Heat a skillet on medium heat and melt 1 tablespoon of butter in it.
1/4 cup butter
While it's preheating, season the chicken with the spices and salt.
4 chicken breasts, 1 1/2 teaspoons onion powder, 1 teaspoon garlic powder, 1 teaspoon salt, 1 teaspoon oregano, 1/2 teaspoon paprika, 1/2 teaspoon pepper
When the pan is hot, place the seasoned chicken breasts in it and cook for 5-7 minutes on each side until they're cooked through. Remove the chicken from the pan.
Turn the temperature down to medium-low and add the rest of the butter to the skillet. Use a spatula to loosen any bits of stuck on chicken.
Whisk in the bone broth and cream, and bring it to a slow simmer. Let it reduce for about 5 minutes, whisking frequently.
2 cups bone broth, 1/4 cup heavy cream
Slowly whisk in the tapioca starch slurry into the gravy. Continue whisking for a few minutes, until the gravy thickens.
2 tablespoons tapioca starch
Place the chicken breasts back into the gravy, and cook until they're heated through.
Season with additional salt and pepper to taste and serve immediately.
