Ingredients
- 1 1/2 pounds thin cut chicken breasts
- Salt and black pepper
- 6 tablespoons salted butter
- 3 yellow onions, thinly sliced
- 1/2 cup apple cider
- 3/4 cup dry white wine
- 3 cloves garlic, chopped
- 2 cups cremini mushrooms, sliced
- 2 tablespoons fresh thyme leaves
- 2 tablespoons chopped fresh sage
- 1 cup broth
- 3/4 cup heavy cream
- 6 slices French bread
- 1 cup shredded Gruyère cheese
Instructions
- Step 1: Preheat your oven to 425° F. Season the chicken breasts with salt and black pepper on both sides.
- Step 2: In a large oven-safe skillet, melt the butter over medium-high heat. Add the sliced onions and cook, stirring occasionally, until they soften and begin to caramelize, about 10 minutes.
- Step 3: Slowly add the apple cider, about 1/4 cup at a time, allowing it to cook into the onions before adding more.
- Step 4: Stir in the chopped garlic, sliced mushrooms, fresh thyme, and sage. Cook for another 3 to 4 minutes until the mushrooms begin to soften.
- Step 5: Add the seasoned chicken breasts to the skillet. Continue cooking for about 10 minutes, letting the onions brown deeply and the chicken start to cook through.
- Step 6: Pour in the white wine and broth. Turn the heat to high and bring the mixture to a low boil. Let it simmer for 10 minutes until the sauce slightly reduces.
- Step 7: Stir in the heavy cream and cook for another minute to combine everything well.
- Step 8: Arrange the French bread slices on a baking sheet. Toast them in the oven for about 10 minutes until they are dry and lightly crisp.
- Step 9: Place the toasted bread on top and around the chicken in the skillet. Sprinkle the shredded Gruyère cheese evenly over the bread.
- Step 10: Bake in the oven for 5 to 10 minutes, or until the cheese is melted and bubbly. Garnish with extra fresh thyme if desired before serving.
Tips & Variations
- Use thinly sliced onions and cook them slowly for the best caramelization and flavor depth.
- Substitute cremini mushrooms with shiitake or button mushrooms depending on availability.
- For a richer dish, swap out the heavy cream with half-and-half, but reduce simmering time to prevent curdling.
- Gluten-free bread can be used to make this dish suitable for gluten-sensitive diets.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently in a covered skillet over medium-low heat or in a 350° F oven until heated through. Avoid microwaving to keep the bread from becoming soggy.

FAQs
Can I use chicken thighs instead of chicken breasts?
Yes, boneless, skinless chicken thighs work well and add extra juiciness. Adjust cooking time to ensure they are fully cooked.
What type of white wine is best for this recipe?
A dry white wine like Sauvignon Blanc or Pinot Grigio is ideal, as it adds acidity without sweetness to balance the richness of the sauce.
