🛒 Ingredients
4 fish fillets (such as cod, tilapia, or haddock), skinless
Salt and pepper, to taste
2 tbsp olive oil or avocado oil
3 tbsp unsalted butter
2 cloves garlic, minced
1 lemon, juiced and zested
1 tsp dried parsley or 1 tbsp fresh parsley, chopped
Optional: lemon slices for garnish
👩🍳 Instructions
1. Prepare the Fish
Pat the fish fillets dry with a paper towel. Season both sides with salt and pepper.
2. Sear the Fillets
Heat olive oil in a large skillet over medium-high heat. Add the fish and cook for 3–4 minutes per side, or until golden brown and cooked through. Remove the fillets and set aside.
3. Make the Lemon Butter Sauce
In the same skillet, reduce heat to medium. Add butter and garlic, sautéing for 1 minute until fragrant. Stir in lemon juice, lemon zest, and parsley. Cook for another 1–2 minutes, allowing the sauce to thicken slightly.
4. Combine and Serve
Return the fish fillets to the skillet, spooning the lemon butter sauce over them. Serve immediately with optional lemon slices for garnish.
🍽️ Serving Suggestions
Serve with sautéed zucchini noodles or steamed asparagus for a low-carb meal.
Pair with cauliflower rice or a fresh green salad for a complete keto-friendly dinner.
Drizzle extra lemon butter sauce on the side for maximum flavor.
🧊 Storage Tips
Refrigerate: Store leftovers in an airtight container for up to 2 days.
Reheat: Warm gently in a skillet over low heat to avoid drying out the fish.
🔥 Pro Tips
Choose firm, flaky fish like cod or tilapia to prevent breaking during cooking.
Don’t overcook — fish cooks quickly and can become dry if left too long.
Add a pinch of red pepper flakes to the sauce for a subtle kick.
