One-Pot Creamy Beef and Shells

If you’re looking for an easy, comforting dinner that doesn’t require a pile of dishes, this One-Pot Creamy Beef and Shells is just what you need. Tender pasta shells, perfectly browned ground beef, and a rich tomato-cheddar sauce come together in one pot to create a delicious meal the entire family will enjoy.

The creamy sauce is made with beef broth, heavy cream, tomato paste, Italian seasoning, and sharp cheddar cheese. As the pasta cooks, it absorbs all those savory flavors, creating a thick, cheesy sauce reminiscent of homemade hamburger pasta with a touch of lasagna-inspired goodness.

It’s an excellent choice for busy weeknights when you want something hearty without spending hours in the kitchen. Serve it straight from the Dutch oven with garlic bread, warm dinner rolls, or a fresh green salad for a complete and satisfying meal.

Step-by-Step Instructions

Step 1: Cook the Onion and Garlic

Heat the olive oil in a large Dutch oven over medium heat. Add the diced onion and sauté for 3–4 minutes, stirring occasionally, until softened. Add the minced garlic and cook for another 30 seconds until fragrant.

Step 2: Brown the Ground Beef

Add the ground beef to the pot and season with salt and black pepper. Break it apart with a wooden spoon and cook for 5–7 minutes, until fully browned. Drain any excess grease if needed.

Step 3: Add the Pasta Shells

Spread the uncooked pasta shells evenly over the browned beef mixture, distributing them throughout the pot.

Step 4: Prepare the Creamy Cheese Sauce

In a separate bowl, whisk together the beef broth, heavy cream, tomato paste, and Italian seasoning until smooth. Mix in 1 cup of the shredded cheddar cheese and the red pepper flakes, if desired.

Step 5: Combine and Cook

Pour the prepared sauce over the beef and pasta. Gently press the shells down so they are mostly submerged in the liquid. Bring the mixture to a gentle simmer, then reduce the heat to low and cover with a lid.

Cook for 15–18 minutes, stirring once or twice during cooking, until the pasta is tender and the sauce has thickened.

Step 6: Adjust the Sauce

Check the consistency of the sauce. If it becomes too thick, stir in a little additional beef broth. If it seems too thin, remove the lid and let it simmer for another 2–3 minutes.

Step 7: Stir in the Remaining Cheese

Add the remaining ½ cup of shredded cheddar and stir until completely melted and incorporated into the sauce. Taste and adjust the salt, pepper, or other seasonings as needed.

Step 8: Rest and Serve

Remove the pot from the heat and let the dish rest for 3–5 minutes with the lid slightly open. Finish with grated Parmesan and fresh parsley, if desired. Serve hot while the sauce is creamy and the cheese is melted.

Serving Suggestions

• Garlic bread: Serve with toasted garlic bread to soak up the delicious cheesy sauce.
• Fresh green salad: Add a crisp salad with a light vinaigrette to balance the richness.
• Dinner rolls: Soft, warm rolls make a perfect side for this hearty pasta.
• Extra cheesy topping: Sprinkle additional cheddar or Parmesan over individual servings.
• Fresh finish: Add chopped parsley or a small squeeze of lemon juice for a brighter flavor.

This creamy beef and shells recipe is the perfect combination of convenience and comfort. With simple ingredients, one pot, and plenty of cheesy goodness, it’s a dinner you’ll want to make again and again!
