Cooking Directions

  1. Preheat the oven to 400 degrees F (200 degrees C). Cut a small slit in each potato and place onto a baking sheet.

  2. Bake in the preheated oven until potatoes are easily pierced with a fork, about 1 hour and 10 minutes.

  3. When the potatoes are almost finished, melt 1/4 cup butter in a skillet over medium heat. Add onion; cook and stir until softened and translucent, about 5 minutes. Mix in Cheddar, cream, mustard, and lemon juice; season with salt and pepper. Cook, stirring frequently, until sauce is warm and Cheddar has melted, 3 to 5 minutes. Remove from the heat.

  4. Place white fish and shrimp into a 3 1/2-quart oven-proof baking dish. Pour cheese sauce over fish and stir until well combined.

  5. Scoop flesh out of baked potatoes and place into a large bowl; discard the skins. Add remaining 1/4 cup butter; season with salt and pepper. Mash with a fork until butter has melted and potatoes are smooth. Spread mashed potatoes evenly over fish.

  6. Return to the oven and bake until sauce is bubbling and potato topping is golden brown, about 55 minutes.

Tips

If you substitute frozen shrimp for fresh shrimp, thaw them before cooking.
