First, place the dry beans in your instant pot and cover them completely with water. Let them soak overnight or all day. (I would let them soak for at least 8 hours. This helps the beans soften up for cooking.)
Second, pour the soaked kidney beans into a strainer to get rid of the water you soaked them in and rinse.
Third, take your Instant Pot, turn it on the sauté setting, and pour in 1/4 cup of olive oil.
Add the chopped andouille sausage and cook until it begins to brown. Then remove the sausage and set aside. You will add them back in at the end once the red beans are finished cooking.
Next, add the finely diced onion, bell pepper, and celery to the Instant Pot and cook until the vegetables become translucent.
Add the soaked kidney beans to the instant pot and stir.
Then, add the garlic powder, onion powder, seasoned salt, thyme, and sage and mix well.
Add the chicken powder, water, and bay leaves, stir, and cover with the Instant Pot lid.
If you are using the slow cooker setting, cook for 8-10 hours. If you are using the pressure cooker setting, cook for 2 hours.
After the pot of red beans are finished cooking, take a potato masher and mash the beans until you get a creamy texture.
Once you have mashed your red beans, add the chopped smoked sausage and hot sauce to taste and mix.
Finally, serve your red beans and sausage over fluffy white rice and with a side of cornbread.
