One-Pot Creamy Comfort

This Crockpot Creamy Beef and Shells brings together savory ground beef, perfectly cooked pasta shells, and a luscious cheese-infused sauce, all melded together in a single slow-cooker. No stovetop juggling, no extra pans, and the result is a creamy, cheesy pasta that clings to every shell—ideal for busy weeknights.

The Secret to Ultra-Creamy Sauce

The key is to combine a roux-style flour-and-butter mixture with milk and broth before adding it to the crockpot. This thickens the sauce gently as it cooks, preventing grainy texture and ensuring every bite is silky. Adding the cheese at the end preserves its melt and flavor without becoming rubbery.

Ingredients for Crockpot Creamy Beef and Shells

• 1 lb ground beef
• 8 oz medium shell pasta (about 2 cups uncooked)
• 2 cups low-sodium beef broth
• 1 cup whole milk
• 1 cup shredded sharp cheddar cheese
• 2 cloves garlic, minced
• 1 tbsp all-purpose flour
• 1 tbsp butter
• 1 tsp onion powder
• ½ tsp black pepper
• ½ tsp salt

How to Make It: Crockpot Creamy Beef and Shells

1. Brown the ground beef in a skillet with the minced garlic, breaking it up until no longer pink; drain excess fat.
2. In a small saucepan melt butter, whisk in flour, and cook 1 minute to form a light roux; slowly whisk in milk and broth, simmering until slightly thickened.
3. Place the browned beef, uncooked shell pasta, onion powder, salt, and pepper into the crockpot.
4. Pour the thickened milk-broth mixture over the meat and pasta, stirring gently to combine.
5. Cover and cook on low for 3 hours, or on high for 1½ hours, until pasta is tender and sauce is creamy.
6. Stir in shredded cheddar cheese until melted and fully incorporated; let sit 5 minutes before serving.

Quick Tips for Success

Use a low-sodium broth so the dish doesn’t become overly salty, and choose medium shells that hold the sauce well. If you prefer a thicker sauce, add an extra tablespoon of flour to the roux. For a little heat, sprinkle a pinch of red-pepper flakes with the seasonings before cooking.

Serving Ideas

Serve the creamy beef and shells straight from the crockpot, topped with a extra sprinkle of cheddar and a drizzle of fresh chopped parsley if desired. Pair with a simple green salad or steamed broccoli for a balanced meal, and keep a crusty loaf of bread nearby to sop up any remaining sauce.

Common Questions

Can I use a different shape of pasta?

Yes, penne, rotini, or farfalle work well; just keep the pasta shape similar in size to shells.

What if I don’t have a slow cooker?

You can simmer the same ingredients in a covered Dutch oven on low heat for 45-60 minutes, stirring occasionally.

Can I make this ahead of time?

Absolutely—store the cooked dish in the refrigerator for up to 3 days and reheat gently on the stove or in the microwave.
