Why You’ll Love This Chestnut Garlic Greek Chicken Alfredo

It’s creamy, but not overly rich. Savory, yet subtly sweet from the chestnuts. The chicken is seasoned with Greek herbs and seared to golden perfection, giving every bite a punch of flavor. The sage potatoes bake up crispy on the outside and tender within, making them the ideal companion to the glossy mushroom basil pesto cream.

Whether you’re hosting a cozy dinner or treating yourself on a weeknight, this dish delivers both comfort and gourmet appeal.

What Kind of Chicken Should I Use?

Boneless skinless chicken thighs are our top pick here. They have more flavor than breast meat and stay juicy, even when cooked in the creamy alfredo base. However, you can also use boneless chicken breasts if that’s what you have on hand—just be careful not to overcook.

Rotisserie chicken could even work in a pinch. Just shred it and add it during the final simmer in the cream sauce. The idea is to keep the flavors layered and the texture tender and luscious.

How To Make the Chestnut Garlic Greek Chicken Alfredo with Sage Potatoes & Mushroom Basil Pesto Cream

Step 1: Roast the Sage Potatoes

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

Step 2: Prepare the Chicken

Season the chicken thighs with Greek seasoning, salt, and pepper. In a large skillet, sear them in olive oil over medium heat for 6-7 minutes per side until fully cooked and golden. Set aside and slice or shred as desired.

Step 3: Sauté the Mushrooms

In the same skillet, add butter and sauté sliced mushrooms with a pinch of salt until browned and tender. Add minced garlic and cook another minute.

Step 4: Make the Alfredo Base

Pour in the heavy cream and bring to a low simmer. Stir in grated parmesan cheese and the Alfredo sauce. Simmer gently for 5-7 minutes until thickened.

Step 5: Create the Pesto Cream

In a blender, combine roasted chestnuts, basil, lemon juice, and a splash of the Alfredo base. Blend until smooth. Stir this pesto cream back into the skillet.

Step 6: Combine Everything

Add the chicken back into the sauce and let it warm through. Serve over the roasted sage potatoes and top with extra basil or parmesan if desired.

Serving and Storing Chestnut Garlic Greek Chicken Alfredo

This dish is hearty and filling, easily serving 4 to 6 people depending on portion sizes. It’s best served hot, with the chicken and sauce poured generously over a bed of crispy sage potatoes. Garnish with extra basil or a dusting of parmesan for a restaurant-worthy finish.

If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. The sauce may thicken upon cooling, so reheat gently on the stovetop or microwave with a splash of cream or milk to loosen it back to its silky texture.
