This easy coho salmon recipe pairs the fish’s mild flavor with a fast honey-garlic glaze made from lemon, Dijon mustard, and a splash of soy sauce. Baking at high heat keeps the fillets moist while caramelizing the glaze around the edges.
Coho—also called silver salmon—is leaner and milder than Chinook, so it cooks quickly and benefits from a light coating of oil. The complete dinner is ready in about 22 minutes.

Honey-Garlic Baked Coho Salmon
Ingredients
Instructions
- Heat the oven to 425°F. Line a rimmed baking sheet or shallow baking dish with parchment paper or lightly oil it.
- Pat the coho salmon dry. Place the fillets skin-side down with a little space between them and brush the tops lightly with olive oil.
- Whisk the honey, soy sauce, lemon juice, garlic, Dijon, smoked paprika, salt, and pepper in a small bowl until smooth.
- Spoon about two-thirds of the glaze over the salmon, coating the tops and sides. Reserve the remaining glaze in a clean bowl that has not touched raw fish.
- Bake for 8 minutes, then brush with the reserved glaze. Continue baking for 3 to 6 minutes, depending on thickness, until the center reaches 145°F and flakes easily with a fork.
- Rest for 2 minutes. Sprinkle with parsley or dill and serve with lemon wedges and the pan juices.

What Is Coho Salmon?
Coho salmon (Oncorhynchus kisutch) is a Pacific salmon also known as silver salmon. NOAA describes it as mild and delicate, with reddish-orange flesh that is generally paler than Chinook or sockeye. It becomes firm and flaky when cooked.
Fresh wild coho is most available from summer through late fall, while frozen fillets are sold year-round. U.S. wild-caught coho comes mainly from Alaska, with smaller harvests from Washington and Oregon.
Why This Recipe Works
- High heat: cooks the relatively lean fillets quickly before they dry out.
- Olive oil: adds richness and protects the surface.
- Honey: balances the savory soy sauce and caramelizes at the edges.
- Lemon and Dijon: brighten the mild fish without masking it.
- Two-stage glazing: builds flavor while keeping some glaze fresh and glossy.
How Long to Bake Coho Salmon
At 425°F, a 1-inch-thick coho fillet usually needs 11 to 14 minutes. Thin tail pieces may finish in 8 to 10 minutes. FoodSafety.gov recommends cooking fish to 145°F (63°C), or until the flesh is opaque and separates easily with a fork. Check the thickest part without touching the pan.
How to Avoid Dry Coho Salmon
- Choose similarly sized center-cut portions so they finish together.
- Thaw frozen fillets completely and pat them dry.
- Keep the skin on during cooking when possible.
- Brush lean coho lightly with oil.
- Start checking several minutes early; carryover heat continues after removal.
- Use an instant-read thermometer rather than relying only on color.
Skin-On vs. Skinless Fillets
Both work. Skin protects the fish from direct heat and makes the fillet easier to transfer. Bake skin-side down and slide a thin spatula between the flesh and skin when serving, or eat the skin if it has been crisped in a skillet.
Cooking Variations
Grilled Coho Salmon
Heat a clean, well-oiled grill to medium-high. Place skin-on fillets skin-side down, cover, and grill for 5 to 6 minutes. Brush with glaze, carefully turn, and cook 2 to 4 minutes more until the center reaches 145°F.
Skillet Coho Salmon
Heat 1 tablespoon oil in a nonstick or cast-iron skillet over medium-high. Cook skin-side down for 4 to 5 minutes, turn, reduce the heat to medium, and cook 2 to 4 minutes. Add the glaze during the final minute so it does not burn.
Air-Fryer Coho Salmon
Preheat to 390°F. Arrange glazed fillets in one layer and air-fry for 7 to 10 minutes, checking early if they are thin.
Foil-Packet Coho
Place each fillet on foil with glaze and a thin lemon slice. Seal loosely and bake at 400°F for 12 to 15 minutes. Open carefully because hot steam will escape.
Easy Flavor Variations
- Maple-Dijon: replace honey with pure maple syrup and add fresh thyme.
- Garlic butter: replace olive oil with melted butter and omit soy sauce.
- Teriyaki: use teriyaki sauce in place of soy and Dijon, then add grated ginger.
- Herb lemon: omit honey and soy; use extra lemon, parsley, dill, and chives.
- Spicy: add sriracha, red pepper flakes, or a pinch of cayenne.
Best Side Dishes
Serve coho salmon with roasted asparagus, green beans, broccoli, baby potatoes, rice, quinoa, couscous, or a crisp cucumber salad. The honey-garlic glaze also pairs well with sautéed bok choy or sesame noodles.
Coho vs. Chinook and Sockeye
- Coho: mild flavor, medium oil content, tender and versatile.
- Chinook: richer, fattier, and usually thicker; see our Chinook salmon recipe.
- Sockeye: deeper red color, firmer texture, and a more pronounced salmon flavor.
Fresh or Frozen Coho?
Either is excellent. Frozen-at-sea salmon can be very fresh tasting because it is processed soon after harvest. Thaw overnight in the refrigerator, or seal the fish in a leakproof bag and submerge it in cold water, changing the water every 30 minutes. Never thaw seafood on the counter.
Storage and Reheating
Refrigerate cooked salmon in a covered container within 2 hours and use within 3 to 4 days. Reheat gently in a covered 275°F oven until hot, or enjoy cold in salads and grain bowls. High microwave heat can dry the fish.
Frequently Asked Questions
Does coho salmon taste fishy?
Fresh coho has a mild, clean flavor. A strong sour, rancid, ammonia-like, or very fishy odor can indicate spoilage.
Can I use a whole side of coho?
Yes. Place it skin-side down, glaze evenly, and begin checking after 12 minutes. A large side may need 15 to 20 minutes depending on thickness.
Can I make this recipe without soy sauce?
Yes. Use 1 tablespoon melted butter or olive oil plus an extra pinch of salt, or choose coconut aminos for a soy-free alternative.
Can I prepare the glaze ahead?
Yes. Refrigerate it in a sealed jar for up to 3 days. Warm briefly so the honey loosens before brushing it on the fish.
Why is white liquid coming from the salmon?
That is albumin, a harmless protein. It becomes more visible when salmon cooks quickly or too long. Gentle handling and avoiding overcooking reduce it.
Is wild coho salmon sustainable?
NOAA states that U.S. wild-caught coho is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations. Check the source label because fisheries and stocks vary.
Nutrition Note
NOAA lists raw coho salmon at about 146 calories, 21.62 grams protein, and 5.93 grams fat per 100 grams. The recipe estimate also includes the glaze and oil.
