Can I make this casserole vegetarian?

Absolutely. Skip the sausage or replace it with 1 cup sautéed mushrooms, caramelized onions, or white beans. You can also use 2 teaspoons extra vegetable broth, 1 tablespoon olive oil, or a handful of roasted garlic. The result stays savory, tender, and perfectly adapted to a meat-free fall breakfast casserole.

How do I know when the fall breakfast casserole is done?

Look for a deep golden top and a center that is mostly set with only a slight wobble. A knife should come out clean or with a few moist crumbs. Because ovens vary, check at the 42-minute mark and give it extra time if the edges are still pale.

What can I use if I do not have sweet potato?

You can use butternut squash, roasted acorn squash, or thin slices of russet potato. Any starchy vegetable with a light sweetness works well. Pre-cook it first so the texture stays tender and the custard sets evenly.

Can I make this fall breakfast casserole the night before?

Yes. Assemble everything, cover tightly, and refrigerate overnight. Bake in the morning, adding 5 to 8 minutes if the custard is cold. This is one of the most practical fall breakfast casserole choices for holidays and weekend getaways.

Ingredients

Scale

12 large eggs
1 1/2 cups half-and-half or whole milk
1/2 cup sour cream
2 tablespoons maple syrup
1 teaspoon vanilla extract
1 teaspoon dried sage
1/2 teaspoon smoked paprika
1 teaspoon salt
1/4 teaspoon black pepper
6 breakfast sausage links, cooked and crumbled
1/2 cup sharp cheddar cheese, crumbled
1 1/2 cups day-old bread cubes or biscuit pieces
2 medium sweet potatoes, thinly sliced and roasted
1/2 cup dried cranberries, optional
1/2 cup pumpkin seeds, optional

Instructions

Step 1: Preheat the oven to 350°F. Lightly grease a 9×13-inch baking dish with butter or cooking spray.

Step 2: Arrange the cooked sausage, roasted sweet potatoes, bread cubes, and cheddar evenly in the baking dish. Sprinkle with sage, smoked paprika, salt, and black pepper.

Step 3: In a large bowl, whisk together the eggs, half-and-half, sour cream, maple syrup, and vanilla extract until smooth.

Step 4: Pour the egg mixture evenly over the sausage, sweet potatoes, bread, and cheese. If using, sprinkle dried cranberries or pumpkin seeds over the top.

Step 5: Bake for 45 to 50 minutes, or until the center is set and the top is golden brown. If the edges brown too quickly, loosely cover the casserole with foil during the final 10 minutes.

Step 6: Remove from the oven and let the casserole rest for 10 minutes before slicing. Cut into 12 servings and serve warm.

Notes

Cook the sweet potatoes and sausage ahead of time to make morning preparation faster. For a lighter version, use turkey sausage and whole milk instead of half-and-half. Leftovers can be refrigerated for up to 4 days. Reheat individual portions gently until warmed through.
