Before you start

Before beginning, ensure all ingredients are measured and ready. Mince the garlic finely so it distributes evenly through the sauce. Shred the cheddar cheese if using a block, as it melts significantly better than pre-packaged shredded cheese.

Have a large colander ready for the pasta and ensure the skillet is clean and dry. Preparing these components in advance makes the cooking process fluid and stress-free, allowing for a seamless transition between boiling the pasta and preparing the sauce.

Ingredients at a glance (7)
  • 1 lb spaghetti
  • 1 lb ground beef
  • 4 cloves garlic, minced
  • 3 tbsp butter
  • 1 cup heavy cream
  • 2 cups cheddar cheese, shredded
  • parsley for serving

Instructions

Pasta preparation

  1. Prepare the pasta
    Bring a large pot of salted water to a boil. Add the spaghetti and cook according to the package instructions until al dente. Drain the pasta using a colander, reserving a small amount of the starchy pasta water for the sauce if needed.
    Look for The pasta should be tender but still firm to the bite.
    Tip Do not overcook the pasta, as it will continue to cook slightly when tossed with the hot sauce.

The pasta should be cooked until it is tender but still offers a slight resistance to the bite. It must be well-drained but not completely dry, as a little moisture helps the sauce bind to the strands. The water should be boiling rapidly when the spaghetti is added to ensure even cooking throughout the entire batch.

Sautéing the base

  1. Sauté the beef and garlic
    In a large skillet over medium-high heat, add the ground beef. Cook until browned and fully cooked through, reaching an internal temperature of at least 160°F (71°C). Stir in the minced garlic and butter, sautéing until fragrant and the garlic is softened.
    Look for The beef should be deeply browned and the garlic should smell aromatic without burning.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Drain any excess grease from the skillet before adding the cream if desired for a lighter sauce.

The beef should be thoroughly browned with no signs of pink remaining. The garlic should be golden and incredibly fragrant, having released its oils into the butter.

The mixture in the skillet should look and smell like a savory, aromatic foundation, with the fat from the beef mixing with the melted butter to create a rich base for the sauce.

Finishing the sauce

  1. Finish the sauce and assemble
    Pour the heavy cream into the skillet with the beef and bring to a gentle simmer. Gradually stir in the shredded cheddar cheese until the sauce is glossy and smooth. Toss the cooked spaghetti into the sauce, coating every strand thoroughly. Garnish with fresh parsley before serving.
    Look for The sauce should be thick, velvety, and cling to the spaghetti without being too oily.
    Tip Add a splash of reserved pasta water if the sauce becomes too thick while tossing.

The final sauce should be thick, glossy, and uniform in color. When the spaghetti is tossed in, it should be completely coated in a velvety layer of cheese and cream. The dish should smell rich and savory, with the parsley providing a fresh, bright finish that contrasts beautifully with the heavy, comforting sauce.

Common mistakes

A common mistake is rushing the browning of the beef, which prevents the development of essential flavor. Another error is adding the cheese to the cream while the heat is too high, which can cause the sauce to break or become grainy.

Maintain a gentle simmer when melting the cheese to ensure a smooth, velvety texture. Finally, failing to salt the pasta water sufficiently can lead to a bland dish, so ensure the water is seasoned well before the spaghetti goes in.

How to tell it’s done

The ground beef is fully cooked when it is no longer pink and reaches an internal temperature of at least 160°F (71°C). The sauce is done when it has achieved a glossy, thick consistency that coats the back of a spoon.

The cheese should be completely melted and incorporated into the cream without any separation. The pasta should be al dente, meaning it retains a slight chewiness, ensuring it holds its structure when tossed with the heavy sauce.

  • Ground meat: 160°F (71°C) in the thickest part
