Step‑by‑Step Instructions for Baked Salmon with Spinach
Step 1: Sauté the Aromatics
Heat a skillet over medium heat and drizzle in olive oil. Once hot, add sliced onions, cooking them for 3-4 minutes until they turn translucent. Next, stir in minced garlic and sauté for an additional 30 seconds until fragrant, filling your kitchen with a lovely aroma that sets the stage for the Baked Salmon with Spinach.
Step 2: Add Spinach
Incorporate thawed spinach into the skillet with the onions and garlic. Sauté for 2-3 minutes, ensuring the spinach is heated through. Sprinkle with salt and pepper to taste, enhancing the flavors, and then mix in sour cream, stirring until the mixture is creamy and well combined, adding a luscious layer to your salmon dish.
Step 3: Prepare Salmon
Preheat your oven to 175°C (347°F). While it heats, season salmon fillets generously with salt and pepper. Sear each side of the fillets in a separate pan over medium heat for about 2 minutes, allowing them to develop a nice crust while locking in moisture—this is key for the perfect Baked Salmon with Spinach.
Step 4: Assemble Dish
In a greased baking dish, arrange the salmon fillets skin-side down. Spread the creamy spinach mixture generously over the top of each fillet, ensuring an even layer. Finish by sprinkling mozzarella cheese over the spinach layer, creating a delightful crust that will melt and bubble beautifully during baking.
Step 5: Bake
Carefully transfer the baking dish to the preheated oven and bake for 15-20 minutes. Keep an eye on your dish; it’s done when the salmon is opaque and flakes easily with a fork, and the cheese on top is golden and bubbly. This step transforms your ingredients into a comforting Baked Salmon with Spinach entrée.
Step 6: Serve and Enjoy
Once baked, let the dish rest for a few minutes to allow the flavors to meld. Then plate the salmon with a generous scoop of the creamy spinach mixture alongside it. This heart-healthy meal will dazzle your taste buds and your dinner guests alike, perfect for sharing or enjoying on your own!

Baked Salmon with Spinach Recipe FAQs
How do I choose the best salmon for this recipe?
When selecting salmon, look for fillets that have a vibrant pink color and a moist texture. Freshness is key—if possible, smell the salmon; it should have a mild, ocean-like scent rather than a strong fishy odor. I recommend visiting a trusted fishmonger’s for the best options!
What is the best way to store leftovers?
Store your Baked Salmon with Spinach in an airtight container in the fridge for up to 2 days. When reheating, gently warm it in the microwave or oven to avoid drying it out. If you’d like to keep the leftovers longer, freeze them for up to 3 months—just be sure to seal them tightly to prevent freezer burn.
Can I freeze the baked salmon? If so, how?
Absolutely! To freeze your Baked Salmon with Spinach, let it cool completely first. Then, wrap the dish tightly in plastic wrap, followed by aluminum foil to ensure it’s tightly sealed. Label with the date and store it in the freezer for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the fridge and reheat until warmed through.
What if I don’t have fresh spinach? Can I use frozen?
Yes! Frozen spinach is a fantastic alternative. Just make sure to thaw and thoroughly drain it to remove excess moisture before adding it to the sauté with onions and garlic. This will help maintain the creamy texture of the dish, avoiding any watery results!
Are there any dietary considerations I should keep in mind?
If you have dairy allergies, you can substitute the sour cream and mozzarella with non-dairy alternatives like cashew cream and plant-based cheese. And if you’re concerned about sodium intake, use low-sodium salt to adjust the flavor to your needs, ensuring everyone can enjoy this heart-healthy meal.
What can I do if my spinach mixture is too watery?
If your spinach mixture turns out too watery, try this—first, drain the mixture using a fine-mesh strainer to remove excess moisture. Next, return it to the skillet over medium heat and cook it for a few more minutes, stirring often, to evaporate any remaining liquid. Add more sour cream or cheese to thicken it up if needed. This way, your Baked Salmon with Spinach will have that delicious creamy consistency just right!
