Make a restaurant-quality salmon recipe in just 15 minutes from scratch. We love oven baked salmon, but grilled salmon is also delicious.

Salmon is one of our favorite proteins to prepare because it’s flavorful, healthy, and easy to cook. 

This is by far one of the best ways to enjoy salmon steaks. Pair with a side of roasted vegetables, and you’ll have a healthy dinner ready for those busy weeknights.

How To Choose The Right Salmon

You’re more likely to find a variety of salmon options at the grocery store, whether it’s wild or farmed, fresh, frozen, or smoked. Here are some tips on how to pick the greatest salmon: 

  • Fresh salmon should look bright and juicy, not brownish, and have a sea-like scent rather than a fishy one. 
  • Frozen salmon – If it’s vacuum-sealed and the label claims it was flash-frozen immediately after harvest, it can taste fresher than the fish behind the counter.

Ingredients For Grilled Salmon Steak 

You will need a few ingredients to make this delicious grilled salmon steaks recipe. Here is everything you need:

ingredients for grilled salmon steaks
  • Salmon Steaks – I recommend choosing wild caught salmon if possible. Look for salmon steaks that are bright in color and have a fresh, mild odor. If the fish has a strong, unpleasant fishy smell, it is likely, not fresh. If you’re using frozen salmon, allow it to defrost before grilling.
  • Olive Oil – for more flavor, replace the oil with grass-fed butter. Compound butter is also another way to add more taste to your fish.
  • Stone-Ground Mustard – this type of mustard adds texture and a different flavor to the sauce.
  • Greek Yogurt – the creamy base for the sauce that adds the right tangy flavor and creaminess.
  • Chives – finely chopped to add freshness to the dish.
  • Honey – you can use keto honey or sugar-free syrup to balance out the flavors.
  • Lemon Juice – add a bright, tangy taste to the sauce.
  • Salt&Pepper – to taste.

How To Cook Salmon Steaks

It’s super easy to grill salmon steaks once you gather all the ingredients. I chose to use a grill pan, but you can pan-sear the salmon steaks without sacrificing the taste. Let’s see how to make grilled salmon steaks: 

Prepare the salmon steaks – Pat dry the salmon steaks and place them aside on a plate. Season each salmon steak with salt and pepper.

    Tips For Making The Best Grilled Salmon Steaks

    • Be sure to pat dry the salmon steaks before placing them on the grill. If there’s too much moisture, it may stick to the grill.
    • The cooking time will depend on the thickness of the fillet. So make sure that you check the fish while grilling to prevent overcooking.

    • For even more flavor, you can marinate the salmon pieces.
    • You can add some shredded parmesan cheese to your sauce.

    Can I Make This Recipe Ahead Of Time?

    Sure. Cook the salmon, place it in an airtight container in the fridge, then make the sauce and store it until you want to use it (the longer this sauce stays in the fridge, the more delicious it will be).

    How To Serve

    When I first cooked this salmon, I ate it as simple as with the sauce because I was amazed by this delicious combination. But when I make it for my guests, I also make some side dishes that pair perfectly with this recipe:

    • You can serve it with some cauliflower mashed potatoes.
    • Roasted vegetables such as broccoli or zucchini.

    How Can I Store Salmon Steaks

    • Fridge: you can store the leftovers in the fridge in an airtight container for up to four days.
    • Freezer: if you have any leftovers and don’t plan to eat right away, you can store them in the freezer for up to two weeks.
