Total time: 1 h
Cuisine: Greek
Ingredients: 4 boneless skinless chicken thighs; 1 cup cooked chestnuts; 1 head roasted garlic; 1 cup heavy cream; 3/4 cup grated Parmesan cheese; 1 1/2 pounds Yukon Gold potatoes, chopped; 1 tablespoon fresh sage, chopped; 1 cup mushrooms, sautéed; 1/2 cup fresh basil leaves; 3 tablespoons olive oil; 2 tablespoons lemon juice; 1 teaspoon salt; 1/2 teaspoon black pepper

This is not your average chicken Alfredo. Imagine juicy Greek-marinated chicken thighs, seared to golden perfection and smothered in a rich, nutty chestnut garlic Alfredo sauce. Then you add crispy-on-the-outside sage-roasted potatoes and top it all off with a drizzle of earthy mushroom basil pesto. It’s cozy comfort food with Mediterranean flair and an elegant twist.

The flavors in this dish work in layers. First, the Greek marinade brings in citrusy tang and herbs that infuse the chicken with bold character. Then comes the Alfredo, made heartier and deeper with roasted garlic and sweet chestnuts. The sage potatoes are the grounding balance with their buttery, herbal warmth, while the mushroom basil pesto gives the final earthy kick that ties everything together.

Why You’ll Love This Chestnut Garlic Greek Chicken Alfredo

This recipe is for the ones who want something both comforting and elevated. It turns basic chicken and potatoes into something you’d proudly serve at a dinner party but also crave after a long weekday. The chestnut garlic sauce alone is worth making a double batch for later. With minimal fuss and maximum flavor, this meal checks all the boxes.

It also plays beautifully with seasonal ingredients. Chestnuts in the fall, basil from summer’s end, and that creamy Alfredo vibe that somehow feels just right all year long. And it makes enough to feed a small group with ease, so it’s a favorite for when you’re hosting without the stress.

What Kind of Potatoes and Chicken Should I Use?

For the potatoes, Yukon Golds work best here because they get deliciously crisp on the outside but stay tender inside. Red potatoes can be a good substitute, but avoid russets—they tend to fall apart with roasting.

As for the chicken, go for boneless, skinless chicken thighs if you want maximum flavor and tenderness. Breasts can work too, but they cook faster and can dry out if you’re not careful. Thighs hold the marinade better and stay juicy, making them ideal for the sear-then-sauce process in this dish.

Ingredients for the Chestnut Garlic Greek Chicken Alfredo

This dish may sound like a mouthful, but the ingredient list is surprisingly approachable. Each component has its own standout flavor, and together they build something special. From the chestnuts that bring a subtle sweetness to the pesto that brings a punch of herby depth, every element earns its spot.

Chicken thighs: Juicy and flavorful, thighs are ideal for absorbing the Greek marinade and holding up to the Alfredo sauce.
Chestnuts: These add a natural sweetness and creaminess when blended into the sauce, creating a more complex Alfredo.
Roasted garlic: Roasting softens the garlic and brings out a sweet, caramelized flavor that pairs beautifully with chestnuts.
Heavy cream: The base for the Alfredo, bringing that luscious, velvety texture.
Parmesan cheese: Adds nutty saltiness to balance the sweetness of chestnuts.
Yukon Gold potatoes: They roast up with crispy edges and tender centers, perfect for soaking up pesto.
Fresh sage: Earthy and aromatic, sage gives the potatoes a cozy, herbed finish.
Mushrooms: Used in the pesto, they provide umami depth and a satisfying, meaty texture.
Fresh basil: Bright and herbal, basil lifts the richness of the sauce and ties the pesto together.
Olive oil: Used in marinades, roasting, and pesto to bring everything together with smoothness.
Lemon juice: Key to the Greek marinade, adding brightness and cutting through richness.
Salt and black pepper: Essential for balancing and enhancing all the flavors.

How To Make the Chestnut Garlic Greek Chicken Alfredo

Step 1: Marinate the Chicken

Start by whisking olive oil, lemon juice, minced garlic, salt, pepper, and a pinch of dried oregano in a bowl. Coat the chicken thighs in this mixture, cover, and refrigerate for at least 30 minutes or overnight for the best flavor.

Step 2: Roast the Potatoes

Preheat your oven to 400°F. Toss chopped Yukon Gold potatoes with olive oil, chopped sage, salt, and pepper. Spread them out on a baking sheet and roast for 30-35 minutes, flipping once, until crispy and golden.

Step 3: Make the Chestnut Garlic Alfredo

While the potatoes roast, heat olive oil in a saucepan over medium heat. Add roasted garlic and peeled, cooked chestnuts. Sauté until fragrant, then pour in the heavy cream. Let it simmer gently, then blend the mixture until smooth. Return to the pan, stir in grated Parmesan, and season to taste.

Step 4: Sear the Chicken

In a hot skillet, sear the marinated chicken thighs for 5-6 minutes per side until cooked through and beautifully browned. Remove and let them rest before slicing.

Step 5: Make the Mushroom Basil Pesto

In a food processor, blend sautéed mushrooms, fresh basil, olive oil, and a small amount of Parmesan. Pulse until chunky-smooth. Season with salt and pepper to taste.

Step 6: Bring It All Together

Slice the chicken and serve it over a bed of roasted sage potatoes. Spoon the chestnut garlic Alfredo generously over the top, and finish with dollops of mushroom basil pesto. Serve warm and savor every bite.

How to Serve and Store This Chicken Alfredo Dish

This hearty dish is perfect for a sit-down dinner when you want something special without the formality. Serve it plated with the chicken fanned out over the potatoes, drizzled generously with the Alfredo, and pesto spooned over like a finishing flourish. For added color, sprinkle a few fresh basil leaves or a dusting of lemon zest on top. It looks impressive, but the flavors are what truly shine.

This recipe serves 4 to 5 people generously, making it ideal for a small gathering or leftovers for lunch the next day. If you do have leftovers, store them in an airtight container in the fridge for up to 3 days. The Alfredo sauce may thicken, but a splash of cream or broth when reheating will bring it right back to life.
