Dijon Baked Salmon Recipe
Ingredients
Instructions
- Pat salmon dry and season
Use paper towels to thoroughly dry the salmon fillets, then rub both sides with salt and pepper to build a simple, even flavor base.
- Make the Dijon lemon sauce
In a small bowl, whisk together Dijon mustard, fresh lemon juice, lemon zest, olive oil, melted butter, and grated garlic until glossy and smooth.
- Score the salmon skin
Lay the fillets skin side down and make two or three shallow diagonal cuts in the skin, which helps prevent curling and lets the sauce seep into the flesh.
- Spread the sauce onto the fillets
Place the salmon skin side up on a cutting board and spoon or brush a generous layer of the Dijon lemon mixture over the top, letting it coat evenly.
- Add cheese if using
Sprinkle the grated Parmesan or feta lightly over the sauce, pressing gently so it adheres and will turn into a delicate crust as it bakes.
- Bake until just cooked through
Transfer the fillets to a parchment lined baking sheet and bake at 400°F for 12 to 18 minutes, until the salmon flakes easily and the edges are golden.
- Let the salmon rest
Allow the fillets to sit for 3 to 5 minutes off the heat so the sauce sinks in and the interior stays juicy before serving.
- Taste and adjust
Check the seasoning with a quick squeeze of fresh lemon over the top and an extra pinch of salt or pepper if needed right before plating.
- Garnish and serve
Scatter with a little chopped fresh parsley or chives, if you like, and serve the salmon straight from the pan for the best flavor and texture.
Substitutions and variations
- Use gluten free Dijon mustard to make the recipe gluten free.
- Swap salmon for firm white fish like cod or sea bass if you prefer a milder flavor.
- Leave out the cheese for a dairy free version or use nutritional yeast for a vegan twist.
- Replace lemon juice with apple cider vinegar for a slightly tangier edge.
Chloe's tips
- For extra crisp on the edges, broil for the last 1 to 2 minutes, but watch closely to avoid overcooking.
- Keep the sauce loose rather than thick so it spoons evenly over the fillets and bakes into a glossy finish.
- Use a kitchen scale or weigh the fillets if you can, since cook time changes with thickness.
- Line the baking sheet with foil or parchment to make cleanup quick and to prevent sticking.
How to store it
- Store leftover Dijon baked salmon in an airtight container in the refrigerator for up to 3 days.
- Reheat gently in a low oven or in a skillet with a splash of broth to keep the fish moist and tender.
- Avoid microwaving for long periods, which can dry out the delicate texture.
Serving suggestions
Serve this quick weeknight dinner with simple sides that soak up the lemony sauce beautifully.
- Steamed green beans or roasted asparagus
- Creamy mashed potatoes or buttered egg noodles
- A crisp side salad with a light vinaigrette
Frequently asked questions
Can I bake the salmon without the skin
Yes, you can bake salmon without the skin, but brushing the fillet with a little oil and being gentle when you flip will help keep it from sticking and drying out.
What if I do not have Dijon mustard on hand
A mild yellow mustard mixed with a squeeze of lemon will work in a pinch, though the flavor will be a bit less tangy and complex.
How do I know when the salmon is perfectly cooked
The salmon is done when it flakes easily with a fork, looks opaque and moist, and an instant read thermometer inserted into the thickest part registers around 145°F.
Can I make this in the air fryer
Yes, you can air fry the salmon at 375°F for 10 to 14 minutes, brushing with sauce halfway through, for a nicely crisped top and tender interior.
