Wendy’s Egg Thing - Egg and Sausage Casserole
Some dishes become tradition not because they’re flashy, but because they show up every year—warm, reliable, and full of love. My mom, Wendy, has been making her “Egg Thing” every Christmas morning for as long as I can remember. It’s simple and comforting, the kind of breakfast casserole that brings the family together in pajamas and slippers while coffee brews and presents wait. The flavor is rich from the browned pork sausage and sharp cheddar, while cubes of white bread soak up the eggy custard to create soft, savory bites. After all these years, it wouldn’t be Christmas without it.

Main Dish
Wendy’s Savory Egg and Sausage Breakfast Casserole is the kind of hearty, no-fuss dish you’ll keep coming back to. Made with browned pork sausage, sharp cheddar cheese, and fluffy cubes of white bread suspended in a perfectly seasoned egg custard, it bakes into a rich, golden casserole that holds its shape beautifully when sliced. A touch of Colman’s mustard adds just enough depth, and a sprinkle of fresh cilantro brightens it up just before serving. It’s ideal for feeding a hungry crew, whether it’s a lazy Sunday or a family brunch.

Ingredients
- 1 pound ground pork sausage
- 2 1/4 cups whole milk
- 10 large eggs
- 1 1/2 teaspoons Colman’s dry mustard
- 1/2 teaspoon kosher salt
- 1 1/2 cups shredded sharp cheddar cheese
- 3 slices white sandwich bread, cut into 1-inch cubes
1/4 cup fresh cilantro, finely chopped (optional for garnish)
Directions
- Preheat the Oven: Set the oven to 350 degrees Fahrenheit.
- Cook the Sausage: In a large skillet over medium heat, cook the ground pork sausage until fully browned, about 6 to 8 minutes. Drain well and set aside.
- Make the Egg Mixture: In a large mixing bowl, whisk together the milk, eggs, Colman’s dry mustard, and kosher salt until well blended, about 1 minute on medium speed if using an electric mixer.
- Assemble the Casserole: Stir the shredded cheddar, bread cubes, and cooked sausage into the egg mixture until evenly combined. Pour into an ungreased 9x13-inch glass baking dish.
- Bake the Casserole: Bake for 30 to 40 minutes, or until the center is set and a knife inserted comes out clean.
- Rest and Serve: Remove from the oven and let rest for 10 minutes. Garnish with chopped cilantro, slice into squares, and serve warm.
