  • Cook the egg noodles for one minute less than instructed on the package. Drain and set aside.
  • Heat the olive oil over medium-high heat in a Dutch Oven or large pot. Add the ground beef and cook and crumble until it’s browned and cooked through.
  • Remove the cooked beef from the pot and set aside, leave the grease in the pan.
  • Add the onion to the pan and sauté over medium heat for 5 minutes, until soft and translucent.
  • Add the minced garlic and cook for additional minute, until fragrant.
  • Add the butter to the pan and swirl around until it’s melted.
  • Use a fork to stir in the flour and cook for 1 minute, stirring continuously.
  • Stir in half of the beef broth until incorporated, then add the second half.
  • Use a spatula to scrape up the brown bits from the bottom of the pan, this will give the sauce plenty of flavor.
  • Mix in the sour cream and mustard until well-combined. (Sour cream will keep melting and will eventually incorporate into the mix.) Let it simmer for 3-5 minutes, until thickened.
  • Add the ground beef back to the sauce. Use a silicone spatula to carefully mix in the egg noodles.
  • Pour into a 9x13 greased casserole dish and top with cheese.
  • If serving immediately, bake uncovered at 375 degrees for 15 minutes, until the cheese is hot and melted.
