Start by bringing a large pot of salted water to a boil, then cook your 10 ounces pasta like linguine according to package directions until al dente. Reserve 1 cup of pasta water before draining the pasta (it will help loosen up the sauce, if needed).
To cook the steak:
Bring the 1 pound rump steaks to room temperature by allowing them to sit on the counter for 15-20 minutes. Season generously with Kosher salt and pepper
Heat the 1 tablespoon olive oil in a large skillet over high heat. Add the steak and cook undisturbed for 4-6 minutes (depending on the thickness), then flip and cook for 4-6 minutes more; drizzle with 1 tablespoon Worcestershire sauce.
Remove the steaks from the pan and let them rest for 5 minutes before slicing thinly.
My steaks are about 1 inch thick, and I cooked them for 6 min, flipped, and cooked for 4 more min for medium.
To make the creamy sauce:
Melt the 2 tablespoons butter in the same skillet you used to cook the steak. Add the chopped 3-4 garlic cloves and cook for 1 minute over medium-low heat. Stir in the 1 1/2 cup low-sodium beef stock and bring to a boil, stirring through the bottom of the pan to deglaze.
Add the 8 ounces cream cheese and stir well until the sauce is smooth.
Add the cooked pasta and stir to coat while still on the heat. The sauce will continue to thicken. Add a bit of the reserved pasta water if the pasta looks too dry.
Remove the skillet from the heat and add the sliced steak, together with all the juices. Sprinkle it with 4 ounces crumbled blue cheese and serve immediately.
Notes
Any pasta will work here, and you do not have to stick with linguine. Also, for a healthier option, feel free to use whole-grain pasta. Lentil or chickpea pasta will work well, too.
For a low-carb option, you can swap the pasta with zucchini noodles.
Instead of olive oil, you can use avocado oil.
Don't like blue cheese, skip it or use crumbled feta instead.
If you have a favorite cut of meat that you would like to use, go right ahead.
