This baked Dijon salmon has become my absolute go-to recipe when I want something that tastes incredibly sophisticated and restaurant-quality but requires almost no actual cooking skills or complicated techniques. I started making this during one of those weeks when I was intimidated by cooking fish but wanted to serve something impressive for dinner guests. The first time I made it, I couldn't believe how that simple foil-packet method created perfectly tender, flaky salmon that was impossible to overcook. Now it's become my signature dish that I make whenever I want to feel like a competent cook while actually using the most foolproof method possible.
The secret to this recipe's success is that aluminum foil tent which traps steam and prevents the salmon from drying out, plus that incredible sauce made with olive oil, Dijon mustard, and warm spices. My husband always says this tastes like something from an expensive Mediterranean restaurant, and I love how the lemon and garlic make the whole kitchen smell amazing while it's baking. Even my kids enjoy picking off the crispy edges after broiling.
Ingredients You'll Need
- Salmon fillets: (4 pieces, 5 oz each, skin-on) - center-cut fillets cook most evenly
- Extra virgin olive oil: (1/4 cup plus extra for brushing) - use good quality for best flavor
- Fresh lemon: (1 large) - you'll need both zest and juice
- Dijon mustard: (1 1/2 teaspoons) - adds peppery complexity to the sauce
- Fresh garlic: (3 cloves, minced) - essential for building flavor depth
- Dried oregano: (1 teaspoon) - brings Mediterranean herb flavor
- Ground coriander: (1/2 teaspoon) - adds lovely fragrance that pairs beautifully with fish
- Sweet paprika: (1/2 teaspoon) - provides color and mild warmth
- Red pepper flakes: (1/2 teaspoon, optional) - adds gentle heat
- Kosher salt and black pepper: - for seasoning throughout
- Fresh dill: (2 tablespoons, chopped) - for garnish and freshness
Step-by-Step Instructions
- Prepare your oven and baking setup:
- Preheat oven to 375°F and position one rack in the center and another about 6 inches from the broiler. Line a large sheet pan with aluminum foil, leaving enough excess on one long side to fold over the salmon. Place parchment paper on top and brush lightly with olive oil.
- Season the salmon properly:
- Pat the salmon fillets completely dry with paper towels and place them skin-side down on the parchment. Season generously with salt and black pepper, using about 1/2 teaspoon of each. Proper seasoning is crucial for bringing out the fish's natural flavors.
- Create the flavorful Dijon sauce:
- In a small bowl, combine the olive oil, lemon zest, lemon juice, Dijon mustard, minced garlic, oregano, coriander, paprika, and red pepper flakes if using. Whisk everything together until well combined. The sauce should be aromatic and slightly thick.
- Coat the salmon thoroughly:
- Spoon the Dijon mixture over each salmon fillet, using your hands or a brush to rub it into the tops and sides of the fish. Make sure every surface is coated - this is what creates all that incredible flavor and helps keep the fish moist.
- Create the steam tent and bake:
- Fold the excess foil over the salmon, creating a tent that's high enough not to touch the fish. Crimp the edges tightly to seal completely - this traps the steam that gently cooks the salmon. Bake for 15-20 minutes until the fish is almost cooked through at the thickest part.
- Finish with broiling for golden edges:
- Carefully remove the pan and open the foil to expose the salmon. Move to the upper rack and broil on high for about 3 minutes until the top browns lightly and the edges get slightly crispy. Watch closely to prevent burning the garlic. Sprinkle with fresh dill and serve immediately with lemon wedges.

Mastering the Foil Packet Method
The foil tent is crucial - it should be sealed tightly around the edges but not touching the fish on top. This creates a steam environment that cooks the salmon gently and prevents it from drying out, which is the most common problem with baked fish.
Getting the Timing Right
Start checking at 15 minutes, especially for thinner fillets. The salmon is done when it flakes easily with a fork but is still slightly translucent in the very center - it will finish cooking from residual heat.
Understanding the Sauce Components
The combination of olive oil, Dijon mustard, and lemon creates both flavor and moisture. The coriander is particularly important - it's different from cilantro and adds a lovely fragrance that complements fish beautifully.
Achieving Perfect Browning
The broiling step at the end creates those golden, slightly caramelized edges that make the dish look restaurant-quality. Watch carefully during this step as it goes from perfect to burnt very quickly.
Storage and Reheating Tips
Leftover salmon keeps in the refrigerator for up to three days. Reheat gently in a low oven or enjoy cold in salads. The flavors actually develop more after sitting, making leftovers quite delicious.
I learned that trying to cook salmon without the foil tent usually results in dry, overcooked fish no matter how carefully I watched the timing. The steam-cooking method is what makes this recipe so foolproof and consistently delicious. My mother-in-law, who claims she can't cook fish, now makes this regularly because it's impossible to mess up.
