Ingredients

12 oz steak (ribeye, sirloin, or filet mignon), cut into bite-sized pieces
8 oz shell pasta
2 tbsp olive oil
3 tbsp unsalted butter
4 cloves garlic, minced
1 cup heavy cream
1 cup freshly grated Parmesan cheese
Salt, to taste
Black pepper, to taste
2 tbsp fresh parsley, chopped (optional)
Reserved pasta water (as needed)

Instructions

Step 1: Bring a large pot of salted water to a boil. Cook the shell pasta until al dente according to package instructions. Reserve ½ cup of pasta water, then drain and set the pasta aside.
Step 2: Pat the steak bites dry and season them generously with salt and pepper.
Step 3: Heat olive oil in a large skillet over medium-high heat. Sear the steak bites in a single layer for 2–3 minutes per side until browned and cooked to your liking. Transfer the steak bites to a plate and cover loosely with foil to keep warm.
Step 4: Reduce the skillet heat to medium. Add butter and minced garlic; sauté for about 1 minute until fragrant.
Step 5: Stir in the heavy cream and bring to a gentle simmer. Gradually whisk in the Parmesan cheese until the sauce is melted and smooth. Season with salt and pepper to taste.
Step 6: Add the cooked pasta to the sauce, tossing gently to coat. If the sauce seems too thick, add reserved pasta water a little at a time until it reaches your desired consistency.
Step 7: Plate the pasta and top with the steak bites along with any juices from the plate. Garnish with chopped parsley if using and serve hot.

Tips & Variations

For extra flavor, marinate the steak bites briefly in a mixture of olive oil, garlic, and herbs before cooking.
Use freshly grated Parmesan for the creamiest sauce—it melts better than pre-grated cheese.
If you prefer a lighter sauce, substitute half the heavy cream with whole milk.
Try adding sautéed mushrooms or spinach to the sauce for extra texture and nutrients.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, adding a splash of cream or reserved pasta water to loosen the sauce as needed. Avoid microwaving to prevent the sauce from separating.

How to Serve

The image shows a white square bowl filled with a dish that has two main layers: on one side, there are creamy, yellow macaroni shells with a smooth, cheesy texture, sprinkled lightly with green herbs. On the other side, there are small, juicy chunks of grilled steak with a dark brown, slightly crispy exterior and a tender, pinkish inside, also garnished with bits of green herbs. The two layers are placed side by side in the bowl, contrasting the creamy pasta with the meaty pieces. The bowl is set on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use a different cut of steak?

Yes, sirloin, ribeye, or filet mignon all work well. Choose cuts that cook quickly and stay tender when cut into small pieces.

How do I know when the steak is cooked properly?

Cook the steak bites for 2–3 minutes per side over medium-high heat for medium-rare to medium doneness. Adjust time slightly for your preferred level, but avoid overcrowding the pan to ensure a good sear.
