Tip

Trout and salmon may look similar, but they're two different species of fish. Steelhead trout live in saltwater seas and breed in freshwater rivers while rainbow trout spend their lives mostly or entirely in freshwater, per the National Wildlife Federation (NWF).

Salmon breed in freshwater streams and rivers, where the young grow up. As they reach adulthood, they move to saltwater oceans, per the NWF.

  1. Cook salmon in a skillet​ by heating a lightly oiled pan over medium-high heat for about 2 minutes. Add the salmon with its skin facing up and cook for about 5 to 6 minutes before flipping. Finish cooking with the skin down for about 4 to 5 minutes.
  2. Cook salmon in the oven​ by setting it on a baking sheet lined with aluminum foil and popping it in a 400 F oven for about 12 to 13 minutes.
  3. Cook salmon in an air fryer​ by spritzing thge basket with oil before adding the salmon and cooking it at 400 F for about 7 minutes.

Warning

To avoid foodborne illness, always cook fish until it reaches an internal temperature of 145 degrees Fahrenheit, per the USDA. You can check the temp using a food thermometer.

Step 4: Serve

Try serving the salmon alongside a starch, such as rice, and green vegetables.

Trout vs. Salmon: Which Is Healthier?

Both types of fish are nutritious, but there are several factors to think about when choosing between trout and salmon.

Source

In the U.S., salmon is farm-raised in either the Atlantic or the Pacific Oceans, but most of the salmon that's available is farmed rather than wild-caught, according to the Washington State Department of Health.

But wild salmon is still plenty available — you'll see it in many health-food stores sold fresh or frozen — and it's often caught in Alaska, according to Unity Point Health. Wild salmon is more nutritious because it has fewer calories and less saturated fat, according to the Cleveland Clinic.

Similarly, as much as 95 percent of rainbow trout is farm-raised, which makes it available throughout the year at reasonable prices, according to the Southern Regional Aquaculture Center.

If you're buying trout from the store, you can probably count on the fact that it came from either North Carolina or Idaho, as these two states are the most frequent producers, according to the North Carolina Cooperative.

Fat Content

Both salmon and trout are oily types of fish.

Salmon is a great source of omega-3 fatty acids, which are good not only for your heart but also for healthy vision and brain development, according to the Washington State Department of Health. Omega-3s can also help lower triglycerides levels and blood pressure, according to the Mayo Clinic.

A 3-ounce serving of cooked rainbow trout has about 143 calories and 6.3 grams of fat, according to the USDA. On the other hand, a 3-ounce serving of cooked wild Atlantic salmon has 155 calories and 6.9 grams of fat, per the USDA.

When fish have fairly high oil content already, they do well with cooking methods that don't rely on additional oils or fats. For example, you can bake, steam, grill or pan-fry either salmon or trout for a tasty meal.

Nutrients

Just as they have similar fat content, salmon and trout are similarly good additions to a healthy diet.

Rainbow trout is high in vitamin D and vitamin A while being low in sodium. It also gives you B vitamins, potassium, iron, phosphorus, copper, iodine, manganese, cobalt and selenium, according to the USDA.

As far as salmon goes, it's a great source of omega-3s, vitamin D, iron, calcium, potassium, phosphorus, magnesium, zinc and vitamin B12, according to the Washington State Department of Health.
