Prepare pasta to al dente following package direction using a large pot and salted water. Drain, toss in olive oil and set aside until you need it.
In a large skillet, add vegetable oil and heat over medium-high heat.
Pat the steak dry. Lightly salt and pepper the steak pieces.
Add the steak to the hot oil and sear for 2-3 minutes, rotating each cube 1-2 times until the pieces start to turn golden brown.
Remove steak and allow it to rest on a paper towel lined plate while you make the sauce.
To the skillet, add onions and mushrooms. Sauté for 3-5 minutes until caramelized and fragrant.
Add can of soup, broth, sour cream and spices. Stir briskly to incorporate and heat over medium-low heat until bubbling.
Return steak to the skillet. Add cooked pasta, stir to coat.
Serve warm, topped with parmesan cheese and a sprinkle of fresh herbs.
Notes
You can really use whatever pasta you like, but I recommend using something that is a "tube" shape to allow the sauce to fill the pasta.Reserve 1/2 cup of salted pasta water to use just in case your sauce is too thick.
