Instructions:

  1. Preheat your oven to 350°F (175°C), ensuring it’s fully heated before placing your dish inside.

  2. Prepare the sour cream mixture: In a medium-sized saucepan, melt the butter over low heat. Once melted, stir in the lemon juice and sour cream, blending them together until smooth and well-combined. This mixture will form the creamy base for your casserole.

  3. Season the fish: Season your fish fillets (halibut or any white fish of your choice) with salt and pepper to taste. Make sure the fillets are evenly seasoned on both sides.

  4. Assemble the casserole: Place the seasoned fish fillets into a casserole dish, arranging them in a single layer. Spread the onion rings evenly over the fish fillets, making sure to cover them generously.

  5. Add the creamy topping: Pour the sour cream mixture over the fish and onions, spreading it out evenly with a spatula to cover everything. This will give the dish a rich, creamy texture once baked.

  6. Top with cheese: Sprinkle the shredded cheddar cheese over the top of the casserole. Be sure to cover the surface well, allowing the cheese to melt beautifully as it bakes.

  7. Bake the casserole: Place the casserole in the preheated oven and bake for 35 minutes, or until the fish flakes easily with a fork. The cheese should be bubbly and golden brown on top.

  8. Serve and enjoy: Once the casserole is ready, remove it from the oven and allow it to cool for a few minutes before serving. This dish pairs wonderfully with a side of steamed vegetables or a fresh salad.

Tips:

  • For a lighter version, you can substitute the sour cream with Greek yogurt or a lower-fat cream cheese.
  • If you prefer a different type of cheese, feel free to swap the cheddar for mozzarella or even a combination of your favorites.
  • You can also experiment by adding herbs like dill or parsley for an extra flavor boost.

This Cheesy Baked Fillet of Fish Casserole is the perfect comfort food that’s quick to prepare, low in carbs, and packed with flavor. With its creamy texture and savory goodness, it’s sure to become a family favorite on your dinner table. Enjoy!
