This air fryer salmon with fennel and orange zest cooks quickly, stays juicy, and gets a bright, aromatic finish from citrus zest and thin-sliced fennel. It’s a weeknight-friendly dinner that still feels a little special.
Why This Air Fryer Recipe Works
The air fryer’s circulating heat browns the surface fast, so the salmon develops lightly crisp edges without drying out. Since salmon cooks quickly, you can build flavor with simple aromatics rather than long marinades.
Fennel and orange are a classic pairing: fennel brings a clean, herbal crunch, while orange zest adds fragrance without extra liquid. A small amount of oil helps the seasoning cling and encourages browning.
- Fast cook time with minimal cleanup
- Bright, fresh flavor from fennel + orange zest
- Easy to scale for 2 to 4 servings
Ingredients You’ll Need
Choose center-cut salmon fillets if you can; they cook more evenly than thinner tail pieces. Skin-on or skinless both work—use what you like.
- 2 salmon fillets (about 6 oz each), patted dry
- 1 small fennel bulb, trimmed and very thinly sliced (reserve some fronds if you have them)
- Zest of 1 orange (use a microplane)
- 1 tablespoon fresh orange juice (optional, for finishing)
- 1 tablespoon olive oil, divided
- 1/2 teaspoon kosher salt, plus more to taste
- 1/4 teaspoon black pepper
- 1/2 teaspoon garlic powder (or 1 small grated garlic clove)
- Pinch of crushed red pepper flakes (optional)
If your fennel bulb is large, you may only need half. The goal is a light bed under/alongside the salmon, not a huge pile that steams.
How to Make Air Fryer Salmon with Fennel and Orange Zest in the Air Fryer
1) Prep the fennel. Slice fennel as thin as possible (a mandoline helps). Toss it with 1/2 tablespoon olive oil, a pinch of salt, and half of the orange zest.
2) Season the salmon. Rub the fillets with the remaining olive oil. Season with salt, pepper, garlic powder, and red pepper flakes if using. Sprinkle the remaining orange zest over the top.
3) Preheat and arrange. Preheat your air fryer for 3 minutes. Place fennel in the basket in a thin layer, then set the salmon fillets on or beside the fennel (depending on basket size) so air can circulate.
4) Air fry. Cook until the salmon flakes easily and the thickest part is just opaque. If you like a little more color on top, add 1–2 minutes at the end.
5) Finish and serve. Rest the salmon for 2 minutes. Squeeze a little orange juice over the top if you want extra brightness, and scatter fennel fronds if you have them.
Air Fryer Time and Temperature
Set the air fryer to 390°F. For most 1 to 1 1/4-inch thick fillets, plan on 8–11 minutes total.
- Thinner fillets (under 1 inch): 7–9 minutes
- Thicker fillets (1 1/2 inches): 10–12 minutes
- For extra browning: add 1–2 minutes, watching closely
Air fryers vary, so use the look and feel of the fish as your guide. The salmon should flake with gentle pressure and look moist, not raw, in the center.
Tips for the Best Results
Start with dry salmon. Patting the surface dry helps the oil and seasoning stick and encourages better browning.
Don’t overcrowd the basket. If the fennel is piled too thick or the fillets are touching, you’ll get more steaming than roasting.
- Slice fennel paper-thin so it softens quickly
- Preheat for more consistent timing
- Rest 2 minutes before serving to keep juices in the fish
- If the top is pale, move the fillets closer to the center and add 1 minute
If the fennel starts to brown too fast before the salmon is done, tuck it under the fish or give it a quick stir halfway through cooking.
Variations and Substitutions
Make this recipe fit what’s in your kitchen without changing the basic method.
- Lemon instead of orange: use lemon zest for a sharper, more savory finish.
- Dill or parsley: swap fennel fronds with chopped fresh dill or parsley.
- Honey-citrus glaze: whisk 1 teaspoon honey with 1 teaspoon orange juice and brush on during the last 2 minutes.
- Different fish: try arctic char or trout with the same time range; adjust for thickness.
- No fennel: use thin-sliced shallot or celery shaved into ribbons for crunch.
What to Serve With It
This salmon leans bright and aromatic, so simple sides work best. Choose something that can catch a little of the citrusy pan juices (even though it’s air fried, the plate will still have flavorful drips).
- Garlic rice or fluffy couscous
- Roasted baby potatoes or air fryer sweet potatoes
- Simple arugula salad with olive oil and a squeeze of orange
- Steamed green beans or asparagus

Storage and Reheating
Store leftover salmon and fennel in an airtight container in the refrigerator for up to 2 days. For best texture, keep the fennel separate if possible.
To reheat, warm salmon in the air fryer at 320°F for 3–5 minutes, just until heated through. Avoid high heat, which can dry it out and make the orange zest taste slightly bitter.

FAQ
Do I need to flip salmon in the air fryer?
Usually not. Air fryers circulate heat well enough that salmon cooks evenly without flipping, especially at 390°F. If your fillets are very thick, you can flip at the halfway mark, but it’s optional.
Can I use frozen salmon?
Yes, but thawing gives the best texture and seasoning coverage. If cooking from frozen, add a few minutes and season after the surface has thawed a bit (about 3–4 minutes in). Pat dry once it loosens, then continue cooking.
How do I keep salmon from sticking to the basket?
Lightly oil the basket or use perforated parchment made for air fryers. Skin-on salmon also releases more easily once it’s cooked. Don’t try to move it too early—give it a couple minutes to set.
What internal temperature should salmon be?
Many cooks pull salmon when the thickest part reaches around 125–135°F for moist, flaky fish, then let it rest briefly. If you prefer it more done, cook a bit longer. Use a quick-read thermometer for consistency.
Will the fennel get crispy?
It will soften and lightly brown at the edges, more like roasted fennel than chips. For more crispness, spread it in a very thin layer and cook it for 2 minutes before adding the salmon.
