Ingredients
- Ground beef or turkey: This adds the rich base flavor and protein Choosing leaner ground meat keeps it lighter
- Worcestershire sauce: Boosts umami and balances the meat Choose a brand with minimal additives for the best taste
- Italian seasoning: Provides aromatic herbs for depth Look for a fresh blend or grind your own
- Garlic powder: Easy flavor without fuss Stick with fresh unless you need speed
- Smoked paprika: Smoky warmth that gives it a cozy taste Try Spanish paprika if possible
- Onions: A sweet foundation as they cook Look for firm onions with no soft spots
- Tomato paste: Adds deep savory notes Always use double concentrated if you can
- Shells pasta: Their shape catches the sauce perfectly Opt for bronze cut pasta for a superior bite
- Broth: Gives the pasta rich flavor and prevents dryness Use a low sodium version for control
- Fresh spinach: Bright color and nutrients Fresh leafy spinach wilts into the sauce beautifully
- Grated cheddar cheese: Melty and sharp for maximum creamy texture Shred your own for the best melt
- Plain Greek yogurt: The secret to a creamy finish without heaviness Always bring it to room temperature to prevent curdling
- Salt and pepper: Enhances everything Always season to your taste
Step-by-Step Instructions
- Brown the Beef:
- Break up the ground beef or turkey in a skillet over medium heat and let it cook for four to five minutes until there is no pink left This creates a savory base and lets rendered fat flavor the pan
- Season and Sauté:
- Drain off any excess fat from the pan Add Worcestershire sauce onions a teaspoon of Italian seasoning smoked paprika garlic powder salt and pepper Stir and cook for several minutes until the onions are soft and fragrant This builds deep umami and aromatic flavors
- Simmer the Pasta and Sauce:
- Add tomato paste shells pasta broth and another teaspoon of Italian seasoning Stir well and make sure the pasta is just submerged in liquid Use more broth or water as needed Adjust the heat to low then cover with a lid Let the pasta cook gently for ten to fifteen minutes Stir every four to five minutes so nothing sticks and the sauce stays silky
- Add Cheese and Spinach:
- When the pasta is soft and the liquid is mostly absorbed stir in grated cheddar cheese and fresh spinach Keep stirring over low heat just until the cheese melts and spinach wilts This gives you a creamy tangy and hearty base
- Finish with Greek Yogurt:
- Remove the skillet from the heat Let it cool uncovered for five to ten minutes Stir in room temperature Greek yogurt gently for creaminess Make sure not to add yogurt while the sauce is piping hot or it may curdle

Greek yogurt became my favorite swap here after experimenting with lighter cream sauces My kids could not even tell I left out the usual heavy cream and now Greek yogurt is my kitchen staple for so many creamy pastas
Storage Tips
Store leftovers in a tight container in the refrigerator for up to three days For best results reheat gently on the stovetop with a splash of extra broth to keep the sauce creamy The pasta can be frozen but the texture is best enjoyed fresh Spinach may release moisture after freezing so stir well
Ingredient Substitutions
Swap ground turkey or chicken for beef if you want a leaner flavor You can mix in kale instead of spinach or try mozzarella or Monterey Jack for the cheese If Greek yogurt is not available use full fat sour cream but do not use fat free as it may curdle
Serving Suggestions
Serve this dish with a crisp green salad and crusty bread to soak up the creamy sauce I also sometimes top with extra shredded cheddar or fresh basil for a flavor boost Leftovers fill lunchboxes or can be served as a protein rich snack after practice

Cultural Context
Beef and Shells is inspired by classic American skillet meals with a twist on nutrition The Greek yogurt and extra spinach reflect a modern take on weeknight cooking where high protein and added veggies are key American comfort food is evolving with these lighter faster twists that still feel nostalgic

How to Prepare
Heat a large cast iron skillet over medium heat. Add ground beef and cook for 4-5 minutes, breaking apart with a spatula, until completely browned and no longer pink.
Drain excess fat from the skillet. Add Worcestershire sauce, diced onion, 5 millilitres Italian seasoning, smoked paprika, garlic powder, salt, and black pepper. Stir well and cook until the onions are fragrant and softened.
Add tomato paste, shell pasta, broth, and remaining Italian seasoning. Stir to combine, ensuring pasta is mostly submerged. Add extra broth or water if needed.
Reduce the heat to low, cover skillet with a tight-fitting lid, and cook for 10-15 minutes. Stir every 4-5 minutes to prevent sticking and ensure even cooking, adding additional broth or water if the mixture appears dry.
Once pasta is al dente and most liquid is absorbed, remove the lid. Stir in grated cheddar cheese and fresh spinach. Cook until the cheese melts and spinach wilts.
Remove the skillet from heat and let cool for 5-10 minutes. Stir in Greek yogurt until fully combined for a creamy consistency. Serve immediately.
Extra Tips
- For optimal creaminess, use full-fat or 2% Greek yogurt and always add it after removing the pan from heat to prevent curdling.
- A tight-fitting lid ensures pasta retains moisture during simmering. Stirring periodically prevents scorching at the bottom of the pan.
- Worcestershire sauce adds complexity and enhances the flavour of ground beef. Substitute with soy sauce if desired.
- For a smoother sauce, a splash of olive oil or butter can be stirred in along with the yogurt.
- If preferred, cook pasta separately and fold into the beef mixture after simmering.
