Ingredients

Units Scale

Pasta

  • 8 ounces medium pasta shells

Beef Mixture

  • 1 tablespoon olive oil
  • 1 pound ground beef
  • 1/2 medium sweet onion, diced
  • 2 cloves garlic, minced
  • 1 1/2 teaspoons Italian seasoning

Sauce

  • 2 tablespoons all-purpose flour
  • 2 cups beef stock
  • 1 (15-ounce) can tomato sauce
  • 3/4 cup heavy cream
  • Kosher salt and freshly ground black pepper, to taste
  • 6 ounces shredded extra-sharp cheddar cheese (about 1 1/2 cups)

Instructions

  1. Cook Pasta: In a large pot of boiling salted water, cook the medium pasta shells according to package instructions until al dente. Drain well and set aside.
  2. Brown the Beef: Heat olive oil in a large cast iron skillet over medium-high heat. Add the ground beef and cook, crumbling it with a spatula, until browned evenly, about 3-5 minutes. Drain excess fat and set the beef aside.
  3. Sauté Onions: In the same skillet, add diced sweet onion and cook while stirring frequently until translucent and softened, about 2-3 minutes.
  4. Add Aromatics and Seasoning: Stir in minced garlic and Italian seasoning and cook until fragrant, about 1 minute, ensuring the garlic does not brown.
  5. Create Roux: Whisk in the all-purpose flour and cook, stirring constantly, until it is lightly browned and integrated, about 1 minute. This will help thicken the sauce.
  6. Make the Sauce: Gradually whisk in the beef stock and tomato sauce, bringing the mixture to a boil. Then reduce heat and let it simmer, stirring occasionally until the sauce has reduced and thickened slightly, approximately 6-8 minutes.
  7. Combine and Heat Through: Stir in the cooked pasta, browned ground beef, and heavy cream into the skillet. Cook for 1-2 minutes until everything is heated through. Season with kosher salt and freshly ground black pepper to taste.
  8. Add Cheese: Sprinkle the shredded extra-sharp cheddar cheese over the mixture and stir until the cheese melts completely into the sauce, about 2 minutes.
  9. Serve: Serve the creamy beef and shells immediately while hot for the best texture and flavor.

Notes

  • For a spicier kick, add a pinch of crushed red pepper flakes along with the Italian seasoning.
  • Use freshly grated sharp cheddar cheese for better melting and flavor than pre-shredded varieties.
  • Make sure to drain excess fat from the beef to avoid a greasy sauce.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated gently on the stovetop or microwave.
  • For a lighter version, substitute heavy cream with half-and-half or a lower-fat cream alternative.
