Some nights, I want dinner to feel a little indulgent but without chaining myself to the stove, and that’s exactly where this baked salmon with roasted potatoes and asparagus comes in. It’s the kind of recipe that looks and tastes restaurant‑worthy, but in reality, the oven is doing all the work while I set the table or pour a glass of wine.
The salmon bakes until it’s irresistibly flaky, the baby potatoes soften inside while roasting into crispy golden bites, and the asparagus stays tender yet keeps its fresh, bright snap. And then, just when you thought it couldn’t get better, everything gets drizzled with a silky melted cheese sauce that takes this one‑pan dinner into comfort‑food heaven.
Why You’ll Love This Recipe
The beauty of this dish is its simplicity. One sheet pan, minimal prep, and almost no cleanup. In under an hour, you’ve got perfectly flaky salmon alongside crispy potatoes and tender asparagus, all tied together with that rich, creamy cheese drizzle. The cheese sauce gives a savoury finish without overwhelming the natural freshness of the salmon and veggies, just the right amount of indulgence.
It’s also endlessly adaptable, which is why it’s on repeat in my kitchen. Don’t have asparagus? Use green beans, zucchini, or broccoli. Craving something sweeter? Swap in sweet potatoes instead of baby reds. And if you want to play with flavour, try smoked paprika, a pinch of cayenne for heat, or even switch up the protein, trout and cod work beautifully too. It’s the kind of recipe that feels new each time you make it, depending on your mood and what’s in the fridge.
Ingredients
For the Salmon and Vegetables:
- 4 salmon fillets (about 6 oz each)
- 1 lb baby potatoes, halved
- 1 lb fresh asparagus, trimmed
- 3 tbsp olive oil
- 1 tsp smoked paprika
- 1 tsp garlic powder
- 1 tsp dried thyme
- Salt and black pepper, to taste
- Lemon wedges, for serving
For the Melted Cheese Sauce:
- 2 tbsp unsalted butter
- 2 tbsp all-purpose flour
- 1½ cups whole milk
- 1 cup shredded mozzarella cheese
- ½ cup shredded Parmesan cheese
- ½ tsp garlic powder
- ¼ tsp nutmeg (optional)
- Salt and black pepper, to taste
For Garnish (Optional):
- Fresh parsley, chopped
- Extra Parmesan cheese
Step-by-Step Instructions
1. Prep the Potatoes
Preheat the oven to 400°F (200°C). Toss halved baby potatoes with olive oil, smoked paprika, garlic powder, salt, and pepper. Spread them on a baking sheet and roast for 15 minutes to start softening and browning.
2. Add Salmon and Asparagus
Remove the tray from the oven. Push the potatoes to the sides, place salmon fillets in the center, and add asparagus around them. Drizzle everything with olive oil, season with thyme, salt, and pepper, then return the tray to the oven. Bake for another 12 to 15 minutes until salmon is flaky and potatoes are golden.
3. Make the Cheese Sauce
While everything bakes, melt butter in a saucepan over medium heat. Whisk in flour and cook for 1 minute to form a roux. Slowly add milk while whisking until smooth and slightly thickened. Stir in mozzarella, Parmesan, garlic powder, nutmeg, salt, and pepper. Simmer until creamy and silky.
4. Assemble and Serve
Remove the tray from the oven. Plate the salmon with roasted potatoes and asparagus. Drizzle melted cheese sauce generously over the top or serve it on the side. Garnish with fresh parsley, extra Parmesan, and lemon wedges. Serve hot.
