooking: Place the lid right-side up on the dish to retain moisture and steam.
- Roasting/Browning: Invert the lid and place it on top of the dish. This allows for browning while still providing some coverage, or the inverted lid can be used as a separate shallow baking dish.
- Always use oven mitts when removing hot dishes from the oven.
Microwave Use
- Ultra Pro dishes are safe for microwave use.
- Ensure the dish and lid fit comfortably inside your microwave and can rotate freely.
- When microwaving with the lid, ensure there is a small vent opening to allow steam to escape, or use the lid inverted.
- Always use caution when removing dishes from the microwave as contents and the dish itself can be very hot.
Freezer Use
- Ultra Pro dishes are freezer safe, allowing you to prepare meals in advance and freeze them.
- When transferring from freezer to oven, ensure the dish is not subjected to extreme thermal shock. It is recommended to allow the dish to temper slightly at room temperature before placing it in a preheated oven, or place it in a cold oven and then turn on the heat.

Maintenance and Cleaning
- Dishwasher Safe: The Ultra Pro Casserole Set is dishwasher safe. Place on the top rack for best results.
- Hand Washing: For hand washing, use warm, soapy water and a soft sponge or cloth. Avoid abrasive cleaners, scouring pads, or steel wool, as these can damage the surface.
- Stubborn Food Residue: If food is stuck, soak the dish in warm, soapy water for a period before cleaning. A plastic scraper can be used gently if needed.
- Drying: Ensure dishes are completely dry before storing to prevent water spots or odors.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Food sticking to the dish. | Insufficient greasing; high heat; food cooked too long. | Lightly grease the dish before adding food. Reduce cooking temperature or time. Soak the dish in warm, soapy water to loosen residue. |
| Dish appears discolored or stained. | Certain foods (e.g., tomato-based sauces) can cause staining over time. | This is typically cosmetic and does not affect performance. For minor stains, a paste of baking soda and water can sometimes help. Avoid harsh chemicals. |
| Dish warps or deforms. | Exceeded maximum temperature; direct heat source (stovetop/broiler). | Ensure oven temperature does not exceed 400°F (200°C). Never use on stovetop or under a broiler. If warping occurs, the dish may be permanently damaged. |
