What you’ll need

ingredients to make dijon garlic salmon

Salmon – this recipe will work with any cut of fresh salmon (or rainbow trout), either skin-on or skinless. You can even start with frozen salmon, just be sure to thaw completely first. Tip! Quickly thaw frozen salmon by placing it in a bag and then into a large bowl of cold water.

Mayonnaise – don’t skip the mayo! Mayonnaise is used here as a coating for the fresh herbs, ensuring that they don’t burn in the oven. Real, full-fat mayonnaise is recommended.

Dijon Mustard – regular Dijon mustard is recommended here. You could use grainy mustard, in a pinch.

Garlic – start with fresh garlic, for the best flavour. Be sure to chop the garlic quite fine.

Worcestershire Sauce – this brings a little salty, umami flavour to the topping. You can omit if you don’t have any on hand.

Fresh Parsley – you can use either curly or flat fresh parsley for this recipe. In a pinch, if you only have dried parsley on hand, you can use it. As a general rule, use only about 1/3 of the amount of dried parsley as specified for the fresh parsley.

Variations

  • Use rainbow trout instead of salmon.
  • Add a tiny bit of dill in with the parsley, for an extra flavour note.
  • Cook in the air fryer instead. Simply add the salmon to a parchment-lined air fryer basket and cook at 375F for about 10 minutes, or until the salmon is opaque and flakes easily with a fork. 

Recipe tips!

The oven time will vary depending on the size and thickness of your salmon. If you have an instant-read thermometer, the fish will register 135F when it is done, or otherwise, when it flakes easily with a fork.

What to serve with garlic salmon

You could easily serve this salmon with just a green vegetable, such as green beans, broccoli or broccolini. If you’d like to add a starch to the plate, rice or cauliflower rice would be nice. My preferred pairing is orzo and green beans.

Tip! For quick and easy orzo, bring 2 cups of chicken broth to a boil in a small, non-stick skillet. (The larger surface area of a skillet cooks more quickly than a saucepan and a non-stick skillet prevents sticking and scorching.) Add 1/2 cup of orzo and boil until all the liquid is absorbed, about 8-10 minutes. Stir regularly towards the end of cooking. Finish with a pat of butter and some freshly ground pepper.

  • Remove from oven. Transfer salmon to a plate or plates. (The salmon should separate easily from the skin, so you can leave the skin behind on the baking pan). Top the salmon with some grated lemon zest, a bit of flaky salt and a scattering of chopped fresh parsley.
  • This salmon is lovely served with rice or orzo and a green vegetable.

Notes

Note 1: You can start with any cut of fresh salmon, skin-on or skinless. The amount is just a rough suggestion, so you can use a bit more or less, as you like. I’ve used a large, skin-on fillet here, but you can also use 4 individual, centre-cut salmon fillets. You can also substitute rainbow trout for the salmon.
Tip! You can also start with frozen salmon, but you will want to defrost it thoroughly first. You can defrost frozen salmon quickly by placing it in a plastic bag, and then submerging it in a large bowl of cold water.
Cook in the air fryer instead! Simply add the salmon to a parchment-lined air fryer basket and cook at 375F for 10 minutes, or until the salmon is opaque and flakes easily with a fork.
