Ingredients
- 4 salmon fillets (6 oz each), skin removed
- 1 bunch asparagus, woody ends trimmed
- 1/2 cup unsalted butter, melted
- 4 garlic cloves, minced
- 1 tbsp lemon juice
- 1 tsp lemon zest
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/4 tsp paprika
- 1 tbsp olive oil
- 1/4 cup fresh parsley, chopped
Instructions
- Step 1: Prepare the air fryer by preheating to 400°F for 3 minutes. Line the basket with parchment paper for easy cleanup.
💡 Tip: Use a non-stick air fryer basket if parchment paper isn't available.
- Step 2: In a small bowl, whisk together melted butter, garlic, lemon juice, zest, salt, pepper, and paprika. Brush half the mixture over salmon fillets.
💡 Tip: For extra flavor, let the salmon marinate for 15 minutes before cooking.
- Step 3: Toss asparagus with olive oil, salt, and remaining garlic butter mixture. Arrange in the air fryer basket around salmon fillets.
💡 Tip: Use a small wire rack to separate salmon and asparagus for even cooking.
- Step 4: Cook for 12-15 minutes, until salmon reaches 145°F and asparagus is tender-crisp. Sprinkle with fresh parsley before serving.
💡 Tip: Check for doneness with a fork - salmon should flake easily but remain moist.

Ingredient Notes & Substitutions
Salmon Fillets
Look for wild-caught salmon for best flavor and texture. For a more budget-friendly option, use salmon steaks cut into portions.
Substitutions: Cod, halibut, or trout can be used. Adjust cooking time as needed.
Asparagus
Choose thick spears for better texture. To save time, use pre-trimmed asparagus from the grocery store.
Substitutions: Broccoli florets or sugar snap peas work well as alternatives.
Butter
Unsalted butter is recommended to control seasoning levels. For a dairy-free version, use vegan butter.
Substitutions: Olive oil can be substituted, but it won't provide the same rich flavor.
Lemon
Fresh lemon juice is essential for brightness. Avoid bottled juice as it lacks the aromatic oils.
Substitutions: Lime juice can be used for a different flavor profile.
Pro Tips for Perfect Garlic Butter Salmon
🍴 Salmon Handling
Pat salmon dry before adding butter sauce to ensure proper browning. Avoid flipping during cooking to maintain flakiness.
🔥 Air Fryer Techniques
Use the air fryer's top rack position for even cooking. For extra crispy asparagus, cook for 2 additional minutes after salmon is done.
🍋 Flavor Boosters
Add a squeeze of fresh lemon juice to each serving just before eating. Garnish with additional parsley for color and freshness.
❄️ Make Ahead Tips
Prepare the butter sauce up to 24 hours in advance. Store in refrigerator and bring to room temperature before using.
Variations & Customizations
Vegan Version
Use vegan butter and substitute salmon with marinated tofu or tempeh. Add nutritional yeast for umami flavor.
Spicy Kick
Add 1/2 tsp chili flakes to the butter sauce for a smoky heat. Serve with a cooling yogurt raita.
Herb Infusion
Mix in 1 tbsp fresh dill or thyme with the butter sauce for additional herbal notes. Pair with herb-infused rice.
Cheesy Twist
Sprinkle grated Parmesan over the salmon during last 2 minutes of cooking for a golden, cheesy crust.

Make-Ahead Instructions & Storage

Troubleshooting & Common Questions
Q: How to tell when salmon is done?
A: Use a fork to gently flake the thickest part. The flesh should be opaque with a slight translucency in the center.
Q: Can I use frozen asparagus?

Q: How to prevent salmon from sticking?
A: Make sure the air fryer basket is properly lined with parchment paper or use a non-stick spray.

Made this on a rainy Tuesday night, and the kitchen smelled cozy. The salmon shone in a garlic butter glaze after 12 minutes, air-fried, while the asparagus kept its snap, perfectly every time. Tested adding a splash of lemon juice at the end to brighten the richness and balance the buttery notes. Four stars because the dinner was delicious, ideal on crisp fall evenings, but the asparagus could be a touch softer with a perfect bite, the lemon finish added bright citrus.
