Instructions
Prepare & Roast Sage-Infused Garlic Potatoes
Preheat your oven to 200°C (400°F). Line a large baking sheet with parchment paper.
In a large bowl, toss the potato wedges with 2 tbsp olive oil, smashed and roughly chopped garlic, fresh or dried sage, ½ tsp salt, and ¼ tsp black pepper. Ensure all potatoes are evenly coated.
Spread the seasoned potatoes in a single layer on the prepared baking sheet (do not overcrowd!).
Roast for 35-40 minutes, or until tender inside and deeply golden brown and crispy on the outside, flipping halfway through. Keep warm.
Marinate & Cook Garlic & Chestnut-Marinated Greek Chicken
While potatoes roast, in a bowl, combine the chicken slices with minced chestnuts, 3 cloves minced garlic, 1 tbsp olive oil, oregano, thyme, smoked paprika (if using), salt, and pepper. Toss to coat evenly. Let marinate for at least 30 minutes at room temperature, or longer in the refrigerator.
Heat a large skillet over medium-high heat. Add the marinated chicken slices (cook in batches if necessary to avoid overcrowding). Cook for 4-6 minutes per side, or until cooked through and nicely browned with a flavorful crust. Remove chicken from skillet and set aside, tented with foil.
Prepare Rich Chestnut Mushroom Alfredo with Creamy Basil Pesto
In the same large skillet (or a separate saucepan), melt 2 tbsp unsalted butter over medium heat.
Add the sliced cremini mushrooms and sauté for 5-7 minutes, stirring occasionally, until they are browned and have released their moisture.
Add 4 cloves minced garlic and the 120g (½ cup) roughly chopped chestnuts. Sauté for another 1-2 minutes until fragrant.
Pour in 350ml (1 ½ cups) heavy cream and 120ml (½ cup) chicken broth. Bring to a gentle simmer, stirring occasionally, scraping up any browned bits from the bottom of the pan.
Reduce heat to low. Gradually whisk in 240ml (1 cup) grated Parmesan cheese, a handful at a time, until the cheese is melted and the sauce is smooth and lusciously creamy. Season with salt and freshly cracked black pepper to taste.
Creamy Twist: Stir in the 60ml (¼ cup) basil pesto. Whisk until fully combined, creating a beautifully green-tinted, fragrant sauce. If the sauce is too thick, thin with a splash of warm water or broth. Keep warm over very low heat.
Assemble & Serve
Divide the Sage-Infused Crispy Garlic Roasted Potatoes among serving plates.
Spoon generous portions of the Rich Chestnut Mushroom Alfredo with Creamy Basil Pesto onto each plate.
Arrange the Garlic & Chestnut-Marinated Greek Chicken Slices over the sauce.
Serve immediately and savor every exquisite bite of this complex, flavorful, and incredibly satisfying meal!
Tips for Success
Chestnuts: Jarred or canned cooked chestnuts are a convenient shortcut. If using fresh, they require boiling/roasting and peeling. Minced chestnuts in the marinade add subtle flavor and moisture.
Mushroom Browning: Allowing the mushrooms to brown well before adding liquids deepens their umami flavor and contributes significantly to the sauce’s richness.
Pesto Quality: A good quality basil pesto (homemade or store-bought) will shine through in the sauce.
Potato Crispiness: Ensure the potatoes are spread in a single layer on the baking sheet for maximum crispiness.
Chicken Slicing: Slicing chicken thinly helps it cook faster and absorb marinade better.
