If you’ve ever had stuffed mushrooms appetizers a party or dinner, then you know how delicious those succulent little devils are!

So, after seeing a few versions pop up on the Internet lately, I decided to make my own, low-calorie Stuffed Mushrooms Casserole that would fulfill all the taste requirements of traditional stuffed mushrooms, but still be a good Weight Watchers Recipe.

I added some savory seasonings like thyme and sage, which remind me of Thanksgiving stuffing. And I used Panko breadcrumbs to keep it light, but still bread-y (yes, that is a word, ok?) It was absolutely delicious! Covered in ooey, gooey mozzarella cheese, and very satisfying, this guilt-free Weight Watchers casserole recipe was a real hit.

It goes perfectly with your favorite chicken or turkey entree and heats up very nicely as leftovers the next day. This Stuffed Mushroom Casserole Recipe an absolute winner.

    This recipe is very good and forgiving if you make a mistake. I am always trying to add veggies to my meals

    How would one go about adding fresh crab to this recipe? I’m challenged to bring a crab dish and this recipe sounds so good….What do you think?

  3. I tried this tonight and it was delish! I’m wondering if you can freeze it for leftovers?

  4. I made this for lunch and it is great. I didn’t have the proper amount of all of the ingredients but it came out great anyway. I used less than 1/4 cup panko, 1 tbsp parm and 1/2 cup mozz on top and it was really good. You can probably cut the ingredients too and save a bunch of calories. The whole recipe ended up being about 600 calories total

    I put all the ingriedients into the weight watchers calculator online and for 6 servings, I’m coming up with 5 points??

      The problem is that I have found the Weight Watchers Recipe Builder to be very inaccurate, as it uses averages of nutritional data from many different brands. When I calculate the Points for each of my recipes, I total up all of the data from the food labels that I use, and then divide it by the number of servings. This is the best way to get the most accurate info, and I encourage you to do the same when making yours. :)

      RE: Points Plus values: WW Recipe Builder will add points for cooked vegetables as a part of a larger recipe, which is probably why you’re getting a higher count.

      Personally, I never count cooked vegetables…
