Five ingredients. Twenty minutes. One pan. This is the recipe I pull out when I have nothing left in me after a long day but I still want to put something real on the table.

The glaze has three components: maple syrup (sweetness), Dijon mustard (tang, depth), and garlic (everything). The fourth and fifth ingredients are the salmon and a pinch of salt. That’s genuinely it.

Why it works

Salmon is forgiving. The glaze caramelizes quickly in a hot oven and forms a lacquered crust that keeps the fish moist underneath. The mustard’s acidity cuts the richness of the salmon perfectly. Kids who claim to hate fish eat this. I’ve seen it happen.

The only rule: don’t overcook it. Salmon at 125-130°F internal is silky and just barely opaque in the center. At 145°F (the FDA recommendation), it’s chalky. We shoot for 130°F and it’s flawless.

Ingredients

  • 4 salmon fillets (6 oz each), skin on or off
  • 3 tablespoons pure maple syrup
  • 2 tablespoons Dijon mustard (check label — most are GF, but verify)
  • 2 garlic cloves, grated
  • 1/2 teaspoon fine sea salt
  • Optional: fresh thyme or dill to finish

Instructions

  1. Preheat. Heat oven to 400°F (200°C). Line a small baking sheet or oven-safe skillet with foil.

  2. Make the glaze. Whisk together maple syrup, Dijon, and grated garlic in a small bowl.

  3. Season and glaze. Place salmon fillets on prepared pan. Season lightly with salt. Spoon glaze generously over each fillet — don’t be shy.

  4. Roast. Bake 12-15 minutes, depending on thickness (1-inch fillet = about 12 min). The glaze should be bubbly and slightly caramelized, and the salmon should flake easily at the thickest part.

  5. Rest briefly. Let rest 2 minutes, then serve with fresh herbs if using.

Hannah’s note: Use a thin spatula to serve if the skin sticks. If you’re nervous about overcooking, pull at 12 minutes and check — it will carry-cook slightly on the hot pan.

Frequently asked questions

Is Dijon mustard gluten-free? Most Dijon mustards are made without wheat — check for the GF certification or “no wheat” note. Grey Poupon and Maille are typically safe. When in doubt, Annie’s Organic Dijon is certified GF.

Can I use honey instead of maple syrup? Yes, exact same amount. The flavor is slightly less complex but still excellent.

What do I serve with this? We love it with the Crispy Smashed Potatoes, roasted asparagus, or a simple green salad. The glaze is good over rice too.

Can I make this on the stovetop? Yes. Sear skin-side down in an ovenproof skillet over medium-high heat for 3-4 minutes. Flip, add glaze, and finish on the stovetop over medium heat, basting, for 3-4 more minutes.

Can I use frozen salmon? Yes, thaw completely in the fridge overnight first. Pat completely dry before glazing.
