Ingredients and Preparation

Pasta Shells
These little pasta pockets are perfect for catching every drop of the creamy beef sauce. Choose medium shells for the best balance of bite and sauce coverage.

Ground Beef
A classic base, ground beef provides richness and protein. Opt for lean ground beef to reduce excess grease while keeping all the flavor.

Sweet Onion
Adds subtle sweetness and depth that enhances the savoriness of the beef without overpowering it.

Garlic
Brings aromatic warmth and classic Italian flavor. Fresh minced garlic is best, but garlic powder works in a pinch.

Italian Seasoning
A pre-mixed blend of herbs like oregano, basil, and thyme that ties the whole dish together. You can adjust the blend to match your taste preferences.

Flour
Used to create a roux, which thickens the sauce without needing cornstarch or other thickeners.

Beef Stock
Adds moisture and a deep, savory note that complements the meat beautifully. Chicken or vegetable broth can work in a pinch.

Marinara Sauce
Provides a tangy tomato base. Jarred sauce is fine, but you can use crushed tomatoes or tomato puree if preferred.

Heavy Cream and Sour Cream
These are the secret weapons for velvety texture and a subtle tang. Greek yogurt can replace sour cream for a lighter option.

Cheddar Cheese
Freshly shredded cheese melts best and gives that luscious, gooey finish. You could swap it for Monterey Jack or mozzarella for a milder touch.

Step-by-Step Instructions

Step 1 Start by cooking your pasta shells in salted boiling water until just al dente—this means they should still have a slight bite since they’ll continue cooking in the sauce.

Step 2 In a large skillet or pot over medium heat, cook your ground beef until browned, breaking it apart with a spatula as it cooks. Drain excess grease if needed.

Step 3 Add finely chopped onion and garlic to the beef and sauté until the onion becomes translucent and the garlic is fragrant, about 2–3 minutes.

Step 4 Sprinkle in flour and stir continuously for about one minute to form a light roux, which will help thicken the sauce.

Step 5 Slowly pour in the beef stock while stirring to avoid lumps, then add marinara sauce. Let it come to a gentle simmer.

Step 6 Season the sauce with Italian herbs, salt, and pepper to taste, then add the cooked pasta back into the pot and stir to combine.

Step 7 Reduce heat to low, then stir in the heavy cream and sour cream until the sauce becomes creamy and smooth.

Step 8 Finally, fold in the shredded cheddar cheese and stir until fully melted and incorporated, coating every pasta shell in deliciously cheesy sauce.

Beginner Tips and Notes

Avoid Overcooking Pasta: Since the pasta will cook more once mixed with the sauce, undercook it slightly during the initial boil.

Sauce Too Thick? Add a splash of milk or extra broth until it reaches your desired consistency.

Cheese Clumping? Make sure your pot is on low heat when adding cheese—too much heat can cause it to separate.

Short on Time? You can prep onions and garlic in advance or buy pre-chopped versions from the grocery store.

No Pasta Shells? Try elbow macaroni, rotini, or penne instead—they all hold sauce well.

Serving Suggestions

Serve your creamy beef and shells with a simple green salad dressed with lemon vinaigrette for balance. Garlic bread or roasted vegetables also pair beautifully.

Leftover Tips: Store in an airtight container in the fridge for up to four days. Add a splash of milk or water before reheating on the stove or in the microwave to bring back its original creamy texture. It’s also freezer-friendly—portion it out and freeze for up to two months.
