Step 1

Cook the sausage links according to package instructions. Let them cool slightly, then slice them into bite-sized pieces.

Step 2

In a large bowl, whisk together the eggs, milk, salt, and pepper. Set the mixture aside.

Step 3

Grease a 9x13-inch baking dish. Layer the bottom with muffin cubes. Drizzle the melted butter on top.

Step 4

Top it with an even layer of sausages, cheeses, onion, and peppers. Pour the egg and milk mixture on top. Sprinkle it with bacon bits. Cover and refrigerate it for at least 2 hours or overnight.

Step 5

Take the casserole out of the fridge 30 minutes before baking.

Step 6

Preheat the oven to 350 degrees Fahrenheit. Uncover the dish and bake it for 45-50 minutes, or until a knife inserted into the center comes out clean. Let it cool.

Step 7

Slice, serve it, and enjoy!
