Step‑by‑Step Instructions for Baked Salmon with Spinach and Mozzarella Bliss
Step 1: Sauté Aromatics
In a skillet, heat 2 tablespoons of olive oil over medium heat. Add 1 diced onion and sauté for 3-4 minutes until it becomes translucent, releasing a fragrant aroma. Next, stir in 2 minced garlic cloves, cooking for an additional 30 seconds until they’re just fragrant but not browned.
Step 2: Add Spinach
To the aromatic mixture, stir in 4 cups of thawed and drained spinach. Cook for 2-3 minutes, allowing it to heat through while stirring gently. Season the spinach with salt and pepper to taste, and then mix in ½ cup of sour cream, creating a creamy, flavorful blend that will revive your senses.
Step 3: Prepare Salmon
Preheat your oven to 175°C (347°F) while you season 4 salmon fillets with salt and pepper on both sides. In a separate, hot skillet, sear the fillets for about 2 minutes on each side until they are golden brown but still slightly raw in the center. This helps keep the salmon moist during baking.
Step 4: Assemble Dish
Grease a baking dish with a touch of olive oil and place the salmon fillets skin-side down in the dish. Generously top each fillet with the creamy spinach mixture you just prepared. Finish by evenly sprinkling 1 cup of shredded mozzarella cheese over the top, ensuring each piece of salmon is well-covered.
Step 5: Bake
Transfer the assembled dish to your preheated oven and bake for 15-20 minutes. Look for the salmon to flake easily with a fork, and the mozzarella to be bubbly and golden brown on top. This visual cue signifies that your Baked Salmon with Spinach and Mozzarella Bliss is perfectly cooked.
Step 6: Serve
Once baked, remove the dish from the oven and let it rest briefly to allow the flavors to meld. Plate each piece of salmon with a generous portion of the creamy spinach mixture beside it. The warmth and inviting aroma will make your dining experience truly delightful.

Expert Tips for Baked Salmon Perfection
-
Searing Salmon: Ensure your skillet is hot enough when searing to get a beautiful crust without overcooking. This helps retain moisture in the salmon, making your Baked Salmon with Spinach and Mozzarella Bliss juicy and delightful.
-
Spinach Moisture: If using frozen spinach, make sure it’s thoroughly thawed and drained. Excess moisture can make the dish watery, so squeeze out any remaining water before mixing with the sour cream.

Baking Time: Keep an eye on your salmon while it bakes. Overbaking can dry it out; aim for just flaking easily and a bubbly golden cheese crust to get that perfect texture.
-
Temperature Check: Use a meat thermometer to ensure the internal temperature of the salmon reaches 63°C (145°F) for safe consumption. This will help you avoid the common mistake of under or overcooking.
-
Extra Seasoning: Don’t shy away from seasoning! Taste a bit of your spinach mixture before baking to adjust salt and pepper levels, ensuring your Baked Salmon with Spinach and Mozzarella Bliss is bursting with flavor.
