This breakfast bake is always a huge favorite. but sometimes this leftover cornbread breakfast casserole works and sometimes it doesn’t. Why? Because who has a bunch of leftover cornbread? If you had a big gathering and everyone brought cornbread, then most likely you’ll have enough to make this recipe. If not, like the most of us, we just have to make a separate batch of cornbread just for this morning bake. And that’s not a bad thing!

A Different Kind of Breakfast Casserole Bake with Cornbread

We’re always seeing the same type of hash brown breakfast bakes or anything that’s potato based. But years ago we decided to use some leftover cornbread and throw it all together in a baking dish. The results were fantastic and we never looked back. The savory and sweet combinations are perfect for mornings and brunch. Every time we’ve made this our guests have said it’s genius to use cornbread for a morning bake. They think we’re so smart but it’s really not rocket science.

How Much Leftover Cornbread is Needed for Breakfast Bake?

Ideally about 4-5 cups of cornbread works for this recipe. That’s equivalent to about an 8×8 pan of baked cornbread. If you have less cornbread, you can reduce some of the milk and eggs. It’s a great way to use leftovers so if you’re off a little on the cornbread amount, then it should still work with the rest of what’s listed in the recipe.

Ideally Use a Larger Baking Dish like a 9″x13″

Why? Because if you use a dish that’s too small, the casserole will be too thick and take longer to cook. Also, the egg mixture won’t bake all the way through The ideal pan is a 9″x13″ because there’s enough room to spread out the mixture and it’ll bake quicker and more evenly.

Can You Make this Day-Ahead?

Sure! this is a great make ahead breakfast bake for those family mornings that you need to feed a crowd. Just assemble everything right before baking and put it in the fridge overnight. But take it out at least 1 hour before baking. This ensures that the casserole isn’t too cold in the center and helps the casserole bake all the way through the center. You don’t want any raw egg. But if you didn’t let the casserole come to room temperature, then cover the bake with aluminum foil for the first 25 minutes of baking. The uncover for the last 5-15 minutes. Depending on how cold the casserole was, it could take longer to ensure that the egg is fully set.

Different Types of Breakfast Meat for Breakfast Bakes

In our recipe we used sausage but of course, you can use what ever you want. From cooked bacon to cooked ham or cooked chorizo, it’s all delicious. But just make sure that the meat is pre-cooked before you start to assemble the cornbread breakfast casserole. Don’t put any raw meat because baking because it won’t cook all the way through.

Vegetarian Versions for This Delicious Breakfast Bake

This yummy morning bake doesn’t need to have meat in it. Making it vegetarian that’s loaded with veggies is great too. Just sautee or cook the vegetables first before assembling. Here’s some cooked vegetable ideas to add:

  • different colors of sweet peppers
  • zucchini or squash
  • chopped kale or spinach
  • asparagus or mushrooms
  • additional corn

Leftover Cornbread Breakfast Casserole

If you have about 3 cups of leftover cornbread, then this recipe has a good ratio of meat and vegetables. But if you bake a new cornbread just for this casserole recipe (8×8 square pan) then you’ll have about 4-5 cups of cornbread. This is a lot for the ratio of other ingredients we listed below. With 4-5 cups of cornbread, you can double the amount of sausage, onion and bell pepper. But we suggest saving about 1 cup of the cornbread to eat alone, then use the remaining amount for this breakfast casserole. That way you don’t have TOO MUCH cornbread and can still keep the same amount of eggs and milk.
This bake is also great when it's re-heated and it will save you time in the morning. If you want to make this ahead of time, we recommend to cook the casserole a day or two before, let it cool and chill it. When ready to serve, bring it to room temperature about 1 hour before re-heating. Then re-heat in a pre-heated oven at 350°F for about 15 minutes
