Instructions
1
Pat salmon fillets dry with paper towels and season evenly with salt and black pepper on both sides.
2
Heat olive oil in a large skillet over medium heat. Place salmon skin-side down and sear for 5 minutes, then carefully flip and cook an additional 4 to 5 minutes until golden and just cooked through. Remove fillets from skillet and set aside.
3
Reduce heat to medium-low. Add unsalted butter to the same skillet; once melted, incorporate minced garlic and chopped onion. Sauté for 2 to 3 minutes until soft and fragrant.
4
Pour chicken broth into the skillet, using a spatula to scrape up any browned bits from the bottom.
5
Stir in heavy cream and Italian seasoning, mixing well. Let the sauce simmer gently for 2 to 3 minutes until it begins to thicken.
6
Add baby spinach to the skillet and cook for 2 to 3 minutes, stirring frequently, until the spinach wilts into the sauce.
7
Return seared salmon fillets to the skillet. Spoon the creamy sauce generously over each portion and simmer for a final 2 minutes to heat salmon through. Serve immediately.
Essential Tips
Room temperature salmon
Let salmon sit at room temperature for 15 minutes before cooking to ensure even cooking throughout the fillet. Cold salmon straight from the fridge will cook unevenly, with a raw center and overcooked edges.
Butter temperature control
Remove butter from heat source just before it's fully melted to prevent overcooking before the garlic goes in. The residual heat will melt it perfectly while keeping the garlic from burning.
Sauce consistency check
The cream sauce should coat the back of a spoon lightly when done. If it's too thin, simmer longer; if too thick, add a splash of broth. The sauce will continue to thicken slightly as it sits.
Spinach timing
Add spinach only after the sauce has thickened slightly, just before you return the salmon. This preserves its vibrant color and prevents it from turning gray in the simmering sauce.
Low and slow simmer
Maintain a gentle simmer rather than a rolling boil when cooking the salmon in the sauce. This prevents the cream from curdling and keeps the fish tender rather than rubbery.
Smart Swaps & Variations
Lighter version
Swap heavy cream for half-and-half or whole milk mixed with 2 tablespoons of cornstarch to maintain body while reducing fat content.
Dairy-free
Use coconut milk and dairy-free butter substitute, adding a pinch of xanthan gum to help the sauce thicken properly.
Herb variation
Replace Italian seasoning with fresh basil, thyme, and a squeeze of lemon juice for a brighter, spring-inspired flavor profile.
Mushroom addition
Sauté sliced cremini mushrooms with the onions for an earthy depth that complements the salmon beautifully.
What to Serve With This
- Creamy mashed potatoes to soak up the garlic butter sauce
- Toasted crusty bread or garlic bread for serving alongside
- Steamed asparagus or roasted Brussels sprouts for a vegetable side
- Chilled pinot grigio or chardonnay to complement the rich sauce
Storage & Reheating
Storage
Store leftovers in an airtight container in the refrigerator for up to 2 days. The salmon and sauce will keep their integrity but may thicken slightly upon cooling.
Reheating
Reheat gently in a skillet over low heat with a splash of broth or water to loosen the sauce. Microwaving is not recommended as it can make the salmon dry and the sauce split.
Expert Chef Tips
- Use the residual heat from the salmon to cook the sauce after removing the fish from the pan. The hot fillets will gently warm the sauce without overcooking it.
- Add a pat of cold butter at the end to give the sauce a glossy, restaurant-quality finish. Whisk vigorously to emulsify for a velvety texture.
- For perfectly even cooking, choose salmon fillets of uniform thickness. If needed, fold thinner edges under before seasoning to prevent overcooking.
Equipment You’ll Need
- Large stainless steel or cast iron skillet (12-inch minimum)

Frequently Asked Questions
Can I use frozen salmon for this recipe?
Yes, you can use frozen salmon, but thaw it completely in the refrigerator overnight first. Pat it very dry before cooking to ensure proper searing. Frozen salmon may release more moisture during cooking, so you might need to simmer the sauce a bit longer to achieve the right consistency.
What's the best way to avoid overcooking the salmon?
Start checking the salmon at the 4-minute mark when flipping. The fish is done when it reaches 125°F internally and flakes easily with a fork. Remove it from the heat just before it reaches your desired doneness, as it will continue cooking in the residual heat of the sauce.
Can I make this ahead for dinner guests?
You can prepare all components up to step 5 (before adding spinach) up to 4 hours ahead. Store the sauce and cooked salmon separately in the refrigerator, then gently reheat the sauce and salmon together when ready to serve. Add spinach fresh just before serving.
What's a good substitute for heavy cream?
For a lighter option, use half-and-half or whole milk thickened with 2 tablespoons of cornstarch. For a dairy-free version, coconut milk works well, though the flavor will be slightly different. Greek yogurt can also work but may cause slight curdling if boiled.
Why is my sauce grainy or split?
A grainy sauce typically results from the butter or cream being too cold when added to the hot pan. To fix a split sauce, remove from heat and whisk in a tablespoon of ice water or additional warm broth to re-emulsify. Never boil the sauce vigorously as this can cause separation.
Can I use skinless salmon fillets?
Absolutely, though the skin helps hold the fillet together during searing. If using skinless, be extra gentle when flipping and consider using a fish spatula to lift the delicate flesh. You may need to reduce the searing time by 1-2 minutes per side.
What wine pairs best with this dish?
A crisp white wine like Sauvignon Blanc or Pinot Grigio complements the rich cream and garlic flavors beautifully. For red wine lovers, a light-bodied Pinot Noir works well. Avoid heavy oaked Chardonnays as they can overpower the delicate salmon flavor.
How do I know when the sauce is properly thickened?
The sauce should coat the back of a spoon lightly when done. It should hold a line when you draw a finger through it on the spoon's surface. If it runs back together too quickly, it needs more simmering. If it's too thick, thin it with a splash of warm broth.
