Ingredients

(Adjust amounts using the scale feature)

12 ounces fettuccine (or your favorite pasta shape)
1 tablespoon extra virgin olive oil or butter
4 garlic cloves, minced or pressed
3 tablespoons all-purpose flour
1 cup chicken stock
1 cup low-fat milk (such as 1%)
3/4 cup freshly grated Parmesan cheese
1/2 teaspoon salt
1/4 teaspoon black pepper
Optional for serving: chopped fresh parsley, extra Parmesan

Instructions

1. Cook the Pasta

Bring a large pot of generously salted water to a boil. Cook the pasta until al dente, according to package directions. Drain and set aside.

2. Make the Light Alfredo Sauce

While the pasta cooks, heat olive oil (or melt butter) in a large sauté pan over medium-high heat. Add the garlic and sauté for about 1 minute, stirring occasionally, until fragrant.

Sprinkle in the flour and stir constantly for 1 more minute to cook off the raw flour taste.

3. Add Liquids and Thicken

Slowly pour in the chicken stock while whisking to combine into a smooth mixture. Then whisk in the milk and bring the sauce to a gentle simmer. Cook for 1–2 minutes, whisking frequently, until slightly thickened.

4. Finish the Sauce

Lower the heat to medium-low. Stir in the grated Parmesan, salt, and black pepper until the cheese is fully melted and the sauce is creamy.

5. Combine Pasta and Sauce

Add the drained pasta to the sauce and toss gently until all the noodles are well coated.

6. Serve

Serve immediately, garnished with chopped parsley and additional Parmesan if desired.

Tips

Whisk constantly when adding liquids to prevent lumps.
Use freshly grated Parmesan — it melts better and gives a richer flavor than pre-shredded.
Don’t overcook the sauce — once thickened and the cheese is melted, it’s ready.
Toss the pasta in the sauce while still hot to help it absorb the flavor.

FAQs

Can I use whole milk or non-dairy milk?
Yes! Whole milk will make it richer, while unsweetened almond or oat milk keeps it dairy-free.

How do I store and reheat leftovers?
Store in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of milk or broth to loosen the sauce.

Why isn’t my sauce thickening?
Make sure you’re cooking the flour long enough before adding liquid, and let the sauce simmer briefly after adding milk and broth.

Serving

Pair with a crisp green salad or roasted vegetables
Serve with garlic bread or a slice of crusty baguette

Suggestions
