1 pound shrimp, peeled and deveined
2 teaspoons homemade or store-bought Creole seasoning
1/4 cup unsalted butter (1/2 stick)
1/3 cup all-purpose flour
1 medium yellow onion, finely chopped
2 celery ribs, thinly sliced
1 green bell pepper, seeded and finely chopped
4 garlic cloves, minced
1 (15-ounce) can tomato sauce (no salt added)
1 to 2 teaspoons hot sauce, to taste (optional)
1 teaspoon granulated sugar
1/2 teaspoon dried thyme
1/2 teaspoon dried oregano
1/2 teaspoon dried basil
2 dried bay leaves
Fine sea salt and black pepper
1/4 cup chopped scallions
1/4 cup chopped flat-leaf parsley leaves and tender stems
Steamed rice, for serving
Make the optional Creole seasoning: Combine all ingredients in a small bowl and stir together. The seasoning makes about 1/4 cup; store it in a closed container in a cool, dry place.
Toss the raw shrimp with 1 teaspoon Creole seasoning and set aside.
In a Dutch oven or large, heavy skillet, melt the butter over medium-low heat. Sprinkle the flour on top and stir constantly with a wooden spoon until a roux the color of peanut butter forms, about 10 minutes.
Add the onion, celery and bell pepper, increase the heat to medium and cook until softened, stirring occasionally, about 8 minutes. Stir in the garlic and cook until fragrant, 1 minute.
Stir in 1/3 cup water, then the tomato sauce, hot sauce (if using), sugar, thyme, oregano, basil, bay leaves, 1 1/2 teaspoons salt, 1/2 teaspoon black pepper and the remaining 1 teaspoon Creole seasoning. Bring to a simmer, then reduce the heat to low.
Cover and simmer for 10 minutes until thickened, stirring occasionally to make sure that the bottom doesn’t burn. (If needed, add more water.)
Once the stew has thickened, add the seasoned shrimp and simmer until opaque and cooked through, about 5 minutes, turning each piece halfway through the cooking time. Taste and adjust seasoning.
Remove from the heat and let stand for 10 minutes, uncovered. Sprinkle with scallions and parsley, and serve over steamed rice.
