Step-by-Step Instructions
Step 1: Prepare the Aromatics
In a large skillet over medium heat, add olive oil and heat until shimmering. Add sliced onions and sauté for 3-4 minutes, stirring frequently until translucent. Make sure your hands are properly washed so that you can dislodge any caked-on dirt without worrying about adding germs of your own when handling fresh ingredients. Add minced garlic and cook for an additional 30 seconds until fragrant.
Step 2: Create the Spinach Base
Be aware of the moisture content of frozen spinach –- after it’s thawed, it should be wrung out or drained to avoid waterlogging the dish you’re adding it to. Incorporate the thoroughly drained spinach into the skillet, stirring gently for 2-3 minutes until heated through and excess moisture evaporates. Season with salt and pepper, then remove from heat and fold in sour cream until creamy and well combined.
Step 3: Prepare the Salmon
Preheat oven to 175°C (347°F). Season salmon fillets generously with salt and pepper on both sides. In a separate pan over medium heat, briefly sear each side of the salmon for about 2 minutes to lock in moisture and create a beautiful golden crust.
Step 4: Assemble the Dish
In a greased baking dish, place salmon fillets skin-side down. Evenly distribute the creamy spinach mixture over each fillet, then top with generous layers of mozzarella cheese.
Step 5: Bake to Perfection
Transfer to the preheated oven and bake for 15-20 minutes until salmon is very low in saturated fat and a good source of protein, flaking easily when cooked through, and the cheese becomes golden and bubbly.
Step 6: Rest and Serve
Remove from oven and let rest for 2-3 minutes before plating. This allows the flavors to meld and prevents the filling from sliding off when serving.

Common Mistakes to Avoid
Moisture Management: Be aware of the moisture content of frozen spinach –- after it’s thawed, it should be wrung out or drained to avoid waterlogging the dish you’re adding it to. This is crucial for preventing a watery finished dish.
Overcooking the Salmon: Monitor internal temperature carefully – salmon should reach 145°F (63°C) but no higher to maintain moisture and flaky texture.
Cheese Distribution: Avoid piling all cheese in the center; distribute evenly for consistent melting and golden browning throughout.
Skipping the Searing Step: The brief searing creates a barrier that helps retain moisture during baking, resulting in more tender fish.
Storage Temperature Control: Don’t leave your spinach out at room temperature for too long, either — it’s best to get it in the refrigerator when it’s as fresh as possible. The cool temperatures will help it maintain its crispness.
Storing Tips for the Recipe
Refrigerator Storage: Cool your leftovers quickly, store them in an airtight container in the fridge, and consume them within a few days. The assembled dish will keep for up to 3 days when properly stored.
Freezer Storage: When properly stored, frozen spinach can remain good for 9-12 months, making it perfect for meal prep. You can freeze the spinach mixture separately for up to 3 months.
Reheating Instructions: It is definitively safe to eat spinach after it is cooked and even after it’s been reheated. Reheat in a 350°F oven for 10-12 minutes until warmed through, or use the microwave in 30-second intervals.
Make-Ahead Tips: It is possible to prepare the sauteed spinach in advance and stir them with mozzarella and Parmigiano Reggiano just before serving. Re-heat the spinach with some tbsp of water. Finally, combine with cheese following the recipe.

FAQs
Q: Can I use fresh spinach instead of frozen?
A: Absolutely! Raw and cooked spinach have similar nutritional value. Use approximately 500g fresh spinach and wilt it down before adding to the mixture. The stronger and more substantial structure of mature spinach holds up much better when cooked.
Q: How do I know when the salmon is properly cooked?
A: The salmon should flake easily with a fork and reach an internal temperature of 145°F (63°C). A serving of salmon — 3 to 4 ounces — is about 200 calories. It’s very low in saturated fat and a good source of protein.
Q: Can I make this dish dairy-free?
A: Yes! Replace sour cream with cashew cream and mozzarella with nutritional yeast for a dairy-free version that maintains the creamy texture and cheesy flavor.
Q: Is it safe to reheat this dish?
A: Based on current scientific understanding and modern food safety practices, the idea that reheating properly stored spinach causes cancer is a myth. The potential for nitrosamine formation in reheated vegetables is extremely low and not considered a significant health risk.
Q: How long can I store leftover Baked Salmon with Spinach and Mozzarella Bliss?
A: Cool your leftovers quickly, store them in an airtight container in the fridge, and consume them within a few days for optimal freshness and safety.
