Fresh Sage: Infused into the potato roast for a herbal, savory aroma.
Mushrooms (Cremini or Baby Bella): Pan-seared for a meaty, umami depth.
Fresh Basil: Blended into the pesto to brighten and balance the dish.

How To Make the Chestnut Garlic Greek Chicken Alfredo

Step 1: Marinate & Grill the Chicken

Mix Greek yogurt, olive oil, roasted garlic paste, chopped chestnuts, salt, and pepper. Coat chicken breasts thoroughly and let them marinate for at least 30 minutes. Sear on a hot grill pan until golden with charred edges, then finish in the oven until cooked through.

Step 2: Roast the Sage Potatoes

Toss halved baby potatoes with olive oil, salt, pepper, and chopped sage. Roast in a 425°F oven until they’re crispy on the outside and fluffy inside, about 30 minutes.

Step 3: Sauté the Mushrooms

In a skillet, melt butter and a dash of olive oil, then add sliced mushrooms. Cook until browned and caramelized. Season lightly with salt and pepper.

Step 4: Make the Pesto Alfredo Sauce

In a saucepan, simmer heavy cream with roasted garlic and Parmesan. In a blender, mix fresh basil, olive oil, and Parmesan to create a pesto. Combine both mixtures and whisk until smooth and creamy.

Step 5: Assemble and Serve

Slice the grilled chicken and plate alongside sage potatoes and sautéed mushrooms. Drizzle generously with the warm basil pesto Alfredo sauce. Garnish with extra herbs or Parmesan if desired.

Serving and Storing Your Chicken Alfredo Delight

Serve this dish hot with the sauce poured generously over the chicken and vegetables. It pairs beautifully with a glass of crisp white wine or a light citrusy sparkling water. For added flair, sprinkle some extra roasted chestnuts or a few fresh basil leaves on top.

Leftovers can be stored in an airtight container for up to 3 days in the refrigerator. When reheating, do so gently on the stovetop or in the microwave to keep the sauce smooth and prevent drying out the chicken. You can add a splash of cream or milk to revive the sauce consistency.

Frequently Asked Questions

How can I make this dish dairy-free?

Use full-fat coconut milk for the Alfredo and swap Parmesan with a dairy-free cheese alternative. Make sure your Greek yogurt substitute is plant-based.

Can I prep anything ahead of time?

Absolutely. You can roast the chestnuts, marinate the chicken, and even prep the pesto sauce up to a day in advance.

What protein alternatives can I use?

Grilled tofu, turkey breast, or shrimp work beautifully with the same marinade and sauce.

Can I freeze this dish?

While the chicken and potatoes freeze well, the Alfredo sauce may separate when thawed. If freezing, do so without the sauce and make it fresh when reheating.

What sides go well with this meal?

A simple arugula salad or roasted asparagus make great companions without overshadowing the main dish.
