Ingredients You’ll Need
For the Salmon
- 2 (6-8 oz) salmon fillets, skin-on or skinless
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/2 tsp paprika (optional for color)
- 1 tbsp olive oil
For the Garlic Butter Sauce
- 3 tbsp unsalted butter
- 4 garlic cloves, minced
- 1/4 tsp red pepper flakes (optional)
- 2 tbsp lemon juice
- 1 tsp honey or maple syrup
- 1 tbsp chopped fresh parsley
For the Spinach
- 5 oz fresh baby spinach (about 4 cups packed)
- Pinch of salt
Step-by-Step Instructions
1. Prep the Salmon
- Pat salmon fillets very dry with paper towels (this ensures a perfect sear).
- Season both sides with salt, pepper, and paprika.
2. Sear the Salmon
- Heat olive oil in a large skillet over medium-high heat.
- Once hot, add salmon skin-side down (if using skin-on).
- Cook for 4-5 minutes until golden and crispy.
- Flip and cook for 2-3 minutes more, then transfer to a plate.
3. Make the Garlic Butter Sauce
- In the same skillet, reduce heat to medium.
- Add butter and let melt, then add garlic and red pepper flakes.
- Cook for 30 seconds until fragrant (don’t let garlic burn!).
- Stir in lemon juice and honey.
4. Wilt the Spinach
- Add spinach to the skillet with a pinch of salt.
- Toss for 1-2 minutes until just wilted (it will cook down dramatically).
5. Bring It All Together
- Return salmon to the skillet, spooning sauce over it.
- Garnish with fresh parsley.
- Serve immediately with lemon wedges.
Pro Tips for Perfect Salmon Every Time
🔥 Get the pan HOT before adding salmon for that restaurant-quality sear
⏲ Don’t overcook – salmon is done at 125°F internal temp (it will keep cooking off heat)
🍋 Fresh lemon is key – bottled juice can’t compare
🧈 Brown the butter for 30 seconds for extra nutty flavor
🥬 Spinach alternatives – try kale or Swiss chard for variation
Serving Suggestions
- With carbs: Serve over mashed potatoes, rice, or crusty bread to soak up sauce
- Low-carb: Pair with roasted asparagus or zucchini noodles
- For entertaining: Plate with a white wine like Chardonnay or Sauvignon Blanc
