French Onion Chicken Breasts

Ingredients

• 2 yellow onions, halved and thinly sliced
• ⅓ cup beef stock concentrate
• 16 oz chicken breast, cut into bite-size pieces
• 2 packets shredded mozzarella
• 2 teaspoons sugar
• 2 tablespoons cooking oil, plus more as needed
• Salt and black pepper

Instructions

1. Sauté the onions in oil until softened and lightly browned, 8–10 minutes. Add the sugar, stock concentrate, and 4 tablespoons water. Cook until the onions are deeply softened and jammy, 2–3 minutes more. Transfer the onions to a bowl.
2. Season the chicken with salt and pepper. Cook it in the same pan until browned and cooked through, about 5–6 minutes, turning as needed. Top with the onions and mozzarella during the last 1–2 minutes, cover, and cook until the cheese melts.
3. Serve the chicken with the jammy onions and melted mozzarella.

Notes

• Chicken is fully cooked at an internal temperature of 165°F.
