Step‑by‑Step Instructions for Baked Salmon with Spinach
Step 1: Sauté Aromatics
Begin by heating 1 tablespoon of olive oil in a skillet over medium heat. Add 1 finely sliced onion and sauté for about 3-4 minutes until translucent, stirring occasionally. Next, introduce 2 minced garlic cloves and stir for another 30 seconds until fragrant, filling your kitchen with a warm aroma that perfectly complements the Baked Salmon with Spinach dish.
Step 2: Prepare Spinach Mixture
Stir in 2 cups of thawed and drained spinach, mixing it with the sautéed onions for about 2-3 minutes until heated through. Once warmed, season the mixture with salt and pepper to taste, then blend in ½ cup of sour cream until the mixture is smooth and creamy, creating a delicious base for the salmon.
Step 3: Prepare Salmon
While the spinach mixture cools slightly, preheat your oven to 175°C (347°F). Take your salmon fillets, about 4-6 ounces each, and season them generously with salt and pepper. In a separate pan, sear each side of the fillets for around 2 minutes on medium-high heat, ensuring a golden crust that locks in moisture and flavor before baking.
Step 4: Assemble Dish
Grease a baking dish with a touch of olive oil to prevent sticking. Arrange the seared salmon fillets skin-side down in the dish. Carefully top each fillet with the creamy spinach mixture, spreading it evenly. Finally, sprinkle 1 cup of shredded mozzarella cheese over the spinach, setting the stage for a beautiful baked result.
Step 5: Bake
Place the assembled dish in the preheated oven and bake for 15-20 minutes. The Baked Salmon with Spinach is ready when the salmon becomes opaque and flakes easily with a fork. Ensure that the cheese is golden and bubbly, while the internal temperature of the salmon reaches 63°C (145°F) for optimal doneness.
Step 6: Serve
Once baked, remove the dish from the oven and let it rest for about 5 minutes to allow the flavors to meld. Carefully plate the salmon and spinach combo, showcasing its creamy, cheesy top. Your delicious Baked Salmon with Spinach is now ready to be enjoyed—savor every bite!
