  • 1 large salmon fillet: Approximately 1 1/2 to 2 pounds. Salmon is rich in omega-3 fatty acids, making it both delicious and nutritious. Substitution: You can use trout or tilapia if salmon isn’t available.

Step-by-Step Instructions

Now that we have our ingredients ready, let’s get cooking! Follow these simple steps to create your Cajun Butter Salmon & Shrimp Bake.

  1. Preheat your oven to 400°F (200°C). Lightly grease a baking dish or a foil tray.
  2. In a small bowl, whisk together the melted butter, olive oil, minced garlic, lemon juice, and spices.
  3. Place the salmon fillet in the center of the baking dish and spoon half of the butter mixture over the top, brushing it gently to coat.
  4. In a separate bowl, toss the shrimp and onion wedges with the remaining seasoned butter, then arrange them around the salmon.

  6. For a beautiful finish, switch on the broiler for the last 1 to 2 minutes, watching closely to prevent burning.
