1. Prepare Beans (Night Before): In a large bowl, cover your dry kidney beans with about three times their volume of water. Let them soak in the refrigerator overnight – this helps them cook evenly and become super creamy.
2. Sear Sausage: Heat a large Dutch oven (or heavy pot) over medium heat without adding any oil. Place the sliced sausage in a single layer and cook until nicely browned on both sides. Use a slotted spoon to transfer the cooked sausage to a small bowl and refrigerate it for later.
3. Sauté Veggies & Spices: Melt the butter in the same pot, using the delicious drippings from the sausage. Add the chopped onions, bell peppers, and celery, cooking until the onions are soft (about 7 minutes). Scrape up any browned bits from the bottom of the pan to add extra flavor! Stir in the smoked paprika, onion powder, garlic powder, cumin, coriander, black pepper, cayenne, sage, and minced garlic, cooking for just one minute until fragrant.
4. Simmer to Perfection: Drain and rinse your soaked beans thoroughly, then add them to the pot with the sautéed vegetables. Pour in 8 cups of water, the Rotel tomatoes, chicken bouillon, dried parsley, oregano, thyme, basil, and bay leaves. Bring the mixture to a boil, then reduce the heat to medium-low, cover, and let it gently simmer for 90 minutes. Stir occasionally, especially during the last 30 minutes, to prevent sticking and encourage the beans to break down and become wonderfully creamy. If you like, you can mash a few beans against the side of the pot for extra creaminess. Add more water if the mixture gets too thick, or simmer uncovered for the last 30 minutes if it's too thin. Continue simmering if beans aren't tender enough.
5. Cook Rice: While the beans are finishing their last 30 minutes of simmering, prepare your long-grain white rice. A rice cooker makes this step effortless!
6. Finish & Serve: Once the red beans are tender and creamy, stir the browned sausage back into the pot and warm it through. Taste and adjust seasoning with extra salt or cayenne pepper if needed. Serve generous spoonfuls of the creamy red beans and sausage over your fluffy white rice. Garnish with fresh parsley and green onions, and add a dash of hot sauce if you like a little extra kick!
