What Kind of Chicken Should I Use?

Boneless, skinless chicken breasts are ideal here because they cook evenly and absorb the creamy sauce so well. You can also use chicken thighs if you prefer darker meat and a juicier bite. Make sure to pound the breasts to an even thickness for a perfect sear.

Ingredients for the Creamy Garlic Mushroom Alfredo Chicken & Potatoes

• Chicken Breasts: The star protein. They cook up golden on the outside and remain juicy on the inside.
• Baby Potatoes: Roasted to crispy perfection. Their creamy centers pair so well with the Alfredo sauce.
• Mushrooms: Add a savory umami flavor and depth to the Alfredo sauce.
• Garlic: Essential for bold, aromatic flavor in both the sauce and chicken.
• Heavy Cream: The base of our Alfredo sauce. Rich, velvety, and perfect for coating.
• Parmesan Cheese: For salty, nutty depth that thickens the sauce beautifully.
• Butter: Used to sauté the mushrooms and garlic and adds richness to the sauce.
• Olive Oil: Helps roast the potatoes to crispy golden brown and sear the chicken evenly.
• Basil Pesto: Swirled into the Alfredo for a fresh herby punch.
• Salt & Pepper: For seasoning every layer just right.

How To Make the Creamy Garlic Mushroom Alfredo Chicken & Potatoes

Step 1: Roast the Potatoes

Preheat your oven to 425°F (220°C). Halve the baby potatoes and toss them in olive oil, salt, and pepper. Spread them out on a baking sheet and roast for 25-30 minutes, flipping halfway through until golden and crispy.

Step 2: Sear the Chicken

While the potatoes roast, season chicken breasts with salt and pepper. Heat a bit of olive oil in a skillet over medium-high heat. Sear chicken on each side for 5-6 minutes until golden brown and cooked through. Remove and set aside.

Step 3: Sauté the Mushrooms & Garlic

In the same skillet, melt butter and add sliced mushrooms. Cook until browned and tender, about 6-8 minutes. Add minced garlic and sauté until fragrant, about 1 minute.

Step 4: Make the Alfredo Sauce

Lower the heat to medium and pour in heavy cream. Stir in grated Parmesan cheese until smooth and creamy. Let the sauce simmer gently for 5 minutes to thicken. Season with salt and pepper to taste.

Step 5: Add Basil Pesto

Stir in a generous spoonful of basil pesto to elevate the sauce with herby brightness. Adjust seasoning as needed.

Step 6: Combine and Serve

Return the chicken to the skillet and spoon sauce generously over the top. Let it simmer for 2-3 more minutes. Serve the chicken and sauce over the crispy roasted potatoes.

How to Serve and Store This Creamy Dish

Serve this dish immediately while hot—ideally on a pre-warmed plate so the sauce stays silky. Garnish with a sprinkle of extra Parmesan or a light drizzle of pesto if you’re feeling fancy. It pairs well with a side salad or green beans for balance.

To store leftovers, place them in an airtight container in the fridge for up to 3 days. Reheat gently on the stove over low heat, adding a splash of cream or milk to bring the sauce back to life. The potatoes can be crisped up again in the oven or air fryer.

Frequently Asked Questions

What can I substitute for heavy cream?

You can use half-and-half or even a mix of whole milk and cream cheese, though the sauce won’t be as rich. Coconut cream works if you need a dairy-free option.

Can I use a different type of cheese?

Yes! Asiago, Romano, or a blend of Italian cheeses will give you a slightly different but still delicious flavor profile.

Can this dish be made ahead of time?

Absolutely. You can cook the chicken and potatoes a day in advance, then reheat everything in the Alfredo sauce just before serving.

What mushrooms work best?

Cremini or baby Bella mushrooms are ideal, but white button mushrooms will also work. You could even go fancy with a mix of wild mushrooms.

Can I make it spicy?

Definitely. Add a pinch of red pepper flakes to the Alfredo sauce or season the chicken with a little cayenne for a kick.

Is this dish gluten-free?

Yes, naturally gluten-free as long as your pesto and Parmesan are verified gluten-free. Just double-check your labels.
