This creamy beef and shells pasta has become my weeknight dinner hero when I need something quick that everyone will happily devour. The combination of tender pasta shells, savory beef, and rich cheese sauce creates a homemade version of that boxed comfort food we all secretly love, but with real ingredients and so much more flavor.
I first created this recipe during a particularly busy week when I needed something quick but still homemade. My family now requests it almost weekly, and I love how I can sneak extra veggies in when nobody is looking.
Ingredients
- Ground beef: preferably 80/20 or 85/15 for the perfect balance of flavor and less grease
- Medium pasta shells: which capture the creamy sauce perfectly in their little pockets
- Sweet onion: for a mild aromatic base that even picky eaters won't complain about
- Fresh garlic cloves: which provide irreplaceable depth of flavor
- Italian seasoning blend: saves time while adding balanced herbs
- Smoked paprika: gives a subtle smoky note without being overpowering
- All-purpose flour: creates the base for our velvety sauce
- Beef stock: enhances the meaty flavor throughout the dish
- Marinara sauce: adds tomato richness and saves time
- Heavy cream: provides luxurious texture without being too heavy
- Sour cream: adds a pleasant tanginess that balances the richness
- Freshly grated cheddar cheese: melts beautifully and adds sharp flavor
Step-by-Step Instructions
- Cook the Pasta:
- Bring a large pot of water to a rolling boil and add a generous amount of salt. Cook the pasta shells until just al dente according to package directions usually about 8 minutes. The pasta will continue cooking slightly when added to the sauce so keeping it slightly firm now prevents mushiness later. Drain well but do not rinse as the starch helps the sauce cling better.
- Brown the Beef:
- Heat olive oil in a large deep skillet over medium high heat until shimmering. Add the ground beef breaking it into small pieces with a wooden spoon. Allow it to cook undisturbed for about a minute to develop some browning before stirring. Continue cooking until no pink remains about 3 to 5 minutes total. Drain off excess fat leaving just a tablespoon for flavor then transfer the meat to a plate.
- Sauté the Aromatics:
- In the same skillet add the diced onion to the remaining fat and cook for about 2 minutes until beginning to soften and become translucent. Add the minced garlic and cook just until fragrant about 30 to 60 seconds being careful not to burn it which would add bitterness.
- Create the Roux:
- Sprinkle the flour over the onion and garlic mixture whisking constantly for about one minute. The mixture will look paste like and slightly golden. This quick cooking prevents raw flour taste while creating the base for a thick sauce.
- Build the Sauce:
- Slowly pour in the beef stock while whisking continuously to prevent lumps from forming. Add the marinara sauce and all the dried herbs Italian seasoning parsley oregano and smoked paprika. Stir to combine thoroughly making sure no flour lumps remain.
- Simmer and Reduce:
- Bring the sauce to a gentle boil then immediately reduce to a simmer. Allow it to cook uncovered for 6 to 8 minutes stirring occasionally. The sauce will thicken slightly and the flavors will intensify as it reduces. You should see it coat the back of a spoon when ready.
- Combine Components:
- Add the cooked pasta shells to the sauce along with the reserved browned beef. Stir gently to coat everything evenly making sure the shells get filled with sauce. Allow this to cook together for about a minute so the pasta can absorb some flavor.
- Enrich with Dairy:
- Pour in the heavy cream and stir until fully incorporated and heated through about 1 to 2 minutes. The sauce will take on a beautiful orange hue. Taste now and season with salt and pepper as needed remembering that the cheese will add saltiness too.
- Finish with Creaminess:
- Remove the skillet from heat and stir in the sour cream until completely blended. This adds tanginess and extra creaminess without the risk of curdling. Immediately add the grated cheddar cheese and fold gently until melted and incorporated throughout the dish.
- Serve Immediately:
- Portion into bowls while hot and fresh. The sauce will continue to thicken as it stands so enjoy at its creamiest right away. A sprinkle of fresh parsley adds a nice color contrast if desired.

You Must Know
This dish reheats beautifully making it perfect for meal prep. The small pasta shells act like little sauce catchers for maximum flavor in each bite. Leftovers actually taste even better the next day as flavors meld overnight.
Perfect Pasta Selection
While medium shells are ideal for this recipe due to their sauce capturing ability you can substitute other short pastas with good results. Elbow macaroni cavatappi or even bow ties work well. The key is choosing a shape with nooks and crannies that can hold the creamy sauce. For a slightly healthier version whole wheat pasta adds fiber though the texture will be slightly different. Avoid long strand pasta like spaghetti or angel hair which does not hold the chunky beef sauce as effectively.

Making It Your Own
This beef and shells recipe welcomes customization based on what you have on hand. For extra nutrition add finely chopped bell peppers zucchini or carrots with the onions. Spinach stirred in at the end just until wilted adds color and vitamins. For a spicier version include red pepper flakes or a dash of hot sauce. Italian sausage can replace some or all of the ground beef for an even more flavorful twist. The recipe works beautifully with ground turkey or chicken too adjust seasoning as these leaner meats need more help in the flavor department.
Serving Suggestions
This hearty dish shines on its own but pairs wonderfully with simple sides. A crisp green salad with a bright vinaigrette offers refreshing contrast to the rich pasta. Garlic bread or crusty Italian bread makes the perfect vehicle for sopping up every last bit of the delicious sauce. For a complete meal that still feels light roasted broccoli or asparagus alongside provides a veggie component that balances the creamy richness. In summer months grilled vegetables make an excellent accompaniment. Consider serving in bread bowls for an extra special presentation that kids and adults alike will love.
Troubleshooting Tips
If your sauce seems too thick simply add a splash more beef broth or cream until you reach your desired consistency. Conversely if the sauce is too thin let it simmer a few minutes longer or add a tablespoon more of grated cheese. Should your sauce break or look curdled remove from heat immediately and whisk in a tablespoon of cold cream. The most common mistake is overcooking the pasta resulting in a mushy texture so be vigilant about cooking it just to al dente.
