Small Breakfast Casserole Recipe

Overnight breakfast casseroles are a breakfast lifesaver! By combining crusty bread, savory sausage, eggs, melty cheese, and a creamy milk mixture, then letting them soak overnight, you create a flavor-packed dish. The bread soaks up all that goodness, and you wake up to a ready-to-bake breakfast that’s incredibly satisfying.

Our single serving version is perfect for those cooking for one! It eliminates waste and lets you enjoy this classic comfort food without leftovers for days.

Ingredients

If you have any ingredients leftover from this single serve breakfast casserole recipe, check out our Leftover Ingredients Recipe Finder.

  • Pork sausage: Pork sausage adds a savory touch, but turkey or vegetarian sausage can be used for a lighter option. If you have leftover sausage, consider using it in a Pork Stir Fry or a Biscuit with Sausage Gravy.
  • Egg: You can use a large or extra-large egg in this recipe. The egg acts as a binder for the casserole.
  • Milk: I use whole milk or 2% milk in this recipe, you can choose non-dairy alternatives like almond or oat milk.
  • Salt and black pepper: Adjust the amount of salt and pepper to your liking.
  • Bread: Crusty varieties like French bread work best as they soak up the egg mixture without becoming too soggy. You can use day-old bread as well.
  • Cheese: You can use any type of cheese you like in this recipe. I like to use cheddar cheese for its flavor and meltability.

Recipe Variations

  • Spicy: Add red pepper flakes or diced jalapeños.
  • Vegetarian Breakfast Casserole: Replace the pork sausage with a veggie alternative.
  • Deluxe Casserole: Add some sautéed mushrooms and spinach.
  • Cheese-Filled: Use a mix of cheeses like mozzarella, cheddar, and pepper jack.

Expert Tips

  • Flavor Choice: This casserole tastes like a savory breakfast bread pudding. If you prefer sweet flavors, try my small French Toast Casserole recipe instead.
  • Soaking the Bread: Make sure the bread is well-soaked to get a good texture. But be careful not to soak it too much, or it will become too wet.
  • Resting Time Before Baking: Let the casserole sit at room temperature for about 10 minutes before baking. This helps it cook evenly.

Frequently Asked Questions

What is the ideal baking dish size for a mini breakfast casserole?

The success of this recipe depends on the size of the baking dish you use. I use a 5-inch baking dish that measures 5-inches x 5-inches and is 1 ¾-inches deep. This dish has a base area of 25 square inches.

A 4×6-inch dish with an area of 24 square inches and a 6×6-inch dish with an area of 36 square inches will work as well. For best results, use a dish of similar size.

If you would like additional information on the cooking and baking dishes I use in our “recipes for one”, please visit our FAQ page.
For examples of the dishes used at One Dish Kitchen, please visit our Store page.

Can I add vegetables to a breakfast casserole?

Yes, a few tablespoons of chopped bell peppers, mushrooms, or spinach work great.

How long can I store the unbaked casserole in the fridge?

It’s best when baked within 12-18 hours of preparation but an uncooked egg casserole can stay in the refrigerator for up to 2 days.

    I tried to post this before, and it said it was already posted. Clearly not the case.

    This was disgusting. Greasy, even though I laid it on paper towels, blotted it and rinsed it hot water in a sieve, soggy, and tasteless. Yuck!!!

    Apparently negative comments are not posted which would explain the five star ratings for every recipe even those will that were marginal at best.

    Use this site a lot and have loved many other recipes. However, this one is awful.

    1. Joanie says:

      I’m so sorry to hear this didn’t turn out as expected for you! I’ve made this dish many times and haven’t encountered it being greasy. The type of sausage can definitely make a difference. I recommend using a low-fat sausage next time. Also, rinsing the sausage with water might have made it soggy and bland.

      We have a helpful instructional video showing the detailed steps and final results, which might be useful.

      We value all feedback, no matter the rating, and always aim to help our readers achieve delicious results. Thank you for your honesty, and I hope your next cooking adventure is much more enjoyable!

  2. Mari says:

    I made the small breakfast casserole for one and it was excellent. I didn’t have French bread on hand so I use two handfuls of Texes toast croutons. It’s a definite keeper. Thanks

    1. Joanie Zisk says:

      I’m so happy you enjoyed it.

  3. Mary-Frances McIntosh says:

    Can it be cooked in microwave or air fryer I don’t have an oven?

    1. Joanie Zisk says:

      We have not tested this recipe in an air fryer.

  4. Kathy says:

    I am allergic to wheat so could you use hash browns instead?

    1. Joanie Zisk says:

      I haven’t tested this recipe using hash browns instead of bread.

  5. J. Hegyi says:

    Terrific recipe. For a different take on the recipe, you can substitute 2 cups of any (or assorted vegetables) for the bread cubes.
