Easy One-Pot Creamy Beef and Shells

There is nothing quite like a cozy skillet dinner to wrap up a chaotic day, and this Easy One-Pot Creamy Beef and Shells hits the absolute sweet spot. It gives you all those nostalgic, comforting hamburger-helper vibes but elevated with fresh ingredients and way more flavor.

The best part? You aren't boiling pasta in one pot and cooking meat in another. Everything—including the pasta shells—cooks right together in a single pan. That means fewer dishes, less mess, and a sauce that gets incredibly rich because the pasta releases its starches directly into the skillet.

Here is how to whip up this foolproof creamy beef and shells dinner.

Ingredients You'll Need

• 1 lb Lean ground beef

• 1 small Yellow onion, finely diced

• 2 cloves Garlic, minced

• 1 tbsp Italian seasoning

• Salt and black pepper to taste

• 2 tbsp Tomato paste

• 2 cups Marinara or tomato sauce

• 2 ½ cups Beef broth

• 8 oz Medium pasta shells (uncooked)

• ½ cup Heavy cream

• 1 cup Shredded cheddar or parmesan cheese (optional, but highly recommended)

Step-by-Step Instructions

1. Brown the Beef: Heat a large, deep skillet or cast-iron pan over medium-high heat. Add the ground beef and diced onion. Cook, breaking the meat apart with a wooden spoon, until the beef is fully browned and the onions are soft. Drain any excess grease.

2. Add Aromatics & Paste: Stir in the minced garlic, Italian seasoning, salt, and pepper. Cook for about 1 minute until fragrant. Add the tomato paste and stir it into the meat for another minute to deepen the flavor.

3. Simmer the Shells: Pour in the tomato sauce and beef broth, stirring to scrape up any yummy browned bits from the bottom of the pan. Stir in the uncooked pasta shells. Bring the liquid to a boil, then pop a lid on it, turn the heat down to low, and let it simmer for about 12 to 15 minutes (or until the pasta is tender). Give it a stir every few minutes so the shells don't stick!

4. Make it Creamy: Remove the skillet from the heat. Pour in the heavy cream and stir gently until the sauce transforms into a gorgeous, silky orange-tinted masterpiece.

5. Finishing Touch: If you are using cheese, fold it in now until completely melted and gooey. Let it sit for a couple of minutes to thicken up before serving.

Chef's Tips for Success

• Watch the Liquid: If your pasta is still a little too firm near the end but the liquid is mostly gone, just splash in an extra quarter-cup of broth or water.

• Make it Spicy: If you like a little kick to your one-pot creamy beef and shells, toss a generous pinch of red pepper flakes in with the garlic.

• Leftovers: This stores beautifully in the fridge for up to 3 days. When you reheat it, the pasta will have soaked up a lot of the moisture, so just add a splash of milk or broth before microwaving to bring that creamy texture right back to life.
