🛒 Ingredients

For the Fish

• 4 fish fillets (tilapia, cod, halibut, haddock, or your favorite white fish), about 5–6 oz each
• ½ tsp salt
• ½ tsp black pepper
• 1 tsp garlic powder
• ½ tsp paprika
• ½ tsp onion powder
• 1 tbsp olive oil

For the Zesty Lemon Butter Sauce

• 2 tbsp unsalted butter
• 3 cloves garlic, finely minced
• ¼ cup fresh lemon juice
• 1 tsp lemon zest
• ¼ cup low-sodium chicken or vegetable broth
• ½ tsp Italian seasoning
• ¼ tsp red pepper flakes, optional
• 2 tbsp chopped fresh parsley
• Salt and black pepper, to taste

👩‍🍳 Instructions

1. Prepare the Fish

Pat the fish fillets completely dry with paper towels. This helps them brown nicely instead of steaming.

Season both sides with salt, black pepper, garlic powder, paprika, and onion powder.

2. Sear the Fish

Heat the olive oil in a large nonstick or stainless-steel skillet over medium-high heat.

Place the fish in the hot skillet and cook for approximately 3–4 minutes per side, depending on thickness.

The fish should be golden on the outside and opaque and flaky in the center. Transfer the cooked fillets to a plate.

3. Make the Lemon Butter Sauce

Reduce the heat to medium.

Add the butter to the same skillet. Once melted, add the minced garlic and sauté for about 30–60 seconds, just until fragrant.

Pour in the lemon juice and broth. Add the lemon zest, Italian seasoning, and red pepper flakes.

Let the sauce gently simmer for 2–3 minutes, allowing it to reduce slightly.

4. Finish the Fish

Return the fish fillets to the skillet.

Spoon the lemon butter sauce over the fish and let everything simmer gently for 1–2 minutes.

Remove from the heat and sprinkle with fresh parsley.
