Love a super simple, but flavorful 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 a few ingredients.
I love baked salmon recipes that only require simple ingredients and only take about 15-20 minutes of my time, such as my Garlic Butter Salmon in Foil, my Salmon Steak, my Baked Salmon recipe, my Broiled Salmon Recipe, and my Spicy Butter Salmon in Foil.
These recipes are all super easy to make, fresh, and flavorful. Perfect for a busy weeknight dinner.
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, just like my Easy Dijon Chicken Thighs Recipe.
Plus, by keeping the skin on, the fish comes out perfectly tender and moist.
Having a super-easy salmon recipe is essential for me since we eat baked salmon at least once a week.
It’s a great protein to consume, full of good fats, it’s fairly affordable, and tastes delicious too.
This Dijon Mustard Salmon will be your family’s favorite 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.
The other good thing about this recipe is that you don’t need parchment paper or a baking sheet to make it. Just use your good cast-iron skillet.
- Salmon fillets: choose fillets with the skin on. If possible, use wild salmon instead of farmed for fewer calories and higher mineral content.
- Lemon: you just need a few slices of lemon
- Olive oil: You can also swap for a neutral oil of your choice, like avocado oil.
- Dijon mustard: this gives a nice tang to the salmon.
- Lemon juice: I recommend using freshly squeezed lemon and not bottled lemon juice.
- Garlic: press the garlic or mince it.
- Fresh parsley: use chopped parsley or a fresh herb of your choice.
- Salt and pepper: you need just a touch!

- 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.
To store any leftovers, 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. You can add some butter or olive oil for some added moisture when reheating.
What should I serve with this recipe?
- Cauliflower rice or mashed cauliflower
- Roasted vegetables
- Green salad
- Roasted potatoes
- Broccoli salad
- Garlic Butter Sautéed Zucchini
- Couscous salad
- Spaghetti squash or zucchini noodles
- Spicy Roasted Cauliflower Recipe
I can’t stress enough about “don’t overcook your salmon”. In my opinion, overcooked 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 the salmon flakes easily with a fork.
If you have leftover salmon and want to change things up, here are some ways to enjoy the salmon:
- salmon tacos: shred the salmon up and use it as a taco filling.
- salmon pasta: roughly chop up the salmon and add it to a pasta or pasta salad.
- salmon salad: break up the salmon and toss it in a leafy salad or greek salad.
- salmon fried rice: break up the salmon and toss it in some fried rice

Dijon Mustard Salmon Recipe
Video
Ingredients
- 4 medium salmon fillets
- 1 tbsp fresh parsley chopped
- 1 tbsp lemon juice
- 4 tbsp olive oil
- 2 garlic cloves minced
- 1/2 tbsp Dijon mustard
- ¼ teaspoon onion powder
- Salt and black pepper to taste
- Slices of lemon for garnishing
Instructions
- Preheat the oven at 450F. In a small bowl add all the ingredients (except the salmon and the slices of lemon) and mix everything well until combined.
- Place the 4 salmon filets (skin side down) on a cast iron skillet. Add the Dijon mixture on top and sides of the salmon filets.
- Bake at 450°F for 10 minutes (the time will depend on the size of your salmon fillet). Garnish with lemon on top. Serve with cauliflower rice, green beans, roasted asparagus or mashed cauliflower.
Notes
- Make sure the pat dry the salmon before cooking so you get a nice sear.
- Keep the skin on the salmon so it’s easier to flip.
- If you do not have a cast-iron skillet, you can use a non-stick skillet and transfer to a baking sheet to bake in the oven.
- To store: Store leftover salmon in the fridge in an airtight container for up to 4 days.
- To reheat: You can reheat salmon on the stovetop or microwave or eat it chilled.
- To freeze: Freeze in a freezer-safe bag once the salmon fillets have reached room temperature. Freeze for up to 4 months.

We liked this a lot. I usually like maple or honey with dijon mustard but somehow following this I liked this just as well, without any “sweet” added. Didn’t use olive oil and it was fine without it. Wonderful would make often. Did sheet pan broccoli, carrots, peppers and roasted chickpeas with it. Nothing left!
Wow that’s awesome. Love your dish dish! Great idea!
Delicious! Yummy 🙂 Quick, simple and very tasty! thanks a lot!
Awesome!
This turned out really well. I didn’t have fresh garlic so I used granulated. Thank you for the recipe!
Awesome. Happy ou liked it!
I love it! I use it whenever we have salmon-which is every week!
How awesome! Happy to hear that 😉
Why is it advised to use a non-stick skillet, if you do not have cast iron skillet?, If you’re going to transfer it to a baking sheet to bake in the oven? Did I miss a step? Thanks!
Thanks much, Olivia, this was great! Will definitely make it again. I put some Good Seasonings Italian on the salmon for 2 hours before baking it. Juicy and delicious!
Awesome! Happy to hear that 😉
