Frequently Asked Questions
What is the best sausage for a breakfast casserole?+
Traditional bulk pork breakfast sausage (regular or sage-flavored) gives this sausage and egg casserole its most classic flavor. Try our homemade breakfast sausage patties crumbled up if you want to control the seasoning.
Can I use turkey sausage in this sausage egg bake?+
Yes — swap in ground turkey breakfast sausage for a lighter overnight sausage casserole. Add 1 tbsp olive oil to the pan since turkey sausage releases less fat.
How do I keep a sausage egg bake from being watery?+
Use day-old bread, drain the browned sausage well, and always let the assembled overnight breakfast casserole rest at least 4 hours so the bread fully absorbs the eggs.
Can I add vegetables to this breakfast casserole?+
Diced bell pepper, spinach, mushrooms, or green onions all work beautifully. Sauté extra-moist veggies first so they do not water down the sausage casserole.
