Ingredients

Serves 4–6 | Prep Time: 10 minutes | Cook Time: 25 minutes | Total Time: 35 minutes

Main Ingredients

  • 1 lb (450 g) ground beef (85% lean recommended)

  • 2 cups medium pasta shells (uncooked)

  • 1 small onion, finely chopped

  • 3 cloves garlic, minced

  • 1 tablespoon olive oil or butter

  • 1 teaspoon salt (adjust to taste)

  • ½ teaspoon black pepper

  • 1 teaspoon smoked paprika

  • 1 teaspoon Italian seasoning

  • 1 teaspoon chili powder (optional, for a mild kick)

  • 1 can (15 oz) tomato sauce

  • 1 can (14.5 oz) diced tomatoes (drained slightly)

  • 1 ½ cups beef broth or water

  • ½ cup heavy cream or milk

  • 2 cups shredded cheddar cheese (divided)

  • 1 cup shredded mozzarella cheese

  • Fresh parsley, chopped (for garnish)

Instructions

Step 1: Sauté the Aromatics

Heat olive oil or butter in a large deep skillet or sauté pan over medium heat. Add the finely chopped onion and sauté for 2–3 minutes until soft and translucent. Stir in the minced garlic and cook for 30 seconds, just until fragrant.

Step 2: Cook the Ground Beef

Add the ground beef to the pan. Break it apart using a spatula or wooden spoon and cook until browned — about 5–7 minutes. Drain any excess grease if necessary. Season with salt, black pepper, smoked paprika, Italian seasoning, and chili powder. Stir well to coat the beef in the seasonings.

Step 3: Add Liquids and Pasta

Pour in the tomato sauce, diced tomatoes, and beef broth. Stir everything together, then add the uncooked pasta shells directly into the sauce. Bring the mixture to a boil, then reduce heat to low. Cover and let simmer for about 12–15 minutes, stirring occasionally to prevent sticking, until the shells are tender and have absorbed much of the sauce.

Step 4: Add Cream and Cheese

Once the pasta is cooked, pour in the heavy cream or milk and stir to combine. Sprinkle in 1½ cups of shredded cheddar and ½ cup mozzarella. Stir until melted and smooth, creating a thick, cheesy sauce that clings to every shell.

Step 5: Melt and Serve

Top the dish with the remaining cheddar and mozzarella, then cover the pan again for 1–2 minutes to allow the cheese to melt completely. Garnish with freshly chopped parsley for color and freshness. Serve immediately while hot and bubbly.

Cooking Tips and Tricks

  1. Use the Right Pan:
    A deep, heavy-bottomed skillet or Dutch oven works best for this dish to ensure even cooking and prevent sticking.

  2. Don’t Overcook the Pasta:
    The shells continue to cook slightly after you remove them from the heat, so aim for just tender when you turn off the stove.

  3. Make It Creamier:
    For extra creaminess, swap the heavy cream for cream cheese or add a dollop of sour cream at the end.

  4. Add Vegetables:
    Sneak in extra nutrients by adding finely chopped spinach, bell peppers, or mushrooms while cooking the beef.

  5. Spice It Up:
    If you like heat, add a pinch of red pepper flakes or a drizzle of hot sauce when serving.

  6. Cheese Options:
    While cheddar and mozzarella create a classic flavor, you can experiment with Monterey Jack, Colby, or even pepper jack for a spicy twist.

Flavor Variations

  • Mexican-Style Beef & Shells:
    Add taco seasoning instead of Italian herbs, toss in some black beans, and top with jalapeños, salsa, and crushed tortilla chips.

  • Philly Cheesesteak Style:
    Replace tomato sauce with beef broth and cream cheese, then mix in sautéed bell peppers and onions for a creamy, savory variation.

  • Vegetarian Version:
    Swap the beef for plant-based ground meat or cooked lentils, and use vegetable broth instead of beef broth.

  • Bacon Lovers’ Upgrade:
    Stir in crumbled cooked bacon at the end for a smoky, salty punch of flavor.

Serving Suggestions

This cheesy beef and shells dish pairs beautifully with:

  • A crisp green salad tossed with a light vinaigrette.

  • Garlic bread or buttery breadsticks for scooping up the extra sauce.

  • A side of steamed broccoli or roasted veggies for a complete meal.

  • A refreshing iced tea or sparkling lemonade to balance the richness.

For a cozy family dinner, serve it right out of the skillet, letting everyone dig in. It’s also perfect for potlucks or meal prep — reheats beautifully without losing its creamy texture.

Storage and Reheating

To store: Allow leftovers to cool completely before transferring them to an airtight container. Store in the refrigerator for up to 4 days.

To reheat: Warm in a skillet over medium heat, adding a splash of milk or broth to restore creaminess. Alternatively, microwave in 1-minute intervals, stirring between each until heated through.

To freeze: Portion the dish into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Pro Tips for Perfect One-Pan Pasta

  1. Toast the Pasta (Optional):
    Before adding liquids, lightly toast the dry shells with the beef for 1–2 minutes. This enhances flavor and helps the pasta hold its shape.

  2. Simmer Slowly:
    Keeping the heat low ensures the sauce thickens gradually while the pasta absorbs maximum flavor.

  3. Finish with Fresh Herbs:
    Sprinkle parsley or basil just before serving to add freshness and contrast to the rich, cheesy sauce.

  4. Let It Rest:
    Give the dish 5 minutes before serving — this helps the sauce thicken and cling perfectly to the shells.
