Can I use pre-prepared horseradish from a jar instead of fresh?

Yes, you can use jarred prepared horseradish to save time. While fresh horseradish has a more potent and lively flavor, the jarred variety still gives your salmon that essential tangy heat, making this dish even quicker to throw together.

What if I don’t have a broiler?

No broiler? No problem! Roast the salmon in a hot oven (425°F) for about 12-14 minutes instead. The crust won’t brown quite as much, but you’ll get the same tender, delicious fish.

Is this dish very spicy?

Fresh horseradish does have a pleasant heat, similar to a mild wasabi, but it’s not overwhelming. The mustard and butter mellow the sharpness. If you prefer a milder version, simply reduce the horseradish amount in the topping.

How can I tell when the salmon is fully cooked?

The best way is to check the thickest part of a fillet—it should flake easily with a fork and be just opaque throughout. A thermometer reading at 170ºF ensures it’s perfectly done without being dry.

Instructions

Prepare the Horseradish: Add the peeled and diced horseradish root and water to a food processor. Pulse until the horseradish is finely ground, taking care not to inhale the pungent fumes. Add in the sea salt and white vinegar, then pulse again until well combined. Transfer the prepared horseradish to a container for later use.
Preheat Broiler and Prepare Salmon: Set your oven broiler to 500°F and place the salmon fillets on a sheet pan lined with parchment or foil for easy cleanup.
Make the Horseradish Topping: In a bowl, combine 1-1/2 cups of the prepared horseradish with the melted butter or ghee, Dijon mustard, fine sea salt, freshly ground black pepper, and garlic powder. Mix well until the ingredients are thoroughly blended.
Top the Salmon: Evenly spread the horseradish mixture over the tops of the salmon fillets, pressing it gently into the fish to adhere.
Broil the Salmon: Place the sheet pan under the broiler and cook for 7-9 minutes, or until the salmon is cooked through (internal temperature should reach 170ºF) and the horseradish topping is lightly browned and crisp.
Garnish and Serve: Remove the salmon from the oven and sprinkle with minced parsley. Add a squeeze of fresh lemon over the top before serving. Enjoy with your favorite side dish.

Notes

You may have leftover horseradish; keep it covered in a container in the refrigerator for up to 2 weeks.
Adjust the amount of horseradish to your heat preference.
For a lighter option, use olive oil instead of butter or ghee.
Great served with roasted vegetables, steamed greens, or a light salad.
