Baked Salmon with Spinach Ingredients
For the Salmon
- Salmon Fillet – The star of the show, fresh salmon offers a delicate flavor that’s rich in omega-3s and heart-healthy benefits.
- Salt and Pepper – Essential for enhancing the natural flavors; adjust these staples to suit your taste.
For the Spinach Mixture
- Spinach – Fresh or frozen spinach adds moisture and nutrition; make sure to drain frozen spinach thoroughly for the best consistency.
- Onion – Both yellow and white onions can be used to elevate the flavor of the spinach mixture through sautéing.
- Garlic – Fresh minced garlic provides a robust flavor; if you’re in a pinch, dried garlic can work in a hurry.
- Sour Cream – Brings a delightful creaminess to the dish; you can substitute with Greek yogurt for a healthier option.
For the Topping
- Mozzarella – This gooey cheese creates a delicious crust on top; consider Gouda for a distinctive taste.
- Olive Oil – Necessary for sautéing the onions and garlic, olive oil can be swapped for any neutral oil like canola or grapeseed if needed.
Step‑by‑Step Instructions for Baked Salmon with Spinach
Step 1: Sauté Aromatics
Begin by heating 1 tablespoon of olive oil in a skillet over medium heat. Once the oil shimmers, add 1 sliced onion and sauté for 3–4 minutes until they become translucent. Next, stir in 2 minced garlic cloves and cook for an additional 30 seconds, allowing the aroma to blossom. Remove the skillet from heat and set aside as you prepare the spinach.
Step 2: Add Spinach
In the same skillet, stir in 2 cups of thawed and drained spinach, cooking for 2–3 minutes until heated through. Season generously with salt and pepper to taste. To achieve a creamy consistency, mix in ½ cup of sour cream until the spinach is fully coated and luscious. This flavorful mixture is now ready to spread over the salmon.
Step 3: Prepare Salmon
Preheat your oven to 175°C (347°F) to ensure it’s just right for baking. While it heats up, season your fresh salmon fillet with salt and pepper on both sides. Heat a non-stick skillet over medium-high heat, sear the salmon skin-side down for about 2 minutes, until it’s a lovely golden brown, then carefully flip and sear the other side briefly—this step helps lock in moisture.
Step 4: Assemble Dish
Grease a baking dish lightly with olive oil and arrange the seared salmon skin-side down. Spoon the creamy spinach mixture over the top of the salmon, ensuring it’s evenly spread. To finish, generously sprinkle 1 cup of shredded mozzarella cheese over the spinach, creating a luscious heavenly layer that will melt into a delightful crust during baking.
Step 5: Bake
Transfer the baking dish to the preheated oven and bake for 15–20 minutes. Keep an eye on your dish until the salmon is opaque, and the mozzarella has turned golden and bubbly. The internal temperature of the salmon should reach 63°C (145°F) for perfect doneness—a meat thermometer can be helpful here!
Step 6: Serve
Once baked, remove the dish from the oven and let it rest for a few minutes. This helps the flavors settle beautifully. Serve the baked salmon on plates, spooning extra creamy spinach on the side to fully enjoy this heart-healthy dish.

Make Ahead Options
These Baked Salmon with Spinach and Mozzarella are perfect for busy weeknights, allowing you to enjoy a wholesome meal with minimal effort! You can prepare the creamy spinach mixture up to 24 hours in advance, storing it in an airtight container in the refrigerator to maintain its freshness. Additionally, season and sear the salmon fillets a few hours ahead of time for added convenience; just be sure to keep them covered in the fridge. When you’re ready to enjoy, simply assemble the dish by placing the seared salmon in a greased baking dish, spreading the spinach mixture over the top, and sprinkling the mozzarella cheese before baking. This way, you’ll have a delicious, heart-healthy dinner ready in no time!
