Easy Shrimp and Cheese Brunch Casserole to Make in Advance

Ingredients

• 4 tablespoons salted butter, softened, divided
• 6 slices white sandwich bread, crusts removed
• 1 cup grated Swiss cheese
• 2 green onions, chopped
• 2 tablespoons chopped fresh parsley
• ½ pound cooked small shrimp
• 1 ½ cups 2% milk
• ½ cup low-fat sour cream
• 3 large eggs
• ½ teaspoon Dijon mustard
• ½ teaspoon salt

Step 1

Butter an 8x8-inch casserole dish. Then, spread the remaining butter lightly on each slice of bread and cut them in half diagonally. Place half of the bread pieces in the bottom of the dish, and sprinkle over half of the Swiss cheese, green onions, parsley, and shrimp. Repeat these layers with the rest of the bread, cheese, onions, parsley, and shrimp.

Step 2

In a bowl, whisk together the milk, sour cream, eggs, Dijon mustard, and a pinch of salt until everything is well combined. Pour this mixture evenly over the casserole. Cover it up and pop it in the fridge for at least 8 hours, or overnight if you can.

Step 3

When you’re ready to bake, preheat the oven to 350°F (175°C). Bake the casserole for about 30 to 40 minutes, until it’s puffed up and golden on top. Let it rest for a few minutes before cutting into squares and serving.
