How to Make Maple Mustard Salmon with Crispy Potatoes

Step 1: Roast the Potatoes

Preheat the oven to 425°F (220°C).

Place the halved baby potatoes in a large bowl. Add the olive oil, garlic powder, dried thyme, paprika, salt and black pepper. Toss well until the potatoes are evenly coated.

Arrange the potatoes in a single layer on a baking sheet, placing them cut-side down. Roast for 25–30 minutes, or until they are golden brown and crisp on the outside.

Step 2: Make the Maple Mustard Glaze

While the potatoes are roasting, prepare the glaze. In a small bowl, whisk together the maple syrup, Dijon mustard, olive oil, fresh lemon juice, minced garlic, paprika, salt and black pepper.

Mix until the glaze is smooth and well combined.

Step 3: Prepare the Salmon

Pat the salmon fillets dry and set them aside.

Once the potatoes have started roasting, carefully remove the baking sheet from the oven. Make space for the salmon fillets alongside the potatoes.

Place the salmon on the baking sheet and brush each fillet generously with the maple mustard glaze.

Step 4: Bake the Salmon

Return the baking sheet to the oven and bake for 10–14 minutes, depending on the thickness of the salmon fillets, until the salmon flakes easily and is cooked through.

Brush the salmon with another layer of the maple mustard glaze halfway through cooking for an extra flavourful and glossy finish.

Step 5: Crisp Everything

For extra caramelisation, switch the oven to the grill/broiler for the final 1–2 minutes.

Watch the salmon carefully during this step because the maple glaze can caramelise quickly.

Step 6: Serve

Arrange the maple mustard salmon on serving plates alongside the crispy roasted potatoes.

Spoon any remaining pan juices over the salmon and potatoes. Finish with fresh chopped parsley, fresh thyme if using, and lemon wedges.

Serve immediately while the salmon is warm and the potatoes are crisp.

Helpful Tips

Cut the potatoes evenly: Similar-sized pieces help the potatoes cook at the same rate.
Keep the potatoes cut-side down: This helps create beautifully golden and crisp surfaces.
Dry the salmon first: Patting the fillets dry helps the glaze coat the surface evenly.
Watch the broiler: The maple syrup can caramelise quickly, so keep a close eye on the salmon during the final 1–2 minutes.
Adjust the cooking time: Thicker or thinner salmon fillets may need slightly more or less time in the oven.

Serving Suggestions

Serve with a simple green salad for a fresh side.
Add steamed green beans or roasted vegetables.
Serve with extra lemon wedges for a bright finish.
Pair with fresh herbs such as parsley or thyme.

Storage

Store leftover salmon and potatoes in airtight containers in the refrigerator. Reheat gently until warmed through, taking care not to overcook the salmon.

Frequently Asked Questions

Can I use another type of mustard?

Dijon mustard is used in this recipe to provide the characteristic tangy flavour of the glaze. For the intended flavour, Dijon mustard is the recommended choice.

Can I use regular potatoes instead of baby potatoes?

Yes. Regular potatoes can be used, but cut them into smaller, even pieces so they roast properly alongside the salmon.

Can I prepare the glaze ahead of time?

Yes. The maple mustard glaze can be mixed ahead of time and kept refrigerated until you’re ready to use it.

Why are my potatoes not crispy?

Make sure the potatoes are arranged in a single layer with enough space between them. Keeping them cut-side down also helps them develop a crisp, golden surface.

Can I skip the broiler step?

Absolutely. The broiler is optional and is included for extra caramelisation. The salmon will still be delicious without it.

What should I serve with maple mustard salmon?

Crispy potatoes are already included as the main side. A simple green salad, steamed green beans or roasted vegetables can also be served alongside the salmon.
