To adjust recipe to use an Instant Pot, assuming Instant Pot duo (other models will be similar) 1. Press the “Slow Cook” key 2. Set cook time to 4 hrs by pressing the "+" or "-" key 3. Select desired cooking mode with the “Adjust” key, pressing to set to “Normal”, which is similar to temp of conventional slow cooker set to low. After 4 hours, check if the sausage is cooked through (recipe time is 4 to 6 hours). If not cooked through, repeat steps 1-3, choosing amount of time to finish in step 2
Agree recipe can be made on stove top or even on low temp in oven, but : Stove top requires monitoring, oven heats up the kitchen (a problem in the summer). Crock pot requires little supervision and the kitchen stays cool. But..... whatever works.
Sausage and peppers is one of our favorite meals. I usually make it on the stove top because that’s the way I do it. But I love the idea of making it in a crockpot. Essential to brown the sausage first. Then it takes care of itself and fills the house with that spicy, tangy aroma. Will serve over linguine the first night then make subs with some mozz on them for another night.
I subbed the crushed tomatoes and most of the spices for a jar of Rao's marinara because that's what I had on hand, and it still turned out fantastic. I also used chicken sausage and it was still great. My picky toddler had 3 servings!
I added some gnocchi for some starch. Very good.
My family did not enjoy this at all. It smelled good while cooking, but the texture of the sausages was mushy, the vegetables were tasteless; even the parmesan rind couldn't save it. Maybe I overcooked it? I followed the directions, except had the cooker on low for 7 hours and then warm for 1. 4 hour cooking times aren't doable for people with full time jobs.
