Grits: A type of ground corn that is a staple in Southern cuisine, providing a creamy base for the casserole.
Water: Used to cook the grits and achieve the desired consistency.
Cheddar cheese: Adds a rich, cheesy flavor to the casserole.
Milk: Contributes to the creaminess of the dish.
Unsalted butter: Enhances the flavor and adds a silky texture.

Technique Tip for Perfect Grits Casserole

Alternative Ingredients
quick-cooking grits - Substitute with polenta: Polenta is also made from corn and has a similar texture and flavor, making it a suitable gluten-free alternative.
water - Substitute with chicken broth: Using chicken broth instead of water can add more depth and flavor to the casserole.
shredded cheddar cheese - Substitute with shredded gouda cheese: Gouda melts well and has a creamy texture that complements the dish, while still providing a rich flavor.
milk - Substitute with unsweetened almond milk: Unsweetened almond milk is a good dairy-free alternative that maintains the creamy consistency without altering the flavor significantly.
unsalted butter - Substitute with ghee: Ghee is clarified butter that is lactose-free and has a rich, nutty flavor, making it a great substitute.
salt - Substitute with sea salt: Sea salt can be used in the same quantity and provides a slightly different mineral content that can enhance the flavor.
black pepper - Substitute with white pepper: White pepper has a milder flavor and can be used to maintain the dish's seasoning without overpowering it.

How to Store or Freeze This Casserole
- Allow the Southern Grits Casserole to cool to room temperature before storing. This helps prevent condensation, which can make the casserole soggy.
- For short-term storage, transfer the casserole to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil. Store it in the refrigerator for up to 3-4 days.
- If you plan to freeze the casserole, portion it into individual servings. This makes it easier to reheat only what you need. Use freezer-safe containers or heavy-duty freezer bags.
- Label each container or bag with the date and contents. This helps you keep track of how long the casserole has been stored.
- To prevent freezer burn, ensure that the casserole is tightly sealed and that there's minimal air in the container or bag.
- When you're ready to enjoy the casserole, thaw it in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor.
- Reheat the thawed casserole in the oven at 350°F (175°C) for about 20-25 minutes, or until heated through. Cover with foil to prevent the top from over-browning.
- Alternatively, you can reheat individual portions in the microwave. Place the portion on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 2-3 minutes, stirring halfway through.
- For an extra touch, sprinkle a bit of shredded cheddar cheese on top before reheating to refresh the cheesy goodness.
- Enjoy your reheated Southern Grits Casserole with a side of fresh vegetables or a crisp salad for a complete meal.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover Southern Grits Casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Bake for about 20-25 minutes, or until heated through and the top is bubbly.
For a quicker method, use the microwave. Transfer a portion of the casserole to a microwave-safe dish. Cover it with a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape. Heat on medium power for 2-3 minutes, stirring halfway through to ensure even heating.
If you prefer a stovetop method, place the leftover casserole in a non-stick skillet over medium-low heat. Add a splash of milk or water to help rehydrate the grits. Stir frequently until heated through, about 5-7 minutes.
For a crispy twist, reheat the casserole in a cast-iron skillet. Preheat the skillet over medium heat and add a small amount of butter. Place the leftover grits casserole in the skillet and cook until the bottom is golden and crispy, about 5 minutes. Flip and cook for an additional 3-5 minutes.
If you have an air fryer, preheat it to 350°F (175°C). Cut the casserole into smaller portions and place them in the air fryer basket. Heat for 5-7 minutes, shaking the basket halfway through to ensure even heating.
