I love a good cheesesteak sandwich, but honestly I can’t tell you the last time I had one because the average cheesesteak contains 900 calories, 40 g of fat, 50 g of protein and 80 g of carbohydrates which is fine for an occasional indulgence, but not something I would want to eat everyday.

This lighter version is still decadent, yet has plenty of vegetables to balance it out. I’m sure this would also be great with chicken if you prefer. Serve it with a big salad and call it a meal!

  1. I made these super easy with sliced rare roast beef from the deli instead of cooking steak. Used some sliced provolone chopped up in the mix and then topped each mushroom with a slice during the last 5 minutes. Rich and delish. Husband loved them. Wants them again soon. Yay!

  2. I was so sadly disappointed in this recipe, especially based on all the amazing reviews. I followed the recipe, but my mushrooms ended up in a pool of liquid on the baking sheet when they were done. I don’t know if it was liquid from the mushrooms, the meat, or the vegetables. I also just didn’t think it had a lot of flavor (and I even added the suggested 1 T Worcestershire that reviewers mentioned). Sirloin isn’t a particularly tender or desirable cut of beef anyway, so it was also pretty tough and chewy, despite cooking it as directed. I think there’s a lot of potential here so I may try again with ground beef, bake the mushrooms on a baking rack over a cookie sheet, and tweak the other ingredients a bit to give more flavor.

  3. This looks absolutely delicious and I can’t wait to try it this weekend! I have one question: is it 6 oz steak total or each mushroom?
