Why You'll Love This Recipe
About the Ingredients
4 (6 oz / 170g) salmon fillets, skin-on
Look for fillets that are about 1 inch thick for even cooking. If you prefer skinless, that works too, but skin helps keep the fish moist.
1 teaspoon salt
Use fine sea salt for even seasoning. If using kosher salt, you may need a bit more.
1/2 teaspoon black pepper
Freshly ground black pepper gives the best flavor. Pre-ground works in a pinch.
2 tablespoons (30ml) olive oil
Use a good-quality extra virgin olive oil for sautéing. It adds a fruity note to the dish.
3 tablespoons (42g) unsalted butter
Unsalted butter lets you control the salt level. If using salted, reduce the added salt in the sauce.
4 cloves garlic, minced
Fresh garlic is key. Pre-minced jarred garlic can be used, but fresh gives a brighter flavor.
1 cup (240ml) heavy cream
Heavy cream (35% fat) creates the richest sauce. For a lighter version, use half-and-half, but the sauce will be thinner.
1/2 cup (50g) grated Parmesan cheese
Freshly grated Parmesan melts better than pre-shredded, which contains anti-caking agents. Pecorino Romano is a good substitute.
1/2 cup (75g) sun-dried tomatoes, drained and chopped
Use oil-packed sun-dried tomatoes for flavor. If using dry, rehydrate in warm water first.
3 cups (90g) fresh baby spinach
Baby spinach wilts quickly. You can substitute kale, but it needs a few extra minutes to soften.
1/2 teaspoon red pepper flakes (optional)
Adds a subtle kick. Omit for a milder sauce.
Fresh parsley, chopped, for garnish
Adds a fresh, bright finish. Dried parsley is not recommended.
Tips & Tricks
- Pat the salmon dry with paper towels before seasoning. This ensures a nice sear and prevents sticking.
- Don't overcook the salmon. It's done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).
- If the sauce gets too thick, add a splash of chicken broth or milk to thin it out.
- Use a large skillet to avoid overcrowding the salmon. If needed, cook in batches.
Pro Tips
Step-by-Step Instructions
1. Season the Salmon
Pat the salmon fillets dry with paper towels. Season both sides with salt and pepper. Heat olive oil in a large skillet over medium-high heat until shimmering.
2. Sear the Salmon
Place the salmon skin-side down in the skillet. Cook for 4-5 minutes without moving, until the skin is golden brown and crispy. Flip and cook for an additional 2-3 minutes. Transfer to a plate and set aside.
3. Make the Garlic Butter
Reduce heat to medium. Add butter to the same skillet. Once melted, add minced garlic and sauté for 30-60 seconds until fragrant, being careful not to burn it.
4. Add Cream and Tomatoes
Pour in the heavy cream and add the sun-dried tomatoes. Stir and bring to a gentle simmer. Cook for 2-3 minutes until the sauce slightly thickens.
5. Add Parmesan and Spinach
Sprinkle in the Parmesan cheese and stir until melted and smooth. Add the fresh spinach and cook for 1-2 minutes until wilted. Season with red pepper flakes, if using.
6. Return Salmon to Pan
Nestle the cooked salmon back into the sauce, skin-side down. Spoon some sauce over the top. Let it warm through for 1-2 minutes.
7. Garnish and Serve
Garnish with fresh parsley. Serve immediately with your choice of sides. Enjoy!
Delicious Variations
Chicken Version
Replace salmon with 4 boneless, skinless chicken breasts. Cook for 6-7 minutes per side until internal temperature reaches 165°F (74°C).
Add Mushrooms
Sauté 1 cup of sliced mushrooms with the garlic for extra earthy flavor.
Lemon Twist
Add the zest and juice of half a lemon to the sauce for a bright, citrusy kick.
How to Store Creamy Tuscan Garlic Butter Salmon
Refrigerator
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Freezer
Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat gently in a skillet over low heat, adding a splash of cream or broth to loosen the sauce. Avoid microwaving as it can overcook the salmon.
Frequently Asked Questions
Q: Can I use frozen salmon?
Yes, but thaw it completely in the refrigerator overnight and pat dry before cooking. Frozen salmon will release more water, so adjust cooking time.
Q: What can I substitute for heavy cream?
You can use half-and-half or canned coconut milk for a dairy-free option. The sauce will be slightly thinner, so simmer a bit longer to thicken.
Q: How do I know when the salmon is done?
The salmon is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).
Q: Can I make this dish dairy-free?
Yes, use a dairy-free butter substitute, coconut cream instead of heavy cream, and nutritional yeast or dairy-free Parmesan for the cheese. The flavor will be slightly different but still delicious.
Q: What sides go well with this dish?
It pairs well with pasta, rice, quinoa, roasted vegetables, or a simple green salad. For a low-carb option, try cauliflower mash or zucchini noodles.
