Step 1

Heat oil in a large, 6-quart Dutch oven or pot with high sides over medium heat. Add bell pepper, celery, and shallots, season with Cajun seasoning then saute with the lid on, stirring occasionally, until vegetables are nearly tender, 5 minutes. Turn heat up to medium-high then add sausage and continue sauting with the lid off until sausage is slightly browned and vegetables are tender, 5 minutes. Add garlic then saute until very fragrant, 30 seconds to 1 minute.

Step 2

Add rice, red beans, chicken broth, plus more Cajun seasoning then turn heat up to high to bring broth to a simmer. Place the lid back on top then turn heat down to medium-low (no higher!) and simmer for 10 minutes. Take the pot off the heat then let sit for 5 more minutes, covered, before removing the lid and fluffing with a fork. Taste then add more Cajun seasoning if desired and serve.
