• ½ teaspoon ground pepper, divided: Adds gentle heat and depth in every bite.

• 2 tablespoons melted butter: Gives the salmon a luscious finish and helps the mustard glaze stick beautifully.
• 1 tablespoon lemon juice: Brightens the dish with a fresh zing that cuts through the richness.
• 2 cloves garlic, minced: Garlic adds a fragrant depth that lingers in the background for irresistible flavor.
• 1¼ pounds salmon fillet, skinned and cut into 4 portions: Fresh salmon is the star here—juicy and tender, it bakes quickly for a perfectly flaky main course.

How to Make Easy Mustard Baked Salmon and Asparagus Recipe

Step 1: Prepare the Potatoes

Start by preheating your oven to 425°F (220°C). Toss the halved baby Yukon Gold potatoes with 1 tablespoon of the olive oil, half the salt, and half the pepper. Spread them out evenly on a baking sheet, making sure they have some room to crisp up rather than steam. These will roast first to develop a golden, crispy exterior, giving the dish that satisfying bite to compliment the salmon later.

Step 2: Make the Mustard Glaze

While the potatoes start roasting, whisk together the melted butter, lemon juice, and minced garlic in a small bowl. Then stir in 2 tablespoons of olive oil and a pinch of salt and pepper. This mixture will not only keep the salmon moist but also form the tangy, savory glaze that defines this Easy Mustard Baked Salmon and Asparagus Recipe.

Step 3: Add Salmon and Asparagus to the Pan

After the potatoes have roasted for about 20 minutes, take the baking sheet out and gently push the potatoes to one side. Lay the salmon fillets skin-side down on the open space and arrange the trimmed asparagus next to them. Brush the mustard glaze generously over each salmon portion, making sure every bite has that luscious coating.

Step 4: Bake Until Perfectly Cooked

Return the baking sheet to the oven and roast everything together for another 12 to 15 minutes. The salmon will turn opaque and flake easily with a fork when done, while the asparagus becomes tender but still crisp. This finishing step merges all the flavors in one pan, cutting down cleanup and keeping things simple but spectacular.

How to Serve Easy Mustard Baked Salmon and Asparagus Recipe

Garnishes

Sprinkling freshly chopped parsley over the salmon and asparagus adds a lovely, fresh herbal note that lifts the whole dish and makes it look irresistibly bright and inviting. It’s a simple final touch that transforms your plate from everyday to special with almost zero effort.

Side Dishes

This dish is so satisfying on its own, but if you want to take it up a notch, consider serving it with a light green salad dressed in lemon vinaigrette or some warm crusty bread to soak up any extra glaze and roasted juices. These sides keep the meal balanced without overshadowing the star of the show.

Creative Ways to Present

For a fun twist, serve the salmon portions over a bed of steamed quinoa or couscous to add a nutty texture and extra heartiness. You can also plate the asparagus spears fanned out gracefully beside the salmon for an elegant touch that’s perfect for guests or date night dinners.

Make Ahead and Storage

Storing Leftovers

Any leftover salmon and asparagus can be stored in an airtight container in the refrigerator for up to 2 days. Make sure to cool the food completely before refrigerating to maintain texture and freshness.

Freezing

While it’s best enjoyed fresh, you can freeze leftover salmon by wrapping it tightly in plastic wrap and then placing it in a freezer-safe bag. It will keep well for up to one month. Roasted asparagus is less freezer-friendly, as it can become watery after thawing, so it’s better to enjoy the salmon alone if freezing.

Reheating

To reheat, gently warm the salmon in a low oven (around 300°F or 150°C) for 10-15 minutes to keep it tender and juicy. Avoid microwaving if possible, as that can dry it out. If you have leftover asparagus, briefly sauté it on the stovetop to refresh its texture.

FAQs

Can I use frozen salmon for this recipe?

Yes, you can! Just make sure to thaw it completely and pat it dry before baking to ensure the glaze adheres well and the salmon cooks evenly.

Is it okay to substitute the asparagus with another vegetable?

Absolutely! Green beans, broccolini, or even Brussels sprouts would be lovely alternatives that roast nicely alongside the salmon.

How do I know when the salmon is perfectly cooked?

Look for opaque flesh that flakes easily with a fork but is still moist inside. Overcooked salmon becomes tough and dry, so keep an eye on the timer.

Can I make this recipe gluten-free?

Yes! All the ingredients in this Easy Mustard Baked Salmon and Asparagus Recipe are naturally gluten-free, making it perfect for gluten-sensitive eaters.

What can I add to the mustard glaze to spice it up?

If you like a bit of heat, a teaspoon of Dijon mustard mixed with a pinch of red pepper flakes or smoked paprika can elevate the glaze with a gentle kick.
