Cut chicken breasts into small pieces. Season with salt and pepper, then toss in flour until coated.
Heat olive oil in a large pan over medium-high heat. Add the floured chicken pieces and fry 3-4 minutes, stirring occasionally, until golden brown on all sides.
Add white wine, chicken broth, and crème fraîche to the pan. Bring to a boil, then reduce heat to medium and simmer for 7-8 minutes until the chicken is cooked through.
Press 4 garlic cloves through a garlic press and stir into the sauce. Season with salt and pepper to taste. Serve immediately with noodles or rice.
