Instant-Pot Apple Crisp Apple crisp in your Instant Pot?! Yes, you can! This easy Instant-Pot apple crisp has a nice balance of flavors from lemon zest and juice, brown sugar and sweet Honeycrisp apples. The whole-wheat flour and pecans add texture to the topping, which remains moist and delicious as it melds with the other flavors. To keep the texture from getting mushy, be sure not to cut the apple pieces too small. One-inch cubes will do the trick!
