Easy Shrimp Grits Casserole

The first time I had shrimp and grits was at this tiny roadside diner in Savannah, Georgia. It was 7AM and the place smelled like butter and coffee, and when that iron skillet hit my table, bubbling with cheese and pink curls of shrimp, I actually forgot to be grumpy about my early flight. Now whenever I make this casserole version, my whole apartment fills up with that same incredible aroma and I remember why Southern comfort food got its name.

Last winter I made this for a snow day dinner with friends, and honestly, nobody spoke for ten solid minutes after it came out of the oven. That is the highest compliment I know how to give. The way the Monterey Jack creates this golden brown crust while the shrimp stay tender underneath is just magic.

Ingredients

• 1 cup stone-ground grits: Trust me on this one, instant grits will turn this into something entirely different and not in a good way
• 4 cups low-sodium chicken broth: This becomes the flavor foundation of your grits so use something you would actually want to drink on its own
• 1/2 teaspoon kosher salt: Adjust based on your broth since some brands are saltier than others
• 2 tablespoons unsalted butter: One for the grits and one for sautéing the vegetables because butter makes everything better
• 1 cup shredded sharp cheddar cheese: The sharpness cuts through the rich grits and adds that punchy flavor that makes people lean in
• 1 pound medium shrimp: Peeled and deveined saves you about twenty minutes and nobody has time for that on a Tuesday night
• 1 tablespoon olive oil: Helps the spices coat the shrimp evenly so every bite has that smoky kick
• 1/2 teaspoon smoked paprika: This is what gives the dish that Southern depth without hours of simmering
• 1/2 teaspoon garlic powder: Distributed more evenly than fresh garlic would in the shrimp coating
• 1/4 teaspoon cayenne pepper: Leave it out if you are sensitive to heat but honestly, it makes the dish sing
• 1/2 teaspoon black pepper: Freshly ground if you have the energy
• 1/2 teaspoon kosher salt: For the shrimp seasoning
• 1 small onion: Finely chopped so it disappears into the dish instead of being chunky
• 1 green bell pepper: Adds this subtle sweetness that balances the spicy shrimp perfectly
• 2 cloves garlic: Minced fresh because this is the one place where fresh really does matter
• 2 tablespoons unsalted butter: For cooking down the vegetables until they are sweet and soft
• 1/2 cup shredded Monterey Jack cheese: Creates this incredible melted crust on top that everyone fights over
• 2 tablespoons chopped fresh parsley: Makes it look like you tried harder than you actually did

Instructions

Get your oven ready:

Preheat to 375 degrees Fahrenheit and grease a 9 by 13 inch casserole dish with butter or cooking spray. Do this first so you are not scrambling later.

Make the creamy grits:

Bring your chicken broth to a boil in a large saucepan then stir in the grits and salt. Turn the heat down to low, cover it, and let it simmer for about 15 to 20 minutes. You will know it is done when the texture is thick and creamy and not grainy anymore. Stir in the butter and cheddar cheese until everything is melted and smooth then take it off the heat.

Season the shrimp:

While your grits are bubbling away, toss the shrimp in a bowl with the olive oil, smoked paprika, garlic powder, cayenne, black pepper, and salt. Let them hang out on the counter for a bit so the flavors sink in.

Cook the vegetables:

Melt 2 tablespoons butter in a skillet over medium heat then add your onion and bell pepper. Sauté them for about 4 or 5 minutes until they are soft and fragrant then toss in the garlic for just one minute more.

Sear the shrimp:

Add those seasoned shrimp to the same skillet with your vegetables and cook them for just 2 or 3 minutes. You want them to turn pink and opaque but not overcooked or they will turn rubbery and sad.

Assemble everything:

Spread your cooked grits in the bottom of your prepared casserole dish then spoon the shrimp and vegetable mixture evenly over the top. Sprinkle the Monterey Jack cheese all over the surface so every bite gets some.

Bake until bubbly:

Slide the whole thing into the oven for 15 to 20 minutes. You are looking for the cheese to be melted and bubbling with some golden brown spots on top.

Finish and serve:

Let the casserole rest for about 5 minutes after you take it out of the oven then sprinkle with fresh parsley. Serve it warm while the cheese is still stretchy.

My roommate walked in while this was baking and literally said it smelled like a restaurant kitchen in our apartment. That might be the best compliment I have ever received.

Making It Ahead

You can absolutely assemble this entire casserole the day before and keep it covered in the refrigerator. Just add about 10 minutes to the baking time since it will be cold going into the oven. The flavors actually meld together even better this way.

Serving Ideas

A simple green salad with a vinaigrette cuts through the richness beautifully. If you want to go full Southern, serve it with collard greens or roasted okra on the side. For brunch, some crusty bread to soak up any extra sauce is not optional.

Storage And Reheating

Leftovers keep well in an airtight container in the refrigerator for up to three days. Reheat individual portions in the microwave at 50 percent power so the shrimp do not get tough, or cover the whole dish with foil and rewarm in a 325 degree oven.

• For the best texture, add a splash of broth before reheating
• The cheese crust will never be quite as crispy as the first day but it is still delicious
• This actually freezes surprisingly well if you wrap it tightly

There is something so satisfying about a dish that looks fancy but comes together in under an hour. I hope this becomes one of those recipes you turn to when you want to feed people something that feels like a hug.
