1-First Step: Prep the ingredients Finely chop the onion, green bell pepper, and celery. Mince the garlic and slice the Andouille sausage. Peel, devein, and remove the tails from the shrimp if needed, then pat them dry with paper towels. Dry shrimp sear and cook better, and they also blend into the sauce more cleanly.

2-Second Step: Start the shrimp base Heat 2 tablespoons butter and 1 tablespoon olive oil in a large heavy skillet over medium-high heat. Once the butter melts, add the onion and reduce the heat to medium-low. Cook for 3 to 4 minutes until the onion begins to soften. This slower start builds a sweeter, fuller flavor for the smothered sauce.

3-Third Step: Add the vegetables Stir in the green bell pepper and celery. Cook for 7 to 8 minutes until both vegetables are very soft. Do not rush this part. Those soft vegetables help make the sauce taste rich and cooked-down, which is what people love about classic Southern shrimp and grits.

4-Fourth Step: Build the seasoning layer Add the garlic, flour, Cajun seasoning, and cayenne pepper. Stir and cook for about 15 seconds. That short cook time wakes up the spices and removes the raw flour taste without burning the garlic. If your Cajun seasoning is strong, start with a little less and add more later.

5-Fifth Step: Add the sausage, broth, and tomatoes Stir in the sliced Andouille sausage, chicken broth, and diced fire-roasted tomatoes with their juices. Bring the mixture to a boil, then reduce the heat to low. Simmer for 8 to 10 minutes until the sauce reduces slightly and thickens. The sausage releases smoky flavor into the pan, and the tomatoes give the sauce a deep, savory body.

6-Sixth Step: Cook the grits While the shrimp mixture simmers, bring 3 cups chicken broth to a boil in a separate saucepan. Add salt to taste, then slowly stir in the quick grits. Cook according to the package directions, stirring often so the grits stay smooth. Once they are tender, stir in the Parmesan cheese, heavy cream, and freshly ground black pepper. The grits should look creamy, soft, and spoonable.

7-Seventh Step: Add the shrimp Stir the shrimp into the sauce and cook for 2 to 3 minutes, just until they are firm and pink. Be careful here, because shrimp cook fast and turn rubbery if they stay on the heat too long. If you need a milder dish, this is a good point to taste and adjust the cayenne or Cajun seasoning.

8-Eighth Step: Finish with cream and parsley Stir in the heavy cream and warm it through. Add the chopped parsley and taste for salt and black pepper. The cream smooths the sauce and brings all the savory pieces together. If the sauce feels too thick, add a splash of broth. If it feels too thin, let it simmer a little longer.

9-Final Step: Serve over creamy grits Spoon the Parmesan peppercorn grits into wide bowls and ladle the shrimp and sausage mixture over the top. Finish with extra parsley for a fresh pop of color. Serve right away while everything is hot and creamy. This dish pairs well with a simple green salad, roasted vegetables, or warm bread for scooping up the sauce.
