“I made this on a hectic weeknight and my kids asked for seconds — creamy, cheesy, and fast. A keeper.” — home cook review
Reasons to try it:
- Quick assembly: about 10–15 minutes prep, 18–22 minutes in the oven depending on fillet thickness.
- Balanced: protein from salmon, iron-rich spinach, and moderate dairy for richness.
- Versatile: works with frozen spinach and common pantry staples.
- Crowd-pleaser: mild mozzarella keeps the flavor family-friendly.
The cooking process explained
Before you start: you’ll sauté onion, garlic, and drained thawed spinach to remove excess moisture and concentrate flavor. Fold that into sour cream, season, and spread over salmon fillets on a baking tray. Top with shredded mozzarella and bake until the salmon is flaky and the cheese is golden. Total hands-on time is low; most of the time is oven time.
What to expect while cooking:
- The spinach releases extra water when heated; sautéing then draining helps avoid a watery topping.
- Mozzarella gives a mild, creamy melt — if you want more browning, finish under the broiler for 1–2 minutes, watching closely.
- Salmon carries carry-over heat — it keeps cooking a little after you remove it from the oven, so pull it at just-done.
What you’ll need
- 2 fillets Salmon (Lachsfilet), about 150–200 g each (skin on or off as you prefer)
- Salt and Pepper (Salz und Pfeffer), to taste
- 300 g Spinach (Blattspinat), thawed and very well drained
- 1 Onion (Zwiebel), sliced thin
- 2 cloves Garlic (Knoblauch), minced
- 200 g Sour Cream (Sauerrahm) — or crème fraîche for tang
- 150 g Mozzarella, shredded or thinly sliced
- 1 tbsp Olive Oil (Olivenöl)
Quick notes and substitutions:
- If using fresh spinach, wilt ~150–200 g fresh in the pan until fully reduced (about 3–4 minutes) and squeeze out excess moisture.
- For dairy-free, swap sour cream with coconut yogurt and mozzarella with a plant-based melter.
- Lemon zest or a squeeze of lemon juice brightens the final dish — add before serving.
Step-by-step instructions
- Preheat the oven to 200°C (400°F). Line a baking tray with parchment or lightly oil it.
- Heat olive oil in a skillet over medium heat. Add sliced onion and cook 4–5 minutes until soft and translucent.
- Add minced garlic and cook 30 seconds until fragrant. Stir in the thawed, drained spinach. Cook 2–3 minutes to heat through and evaporate extra moisture. Season lightly with salt and pepper. Remove from heat.
- Transfer the spinach mixture to a bowl. Mix in sour cream and taste; adjust salt and pepper. If you like, add a pinch of nutmeg or lemon zest for depth.
- Pat the salmon fillets dry with paper towel. Season both sides with salt and pepper. Place fillets skin-side down on the prepared tray. Spread the spinach-sour cream mixture evenly over each fillet. Top with shredded or sliced mozzarella.
- Bake in the preheated oven for 12–18 minutes, depending on thickness. Salmon is done when it flakes easily and reaches an internal temperature of 63°C (145°F) at the thickest part. If you prefer a browned top, broil for 1–2 minutes at the end—watch closely to prevent burning.
- Rest the salmon 2–3 minutes before serving. Finish with a squeeze of lemon and a grind of fresh black pepper.
Ingredients
- 2 salmon fillets (approx. 300–400 g total)
- Salt and pepper, to taste
- 300 g thawed and thoroughly drained spinach
- 1 medium onion, sliced
- 2 garlic cloves, minced
- 200 g sour cream
- 150 g mozzarella, shredded or sliced
- 1 tbsp olive oil
Ingredient tips:
- Dry the thawed spinach by pressing it in a sieve or wrapping it in a kitchen towel and squeezing; this prevents a watery sauce.
- Use low-moisture mozzarella for less liquid; fresh mozzarella will release more water.
How to prepare it
This is the short process map:

Wine and beverage pairings:
- A zesty Sauvignon Blanc or a light Pinot Grigio cuts through the richness.
- For a non-alcoholic option, sparkling water with lemon or a cold iced green tea works well.
Storage and reheating tips
- Refrigerate: Store leftovers in an airtight container in the fridge for up to 2 days. Salmon softens and the topping may release liquid; gently reheat.
- Freeze: You can freeze cooked portions for up to 1 month. Thaw overnight in the fridge before reheating. Note: texture changes slightly after freezing.
- Reheating: Warm in a 160°C (325°F) oven for 8–12 minutes or until heated through. To keep the salmon moist, cover loosely with foil for the first part of reheating, then remove foil for the last 2–3 minutes to refresh the mozzarella. Avoid microwaving if possible—microwaves can make the fish rubbery.
Food safety note: Cooked seafood should not sit more than two hours at room temperature. When in doubt, refrigerate promptly.
Helpful cooking tips
- Pat salmon dry: removing surface moisture helps create a tasty exterior and prevents the topping from sliding off.
- Squeeze the spinach well: excess water waters down the sauce and lengthens bake time.
- Season in layers: a light seasoning on the spinach and another on the salmon ensures balanced flavor.
- Check doneness by temperature: 63°C/145°F is the safe internal temp; for a slightly tender result, remove at ~60–61°C and rest for carry-over cooking.
- Use a thin spatula to transfer baked fillets to plates to keep the topping intact.
Recipe variations
- Lemon-Herb: stir lemon zest and chopped dill into the sour cream for a fresher finish.
- Mediterranean: replace mozzarella with crumbled feta and add chopped sun-dried tomatoes and olives.
- Creamy Pesto: mix 2 tbsp pesto into the sour cream for a basil-forward twist.
- Low-dairy: substitute Greek yogurt for sour cream; choose a melty low-fat cheese or omit cheese and finish with panko for crunch.
- Spicy: add a pinch of chili flakes to the spinach mix or drizzle harissa before serving.
Common questions
Q: Can I use fresh spinach instead of frozen?
A: Yes. Use about 150–200 g fresh spinach and wilt it in the pan until fully reduced, then squeeze out excess moisture before mixing with sour cream.
Q: How do I know when the salmon is done?
A: The most reliable method is a meat thermometer at 63°C (145°F). Alternatively, check that flakes separate easily with a fork and the flesh is opaque.
Q: Can I assemble this ahead of time?
A: You can prepare the spinach-sour cream mixture a day ahead and keep it chilled. Assemble and add mozzarella just before baking for best texture. If assembled too early, the topping may release moisture.
Q: Is this recipe freezer-friendly?
A: Cooked portions freeze up to 1 month. Texture of the topping changes a bit on thawing; reheat gently to restore creaminess.
Q: What if my mozzarella gets watery?
A: Use low-moisture mozzarella or blot fresh mozzarella before topping. If it releases liquid while baking, drain any excess on the tray after baking and before serving.
Q: Can I use skin-on salmon?
A: Yes. Place fillets skin-side down; the skin helps hold the fillet together during baking and can be removed easily after cooking if you prefer.
