Introduction: A Tangy Twist on Salmon Night
I’ll let you in on a little secret: salmon night at my house used to be… well, predictable. A simple lemon wedge, a sprinkle of herbs, maybe a quick roast. Delicious? Sure. But memorable? Not really.
Then one chilly spring evening, while rummaging through the fridge, I found an almost-forgotten jar of fresh horseradish. On the shelf below: Dijon mustard. Suddenly, inspiration struck. I whipped up a creamy, fiery horseradish spread, slathered it over a beautiful salmon fillet, roasted it to perfection, and paired it with tangy, golden mustard potatoes.
The result? A dish so flavorful, bold, and comforting that it became a family favorite overnight. Now, whenever I make Horseradish Roasted Salmon With Mustard Potatoes, it feels like I’m serving something special — even on a busy Tuesday.
This recipe perfectly balances the heat of horseradish, the richness of salmon, and the tang of mustard. It’s elegant enough for guests but easy enough for a weeknight. Best of all, it’s ready in under an hour.
Let’s dive into the magic. ✨
📝 Ingredients

🐟 For the Salmon:
- 4 salmon fillets (about 6 oz each), skin-on or skinless

- 1 tbsp olive oil
- 1 garlic clove, finely minced
- Salt and pepper, to taste
- Fresh dill or parsley, for garnish (optional)

- 2 tbsp Dijon mustard
- 1 tbsp whole-grain mustard
- 2 tbsp olive oil
- 1 tbsp apple cider vinegar (or white wine vinegar)
- 1 tsp honey (optional, to balance the tang)
- Salt and pepper, to taste
- Fresh chives, chopped (optional)
🌿 Substitution & Variation Ideas:

👩🍳 Step-by-Step Instructions
This recipe may sound fancy, but it’s surprisingly straightforward. Here’s how to make Horseradish Roasted Salmon With Mustard Potatoes step by step.
🥔 Step 1: Roast the Potatoes
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
Halve the baby potatoes and toss them in olive oil, salt, and pepper. Spread them cut-side down on the sheet for maximum crispiness. Roast for 25–30 minutes, until golden and tender.
💡 Pro Tip: Starting the potatoes first gives them time to crisp up while you prepare the salmon topping.
🐟 Step 2: Prepare the Horseradish Topping
In a small bowl, mix together horseradish, sour cream, Dijon mustard, olive oil, and garlic. Season with a little salt and pepper. Taste and adjust — this is your flavor bomb, so make it sing!
🐠 Step 3: Roast the Salmon
Place the salmon fillets on a separate parchment-lined baking sheet. Pat them dry with paper towels to help the topping stick.
Spread the horseradish mixture evenly over the top of each fillet. Roast for 10–12 minutes, depending on the thickness of your salmon. You want the fish just opaque and flaky but still juicy inside.
💡 Pro Tip: If you love a golden crust, broil the salmon for the last 1–2 minutes — but watch it closely!
🥄 Step 4: Dress the Potatoes
Once the potatoes are roasted, transfer them to a large bowl. Whisk together Dijon mustard, whole-grain mustard, vinegar, honey, olive oil, salt, and pepper in a small bowl, then pour over the warm potatoes. Toss until fully coated.
The warm potatoes soak up the dressing beautifully, becoming tangy, flavorful, and slightly creamy.
🌿 Step 5: Serve and Enjoy
Plate the roasted salmon alongside the mustard potatoes. Garnish with fresh dill, parsley, or chives for a burst of green. Serve immediately, while everything is warm and fragrant.

🧊 Storage & Reheating
- Fridge: Store leftover salmon and potatoes separately in airtight containers for up to 3 days.
