Beef Stroganoff

I have a confession to make.
I love Hamburger Helper.
I know. Shocking. Mrs. Clean Eating loves preservative-filled fake dinner. I've loved it for a long time though, ever since college when I would make it all.the.time. Ask my college roommate, Rachael :) I am particularly drawn to the Beef Stroganoff. I don't know what is it about that ground beef, noodly, creamy goodness that gets me every time.
Anyway, since going clean, HH has not made an appearance in our household. Luckily, I had an old recipe for Easy Beef Stroganoff tucked away and decided to give it the old college try. While it didn't measure up to HH to me, it was still good and easy, just like the name says. Plus, it was all-natural and clean. My kiddos gobbled it up. 
I used all-natural, homemade egg noodles I found at a local meat market. My grandma has a recipe for homemade egg noodles as well, so maybe I'll get brave and try those too. We used the grain-fed beef for the meat, which was also really good and super tender. With this recipe, be sure not to overcook the meat, just cook until barely pink. Otherwise, it gets too tough.

Easy Beef Stroganoff
Adapted from Real Simple

12 ounces egg noodles
2 tablespoons olive oil
1 pound flank steak, thinly sliced
kosher salt and black pepper
1 small yellow onion, thinly sliced
1 green bell pepper, thinly sliced (optional)
2 cups fresh mushrooms
1 8-ounce container all-natural sour cream
2 1/2 tablespoons steak sauce or Worcestershire sauce

Cook the noodles according to the package directions. Meanwhile, heat 1 tablespoon of the oil in a large skillet over medium-high heat. Season the steak with ¼ teaspoon each salt and pepper. In 2 batches, cook the steak until browned, about 1 minute per side. Transfer to a plate.
Return the skillet to medium heat and add the remaining tablespoon of oil. Add the onion and bell pepper (if desired); cook until softened, 6 to 8 minutes. Add the mushrooms and beef and cook until warmed through, about 2 minutes. In a small bowl, combine the sour cream and steak sauce and stir the mixture into the beef and mushrooms. Serve over the noodles.
