Grits are a mainstay in my home, and I’m loving the new line of rice grits from Ralston Family Farms for this recipe. My favorite grits for this recipe are the Nature’s Blend rice grits. They are hearty in flavor, not to mention I love the color! I also love the fact they are grown and manufactured in the US! You can get their products at Kroger, Whole Foods, Fresh Market, Fresh Thyme, Publix, and Costco.

How Do You Make Breakfast Casserole with Sausage and Grits?

This recipe is super simple to make. After browning the breakfast sausage, it’s as easy as boiling water, stirring in the grits, allowing them to thicken and stirring the cheeses, sausage, spices, and eggs, then pouring it into a casserole and baking it until it is hot and bubbly with melted cheesy goodness on the top!

Can You Make This Recipe for Easy Breakfast Casserole Ahead?

You can make this breakfast casserole several days ahead and put it in the refrigerator until ready to bake. Allow the casserole to warm a bit for about 10-15 minutes before baking. You may need to allow a little more time in the oven since the casserole is coming from the refrigerator.

Can You Freeze a Breakfast Casserole?

Yes, you can freeze breakfast casserole. It is best to freeze it unbaked, so that the texture of the meat (sausage) doesn’t change. Wrap the entire casserole in plastic wrap, then in several coats of foil. Don’t forget to label what it is and the date. You can freeze the casserole for up to 2 months.

How About Freezing the Leftovers?

Yes, you can freeze breakfast casserole leftovers! You can freeze the baked casserole in the baking pan as long as you allow the casserole to completely cool before wrapping it in plastic wrap and tin foil. If you have a small amount of leftovers, transfer the leftovers to an appropriately sized dish and wrap with plastic wrap then tin foil. Freeze for up to 4 months.

This dish is perfect for overnight guests, potlucks, and holiday mornings! I hope it becomes your new favorite.

If you serve this grits casserole for breakfast or brunch, all you’ll need are fruit and biscuits to go with it. On the other hand, if you serve this for dinner, just add a salad and rolls and a little sweet tea and you’ll be in business!
