1. 1. Prepare the Mushrooms: Gently wipe the mushrooms clean with a damp paper towel. Carefully remove the stems by twisting or gently pulling them out. Finely chop the mushroom stems and set them aside. This ensures the mushrooms are ready for stuffing and helps prevent them from becoming watery during baking.

2. 2. Preheat and Saute: Preheat your oven to 375 F (190 C). In a medium skillet over medium heat, add a drizzle of olive oil. Saute the chopped mushroom stems for 3-5 minutes, until softened. This step adds an extra layer of mushroom flavor to the filling.

3. 3. Create the Filling: In a mixing bowl, combine the softened cream cheese, shredded cooked chicken, buffalo wing sauce, ranch dressing, and the sauteed mushroom stems. Mix everything well until fully combined and creamy. Season with salt and black pepper to taste.

4. 4. Stuff the Mushrooms: Arrange the hollowed mushroom caps on a baking sheet. Using a small spoon or your fingers, generously fill each mushroom cap with the buffalo chicken mixture. Don’t be shy; pack them full!

5. 5. Add Cheese Topping: Sprinkle the shredded cheddar cheese evenly over the top of each stuffed mushroom. This will create a delicious, golden-brown crust as they bake.

6. 6. Bake Until Golden: Place the baking sheet in the preheated oven and bake for 20 minutes, or until the mushrooms are tender, the filling is heated through, and the cheese is melted and lightly golden brown. You’ll see the edges of the mushrooms start to soften and darken slightly.

7. 7. Garnish and Serve: Carefully remove the baking sheet from the oven. Drizzle a little extra buffalo sauce over the hot mushrooms, if desired, and sprinkle with fresh chopped chives or green onions for a pop of color and freshness. Serve immediately.
