Method
- Bring a large pot of generously salted water to a boil. Cook pasta until al dente, 8 to 10 minutes. Reserve 1/2 cup pasta water before draining. Set pasta aside.
- Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Pat steaks dry, season with salt and pepper, and sear 4 to 5 minutes per side for medium-rare. Transfer to a plate and rest for 5 minutes, then slice thinly against the grain.
- Reduce heat to medium. Add remaining olive oil and butter to the skillet, scraping up any browned bits. Add minced garlic and cook 1 to 2 minutes until fragrant.
- If using beef broth, pour it in and simmer for 2 to 3 minutes. Stir in heavy cream and bring to a gentle simmer.
- Whisk in freshly grated Parmesan until the sauce thickens, about 3 to 4 minutes. Season with red pepper flakes, salt, and pepper to taste.
- Toss the drained pasta into the skillet. Add a splash of reserved pasta water as needed to loosen the sauce to your preferred consistency.
- Gently fold in sliced steak just before serving to warm through. Garnish with fresh herbs and extra Parmesan. Serve hot.
Notes
Storage: Store in an airtight container in the refrigerator for up to 3 days. Reheat on the stovetop over medium-low heat with a splash of water or broth. Substitutions: Swap steak for chicken (165F internal temp) or shrimp. Use half-and-half for a lighter sauce. For a vegetarian version, omit steak and broth, use vegetable broth, and add sauteed mushrooms. Pro tip: Always rest the steak at least 5 minutes before slicing to keep the juices in the meat.
