Why You’ll Love This Chestnut Garlic Greek Chicken Alfredo
If you’re craving a hearty yet sophisticated chicken dinner, this recipe delivers. The combination of creamy Alfredo and herbaceous Greek flavors makes it a memorable dish. Plus, the addition of chestnut and mushroom pesto creates a sauce that clings beautifully to the tender chicken, offering rich umami in every mouthful.
What Kind of Mushrooms Should I Use?
Cremini or baby bella mushrooms are my favorite for this dish because of their deep, meaty flavor that pairs beautifully with the nutty chestnut garlic sauce. However, white button mushrooms or even wild mushrooms like chanterelles can be used if you want a slightly different flavor profile.

How To Make the Chestnut Garlic Greek Chicken Alfredo with Sage Potatoes & Mushroom Pesto Cream
Follow these steps to bring this comforting, gourmet meal to your table.
Step 1: Prepare the Potatoes
Peel and cube the Yukon gold potatoes. Toss with olive oil, chopped fresh sage, salt, and pepper. Roast at 400°F for about 25-30 minutes until golden and crisp.

Season chicken breasts with salt and pepper. Heat olive oil in a skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden brown and fully cooked. Remove and set aside.
Step 3: Create the Mushroom Pesto Cream
In the same skillet, sauté minced garlic and sliced mushrooms until fragrant and tender. Stir in chestnuts and a spoonful of pesto. Add Greek yogurt, heavy cream, and Parmesan, stirring until the sauce thickens and coats the back of a spoon.

Return the chicken to the skillet, spooning sauce over the top. Serve with the roasted sage potatoes on the side and drizzle extra mushroom pesto cream if desired.
