1/2 cup grated Parmesan cheese, plus more for serving
Salt & pepper, to taste
2 Tbsp chopped fresh parsley (for garnish)
Instructions
Cook rigatoni in salted boiling water according to package directions until al dente. Reserve 1/2 cup pasta water, then drain.
While pasta cooks, pat steak slices dry and season with salt and pepper.
Heat olive oil and 2 Tbsp butter in a large skillet over medium‑high. Sear steak slices in batches for about 2 minutes per side until browned but still medium‑rare. Transfer to a plate and cover to keep warm.
