There’s something about a cozy Southern morning that just begs for the smell of sizzling sausage and melted cheddar drifting from the oven. This Sausage Egg and Cheese Breakfast Casserole or “Christmas Casserole” as my family calls it has become a beloved holiday morning tradition.

- A handful of chopped spinach or bell peppers
- A pinch of crushed red pepper flakes
- Hot sauce or salsa for serving
Instructions
Step 1: Brown the Sausage
In a skillet over medium heat, brown the sausage, breaking it apart with a spoon. When nearly cooked through, add the minced onion and sauté until the sausage is browned and fragrant. Drain any excess grease.
Step 2: Whisk the Egg Mixture
In a large bowl, whisk together the eggs, milk, salt, and black pepper until well combined and slightly frothy.

Step 3: Layer the Casserole
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
Spread ¾ of the cooked sausage on the bottom. Sprinkle half the cheese evenly over the sausage, then pour the egg mixture on top.
Step 4: Bake
Place in the oven and bake for 30 minutes, or until the eggs are mostly set.
Remove the dish, top with the remaining cheese and sausage, then return to the oven for another 10–15 minutes, until the top is golden and bubbling.
Step 5: Rest and Serve
Let the casserole rest for 5 minutes before slicing. Serve warm with biscuits, toast, or fresh fruit. (And if you’re like most Southerners—don’t forget a dash of hot sauce.)

Tips & Tricks
- Make Ahead: Assemble the casserole the night before, cover with foil, and refrigerate overnight. Bake the next morning as directed.
- Low-Carb or Keto: Swap whole milk for heavy cream and use full-fat cheese.
- Add Veggies: Chopped broccoli, spinach, or bell peppers blend beautifully into the eggs.
- Reheating: Warm leftovers in a 350°F oven for 10–12 minutes or microwave individual servings for about a minute.
Substitutions & Variations
- Cheese Swaps: Try Monterey Jack, Colby, or a blend for a creamier flavor.
- Sausage Options: Turkey sausage or plant-based sausage work well too.
- No Dairy? Use unsweetened almond milk and dairy-free cheese shreds.
- Festive Flair: Sprinkle diced red and green peppers on top for a Christmas-morning look.
