Ingredients for Oven Roasted Salmon With Vegetables

Here are the ingredients you’ll need to make this salmon dish at home:

• Salmon: I vastly prefer wild-caught salmon over farmed salmon because it has a better nutritional profile, is more sustainable, and tastes much better. Salmon is one of my favorite protein options! If you haven't cooked it before, I've put together an entire salmon guide for you.
• Sweet Potatoes: Sweet potatoes provide your carbs and a perfect flavor that blends the entire rest of the dish together to make it one delicious cohesive meal.
• Asparagus: Asparagus cooks quickly and nutritionally rounds out the dish. Plus, its flavor pairs really well with the salmon, sweet potatoes, and seasonings.
• Dijon Mustard: Dijon mustard adds the perfect tangy flavor and helps keep the salmon tender.
• Lemon Juice: No fish dish would be complete without lemon juice!
• Seasoning: Garlic, dill, and other classic fish spices complete the flavor palette.

Recipe Tips And Ideas For Roasted Salmon and Sweet Potatoes

No matter how much you love a dish, sometimes you just want to change it up a little for variety.

Here are some ideas:

• Substitute baby red potatoes with green beans instead of sweet potatoes and asparagus.
• Zucchini with tomatoes would pair nicely with the dijon lemon salmon.
• I have also served this dish with roasted green beans, sugar snap peas, butternut squash, cabbage, bok choy, and tons of other veggies straight from my garden.

Note: When you change the veggies, make sure to adjust the cooking time if needed. You can always put the veggies in early to make sure you don't end up overcooking the salmon.

Seasoning Options

The seasonings, spices, and herbs in this roasted salmon recipe aren’t set in stone either. If you don’t like dill or don’t have any on hand, feel free to experiment with other herbs or just go with the garlic and oregano alone.

You can also get creative and customize this dish with your family’s favorite flavors! I highly recommend trying it out with a little honey in the sauce if your taste buds crave a contrast to the spicy, mustard-based sauce.

Frequently Asked Questions About Sheet Pan Roasted Salmon

Here are some questions I frequently get asked about by some readers...

Are sweet potatoes good for you?

Yes! Sweet potatoes tend to get a bad reputation, but they’re packed with good-for-you nutrients and vitamins.

Sweet potatoes are a good source of iron, B vitamins, calcium, selenium, and vitamin C. They’re also high in fiber and an antioxidant called beta-carotene. They're a great complex carbohydrate side dish (or main course base) that will keep you feeling full for a long time.

Still not convinced? Take a look at this resource post I put together on why you should eat more sweet potatoes!

Do I have to use dijon mustard?

No, you don't. You can swap it out for regular mustard if you like.

Since the flavor of Dijon mustard is sharper, stronger, and spicier than the typical yellow mustard, substituting one for the other will significantly change the flavor of this baked salmon recipe.

Instead, if you want to experiment with different mustards, give whole grain mustard a try because, like dijon, it starts with darker, spicier seeds and usually uses wine as its other main ingredient. Just keep in mind your salmon sauce will have some extra texture thanks to the whole mustard seeds.

Either way, it will produce a delicious dinner!

How can you tell if the roasted salmon is done?

Salmon will turn from red (or dark pink) and translucent to pink and opaque as it cooks. The easiest way is to gently press down on the top of the fillet with a fork. If the flesh flakes (separates along the lines that run across the filet) but is still a little red in the middle, it’s done cooking.

How do I make sure everything is done cooking at the same time?

The key to making sure this baked salmon dish turns out perfectly at the same time as the potatoes is to slice the potatoes nice and thin using a sharp knife or mandolin.

In addition, be sure to cut each slice as close to the same thickness as possible. (If you aren’t sure how thick your slices should be, check out the video below.) Since potatoes normally take a long time to cook, slicing them thinly and evenly cuts the cooking time down substantially.

Besides, who doesn't love a good oven chip?

What do I do if my fish is cooking faster than my potatoes?

If you find that your potatoes just aren't cooking quickly enough, I recommend removing the fish from the sheet pan just before it’s ready and tenting it with some foil while the potatoes finish cooking.

The lemon dijon salmon will finish cooking under the foil (and stay warm) which ensures that nothing will be overcooked (or undercooked!). This shouldn't be necessary if the potatoes are nice and thin, but it's a good back up just in case.
