Ingredients You’ll Need

This One Pot Cheesy Beef and Shells Recipe is made from simple, pantry-friendly ingredients that combine to deliver incredible flavor and texture. Each one plays a crucial role—from the beef that adds protein and heartiness, to the shell pasta which soaks up the sauce perfectly, and the cheese which brings that melty richness you crave.

• 1 pound lean ground beef: Use 90-93% lean for the best balance of flavor and fat.
• 1 large yellow onion, diced small: Provides sweetness and depth when sautéed.
• 3 garlic cloves, finely minced: Adds a punch of aromatic flavor.
• 2 tablespoons all-purpose flour: Helps thicken the sauce for creamy perfection.
• 2 cups reduced beef broth: Builds a rich base for the sauce.
• 1 8-ounce can tomato sauce: Gives the dish its tangy, savory body.
• 1 teaspoon Italian seasoning: Brings herbal warmth and complexity.
• 1 teaspoon paprika: Adds subtle smokiness and color.
• 1 teaspoon garlic powder: Enhances garlic flavor for extra punch.
• 1 teaspoon salt: Balances and elevates all flavors.
• 1 teaspoon freshly ground black pepper: Adds mild heat and earthiness.
• 8 ounces small pasta shells: Perfect size for capturing sauce—small elbow macaroni can be used but there’s a reason to stick with shells!
• ½ cup heavy cream: Makes the sauce decadently creamy.
• 2 ½ cups shredded cheddar cheese: The cheesy star of the dish that melts beautifully.
• Optional garnishes: Freshly grated Parmesan, fresh herbs like parsley or basil, or extra cheddar cheese for serving.

How to Make One Pot Cheesy Beef and Shells Recipe

Step 1: Brown the Ground Beef

Start by heating a large skillet over medium-high heat and adding your lean ground beef. Crumble it apart as it cooks so everything cooks evenly and gets beautifully browned. Once it’s cooked through, scoop it out with a slotted spoon and set it aside. Keep the flavorful drippings in the skillet—they’ll add so much to your onions and sauce.

Step 2: Sauté Onions and Garlic

In the same skillet with the beef drippings, add your diced onions and cook them until soft and translucent, about 4 minutes. Stir frequently so they cook evenly and don’t burn. Add the garlic last, cooking for just one minute to release that fragrant aroma without letting it brown too much.

Step 3: Make the Roux

Sprinkle the flour evenly over the sauteed onions and garlic, then stir constantly for about a minute. This step is crucial because you’re essentially creating a roux. This will thicken your sauce beautifully while avoiding any raw flour taste—don’t skip or rush this!

Step 4: Build the Sauce

Slowly pour in the beef broth while stirring continuously. Crank the heat to high and keep stirring until the sauce slightly thickens, about 1-2 minutes. Next, stir in tomato sauce, Italian seasoning, garlic powder, salt, pepper, and your dry pasta shells. Reduce the heat to medium-low, cover the skillet, and simmer for 10 minutes until the pasta is perfectly tender and most of the liquid is absorbed. Be patient—if the pasta needs more time, add a bit more broth and keep simmering.

Step 5: Add Cheese and Cream

Turn the heat back to medium-high and add your shredded cheddar cheese along with the heavy cream. Stir continuously as the cheese melts and the sauce becomes luxuriously creamy. This step transforms your dish into cheesy perfection.

Step 6: Combine Beef and Final Touches

Return the browned ground beef to the skillet, fold it in gently, and cook for another 1-2 minutes to warm everything through. If you like, sprinkle with extra cheese or fresh herbs right before serving for that irresistible finishing touch.

How to Serve One Pot Cheesy Beef and Shells Recipe

Garnishes

A simple sprinkle of freshly grated Parmesan or some chopped fresh herbs like parsley or basil adds a burst of color and fresh flavor that complements the rich, cheesy sauce beautifully. If you’re feeling extra cheesy, throw on a handful more shredded cheddar while it’s still hot.

Side Dishes

This dish is so hearty on its own, but a crisp green salad or steamed veggies can add a refreshing balance. Roasted broccoli, green beans, or a simple arugula salad with lemon vinaigrette pair perfectly and round out your meal without overpowering the main event.

Creative Ways to Present

Serve this dish straight from the skillet for a cozy, family-style vibe, or plate it elegantly with a sprig of fresh herbs and a drizzle of olive oil. You can even transfer leftovers into muffin tins for cheesy little handheld bites—ideal for parties or lunches on the go!

Make Ahead and Storage

Storing Leftovers

Leftover One Pot Cheesy Beef and Shells Recipe keeps beautifully when stored in an airtight container in the fridge for up to 5 days. The flavors continue to meld, making the next-day meal taste just as amazing.

Freezing

You can freeze leftovers for up to 3-4 months. Portion it into freezer-safe containers or bags, and thaw overnight in the fridge for best results. Keep in mind that some creamy sauces can change texture slightly after freezing, but it will still be delicious.

Reheating

Gently reheat leftovers in the microwave or on the stovetop over low heat to avoid overcooking the cream and cheese, which can sometimes cause separation. Stir frequently and add a little splash of broth or cream if the sauce looks too thick.

FAQs

Can I use other types of pasta instead of small shells?

While small shells are ideal because they hold the sauce well, small elbow macaroni can be substituted if needed. However, larger or more delicate pastas tend to lose texture or not capture the sauce as effectively, which changes the dish’s balance and mouthfeel.

Is it possible to make this recipe gluten-free?

Yes! Use gluten-free all-purpose flour or cornstarch for the roux, and swap the pasta shells for a gluten-free variety. Just keep an eye on cooking times as gluten-free pasta can cook faster.

Can I make this recipe vegetarian?

Absolutely. Swap the beef for plant-based crumbles or sautéed mushrooms for a meaty texture. Use vegetable broth instead of beef broth, and the flavor will still be rich and satisfying.

Why do I need to add flour in this recipe?

The flour creates a roux when combined with the fat and cooked onion mixture. It’s essential because it thickens the sauce, giving it that luscious, creamy consistency that clings to the pasta perfectly.

How can I make this dish spicier?

Add a pinch of red pepper flakes or a dash of hot sauce when you add the spices. You can also mix in some chopped jalapeños or use a smoked paprika with a bit of heat for added depth.
