Step‑by‑Step Instructions for Baked Salmon with Spinach
Step 1: Sauté Aromatics
Begin by heating a tablespoon of olive oil in a large skillet over medium heat. Add the sliced onions and sauté for 3-4 minutes until they become translucent and soft. Stir in the minced garlic and cook for an additional 30 seconds, allowing the garlic to become fragrant but not brown, creating a flavorful base for your Baked Salmon with Spinach.
Step 2: Add Spinach
Next, stir in the thawed, drained spinach into the skillet, cooking for 2-3 minutes until heated through. Season the mixture with salt and pepper to taste, then incorporate the sour cream until everything is creamy and well combined. This spinach mix will be a delicious topping for your salmon, ensuring it’s both creamy and nutritious.
Step 3: Prepare Salmon
Preheat your oven to 175°C (347°F) to prepare for baking. While the oven heats, season the salmon fillets generously with salt and pepper. Then, in a lightly oiled skillet, sear the salmon for about 2 minutes on each side over medium-high heat. Aim for a slightly raw center, ensuring it remains moist before the baking process infuses it with flavor.
Step 4: Assemble Dish
In a greased baking dish, place the seared salmon skin-side down. Generously top each fillet with the creamy spinach mixture, ensuring even coverage. Sprinkle a hearty amount of mozzarella cheese over the spinach to create a gooey crust as it bakes. This layering of flavors is essential for your delightful Baked Salmon with Spinach.
Step 5: Bake
Transfer the baking dish to the preheated oven and bake for 15-20 minutes. Keep an eye on the salmon, checking for doneness at around 63°C (145°F) — it should be opaque and flake easily with a fork. The cheese on top should turn a beautiful golden brown, signaling that your Baked Salmon with Spinach is ready to enjoy.
Step 6: Serve
Once fully baked, allow the dish to rest for a couple of minutes before serving. This resting phase ensures the salmon’s juices redistribute and the topping remains intact. Plate your beautiful Baked Salmon with Spinach, perhaps with a side of your favorite lighter dish, and enjoy the satisfying layers of flavor and texture!

Make Ahead Options
These delicious Baked Salmon with Spinach can be prepped ahead, making weeknight dinners a breeze! You can prepare the creamy spinach topping up to 24 hours in advance; simply sauté the onions and garlic, mix in the spinach and sour cream, and store in an airtight container in the refrigerator. This keeps the flavors fresh while reducing your cooking time. When you’re ready to enjoy this heart-healthy meal, simply sear the salmon, assemble it in a baking dish, and top with the prepped spinach mixture and mozzarella before baking. You’ll have restaurant-quality results with minimal effort!
