Brown the beef

• Heat the olive oil in a large pan over medium-high heat.
• Add the ground beef and let it sit undisturbed so it can brown.
• Break the beef up into crumbles.

Add the vegetables and seasoning

• Toss in the mushrooms and yellow onion.
• Season with salt, thyme, smoked paprika, black pepper and fresh garlic.
• Keep cooking until all the water evaporates.

Thicken with flour

• Sprinkle in the flour and stir to coat.
• Sauté for a minute to remove the raw flour taste.

Build the sauce

• Slowly pour in the beef broth, scraping the bottom of the pan.
• Let the sauce simmer and thicken.
• Stir in the Worcestershire sauce, soy sauce and Dijon mustard.

Add the noodles

• Add the undercooked egg noodles to the sauce.
• Cook briefly so they absorb all of the flavor.

Finish with sour cream

• Turn off the heat.
• Stir in the sour cream until smooth and creamy.
• Serve immediately.
