Ingredients for sheet pan salmon including butternut squash, salmon, green beans, herbs, and spices.

Key Ingredients

To make this delicious dish, you will need the following key ingredients:

  • Salmon: I prefer to use fresh wild-caught salmon over the farm-raised kind, as it’s known to be more nutrient-rich. However, both are good options so use whichever you can.
  • Butternut squash: You could swap this out for another hearty squash like acorn squash or kabocha squash, or use sweet potatoes instead.
  • Green beans: These tasty veggies are packed with nutrients and delicious flavors. If you aren’t a fan, you can swap it out for another green veggie like broccoli or asparagus.
  • Dijon mustard: This tangy mustard is the base of the mustard sauce we will be spreading onto the salmon and packs a ton of great flavor.
  • Lemon juice: The acidity in the lemon juice brightens up the rest of the ingredients in the dish.
  • Garlic: I recommend using fresh garlic if you can for the most flavor, but garlic powder can be used in a pinch if needed.
  • Herbs and spices: We will be seasoning this dish simply with a flavorful combination of fresh dill, dried oregano, salt, and pepper.

Wild-Caught Salmon vs. Farm-Raised Salmon

The main difference between wild-caught salmon and farm-raised salmon is that wild-caught salmon live freely and eat organisms found in their natural environment, while farm-raised salmon are fed a processed diet of high-protein feed to fatten them up. As with any animal, the food it eats directly affects the level of nutrition it provides.

Wild-caught salmon is lower in calories and fat, while also being higher in beneficial minerals like zinc and iron. Farm-raised salmon, on the other hand, is higher in omega-3 fatty acids and vitamin C. While both types of salmon are healthy sources of protein, some people prefer wild-caught salmon because it’s leaner and cleaner. However, it’s typically also a bit more expensive. No matter which type of salmon you choose, it’s still an incredibly nutritious lean source of protein.

What to Serve With This Dish

This dish can be served on its own as a complete meal, but if you’re serving it at a dinner party or any kind of social gathering with a large group, you may want to pair it with some tasty sides. These are some of my favorite side dishes for this healthy salmon recipe:

Recipe Variations

Here are some of my favorite ways to switch up this healthy sheet pan recipe:

  • Swap out the protein: If you want to try out a different protein source, you can use chicken breasts, chicken thighs, or a different variation of firm flaky fish like cod or halibut.
  • Change up the starch: Not a fan of butternut squash? No problem. You can try a different type of squash like acorn squash, kabocha squash, or delicata squash. You could also use baby potatoes or sweet potatoes instead.
  • Add cheese: For a cheesy twist, sprinkle some shredded or grated parmesan cheese on top of everything after you’ve baked it.
  • Add garnishes: For a pop of color and added flavor, garnish with bright ingredients like fresh dill, fresh parsley, or green onions.
  • Switch up the seasonings: Instead of coating the salmon with a tangy mustard sauce, you can season it with a spice blend like Italian seasoning or Cajun seasoning for a different flavor profile.

How to Store This Dish

I would recommend storing the salmon separately from the veggies. Make sure to transfer everything in airtight bags or containers before putting them away. The salmon can be stored in the fridge for up to 3 days or in the freezer for up to 6 months. The veggies can be stored in the fridge for up to a week or in the freezer for up to 6 months.

Frequently Asked Questions

Below you will find answers to some of the most frequently asked questions about this dish:

How long can you store salmon in the fridge?

When stored properly in an airtight container, you can store cooked salmon in the fridge for up to 3 days.

Can I use a different sauce for the salmon?

Absolutely. If you want to switch it up, try making a sauce with butter, lemon juice, and fresh parsley. It’s absolutely delicious and works great with this recipe.

Can I freeze cooked salmon?

Yes. To store cooked salmon, make sure to let it cool down to room temperature first. Then, I recommend tightly wrapping each salmon filet in plastic wrap to ensure that no air can get in. Once you’ve done this, you can place them in an airtight bag or container and store the salmon fillets in the freezer for up to 6 months.

Could I make this with acorn squash? If I can would you recommend cubing it with the skin off or slicing it with the skin on.

Thanks!

Acorn squash would be delicious. You could it either way, but it would probably be easiest to cut the squash with the skin on into thin slices. It can be pretty difficult to peel raw acorn squash.
