Activate the saute setting on the Instant Pot to heat the oil.
Add chicken, Creole seasoning, and a pinch of salt to the bottom of the pot. Cook until browned, then remove and set aside.
Cook onions and bell peppers in the pot until soft.
Return chicken to pot, then add rice, crushed tomatoes, and chicken broth. Stir together.
Cover the pot and select the rice setting for a high pressure cook of 12 minutes.
Perform a quick release of pressure. Place sausage over rice, then add a layer of shrimp on top of the sausage.
Switch the pot to manual mode and set it for a 2-minute cook.
After cooking, release the remaining pressure quickly or with a natural release. Stir the mix, evenly distributing sausage and shrimp throughout the rice.
Notes
Cooking the chicken: Make sure that the chicken is cooked all the way. The best way to do this is to use a meat thermometer. If the internal temperature is 165 degrees, the chicken is done cooking.
Searing the sausage: Before adding to the pot, sear the sausage slices on both sides to enhance their flavor and add a tasty char to your Jambalaya.
Deglazing the pot: After browning the meats, deglaze the pot with a bit of chicken broth to scrape up the tasty bits left behind, which will add an additional layer of flavor.
Layering ingredients: When adding the layers of ingredients, avoid stirring them together. This helps prevent the rice from sticking to the bottom and ensures even cooking.
Rinsing rice: Rinse the long grain rice under cold water before cooking to remove excess starch. This will help prevent clumping and keep your Jambalaya nice and fluffy.
Natural pressure release: After the final 2-minute cook time, allow the Instant Pot to naturally release pressure for at least 10 minutes. This will help the rice finish cooking perfectly.
Adding garnish: Sprinkle fresh chopped parsley or sliced green onions on top of the Jambalaya before serving for added color and a fresh flavor booster.
