Ingredients

1 tablespoon unsalted butter
1 cup diced yellow onion (about 1 medium onion)
1 cup diced red bell pepper (about 1 medium pepper)
2 cups diced cooked ham (about 10-12 ounces)
12 large eggs
1 1/2 cups whole milk (or half-and-half for a richer casserole)
1 teaspoon Dijon mustard (optional, for added depth)
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon garlic powder
2 cups shredded sharp cheddar cheese
1 cup shredded Monterey Jack cheese
1/2 cup chopped fresh green onions, divided (for casserole and garnish)
6 slices of day-old bread, cut into 1-inch cubes (about 4 cups)

Instructions

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray.
In a large skillet, melt the butter over medium heat. Add the diced onion and red bell pepper and cook, stirring occasionally, until softened, about 5-7 minutes.
Add the diced ham to the skillet with the vegetables and cook for another 3-5 minutes, allowing the ham to slightly crisp and warm through. Remove the skillet from the heat and set aside.
In a large bowl, whisk together the eggs, milk (or half-and-half), Dijon mustard (if using), salt, black pepper, and garlic powder until well combined and slightly frothy.
Spread the bread cubes evenly over the bottom of the prepared baking dish.
Sprinkle half of the shredded cheddar cheese and half of the Monterey Jack cheese over the bread cubes.
Evenly distribute the cooked ham and vegetable mixture over the cheese layer in the baking dish.
Sprinkle the remaining cheddar and Monterey Jack cheeses over the ham and vegetable mixture.
Pour the egg mixture evenly over all the ingredients in the baking dish, ensuring the bread cubes are well saturated. Gently press down on any bread that floats to ensure it absorbs the egg mixture.
Sprinkle half of the chopped fresh green onions over the top of the casserole.
Bake for 45-55 minutes, or until the casserole is golden brown on top, puffed, and the center is set. A knife inserted into the center should come out clean.
Once baked, remove the casserole from the oven and let it rest for 10-15 minutes before slicing and serving. This resting period allows the casserole to set properly, making it easier to cut into neat squares.
Garnish with the remaining fresh green onions before serving.

Cooking Tips and Variations

To ensure your Kentucky Derby Casserole is a true champion, follow these tips. First, do not overbake. Overcooked eggs can become rubbery, so keep an eye on the casserole and remove it from the oven as soon as the center is set and the top is golden brown. Second, always allow the casserole to rest for at least 10-15 minutes after baking. This step is crucial for the casserole to firm up, making it much easier to slice into neat, presentable portions without falling apart.

For a richer, more decadent casserole, swap out the whole milk for half-and-half or even heavy cream in the egg mixture. This will yield a creamier texture and a more indulgent flavor profile. If you’re not a fan of ham, this casserole is incredibly versatile. You can easily substitute it with cooked and crumbled breakfast sausage, crispy bacon pieces, or even a combination of meats for a truly hearty dish. For a vegetarian option, simply omit the ham and increase the amount of vegetables, or add some cooked crumbled plant-based sausage.

Don’t be afraid to experiment with your cheese choices! While cheddar and Monterey Jack offer a classic, crowd-pleasing flavor, consider adding a touch of Gruyère for a nutty depth, or some smoked gouda for a unique smoky note. A sprinkle of Parmesan cheese on top during the last 10 minutes of baking can also add a delightful savory crust. You can also boost the vegetable content by adding sautéed mushrooms, spinach (ensure it’s well-drained to prevent a watery casserole), or finely diced zucchini. Just make sure to cook down any high-moisture vegetables before adding them to the casserole.

For an extra layer of flavor, consider adding a pinch of smoked paprika or a dash of hot sauce to the egg mixture. If you prefer a bit of a kick, a finely minced jalapeño (seeds removed for less heat) can be sautéed with the onions and peppers. Finally, for an added textural element, you can lightly toast the bread cubes in the oven before adding them to the casserole. This will help them maintain a bit more structure and prevent them from becoming too soggy, especially if you’re making the casserole ahead of time.

Storage and Reheating

Proper storage and reheating are key to enjoying your Kentucky Derby Casserole for days to come. Once the casserole has cooled completely to room temperature, you can store it in an airtight container in the refrigerator for up to 3-4 days. For individual servings, it’s often easiest to cut the casserole into portions before storing. This way, you can grab and reheat just what you need.

To reheat individual slices, the microwave is your quickest option. Place a slice on a microwave-safe plate and heat on medium power for 1-2 minutes, or until thoroughly warmed through. Be careful not to overheat, as this can make the eggs rubbery. For best results and to regain some of that crispy top, reheating in the oven is recommended. Place individual slices or the entire remaining casserole in an oven-safe dish, cover loosely with foil to prevent drying out, and bake at 300°F (150°C) for 15-20 minutes, or until heated through. If you prefer a crispier top, remove the foil for the last few minutes of reheating.

This casserole also freezes beautifully, making it an excellent option for meal prep. Once cooled, cut the casserole into individual portions. Wrap each portion tightly in plastic wrap, then aluminum foil, or place them in freezer-safe containers. The casserole can be stored in the freezer for up to 2-3 months. To reheat from frozen, you can either thaw overnight in the refrigerator and then reheat as described above, or reheat directly from frozen in the oven. For frozen portions, bake at 325°F (160°C) for 30-40 minutes, covered, until heated through, removing the foil for the last 5-10 minutes if desired.

Frequently Asked Questions

Can I prepare this casserole the night before?

Absolutely! This casserole is an excellent make-ahead dish. Prepare the casserole completely up to the point of baking, cover it tightly with plastic wrap, and refrigerate overnight. In the morning, remove it from the refrigerator about 30 minutes before baking to allow it to come closer to room temperature, then bake as directed. You may need to add an extra 5-10 minutes to the baking time.

What kind of bread is best for this casserole?

Day-old bread, such as French bread, sourdough, or even a sturdy white sandwich bread, works best. The slightly stale bread absorbs the egg mixture without becoming overly soggy. Avoid fresh, very soft bread as it can disintegrate too much during baking. Cutting the bread into 1-inch cubes ensures good distribution and texture.

How can I make this casserole spicier?

To add a kick, you can include a pinch of red pepper flakes in the egg mixture or sauté a finely minced jalapeño or serrano pepper with the onions and bell peppers. A dash of your favorite hot sauce drizzled over the top before serving also works wonders for those who enjoy a bit of heat.
