Start by cutting the steak into small, even pieces to ensure quick and even cooking. Mince the garlic finely and grate the parmesan fresh for the best texture. Boil water for pasta and add a pinch of salt for flavor.
Cook the shell pasta according to package instructions until al dente. Drain it well and set it aside, reserving a little pasta water for later. This helps adjust sauce consistency if needed.
Heat olive oil in a skillet over medium-high heat and add the steak pieces. Cook them in a single layer for a nice sear, flipping once browned. Remove from the pan once cooked to your desired doneness.
In the same pan, melt butter and add minced garlic, cooking until fragrant. Pour in the heavy cream and stir gently to combine flavors. Let it simmer slightly to thicken the base.
Stir in the grated parmesan cheese slowly until it melts into a creamy sauce. Add salt, pepper, and Italian seasoning to enhance the taste. Adjust consistency with reserved pasta water if needed.
Add the cooked pasta and steak bites back into the skillet. Toss everything together so the sauce coats each piece evenly. Let it cook for a minute so flavors fully blend.
Sprinkle chopped parsley on top for freshness and color. Serve immediately while hot for the best creamy texture. Enjoy every rich and buttery bite.
