In a large bowl, combine the chicken breasts and baby potatoes with olive oil. Season generously with salt and pepper, ensuring every piece is coated. Then, add garlic powder, thyme, basil, oregano, and 2 tablespoons of Ranch seasoning, mixing well to distribute evenly.

Pour the chicken broth into the Instant Pot. Carefully nestle the seasoned chicken in the broth, followed by the potatoes on top. Lock the lid in place and turn the vent to sealed.

Set your Instant Pot to 'pressure cook' for 10-15 minutes. Watch as the magic happens, transforming your ingredients into a fragrant meal!

Once the cooking time is up, do a 'quick release' by turning the vent to venting. Wait for the float valve to drop, then remove the lid and revel in the savory aroma.

Carefully drain the Instant Pot or use a slotted spoon to transfer the chicken and potatoes onto a large platter.

Sprinkle the dish with the remaining Ranch seasoning and grated parmesan cheese. For a fresh touch, garnish with chopped thyme or parsley before serving.
