Alfredo Spaghetti

There’s comfort food, and then there’s Alfredo Spaghetti—a silky, garlicky plate of pasta that hugs you from the inside. This version is simple, fast, and uses pantry-friendly ingredients to create a sauce that feels indulgent without fuss. It’s the kind of dinner you’ll crave on a cool night or anytime you want something cozy and a little luxurious.

Why this recipe works

What makes this rendition of Alfredo Spaghetti so satisfying is the balance of rich cream and sharp cheese tempered by a whisper of garlic and black pepper. The technique is straightforward: a little butter plus garlic for aromatics, heavy cream to form the sauce, Parmesan for body and salt, and a bit of reserved pasta water to bring everything together into a glossy, clingy coating for the spaghetti. The result is creamy without being gluey, and brightened with a sprinkle of fresh parsley.

Ingredients

• 10 ounces dry spaghetti
• 4 tablespoons unsalted butter
• 2 garlic cloves, minced
• 1 1/2 cups heavy cream
• Kosher salt, to taste
• 1/4 teaspoon black pepper
• 1/2 cup reserved pasta water (optional)
• 2/3 cup freshly grated Parmesan cheese
• Fresh parsley, chopped (for garnish)

Equipment you’ll need

• Large pot for boiling the spaghetti
• Colander
• Large skillet or sauté pan
• Tongs or pasta fork
• Measuring cups and spoons
• Grater for the Parmesan

Prep tips before you start

Measure out the spaghetti and other ingredients so everything is within reach. Grate the Parmesan fresh for the best texture and flavor—pre-grated cheese contains anti-caking agents that can affect melting. Mince the garlic finely so it releases its aroma quickly and evenly. Keep the reserved pasta water handy; its starchy quality helps the sauce cling to the noodles and creates a satin finish.

Step-by-step instructions

1. Bring a large pot of water to a rolling boil. Add a generous pinch of Kosher salt to the water—this seasons the spaghetti from the inside out.
2. Add 10 ounces dry spaghetti to the boiling water and cook according to the package instructions until al dente. Stir occasionally to prevent the noodles from sticking.
3. About 1 minute before the spaghetti is done, scoop out 1/2 cup of the cooking water and set it aside. This reserved pasta water is optional but recommended for finishing the sauce. Then drain the spaghetti in a colander.
4. While the pasta is cooking, place a large skillet over medium heat and add 4 tablespoons unsalted butter. Allow the butter to melt and foam without letting it brown.
5. Add 2 garlic cloves, minced, to the melted butter. Sauté the garlic for 30 to 60 seconds, stirring constantly, until it becomes fragrant. Take care not to let the garlic brown, as that will introduce a bitter note.
6. Pour 1 1/2 cups heavy cream into the skillet with the garlic and butter. Stir to combine and allow the mixture to come to a gentle simmer. Reduce the heat slightly so the cream simmers, but does not boil vigorously.
7. Season the cream with Kosher salt to taste and add 1/4 teaspoon black pepper. Stir and let the sauce simmer for 2 to 3 minutes, just until it thickens slightly and the flavors meld.
8. Reduce the heat to low and add the drained spaghetti directly into the skillet with the cream sauce. Use tongs or a pasta fork to toss the pasta so each strand is coated.
9. Sprinkle 2/3 cup freshly grated Parmesan cheese over the spaghetti. Toss continuously as the cheese melts into the warm cream, creating a smooth, velvety sauce.
10. If the sauce feels too thick or the pasta needs more gloss, add small splashes of the reserved pasta water (up to 1/2 cup) while tossing to achieve a silky consistency that clings to the spaghetti.
11. Taste and adjust the seasoning with additional Kosher salt and black pepper if needed. Remove the skillet from the heat once the sauce is smooth and the pasta is evenly coated.
12. Transfer the Alfredo spaghetti to serving plates or a large serving bowl. Garnish with a generous sprinkle of chopped fresh parsley for color and a bright herbal note.
13. Serve immediately while warm. Alfredo spaghetti is at its best right after it’s tossed, when the sauce is creamy and the noodles are perfectly coated.

Serving suggestions

This Alfredo Spaghetti is rich and comforting on its own, but it also plays well with additions. For a pop of green, toss in steamed broccoli florets just before serving. For added protein and texture, top plates with roasted chickpeas or seared tofu cubes. A light side salad with a lemony vinaigrette cuts through the richness beautifully. Finish with extra grated Parmesan at the table for those who want more cheesy depth.

Storage and reheating

Leftovers keep well in the refrigerator for up to 3 days when stored in an airtight container. The sauce will thicken as it cools; when reheating, add a splash of milk or reserved pasta water to loosen it and reheat gently on the stovetop over low heat, stirring constantly until the sauce regains a glossy texture. Microwaving works too—heat in short bursts and stir in a little liquid to restore creaminess.

Recipe notes and variations

• Cheese: Use freshly grated Parmesan for the best melting quality and flavor. Avoid pre-grated cheeses if you want a silky sauce.
• Garlic intensity: If you prefer a subtler garlic flavor, reduce the minced garlic to 1 clove. For a more pronounced garlic punch, add a small pinch of garlic powder while seasoning.
• Cream alternatives: This recipe calls for 1 1/2 cups heavy cream for a classic texture. If you need a slightly lighter version, you can experiment by replacing a portion of the cream with whole milk, but the sauce will be less rich and may require more stirring to remain cohesive.
• Pasta shape: Spaghetti is traditional here, but other long pastas like fettuccine or linguine work just as well. Shorter shapes will still be delicious, though the sauce coverage will differ slightly.
• Herbs and heat: Add chopped basil, chives, or a pinch of red pepper flakes for extra flavor dimensions.

Common troubleshooting

If your sauce becomes grainy or the cheese clumps, it’s usually because the temperature was too high when the cheese was added. Always keep heat low when you stir in the Parmesan. If the sauce is too thin, simmer it gently a little longer to reduce and thicken. If it’s too thick, whisk in reserved pasta water a tablespoon at a time until you reach the desired consistency.

Why reserve pasta water?

That small bit of starchy water is magic. It helps the cream and cheese emulsify, smoothing the sauce and allowing it to coat each strand of spaghetti without separating. It’s optional but highly recommended—add it gradually so the sauce stays silky.
