When it comes to comfort food, it’s tough to beat beef stroganoff; and the Bring Your Lunch! cookbook has an easy, creamy, noodley recipe for you. If you have leftover steak or pot roast on hand, this recipe will come together in a matter of minutes. While they’re not required, a few cooked mushrooms add an extra savory dimension, so toss those in, too, if you have them.
The stroganoff can be assembled the night before. Keep (chilled) in a microwave-safe, leak-proof glass container. When you’re ready to eat, microwave on full power until warmed through, no more than 2 minutes, or warm gently in a skillet, about 5 minutes. Stir well.
Stir together the sour cream, mustard, Worcestershire, and half of the dill in a microwave-safe, leak-proof glass container. Season with the pepper and salt, if needed.
Add the beef and noodles and toss to combine. Top with remaining dill.
