Step-by-Step Instructions

Preheat Oven: Heat your oven to 425°F for even, fast baking.
Make the Butter Mixture: In a small bowl, whisk together melted butter, lemon juice, chopped garlic, thyme, paprika, and pepper. This infuses every bite with flavor.
Prep the Fish: Pat tilapia dry with paper towels. Season both sides with kosher salt. Arrange in a 9×13-inch baking dish – a slight overlap is fine. Use measuring cups and spoons set for precision.
Coat and Bake: Spoon the butter mixture evenly over the fillets. Bake 18-20 minutes until opaque and flaky. Check doneness with a fork.
Garnish and Serve: Sprinkle with fresh parsley. Squeeze lemon wedges over top. Spoon pan sauce over servings.

Total time: 25 minutes. Prep: 5 mins. Cook: 20 mins.

Helpful Tips for Perfect Results

Freshness First: Choose firm, mild tilapia for best texture. Pat dry to avoid watery results.
Flavor Boost: Add red pepper flakes for heat in dinner dishes, or extra lemon for tang.
Make-Ahead: Prep the butter mix up to 2 hours ahead; store in fridge.
Sides Pairing: Steam veggies in a steamer insert or roast on baking sheets.
Storage: Leftovers keep 2 days in airtight container. Reheat gently in oven.

Equip your kitchen with essentials like mixing bowls for easy mixing and kitchen utensils for serving.
