Step‑by‑Step Instructions for Baked Salmon with Spinach
Step 1: Sauté Aromatics
Heat 2 tablespoons of olive oil in a skillet over medium heat. Add 1 sliced onion, sautéing until it’s translucent and soft, about 3-4 minutes. Stir in 2 minced garlic cloves, cooking until fragrant, roughly 30 seconds. This aromatic base sets the stage for the creamy spinach mixture in your Baked Salmon with Spinach.
Step 2: Add Spinach Mixture
Once the garlic has released its aroma, gently stir in thawed and drained spinach. Cook this mixture for 2-3 minutes until it’s heated through, mixing in salt and pepper to taste. Finally, fold in ½ cup of sour cream for a delightful creamy texture, creating a luscious layer that will complement the salmon perfectly.
Step 3: Prepare Salmon
Preheat your oven to 175°C (347°F) while you season the salmon fillets with salt and pepper on both sides. In the same skillet, quickly sear each side of the fillets for about 2 minutes to lock in moisture. This initial sear ensures your Baked Salmon with Spinach will remain juicy and flavorful right through to the last bite.
Step 4: Assemble Dish
Grease a baking dish lightly with olive oil and place the seared salmon skin-side down. Generously spoon the creamy spinach mixture over each fillet, ensuring even coverage. Finish by sprinkling grated mozzarella cheese on top. This assembly will create a delightful crust as it bakes, enhancing the overall flavor of the dish.
Step 5: Bake
Transfer the assembled dish into your preheated oven and bake for 15-20 minutes. Keep an eye out for the salmon to turn opaque and easily flake with a fork, indicating it’s done. For safety, check that the internal temperature reaches 63°C (145°F). The heavenly aroma will fill your kitchen, letting you know that your heart-healthy dinner is almost ready!
Step 6: Serve
After removing the dish from the oven, let the salmon rest for a few minutes to retain its juices. Consider garnishing with fresh herbs like parsley or dill for an extra pop of flavor. Your Baked Salmon with Spinach is now ready to be served, providing a comforting and nutritious meal that your family will thoroughly enjoy.
