Cut your chicken into bite size cubes and place them in a bowl. Add your greek yogurt, paprika, chicken, chili powder, grand marsala, salt, and turmeric. Mix all the ingredients with the chicken and set it aside to allow the chicken to marinate.
Add your melted butter, coconut milk, tomato paste, tomato sauce, red curry paste, paprika, cayenne pepper, grand marsala, salt, onions and garlic. Stir all to combine in the pot.
After, add your chicken and stir.
Once everything is combined, place the pressure cooker to cook on high for 15 minutes. After the 15 minutes, rapidly release the pressure, by turning the pressure valve on top of the pressure cooker. (tip, place a heavy wet napkin on top of the pressure valve to avoid making a mess.)
Stir the chicken and press the sautee function and set it for 10 minutes. This will allow the sauce to boil and thicken.
Serve over jasmine rice with a side of naan and cilantro on top.
