📝 Ingredients

For the Chicken & Mushrooms:

2½ lbs (about 1.1 kg) chicken breasts (4–5 large), cut into 1-inch strips

1½ tsp sea salt (plus more to taste)

¼ tsp black pepper (plus more to taste)

1 cup all-purpose flour (for dredging)

6 tbsp olive oil, divided

1 lb (450 g) white mushrooms, thickly sliced

1 medium onion, finely diced

3 garlic cloves, minced

For the Creamy Sauce:

3 tbsp unsalted butter

3 tbsp all-purpose flour

1½ cups chicken broth

1 tbsp fresh lemon juice

1 cup half-and-half (or ½ cup milk + ½ cup heavy cream)

👨‍🍳 Instructions

1. Preheat the Oven
   Preheat your oven to 350°F (175°C).
2. Prep & Season the Chicken
   Season chicken strips with salt and pepper, then dredge lightly in flour to coat evenly.
3. Sear the Chicken
   Heat 3 tbsp olive oil in a large skillet over medium heat. Sear the chicken in batches for 4–5 minutes per side until golden brown. Transfer the chicken to a baking dish.
4. Cook the Vegetables
   Add the remaining 3 tbsp olive oil to the skillet. Sauté mushrooms for 5 minutes until golden and soft, then remove and set aside. Add onion and garlic, cooking 2–3 minutes until tender and fragrant.
5. Make the Creamy Sauce
   Melt butter in the skillet. Stir in flour to form a roux, cooking for 1–2 minutes. Gradually whisk in chicken broth, then add lemon juice and half-and-half. Let it simmer gently until thickened.
6. Combine & Bake
   Return mushrooms to the sauce, stirring to coat. Pour the mushroom sauce over the chicken in the baking dish. Bake uncovered for 25–30 minutes, until the chicken is fully cooked and the sauce is bubbling.
7. Serve & Garnish
   Serve hot, optionally garnished with fresh parsley or thyme. Pair with mashed potatoes, rice, or crusty bread.
