Ingredients Method

Ingredients

  

• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1 pound boneless, skinless chicken breasts, cut into small bite-size pieces
• 1 teaspoon kosher salt, divided
• 1/2 teaspoon black pepper, divided
• 4 cloves garlic, minced
• 3 cups low-sodium chicken broth
• 1 1/2 cups whole milk (or half-and-half for richer sauce)
• 8 ounces fettuccine or linguine, broken in half
• 3/4 cup freshly grated Parmesan cheese (plus more for serving)
• Pinch of red pepper flakes (optional)
• Juice of 1/2 lemon (optional, for brightness)
• Fresh parsley, chopped (for garnish)

4. Pour in chicken broth and milk.Stir in remaining salt and pepper. Add pasta, spreading it out so it’s mostly submerged.

6. Lower heat.Stir in Parmesan in small handfuls until melted and smooth. If sauce looks too thick, splash in a bit more milk or water; if too thin, simmer 1–2 minutes more.
7. Return chicken (and any juices) to the pot. Add red pepper flakes if using.Stir gently until warmed through, 1 minute.
8. Finish with a squeeze of lemon for brightness, taste, and adjust seasoning. Garnish with parsley and extra Parmesan. Serve hot.

Instructions

1. Heat a large deep skillet or Dutch oven over medium. Add butter and olive oil.
2. Season chicken with half the salt and pepper.

   Add to the pan and cook, stirring occasionally, until lightly golden and just cooked through, 4–5 minutes. Transfer to a plate.

3. Add garlic to the same pan. Cook 30 seconds until fragrant.
4. Pour in chicken broth and milk.

   Stir in remaining salt and pepper. Add pasta, spreading it out so it’s mostly submerged.

5. Bring to a gentle boil, then reduce to a lively simmer. Cook uncovered, stirring often to prevent sticking, 8–10 minutes until pasta is al dente and liquid has reduced to a silky base.
6. Lower heat.

   Stir in Parmesan in small handfuls until melted and smooth. If sauce looks too thick, splash in a bit more milk or water; if too thin, simmer 1–2 minutes more.

7. Return chicken (and any juices) to the pot. Add red pepper flakes if using.

   Stir gently until warmed through, 1 minute.

8. Finish with a squeeze of lemon for brightness, taste, and adjust seasoning. Garnish with parsley and extra Parmesan. Serve hot.

Storage Instructions

• Fridge: Store in an airtight container up to 3 days.
• Reheat: Warm gently on the stove with a splash of milk or water to loosen the sauce.

  Microwaving in short bursts works too—stir between bursts.

• Freezer: Not ideal, as cream sauces can separate. If you must, freeze up to 1 month and reheat with extra milk while whisking.

Health Benefits

• Protein-packed: Chicken provides lean protein to keep you full and support muscle repair.
• Calcium from dairy: Parmesan and milk contribute bone-supporting calcium.
• Customizable add-ins: Toss in spinach, peas, or broccoli for fiber, vitamins, and color.

What Not to Do

• Don’t crank the heat after adding cheese: High heat can cause sauce to split or turn gritty.
• Don’t skip stirring: Unstirred pasta can clump or stick to the pot.
• Don’t use pre-shredded Parmesan: Anti-caking agents prevent smooth melting. Freshly grated is key.
• Don’t overcook the chicken: Add it back just to warm so it stays juicy.

Alternatives

• Lighter sauce: Use 2% milk and add a spoon of light cream cheese for body.

• Different protein: Swap chicken for shrimp (cook 2–3 minutes until pink), Italian sausage, or rotisserie chicken.
• Veggie boost: Stir in baby spinach during the last minute or fold in thawed peas for sweetness.
• Pasta shapes: Penne, rotini, or linguine work well. Adjust liquid slightly as needed.
• Flavor spins: Add sun-dried tomatoes or try a Tuscan-style cream base like this favorite: Tuscan Cream Sauce Pasta With Spinach.

Can I use heavy cream instead of milk?

Yes. Heavy cream makes a richer, thicker sauce.

Replace the milk 1:1 and you may not need to reduce as long.

What if my sauce looks too thin?

Let it simmer another minute or two, stirring often. Cheese will also thicken as it melts, and the sauce will tighten slightly as it cools.

How do I avoid grainy Alfredo?

Use freshly grated Parmesan and lower the heat before adding it. Add cheese in small handfuls, stirring until melted before adding more.

Can I make it gluten-free?

Use your favorite gluten-free pasta and watch the liquid, as some GF pastas absorb more.

Add splashes of broth or milk as needed.

What vegetables go best here?

Spinach, peas, mushrooms, or steamed broccoli are all great. Stir them in during the final minutes so they stay bright and tender.
