This creamy shrimp and grits casserole bakes up golden, bubbly, and deeply satisfying with tender shrimp, rich cheddar grits, and smoky Southern flavor. Perfect for brunch, dinner, or your next potluck.

If there is one dish that captures the soul of Southern cooking in a single baking dish, it is this Creamy Shrimp and Grits Casserole. Imagine everything you love about classic shrimp and grits, the velvety cheddar-laced grits, the plump seasoned shrimp, the smoky sausage, all baked together into one golden, bubbling, deeply satisfying casserole. It is the kind of recipe that earns you recipe requests before people even finish their first serving.
Whether you are planning a leisurely weekend brunch, feeding a crowd at the holidays, or just want a show-stopping oven baked shrimp and grits dinner on a weeknight, this casserole delivers every single time. It is part Southern Living shrimp and grits tradition, part practical make-ahead magic, and entirely irresistible.
Traditional shrimp and grits is a stovetop dish that requires some last-minute attention. This casserole version solves that entirely. By cooking the grits low and slow first, then binding them with eggs and sour cream, you create a base that bakes up firm enough to slice but still impossibly creamy inside.
Here is what makes this baked shrimp and grits casserole recipe stand apart:
Chef's Tip: Shred your own cheddar from a block. Pre-shredded cheese contains anti-caking agents that prevent it from melting as smoothly, and you will taste the difference in the final texture.
A good heavy-bottomed saucepan is your best friend when making grits from scratch. It distributes heat evenly and prevents scorching at the bottom, which can happen fast if the heat is too high. The same goes for using quality stone-ground grits and a real Cajun seasoning blend with some heat to it.
This is the most important ingredient decision in the whole recipe. Stone-ground grits are dried corn kernels that have been coarsely ground, keeping more of the corn's natural oils and flavor. They take longer to cook (about 15 to 20 minutes on the stovetop), but the payoff is enormous: a rich, earthy, deeply corny flavor that forms the backbone of this casserole.
Instant grits cook in about 5 minutes but are heavily processed and often taste flat. If stone-ground is not available, regular old-fashioned grits (not quick-cook) are your next best option.
Heads Up: Do not skip the step of cooking the grits in chicken broth instead of just water. That single swap adds a savory foundation that makes the whole dish taste more complex.
This casserole is one of the most brunch-friendly recipes in the Southern repertoire. Here is why it works so brilliantly for a morning or midday spread:
For a shrimp and grits breakfast casserole spin, you can even layer in some scrambled egg mixture between the grits and the shrimp for an extra hearty morning dish.
Shrimp is notoriously easy to overcook, but in this casserole the risk is minimized because you only partially cook the shrimp in the skillet before they go into the oven. They finish cooking gently in the heat of the casserole, which keeps them tender and juicy rather than rubbery.

Preheat your oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish with butter or nonstick spray and set aside.
In a medium saucepan, bring the chicken broth and milk to a gentle boil over medium heat. Slowly whisk in the grits, reduce heat to low, and cook stirring frequently for 15 to 18 minutes until thick and creamy. Remove from heat and stir in 2 tablespoons of butter and 1.5 cups of the shredded cheddar. Season with salt and pepper.
While the grits cook, melt the remaining 2 tablespoons of butter in a large skillet over medium-high heat. Add the andouille sausage and cook for 3 to 4 minutes until lightly browned. Add the onion and bell pepper and cook for another 4 minutes until softened.
Add the garlic, Cajun seasoning, smoked paprika, and black pepper to the skillet. Cook for 1 minute until fragrant. Add the shrimp and cook just until they turn pink, about 2 to 3 minutes. They will finish cooking in the oven. Remove from heat and stir in hot sauce if using.
Whisk the beaten eggs and sour cream into the warm grits mixture until fully combined.
Pour the grits mixture evenly into the prepared baking dish. Spoon the shrimp and sausage mixture over the top and gently press it down so it is partially nestled into the grits.
Sprinkle the remaining 0.5 cup of shredded cheddar evenly over the top.
Bake uncovered for 25 to 30 minutes until the casserole is set, the edges are bubbling, and the cheese on top is golden.
Remove from oven and let rest for 5 to 10 minutes before serving. Garnish generously with sliced green onions.
This casserole is hearty enough to stand alone as a main course, but it also plays beautifully alongside roasted asparagus, a crisp Caesar salad, or crusty French bread for sopping up every last bit of those creamy cheddar grits.
For storage, refrigerate leftovers in an airtight container for up to 3 days. Reheat individual portions with a splash of broth to revive that creamy texture. Freezing is not recommended since grits tend to separate and become grainy once thawed.
