Place the butter and apple butter into a 9-inch by 12-inch baking pan (or similar size). Add the chicken breasts, red onion slices, apple slices and crushed garlic.
Combine the white wine, chicken stock and apple cider. Pour over the chicken in the pan.
Season with salt and pepper, Italian seasoning and rosemary sprigs. Toss to combine.
Take to the oven and bake for 20-25 minutes or until the internal temperature of the chicken reaches 165 degrees..
Turn the broiler on in the oven. Broil for 3 minutes watching it closely or until the chicken is golden brown.
Notes
● You can add some chili flakes if you want it to be slightly spicy.
● You can swap the onions for shallots too; the result is just as delicious.
