In a medium saucepan, bring the 4 cups of water or chicken broth to a vigorous boil. Gradually whisk in the 1 cup of stone-ground grits to prevent clumping. Reduce the heat to low and let the grits simmer, stirring occasionally, for about 20-25 minutes until the mixture is thick and creamy. For extra creaminess, stir in the 1/2 cup of heavy cream during the final 5 minutes of cooking. Season the grits with salt to taste.
While the grits are cooking, pat the 1 pound of shrimp dry using a paper towel. Season the shrimp with salt, black pepper, 1 teaspoon of smoked paprika, and 1/2 teaspoon of red pepper flakes, ensuring they are evenly coated.
In a large skillet, melt 2 tablespoons of unsalted butter over medium heat until it begins to bubble. Add the 4 cloves of minced garlic and sauté for about 1 minute until fragrant. Add the seasoned shrimp to the skillet, cooking them for 2-3 minutes on each side until they are pink and opaque. Squeeze in the juice from half of the lemon and sprinkle over the lemon zest, tossing to thoroughly coat the shrimp in the flavorful mixture.
Once cooked, remove the shrimp from the skillet and set them aside on a plate. In the same skillet, add the remaining 2 tablespoons of butter, stirring until it melts into a rich garlic butter sauce. Remove the skillet from heat.
Spoon the creamy grits into individual bowls, then generously top each serving with the garlic butter shrimp. Drizzle any leftover garlic butter sauce over the shrimp, and finish with a sprinkle of chopped green onions and parsley for a fresh touch.
Notes
Serve with lemon wedges on the side for a pop of color and an additional squeeze of freshness.
