Ingredients

2 cups low-sodium chicken stock, or vegetable broth
3 cloves garlic, minced
1 teaspoon kosher salt
½ teaspoon black pepper
8 ounces linguine or fettuccine noodles
2 tablespoons unsalted butter, divided
1 cup milk, plus ¼ cup if needed
1 pinch grated nutmeg
¼-½ cup freshly grated grated Parmesan Cheese

Equipment

Large pot for boiling pasta
Large skillet or sauté pan
Tongs or pasta fork
Measuring cups and spoons
Grater for Parmesan and nutmeg (optional)

Preheat & prep

Bring a large pot of water to a rolling boil for the pasta. While the water heats, mince the garlic, measure the stock/broth, milk, and Parmesan, and have your butter ready. Freshly grate the nutmeg and Parmesan for the best flavor.

Step-by-step directions

Salt the boiling water lightly if you like (remember your recipe already includes 1 teaspoon kosher salt). Add the 8 ounces of linguine or fettuccine noodles and cook according to package directions until al dente. Reserve about ½ cup of the pasta cooking water, then drain the pasta and set it aside.
While the pasta cooks, heat a large skillet over medium heat. Add 1 tablespoon of the 2 tablespoons unsalted butter and let it melt, swirling the pan so it coats the bottom.
Add the 3 cloves minced garlic to the melted butter and sauté for about 30–45 seconds, stirring constantly, until fragrant but not browned. Garlic cooks quickly—watch closely to prevent burning.
Pour in the 2 cups low-sodium chicken stock, or vegetable broth, and bring it to a gentle simmer. Let it reduce for 1–2 minutes to concentrate the flavor slightly.
Stir in 1 cup milk and the pinch of grated nutmeg. Continue to simmer for another 1–2 minutes, stirring so the mixture stays smooth and does not boil vigorously.
Add the remaining 1 tablespoon unsalted butter to the skillet and stir until it melts into the sauce.
Reduce the heat to low. Add ¼–½ cup freshly grated grated Parmesan Cheese to the sauce in small handfuls, stirring constantly to melt it evenly. Keep the sauce warm and smooth; if it seems too thick, stir in up to ¼ cup additional milk, a splash at a time, until you reach a silky, pourable consistency.
Season the sauce with 1 teaspoon kosher salt and ½ teaspoon black pepper, tasting and adjusting if needed. If you reserved pasta water, add a tablespoon at a time to the sauce to loosen it and help it cling to the noodles.
Add the drained pasta directly into the skillet with the sauce. Using tongs, toss the noodles gently but thoroughly so every strand is coated. Continue tossing for 30–60 seconds over low heat so the sauce thickens slightly and adheres to the pasta.
Serve immediately, dividing among bowls or plates. Sprinkle with an extra pinch of grated Parmesan for garnish if desired, and enjoy while hot.

Tips and variations

For a dairy-free version, substitute the milk with unsweetened fortified plant milk and use a dairy-free grated alternative in place of Parmesan. Keep the same proportions.
To add protein, top with pan-seared shrimp or sliced cooked chicken breasts. Make sure any additions are prepared and seasoned separately before tossing with the pasta.
If your sauce separates or becomes grainy, whisk in a splash of reserved pasta water over low heat to bring it back together.
Freshly grate the Parmesan and nutmeg for the best, clean flavor. Pre-grated cheeses can contain anti-caking agents that affect melting.
Add chopped fresh parsley, a squeeze of lemon, or a few red pepper flakes at the end for extra brightness and color.

Make-ahead and storage

This 15-Minute Fettuccine with Light Alfredo Sauce is best enjoyed immediately because the sauce thickens as it cools. If you must store leftovers, place cooled pasta in an airtight container and refrigerate for up to 2 days. Reheat gently in a skillet over low heat with a splash of milk or reserved pasta water to loosen the sauce.

Serving suggestions

Serve with a crisp green salad dressed simply with lemon and olive oil.
Pair with roasted vegetables—broccoli, asparagus, or cherry tomatoes work beautifully.
Offer crusty bread or garlic bread for sopping up any remaining sauce.

Final thoughts

This 15-Minute Fettuccine with Light Alfredo Sauce proves you don’t need heavy cream to get a luxurious, comforting pasta dinner on the table quickly. The combination of broth, milk, butter, and freshly grated Parmesan creates a silky sauce that clings to every strand of linguine or fettuccine. Keep the ingredients simple, watch the garlic closely, and finish with a final toss so the sauce and pasta marry perfectly. Simple, quick, and endlessly satisfying—this is the kind of recipe that becomes a regular in your weeknight rotation.

Enjoy your meal—and don’t be surprised if this dish becomes a go-to when you want something fast, creamy, and delicious.

A quick, lighter Alfredo made in one pan with broth, milk, butter, and Parmesan for a creamy weeknight pasta.

Prep Time2

Cook Time13

Total Time15

Servings: 4 servings

Ingredients

2 cups low-sodium chicken stock or vegetable broth
3 cloves garlic, minced
1 teaspoon kosher salt
1/2 teaspoon black pepper
8 ounces linguine or fettuccine noodles break in half to fit if needed
2 tablespoons unsalted butter, divided
1 cup milk plus up to 1/4 cup more if needed
1 pinch grated nutmeg
1/4-1/2 cup freshly grated Parmesan cheese

Instructions

In a large 12-inch skillet with a lid, combine 2 cups low-sodium chicken stock (or vegetable broth), minced garlic, kosher salt, and black pepper.
Add the linguine or fettuccine to the skillet, breaking the noodles in half to fit if needed, and place over medium-high heat.
Bring the liquid to a boil, stirring the pasta every 30 seconds so it doesn’t stick.
When the stock boils, reduce heat to medium-low and stir in 1 cup milk and 1 tablespoon butter.
Simmer on medium-low, stirring often, for 6–7 minutes or until the pasta is tender; if the liquid evaporates before the pasta is cooked, add up to an additional 1/4 cup milk 1 tablespoon at a time as needed.
Remove the skillet from the heat, add the remaining 1 tablespoon butter and let it melt while stirring to incorporate.
Stir in the grated Parmesan and a pinch of nutmeg, tossing until the pasta is evenly coated and the sauce is creamy; serve immediately.
