Preheat your oven to 350°F (175°C).

Grease a baking dish or line it with parchment paper.

Place the plain nonfat yogurt in a shallow dish.

Crush the Ritz crackers into fine crumbs and place them in another shallow dish.

Dip each chicken breast half into the yogurt, ensuring it is evenly coated.

Roll the yogurt-coated chicken breast in the cracker crumbs, pressing gently to adhere the crumbs to the chicken.

Place the coated chicken breasts in the prepared baking dish.

Bake in the preheated oven for 30 minutes.

After 30 minutes, flip the chicken breasts over and bake for an additional 30 minutes or until the chicken is cooked through and golden brown.

Serve hot.
