Things You'll Need
4 fresh or thawed fish fillets
Microwave-safe 12-by-8-by-2-inch baking dish
Melted butter
Pastry brush
Seasonings, such as lemon pepper and garlic, to taste
Heavy-duty microwavable plastic wrap
Toothpick

When you're short on time but don't want to sacrifice a healthy meal, use your microwave to create a dinner party-worthy fish dish. Fish cooked in a microwave retains all of its natural flavor, but is easier to prepare than many other cooking methods. Serve the fish alongside a fresh salad or microwaved vegetables to complete the fast meal.
Step 1
Arrange four fresh or thawed fish fillets, such as catfish, flounder or salmon, in a 12-by-8-by-2-inch microwave-safe baking dish. Place the thicker pieces of fish along the edges of the dish, where they will cook faster.
Step 2
Cover the tops of the fillets with 2 tbsp. melted butter using a pastry brush, which will help keep the fillets moist during the cooking process.
Step 3
Season the buttered fish to taste. Sprinkle salt, pepper, lemon pepper, garlic or onion powder or dried parsley or chives over the fillets. Add minced ginger and garlic, along with a splash or sesame oil and soy sauce, to give the dish an Asian flair. Squeeze the juice of 1/2 of a lemon onto the fillets for a fresh, citrus flavor.
Step 4
Cover the dish tightly with a piece of heavy-duty, microwavable plastic wrap. Poke a few small holes in the top of the wrap using a toothpick so steam can escape.
Step 5
Place the dish in the microwave and cook it at medium-high for 4 1/2 minutes. Take the dish out of the microwave and rearrange the fish to ensure even cooking. Re-cover the dish and microwave the fish for another 4 1/2 minutes, or until the fish becomes opaque.
