Maple Dijon Salmon with Roasted Potatoes brings a complete dinner together on one sheet pan. The salmon gets a glossy mustard glaze while baby potatoes turn crisp at the edges and green beans roast until tender. It’s simple, balanced, and easy enough for a regular weeknight.
Why Make This Recipe
This is the kind of salmon dinner I make when I want something that feels fresh but doesn’t require three separate pans. The potatoes start first, giving them time to brown before the salmon and green beans join them.
The glaze takes about two minutes to stir together. Maple syrup adds a little sweetness, Dijon mustard keeps it sharp, and lemon stops the sauce from tasting heavy. I use skin-on salmon when I can find it, but skinless fillets work just as well.
Salmon cooks quickly, so it helps to check it before the timer says it’s done. The thickest part should flake easily and reach 145°F, the safe internal temperature recommended by the USDA seafood safety guide.
How to Make Maple Dijon Salmon with Roasted Potatoes
Ingredients:
- 1 1/4 pounds salmon fillets, cut into 4 portions
- 1 pound baby Yukon Gold potatoes, halved
- 8 ounces fresh green beans, trimmed
- 2 tablespoons olive oil, divided
- 1/2 teaspoon kosher salt, plus more for the vegetables
- 1/4 teaspoon black pepper
- 2 tablespoons pure maple syrup
- 1 1/2 tablespoons Dijon mustard
- 1 tablespoon fresh lemon juice
- 1 small garlic clove, finely grated
- 1/2 teaspoon smoked paprika
- 1 tablespoon chopped fresh parsley, for serving
- Lemon wedges, for serving
Directions:
- Plan on 15 minutes of prep and 22 to 25 minutes of cooking time. This recipe serves 4. Heat the oven to 425°F and line a large rimmed sheet pan with parchment paper for easier cleanup.
- Place the halved potatoes on the pan. Toss them with 1 tablespoon of olive oil, 1/4 teaspoon salt, and the black pepper. Arrange them cut-side down, then roast for 15 minutes. Starting them alone gives the potatoes a head start and keeps the salmon from overcooking.
- While the potatoes roast, whisk the maple syrup, Dijon mustard, lemon juice, garlic, smoked paprika, and the remaining 1 tablespoon olive oil in a small bowl. The glaze should look smooth and slightly thick.
- Take the pan from the oven and push the potatoes to one side. Add the green beans, toss them with a small pinch of salt, and place the salmon fillets in the open space. Pat the salmon dry first so the glaze sticks instead of sliding off.
- Spoon the maple Dijon mixture over the salmon, using the back of the spoon to cover the tops. Roast for 10 to 12 minutes, depending on the thickness of the fillets. The salmon is ready when it flakes at the edges and the center reaches 145°F.
- Let the salmon rest on the pan for 3 minutes. Sprinkle the parsley over everything and serve with lemon wedges. The pan juices are good drizzled over the potatoes.
How to Serve Maple Dijon Salmon with Roasted Potatoes
This dinner already has protein, potatoes, and a green vegetable, so I don’t add much. A few lemon wedges and chopped parsley are enough. For a bigger meal, serve it with a crisp cucumber salad or a spoonful of plain Greek yogurt mixed with lemon zest.
Keep the salmon portions whole when serving. The glaze looks nicest that way, and you can spoon any extra juices from the pan over the top. For another easy seafood dinner, try the Seared Salmon with Lemon Orzo, which uses a skillet instead of the oven.
How to Store Maple Dijon Salmon with Roasted Potatoes
Cool leftovers promptly, then place the salmon and vegetables in separate airtight containers. Refrigerate them for up to 3 days. The FoodSafety.gov cold storage chart is a useful reference for cooked seafood and other leftovers.
Reheat the potatoes and green beans in a 375°F oven or air fryer until warm. Add the salmon for the last 4 to 5 minutes, just until heated through. The microwave works in a pinch, but use short 30-second intervals so the fish doesn’t turn dry.
Tips to Make Maple Dijon Salmon with Roasted Potatoes
- Choose salmon fillets that are similar in thickness. They will finish at about the same time.
- Don’t skip drying the salmon. Excess moisture makes the glaze run off and prevents the top from browning.
- Cut larger baby potatoes in quarters. Pieces should be close to 1 inch so they become tender in the first 15 minutes.
- Use real maple syrup rather than pancake syrup. The flavor is cleaner, and the glaze won’t taste overly sugary.
- Keep an eye on the glaze near the end. Maple syrup can darken quickly, especially on a hot sheet pan.
- For extra browning, switch the oven to broil for 1 minute after the salmon is cooked. Stay beside the oven because the glaze can scorch fast.
- Check the salmon in its thickest section with an instant-read thermometer. The FDA’s advice about eating fish also offers guidance for choosing and preparing seafood.
Variation
Make the same dinner with a garlic herb butter glaze. Replace the maple syrup and Dijon with 2 tablespoons softened butter, 1 tablespoon lemon juice, 1 minced garlic clove, and 1 teaspoon dried Italian seasoning. Spread it over the salmon before roasting, then finish with fresh dill or parsley.
You can also swap the green beans for asparagus, broccoli florets, or sliced zucchini. Add quick-cooking vegetables with the salmon, but give dense vegetables such as carrots or Brussels sprouts the same head start as the potatoes. For a skillet option with a sweeter sauce, the Brown Sugar Chili Salmon Dinner is a good direction.

Notes
FAQs
Can I use frozen salmon?
Yes. Thaw it completely in the refrigerator overnight, then pat it very dry before glazing. Frozen salmon releases extra moisture as it cooks, so roasting it from frozen can make the potatoes finish before the fish is ready.
How do I know when salmon is done?
The safest check is an instant-read thermometer inserted into the thickest part. It should read 145°F. Without a thermometer, look for flesh that flakes easily and is opaque around the edges with just a slightly moist center.
Can I prepare this salmon dinner ahead?
You can halve the potatoes, trim the beans, and mix the glaze earlier in the day. Keep everything covered in the refrigerator, but wait to season and glaze the salmon until just before roasting. That keeps the fish from becoming watery.
Conclusion
Maple Dijon Salmon with Roasted Potatoes is a dependable sheet pan dinner with very little fuss. The potatoes become crisp, the beans stay fresh-tasting, and the salmon gets a bright, lightly sweet glaze. Put the pan in the center of the table and let everyone add lemon to taste.
