Dijon Mustard Salmon Recipe

Love a super simple, but flavourful salmon recipe? Dijon mustard salmon is quick, easy, and full of flavor. Make this recipe tonight for a meal that goes from oven to table in just 15 minutes and it only requires few ingredients. 

I love baked salmon recipes that only require simples ingredients and only takes about 15-20 minutes of my time, such my Garlic Butter Salmon in Foil, my How to Cook Salmon in the Oven, my Foil Baked Salmon recipe, my Easy Broiled Salmon Recipe and my Spicy Butter Salmon in Foil.

These recipes are all super easy to make, healthy and flavourful. Perfect for a busy weeknight dinner meal.

So, this Dijon Mustard Salmon recipe is just as good as these 4 baked salmon recipes I mentioned before. So simple, so flavorful with Dijon mustard, garlic, fresh parsley, lemon juice and olive oil.

This Dijon Mustard Salmon Recipe is a great choice for busy weeknights. It cooks quickly and can be made with a variety of flavors.

This recipe uses a simple sauce made from pantry staples. The Dijon mustard adds a little bit of tang, while the fresh lemon creates an overall bright flavor.

Plus, by keeping the skin on, the fish comes out perfectly tender and moist.

Delicious Dijon Mustard Salmon

Having a super easy salmon recipe is essential for me since we eat baked salmon at least one time a week.

It’s a healthy protein to consume, full of great and healthy fats for your body and brain, it’s fairly affordable and tastes delicious too.

This Dijon Mustard Salmon will be your family favourite too and you know why? Because it’s loaded with super flavourful ingredients that you probably have in your pantry/kitchen. See, how can you go wrong with a recipe like that? Impossible even if you don’t have much experience in the kitchen.

How to make dijon mustard salmon

This recipe is so simple to make! Just pour a homemade sauce over the fish and bake until done.


  • Salmon fillets, skin on
  • Lemon, sliced


  • Olive oil
  • Dijon mustard
  • Lemon juice, freshly squeezed
  • Garlic, pressed
  • Fresh parsley, chopped
  • Salt and pepper

ingredients to make baked salmon with mustard sauce


  • First, mix together all of the sauce ingredients in a small bowl.
  • Add the salmon fillets to a cast iron skillet with the skin side down.
  • Then, pour the sauce over the top of the fillets. It’s okay if it runs over the side and collects in the pan.

  • Bake until the salmon is cooked all the way through. It should change in color to a light pink and will flake when pressed with a fork. Top with fresh lemon slices and serve with your preferred side dish.
NOTE: It’s perfectly safe to eat salmon skin, but you can remove it if you’d prefer. Either use a spatula to separate the meat from the skin before plating, or remove the meat with your fork as you eat.

Frequently asked questions

What can I use instead of a cast iron skillet?

You can make this recipe in any oven-safe skillet or on a baking sheet lined with aluminum foil.
Because cast iron holds heat better, you make need to increase the baking time by a few minutes if you use a different pan.

How do I store and reheat cooked salmon?

To store salmon, wrap tightly in foil or transfer to an airtight container. Keep in the refrigerator for up to 4 days.
Reheat in the oven at a low temperature so the fish doesn’t dry out. Place the salmon on a baking sheet and loosely cover with foil, then bake for about 15 minutes at 275 degrees F.

What should I serve with this recipe?

Because this dish has simple flavors, it goes with just about anything. Try serving it with:

How long do you cook salmon in the oven at 450?

I can’t stress enough about “don’t over cook your salmon”. In my option overcook salmon is just not good. It gets dry and it’s not flaky.

So, the baking time will depend on the size and the thickness of your salmon filet. If your filet is very thick I would say about 10 minutes in the oven at 450ºF. But it has a normal size I would say about 12 minutes or until salmon flakes easily with a fork.

What is the best seasoning for salmon?

This is another question that people keep ask a lot. I think salmon is one of those fishes that go really well with almost any type of spice you would like to use.

But my favourite is always garlic or garlic powder, Dijon mustard, lemon juice or lemon zest, lots of melted butter/ghee or olive oil, salt and black pepper, Italian seasoning and last but not least fresh parsley or dill. Mm… The best! Simply delicious!
