I can’t take credit for this recipe, but I can honestly say that my friend Sallie’s Overnight Breakfast Casserole is the best breakfast casserole that I have ever tasted! Loaded with bacon, sausage, peppers, onions, and cheese, it’s got everything that you could possibly want in an egg dish — and you can make the entire meal in advance. It’s perfect for a holiday morning!

Easy Breakfast Casserole

My friend Sallie sent me this easy breakfast casserole recipe a few months ago, and it’s a dish that she originally found in one of those great local community church cookbooks. She has adapted the recipe over the years, mixed and matched different ingredients — and assures me that it comes out perfectly every time. Seriously, I think it would be hard to mess this one up!

Since the base is a combination of eggs and Bisquick mix, it has this wonderful texture that’s kind of a like a cross between a crustless quiche and thicker, chewier bread-based strata. Add plenty of cheese, veggies, sausage and bacon into the mix, and it’s bound to be amazing!

How to Make an Overnight Breakfast Casserole

This process is very simple and requires only 20 minutes of prep. Assemble the dish the night before and you can sleep in the next day, sip on your hot cup of coffee, and relax while your breakfast bakes in the oven. It’s the perfect solution for stress-free Christmas mornings or lazy weekends.

Ingredients

  1. Beat together Bisquick, eggs and milk.
  2. Stir in melted butter, grated cheese, browned sausage, cooked bacon, diced bell pepper, and diced onion.
  3. Transfer to a 9 x 13-inch baking dish.
  4. Cover and refrigerate for about 8 hours (or overnight).
  5. Bake at 350 degrees F for 45-60 minutes, or until golden brown and cooked through.

Tips for the Best Overnight Breakfast Casserole Recipe

  • To serve a smaller family, cut all of the ingredients in half and bake the casserole in an 8-inch square pan.
  • Any sausage will work well in this casserole. Try mild or spicy pork breakfast sausage, or use Italian sausage or turkey sausage.
  • I prefer usingwhole milk or creamfor this recipe. I don’t recommend low-fat or fat-free milk, since the fat in the milk or cream helps create the rich egg custard for the dish.
  • Use ham instead of the bacon or sausage.
  • Instead of cheddar, try other good melting cheeses like Monterey Jack, Pepper Jack, Colby or Gruyere.
