Warm, cheesy, and full of savory flavor, this Cheddar Cornbread Breakfast Casserole with Bacon is the kind of dish that makes the whole kitchen smell like Saturday morning. It’s hearty without being heavy, and it brings together pantry staples in a way that feels special. You get crisp bacon, tender cornbread, and a creamy egg custard all in one sliceable pan.

What Makes This Special

This casserole combines the nostalgia of cornbread with the comfort of a classic breakfast bake. The cornbread base soaks up a savory egg mixture, so every bite stays moist and flavorful.

You get a balance of textures: crisp bacon on top, melty cheddar throughout, and a soft, custardy center. It’s also simple to assemble and bakes in one dish, making cleanup straightforward. Best of all, it holds well, so you can make it ahead and reheat without losing quality.

Ingredients

• 8 slices thick-cut bacon, chopped
• 1 tablespoon butter (for greasing the dish)
• 1 box (8.5 oz) cornbread mix or your favorite homemade cornbread batter
• 2/3 cup milk (for the cornbread mix, or as your mix directs)
• 1 large egg (for the cornbread batter)
• 1 tablespoon honey (optional, for a touch of sweetness)
• 8 large eggs (for the custard)
• 1 cup whole milk or half-and-half
• 1/2 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1/2 teaspoon smoked paprika (optional, but great with bacon)
• 1 cup shredded sharp cheddar cheese, divided
• 1/2 small yellow onion, finely diced
• 1 small red bell pepper, diced
• 2 green onions, thinly sliced
• 1 tablespoon chopped fresh parsley (optional, for garnish)

How to Make It

1. Preheat and prep the pan. Heat your oven to 400°F (200°C).

   Grease a 9×13-inch baking dish with butter. This keeps the cornbread from sticking and adds flavor.

2. Cook the bacon. In a skillet over medium heat, cook the chopped bacon until crisp, about 8–10 minutes. Transfer to a paper towel–lined plate.

   Reserve 1 tablespoon of the bacon drippings in the pan and discard the rest.

3. Sauté the vegetables. Add the diced onion and red bell pepper to the reserved drippings. Cook until softened and lightly golden, 4–5 minutes. Set aside to cool slightly.
4. Mix the cornbread batter. In a bowl, stir together the cornbread mix, milk, 1 egg, and honey (if using) until just combined.

   Do not overmix; a few lumps are fine.

5. Par-bake the cornbread base. Spread the batter evenly in the greased baking dish. Bake for 10–12 minutes, just until the top is set and lightly golden. This step helps the base hold up to the custard.
6. Whisk the egg custard. In a large bowl, whisk the 8 eggs with the milk or half-and-half, salt, pepper, and smoked paprika.

   Stir in half the shredded cheddar and the sautéed vegetables.

7. Assemble the casserole. Reduce oven temperature to 350°F (175°C). Sprinkle half the cooked bacon over the warm cornbread base. Pour the egg mixture evenly over the top.

   Sprinkle with remaining cheddar and bacon, and add the green onions.

8. Bake until set. Bake for 28–35 minutes, or until the center is just set and a knife inserted near the middle comes out clean. Avoid overbaking to keep it tender.
9. Rest and serve. Let the casserole rest for 10 minutes. Garnish with parsley, slice into squares, and serve warm.

Keeping It Fresh

Leftovers keep well and make easy breakfasts.

Let the casserole cool completely, then cover tightly and refrigerate for up to 4 days. Reheat slices in a 325°F oven for 10–12 minutes or in the microwave in short bursts to avoid drying out. For longer storage, freeze portions in airtight containers for up to 2 months.

Thaw overnight in the fridge, then reheat in the oven for best texture. If the top looks dry, a light splash of milk on the slice before reheating helps bring back moisture.

Health Benefits

This casserole delivers a satisfying balance of protein, carbs, and fat. Eggs provide high-quality protein along with B vitamins and choline for brain and nerve health.

Cheddar adds calcium and flavor, so you don’t have to use a huge amount to feel satisfied. Bell peppers bring vitamin C and antioxidants, and onions add prebiotic fibers that support gut health. You can also tweak it to fit your goals.

Swap whole milk for 2% to reduce saturated fat, or use turkey bacon for a lighter option. Adding extra vegetables—like spinach, zucchini, or mushrooms—boosts fiber and micronutrients without changing the cozy vibe of the dish.

Pitfalls to Watch Out For

• Skipping the par-bake: Pouring custard onto raw batter can make the base gummy. Par-baking keeps the cornbread tender, not soggy.
• Overbaking: The eggs will continue to set as the casserole rests.

  Pull it when the center is just set to avoid a dry texture.

• Too much grease: Drain bacon well and don’t add excess drippings to the custard. Too much fat can cause pooling and a greasy top.
• Underseasoning: Cornbread is mild. Taste your sautéed veggies and custard before baking and adjust salt and pepper if needed.
• Big veggie chunks: Large pieces can create pockets and make slicing messy.

  Keep the dice small and even.

Variations You Can Try

• Southwest Style: Add 1/2 cup canned green chiles, swap cheddar for pepper jack, and finish with cilantro and a dollop of salsa.
• Maple Bacon Twist: Brush the par-baked cornbread with 1 tablespoon maple syrup before adding the custard for a sweet-savory contrast.
• Veggie-Loaded: Fold in sautéed mushrooms, spinach, or diced zucchini. Reduce milk by 2–3 tablespoons if veggies are very moist.
• Sausage Swap: Use cooked breakfast sausage instead of bacon, or go half-and-half for deeper flavor.
• Cheese Mix-Up: Try a blend of sharp cheddar and Monterey Jack, or use smoked cheddar for a campfire note.
• Gluten-Free: Use a gluten-free cornbread mix and check labels on bacon and spices to ensure they’re gluten-free.

FAQ

Can I make this the night before?

Yes. Par-bake the cornbread, cool, then assemble with the custard, bacon, and cheese.

Cover and refrigerate overnight. Bake in the morning, adding 5–10 extra minutes if it’s going into the oven cold.

Do I have to use boxed cornbread mix?

No. A simple homemade batter works well.

Aim for a standard 8.5-ounce mix equivalent and keep the batter on the thicker side so it supports the custard.

What if I don’t eat pork?

Use turkey bacon, chicken sausage, or a plant-based bacon alternative. Be sure to add a bit of oil when sautéing the vegetables if you skip pork drippings.

How can I tell when it’s done?

The center should be set but still tender, with no liquid wobble. A knife or toothpick inserted near the center should come out mostly clean with a few moist crumbs.

Can I cut the recipe in half?

Absolutely.

Use an 8×8-inch pan, reduce bake times slightly, and start checking for doneness around 20–25 minutes.

What’s the best way to reheat without drying it out?

Reheat covered in a 325°F oven. For extra moisture, sprinkle a teaspoon of water or milk over each slice and cover with foil while warming.

Can I add potatoes?

Yes. Use pre-cooked hash browns or diced roasted potatoes.

Fold them into the custard and reduce other add-ins slightly to keep the balance right.
