Bring a large pot of salted water to a boil for the pasta. Pat the steak dry, trim off any excess fat, and season both sides with salt, black pepper, Creole seasoning, baking soda, and garlic powder if using. Let the steak rest for 10 to 30 minutes while you prepare the other ingredients.


Heat 1 tablespoon of cooking oil in a deep skillet over medium-high heat. Add the steak and sear for about 4 minutes per side, or until nicely browned and cooked to your preferred doneness. Transfer to a plate and let it rest.

Carefully wipe out the skillet, removing any burned bits. Add the remaining 1 tablespoon oil, then add the mushrooms and a small pinch of salt. Cook for about 2 minutes until lightly softened, then transfer to a bowl.

Add the remaining 1 teaspoon oil to the pan and reduce the heat to medium. Cook the onion and garlic for 2 to 3 minutes until fragrant and softened. Stir in the chicken broth and Worcestershire sauce, bring to a gentle simmer, then cook for 5 minutes. Meanwhile, cut the rested steak into bite-size pieces. Cook the pasta in the boiling water according to the package directions, reserving 2 tablespoons of pasta water before draining.



Lower the heat to medium-low and stir the heavy cream and blue cheese into the skillet until the cheese begins to melt. Add the cooked mushrooms, steak, any collected juices, the reserved pasta water, 1 teaspoon salt, 1/2 teaspoon black pepper, and parsley if using. Simmer for about 1 minute, stirring, until the sauce is smooth and heated through.



Add the drained pasta to the sauce and toss until evenly coated. Taste and adjust the seasoning if needed, then serve hot with extra parsley on top if desired.
