Creamy One-Pot Beef and Shells

This creamy one-pot beef and shells is the kind of comforting dinner that feels almost too easy for how satisfying it is. Everything happens right in a single Dutch oven: ground beef browns in the pot, uncooked pasta shells go in next, and then one creamy, savory liquid gets poured over the top. As everything simmers together, the pasta absorbs the rich sauce while the beef and cheese create a hearty dish that tastes like a cozy cross between skillet lasagna and homemade hamburger helper.

It’s the perfect meal for busy evenings when you want something homemade without spending hours in the kitchen. The sauce is made from simple ingredients—beef broth, heavy cream, tomato paste, Italian seasoning, and melted cheddar cheese—creating a creamy, tomato-kissed sauce that clings to every pasta shell.

Serve this dish straight from the Dutch oven with a crisp green salad tossed in a light vinaigrette to balance the richness. Garlic bread or warm dinner rolls are perfect for scooping up the extra sauce. A sprinkle of fresh parsley or grated Parmesan adds a final touch of brightness before serving.

Recipe Details

  • Recipe: Creamy One-Pot Beef and Shells
  • Servings: 6 servings
  • Prep Time: 10 minutes
  • Cook Time: 20 minutes
  • Total Time: 30 minutes

Ingredients

  • 1 tablespoon olive oil
  • 1 medium yellow onion, finely diced
  • 2 cloves garlic, minced
  • 1½ pounds ground beef (80–90% lean)
  • 1 teaspoon kosher salt
  • ½ teaspoon black pepper
  • 12 ounces uncooked medium pasta shells
  • 2 cups beef broth
  • 1½ cups heavy cream
  • 3 tablespoons tomato paste
  • 2 teaspoons Italian seasoning
  • 1½ cups shredded sharp cheddar cheese, divided
  • ¼ teaspoon crushed red pepper flakes (optional)
  • 2 tablespoons grated Parmesan cheese (optional)
  • 2 tablespoons chopped fresh parsley (optional)

Instructions

  1. Sauté the onion.
    Heat a large Dutch oven over medium heat and add the olive oil. Add the diced onion and cook for about 3–4 minutes until softened and translucent.
  2. Add the garlic.
    Stir in the minced garlic and cook for about 30 seconds until fragrant.
  3. Brown the beef.
    Add the ground beef, salt, and black pepper. Cook for 5–7 minutes, breaking the meat apart with a spoon until fully browned. Drain excess grease if needed.
  4. Add the pasta shells.
    Turn off the heat briefly and scatter the uncooked pasta shells evenly over the beef. Avoid stirring at this point.
  5. Prepare the creamy sauce.
    In a bowl or measuring cup, whisk together the beef broth, heavy cream, tomato paste, and Italian seasoning until smooth. Stir in 1 cup of the shredded cheddar cheese and the red pepper flakes if using.
  6. Pour the sauce.
    Return the pot to medium heat and pour the creamy mixture over the pasta and beef. Press the pasta gently into the liquid so it cooks evenly.
  7. Simmer.
    Bring the mixture to a gentle simmer, then reduce the heat to low. Cover and cook for 15–18 minutes, stirring once or twice, until the pasta is tender and the sauce thickens.
  8. Adjust the consistency.
    If the sauce is too thick, add a splash of broth or water. If too thin, simmer uncovered for a few minutes until slightly reduced.
  9. Add the cheese.
    Remove from heat and stir in the remaining ½ cup cheddar cheese until melted and creamy.
  10. Rest and serve.
    Let the dish rest for about 3–5 minutes. Garnish with Parmesan cheese and fresh parsley if desired, then serve warm.

Tips for the Best Results

  • Use medium pasta shells so they hold the creamy sauce.
  • Stir once or twice during cooking to prevent sticking.
  • Shred cheese fresh for smoother melting.
  • Let the pasta rest a few minutes so the sauce thickens.

Variations & Add-Ins

  • Add frozen peas or mixed vegetables during the last 5 minutes.
  • Sauté diced bell peppers with the onions for extra flavor.
  • Swap cheddar for mozzarella or Monterey Jack.
  • Use half-and-half instead of some of the heavy cream for a lighter version.

Serving Suggestions

  • Serve with garlic bread or crusty bread.
  • Add a crisp green salad with vinaigrette.
  • Pair with sparkling water, iced tea, or a light white wine.
