Place chicken cubes in large resealable bag. Mix together the minced garlic, pumpkin puree, 1/2 of the coconut milk, ginger, cinnamon, cloves, bay leaf, and salt. Pour 1/3 of the mixture in the bag with the chicken. Squish to coat the chicken and seal the bag, removing the air as you do.
Put the rest of the sauce mixture in a medium resealable bag. Close and staple that bag to the large bag above the seal. Freeze flat.
Instant Pot Cooking Instructions:
Thaw. Set your Instant Pot to sauté. Add in 2 Tbsp. olive oil and 2 Tbsp. butter. Add the chicken in batches, setting on a plate once browned. Add 1/2 cup water to pot, scrape the sides and bottom and turn off. Pour sauce from medium bag and add back the chicken. Lock the cover and seal the steam nozzle. Set to high pressure and cook for 7 minutes with a 10-minute natural release.
Stir in 1/2 cup of plain yogurt and 1/2 cup of coconut milk (or whipping cream). If you want, you can top it with cilantro.
Serve over jasmine or basmati rice or with Naan bread.
Crock Pot Cooking Instructions:
