Bring a large pot of salted water to a rolling boil—this will take 8-10 minutes. While the water heats, mince your garlic cloves fresh (this makes a real difference in flavor), grate your Parmesan cheese if not already grated, and have your heavy cream measured and ready. Once boiling, add the pasta and cook according to package directions until al dente, then drain and set aside, reserving a cup of pasta water for later adjustments.

Heat olive oil in a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a wooden spoon, until it's deeply browned and cooked through (about 5-7 minutes). This browning step builds flavor through the Maillard reaction—don't rush it. Once fully cooked, carefully drain off excess fat by tilting the pan and spooning it out, leaving just a light coating in the bottom.

Add the minced garlic to the browned beef and cook for 1-2 minutes, stirring constantly. You'll know it's ready when you smell that wonderful garlic fragrance—this blooms the garlic flavor into the oil. Don't let it brown or burn, as that will make it bitter.

Pour the heavy cream into the skillet and reduce heat to medium-low, simmering gently for 2-3 minutes to warm through. Slowly add the grated Parmesan cheese in batches, stirring constantly until each addition melts completely before adding more. I like to add the nutmeg at this point—just a pinch adds a subtle sophistication that makes people wonder what the secret ingredient is. Continue stirring until the sauce is smooth and creamy, then season with salt and black pepper to taste.

Add the cooked pasta from Step 1 to the Alfredo sauce and toss gently to coat, cooking together for 1-2 minutes so the flavors meld. If the sauce seems too thick, add a splash of the reserved pasta water to reach your desired consistency—the starch in the pasta water helps the sauce cling beautifully to the noodles.

Divide the pasta into bowls or plates and garnish generously with fresh parsley. Serve immediately while hot and creamy.
