How Do I Know When the Salmon is Fully Cooked in the Air Fryer?
The best way to check is with an instant-read thermometer. Salmon is safe to eat when it reaches an internal temperature of 145°F at its thickest point. If you don’t have a thermometer, look for these visual cues: the flesh should be opaque all the way through and flake easily when pressed gently with a fork. Always check a few minutes early so you don’t overcook it. Salmon dries out quickly once it goes past done.
Pro Tip for the Salmon Recipe
Place the asparagus in the basket first, then lay the salmon directly on top. This positions the salmon closer to the heating element for a better sear while the asparagus steams slightly underneath — giving you two perfect textures at once.
Ingredient Notes for this Seafood Recipe
You only need six simple ingredients to pull this recipe together beautifully.
This is an overview of key ingredients. Get the full printable recipe with specific measurements and directions in the recipe card below.
- Salmon: One pound is the sweet spot for 4 servings. You can use one large salmon fillet or individual portions — both work well.
- Lemon Pepper Seasoning: This does double duty, going on both the salmon and the asparagus. It ties the whole dish together with a bright, peppery kick.
- Texas Seasoning: This goes on the salmon only and adds a smoky, savory layer. Swap in your favorite steak seasoning if you don’t have Texas Seasoning on hand.
- Garlic Salt: Also used on both the salmon and the asparagus. It adds savory depth without requiring fresh garlic.
- Olive Oil: Used only on the asparagus to help it roast rather than steam. Don’t skip it — it makes a real difference in texture.
- Asparagus: Wash and trim the woody ends before cooking. Thinner stalks will cook faster than thick ones, so adjust your time if needed.
Variations and Substitutions this Easy Salmon Dinner
This one pan recipe is incredibly flexible. A few easy swaps can take it in a completely different direction. Perfect for people who love salmon.
➡️ Swap the Protein: Use a thick-cut tilapia or cod fillet in place of salmon for a milder flavor profile.
➡️ Change the Seasoning: Try Cajun seasoning, Old Bay Seasoning, or a simple herb blend in place of the Texas Seasoning.
➡️ Replace the Asparagus: Use zucchini sticks, green beans, or bell pepper strips for a fun variation.
➡️ Add a Finishing Sauce: Serve with a lemon dill sauce or a drizzle of garlic butter right before plating. Top with a lemon slice.
➡️ Use Skin-on Salmon: Skin-on fillets work perfectly here and help hold the fish together during cooking.
Kitchen Tools To Make the Best Salmon
You only need two things in your kitchen to make this recipe work.
- Air Fryer: Any standard basket-style air fryer works well. Make sure your basket is large enough to fit the salmon on top of the asparagus in a single layer.
- Measuring Spoons: The seasoning ratios matter here, so measure rather than eyeball for the best results.
How to Make the Air Fryer Salmon Recipe
The salmon comes out perfectly tender with those caramelized edges the air fryer is so good at, and the asparagus gets just enough char to taste like it came off a grill. Everything cooks in the same basket, everything’s seasoned simply, and the whole meal is ready in minutes.
These are just highlights. Get the full printable recipe with specific measurements and directions in the recipe card below.
- Season the Salmon: First, season generously with lemon pepper, garlic salt, and Texas Seasoning.
- Load the Basket: By placing the asparagus in first, then drizzling it with olive oil.
- Season the Asparagus: Use lemon pepper and garlic salt right in the basket.
- Add the Salmon: Place on top of the asparagus and slide the basket into the air fryer.
- Air fry: At 350°F for 15–18 minutes until the salmon is cooked through and the asparagus is tender.
Prep Ahead and Short Cut Tips for Garlicky Salmon
A little advance work makes this recipe even faster on busy weeknights.
➡️ Season ahead: Coat the salmon with all three seasonings up to 24 hours in advance and store it covered in the refrigerator until ready to cook.
➡️ Trim in advance: Wash and trim the asparagus the night before and store it in a zip-top bag in the fridge.
➡️ Pre-measure seasonings: Combine the lemon pepper and garlic salt together in a small bowl ahead of time so seasoning both components is faster.
Alternate Cooking Methods – Sheet Pan Baked Salmon and Asparagus
If you don’t have an air fryer, you can still pull this recipe off with great results.
- Oven Method: Place the asparagus on a rimmed sheet pan, drizzle with olive oil, and season as directed. Lay the salmon on top, season it, and roast at 400°F for 12–15 minutes until the salmon flakes easily.
- Stovetop Method: Cook the seasoned salmon in a skillet over medium-high heat for three to four minutes per side. Cook the asparagus separately in the same pan with a drizzle of olive oil until tender-crisp.
Can I Use Frozen Salmon in this Air Fryer Salmon Recipe?
Yes, you can but you’ll want to thaw it completely first for the best results. Cooking salmon from frozen in the air fryer is possible, but it releases a lot of moisture, which makes getting that nicely seasoned, slightly crispy exterior much harder.
Store, Reheat, and Use Leftover Salmon with Asparagus
- Storing: Let the salmon and asparagus cool completely before storing. Place leftovers in an airtight container and refrigerate for up to three days.
- Reheating: Reheat in the air fryer at 300°F for three to four minutes to warm through without drying out the salmon. Avoid the microwave if possible — it tends to make the fish rubbery and the asparagus soggy.
- Using Leftovers: Leftover salmon flakes beautifully over a green salad or into a grain bowl with the asparagus spears, rice, and a squeeze of fresh lemon juice. You can also mix it into scrambled eggs or fold it into a wrap with avocado for a quick lunch the next day.
Expert Tips for Making This Roasted Salmon Recipe
Here are a few tips I have discovered after making the salmon fillets and asparagus dish.
➡️Don’t Skip Preheating. I always preheat my air fryer for three to five minutes before adding the food. It gives the salmon a better crust right from the start.
➡️ Pat the Wild Caught Salmon Dry First. I pat the surface of the salmon dry with a paper towel before seasoning. This helps the seasonings stick and gives you a crispier exterior.
➡️Check at 15 Minutes. I always pull the basket at the 15-minute mark and check to see if salmon is done before going to 18 minutes. Overcooking salmon even slightly changes the texture significantly.

Ingredients
- 1 pound Salmon
- 2 tablespoons Olive oil
- 2 tablespoons Lemon pepper seasoning
- 1 tablespoon Garlic salt
- 2 tablespoons Texas Seasoning, or favorite steak seasoning
- 1 pound Asparagus, washed and trimmed
Instructions
- Generously season the salmon on all sides with the lemon pepper seasoning, garlic salt, and Texas Seasoning.
- Arrange the asparagus in a relatively even layer in the air fryer basket. Drizzle the olive oil over the asparagus, then season with the lemon pepper seasoning and garlic salt.
- Place the seasoned salmon skin-side down on top of the asparagus.
- Air fry at 350℉ for 15 to 18 minutes, checking once around the 15-minute mark. Adjust the cooking time as needed based on the thickness of the salmon and asparagus.
- Remove the salmon and asparagus from the air fryer and let the salmon rest for 2 to 3 minutes before serving.
Christina’s Notes
- Don’t skimp on the seasoning. A generous coating of the three seasonings gives the salmon its bold, flavorful crust.
- Keep the asparagus in a single layer. Crowding the basket can cause it to steam instead of roast.
- Thick asparagus needs a head start. If your asparagus is particularly thick, add it to the air fryer 3 to 4 minutes before adding the salmon.
- Don’t keep opening the air fryer. Check once around 15 minutes so you don’t unnecessarily release heat or extend the cooking time.
- Let the salmon rest. A 2- to 3-minute rest allows the juices to redistribute and the salmon to finish cooking slightly.
- Use fresh asparagus. Look for firm stalks with tight, closed tips.
- Scale the recipe: Simply adjust the serving size in the recipe card and the ingredients will update automatically.
- Make your own All Purpose Seasoning: When a recipe calls for All Purpose Seasoning, you can use my homemade All Purpose Seasoning recipe or substitute salt and pepper to taste.
- Meat doneness: I always use a meat thermometer to test for doneness when cooking meat.
- Use unsalted butter: I use unsalted butter so I can control the salt level in the recipe.
- Preheat the oven: Unless otherwise noted, always preheat your oven before baking.
