Ingredients You’ll Need

• Fresh Horseradish Root: The star of the show! Provides that distinctive peppery bite that makes this dish unique. Fresh is absolutely worth seeking out for its bright, clean flavor.
• White Vinegar: Helps preserve the horseradish and balances its natural heat with a touch of acidity.
• Wild-Caught Salmon Fillets: Choose thick, center-cut pieces for the best texture. Wild-caught has superior flavor and nutrition compared to farmed.
• Butter or Ghee: Creates richness and helps the horseradish topping become beautifully golden under the broiler. Ghee adds a lovely nutty quality if you have it.
• Dijon Mustard: Works with the horseradish to create a complex, spicy crust and helps bind the topping together.
• Seasonings (Salt, Pepper, Garlic Powder): The classic trio that enhances without competing with the main flavors.
• Fresh Parsley: Adds a pop of color and fresh herbaceous notes that brighten the finished dish.
• Fresh Lemon: That final squeeze cuts through the richness and makes all the flavors sing.

How to Make Horseradish Salmon

Step 1: Prepare the Horseradish

Add peeled and diced horseradish root and water to a food processor. Pulse until finely ground, being careful not to directly inhale the potent fumes (they can be quite strong!). Add salt and vinegar, then pulse until thoroughly combined. Transfer the freshly processed horseradish to a container.

Step 2: Prepare the Salmon

Preheat your broiler to 500°F and position the rack about 6 inches from the heat source. Place the salmon fillets on a sheet pan lined with foil or parchment for easier cleanup.

Step 3: Create the Topping

In a bowl, combine 1-½ cups of your freshly prepared horseradish with melted butter, Dijon mustard, salt, pepper, and garlic powder. Mix thoroughly until you have a consistent paste-like texture.

Step 4: Top the Salmon

Carefully spread the horseradish mixture evenly across the top of each salmon fillet, creating a generous layer that will become crispy during cooking.

Step 5: Broil to Perfection

Broil the salmon on high for 7-9 minutes. The fish is done when it reaches an internal temperature of 170ºF and the horseradish topping turns beautifully browned and crispy on the edges.

Step 6: Garnish and Serve

Sprinkle with freshly chopped parsley and give each fillet a generous squeeze of fresh lemon juice just before serving to brighten all the flavors.

Pro Tips for Making the Recipe

• Fresh is Best: While prepared horseradish can work in a pinch, the flavor of freshly grated horseradish is incomparable – it’s worth the extra few minutes.
• Don’t Overcook: Salmon can quickly go from perfect to dry. Start checking at the 7-minute mark, especially if your fillets are on the thinner side.
• Even Thickness: Try to select salmon fillets of similar thickness so they cook at the same rate.
• Prep Ahead: Make the horseradish mixture earlier in the day and keep it refrigerated until you’re ready to cook – the flavors will actually develop nicely with a little time.
• Room Temperature Salmon: Let the salmon sit at room temperature for 15 minutes before cooking for more even results.

How to Serve

This spectacular horseradish salmon pairs beautifully with a variety of sides to create a complete meal:

Simple Accompaniments

Serve with roasted asparagus, steamed green beans, or a light cucumber salad to balance the richness of the salmon.

Starchy Sides

Creamy mashed potatoes, wild rice pilaf, or crispy roasted fingerling potatoes make excellent partners.

Wine Pairings

A crisp Sauvignon Blanc or lightly oaked Chardonnay complements the horseradish spice perfectly.

Presentation

For a restaurant-quality presentation, serve each fillet on a warmed plate with the vegetable side, a lemon wedge, and perhaps a small dollop of additional horseradish for those who enjoy extra heat.

Make Ahead and Storage

Storing Leftovers

Store any leftover salmon in an airtight container in the refrigerator for up to 2 days. The horseradish flavor will actually deepen slightly overnight.

Freezing

While technically possible, freezing isn’t recommended as it can affect the texture of both the salmon and the horseradish topping.

Reheating

For the best results when reheating, warm gently in a 275°F oven until just heated through (about 10 minutes). Avoid microwaving, which can make the salmon rubbery.

Horseradish Storage

The freshly made horseradish will keep in a covered container in the refrigerator for up to 2 weeks – use it on sandwiches, with roast beef, or mix into creamy dressings for a zippy kick.

FAQs

Can I use prepared horseradish instead of fresh?
Yes, you can substitute about 3/4 cup of prepared horseradish for the fresh version in this recipe. Just drain it well and skip the food processor steps. The flavor won’t be quite as vibrant, but it’s a good time-saving option when needed.

How do I know when the salmon is perfectly cooked?
The salmon should flake easily with a fork but still maintain some translucence in the center. If you have a meat thermometer, aim for 145°F for medium doneness. Remember that the fish will continue cooking slightly after you remove it from the heat.

Can I make this recipe dairy-free?
Absolutely! Substitute the butter with olive oil or a good quality dairy-free butter alternative. The topping won’t brown quite as richly, but the flavor will still be excellent.

Is this recipe keto-friendly?
Yes! This horseradish salmon is perfect for keto diets as it’s naturally low in carbs and high in healthy fats. Just be sure to serve it with keto-friendly sides like cauliflower mash or roasted Brussels sprouts.
