Step‑by‑Step Instructions for Baked Salmon with Spinach
Step 1: Sauté Aromatics
Heat a generous drizzle of olive oil in a skillet over medium heat. Add sliced onions and sauté for 3-4 minutes until they turn translucent, inviting their sweetness. Next, toss in minced garlic and sauté for an additional 30 seconds, stirring constantly until fragrant. This aromatic base will elevate the flavors of your Baked Salmon with Spinach.
Step 2: Add Spinach
Stir in the thawed and thoroughly drained spinach, cooking for 2-3 minutes until it’s warmed through and vibrant green. Season the mixture with salt and pepper to taste, then incorporate the sour cream for a creamy texture. This luscious spinach blend is the heart of your delicious dish, destined to lavishly cover the salmon.
Step 3: Prep Salmon
Preheat your oven to 175°C (347°F) as you prepare the salmon. Pat the salmon fillets dry and season them with salt and pepper on both sides. In a separate hot skillet, sear each fillet for about 2 minutes on medium heat until they’re lightly browned but still slightly raw in the center. This step captures moisture and flavor for your Baked Salmon with Spinach.
Step 4: Assemble Dish
Grease a baking dish with a touch of olive oil, then place the seared salmon fillets skin-side down. Generously layer the creamy spinach mixture over each fillet, ensuring each one is well-covered. Finally, sprinkle a good amount of mozzarella on top, setting the stage for a wonderfully cheesy crust.
Step 5: Bake
Carefully place the assembled dish in the preheated oven and bake for 15-20 minutes. Look for the cheese to bubble and turn golden, signaling it’s time for the dish to come out. The salmon should be opaque, with an internal temperature of 63°C (145°F) for perfectly cooked Baked Salmon with Spinach.
Step 6: Serve
Let the baked salmon rest for a few moments as you marvel at the bubbly, golden crust. When ready, serve the dish warm, pairing it with fresh sides like a salad or some creamy mashed potatoes. Your delightful Baked Salmon with Spinach is now ready to impress family and friends!
