Ingredients

(Serves 4–6)

For the Beef:

  • 1 lb ground beef (or chopped sirloin pieces, as shown in the picture)

  • 1 tablespoon olive oil

  • 1 teaspoon garlic powder

  • 1 teaspoon onion powder

  • 1 teaspoon Italian seasoning

  • ½ teaspoon crushed red pepper (optional)

  • Salt and black pepper to taste

For the Pasta & Sauce:

  • 12 oz medium pasta shells

  • 1 small onion, finely diced

  • 4 cloves garlic, minced

  • 2 tablespoons butter

  • 2 tablespoons all-purpose flour

  • 2 cups beef broth

  • 1 ½ cups heavy cream

  • 4 oz cream cheese, softened

  • 1 cup shredded mozzarella cheese

  • ½ cup grated Parmesan cheese

  • 1 teaspoon paprika

  • 1 teaspoon dried basil

  • Salt and pepper, to taste

  • Fresh parsley, chopped (for garnish)

Step-by-Step Instructions

1. Cook the Pasta

Bring a large pot of salted water to a boil. Add the pasta shells and cook until al dente.
Drain, drizzle lightly with olive oil to prevent sticking, and set aside.

The shells are perfect for this dish — their shape captures every ounce of the cheesy cream sauce.

2. Sear the Beef

Heat the olive oil in a large deep skillet or sauté pan over medium-high heat.
Add the beef, breaking it apart or searing the steak bites (as in the photo). Season with:

  • garlic powder

  • onion powder

  • Italian seasoning

  • salt & pepper

  • red pepper flakes (optional)

Cook until the meat is browned, aromatic, and slightly crispy on the edges — about 5–7 minutes.
Transfer to a bowl and set aside, leaving the drippings in the skillet.

Those browned bits add HUGE flavor to the next step.

3. Sauté the Aromatics

In the same skillet, melt 2 tablespoons of butter.
Add the diced onion and cook for 3–4 minutes until soft and golden.
Stir in the minced garlic and cook another 30 seconds.

This base builds the backbone of your creamy sauce.

4. Make Your Roux

Sprinkle the flour over the onions and garlic, stirring continuously for 1 minute.
This cooks out the raw flour taste while preparing the sauce to thicken perfectly.

5. Add Broth and Cream

Slowly whisk in:

  • beef broth

  • heavy cream

Stir continuously until smooth, creamy, and beginning to thicken.
Reduce the heat to medium-low and let the sauce simmer 3–5 minutes.

6. Melt in the Cheeses

Add:

  • softened cream cheese

  • shredded mozzarella

  • Parmesan

Stir slowly until everything melts into a luxurious, silky sauce.
Season the sauce with:

  • paprika

  • dried basil

  • salt & pepper

This creates the rich, savory flavor that makes every bite irresistible.

7. Combine Everything

Return the cooked beef to the skillet.
Add the cooked pasta shells.

Toss gently until every shell is coated in the creamy cheese sauce and the beef is fully incorporated.

Let everything simmer together for 2–3 minutes so the flavors blend and the sauce thickens beautifully.

8. Garnish and Serve

Sprinkle chopped parsley and a bit of extra Parmesan on top.
Serve hot and enjoy every comforting bite!

⭐ Recipe Tips & Tricks

✔ Don’t skip browning the beef

This adds deep flavor and creates those delicious crispy bits.

✔ Use freshly shredded cheese

Fresh cheese melts into the sauce smoothly — pre-shredded varieties contain starch that can make sauce grainy.

✔ Let the sauce thicken naturally

Keep it on low heat and stir — it turns velvety and perfect.

✔ Want more heat?

Add extra red pepper flakes or a dash of Cajun seasoning.

✔ Prefer a deeper beef flavor?

Use half beef broth and half Worcestershire sauce for richness.

Variations

🔥 Spicy Version

Add a teaspoon of Cajun seasoning and more crushed red pepper.

🍄 Mushroom Beef Shells

Sauté sliced mushrooms with the onions for an earthy, hearty twist.

🌶 Creamy Chipotle Beef & Shells

Add 1–2 teaspoons chipotle peppers in adobo to the sauce.

🧀 Four-Cheese Upgrade

Add smoked gouda or sharp white cheddar for richness.

🥦 Add Veggies

Stir in spinach, peas, broccoli, or bell peppers for extra color and nutrition.

What to Serve With Creamy Beef & Shells

  • Garlic bread

  • Caesar salad

  • Roasted asparagus

  • Steamed broccoli

  • A crisp green side salad

The dish is rich and comforting, so pairing it with something light and fresh balances it beautifully.

Storage & Reheating

Fridge:

Store in an airtight container for up to 4 days.

Freezer:

Yes — this freezes well!
Place cooled pasta in freezer bags for up to 2 months.

Reheat:

Warm on the stovetop with a splash of cream or broth to loosen the sauce.

Frequently Asked Questions

Can I use ground turkey instead of beef?

Not by default, but you can adjust the heat level easily.
