Step 1

Heat the olive oil in the inner pot at on Sauté. Add the sausage slices, and cook until browned, about 2 minutes per side. Transfer the meat to a paper towel–lined plate to drain.

Step 2

Add the onion, bell pepper, celery, and garlic and cook, stirring occasionally, until the onion is translucent, about 3 minutes.

Step 3

Add the Cajun seasoning, thyme, and rice, and stir until the rice is well coated in the oil. Press Cancel to stop the cooking.

Step 4

Add the tomatoes and their juices, the stock, and salt. Stir with a spatula freeing any food particles sticking to the bottom of the Instant Pot insert.

Step 5

Lock the lid. Cook on Manual High Pressure for 8 minutes, then allow a Natural Pressure Release for 5 minutes followed by manual release of the remaining pressure.

Step 6

Stir the rice mixture, then stir in the shrimp, scallions, and reserved sausage. Replace the Instant Pot lid and allow the ingredients to heat through for 5 minutes in the residual heat.
