Cornbread Breakfast Casserole {Leftover Makeover}

Turn leftover Chili-&-Cornbread (or Anything & Cornbread) into a delicious layered Cornbread Breakfast Casserole.

To make this scrumptious layered Cornbread Breakfast Casserole, all you need is leftover cornbread, leftover chili or thick stew, and a handful of standard pantry and fridge staples. Easy-peasy!!!

Cornbread is one of those things that is best eaten the day it is prepared: after that, it quickly begins to toughen and lose its freshness.

Recently, while developing my recipe for Sweet Skillet Cornbread, I made four separate batches of cornbread in the same week. I usually try to string recipe tests out over a few weeks, but that didn’t happen this time, and as a result, we had a mountain of leftover cornbread.

Normally when I have leftover cornbread, I crumble and freeze it for use as breadcrumbs and casserole or pasta topping, but that lovely cornbread pile just called out to be made into something wonderful. 

My first thought was to make a savory cornbread pudding, but then, Ooo… What about a stratta? (FYI – stratta, or strata, is just a fancy name for a layered casserole, often prepared with bread). 

As it happened, we had a fridge full of fresh eggs thanks to Lady Bird Johnson and Harriet Lane Johnston (our two chickens), and a bowl of leftover chili. A plan began to take form. 

It is a long road from having a cool food idea to creating a viable recipe that is both tasty and can be successfully replicated by others. That road requires knowledge, preparation, organization, and testing, testing, testing. 

When I’m working on a new recipe, I usually make it between one and four times, depending upon how involved it is and how many times I’ve made it in the past. For tried and true recipes like Mom’s Spaghetti Sauce or Split Pea Soup, which I’ve made countless times in the past, I make a single batch to verify ingredient amounts, instructions, and cooking times – and so that I can take pictures, of course!

For original recipes like this Leftover Cornbread Breakfast Casserole, however, I make the recipe a minimum of three times, and often more. A few years ago, Mr B and I made at least seven batches of (Almost) Original Taco House Fiesta Dressing before we deemed it perfect.

Having all that extra leftover cornbread at the same time gave me the opportunity to make and test something new. As I chiseled away at my Mountain of Leftover Cornbread, turning it into a trio of breakfast casserole test runs, I started wondering about how other food writers, recipe developers, and bloggers approach the task of proving a new recipe, so I ask a few of my foodie friends to share a little about their process. 

It was interesting to learn how other food writers approach the challenge of testing out a recipe. I know first hand the amount of time and work involved, but the lengths some go to in pursuit of perfection surprised even me! (I’m looking at you and your 100 cakes, Eileen! 😉) Check out what they have to say: 

QUESTION: On average, how many times do you make a recipe from start to finish before posting it to your blog? What is your standard process for developing recipes?

Every recipe has been tested at least three times in my kitchen after it’s been perfected. First test is for measurement accuracy. Second is for timing. Third for photography. New recipes and new methods are tested more extensively before they enter this process. When someone tries a recipe from my blog I want them to know it will turn out and I can’t give that guarantee by making a recipe just once.

I make all of my recipes about 4 to 5 times before I post. The first two times are just for me and my husband to eat. I make most of my changes at this stage. The next two batches are given out to different groups of neighbors to get outside feedback. Finally, if I haven’t done it already, I make it one last time to re-shoot any photographs that I might want for the article.

Typically once 😂, sometimes twice, but the most to date I’ve repeated and photographed and tweaked was my Nutella Banana Bread; I made it 3x in 10 days. I share that experience in my post. Most of my recipes are tried and true and since my focus is easy and simple, if I can’t get it right the first time then I typically don’t make it again.

[I make a new recipe] at least 3 times, then more to test different substitutions that I know readers will ask about…so I usually make each one 10x (including one for photos and one for video). I work ahead so I spread out the batches (so we’re not eating the same thing 10x in a short time frame).
~ Laura, Joy Food Sunshine

Because I have a baking blog and baking recipes need to be precise, I usually make a recipe a minimum of 3x before I’m ready to post. Four or five tests for a recipe is not unusual. For my Pound Cake Perfection recipe I baked over 100 cakes to get the best recipe possible.
~ Eileen, Baking Sense

Usually it’s 3 times but sometimes more if I end up creating variations or if I want to test different methods of cooking (stove top, instant pot, etc). There was one time where I tested it like 6 times and ended up with so much leftovers that my husband told me to STOP! haha..because he ends up eating most of it.
~ JinJoo, Kimchimari

I make a recipe at least three times and sometimes more before the recipe is completely worked out. By the time I’ve done the video and the photos and all the recipe testing it’s a total of 7 or 8 times. By that time I never want to see it again. Lol. I actually have a little group of people who I call my baby bellies who take a lot of extras off of my hands..

Typically, the third time is the charm, although I have nailed recipe experiments on the first try (but made it again to be sure) … and abandoned ideas altogether after too many tries, chalking them up to “recipe fails.” When it comes to recipe development, like anything creative (plus scientific), you must be willing to fail in order to succeed.
~Kelly, Kitchen Gone Rogue

I like to make my recipes 3-4 times before posting, assuming it’s a brand new recipe. If it’s a family favorite that I’m just getting around to posting, it won’t take that many tries. If it’s a dessert recipe I try to time it around a social gathering of some sort so I can give a batch or two away.
~ Megan, Scratch to Basic

Overall, three successful trial runs seems to be the magic number for the majority of recipe developers who responded to my question, though clearly everyone puts their own spin on that triple-check. Many thanks to those recipe writers and bloggers quoted here, as well as the many others who chimed in, for all their hard work and dedication! 

Now it’s time to grab those leftovers out of the fridge and throw together one of the best breakfast casseroles you’ve had all year!

I found the act of arranging the pan-fried onions around the egg yolks quite therapeutic. I was thinking of Vincent Van Gogh while I was working.
