Step 1: Prepare the Ingredients : Rinse and pat dry the salmon fillets. Trim the woody ends of the asparagus. Mince the garlic and zest the lemon.

Step 2: Season the Salmon : Lightly season both sides of each salmon fillet with salt, pepper, and paprika (if using). Set aside.

Step 3: Sear the Salmon : Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Once hot, add salmon fillets skin-side down (if using skin-on). Sear for 4–5 minutes, until golden and crispy. Carefully flip the fillets and cook another 2–3 minutes until salmon is just cooked through. Transfer the salmon to a plate and cover loosely with foil to keep warm.

Step 4: Cook the Asparagus : In the same pan, melt the remaining 2 tablespoons butter. Add minced garlic and sauté for 30 seconds, just until fragrant. Add the asparagus and cook for 4–5 minutes, tossing occasionally until tender-crisp. Season lightly with salt and pepper.

Step 5: Combine Everything : Return the salmon fillets to the skillet alongside the asparagus. Squeeze fresh lemon juice over everything, sprinkle with zest, and spoon the garlic butter sauce over the top. Cook for another 1 minute to heat through.

Step 6: Garnish and Serve : Sprinkle with freshly chopped parsley and garnish with lemon slices. Serve immediately.
