Why You’ll Love This Chestnut Garlic Greek Chicken Alfredo

It’s not just creamy; it’s layered with flavor from ingredients that sing in harmony. The chestnuts provide a seasonal nuttiness, the Greek yogurt keeps things fresh and light, and the mushroom basil pesto lends an unexpected gourmet touch. It’s cozy enough for a chilly night but sophisticated enough to serve at a dinner party.

If you’re someone who loves recipes that balance indulgence with vibrant, real-food ingredients, this is the one. Plus, you get everything on one plate: protein, carbs, and greens, all richly flavored and thoughtfully paired.

What Kind of Chicken and Potatoes Should I Use?

For the chicken, boneless skinless chicken breasts work best as they soak up the creamy Alfredo sauce while staying tender. You could also go for thighs if you prefer a juicier bite.

As for the potatoes, baby Yukon golds or red potatoes are perfect. Their creamy interiors and crisp skin after roasting with sage make them an ideal companion to the richness of the sauce and pesto. Aim for small, uniform sizes so they roast evenly and pick up all that herby flavor.

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

Step 1: Roast the Potatoes with Sage

Preheat your oven to 400°F (200°C). Toss halved baby potatoes with olive oil, salt, pepper, and fresh sage leaves. Spread on a baking sheet and roast until golden and crispy, about 30-35 minutes.

Step 2: Sear the Chicken

Season the chicken breasts with salt and pepper. Heat olive oil in a skillet over medium-high heat and sear the chicken until golden brown on both sides and cooked through. Set aside to rest before slicing.

Step 3: Make the Alfredo Sauce

In the same skillet, reduce the heat to medium. Add butter and minced garlic. Sauté until fragrant, then pour in heavy cream and Greek yogurt. Stir until smooth. Add Parmesan and stir again until melted and the sauce thickens. Add chopped roasted chestnuts and simmer for 2-3 minutes.

Step 4: Prepare the Mushroom Basil Pesto

In a food processor, pulse together chopped mushrooms, fresh basil, pine nuts, lemon juice, olive oil, salt, and pepper. Blend until smooth and set aside.

Step 5: Assemble the Plate

Place roasted sage potatoes on the side. Add sliced chicken topped with the creamy Alfredo sauce. Finish with a generous spoonful of mushroom basil pesto on top or swirled alongside for dipping.

How to Serve and Store This Chestnut Garlic Greek Chicken Alfredo

This rich and elegant dish serves about 4 people comfortably, making it ideal for a family dinner or small gathering. Serve it warm with the Alfredo sauce freshly poured and the mushroom basil pesto added just before bringing it to the table. The crisp sage potatoes are best when they’re hot and straight from the oven.

For storing, allow everything to cool to room temperature, then store the chicken and Alfredo sauce in one container and the potatoes separately to preserve their crispiness. Both will keep in the fridge for up to 3 days. Reheat the Alfredo sauce gently on the stove with a splash of milk or cream to bring it back to life. Avoid microwaving the potatoes to keep their texture intact—a few minutes in the oven will work better.
