Easy Shrimp & Grits Casserole

The first time I made shrimp and grits, I was living in a tiny apartment with a kitchen that barely fit two people. My roommate from Georgia watched me stir the grits with intense concentration, nodding approval when I added way more cheese than any recipe called for. That night we ate straight from the casserole dish while watching a thunderstorm roll through, and I understood why Southern cooks treat this combination like family.

Last winter, my sister begged me to make this for her birthday dinner instead of going out to a fancy restaurant. She took one bite and declared it better than anything shed ever ordered in Charleston, then proceeded to ask for the recipe five times because she kept losing it in her phone.

Ingredients

• 1 cup stone-ground grits: These take longer to cook but have infinitely better texture and flavor than instant grits
• 4 cups low-sodium chicken broth: Using broth instead of water adds depth, but vegetable broth works perfectly for keeping it pescatarian
• 1/2 teaspoon kosher salt: Stone-ground grits need proper seasoning from the start since they take longer to cook
• 2 tablespoons unsalted butter: Added to the grits while theyre still hot so it melts completely into every spoonful
• 1 cup shredded sharp cheddar cheese: Sharp cheese cuts through the richness and adds that classic Southern flavor profile
• 1 pound medium shrimp: Peeled and deveined saves so much time, and medium shrimp are the perfect size for this casserole
• 1 tablespoon olive oil: Coats the shrimp evenly so the spices cling to every surface
• 1/2 teaspoon smoked paprika: This is the secret ingredient that makes people ask what you put in the shrimp
• 1/2 teaspoon garlic powder: Distributed evenly on the shrimp without burning like fresh garlic might
• 1/4 teaspoon cayenne pepper: Optional but I say go for it, that little warmth makes everything else sing
• 1/2 teaspoon black pepper: Freshly ground makes a huge difference here
• 1/2 teaspoon kosher salt: Brings out all the flavors in the shrimp seasoning
• 1 small onion: Finely chopped so it virtually disappears into the dish while adding sweetness
• 1 green bell pepper: The classic Cajun trinity component that adds fresh crunch
• 2 cloves garlic: Minced right before cooking so it stays fragrant and potent
• 2 tablespoons unsalted butter: For sauting the vegetables, because butter makes everything better
• 1/2 cup shredded Monterey Jack cheese: Creates that gorgeous melted top that everyone fights over
• 2 tablespoons chopped fresh parsley: Adds a bright pop of color and freshness against all that creamy richness

My dad, whos suspicious of any food that comes in a casserole dish, took a hesitant bite at our Sunday family dinner and immediately went back for seconds. Now he requests it every time he visits, calling it the exception to his casserole rule.

Making It Ahead

You can assemble the entire casserole up to a day ahead, cover it tightly, and keep it in the refrigerator. When youre ready to bake, add about 5 minutes to the cooking time since everything will be cold.

Serving Ideas

This casserole is substantial enough to stand alone, but a simple green salad with vinaigrette cuts through the richness beautifully. Some crusty bread on the side never hurt either.

Leftovers That Get Better

Reheat individual portions in the microwave with a splash of water or broth to loosen the grits. The flavors actually develop overnight, making leftover lunch the next day somehow even more delicious than dinner.

• Portion leftovers into containers before reheating to avoid drying out the edges
• A splash of cream or milk revitalizes the texture perfectly
• This freezes well for up to a month if you wrap it tightly

Theres something about this dish that brings people together around the table, lingering long after the last bite is gone.
