I am still super on the fence about the instant pot. I'll admit it makes super great hard boiled eggs, but it's an expensive way to do that. As for regular food I've definitely had mixed results. The one chicken dish I made came out fine (it was the recipe that needed tweaking for more flavor, not the instant pot). I cooked dried beans, total mixed bag, literally. Some of the beans were still hard, some were perfect, some were overcooked. I took my favorite black bean soup, read a similar recipe on Food Network so I could adjust mine to the instant pot and it came out great, even starting with dried beans.
I've seen people say that they throw frozen food in, adjust the cooking time a bit longer, and it comes out fine. Didn't work so fine here. Last night I was going to make sesame chicken and my chicken thighs were frozen. Looked at some recipes, estimated the cooking time, threw in the ingredients, and hoped for the best. Big fail! I'm just glad dinner was edible. After I released the pressure and took the lid off, the chicken was only partly cooked and the sauce was seriously starting to burn on the bottom of the pot. Big bummer. I took the thighs out and finished them cooking on the stove and rescued what sauce I could. At least with the finish of the pot it cleaned up easy. I think the main problem last night was that the thighs were frozen in a block, not individual, and I couldn't get them apart. Although really, I'm not sure it would have gone any better if they were individual frozen blocks; I think the sauce still would have burned anyway.
At this point I think I'll keep it and keep searching out recipes, trying them but I'm not wowed by the instant pot.
