Instructions

1. 1Cut the sirloin into 1-inch cubes and season evenly with garlic powder and onion powder.
2. 2Heat a large Dutch oven or heavy-bottomed pot over medium-high heat for 1 minute. Working in two batches to avoid crowding, sear the beef for 4–5 minutes per batch, stirring occasionally, until browned on all sides. Transfer to a plate.
3. 3In the same pot over medium heat, add the cremini mushrooms and cook for 3–4 minutes, stirring occasionally, until they release their moisture and begin to soften. Return the beef to the pot, then add the beef broth, Worcestershire sauce, and Dijon mustard. Stir well to combine.
4. 4Bring the mixture to a simmer over medium-high heat, then reduce to medium-low. Cover and simmer for 45–50 minutes, until the beef is fork-tender and easily breaks apart.
5. 5In a small bowl, whisk the cornstarch with 2 tablespoons cold water to create a slurry. Slowly pour into the stroganoff while stirring constantly over medium heat for 2–3 minutes, until the sauce thickens and coats the back of a spoon.
6. 6Remove from heat and stir in the Greek yogurt until fully combined and smooth.
7. 7While the stroganoff simmers, cook the egg noodles according to package directions in a separate pot. Drain well.
8. 8Divide the cooked noodles evenly among 6 airtight containers while hot, then ladle the stroganoff over the top. Seal and refrigerate for up to 4 days.
