For the Chicken

• Chicken Breasts or Thighs – Use about 1.5 lbs. Both work beautifully; breasts stay lean and tender, while thighs add a bit more richness.
• Parmesan Cheese – Freshly grated cheese creates that golden, flavorful crust on the chicken.
• Oregano – Adds a warm, earthy Italian note to the seasoning.
• Salt & Fresh Cracked Black Pepper – Essential for bringing out the flavors.

For the Alfredo Sauce

• Butter – The base of the sauce, adding silky texture and rich flavor.
• Garlic – Freshly minced garlic infuses the sauce with deep, savory aroma.
• All-Purpose Flour – Helps thicken the sauce slightly for that creamy consistency.
• Heavy Whipping Cream – The heart of a true Alfredo—luxuriously smooth and rich.
• Sour Cream – Adds a little tang and balance to the richness.
• Parmesan Cheese (Fresh & Dry) – A mix of both types gives the sauce body, saltiness, and depth.
• Salt & Pepper – Adjust to taste once the sauce is creamy and smooth.

For the Pasta

• Fettuccine – Classic choice for Alfredo; its wide, flat shape holds the sauce beautifully.

Ingredients

Pasta

• 16 oz fettuccine

Chicken

• 1.5 lbs chicken breasts or thighs
• ½ cup grated Parmesan cheese
• 2½ tsp dried oregano
• Salt, to taste
• Fresh cracked black pepper, to taste

Alfredo Sauce

• 2 tbsp unsalted butter
• 2 garlic cloves, minced or pressed
• 1 tbsp all-purpose flour
• 2 cups heavy whipping cream
• ¼ cup sour cream
• ½ cup freshly grated Parmesan cheese
• ½ cup dry Parmesan cheese
• Salt and black pepper, to taste

Instructions

1. Cook the Pasta

Cook fettuccine according to package directions until al dente. Avoid overcooking to keep it firm. Drain and set aside.

2. Bake the Chicken

1. Preheat oven to 450°F (232°C). Grease a rimmed baking sheet.
2. Trim excess fat from chicken. Season both sides with salt, pepper, and oregano.
3. Generously coat both sides with grated Parmesan cheese.
4. Arrange chicken on the baking sheet and bake for 15–20 minutes, depending on thickness.
5. Let the chicken rest for 5 minutes, then slice against the grain.

3. Make the Alfredo Sauce

1. While the chicken and pasta cook, prepare the sauce. Measure all ingredients before you start.
2. In a medium heavy-bottomed saucepan, melt the butter over medium heat.
3. Add the minced garlic and cook until fragrant.
4. Sprinkle in flour and stir until combined.
5. Gradually whisk in the heavy whipping cream, stirring constantly.
6. Warm gently (do not boil). Once hot, whisk in sour cream, both types of Parmesan, salt, and pepper.
7. Reduce heat to medium-low and cook for about 5 minutes, stirring often, until the cheese melts and the sauce thickens.

4. Combine and Serve

Toss the cooked fettuccine with the Alfredo sauce and top with sliced chicken.
Garnish with fresh parsley and extra Parmesan cheese if desired.

 

Tips & Notes

Gluten-Free Options

• Flour: Substitute the all-purpose flour with a 1:1 gluten-free flour blend.
• Pasta: Use your favorite gluten-free fettuccine. Tinkyada is an excellent brand with a great texture.

Storage

Store Alfredo sauce in an airtight glass jar in the refrigerator for up to 3–5 days.

Reheating

Reheat gently in a saucepan over medium-low heat, stirring often.
If using a microwave, heat in 30–40 second intervals at low power, stirring in between.

Stovetop Chicken Option

Cook seasoned chicken in a preheated skillet over medium to medium-low heat for 4–7 minutes per side, until internal temperature reaches 165°F (74°C).

Save

1. My sauce split! How do I fix it?

Don’t panic — it happens to the best of us. Just turn the heat down and whisk in a splash of the pasta cooking water. The starch helps bring everything back together and makes the sauce silky again. Crisis averted.

2. Can I use a different pasta?

Absolutely! Fettuccine is traditional (and perfect for soaking up that creamy sauce), but linguine, penne, or even spaghetti will work just fine. Use what’s in the pantry — Alfredo doesn’t discriminate.

3. How do I keep the chicken juicy?

The secret? Don’t overcook it. Pull it off the heat when it hits 165°F / 74°C, then let it rest for a few minutes before slicing. That’s when all those tasty juices stay locked inside.

4. Can I make it ahead?

You can cook the chicken a day ahead and store it in the fridge. The sauce, though, is best made fresh — creamy sauces just don’t love reheating. If you’ve got leftovers, warm them gently on the stove with a splash of milk or cream to loosen things up.

5. My sauce is too thick / too thin — what now?

If it’s too thick, add a little pasta water and stir until it’s glossy and smooth again. Too thin? Let it simmer for a minute or two and it’ll thicken right up. Just keep the heat gentle — boiling cream is a no-go.
