Lunch10 min1564 cal / serving

Imagine all the rich, savory flavors of classic French onion soup transformed into a hearty weeknight dinner. Tender chicken cutlets are seared until golden, then topped with buttery caramelized onions simmered in beef stock and fresh thyme. A blanket of gooey Swiss cheese melts over the top, creating that irresistible, stringy pull we all love.

To soak up every last drop of the savory sauce, we’ve included crusty garlic bread made from a demi-baguette. On the side, roasted carrots get a bright squeeze of lemon for a fresh, vibrant balance. This dish is pure comfort, ready in under an hour.

Instructions

  1. Preheat your oven to 425°F. Line a baking sheet with foil.
  2. Peel and slice the onion into thin strips. Peel the carrots and cut them into ½-inch thick rounds. Pick the thyme leaves from the stems.
  3. In a small bowl, mix the garlic powder with 1 tablespoon softened butter and a pinch of salt. Set aside.
  4. Cut the demi-baguette in half lengthwise, then slice each half crosswise to make 4 pieces. Spread the garlic butter onto the cut sides.
  5. On the prepared baking sheet, toss the carrot rounds with 1 tablespoon olive oil, salt and pepper. Roast for 20-25 minutes, until tender and lightly browned.
  6. Meanwhile, heat 1 tablespoon olive oil in a large skillet over medium-high heat. Season the chicken cutlets with salt and pepper. Sear for 3-4 minutes per side, until golden and cooked through. Transfer to a plate and cover loosely.
  7. Reduce the heat to medium-low. Add the remaining 2 tablespoons butter to the skillet. Add the sliced onion and a pinch of salt. Cook, stirring occasionally, for 10-12 minutes until soft and caramelized.
  8. Stir in the sugar, half the thyme leaves and the beef stock concentrate (dissolved in ¼ cup water). Simmer for 2-3 minutes until slightly thickened.
  9. Return the chicken to the skillet, spooning the onions over the top. Lay the Swiss cheese slices over the chicken. Cover the skillet and cook for 2-3 minutes until the cheese melts.
  10. While the cheese melts, place the garlic bread pieces on a separate baking sheet and toast in the oven for 5-7 minutes until golden.
  11. Squeeze the lemon juice over the roasted carrots and toss gently.
  12. Serve the cheesy chicken with garlic bread and lemony carrots on the side. Garnish with remaining thyme leaves.

Recipe Tips

For deeper caramelized onions, cook them slowly over medium-low heat, stirring occasionally.

If you don’t have a lid for your skillet, cover it with a large piece of foil to melt the cheese.

The carrots can be roasted while you prepare the chicken and onions to save time.

FAQ

Can I use a different cheese instead of Swiss?

Yes, Gruyère or provolone would work well for a similar melty, nutty flavor.

How do I prevent the chicken from drying out?

Don’t overcook the chicken; sear until just cooked through and let it rest before adding to the onion sauce.

Can I make this dish ahead of time?

It’s best served fresh, but you can prepare the caramelized onions and roasted carrots in advance. Reheat gently before serving.
