Begin by preheating your oven to 350°F. This will ensure that your chicken cooks evenly while you prepare the rest of the dish.
Generously season both sides of the chicken thighs with salt, pepper, and Italian seasoning. This brings out their natural flavors wonderfully.
Heat vegetable oil in a large skillet over medium-high heat. Add the chicken thighs skin-side down and cook until nicely browned, which should take a few minutes, creating that perfect crispy skin.
Transfer the chicken thighs to a foil-lined baking sheet, skin side up. Bake them in the preheated oven until fully cooked through, making sure they reach that perfect doneness.
In the same skillet, heat a bit more vegetable oil over medium heat. Add the sliced mushrooms, and let them cook without salting them; this helps them caramelize for that rich flavor.
Mix in the chopped, cooked bacon with the mushrooms, then pour in the heavy cream along with a touch of salt and fresh thyme. Bring it to a boil, then reduce to a simmer for a little while to let those flavors meld.
Once the chicken is done baking, add the cooked thighs to the skillet. Spoon that creamy mushroom sauce on top, making sure each piece is covered in that indulgent mixture.
