Rich in anti-inflammatory omega-3 fatty acids, this dish combines perfectly flaky salmon with tender roasted asparagus for a complete, satisfying meal that won’t derail your ketogenic goals.

The asparagus roasts alongside the fish, absorbing those delicious flavors while providing essential nutrients and fiber. It’s elegant enough for dinner parties yet simple enough for busy weeknights.

Ingredients

• 680g (1.5 lbs / 4 fillets) salmon fillets, skin-on
• 450g (1 lb) fresh asparagus, trimmed
• 85g (6 tbsp) grass-fed butter, softened
• 4 cloves garlic, minced
• 15ml (1 tbsp) fresh lemon juice
• 15g (2 tbsp) fresh dill, chopped
• 10g (2 tbsp) fresh parsley, chopped
• 30ml (2 tbsp) extra virgin olive oil
• 5g (1 tsp) sea salt
• 2g (1/2 tsp) black pepper
• 2g (1/2 tsp) paprika
• 1g (1/4 tsp) garlic powder
• Lemon wedges for serving

Instructions

1. Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup.
2. Pat salmon fillets completely dry with paper towels. This ensures proper searing and prevents steaming.
3. In a small bowl, combine softened butter, minced garlic, fresh dill, parsley, and lemon juice. Mix until well incorporated.
4. Season salmon fillets on both sides with salt, pepper, paprika, and garlic powder. Let rest for 5 minutes to absorb flavors.
5. Toss trimmed asparagus with olive oil, salt, and pepper. Arrange on one side of the prepared baking sheet.
6. Heat a large oven-safe skillet over medium-high heat. If you don’t have one, use a regular skillet and transfer to baking sheet later.
7. Sear salmon fillets skin-side up for 3-4 minutes until golden brown. Don’t move them during this time for proper crust formation.
8. Carefully flip salmon fillets and spread half the garlic butter mixture on top of each fillet.
9. Transfer the skillet to the oven alongside the asparagus. If using a regular pan, transfer salmon to the baking sheet with asparagus.
10. Bake for 8-10 minutes until salmon flakes easily with a fork and internal temperature reaches 145°F (63°C).
11. Remove from oven and immediately top salmon with remaining garlic butter mixture while hot.
12. Let rest for 2-3 minutes, then serve immediately with roasted asparagus and fresh lemon wedges.

Nutrition Facts (per serving)

Chef’s Tips

• Choose salmon fillets of equal thickness (about 1.5 inches) to ensure even cooking. Wild-caught salmon has superior flavor and nutrition compared to farmed varieties.
• Don’t overcook the salmon – it should still be slightly translucent in the center when you remove it from the oven, as it will continue cooking from residual heat.
• For extra crispy asparagus, roast it for 2-3 minutes before adding the salmon to the oven. Thicker spears need more time than thin ones.

Health Benefits

This keto-friendly salmon recipe is a nutritional powerhouse that supports heart health, brain function, and weight management. The high omega-3 content helps reduce inflammation throughout the body, while the quality protein aids in muscle maintenance and satiety. Asparagus provides folate, vitamin K, and antioxidants that support liver detoxification. The healthy fats from salmon and butter help your body absorb fat-soluble vitamins and maintain stable blood sugar levels, making this dish perfect for sustained energy on a ketogenic diet.

Storage Instructions

Store leftover salmon and asparagus in the refrigerator for up to 3 days in airtight containers. Reheat gently in a 300°F (150°C) oven for 8-10 minutes to prevent overcooking. The garlic butter may separate when reheated but will still taste delicious. For best quality, consume within 2 days. This dish is not recommended for freezing as the texture of both salmon and asparagus deteriorates significantly.
