Air Fryer Keto Salmon With Lemon Dill - Quick, Fresh, and Flavorful
Ingredients
Method
- Preheat the air fryer: Set your air fryer to 390°F (200°C). Lightly spray or brush the basket with oil so the salmon won’t stick.
- Pat the salmon dry: Use paper towels to remove excess moisture.Dry fish sears better and gets a nicer surface.
- Season the fillets: Rub salmon with olive oil. Mix salt, pepper, garlic powder, onion powder, and smoked paprika. Sprinkle evenly on all sides.If your fillets have skin, season the flesh side more generously.
- Make the lemon-dill butter: In a small bowl, stir together melted butter, lemon zest, lemon juice, and chopped dill. Taste and add a pinch of salt if needed. Set aside.
- Arrange in the basket: Place salmon in the air fryer basket skin-side down in a single layer with a little space between pieces.Don’t stack.
- Air fry: Cook for 7–10 minutes, depending on thickness. A general guide is about 7 minutes for 1-inch-thick fillets. The salmon is done when it flakes easily and reaches an internal temperature of 125–130°F for moist medium or up to 140°F if you prefer it more well done.
- Baste and finish: In the last 1–2 minutes of cooking, spoon or brush half the lemon-dill butter over the salmon.Close the air fryer to let the butter warm and infuse.
- Rest and serve: Transfer salmon to plates, drizzle with the remaining lemon-dill butter, and garnish with extra dill. Serve with lemon wedges.

How to Store
- Refrigerate: Store cooked salmon in an airtight container for up to 3 days. Keep the lemon-dill butter separate if you have extra.
- Reheat gently: Warm in the air fryer at 320°F for 3–4 minutes or in a covered skillet over low heat.Avoid overcooking so it stays moist.
- Freeze: For best texture, enjoy fresh. If freezing, wrap tightly and freeze up to 2 months. Thaw overnight in the fridge and reheat gently.
Health Benefits
- Rich in omega-3s: Salmon provides EPA and DHA, which support heart, brain, and joint health.
- High-quality protein: Helps maintain muscle mass and keeps you satisfied on a keto diet.
- Nutrient-dense: Salmon is a source of B vitamins, selenium, and potassium, while dill and lemon add antioxidants and vitamin C.
- Keto-aligned fats: Butter or ghee and olive oil contribute satiating fats without carbs or added sugars.
What Not to Do
- Don’t crowd the basket: Overlapping fillets steam instead of crisping.Cook in batches if needed.
- Don’t skip drying the fish: Moisture on the surface prevents good browning and can make the texture soft.
- Don’t overcook: Dry salmon happens fast. Pull it as soon as it reaches your target temperature.
- Don’t add the lemon too early: Too much acid at the start can make the surface mushy. Baste near the end for bright flavor.
- Don’t forget the salt: Proper seasoning brings out the salmon’s natural sweetness.
Recipe Variations
- Garlic-dill mayo finish: Swap the butter for 2 tablespoons avocado oil mayo mixed with lemon juice, dill, and minced garlic.Spoon over after cooking.
- Herb blend: Mix dill with parsley or chives for a softer, garden-fresh profile.
- Spicy twist: Add 1/4 teaspoon crushed red pepper or a pinch of cayenne to the seasoning mix.
- Dairy-free: Use ghee or a dairy-free butter alternative, or finish with extra-virgin olive oil.
- Mustard kick: Whisk 1 teaspoon Dijon into the lemon-dill butter for gentle tang.
- Sheet-pan option: No air fryer? Bake at 400°F for 10–12 minutes, then broil 1–2 minutes to lightly brown. Baste with the lemon-dill butter at the end.
FAQ
Can I use frozen salmon?
Yes, but thaw it first for even cooking.
Pat it very dry after thawing to remove excess moisture, then follow the recipe as written.
Should I keep the skin on?
Skin-on helps keep the salmon moist and makes it easier to remove from the basket. After cooking, the flesh will slip off the skin if you prefer not to eat it.
How do I know when salmon is done?
Look for opaque flesh that flakes easily with a fork. For the most reliable result, use a thermometer.
Aim for 125–130°F for tender, medium salmon.
What sides go well with this?
Try cauliflower rice with sautéed spinach, a simple arugula salad, roasted asparagus, or zucchini ribbons tossed in olive oil and lemon.
Can I make this without dill?
Yes. Use parsley, chives, or tarragon. The flavor will change, but the lemon and butter base still tastes great.
Is this recipe meal-prep friendly?
Absolutely.
Cook the salmon, cool it, and store in portions. Reheat gently and finish with a fresh squeeze of lemon and a sprinkle of dill.
Can I cook different-sized fillets together?
You can, but check the thinner pieces early and remove them as they finish. Keeping sizes similar makes timing easier.
What if I don’t have lemon?
Use a splash of apple cider vinegar or white wine vinegar and a little extra zest from any citrus you have.
Lemon is best, but acid plus dill still works.
