I don't know about any specific for the mini, but cutting in half the recipe sounds right. Also, I use lots of Insta pot recipes and I never really use their measurements. I just adjust to how I normally cook without a recipe and increase or decrease accordingly with my taste. I rarely find a recipe that is perfect.
Some of my my favorite recipes are Braised Beef, Pot Roast, Beef Stew, and Korean beef.
There are tons of 3-quart recipes on
