Ingredients for Alfredo Spaghetti
For the Alfredo Sauce:
- 2 tablespoons unsalted butter
- 3 garlic cloves, minced
- 1 cup heavy cream
- 1 cup freshly grated Parmesan cheese (not pre-shredded; it makes a huge difference!)
- 1/4 teaspoon ground nutmeg (optional, but adds depth)
- Salt and black pepper to taste
For the Spaghetti:
- 12 ounces spaghetti
- Salt for pasta water
Optional Add-ins:
- Grilled chicken, shrimp, or salmon
- Steamed broccoli, peas, or spinach
- Red pepper flakes for a spicy kick
How to Make Alfredo Spaghetti?
Step 1: Cook the Spaghetti
- Fill a large pot with water, add a generous amount of salt, and bring it to a boil.
- Add the spaghetti and cook according to the package instructions until al dente.
- Reserve 1/2 cup of pasta water, then drain the spaghetti.

Step 2: Make the Alfredo Sauce
- In a large skillet or saucepan, melt the butter over medium heat.
- Add the minced garlic and sauté until fragrant, about 1 minute.
- Pour in the heavy cream and stir. Bring it to a gentle simmer, then lower the heat.
- Gradually whisk in the Parmesan cheese until fully melted and smooth.
- Season with nutmeg (if using), salt, and pepper. Adjust to taste.

Step 3: Combine and Serve
- Add the cooked spaghetti to the skillet with the sauce. Toss to coat, adding reserved pasta water as needed to reach your desired consistency.
- Transfer to serving plates and garnish with extra Parmesan, chopped parsley, or red pepper flakes.

Tips for Success
- Use freshly grated Parmesan: Pre-grated cheese doesn’t melt as well and can lead to a grainy sauce.
- Don’t overheat the sauce: Keep the heat low to prevent the cream from curdling.
- Reserve pasta water: This starchy water helps bind the sauce to the pasta for a silky finish.
- Serve immediately: Alfredo sauce is best enjoyed fresh and creamy.
Variations
- Protein-packed: Add grilled chicken, seared shrimp, or crispy bacon.
- Vegetarian twist: Incorporate sautéed mushrooms, roasted bell peppers, or zucchini.
- Gluten-free option: Use gluten-free spaghetti or zucchini noodles.
- Low-calorie version: Swap heavy cream for half-and-half or evaporated milk, and use whole wheat pasta.
