Method
- In a large skillet or Dutch oven over medium heat, cook the chopped bacon until crispy. Use a slotted spoon to transfer the bacon to a paper towel-lined plate, leaving about 1 tablespoon of bacon fat in the skillet. Simultaneously, cook pasta in a large pot of boiling salted water according to package directions until al dente.
- Add the diced onion to the skillet with the bacon fat and cook for 3-4 minutes until softened. Add the ground beef, season with salt and pepper, and cook, breaking it up with a spoon, until fully browned. Add the minced garlic and cook for one more minute until fragrant. Drain any excess grease.
- Melt the butter into the skillet with the beef. Sprinkle the flour over the beef, stir to combine, and cook for one minute to form a roux. Slowly pour in the broth while stirring constantly, then gradually pour in the heavy cream. Bring to a gentle simmer and cook for 2-3 minutes until it thickens slightly.
- Reduce the heat to low. Gradually stir in the shredded sharp cheddar and grated Parmesan cheese, a handful at a time, until the sauce is smooth. Do not let the sauce boil. Stir in the Worcestershire sauce and Dijon mustard. Taste and adjust seasoning with salt and pepper if needed.
- Add the cooked, drained pasta to the skillet with the sauce. Toss to coat everything evenly. Stir in three-quarters of the crispy bacon. Serve immediately, garnished with the remaining bacon and optional toppings like diced tomatoes, pickles, or green onions.
Notes
Chef's Tips: For the creamiest sauce, buy blocks of cheese and shred them yourself. Cook the pasta just to al dente as it will continue cooking in the sauce. Reserve a cup of starchy pasta water to thin the sauce if it becomes too thick.
Variations: Add 8 oz of sautéed cremini mushrooms with the beef for a 'Mushroom Swiss' flavor. For a spicy kick, sauté diced jalapeños with the onion.
Substitutions: Ground turkey or chicken can be used instead of beef. Any sturdy pasta like penne or rotini works well. Half-and-half can replace heavy cream for a lighter, though less rich, sauce.
