FAQs
Can I make this casserole ahead of time?
Yes, you can prepare the biscuit base and egg mixture separately and assemble just before baking. Alternatively, assemble the entire casserole the night before, cover it tightly, refrigerate overnight, and bake in the morning.
Can I use regular milk instead of buttermilk?
Yes, you can substitute buttermilk with whole milk or 2% milk mixed with 1 tablespoon of lemon juice or vinegar per cup. Let it sit for 5 minutes before using to mimic buttermilk’s acidity.
