Easy Shrimp & Grits Casserole

The first time I had shrimp and grits was at a tiny Charleston spot where the waiter warned me about the Cajun butter. I ordered it anyway and spent the entire meal trying not to lick the plate clean. That bowl of comfort stayed with me for years, until I finally decided to recreate it as a casserole my whole family could gather around.

Last winter, my sister came over feeling completely drained from work. I pulled this bubbling casserole out of the oven, and we stood at the counter with forks, stealing bites while it was still too hot. She said it tasted like a hug from someone who actually knows how to cook Southern food.

Ingredients

• Stone-ground grits: The coarse texture makes all the difference here—quick-cooking grits turn to mush, while stone-ground hold their shape and give you that perfect chewy bite.
• Low-sodium chicken broth: I learned the hard way that regular broth makes this casserole unbearably salty since we are seasoning everything else so generously.
• Sharp cheddar cheese: Use the good stuff—those crystals of aged flavor cut through the richness and add a tangy backbone that mild cheese just cannot deliver.
• Medium shrimp: Do not go larger than medium or they will shrink away to nothing in the oven. Peeled and deveined saves you precious prep time.
• Smoked paprika: This is the secret ingredient that makes people ask what you did differently. It adds this incredible depth without any actual smoke or heat.
• Monterey Jack cheese: I started using this on top because it melts into that gorgeous blanket of cheese that browns and bubbles in all the right places.
• Green bell pepper: Finely chopped so it almost disappears into the mix but adds that classic Southern flavor base.

Instructions

Get your oven ready:

Preheat to 375°F and grease a 9x13-inch dish with butter. Do not skip this step or you will spend twenty minutes soaking that pan later.

Cook the grits:

Bring your broth to a boil, stir in the grits and salt, then drop the heat to low. Cover and simmer for 15-20 minutes, stirring occasionally so nothing sticks to the bottom.

Make them creamy:

Stir in the butter and sharp cheddar until everything melts together into pure comfort. The grits should be thick enough to hold a spoon upright.

Season the shrimp:

Toss your shrimp with olive oil, smoked paprika, garlic powder, cayenne if you are feeling brave, pepper, and salt. Let them hang out while you cook the vegetables.

Sauté the veg:

Melt butter in a skillet and cook the onion and bell pepper until soft, about 4-5 minutes. Add the garlic for just one minute so it does not burn.

Cook the shrimp:

Add the seasoned shrimp to the pan and sauté until they turn pink and opaque, about 2-3 minutes. They will finish cooking in the oven, so do not overdo it now.

Assemble:

Spread the grits in your prepared dish, spoon the shrimp and vegetables on top, then sprinkle with Monterey Jack cheese.

Bake until bubbly:

Pop it in the oven for 15-20 minutes until the cheese is melted and bubbling and the whole kitchen smells incredible.

Finish with fresh herbs:

Let it rest for 5 minutes so everything sets, then sprinkle with chopped parsley. This is mostly for looks but it does add a nice fresh bite.

Save

My neighbor claimed she hated grits until she smelled this baking. She ended up taking half the leftovers home and texted me the next morning asking for the recipe. Sometimes food wins arguments better than words ever could.

Make-Ahead Magic

You can assemble the entire casserole up to a day ahead and keep it covered in the fridge. Let it sit at room temperature for about 20 minutes before baking, or add 5-10 minutes to the cook time. The grits actually absorb the flavors even better overnight.

Serving Suggestions

This casserole is surprisingly filling on its own, but a simple arugula salad with lemon vinaigrette cuts through the richness perfectly. If you want to go full Southern, serve with collard greens or roasted okra on the side.

Leftover Wisdom

The leftovers reheat beautifully and somehow taste even better the next day when the flavors have had time to really get to know each other. Store in an airtight container for up to three days.

• Reheat in the oven at 350°F for about 15 minutes to get that crispy cheese top back.
• Add a splash of broth or water before microwaving to keep the grits from drying out.
• This freezes well for up to two months if you wrap it tightly before freezing.

Save

There is something about pulling this bubbling dish out of the oven that makes people gather in the kitchen, forks in hand, ready for comfort. That is the kind of cooking I will never get tired of.
