Tips & Notes

Pro tips

Cook the sausage and bacon fully before adding to the casserole—undercooked meat won't finish cooking through in the bake time.
Whisk the eggs thoroughly and pour them evenly over the mixture to ensure they cook uniformly throughout the casserole.
Use a 9×13-inch baking dish and don't overfill; the casserole should be just under the rim to prevent overflow during baking.
Check doneness by inserting a knife near the center—it should come out clean with no liquid egg, around 45–55 minutes at 350°F.

Substitutions

breakfast sausage → ground turkey or plant-based sausage (adjust seasoning, as these may be less salty)
bacon → smoked ham or Canadian bacon (use same quantity, finely chopped)
sausage gravy → cream sauce made with butter, flour, and chicken broth with sage and black pepper
frozen hash browns → diced fresh potatoes parboiled 5–7 minutes (reduces moisture in the casserole)

Storage & make-ahead

Store covered in the refrigerator for up to 4 days. Reheat covered at 350°F for 15–20 minutes. The casserole also freezes well for up to 3 months when wrapped tightly.

Common Questions

Can I make this casserole the night before?

Yes, this is designed as a make-ahead dish. Assemble it completely, cover, refrigerate overnight, then bake the next morning. You may need to add 10–15 minutes to the baking time if baking from cold.

What temperature and time should I bake this at?

Bake at 350°F for 45–55 minutes, until the eggs are set and the top is lightly golden. The exact time depends on whether you bake it fresh or from refrigerated.

Can I use different cheese instead of cheddar?

Yes. Gruyère, Colby, Monterey Jack, or a blend work well. Avoid soft cheeses like fresh mozzarella, which won't melt evenly.

How do I reheat leftovers?

Cover with foil and warm in a 350°F oven for 15–20 minutes until heated through. You can also reheat individual portions in the microwave, though oven reheating preserves texture better.
