One Pot Creamy Beef and Shells

Featured in: One-Pot Comfort Bowls

This comforting one-pot dinner combines tender ground beef with medium pasta shells in a velvety tomato-cream sauce. The magic happens as the pasta cooks directly in the beef broth and tomatoes, absorbing all those savory flavors while the sauce naturally thickens. A blend of heavy cream, milk, and two cheeses creates the luscious texture that coats every shell. Ready in under 40 minutes with just one pan to clean, this hearty dish is perfect for busy weeknights when you want something satisfying without the fuss. Garnish with fresh parsley for a bright finish.

Rain was tapping against my kitchen window last Tuesday when I realized I had zero energy for a multi-pot dinner situation. That rainy evening exhaustion led me to throw everything into one Dutch oven and hope for the best. The way my husband's eyes lit up when he walked through the door told me this accidental creation was something special. Sometimes the best meals come from pure laziness mixed with desperation.

My sister called me mid-cooking that evening, complaining about her own dinner disaster. I told her about this bubbling pot on my stove and how good my kitchen smelled. She came over twenty minutes later with a bottle of wine and an empty stomach. We ended up eating straight from the Dutch oven standing at the counter because neither of us could wait to actually set the table.

Ingredients

  • 1 lb ground beef: The 80/20 ratio gives you the perfect amount of fat for flavor without being too greasy
  • 1 small yellow onion: Finely chopped so it almost disappears into the sauce
  • 2 cloves garlic: Minced fresh beats powdered every single time
  • 8 oz medium pasta shells: The curves catch all that creamy sauce in tiny pockets
  • 2 cups beef broth: Use low sodium so you can control the salt level
  • 1 can crushed tomatoes: Creates that rustic texture that feels homemade
  • 1/2 cup heavy cream: This is what transforms tomato soup into restaurant-quality sauce
  • 1/2 cup whole milk: Balances the richness so it is not overwhelming
  • 1 cup shredded cheddar cheese: Sharp adds the best depth of flavor
  • 1/2 cup grated Parmesan cheese: Salty and nutty and absolutely essential
  • 1 tsp Italian seasoning: Your shortcut to herb heaven without measuring seven different things
  • 1/2 tsp paprika: Adds a subtle smoky note that people cannot quite put their finger on
  • 1/2 tsp salt: Adjust this at the end since broths vary in sodium
  • 1/4 tsp black pepper: Freshly ground makes a huge difference here
  • 1/4 tsp crushed red pepper flakes: Optional but that tiny kick makes everything better
  • 2 tbsp chopped fresh parsley: Makes it look like you tried harder than you actually did

Brown the beef:
Cook ground beef in your largest deep skillet over medium-high heat breaking it apart with a wooden spoon until it is no longer pink. Drain some fat if there is an excessive amount but leave a little for flavor.
Build the base:
Toss in chopped onion and cook for about 3 minutes until it is soft and translucent. Add minced garlic and stir constantly for 30 seconds until your kitchen smells amazing.
Combine everything:
Dump in uncooked pasta shells beef broth crushed tomatoes and all those seasonings. Stir well to make sure every piece of pasta is tucked under the liquid.
Simmer away:
Bring it to a gentle bubble then turn down to medium-low and cover. Let it cook for 12-14 minutes stirring occasionally so nothing sticks to the bottom.
Add the creamy magic:
Pour in heavy cream and whole milk and let it simmer uncovered for 2-3 more minutes. Watch how the sauce suddenly transforms into something velvety.
Cheese time:
Stir in cheddar and Parmesan until completely melted and the sauce coats the back of your spoon. Taste and add more salt or pepper if needed.
Finish and serve:
Take it off the heat and sprinkle with fresh parsley and red pepper flakes if you like a little heat. Serve immediately while the cheese is still gorgeously stretchy.

This recipe became my go-to for new parents and friends who just need someone to handle dinner for once. My neighbor texted me at midnight after I dropped off a container saying she ate it cold standing in her kitchen because she could not even wait to heat it up. That is when I knew this was not just a recipe but a genuine act of love.

Making It Lighter

Swap the heavy cream for half-and-half or even whole milk if you are watching calories but still want that velvety texture. Ground turkey works beautifully too though you might want to add a splash of olive oil since it is so lean. I have made this with ground chicken and it was still gone in twenty minutes flat.

Getting Creative

Sometimes I throw in a handful of baby spinach during the last two minutes of cooking just to feel better about serving pasta for dinner. Frozen peas work too and add these tiny pops of sweetness throughout. My kids actually started eating their vegetables better when I hid them in this pasta.

Perfect Pairings

A simple green salad with vinaigrette cuts through all that richness beautifully. Crusty bread for sauce mopping is non-negotiable in my house. If you are feeling fancy a glass of red wine turns Tuesday dinner into a legitimate experience.

  • The sauce thickens up in the fridge so add a splash of milk when reheating
  • Ground sausage mixed with the beef creates incredible depth
  • Use whatever pasta shape you have but shells really are superior here

There is something deeply satisfying about a meal that comes together so effortlessly yet tastes like it simmered all day. That rainy Tuesday discovery has saved me countless weeknights since.

Recipe Questions & Answers

Can I use different pasta shapes?

Yes, medium shells work perfectly because they hold the creamy sauce well, but you can substitute with rotini, penne, or rigatoni. Just adjust cooking time as needed since different shapes may cook at slightly different rates.

How do I store leftovers?

Store cooled leftovers in an airtight container in the refrigerator for up to 3-4 days. The sauce will thicken further as it sits—add a splash of milk or broth when reheating to bring back the creamy consistency.

Can I make this ahead of time?

This dish is best enjoyed fresh, but you can prep ingredients ahead. Chop the vegetables and shred the cheese up to a day in advance. The pasta continues to absorb liquid, so if making ahead, undercook slightly and add extra liquid when reheating.

What can I substitute for ground beef?

Ground turkey, chicken, or Italian sausage work well as alternatives. For a vegetarian version, use plant-based crumbles or add extra vegetables like mushrooms, bell peppers, and zucchini for bulk and texture.

Why is my sauce too thick?

If the sauce becomes too thick, simply add more beef broth, milk, or even a bit of water until you reach your desired consistency. Remember the pasta continues absorbing liquid even after cooking, so it's normal for the sauce to thicken as it stands.

Can I freeze this dish?

You can freeze it for up to 2-3 months, though the pasta texture may soften slightly. Cool completely, transfer to a freezer-safe container, and thaw overnight in the refrigerator before reheating with a splash of milk to restore creaminess.
