Boil some water on the stove and cook the broccoli florets in for around 5 minutes. Prepare a colander to drain the broccoli.
Cut the chicken to form bite-sized chunks.
Transfer the chicken pieces to a small casserole dish mix. Mix in with the cooked broccoli.
Use a separate bowl to make the sauce. Stir the sour cream, basil, and crushed garlic together. Flavor with the salt and pepper. Coat the broccoli and chicken with the sauce. Mix well.
Sprinkle the grated cheese evenly on the surface. Bake for around 7-10 minutes. Serve and enjoy!
