Ingredients

  • 1 lb. fillet of fish
  • 1 stick butter, softened
  • 1/2 tsp. parsley
  • 2 Tbsp. lemon juice
  • 1/2 c. crushed Ritz cracker crumbs

Instructions

  3. Cover loosely with plastic wrap.

Tips & Substitutions

For an extra layer of flavor, consider adding garlic powder or paprika to the Ritz cracker topping. If you don’t have Ritz crackers, any buttery cracker or panko breadcrumbs can work well as a substitute. For a healthier version, swap butter for olive oil and use fresh herbs like dill instead of parsley. Always ensure your fish is evenly coated for the best flavor.

Serving Suggestions

Serve the Buttery Crunchy Microwave Fish Fillets over a bed of rice or alongside a fresh green salad for a complete meal.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place the fish in the microwave for 1-2 minutes, covered, to maintain moisture. Alternatively, you can reheat it in a preheated oven at 350°F for about 10 minutes until warmed through, which helps keep the cracker topping crisp.

Frequently Asked Questions

Can I use frozen fish fillets for this recipe?

Yes, you can use frozen fish fillets, but make sure to thaw them completely before cooking. Thawing ensures even cooking and helps the butter and seasonings adhere better. Microwave the fish on a defrost setting first if needed, then proceed with the recipe as instructed.

What type of fish works best for this dish?

Mild-flavored fish like tilapia, cod, or haddock work best for this recipe, as they absorb the buttery flavor well. However, feel free to experiment with your favorite fish fillets. Just adjust the cooking time based on the thickness of the fillets to ensure they are cooked through.

Can I make this recipe without a microwave?

Absolutely! If you prefer not to use a microwave, you can bake the fish in a preheated oven at 375°F for about 15-20 minutes, or until the fish flakes easily with a fork. Cover the dish with foil to keep it moist, and remove the foil for the last few minutes to crisp up the cracker topping.
