FAQ
Can I use whole eggs instead of egg whites?
Yes. Use 12 whole eggs in place of 3 cups egg whites. The bake will be richer and may need an extra 3–5 minutes in the oven.
How do I keep it from getting watery?
Avoid very wet veggies or pre-sauté them to cook off moisture.
Let the bake rest 10 minutes before slicing so it sets cleanly.
What size pan works best?
A 9×13-inch dish gives five hearty portions with good thickness. An 8×11-inch pan works too but may need 5–8 more minutes.
Can I make it dairy-free?
Yes. Skip the cheese and swap cottage cheese or yogurt for an unsweetened, thick dairy-free yogurt.
Add nutritional yeast for a savory boost.
What should I serve with it?
Try hot sauce, salsa verde, sliced avocado, or a simple side of berries. For another make-ahead sweet brunch option, check out Overnight Cinnamon Roll French Toast Casserole.
