Start by slicing your potatoes, carrots, and shallots. Toss them with olive oil, paprika, salt, and pepper. Roast at 400°F for 30 minutes, flip, and continue for 10 more minutes until tender.
While the veggies bake, cut the salmon into 1-inch cubes. Mix it with olive oil, paprika, garlic powder, salt, pepper, Dijon mustard, and honey. Let it sit while the veggies finish roasting.
After 40 minutes, add the salmon cubes on top of the roasted veggies. Sprinkle with chopped parsley and bake for another 10–12 minutes. For extra browning, broil for the last 2 minutes.
Whisk together mayonnaise, Dijon mustard, honey, apple cider vinegar, paprika, and salt and pepper. Drizzle over the salmon and veggies just before serving.
