Baking coho salmon straight from frozen is one of those practical kitchen methods that feels almost too easy for how well it works. With just a few pantry ingredients, the fish roasts gently in the oven and turns out moist, flavorful, and weeknight-friendly, making this a useful recipe when you need dinner on the table without thawing or a lot of prep. Coho salmon has a rich but clean flavor that pairs especially well with simple seasonings, so this five-ingredient version keeps the focus on the fish while delivering a reliable, satisfying meal.
This salmon is especially good with roasted potatoes, steamed rice, buttered green beans, asparagus, or a crisp salad with a lemony dressing. If you want to round it out a bit more, warm dinner rolls or a scoop of herbed quinoa work nicely, and a wedge of lemon at the table helps brighten each serving.
5-Ingredient Oven Baked Coho Salmon
Servings: 4
Ingredients
2 frozen raw coho salmon halves, about 2 to 2 1/2 pounds total
4 tablespoons unsalted butter, melted
2 tablespoons lemon juice
2 cloves garlic, minced
1 teaspoon paprika
Directions
1. Preheat the oven to 425°F. Lightly grease an oven-safe roasting pan if needed, then place the frozen raw coho salmon halves in the pan, skin side down if the skin is still attached.
2. In a small bowl, stir together the melted butter, lemon juice, minced garlic, and paprika. Spoon or brush the mixture over the salmon as evenly as possible.
3. Roast uncovered for 20 minutes, then carefully remove the pan from the oven and spoon some of the melted seasoned butter from the pan over the salmon again.
4. Return the pan to the oven and continue roasting for 10 to 20 minutes more, depending on thickness, until the salmon flakes easily with a fork and reaches an internal temperature of 145°F at the thickest part.
5. Let the salmon rest for 3 to 5 minutes before serving so the juices can settle. Spoon any pan juices over the top when you plate it.
Variations & Tips
Add herbs: If you want a little more freshness, sprinkle chopped parsley, dill, or chives over the salmon after baking. This adds color and a brighter finish without changing the basic method.
Use smoked paprika: Swapping in smoked paprika gives the salmon a deeper, lightly woodsy flavor that works especially well with roasted potatoes or rice on the side.
Check doneness carefully: Frozen fish can vary in thickness, so start checking the thickest part near the end of cooking. The salmon should look opaque and separate into moist flakes without appearing dry.
Line the pan for easier cleanup: A sheet of parchment or foil in the roasting pan can make cleanup much simpler, especially since the butter and salmon juices can brown a bit during roasting.
Make it a little richer or brighter: For a richer finish, add an extra tablespoon of butter before the second roast. For a brighter finish, serve with extra lemon wedges so everyone can season to taste at the table.
