Step‑by‑Step Instructions for Irresistible Baked Salmon with Spinach
Step 1: Sauté Aromatics
In a medium skillet, heat 2 tablespoons of olive oil over medium heat. Once the oil is shimmering, add 1 sliced onion and sauté until translucent, about 3-4 minutes. Add 2 minced garlic cloves and cook for an additional 30 seconds until fragrant, making sure not to let the garlic brown. The aroma will fill your kitchen, signaling the perfect start to your Irresistible Baked Salmon with Spinach.
Step 2: Add Spinach
Stir in 2 cups of thawed, well-drained spinach into the skillet with the onions and garlic. Cook for about 2-3 minutes, ensuring all excess moisture evaporates. Season generously with salt and pepper to taste, then mix in ½ cup of sour cream until well combined. This creamy spinach mixture will serve as a luscious topping, bringing together delightful flavors.
Step 3: Prepare Salmon
Preheat your oven to 175°C (347°F). While it heats, season two fresh salmon fillets with salt and pepper on both sides. In a separate skillet, sear the salmon over medium-high heat for about 2 minutes on each side, allowing the center to remain slightly undercooked. This step helps lock in moisture, ensuring a tender result in your baked salmon.
Step 4: Assemble Dish
Once the spinach mixture and salmon are ready, take a greased baking dish and carefully arrange the seared salmon fillets at the bottom. Spoon the creamy spinach mixture evenly over the fillets, ensuring a generous layer. Top everything with 1 cup of shredded mozzarella cheese to create that irresistible bubbly crust.
Step 5: Bake
Place the assembled dish into the preheated oven, baking for 15-20 minutes. Keep an eye on it; the salmon should flake easily with a fork, and the cheese should be golden and bubbly. You can use a meat thermometer to ensure the salmon reaches an internal temperature of 63°C (145°F) for perfect doneness.
Step 6: Serve
After removing the dish from the oven, let the salmon rest for a couple of minutes. This pause allows the juices to redistribute, enhancing the overall flavor. Serve your Irresistible Baked Salmon with Spinach alongside your favorite sides, like roasted asparagus or a light salad, to create a wholesome and satisfying meal at home.

Make Ahead Options
These Irresistible Baked Salmon with Spinach are perfect for meal prep, allowing you to enjoy healthy home cooking even on the busiest nights! You can prepare the creamy spinach mixture up to 24 hours in advance; simply refrigerate it in an airtight container to maintain its freshness. Additionally, the salmon can be seasoned and even seared ahead of time, keeping it ready to pop in the oven. When you’re ready to serve, layer the spinach on the salmon, sprinkle with mozzarella, and bake as directed. This way, you’ll serve a delicious, restaurant-quality meal with minimal effort, making busy weeknights a breeze!
