01 - Heat vegetable oil in a large Dutch oven over medium heat. Add diced bacon and cook until crispy, about 5-6 minutes. Remove bacon with a slotted spoon and set aside, leaving the rendered fat in the pot.
02 - Add sliced andouille sausage to the pot and cook until well-browned on all sides, about 4-5 minutes. Remove sausage and set aside with the bacon.
03 - Add chopped onion, bell pepper, and celery to the pot. Sauté for 5-6 minutes until vegetables are softened and onions are translucent. Add minced garlic and cook for 1 minute until fragrant.
04 - Return the sausage and bacon to the pot. Add drained red kidney beans, chicken broth, bay leaf, thyme, smoked paprika, cayenne pepper, oregano, black pepper, and salt. Stir thoroughly to combine all ingredients.
05 - Bring the mixture to a boil, then reduce heat to low. Simmer uncovered for 45 minutes, stirring occasionally. If the soup becomes too thick, add a splash of water or broth to reach desired consistency.
06 - While soup simmers, rinse rice under cold water until water runs clear. In a medium saucepan, combine rice, water, and 1/2 teaspoon salt. Bring to a boil, reduce heat to low, cover tightly, and simmer for 15 minutes until rice is tender and liquid is absorbed. Remove from heat and let steam for 5 minutes before fluffing with a fork.
07 - Remove and discard the bay leaf from the soup. Stir in chopped fresh parsley. Taste and adjust seasoning with additional salt or cayenne if needed. Ladle hot soup into bowls and top with a generous scoop of fluffy rice. Garnish with extra parsley and serve immediately.
