These simple Vegetarian Stuffed Mushrooms make the best easy appetizer! They are a decadent dish you can feel good about serving.
Eating out has always been one of my favorite things to do.
As someone who does most all of the cooking for a family of five, and who cooks for a living, having someone else cook for me always feels like such a luxury.
And someone serving me and doing the dishes = #myhappyplace.
Even when the kids were little, and we were limited in the types of places that we could go to, I always felt like eating out was a treat.
Now that the boys are old enough to be taken anywhere, and there are only a handful of places that I wouldn’t take Skye, it even feels like more of a luxury.
In all of the years of exploring restaurants all over the U.S., one thing that I’ve observed: the appetizers are usually the best thing on the menu.
I know not everyone agrees with this, but to me, regardless of if I’m eating at a counter service restaurant or fine dining, it is the appetizers that I appreciate the most.
I always joke that I’m just going to order appetizers from now on when we go out, and now and then I do this.
I am always happy with this decision.
I suppose it is no surprise that I adore recipes like these Vegetarian Stuffed Mushrooms.
They are a great make-ahead appetizer, which works just as well for formal entertaining as it does for tailgating or a football party. I am always looking for things that I can have completely ready and heat them when guests arrive, and this recipe fits the bill.
Plus guys – these Veggie Stuffed Mushrooms are so good. Like, hide the leftovers under the kale, so no one else eats them good.
I’ve made a meal out of a few stuffed mushrooms and a side salad more times than I can remember.

Tips for Making Veggie Stuffed Mushrooms
- Don't skip transferring the mushrooms to a paper towel after the first cook. (Prior to stuffing.) The first time I made stuffed mushrooms, I didn't think there was any excess liquid and almost skipped this step. Boy, was I wrong! A few minutes later, the paper towels were completely saturated.
- These stuffed mushrooms may be made up to a day ahead of time. Keep them covered in the refrigerator until you are ready to bake them.
Variations for Vegetarian Stuffed Mushroom Caps
- Buy mushrooms with the caps on. Trim the stems and dice. Cook with the onions for 2 to 3 minutes.
- In place of the cream cheese, use sour cream.
- Sauté’ 1 cup of baby spinach. Use a clean dish towel and squeeze out excess moisture. Chop fine. Add to the sun-dried tomato mixture.
- Omit the cheese and instead top the mushrooms with gluten-free breadcrumbs.
- To make Vegan Stuffed Mushrooms, use vegan cream cheese. (I am a big fan of the Kite Hill brand.) Use either vegan cheese on top or omit the cheese topping and use breadcrumbs.
