Simply The Best Baked Grits Casserole Recipe
Even though I’m a born and raised Midwesterner, classic southern recipes have always stolen my heart. Every since I was a little girl, I loved grits. Therefore, I couldn’t have been happier my beloved southern grits recipes continued to join loads of easy gluten-free side dishes ideas.
My oven grits casserole with cheese takes the ultimate comfort and boosts up up a notch. First, mix creamy grits with butter, milk, and handfuls of grated cheddar cheese. Pour into a greased casserole dish and bake until a golden cheesy crust tops thick and creamy grits.
Southern baked grits may be a common dish, but there’s something my recipe does that others don’t. Most cheese grits casseroles use milk to build up a creamy base. The problem with longer bake times, though, causes the milk solids to separate, leaving a watery layer underneath.
To fix this, I borrowed an ingredient hack from my silky, homemade gluten-free sweet potato pie – using evaporated milk. Canned milk already has most of the water content removed, so you are left with a concentrated cream milk base. When I added it to the casserole it was magic! Best results without fail.
Since this cheesy grits bake doesn’t have meat, it’s a great side option for to serve with eggs, breakfast meats or no canned soup hash brown casserole. When serving it for supper, it goes great with crispy, fried gluten-free shrimp, blackened fish, pork, braised beef, BBQ meats, or smoked sausages.

Prep the grits, eggs, and cheese
The recipe starts with preparing the grits on the stove top. To shorten the prep time, I typically make the casserole with quick grits, but feel free to use regular, old fashioned as well.
While they are cooking, grate the cheese (fresh off the block is best), and whisk together the eggs.

Whisk in eggs and bake
To temper the eggs before adding the rest of grits, I like to add a scoop of hot grits to the beaten eggs. Pour that mixture into the saucepan and stir everything to combine.
Pour the mixture into a greased casserole dish, sprinkle more cheese on top (why not?!), and bake to perfection!

I mostly use quick-cooking grits in the interest of time. If you have leftover cooked grits, I wouldn’t recommend using them for this recipe. Varying liquid amounts will cause unpredictability with baking. Instead spread them in a sheet pan and whip up some classic grit cakes!
Yummy Modifications
You can’t go wrong with cheesy baked grits, but I have zero issues with layering on even more goodness. Stir in cooked breakfast sausage, chopped ham, or cooked and crumbled bacon. To keep the dish vegetarian, you can also mix in veggies, such as sautéd mushrooms, onions, or peppers.
The grits can also be flavored with minced garlic, garlic powder, cayenne pepper, hot sauce or paprika. When in doubt – add more butter. 😉
