Can I make this casserole the night before?
Yes. Assemble the casserole in the baking dish, cover tightly with foil, and refrigerate up to 12 hours. Bake from cold, adding 5–10 minutes to the total baking time.
What type of sausage works best?
Bulk breakfast sausage (not links) is traditional and easiest to brown and mix. Use mild or hot depending on your preference.
Can I substitute the cheese?
Yes. Sharp cheddar, Monterey Jack, or a blend of cheddar and Swiss work well. Avoid low-moisture cheeses like parmesan.
How do I know when the casserole is done baking?
The eggs should be set but still slightly jiggly in the very center when you shake the pan gently. A knife inserted near the center should come out clean or with minimal wet egg.
Can I double this recipe?
Yes. Double all ingredients and use a 9x13-inch baking dish. Bake time may increase by 5–10 minutes.
