4. Create the Creamy Sauce
Slowly pour in the beef broth while whisking to prevent lumps. Let it simmer for 2–3 minutes until slightly reduced.
Add the heavy cream and milk. Stir well and simmer gently for 5 minutes until the sauce thickens and coats the back of a spoon.
Taste and adjust seasoning with salt and pepper.
5. Bring It All Together
Return the browned beef (and any juices) to the pan. Add the cooked pasta shells and toss gently to coat.
If the sauce feels too thick, add reserved pasta water a little at a time until the desired consistency is reached.
Lower the heat and sprinkle in mozzarella and Parmesan. Stir until melted and silky.
6. Finish and Serve
Remove from heat. Garnish generously with fresh parsley and cracked black pepper.
Serve immediately while hot and creamy.
Flavor Variations
- Spicy Kick: Add extra red pepper flakes or a splash of hot sauce.
- Mushroom Lover’s Version: Sauté sliced mushrooms with the onions.
- Garlic Parmesan Boost: Increase Parmesan and add roasted garlic.
- Extra Cheesy: Mix in fontina or provolone for deeper melt.
Serving Suggestions
- Pair with a crisp green salad dressed with lemon vinaigrette.
- Serve alongside garlic bread or toasted baguette slices.
- A sparkling water or light red wine complements the richness well.
Storage & Reheating
- Refrigerator: Store in an airtight container for up to 3 days.
- Reheating: Warm gently on the stovetop with a splash of milk or broth to restore creaminess.
