Leftover Cornbread Breakfast Casserole
Not sure what to do with leftover cornbread? This Cornbread Breakfast Casserole recipe is a hearty egg bake with sausage, cornbread and black beans. It’s easy to make ahead for a brunch gathering.
As a family of three, we almost always have leftovers.
Leftover dinner, leftover baked goods, leftover ingredients. Since almost all recipes everywhere (including a lot of recipes on this blog, even) are written for four to eight servings, we always have an extra helping for that fourth person that isn’t at our table.
And honestly, we love it. We love being a family of three, happily eating our leftovers. It makes lunch the next day (at least for one of us) an autopilot meal, like microwaving the last slice of vegetarian quiche. Sometimes it means we can have mashed potato cakes with our weekend brunch.
With some meals, like a breakfast charcuterie board or cottage cheese breakfast bowls, it’s super easy to just adapt the quantities to what we need.
But with things like baked goods, it gets a little trickier. A batch of cornbread meant for two people won’t quite be enough for the three of us, but with a bigger recipe, we’re left with extra. Or sometimes we have extra after making chorizo stuffing.
Leftover cornbread, just on it’s own, is not my favorite. So today, I’m sharing the leftover cornbread breakfast casserole I’ve created to repurpose it into something new and delicious.
What to do with leftover cornbread?
Leftover cornbread can be used to make a casserole, a layered salad, or even a soup:
- The leftover cornbread breakfast casserole recipe below is my absolute favorite way to use up leftover cornbread, as I think the savory sausage and diced green chiles work so well with the sweet cornbread.
- A layered cornbread salad is another great savory leftover cornbread recipe. Please note that the recipe was developed to take to a party (10 servings), but you could make a half batch using 4 to 6 cornbread muffins (the exact amount of cornbread isn’t super important).
- This buttermilk cornbread soup sounds so intriguing, doesn’t it?
This leftover cornbread breakfast casserole is great for brunch for a crowd.
After I just got done telling you that my family of three always has leftovers, yes, this cornbread and egg casserole makes eight servings! I know, I know.
I’d make a half batch of this leftover cornbread recipe for us for a family brunch at home (and have one extra piece for lunch the next day).
But I think a dependable egg casserole like this one is best suited for putting on brunch for a crowd with minimal stress (see my How to Host the Best Brunch Buffet post for more tips for putting on a brunch gathering).
Whether it’s Easter brunch, a Mother’s Day family get together, or a holiday morning with houseguests, breakfast casseroles are essential for getting everybody fed with minimal stress for the chef.
This cornbread breakfast casserole is easy to prep ahead of time.
The reason this cornbread and egg casserole is so good for a crowd is that, just like my sweet potato breakfast casserole and pastitsio, you can assemble it ahead of time, leaving way less stress for the morning of.
Simply assemble the casserole up to the point of baking, then cover it tightly and keep it in the fridge up to 24 hours. When ready to serve, bring it to room temperature for 30 minutes, then bake!
This leftover cornbread recipe even works well as a reheatable weekday breakfast: you can assemble and bake it on the weekend, and then just reheat portions in the microwave as needed.

What’s in this leftover cornbread recipe, besides cornbread and eggs?
- the meat – I used turkey breakfast sausage (the kind sold in a roll) for this leftover cornbread recipe. Traditional sausage, veggie sausage, or oven baked bacon are also delicious options! Or, feel free to omit the meat to keep it vegetarian.
- black beans – I gave this cornbread breakfast casserole a Southwestern slant by adding black beans. I always have a can of black beans around for black bean meatballs, but pinto beans are great, too.
- diced green chiles – one small can of diced green chiles adds a little kick to this casserole, but isn’t too spicy.
- onions and garlic – what casserole isn’t better with onions and garlic?
- cheese – to keep assembly as easy as possible, I used shredded Mexican-style taco cheese for this sausage cornbread casserole. You can also shred your own sharp Cheddar, Colby Jack, or any other type of cheese you like.
- milk – I used whole milk because we always have it on hand (toddler life), but, just like with caramel coffee, whatever milk you keep around is fine.
- herbs – a sprinkle of fresh parsley or cilantro just before serving is welcome, but optional.
What to serve with this sausage cornbread casserole:
This leftover cornbread recipe is really a meal in itself, with cornbread, beans, eggs and breakfast meat all included in it!
But, if you’d like to serve this cornbread breakfast casserole alongside a little something sweet, I’d recommend my buttermilk blueberry muffins, mango banana bread or even a pear strudel.
Of course, there’s nothing wrong with simply serving this sausage cornbread casserole with a round of bloodies with everything bagel bloody mary salt and an epic garnish for a bloody mary!

I just made a double batch of corn muffins that stuck to the bottom of my muffin tin (despite using cooking spray), because I set the timer for 20 minutes instead of 15 (I keep forgetting about the “lower temps for nonstick pans” rule of thumb. 🙄).
So, I ended up with muffins that are now naturally crumbled up (ate two or three muffin tops with honey, though 🤤😋)…but now I need to use the crumbled bits in a recipe. Waste not, want not, right? 😅 I found your recipe for this fabulous sounding casserole, so am gonna give this a go. Just gotta snag some sausage at some point.
So glad you found this recipe, Kat! I hope your failed muffins (whoops!) were repurposed into a delicious casserole!
This looks so tasty! Looks like a great brunch dish. I found your website looking for a use for leftover cornbread, and Now I get to explore your other recipes. Great way to spend a snowy morning!
I’m so glad you found my site, Chris. Happy cooking!
Lori, this casserole sounds great. But IMHO, you haven’t had the right cornbread left over… 😇 I make mine with part mesquite flour, which changes the flavor in a wonderful way. We don’t mind at all having leftovers. I would be happy to share my cornbread recipe with you, as well as some mesquite flour (if you can’t find it anywhere). But sharing the flour would have to wait until cold weather because it does go rancid when not kept reasonably cold. My recipe serves 12, and I’ve been doing it as muffins, which we keep in the freezer for when we might need them.
This is fantastic! It has been requested again!
I am so glad to hear that, Kathryn!
I have left over corn bread muffins and sausage so this is perfect!! I also have some roasted poblano peppers that I’ll be adding. Can’t wait!
I hope this turns out great for you, Alicia. Love the addition of poblanos!
Could this be prepared the night before then baked the next morning?
Sure can, Lara! I’ve tried it, and it turns out just the same.
Can imagine what this dish is like – natural sweetness of the corn, savoury sausage, heat of chillies, and a whole lot more! Yum!!

Thanks so much, Julie & Alesah!
This recipe sounds great. I think I would probably make it for lunch rather than breakfast – I tend to like milder flavors for breakfast, and for some reason I can’t figure, I like eggs better for lunch. Definitely want to make this.
I had a piece yesterday for lunch, Susan. I love eggs for lunch, in general, as well!
This is exactly what I want to wake up to!
Everyone should have a few good breakfast casserole recipes in their repertoire. And this one fits the bill! It’s perfect for brunches and to bring to breakfast meetings and teacher appreciation brunches.
Great ideas, Anne-Marie! This would definitely travel well. Just bake, cover and take. In my opinion, it doesn’t even need to be served piping hot. As long as it’s warm, it’s good with me.
Do you think this could be frozen and then baked or would it not hold up?
Hi Heather! I’m honestly not sure. I would recommend looking up a few other egg casseroles and see if/how they recommend freezing them, then applying that here. Sorry I couldn’t be more help!
I think you sell it short by labeling it as “breakfast casserole” … I, quite frankly, liked that you served it as dinner the other night. I thought the flavors were great. Especially the mixture of the sausage with the cornbread. A real winning combination.
This looks fantastic – and I too am a huge fan of breakfast for dinner. The sausage and cornbread combo sounds scrumptiously hearty. Want!
Definitely very hearty! I left the sausage in kind of big chunks, and I really liked it that way 🙂
Yummy breakfast dish! Love the southwest spin with the black beans!
Thanks so much, Sandy!
Mmm, breakfast for dinner. Yum! I love this hearty casserole. Pinned.
Thanks Jennie! I’m all about breakfast for dinner!
