I've mentioned before how much I'm enjoying my Instant Pot that Dustin gave me for Christmas. The more I use it, the more I am amazed with it! The other night I knew that I had some frozen pork ribs, but the only thing I really felt like doing with them was BBQ. And the only way I knew to do that was to slow cook them all day. But all these thoughts happened at 4:00 in the afternoon. I started looking for recipes using the Instant Pot and dealing with frozen meat. I had cooked some chicken from frozen in my Instant Pot and it hadn't worked as well as I had hoped, so I was looking specifically for tips to be successful with frozen meat. I came upon a website, www.hippressurecooking.com, and there were great tips for cooking frozen meat, as well as cook times. I decided to give it another try, and I'm so glad I did! After 20 minutes in the Instant Pot (plus pressurizing time), My ribs came out tender, moist and so delicious! I was totally amazed! Total prep, cook and de-pressurizing time was less than an hour--less time than my sweet potatoes took to bake in the oven. I am loving this new kitchen gadget. If you don't have an Instant Pot, but do have all day, I'm sure this would also be delicious in your slow cooker.
In saute mode, heat the oil in your Instant Pot. Saute the onions until they are translucent. Add the minced garlic and stir for 30 seconds. Brown the frozen pork ribs in the Pot (as best as you can, with them being frozen and probably stuck together). Add the salt, pepper and barbecue sauce and then pour enough water in to cover the ribs. Set the Instant Pot to the Meat setting, high pressure, and 20 minutes cook time. You can let it naturally depressurize, or do a quick depressurize, if you need to.
