Ingredients
- 3 tablespoons vegetable oil
- 1½ pounds boneless, skinless chicken breasts, cut into strips
- 5 ounces oyster mushrooms, cleaned and sliced
- 4 ounces shiitake mushrooms, stems removed and sliced
- 8 ounces cremini (baby bella) mushrooms, sliced
- Salt and freshly ground black pepper, to taste

- ½ teaspoon ground sage
- 2 tablespoons all-purpose flour
- ½ cup dry white wine
- 2 cups chicken stock (preferably low sodium)
- ¼ cup heavy cream
- 1 tablespoon fresh parsley, chopped (for garnish)
Instructions
Heat 2 tablespoons of vegetable oil in a large skillet over medium-high heat. Add the chicken strips and season with salt and pepper. Sauté until golden and cooked through, about 5–7 minutes. Remove chicken from skillet and set aside.
2. Sauté the Mushrooms
In the same skillet, add the remaining 1 tablespoon of oil. Add oyster, shiitake, and cremini mushrooms. Cook for 5–7 minutes until mushrooms are browned and tender. Add the minced garlic and cook for another 1–2 minutes.
3. Make the Roux
Sprinkle the flour and ground sage over the mushroom mixture. Stir well and cook for 1 minute to eliminate raw flour taste.
4. Deglaze & Simmer
Pour in the white wine, scraping up any browned bits from the pan. Let it simmer for 2–3 minutes. Gradually add chicken stock while stirring. Bring to a simmer and cook for 5–6 minutes, allowing the sauce to thicken slightly.
5. Add Cream & Chicken
Stir in the heavy cream, then return the cooked chicken to the pan. Mix everything together well and adjust seasoning with salt and pepper if needed.
6. Bake the Casserole
Transfer the entire mixture into a greased casserole dish. Bake in a preheated oven at 375°F (190°C) for 15–20 minutes until bubbling and lightly golden. Garnish with chopped parsley before serving.
