📝 Ingredients

1 pound ground pork sausage
1 teaspoon mustard powder
½ teaspoon salt
4 large eggs, beaten
2 cups milk
6 slices white bread, toasted and cut into cubes
8 ounces mild Cheddar cheese, shredded

👨‍🍳 Instructions

Cook sausage in a medium skillet over medium heat, crumbling it as it cooks, until evenly browned. Drain well.
Whisk mustard powder, salt, eggs, and milk together in a medium bowl. Add sausage, bread cubes, and cheese; stir until evenly coated.
Pour mixture into a greased 9x13-inch baking dish. Cover and refrigerate for 8 hours or overnight.
Remove casserole from the refrigerator while the oven preheats to 350 degrees F (175 degrees C). Bake in the preheated oven, covered, for 45 to 60 minutes.
Uncover casserole and reduce the oven temperature to 325 degrees F (165 degrees C). Continue baking until the center is set and reaches 160 degrees F (71 degrees C), about 30 minutes. Let stand briefly before serving.
Enjoy!

💡 Notes & Tips

Cook’s Note

You can use croutons instead of making toast, and sage sausage for a different flavor. If you want to add any vegetables, cook them first and drain off any liquid so the casserole doesn’t become watery.

To fully bake the casserole ahead, let it cool completely, cover, and refrigerate for up to three days. Reheat it, covered, until hot throughout; uncover near the end if you want the top to crisp.
