🧄 Ingredients
For the Salmon:
- 4 salmon fillets (about 6 oz each), skin-on or skinless
- Salt and black pepper, to taste
- 1 tablespoon olive oil
- 2 tablespoons butter
For the Garlic Butter Sauce:
- 3 tablespoons butter
- 4 cloves garlic, minced
- 8 oz mushrooms, sliced (cremini or button work great)
- 3 cups baby spinach, rinsed and dried
- 1/2 cup chicken or vegetable broth
- 1 tablespoon lemon juice (freshly squeezed)
- 1/4 teaspoon red pepper flakes (optional, for a gentle kick)
- 1 tablespoon chopped fresh parsley (plus more for garnish)
Optional Additions:
- 1/4 cup grated Parmesan cheese for richness
- A splash of white wine for depth of flavor
👩🍳 Instructions
Step 1: Season and Sear the Salmon
Pat the salmon fillets dry with paper towels, then season both sides with salt and black pepper.
Heat olive oil and 2 tablespoons of butter in a large skillet over medium-high heat.
Add the salmon fillets, skin-side down first, and sear for 3–4 minutes per side until golden and cooked through. Remove from the skillet and set aside on a plate.
Step 2: Sauté the Mushrooms
In the same skillet, melt 3 tablespoons of butter over medium heat. Add the sliced mushrooms and cook for 4–5 minutes, stirring occasionally, until they’re browned and tender.
Step 3: Add Garlic and Spinach
Stir in the minced garlic and cook for 30 seconds until fragrant (be careful not to burn it). Add the spinach and cook just until wilted, about 1–2 minutes.
Step 4: Make the Sauce
Pour in the chicken or vegetable broth and lemon juice, scraping up any flavorful bits from the bottom of the pan. Simmer for 2–3 minutes until the sauce slightly reduces. If using Parmesan or white wine, add them now for a deeper, creamier flavor.
Step 5: Combine Everything
Return the salmon fillets to the skillet, spooning some of the garlic butter sauce over the top. Simmer for another 2 minutes to let the flavors meld together.
Step 6: Serve and Enjoy
Garnish with fresh parsley and a wedge of lemon. Serve warm with rice, pasta, mashed potatoes, or simply enjoy it as a low-carb meal straight from the pan.
💡 Tips for Success
- Don’t overcook the salmon: It’s done when it flakes easily with a fork and turns opaque.
- Use fresh garlic: It makes the flavor shine — garlic powder won’t do it justice here.
- Deglaze with wine: A splash of white wine adds beautiful acidity and richness.
- Fresh spinach works best: Frozen spinach releases too much water into the sauce.
- Butter quality matters: Use real butter for that silky, restaurant-style texture.
🍋 Flavor Variations
Creamy Garlic Butter Salmon:
Add 1/4 cup heavy cream and a bit of Parmesan to the sauce for a creamy twist.
Cajun Style:
Season the salmon with Cajun spices before searing for a spicy Southern flair.
Asian-Inspired:
Add a drizzle of soy sauce and a touch of honey for a sweet-salty glaze.
Mediterranean Touch:
Toss in sun-dried tomatoes, capers, or artichoke hearts for bright, tangy layers.
Herb Upgrade:
Add a mix of thyme, basil, or dill to the butter sauce for extra aroma.
🍽️ Serving Suggestions
Serve your Garlic Butter Salmon with Spinach and Mushrooms alongside:
- Steamed rice or quinoa for a healthy base.
- Creamy mashed potatoes or cauliflower mash for a comforting touch.
- Buttered pasta tossed with lemon zest.
- Garlic bread and a crisp green salad for a light, elegant meal.
Pair it with a chilled glass of white wine or sparkling water with lemon for a perfect balance.
🧊 Storage & Reheating
Refrigerator:
Store leftovers in an airtight container for up to 3 days.
Freezer:
Freeze salmon and sauce (without spinach) for up to 2 months. Thaw overnight before reheating.
Reheating:
Warm gently in a skillet over low heat, adding a splash of broth or butter to revive the sauce. Avoid microwaving for too long, as salmon can dry out.
