This cheesy shrimp and grits casserole bakes smoky gouda, creamy grits, and spicy seasoned shrimp into one irresistible Southern-style dish perfect for brunch or dinner.

There is something about the combination of creamy grits, smoky gouda, and spicy shrimp that just feels like a hug in casserole form. This shrimp and grits casserole takes everything you love about the classic Southern dish and turns it into an easy, bake-ahead dinner that is just as good for a lazy Sunday brunch as it is for feeding a crowd on a weeknight. If you have ever made a stovetop version of shrimp and grits and wished it could feed more people with less last-minute fuss, this is the recipe you have been looking for.
What makes this version special is the smoked gouda cheese grits. Instead of plain cheddar, gouda brings a deep, slightly smoky richness that pairs beautifully with the cajun-spiced shrimp and crispy bits of bacon folded throughout. It is comforting, a little spicy, and endlessly satisfying.
Before we get cooking, the right tools and ingredients make a real difference here. A heavy bottomed saucepan helps the grits cook evenly without scorching, and good quality smoked gouda melts into the grits far better than a pre-shredded blend. These are the products that genuinely help this recipe shine:
The base of any great shrimp and grits casserole is the grits themselves, and the biggest mistake people make is rushing them. Stone-ground grits need a slow simmer to break down properly and release their natural creaminess. Instant grits will work in a pinch, but they will not give you that same luxurious texture once baked.
Chef's Tip: Stir the cheese into the grits while they are still warm but not boiling hot. This keeps the gouda from turning grainy and helps it melt into a silky, stretchy layer underneath the shrimp.
While the grits are simmering, this is the perfect time to build the topping. Crispy bacon, sweet bell pepper, and onion form the base, and a generous hit of cajun seasoning, smoked paprika, and cayenne pepper turns this into a spicy shrimp and grits casserole worth bragging about. A quick squeeze of fresh lemon juice at the end brightens everything up and keeps the dish from feeling too heavy.
The shrimp only need a couple of minutes per side. Since they will get a second, gentler cook in the oven on top of the grits, slightly undercooking them on the stovetop keeps them tender instead of rubbery once the casserole comes out of the oven.

This cheesy shrimp and grits casserole bakes smoky gouda, creamy grits, and spicy seasoned shrimp into one irresistible Southern-style dish perfect for brunch or dinner.
Preheat the oven to 375 degrees F (190 degrees C) and butter a 9x13 inch baking dish.
In a large saucepan, bring the water and chicken broth to a boil. Slowly whisk in the grits, then reduce heat to low and simmer, stirring often, for 20 to 25 minutes until thick and creamy.
Remove the grits from the heat and stir in 1 cup of the shredded gouda, 2 tablespoons of butter, salt, and black pepper until melted and smooth. Let cool for 5 minutes, then whisk in the beaten eggs until fully combined.
Pour the grits mixture into the prepared baking dish and spread evenly. Set aside while you prepare the shrimp.
In a large skillet over medium heat, cook the chopped bacon until crisp, about 5 minutes. Remove with a slotted spoon and set aside, leaving the rendered fat in the pan.
Add the remaining tablespoon of butter to the skillet along with the onion and red bell pepper. Cook for 3 to 4 minutes until softened.
Add the garlic, cajun seasoning, smoked paprika, and cayenne, and cook for 30 seconds until fragrant.
Toss the shrimp with a little extra cajun seasoning, then add to the skillet. Cook for 2 to 3 minutes per side until just pink and opaque. Stir in the lemon juice and remove from heat.
Spoon the shrimp, bacon, and pepper mixture evenly over the grits in the baking dish. Sprinkle the remaining 1 cup of gouda over the top.
Bake uncovered for 15 to 18 minutes, until the cheese is melted and bubbling and the edges are set.
Let the casserole rest for 5 minutes, then garnish with sliced green onions before serving.
This casserole is wonderfully flexible. Serve it straight out of the oven for a hearty dinner, or portion it into smaller dishes for an impressive weekend brunch spread alongside biscuits and a simple green salad.
For how to make this shrimp and grits casserole ahead of time, simply prepare the grits and shrimp topping, assemble everything in the baking dish, and refrigerate, covered, for up to a day before baking. This makes it a great option for entertaining, since most of the work happens well before guests arrive.
Heads up: If baking straight from the refrigerator, add roughly 10 extra minutes to the cook time and tent the dish loosely with foil for the first half of baking so the top does not brown too quickly before the center is hot.
Leftovers keep nicely in an airtight container in the fridge for up to three days. A splash of milk stirred in before reheating helps loosen the grits back to their original creamy texture, whether you warm it in the microwave or in a low oven.
However you serve it, this cheesy shrimp and grits casserole delivers all the cozy, smoky, spicy flavor of the Southern classic in a format that is practically built for sharing.
