Vegetarian Stuffed Mushrooms (2024)

You are going to fall in love with these Vegetarian Stuffed Mushrooms. They are quick to make and even quicker to disappear. Perfect for entertaining since all the prep-work can be done in advance. This is one I turn to again and again!

Vegetarian Stuffed Mushrooms are a great make-ahead appetizer.

They work just as well for formal entertaining as they do for tailgating or a football party. (I've served this for Thanksgiving, Christmas, game day parties, and summer gill outs!)

If you are looking for an appetizer that you can have completely ready and heat when guests arrive, this recipe fits the bill.

Plus, 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.

Give this a try and I think it will become one of your favorite mushroom recipes.

Step By Step

For the full recipe with measurements, see the recipe card at the bottom of the post.

First, preheat the oven to 400 degrees.

Clean the mushrooms with a clean damp cloth or damp paper towel and place them on a parchment-lined baking sheet, stem side down. Cook for 6 minutes.

Remove from the oven and place on paper towels to drain.

Next, gather your ingredients for the filling.You will need avocado oil, red onion, sun-dried tomatoes, garlic, cream cheese, and Parmesan cheese.

Heat the avocado oil in a skillet. Add the onion and cook for 6 minutes. Add the sun-dried tomatoes and cook for another two minutes.

Finally, add in garlic and season to taste with salt and pepper. Cook for another 30 seconds.

Remove from heat and add the mixture, along with the cream cheese, to a food processor.

Pulse until combined and spoon the mixture into the mushroom caps. Top with Parmesan cheese and broil for 3 to 5 minutes.

Top with parsley and serve warm.

Tips for Making Veggie Stuffed Mushrooms

• Don't skip transferring the mushrooms to a paper towel after the first cook. (Before 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.
• Olive oil may be used in place of avocado oil.

Variations

• If you buy mushrooms with the stems on trim the stems and dice. Cook with the onions for 2 to 3 minutes. This will make for "meatier" vegetarian stuffed mushroom caps.
• 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.
