Add the red beans to the instant pot, and add water to an inch over the beans. Close the lid and press "Manual" and set the cooking time for 5 minutes. When done, let the pressure release naturally. Drain the beans and they're ready to go.
In a saucepan of 3 cups water (or, we prefer, chicken stock) cook rice according to package instructions; set aside.
Set a 6-qt Instant Pot to the high saute setting. Add olive oil and sausage. Cook, stirring frequently, until sausage is lightly browned, about 3-4 minutes. Transfer to a paper towel-lined plate; set aside.
Add garlic, onion, bell pepper and celery. Cook, stirring occasionally, until tender, about 2-3 minutes.
Stir in sausage, red beans, Cajun seasoning, oregano, basil, sage, thyme, bay leaves and vegetable broth; season with salt and pepper, to taste.
Select manual setting; adjust pressure to high, and set time for 30-35 minutes. When finished cooking, release pressure naturally according to manufacturerâ€™s directions, about 20-30 minutes.
Serve over rice with hot sauce and garnished with green onions.
Note:Â Store-bought Cajun seasoning worksÂ great (like Prudhommeâ€™s Blackened Redfish Magic or McCormickâ€™s Perfect Pinch Cajun) but here is a quickÂ recipe for Cajun Seasoning. Just mix everything together, use what you need and keep the rest ina n airtight container for another day.
