Ingredients

• 1 teaspoon lemon juice
• salt and ground black pepper to taste
• 6 medium potatoes
• 2 teaspoons Dijon mustard
• 1 medium white Spanish onion, chopped
• 0.5 cup butter, divided
• 1.5 cups grated medium Cheddar cheese
• 1.25 cups light cream, or as needed
• 1.5 pounds white fish - skinned, boned, and cut into chunks
• 0.5 pound fresh shrimp, peeled and deveined

Recipe Instructions

Step 1

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

Step 2

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

Step 3

While the potatoes are baking, melt 4 tablespoons butter in a skillet over medium heat; stir in onion. Cook and stir until onion has softened and turned translucent, about 5 minutes. Mix in Cheddar cheese, 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 heat.

Step 4

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

Step 5

Scoop the flesh out of the baked potatoes and place in a large bowl; discard the skins. Add 4 tablespoons butter and season with salt and pepper. Mash with a fork until butter has melted and potatoes are smooth. Spread the mashed potatoes evenly over the top of the fish.

Step 6

Bake until sauce is bubbling and potato topping is golden brown, about 55 minutes.
