Instructions
In a large skillet with deep sides over medium heat, add 3 tablespoons of the butter and melt.
Add the onion, baby bella mushrooms, white button mushrooms, salt, and pepper. Stir to coat in the butter and cook until the onions are translucent and the mushrooms are softened, 5 minutes.
Place the mushrooms/onions onto a plate and set aside.
Return the pan to the stovetop over medium-high heat, add the ground beef and brown the meat, breaking it up with a wooden spoon.
Drain any excess water or fat off the meat and add the butter to the pan, let melt.
Add the flour and stir to combine. Slowly add in the beef stock, one cup at a time, and stir it in until combined with the flour and the meat.
Let it come to a simmer and slightly thicken. Add the Worcestershire sauce and mushroom mixture back to the pan.
Stir in the sour cream and stir until just warmed through. Add the 1 tablespoon of the parsley, stir to combine.
Serve the sauce over the cooked egg noddles and garnish with more fresh parsley if desired.
