Cajun Butter Salmon & Shrimp Bake

There is something so comforting about a dinner that feels a little special without asking too much from you, and this Cajun Butter Salmon & Shrimp Bake is exactly that kind of meal. It is rich, buttery, and full of bold, smoky flavor, with tender salmon, juicy shrimp, and sweet roasted onions all tucked into one pan. As it bakes, the kitchen fills with the scent of garlic, warm spices, and melted butter, which is usually enough to make everyone wander in and ask when dinner will be ready.

This is the sort of recipe that works beautifully when you want a cozy homemade meal that still feels impressive. It is perfect for a laid-back weekend dinner, a family gathering, or even one of those evenings when you want something hearty and satisfying without standing over the stove for an hour. Every bite is flaky, succulent, and kissed with a little Cajun heat, balanced by fresh lemon and parsley right at the end.

Ingredients

• 1 large salmon fillet (about 1 1/2 to 2 pounds)

• 1 pound large shrimp, peeled and deveined

• 1 large onion, cut into thick wedges

• 3 tablespoons olive oil

• 4 tablespoons unsalted butter, melted

• 4 cloves garlic, minced

• 1 tablespoon lemon juice

• 1 teaspoon paprika

• 1 teaspoon smoked paprika

• 1 teaspoon garlic powder

• 1 teaspoon onion powder

• 1 teaspoon Cajun seasoning

• 1/2 teaspoon black pepper

• 1/2 teaspoon salt, or to taste

• 1/4 teaspoon cayenne pepper, optional

• 1 tablespoon chopped fresh parsley

• Lemon wedges, for serving

Instructions

Start by preheating your oven to 400°F (200°C). Lightly grease a baking dish or a foil tray, just enough to keep everything from sticking.

Next, make the seasoned butter. In a small bowl, whisk together the melted butter, olive oil, minced garlic, lemon juice, paprika, smoked paprika, garlic powder, onion powder, Cajun seasoning, black pepper, salt, and cayenne if you want a little extra heat. It should smell bold and savory right away.

Place the salmon fillet in the center of the baking dish. Spoon about half of the butter mixture over the top, then brush it gently so the fish is nicely coated.

In a separate bowl, toss the shrimp and onion wedges with the rest of the seasoned butter. Once everything is glossy and well covered, arrange the shrimp and onions around the salmon.

Slide the dish into the oven and bake for 18 to 22 minutes. The salmon should flake easily with a fork, and the shrimp should turn pink and plump.

If you want a little more color, switch on the broiler for the last 1 to 2 minutes. Keep a close eye on it here. The edges can go from beautifully golden to too dark very quickly.

Once it comes out of the oven, sprinkle the parsley over the top and squeeze a little fresh lemon over everything. Serve it hot while the sauce is still bubbling gently in the pan.

Presentation

This dish looks especially beautiful served straight from the baking dish, with the salmon in the center and the shrimp and onions gathered all around it. Scatter the chopped parsley over the top for a fresh pop of color, and tuck a few lemon wedges around the edges for a bright finish.

For an extra cozy presentation, spoon some of the buttery pan sauce over the salmon just before serving. It is wonderful with fluffy rice, roasted potatoes, or thick slices of crusty bread that can soak up every last bit of that spicy garlic butter.
