Cook egg noodles according to package directions. Drain and set aside.
Grab a big pan and get some olive oil heating up over medium-high. Add ground beef and cook until no longer pink, about 5-7 minutes.
First, cook the onions for about 3-4 minutes until they're soft, then toss in the garlic and cook for another 30 seconds.
Sprinkle some flour over the beef mixture and give it a good stir to coat it evenly. Cook for 1 minute.
Mix up tomato paste, Worcestershire sauce, thyme, paprika, and beef broth. Stir well to combine.
Simmer for 5-7 minutes until sauce thickens. Season with salt and pepper.
Toss the cooked noodles into the skillet with everything else and mix it up. If using, fold in sour cream.
Garnish with fresh parsley before serving.
