Rinse 1 cup stone-ground grits under cold water. Soak in fresh water for 10–15 minutes, then drain.
In a saucepan, bring 3 cups milk and 1 cup water to a gentle simmer.
Whisk in the drained grits and add 1 teaspoon kosher salt.
Reduce heat to low and simmer, stirring frequently, for 25–30 minutes until creamy and tender.
Stir in 3 tablespoons butter and adjust salt. Keep warm on very low heat.
Build the Shrimp and Sauce
In a cast iron skillet over medium heat, cook 4 slices diced bacon until crisp. Remove and set aside, leaving the fat in the pan.
Lower heat slightly and add diced onion and bell peppers. Cook slowly for 8–10 minutes until very soft and beginning to collapse.
Add 2 cloves minced garlic and cook 30 seconds until fragrant.
Increase heat to medium-high. Add shrimp in a single layer. Sear 1–2 minutes per side until just opaque and lightly caramelized. Remove shrimp briefly if pan becomes crowded.
Deglaze the skillet with ½ cup chicken stock (or grit cooking liquid). Simmer 2–3 minutes until slightly reduced.
Return shrimp and bacon to the pan. Add 1 tablespoon lemon juice and ½ teaspoon black pepper. Adjust salt.
To Serve
Spoon creamy grits into shallow bowls. Top with shrimp and pepper pan sauce. Serve immediately.
Notes
Notes• Soaking stone-ground grits improves texture and shortens cooking time.
• Do not overcook shrimp — remove as soon as opaque.
• The peppers should soften and melt, not remain crisp.StorageRefrigerate separately for up to 3 days.
Reheat grits gently with a splash of milk to loosen.
