This is a straightforward Cajun shrimp and grits — spiced shrimp and sautéed red bell pepper over cheesy, buttery stone-ground grits, ready in 45 minutes. It works on a weeknight and it works for company. The ingredient list is short enough that you probably already have most of it.
About the ingredients
- Stone-ground grits: Worth seeking out at most grocery stores, but regular (quick-cook) grits work fine here — just watch the liquid ratio on the package, as it differs. Instant grits are the one version worth skipping; the texture turns gluey once you add butter and cheese.
- Cajun seasoning: Store-bought blends vary a lot in salt content. Taste yours before you coat the shrimp — if it’s very salty, use a little less than the recipe calls for and season the finished dish at the end instead.
- Sharp cheddar: Any hard cheese you have on hand melts into the grits well. Gruyère, Monterey Jack, or even a mild cheddar all work. Pre-shredded bags contain anti-caking starch that slows melting, so grating from a block gives you a smoother result.
- Red bell pepper: Green bell pepper or a small poblano are easy swaps and cost less. Frozen diced peppers work too — just add them straight to the hot pan without thawing.
- Shrimp: Fresh or thawed frozen both work. If using frozen, pat them dry before seasoning so the Cajun coating sticks and the pan doesn’t steam.
The short version of why this works
Two things actually matter here. First, the grits need constant attention while they cook — stirring regularly prevents them from scorching on the bottom and keeps the texture smooth rather than lumpy. Pull them off the heat before they look fully done, then stir in the butter and cheese off the burner; residual heat finishes the job without making them stiff. Second, cook the shrimp in a hot pan and don’t crowd them. Shrimp release moisture quickly, and if the pan is too full or not hot enough, they’ll steam instead of sear — you lose the slightly caramelized edges that make the Cajun seasoning taste its best. Four minutes per side is the upper limit; pull them as soon as they’re opaque all the way through.
Common problems and fixes
- Grits turned stiff and thick before serving: Stir in a splash of warm water or milk, a tablespoon at a time, over low heat. Grits thicken fast as they sit, so do this right before you plate.
- Shrimp turned rubbery: They overcooked. Next time, pull them off the heat the moment the flesh is opaque — carry-over heat in the pan will finish the center. Four minutes per side is a maximum, not a target.
- Cajun seasoning tastes bitter or too sharp: This usually means the spices scorched. Keep the heat at medium-high, not high, and don’t let the pan sit empty and smoking before you add the oil and peppers.
- Grits taste bland even after seasoning: Cook them in salted water from the start — adding salt only at the end doesn’t penetrate the grain the same way. Also, the cheese and butter go in off the heat; if you add them while the pot is still boiling, some flavor cooks off.
- Everything’s ready but the grits seized up while you cooked the shrimp: Skip the garnish — not worth the extra dish — and get the shrimp straight into bowls. Thin the grits with a little warm water, plate immediately, and the whole thing comes together faster than fussing with scallion slices.

- Heat the olive oil in a large skillet over medium-high heat until the oil shimmers. Add the diced red bell pepper and sauté until softened, about 3 minutes. Push the peppers to one side of the pan. Add the seasoned shrimp in a single layer — work in batches if needed to avoid crowding.

Your questions, answered
Can I use quick-cook or instant grits instead of stone-ground?
Quick-cook grits are a fine substitute and cut the cook time significantly. Instant grits are less ideal — they tend to go gluey when you stir in butter and cheese — but they’ll still taste good if that’s what you have.
Can I make the grits ahead of time?
Yes, but they’ll thicken as they cool. Reheat them gently on the stovetop with a splash of water or milk, stirring until smooth, right before serving. Don’t reheat in a microwave without adding liquid first or you’ll get a solid block.
What if I don’t have Cajun seasoning in the pantry?
You can make a quick substitute with smoked paprika, garlic powder, onion powder, dried oregano, black pepper, and a pinch of cayenne — most of these are already in a standard spice rack. Combine roughly equal parts of each and add salt to taste.
Can this be made with a protein other than shrimp?
Andouille sausage sliced into coins is the most common swap and cooks in the same pan the same way. Chicken thighs cut into bite-sized pieces also work well — just increase the cook time to about 6 minutes per side and check that they’re cooked through before serving.
