Upside down cornbread is a play on upside down cake. Once baked, this cornbread will have a delicious onion topping that is so good!
This southern gal loves cornbread.
That’s no secret!
And while I have tons of cornbread recipes I love, this one might take the cake.
It’s a play on an upside down cake in that the batter bakes on top of caramelized onions to create that topping once you turn it out.
But, I use box cornbread mix to keep the recipe easy despite the showstopping results.
Ingredients
To make this you’ll need:
- Cornbread mix– You could use any kind you want but I always use Krusteaz’s honey flavored mix.
- Butter
- Onions– Small sweet onions, peeled and cut into thick slices
- Eggs
- Buttermilk– Don’t have buttermilk? Make your own by mixing a cup of milk with a teaspoon of white vinegar or lemon juice
- Cheese– Shredded cheddar cheese
- Onion powder
How to Make
To make this upside down cornbread, start by melting the butter in a 10″ round cast iron skillet set over medium low heat.
Once the butter is melted, carefully add the onions slices to the bottom of the pan so they are in a single layer.
Sprinkle salt and pepper on the onions and let them cook for 3 to 4 minutes until they just start to soften.
Then, carefully flip the onions, keeping them together as you do so.
Remove the skillet from heat and set aside.
Then, stir together the remaining ingredients in a medium sized mixing bowl just until everything’s evenly combined.
Carefully pour the batter into the skillet so it doesn’t disturb the onion slices.
Bake at 350° for 30-35 minutes, or until a toothpick inserted into the center of the cornbread comes out clean.
At this point, carefully remove the hot skillet from the oven and run a butterknife around the edges to release the cornbread from the pan.
Let the cornbread cool for 10-15 minutes in the skillet.
Carefully, and working quickly, turn the skillet over onto a clean cutting board.
Lift away the hot skillet and set aside.
Cut the upside down cornbread into 8 even slices.
Serve warm with butter and honey for drizzling, if desired.
Enjoy!
Storing Leftovers
Store leftover cornbread tightly wrapped in the fridge for up to 3 days.
Reheat before serving.
Tips and Tricks
- While you could use any brand of dry cornbread mix, I use Krusteaz. Specifically their honey flavored mix. I find it has the best flavor and contrasts nicely with the savory flavors of the onion and cheese.
- Stir ingredients together just until evenly combined. Be careful not to overmix. Overmixing prevents it from rising properly and achieving the proper fluffy texture.
- Even though the recipe incudes shredded cheddar and caramelized onions, it is still very much a SWEET cornbread recipe.
