Start by seasoning the steak slices generously with salt and black pepper. I heat olive oil in a skillet until it’s hot, then sear the steak quickly to lock in juices. Once browned and tender, I remove it from the pan and let it rest so it stays juicy.
While the steak rests, I bring a large pot of salted water to a boil. The fettuccine cooks until al dente, which keeps it from becoming mushy later. I always reserve a little pasta water before draining, just in case the sauce needs thinning.
In the same skillet, I melt butter over medium heat and add minced garlic. Cooking it gently releases aroma without browning. The garlic-infused butter becomes the foundation for the creamy sauce.
I slowly pour in the heavy cream, whisking constantly to keep it smooth. As it simmers, I add Parmesan cheese and Italian seasoning. The sauce thickens into a silky texture that coats the back of a spoon.
Next, I stir in the gorgonzola, letting it melt into the sauce for bold flavor. The cooked steak goes back into the skillet, soaking up all that creamy goodness. Gentle heat keeps everything tender.
I add the drained pasta directly into the sauce, tossing until fully coated. A splash of reserved pasta water helps if the sauce feels too thick. I finish with fresh parsley and a final taste for seasoning.
