Melt the butter and mix with olive oil in a large bowl. Add minced garlic, parmesan, hot sauce, red pepper flakes, parsley, ranch seasoning, and dill. Mix well.
Add chicken pieces to the bowl and coat with the marinade. Let them soak.
Thread chicken pieces onto skewers and arrange them in the pressure cooker.
Seal the lid, set to high pressure, and cook for 10 minutes. Quick release.
Check if chicken is tender; if not, close the lid and let it naturally release for 5 additional minutes.
Remove skewers, let them rest, and serve hot.
Notes
Ensure wooden skewers are soaked in water for 30 minutes if using the grill.
