Ingredients for Garlic Butter Salmon with Spinach Mushrooms
This recipe serves 4, featuring four succulent salmon fillets. Here’s what you’ll need for the salmon, sauce, and veggie side.
For the Salmon
4 salmon fillets (6 oz or 170g each), skin-on or skinless
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon paprika (for color and flavor)
1 tablespoon olive oil
For the Garlic Butter Sauce
4 tablespoons unsalted butter
4 cloves garlic, minced
1 tablespoon lemon juice
1 teaspoon lemon zest
1 tablespoon fresh parsley, chopped (plus extra for garnish)
¼ teaspoon red pepper flakes (optional, for a kick)
For the Spinach Mushrooms
2 cups fresh spinach (about 60g)
1 cup cremini or button mushrooms, sliced (about 100g)
1 tablespoon olive oil
1 clove garlic, minced
¼ teaspoon salt
¼ teaspoon black pepper
Equipment Needed
Large skillet (preferably non-stick)
Spatula
Small bowl
Tongs
Knife and cutting board
Step-by-Step Instructions
Follow these easy steps to create a gourmet garlic butter salmon dish in under 30 minutes!
Step 1: Prepare the Salmon
Pat the salmon fillets dry with paper towels. Season both sides with salt, pepper, and paprika. This dry seasoning ensures a flavorful crust when seared.
Step 2: Sear the Salmon
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Place the salmon fillets skin-side down (if using skin-on) and cook for 4-5 minutes until the skin is crispy and golden. Flip and cook for another 2-4 minutes, or until the internal temperature reaches 145°F (63°C). Remove from the skillet and set aside.
Step 3: Make the Garlic Butter Sauce
In the same skillet, lower the heat to medium and add the butter. Once melted, stir in the minced garlic and cook for 1 minute until fragrant. Add lemon juice, lemon zest, parsley, and red pepper flakes (if using). Stir for another 30 seconds, then remove from heat. This sauce will be spooned over the salmon for an extra layer of flavor.
Step 4: Cook the Spinach Mushrooms
In a separate skillet, heat 1 tablespoon of olive oil over medium heat. Add the minced garlic and sauté for 30 seconds. Add the sliced mushrooms and cook for 3-4 minutes until they release their moisture and turn golden. Stir in the spinach, salt, and pepper, cooking for 1-2 minutes until wilted. Remove from heat.
Step 5: Assemble and Serve
Place a portion of the spinach-mushroom mix on each plate. Top with a salmon fillet and spoon the warm garlic butter sauce generously over the fish. Garnish with extra parsley for a fresh finish. Serve immediately with sides like mashed potatoes, quinoa, or crusty bread to soak up the sauce.
Tips for the Perfect Garlic Butter Salmon
Don’t Overcook: Salmon cooks quickly—use a meat thermometer to ensure it reaches 145°F (63°C) for perfect doneness.
Crisp Skin: If using skin-on fillets, start with the skin side down and press gently with a spatula for the first minute to prevent curling.
Sauce Variations: Add a splash of white wine or cream to the garlic butter for a richer sauce.
Make Ahead: Prep the spinach-mushroom mix and sauce in advance, then reheat and sear the salmon when ready to serve.
Freshness Matters: Use fresh salmon and herbs for the best flavor.
Pairing Suggestions
Enhance your meal with these complementary sides:
Starchy Sides: Creamy mashed potatoes or garlic roasted potatoes pair beautifully with the sauce.
Grains: Serve with wild rice or quinoa for a nutritious boost.
Veggie Sides: Steamed asparagus or glazed carrots add color and crunch.
Drink Pairing: Pair with a crisp Chardonnay or sparkling water with lemon for a refreshing contrast.
Nutritional Benefits
This dish is a nutritional powerhouse! Salmon is rich in omega-3 fatty acids, supporting heart and brain health, while spinach and mushrooms provide vitamins A, C, and K, plus antioxidants. Each serving (one fillet with sauce and veggies) contains approximately:
Calories: 400-450 kcal
Protein: 35g
Fat: 25g
Carbohydrates: 5g
For a lighter option, reduce the butter or serve with extra veggies.
Variations to Try
Spicy Twist: Increase red pepper flakes or add a dash of hot sauce to the sauce.
Creamy Upgrade: Stir in ¼ cup heavy cream for a velvety texture.
Herb Swap: Use dill or chives instead of parsley for a different flavor profile.
Vegetarian Version: Replace salmon with grilled tofu or portobello mushrooms.

FAQs

How do I store leftovers?Store cooked salmon and veggies separately in airtight containers in the fridge for up to 2 days. Reheat gently in a skillet or oven to avoid overcooking.
Can I use frozen salmon?Yes, thaw completely in the fridge overnight and pat dry before seasoning and cooking.
Is this dish very garlicky?The garlic flavor is prominent but balanced—reduce to 2 cloves if you prefer a milder taste.
Can I make the sauce ahead of time?Yes, prepare the sauce up to a day in advance and reheat gently, adding a splash of lemon juice if it thickens.
