In a large saucepan of 3 cups of water, cook 2 cups uncooked long-grain white rice according to package directions. Remove from heat, keeping rice covered, and set aside.
Heat 1 tablespoon olive oil over medium heat in a large sauté pan or Dutch oven. Add in 12 ounces sliced andouille sausage and cook until the sausage starts to get some color.
Add 1 small diced onion, 1 diced green bell pepper, and 2 diced celery stalks. Allow this to cook for about 5-6 minutes, until the veggies are just starting to get tender.
Add in 3 cloves minced garlic, 1 ½ teaspoons Cajun seasoning, ½ teaspoon cayenne, and ½ teaspoon dried thyme. Stir to combine and allow this to cook for about 30 seconds to 1 minute until fragrant.
Pour in 3 cups chicken broth, 3 (15.5-ounce) cans red beans, and 1 bay leaf. Add salt and pepper to taste.
Bring to a boil, cover, and reduce the heat to low. Cook covered for 15 minutes. Remove the lid and continue to cook, stirring occasionally. Using a wooden spoon, gently mash the beans to help thicken.
Serve over rice and garnish with fresh chopped parsley.
