Preheat your oven to 375°F.
Rub the chicken with salt and pepper generously.
Stuff with chopped onion, then place in the oven to roast for flavor enhancement.
In a large Dutch oven, heat a small amount of butter over medium-high heat.
Once the butter is melted and sizzling, add the seasoned chicken pieces.
Sear them until golden brown, roughly 8 to 10 minutes per side.
Once the chicken is seared, pour in the chicken broth and cream of chicken soup.
Stir well to combine, letting the mixture simmer gently while the flavors meld together.
Open the biscuit cans, tearing dough into small balls or slices.
Drop them into the simmering soup one by one, spacing them evenly.
Cover and allow them to cook, absorbing the broth's flavor for fluffy dumplings.
Check the seasoning, adding salt and pepper as needed.
Let simmer until the dumplings are fully cooked and tender to bite.
