Step‑by‑Step Instructions for Baked Salmon with Spinach and Mozzarella Bliss
Step 1: Sauté Aromatics
Begin by heating 2 tablespoons of olive oil in a skillet over medium heat. Add 1 sliced onion to the hot oil and sauté for 3-4 minutes until the onions become translucent and fragrant. Then, toss in 2 minced garlic cloves, stirring constantly for about 30 seconds until they’re aromatic and golden.
Step 2: Add Spinach
Next, incorporate 3 cups of thawed and well-drained spinach into the skillet with the sautéed onions and garlic. Stir continuously for 2-3 minutes, allowing the spinach to heat through and the moisture to evaporate. Season the spinach mix with salt and pepper to taste, then stir in ½ cup of sour cream until everything is combined and creamy.
Step 3: Prepare Salmon
Preheat your oven to 175°C (347°F) to ensure it’s ready for baking. While the oven warms up, take your salmon fillet and pat it dry with a paper towel. Season both sides generously with salt and pepper. In a separate skillet, sear the salmon fillet in olive oil over medium-high heat, cooking for 2 minutes on each side until it develops a light golden crust while remaining slightly undercooked.
Step 4: Assemble Dish
In a greased baking dish, carefully place the seared salmon fillet skin-side down. Spread the creamy spinach mixture evenly over the top of the salmon, ensuring it’s well-coated. Finally, sprinkle a generous portion of mozzarella cheese over the spinach layer, covering it completely for that lovely gooey texture.
Step 5: Bake
Place the assembled dish in the preheated oven and bake for 15-20 minutes. Keep an eye on the salmon; it’s done when it’s opaque and flakes easily with a fork, while the cheese is bubbling and beautifully golden on top—this is the visual cue for perfect baked salmon with spinach and mozzarella bliss.
Step 6: Serve
After baking, remove the dish from the oven and let it rest for a couple of minutes to allow the flavors to meld. Serve your Baked Salmon with Spinach and Mozzarella Bliss alongside the remaining creamy spinach, creating a comforting and delightful meal that everyone will cherish!
