French Onion Chicken 
Ingredients:
4 boneless skinless chicken breasts
2 teaspoons olive oil
2 medium yellow onions, thinly sliced
1 tablespoon balsamic vinegar (or more as needed)
1 tablespoon Worcestershire sauce
½ teaspoon dried thyme or 1 teaspoon fresh thyme leaves
3 ounces Gruyère cheese, coarsely grated (about 1 cup)
½ cup all-purpose flour (or gluten-free flour mix*)
1 teaspoon kosher salt
Pepper (to taste)
½ teaspoon paprika
2 teaspoons unsalted butter
1/2 cup chicken broth
Instructions:
Prepare Onions:
In a large nonstick skillet, heat the oil over medium heat.
Add the onions and 1/4 teaspoon salt, increase to medium-high, and cook, stirring frequently, until they start to brown around the edges.
Turn the heat to medium-low and add the balsamic vinegar, Worcestershire sauce, and thyme. Continue to cook, stirring occasionally, for 20 to 25 minutes, or until the onions are very tender. Add 1 to 2 tablespoons of water to deglaze. Set aside and wipe out the skillet.
Prepare Chicken:
Season to taste with 1 teaspoon salt and black pepper and set aside.
In a wide, shallow bowl, whisk together the flour, pinch of salt, and paprika.
Set a large nonstick skillet over medium heat and melt 1 teaspoon butter.
Dredge two of the chicken cutlets in the seasoned flour, then shake off the excess and lay them side by side in the pan.
Cook the chicken for 3 minutes, or until lightly browned, then flip and cook for 3 more minutes. Set aside on a dish and repeat with the remaining butter and chicken. Set aside.
Assemble and Cook:
Combine the broth and 1 tablespoon of the flour mixture and mix, add it to the skillet and whisk on low heat, 1 minute, until it thickens. Toss the rest of the flour out.
Return the chicken to the skillet, top with onions and cheese and cover. Cook low 3 to 5 minutes, until the cheese is melted and bubbling.
Enjoy your delicious French Onion Chicken!
