Why You’ll Love This Recipe
- Convenient: Prep it the night before, and in the morning, all you need to do is bake it.
- Flavorful: The overnight soak allows the bread to absorb the egg mixture, making every bite rich and delicious.

Overnight breakfast casseroles make mornings easier, and this one is a favorite of mine. I use crusty bread, sausage, an egg, cheese, and a creamy milk mixture. Everything soaks together overnight, so by morning, all I have to do is bake it for a warm, flavorful breakfast.
This small casserole is just the right size for one—no leftovers and nothing wasted.

Ingredients
If you have any ingredients leftover from this single serve breakfast casserole recipe, check out our Leftover Ingredients Recipe Finder.
- Pork Sausage: Adds a flavorful, savory element to the casserole. You can substitute with turkey sausage or vegetarian sausage for a lighter or meat-free option. Leftover sausage? Use it in recipes like Pork Stir Fry for one or a Biscuit with Sausage Gravy.
- Egg: A single large or extra-large egg works perfectly as the binder for this casserole, holding all the ingredients together.
- Milk: Whole milk or 2% milk is ideal, but non-dairy options like almond or oat milk can be used if you prefer.
- Salt and Black Pepper: Season to taste. Adjust based on your preferences or the type of sausage used, as some are already well-seasoned.
- Bread: Crusty bread varieties like small loaf French bread are best because they soak up the egg mixture without becoming too soggy. Day-old bread works great here, reducing waste and enhancing texture.
- Cheese: Choose your favorite cheese! Cheddar is my go-to for its rich flavor and excellent meltability, but other cheeses like mozzarella, Monterey Jack, or even a spicy pepper jack would work well.
Recipe Variations
Although this mini breakfast casserole is delicious as is, you might like to try these variations:
- Add Some Heat: Mix in red pepper flakes or diced jalapeños for a spicy kick.
- Vegetarian Option: Swap the pork sausage for your favorite vegetarian sausage or omit it entirely and load up on extra veggies.
- Loaded Casserole: Enhance the dish with sautéed mushrooms and fresh spinach for added flavor and nutrition.
- Cheese Lover’s Casserole: Use a blend of cheeses like mozzarella, cheddar, and pepper jack for a rich, melty breakfast casserole for one.
How To Make A Breakfast Casserole
These step-by-step photos and instructions help you visualize how to make an individual breakfast casserole. See the recipe box below for ingredient amounts and full recipe instructions.
- Cook the Sausage: Brown the sausage in a skillet over medium heat until fully cooked and no longer pink. Transfer to a plate lined with paper towels to drain excess grease, then set aside.
- Prepare the Egg Mixture: In a medium bowl, beat the egg. Whisk in the milk, salt, and pepper until well combined.
- Assemble the Casserole: Butter a 5×5-inch baking dish. Arrange the bread cubes evenly in the dish, then sprinkle the cooked sausage and shredded cheese over the top. Pour the egg mixture evenly over the bread, ensuring everything is coated.
- Refrigerate: Cover the dish tightly and refrigerate overnight to allow the flavors to meld.
- Bake the Casserole: The next day, remove the casserole from the refrigerator and let it sit at room temperature for about 30 minutes. Preheat your oven to 350°F (177°C). Bake the casserole, covered, for 25–30 minutes, or until the egg mixture is set and the top is lightly golden.
- Serve Warm: Remove from the oven and enjoy the casserole while it’s still warm.
Expert Tips
- Bread Soaking Tip: Make sure the bread is evenly soaked in the egg mixture for the best texture. Use just enough liquid to coat the bread without leaving excess pooling at the bottom, as too much soaking can make the casserole soggy.
- Room Temperature Before Baking: Allow the single serve breakfast casserole to sit at room temperature for 30 minutes before baking, especially if it was refrigerated overnight. This ensures even cooking throughout the dish.
- Customizable Ingredients: Don’t be afraid to experiment! Add extra spices like paprika or garlic powder for more flavor, or toss in diced vegetables like bell peppers or onions for added texture and nutrition.
- Cheese Tips: Use freshly shredded cheese for the best melt and flavor. Pre-shredded cheese can have additives that affect the texture.
- Baking Dish Size: A 5×5-inch baking dish works perfectly, but if you don’t have one, two 10-ounce ramekins can be used for a similar result.

We love this recipe! Just the right size for the two of us.
I made the casserole this morning, but I used leftover home fries instead of bread. I prepared it this morning and popped it right in the oven. It was delicious. Next time, I will try it with some kind of bred and compare.
So glad to hear you enjoyed it! Using leftover home fries is such a smart idea, it’s such a flexible recipe and perfect for making it your own!
Very disappointing. I should have known not to use so much sausage – nearly a half pound per person is way too much. The bread never got past soggy. The recipe needs to stress using two pans for doubling the recipe. I used one, and after an hour it was still not done. And, after all that, it had no taste. Will definitely not try again.
As mentioned in the FAQ section, if doubling the recipe, we recommend using a 6×8-inch baking dish to ensure even cooking. Doubling the recipe without adjusting the dish size as mentioned, or using two dishes is likely why the bread remained soggy and the casserole didn’t cook properly.
