Description
A hands-off slow cooker recipe featuring tender chicken breasts cooked with caramelized onions, beef broth, and melted Gruyère or Swiss cheese for a rich, comforting meal.
Ingredients
- 4 large yellow onions, thinly sliced (about 600g / 1.3 lbs)
- 4 boneless, skinless chicken breasts (about 1.5 lbs / 700g)
- 2 cups beef broth (480ml)
- 3 cloves garlic, minced (about 1 tablespoon)
- 3 tablespoons butter (45g)
- 1 tablespoon Worcestershire sauce (15ml)
- 1 teaspoon dried thyme
- 1½ cups shredded Gruyère or Swiss cheese (about 150g)
- Salt and black pepper, to taste
- Optional: Fresh parsley for garnish
- Optional: 1 cup sliced mushrooms (for sauté step)
- Optional: Baby spinach or kale (added last 15 minutes)
Instructions
- Melt butter in a large skillet over medium-low heat. Add thinly sliced yellow onions and a pinch of salt. Cook slowly, stirring occasionally, until golden brown and caramelized (about 15-20 minutes).
- Near the end of caramelizing, stir in minced garlic, dried thyme, and Worcestershire sauce. Cook for another minute until fragrant, then remove from heat.
- Season chicken breasts with salt and pepper on both sides.
- Place chicken breasts in the bottom of the slow cooker. Spoon caramelized onions over the chicken, including garlic and flavorful bits.
- Pour beef broth over the chicken and onions.
- Cover and cook on high for 4-5 hours or on low for 7-8 hours until chicken is tender and cooked through.
- About 15 minutes before serving, sprinkle shredded Gruyère or Swiss cheese evenly over the chicken and onions. Cover and let cheese melt.
- Optional: For a golden crust, transfer chicken and onions to an oven-safe dish and broil for 2-3 minutes, watching closely to avoid burning.
- Garnish with fresh parsley if desired and serve over mashed potatoes, egg noodles, rice, or crusty bread.
Notes
[‘Caramelize onions low and slow for best flavor and sweetness.’, ‘Use beef broth instead of chicken broth for richer flavor.’, ‘Add cheese near the end to melt perfectly without drying out.’, ‘Broil cheese topping for a crispy golden crust if desired.’, ‘Optional additions: mushrooms during sauté, spinach or kale last 15 minutes.’, ‘Leftovers keep well in the fridge for up to 4 days; reheat gently with added liquid.’, ‘Does not freeze well due to cheese and broth separation.’, ‘Chicken thighs can be used but adjust cooking time accordingly.’, ‘Instant Pot method: sauté onions and garlic, pressure cook chicken and broth 10 minutes, natural release, add cheese and melt with sauté.’]
