What’s in this salmon and asparagus recipe?

This salmon sheet pan meal pairs luscious fish with a robust lemon sauce that will rock your world! Here’s what you’ll need for this baked salmon with lemon recipe:

  • Salmon: You can either use a whole 1 pound side of salmon, or 4 (4 ounce) salmon fillets. If possible, opt for wild salmon for the best taste!
  • Asparagus: You’ll need 1 and 1/2 to 2 pounds of this asparagus spears.
  • Lemon: It wouldn’t be lemon salmon without lots of bright lemon flavor! This recipe uses 2 lemons. The juice and zest of one will go right into the sauce. The other lemon is sliced and used on top of the fish.
  • Garlic: A clove of minced garlic provides a touch of mellow flavor.

What to know about buying salmon

The quality of your salmon is extremely important for this simple sheet pan dinner! Here’s what to look for when you are looking for salmon at the grocery store:

  • Fresh is best! If you’re looking for the very best asparagus salmon dinner, make sure you buy fresh fish from your local seafood provider. However, frozen salmon works find if that’s all you can find.
  • Smells like the ocean! Make sure your salmon smells fresh like the salty ocean – without any off-putting or fishy odors.
  • Wild caught salmon is best! Wild caught fish is typically the most sustainable option. However, you can find quality farm raised fish – just check the seafood consumer guide.
  • The five most popular types of salmon are King Salmon (chinook salmon), Coho Salmon (silver salmon), Pink Salmon (humpback salmon), Sockeye Salmon (red salmon) and keta salmon. King salmon is by far the richest in flavor. Coho salmon is a good middle of the road fish with a delicate flavor and firm texture. For this asparagus salmon dinner I recommend using King salmon or coho salmon.

Expert tips for the best success!

  1. Salmon: You can either use one large filet of salmon for this baked asparagus with salmon. Alternatively, you can cut the filet into smaller portions if you prefer. You can easily scale this dinner recipe up or down to feed as many mouths as you need.
  2. Lemony flavor: If you prefer a stronger lemon flavor, add more lemon zest to the lemon dijon sauce. On the other hand, if you prefer a subtle hint of lemon, use less zest.
  3. For a crisper top on your salmon, I recommend you broil it for the last few (3-5) minutes of cooking. After you switch the oven to high broil, make sure you watch the salmon very carefully as it can go from golden brown to burnt very quickly!
  4. The baking time for the asparagus salmon recipe below is approximate. It will really depend on how thick your salmon is and your desired doneness. Salmon is cooked through when it flakes easily with a fork.

FAQs: frequently asked questions

What herbs go with lemon dijon salmon?

Fresh herbs are the perfect way to add flavor and take your one sheet salmon and asparagus from good to great.

  • Dill: Feathery dill leaves lend a fresh, sharp flavor!
  • Parsley: The mild, grassy flavor of flat-leaf parsley won’t outshine the other ingredients.
  • Basil: Sweet basil’s faint licorice flavor brightens lemon’s taste.
  • Chives: The delicate onion flavor found in chives is a harmonious pairing with lemon!
  • Chervil: Sometimes called French parsley, chervil has a delicate flavor enhanced by a hint of anise.
  • Thyme: The earthiness of thyme is a wonderful complement to tart lemon flavor!

Pro-tip: Make sure you add fresh herbs to your salmon after cooking to garnish the dish. This will ensure the fresh flavors remain bright and fresh. And make sure you are storing fresh herbs properly, too!

Will lemon juice cook salmon?

Technically, lemon will not cook salmon as cooking requires heat.

However, lemon juice or any acid, such as lime, orange and grapefruit, will denature fish flesh. Meaning, the acid will change the molecular structure of the fish’s flesh and make it firmer and more opaque, similar to cooking.

In the Peruvian dish, ceviche, raw fish is “cooked” in an acid and then served as is, without any cooking over heat.

The lemon juice in this recipe is simply being used as a flavoring agent. The salmon doesn’t sit, or marinate, in the lemon juice long enough to acutally “cook” (or denature) the fish.

How long to bake salmon at 425?

The length of time salmon requires to cook in the oven depends on a few different variables, namely – the thickness of the fish and the doneness desired.

Salmon can quickly go from undercooked to way overcooked. Make sure you avoid overcooking salmon or it will become dry and unappetizing!

There are two ways to tell when salmon is done:

  • Thermometer: The best way to check fish for doneness is to use an instant read thermometer. The USDA recommends a minimum internal temperature of 145°F, which should be measured at the thickest part of the fish.
  • Sight: If you don’t have a thermometer you can check fish for doneness by using your sight and a fork. Salmon is ready when it flakes fairly easily with a fork.

This dijon lemon salmon cooked in an oven preheated to 425°F will take approximately 10-15 minutes to cook.

Serving salmon & asparagus

What goes with this salmon and asparagus bake?

This Lemon dill salmon is baked right alongside fresh asparagus and can be served as a lighter, healthier meal!

However, if you are looking to add more sustenance and complete this baked salmon dinner, below are a few delicious side dish options!

Storing leftovers

How long will leftover asparagus salmon keep?

To Store: Place cooled leftover salmon in a shallow airtight container or wrap it tightly with plastic wrap. Store salmon in the refrigerator for up to 3 to 4 days.

To Reheat: Salmon is best enjoyed on the day it is cooked, as salmon has a tendency to dry out once reheated. I recommend serving leftover cooked salmon cold or at room temperature. Try flaking the salmon and serving it on sandwiches or over a salads. Or, flake the salmon into pieces and add it to scrambled eggs!

Notes

  1. Salmon: You can either use one large filet of salmon for this recipe, or you can cut the filet into smaller serving portions if desired.  As well, this recipe scales up and down really easily depending on how many people you are feeding!  If feeding a crowd, make sure you use more than one sheet pan and rotate the pans in the oven, from top to bottom and front to back, half way through cooking.
  2. Lemony Flavor: If you like a stronger lemon flavor, add more lemon zest to the Lemon Dijon salmon mixture in step 3. alternatively, if you prefer a more subtle lemon flavor, use less lemon zest. (Note: The zest contains more flavor than the juice!)
  3. Basil Aioli: The basil sauce is totally optional; however, I think sauce is life. If you are making the aioli, just be sure to hand whisk the ingredients together. Using a food processor or blender will cause the sauce to separate!
  4. Broiling Salmon: If you want a crisper top on your salmon, I recommend you broil it for the last few (3-5) minutes of cooking.  After you switch the oven to high broil, make sure you watch the salmon CAREFULLY as it can go from golden brown to burnt very quickly!
  5. The cooking time in the recipe is approximate. It will really depend on how thick your salmon is and your desired doneness.  Salmon is cooked through when it flakes easily with a fork.
