    Using An Instant Pot

    What does an Instant Pot do?

    An Instant Pot is 7 kitchen appliances in 1. It's a pressure cooker, slow cooker, rice cooker, steamer, sauté/searing, yogurt maker, and warmer. The pressure cooker setting cooks in a fraction of the time of traditional cooking methods.

    Is an Instant Pot worth it?

    An Instant Pot is a total game-changer. The first time I used my Instant Pot, I was absolutely sold on its functionality. The instructions were easy to follow and it produced a perfectly cooked meal that met my expectations. It's easy to use and makes weeknight meal prep a breeze. My favorite recipe so far is for Instant Pot Mexican Casserole. So delicious!

    What is the best thing to cook in an Instant Pot?

    Instant Pots are great for cooking: Meats, soups and stews, casseroles, mashed potatoes, steamed vegetables, and yogurt.

    Substitutions

    Bonus Proteins - This tasty recipe works with these bonus proteins: ground turkey, ground chicken, or ground bison. Mexican Casserole with ground beef is the traditional protein to use. But these other proteins work just as well. Use whatever sounds good to you.
