Directions

Prepare the sausage: Cook and crumble the breakfast sausage in a skillet. Set it aside to cool slightly.
Mix the egg custard: In a large bowl, whisk together the eggs, milk, and seasonings.
Layer the casserole: In a greased baking dish, layer the bread cubes or hash browns, cooked sausage, and shredded cheese. Pour the egg mixture evenly over the top.
Bake: Bake at 350°F for 40–45 minutes, or until the eggs are set and the top is golden brown.
Cool and serve: Let the casserole cool for a few minutes before slicing and serving.

Expert Tips and Tricks

Use stale bread: Day-old bread works best as it absorbs the egg mixture without turning soggy.
Make it ahead: Assemble the casserole the night before, cover it, and store it in the fridge. Just pop it in the oven in the morning!
Test for doneness: Insert a knife into the center; if it comes out clean, the casserole is ready.

Recipe Variations and Possible Substitutions

Vegetarian option: Swap the sausage for sautéed mushrooms, spinach, or bell peppers.
Spice it up: Add diced jalapeños, crushed red pepper flakes, or hot sauce for some heat.
Cheese choices: Try mozzarella, pepper jack, or a blend of your favorites.
Gluten-free: Use gluten-free bread or skip the bread altogether and stick with hash browns.

Serving and Pairing Suggestions

This casserole is a meal in itself, but it pairs wonderfully with:

Fresh fruit salad or a side of mixed berries
A light green salad with a tangy vinaigrette
Warm biscuits or buttery croissants
Orange juice, coffee, or a mimosa for a brunch-ready spread

Storage and Reheating Tips

Refrigerator: Store leftovers in an airtight container for up to 3 days.
Freezer: Freeze individual portions for up to 2 months. Wrap tightly in plastic wrap and store in a freezer-safe bag.
Reheat: Warm in the oven or microwave until heated through. Cover with foil if reheating in the oven to prevent drying out.

FAQs

1. Can I use turkey sausage instead of pork sausage?
Absolutely! Turkey sausage is a leaner option and works just as well in this recipe.

2. What’s the best size for the baking dish?
An 8×8 or 9×13 dish works great, depending on how thick you want the casserole to be. Adjust the baking time slightly for a deeper dish.

3. Can I add vegetables to this casserole?
Definitely! Diced bell peppers, onions, spinach, or mushrooms are excellent additions for extra flavor and nutrition.

4. Can this casserole be made dairy-free?
Yes! Use a non-dairy milk alternative (like almond or oat milk) and dairy-free cheese to make this casserole suitable for those avoiding dairy.
