Slow cooking allows the onions to soften and develop deep flavor while keeping the chicken incredibly juicy and tender.
Ingredients: (Serves 4)
3 large yellow onions, thinly sliced
2 tablespoons unsalted butter
1 1/2 pounds boneless, skinless chicken breasts
1 1/2 cups low-sodium beef broth
6–8 slices Swiss cheese
Optional: salt and black pepper to taste.
Directions:
Slice the onions thinly so they soften and melt into a rich onion sauce during cooking.
Add onions to the bottom of a 5–6 quart slow cooker and dot with butter.
Place chicken breasts on top of the onions in a single layer.
Slowly add the beef broth over the chicken and onions so everything braises evenly.
Cook on LOW for 4–5 hours or HIGH for 2½–3 hours until the chicken is tender and fully cooked.
Season lightly if desired, then top with Swiss cheese slices.
Cook on HIGH for 10–15 minutes until the cheese melts into a golden, gooey layer.
Spoon chicken with plenty of onions and broth over mashed potatoes, noodles, or garlic rice.
