Baked Salmon with Spinach Ingredients
For the Salmon
• Salmon Fillet – The star protein providing heart-healthy omega-3s; opt for bright pink fillets for a rich flavor.
• Salt and Pepper – Essential for enhancing the natural taste; adjust to your preference for seasoning.
For the Spinach Mixture
• Spinach – Adds moisture and vital nutrients; frozen spinach is a convenient alternative when fresh isn’t available.
• Onion – Elevates the flavor of the dish; both yellow and white onions work beautifully.
• Garlic – Fresh is best for maximum flavor impact; dried garlic can be used in a substitute pinch.
• Sour Cream – Contributes creaminess to the spinach mixture; Greek yogurt can serve as a lighter substitute.
For the Crust
• Mozzarella Cheese – Creates a delightful, golden crust on top; Gouda can offer a richer flavor profile for a tasty variation.
• Olive Oil – Used for sautéing the onion and garlic; canola or grapeseed oil can be alternatives if needed.
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 sliced onions and sauté for 3-4 minutes until they become translucent and fragrant. Then, incorporate minced garlic, stirring for another 30 seconds until it’s golden and aromatic. This mixture lays the flavor foundation for your Baked Salmon with Spinach.
Step 2: Prepare Spinach Mixture
Stir in thawed and well-drained frozen spinach into the skillet, continuing to heat through for 2-3 minutes. Season generously with salt and pepper to taste, mixing well. Finally, add 1/3 cup of sour cream, ensuring it’s evenly distributed within the spinach. This creamy mixture is the perfect topping for your salmon.
Step 3: Prepare Salmon
Preheat your oven to 175°C (347°F). While the oven is heating, season the salmon fillets with salt and pepper on both sides. In the same skillet, sear each fillet skin-side down for about 2 minutes, allowing them to lock in moisture and flavor. You’ll know they’re ready for baking when they develop a slight golden crust.
Step 4: Assemble Dish
Lightly grease a baking dish with olive oil. Place the seared salmon skin-side down in the dish, and spoon the creamy spinach mixture generously over the top of each fillet. Sprinkle a generous amount of shredded mozzarella cheese evenly over the spinach layer, creating a luscious crust that will bake beautifully.
Step 5: Bake
Transfer the assembled dish to the preheated oven and bake for 15-20 minutes. Keep an eye on the salmon; it should turn opaque and flake easily when done. The cheese should bubble and become golden brown, indicating the dish is ready. For perfect results, check that the internal temperature of the salmon reaches 63°C (145°F).
Step 6: Serve
Once baked, remove the dish from the oven and allow it to rest for a few minutes before serving. This will help the flavors settle. For an added touch, garnish your Baked Salmon with Spinach and Mozzarella Crust with fresh herbs, if desired, for a pop of color and fresh flavor.
