  • 1 tbsp olive oil
  • 2 large chicken breasts, sliced in half lengthwise
  • Salt & pepper to taste
  • 1 tsp olive oil
  • 4 yellow onions, sliced
  • 2 tsp flour
  • 2 tbsp red wine
  • 1/2 cup beef broth
  • 1/2 cup Swiss cheese, grated

Oven-roasted broccoli

  • 1 head broccoli, cut into florets
  • 1 tsp olive oil
  • 2 cloves garlic minced
  • 1/4 tsp each salt & pepper


  • Preheat oven to 425 F. Add 1 tbsp olive oil to a large skillet over med-high heat. Meanwhile, slice chicken in half lengthwise then season with salt and pepper.
  • Saute chicken for 4-5 minutes each side, then remove from heat and wipe pan clean with a paper towel. Add 1 tsp olive oil to skillet then add onions and cook for 10 minutes, stirring occasionally until onions brown.
  • Meanwhile, toss broccoli with 1 tsp olive oil, garlic, salt and pepper on a parchment-lined sheet pan. Bake for 8-10 minutes until broccoli is tender.
  • Once onions are softened and somewhat browned, mix in flour and then add red wine and beef broth, mixing well to combine.
  • Add chicken back to skillet and cover with onion mixture, then top with cheese and put lid on top of skillet to let cheese melt, about 2 minutes.
  • Serve chicken with broccoli and enjoy!



When cutting the onions, turn on the fan or chill the onions before chopping them to prevent your eyes from watering.
Try serving the onion sauce with another protein like pork chops, steak or fish.
Store the leftovers in the fridge for up to 5 days. Reheat in the microwave for a few minutes or in the oven at 350 F for 20 minutes.
Freeze this recipe for up to 3 months. Defrost in the fridge overnight then reheat as normal.
