Ingredients

• 680g (1.5 lbs / 4 fillets) salmon fillets, skin-on
• 113g (4 oz / 8 tbsp) unsalted butter
• 300g (10.5 oz / 10 cups) fresh baby spinach
• 120ml (4 fl oz / 1/2 cup) heavy cream
• 6 garlic cloves, minced
• 60ml (2 fl oz / 1/4 cup) dry white wine
• 30g (1 oz / 1/3 cup) grated Parmesan cheese
• 30ml (1 fl oz / 2 tbsp) extra virgin olive oil
• 15ml (0.5 fl oz / 1 tbsp) fresh lemon juice
• 5g (0.2 oz / 1 tsp) sea salt
• 2g (0.07 oz / 1/2 tsp) black pepper
• 1g (0.04 oz / 1/4 tsp) red pepper flakes
• 15g (0.5 oz / 2 tbsp) fresh parsley, chopped

Instructions

1. Step 1: Remove salmon from refrigerator 15 minutes before cooking to bring to room temperature. Pat fillets dry with paper towels and season both sides generously with sea salt and black pepper.
2. Step 2: Heat olive oil in a large cast-iron or heavy-bottomed skillet over medium-high heat until shimmering but not smoking.
3. Step 3: Place salmon fillets skin-side up in the pan and sear for 4-5 minutes without moving them, until a golden crust forms on the bottom.
4. Step 4: Carefully flip salmon fillets using a thin spatula and cook for another 3-4 minutes for medium doneness. Remove salmon to a plate and tent with foil to keep warm.
5. Step 5: Reduce heat to medium and add 56g (2 oz / 4 tbsp) butter to the same pan. Once melted, add minced garlic and red pepper flakes, cooking for 30 seconds until fragrant.
6. Step 6: Pour in white wine to deglaze the pan, scraping up any browned bits with a wooden spoon. Let wine reduce by half, about 2 minutes.
7. Step 7: Add heavy cream to the pan and simmer for 2 minutes until slightly thickened, stirring occasionally.
8. Step 8: Add baby spinach in batches, stirring until wilted. This will take about 2-3 minutes total.
9. Step 9: Remove pan from heat and stir in remaining 57g (2 oz / 4 tbsp) butter, Parmesan cheese, and lemon juice until butter is melted and sauce is glossy.
10. Step 10: Taste and adjust seasoning with additional salt and pepper if needed.
11. Step 11: Return salmon fillets to the pan, nestling them into the creamy spinach mixture.
12. Step 12: Garnish with fresh chopped parsley and serve immediately while hot.

Chef’s Tips

• For perfect salmon doneness, aim for an internal temperature of 145°F (63°C) using an instant-read thermometer inserted into the thickest part of the fillet.
• Don’t overcrowd the pan when searing salmon – cook in batches if necessary to ensure proper browning and avoid steaming the fish.
• Save pasta water concept: Reserve some of the garlic butter sauce before adding spinach to drizzle over the finished dish for extra richness and flavor.

Health Benefits

This nutrient-dense recipe provides exceptional health benefits for those following a ketogenic lifestyle. Salmon delivers high-quality complete protein and omega-3 fatty acids EPA and DHA, which support brain health, reduce inflammation, and promote cardiovascular wellness. The spinach contributes folate, iron, and powerful antioxidants like lutein and zeaxanthin for eye health. The high fat content from butter and cream helps with satiety and supports ketosis, while keeping net carbs minimal to maintain your metabolic state.

Storage Instructions

Store leftover salmon and spinach in an airtight container in the refrigerator for up to 3 days. Reheat gently in a low oven at 275°F (135°C) for 8-10 minutes to prevent overcooking. The cream sauce may separate slightly when reheated – simply stir in a tablespoon of fresh cream to restore consistency. Not recommended for freezing as the texture of both the fish and cream sauce will be compromised.
