Ingredients

Makes 6 servings · serves 6

Main Ingredients

  • 1 lb macaroni pasta, raw
  • 1 tbsp Dijon mustard
  • 1/8 tsp ground nutmeg
  • 2 cups whole milk
  • 1 cup heavy cream
  • 4 cups shredded cheddar cheese
Contains: gluten, milk, mustard

Why this recipe works

The method of cooking pasta directly in the cooking liquid allows the starch released by the macaroni to thicken the sauce naturally. As the pasta hydrates, it absorbs the milk and cream, ensuring that every individual noodle is coated in a rich, flavorful layer that would be difficult to achieve using traditional boiling methods. This process creates a cohesive, velvety sauce that clings to the pasta, ensuring that the final dish is never watery, but instead perfectly rich and deeply satisfying for any hungry guest.

The slow cooker maintains a consistent, low temperature that prevents the dairy from curdling or separating, which is a common issue when cooking cheese sauces on the stovetop. This gentle heat ensures the cheese melts into the liquid slowly and evenly, creating a stable, emulsified sauce that remains creamy even as it begins to cool.

By avoiding the high, direct heat of a burner, you ensure the cheese remains smooth and glossy, providing a professional-quality texture that is consistent throughout the entire batch of macaroni.

Notes and substitutions

For the best results, use freshly shredded cheddar cheese rather than pre-shredded varieties. Pre-shredded cheese is often coated in cellulose to prevent clumping, which can interfere with the smoothness of the sauce and prevent it from melting as cleanly as freshly grated cheese. Taking the extra moment to grate your own cheese will significantly improve the final texture of the dish, resulting in a much smoother, more luxurious sauce that coats the noodles perfectly without any graininess or separation.

The choice of pasta is important; standard elbow macaroni is traditional, but other small shapes like shells or cavatappi also work well, as they are excellent at trapping the creamy sauce. Ensure the slow cooker is not overfilled, as the pasta will expand significantly during the cooking process and requires room to circulate.

Using a high-quality, firm pasta will help maintain the integrity of the dish, ensuring that the noodles remain tender but not mushy, providing a pleasant mouthfeel that complements the rich, velvety cheese sauce.

  • Heavy cream: Half-and-half for a slightly lighter sauce
  • Cheddar cheese: A blend of Gruyere and sharp cheddar for added depth
