Equipment

Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 190°C. Line a baking dish with parchment paper for easy cleanup. Take the salmon fillets out of the refrigerator 15 minutes before cooking to bring them closer to room temperature, which promotes more even cooking.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In a small bowl, prepare the lemon butter mixture by combining the softened butter, lemon juice, lemon zest, minced garlic, chopped dill, parsley, salt, pepper, and red pepper flakes if using. Mix thoroughly until all ingredients are well incorporated. The softened butter will easily absorb the flavors of herbs and citrus, creating a more aromatic sauce.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Pat the salmon fillets dry with paper towels. This important step removes excess moisture, allowing the salmon to cook properly rather than steam, and helps the butter mixture adhere better to the surface.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Place the salmon fillets skin-side down on the prepared baking dish. The skin creates a natural barrier between the heat and the delicate flesh, helping to prevent overcooking.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Using a spoon or spatula, generously spread the lemon butter mixture over each salmon fillet, ensuring they're completely covered. Leave some extra butter on top as it will melt during baking, creating a luscious sauce that will baste the salmon as it cooks.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Arrange lemon slices around and slightly on top of the salmon fillets for additional flavor and a beautiful presentation. The lemon slices will release their oils during baking, adding another layer of citrus aroma.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Bake in the preheated oven for 12-15 minutes, or until the salmon reaches an internal temperature of 63°C on a kitchen thermometer. The cooking time may vary slightly depending on the thickness of your fillets. The salmon should flake easily with a fork but still maintain a moist, slightly translucent center - this is the sweet spot for perfectly cooked salmon that remains juicy.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Once done, let the salmon rest for 3 minutes before serving. This allows the juices to redistribute throughout the fish, ensuring maximum flavor and moisture. Spoon any melted butter sauce from the baking dish over the top of the fillets.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Garnish with additional fresh dill and serve immediately. For a complete keto meal, pair with steamed asparagus, broccoli, or a fresh green salad dressed with olive oil and lemon juice. Enjoy this delicious, keto-friendly dinner that's low in carbs but high in flavor!</li></ol>

How to cook Keto Lemon Butter Baked Salmon Recipe at home?

Learn how to cook Keto Lemon Butter Baked Salmon by preheating your oven to 190°C, making a butter mixture with lemon, herbs and garlic, patting salmon fillets dry, placing them skin-side down on a parchment-lined baking dish, covering with the butter mixture and baking for 12-15 minutes until they reach an internal temperature of 63°C.

How do you know when baked salmon is perfectly cooked?

Perfectly cooked salmon should reach an internal temperature of 63°C when measured with a kitchen thermometer. It should flake easily with a fork while still maintaining a slightly translucent, moist centre. Avoid overcooking as this will dry out the fish and diminish its delicate flavour.

Can I use frozen salmon fillets for this lemon butter recipe?

Yes, you can use frozen salmon fillets, but ensure they're completely thawed before cooking. Pat them thoroughly dry to remove excess moisture, which is crucial for proper caramelisation and to prevent steaming. Thawed salmon may release more liquid during cooking, so adjust baking time accordingly.

What are the best low-carb side dishes to serve with baked salmon?

Excellent keto-friendly sides include roasted asparagus, sautéed spinach with garlic, cauliflower rice, a crisp green salad with olive oil dressing, steamed broccoli, or roasted Brussels sprouts. These vegetables complement the rich buttery salmon while maintaining a low-carb profile.
