Mustard Salmon is a quick and easy entree that requires few ingredients and hardly any time to prepare. Make it to share with your loved ones, and/or as a meal prep recipe. This flavorful, nutritious baked salmon makes a healthy dinner recipe that’s ready in 30 minutes or less!

My love for salmon knows no bounds, and this is one of those recipes I make obsessively. 

I’m all about simple, convenient, cost-effective recipes, and I often forget to share the meals I make over and over, thinking they are far too boring.

Once my logic kicks in and it dawns on me everyone loves a simple, filling, delicious meal, I become ecstatic about sharing it.

So here we are, discussing this easy mustard salmon in its simple glory!

It requires two basic ingredients at a minimum: salmon and mustard. 

I toss some additional spices and oil in there for extra flavor to elevate this amazing main dish.

Let’s discuss the simple ingredients in further detail.

Ingredients for Mustard Salmon:

Fresh Salmon Filet: Pick up one pound of your favorite kind of salmon. I used King salmon for this recipe, which is my favorite wild-caught Alaskan salmon. Atlantic salmon, sockeye salmon, coho salmon and steelhead trout all work too!

Mustard: Pick your favorite type of mustard. Stone ground mustard is my favorite, but you can use whole grain mustard or Dijon mustard if that’s your preference. I don’t recommend yellow mustard due to its one dimensional flavor.

Avocado Oil: Adding richness to the fish and ensuring it bakes evenly, a little avocado oil forms a protective layer over the filet. I don’t recommend using olive oil because we’re baking at a high temperature and olive oil burns easily at high temperatures.

Seasonings: Paprika, garlic powder, dried parsley, and sea salt are our simple seasonings here. Add black pepper to your personal taste too.

Pure Maple Syrup (optional): For some optional sweetness to offset the tangy flavor, add a little pure maple syrup, brown sugar, or honey.

Recipe Adaptations:

• Swap the paprika and dried parsley with your favorite spices or dried herbs. Chili powder, garlic powder, cumin, fresh dill, Cajun seasoning, and dried oregano work great!
• Combine the mustard with 1 tablespoon of honey in a small bowl to make honey mustard salmon. Or, pure maple syrup for maple mustard salmon.
• Mix 1 teaspoon of fresh lemon zest and 1 tablespoon of fresh lemon juice with the mustard for a vibrant citrus vibe.
• Use more salmon and increase the amount of mustard and seasonings accordingly. Make this easy recipe for a large piece of salmon or many smaller salmon fillets.

This is how it all comes together.

How to Make Mustard Salmon:

Preheat the oven to 350 degrees F and lightly spray a large sheet pan or casserole dish with cooking oil.

Place the salmon fillet in the prepared baking sheet and brush lightly with avocado oil.

Sprinkle salmon with paprika, dried parsley and sea salt.

Pour the stone ground (or whole grain or Dijon) mustard on top of the salmon and spread with a knife or the back of a spoon until the flesh is evenly coated in mustard.

Bake on the center rack of the preheated oven 15-20 minutes, depending on the thickness of your salmon filet. Thinner fillets like sockeye salmon filets require less time (closer to 10-15 minutes), so be sure to spot check the internal temperature.

Switch the oven to the high broil setting and broil 5 minutes, or until salmon is crispy.

Salmon is cooked through when it reaches an internal temperature of 145 degrees Fahrenheit. Insert a digital thermometer into the the thickest part of the salmon filets to check for doneness.

Serve with lemon wedges and your favorite side dishes, and enjoy. I always recommend roasted or sauteed fresh seasonal veggies or a green salad.

Store leftover salmon in an airtight container in the refrigerator for up to 4 days.
