Based on the microwave-safe container shown in the photo:
Remove Lid: Remove the lid completely before heating. (Do not microwave with the lid sealed or partially on).
Add Moisture: Sprinkle 1 teaspoon of water evenly over the noodles. This creates steam to re-soften the noodles without making them soggy.
Microwave: Heat uncovered on HIGH for 1.5 to 2 minutes (based on an 800W–1000W microwave).
Cover & Rest: Carefully remove from the microwave (it will be hot), cover loosely with the lid (or a paper towel), and let it sit for 30 seconds. This traps the steam to finish heating the shrimp through.
Toss & Serve: Remove the cover, toss gently with a fork to distribute the heat and sauce, and serve.
Pro Tip: If reheating from frozen, thaw overnight in the fridge first, or add 1 minute to the heating time and stir halfway through.
