Ingredients to make Vegetarian Stuffed Mushrooms

Raw stuffing mushrooms before cleaning and hallowing out
  • Mushrooms: Use medium-size mushrooms like white mushrooms or crimini (baby bella) mushrooms. Look for mushrooms that are free from blemishes and soft spots. Removing the stems creates space for the delicious filling.
  • Chickpeas: Creates a flavorful base for the filling, adding protein and satisfying texture. Drain canned chickpeas well or easily cook chickpeas at home.
  • Walnuts: Adds a nutty crunch and richness to the veggie stuffed mushrooms, adding a nice contrast to the smooth texture of the chickpea paste.
  • Parmesan cheese: Used in the chickpea stuffing mixture and as a topping, grated Parmesan cheese adds a savory and cheesy note to this appetizer.
  • Onion and Garlic: Sauteed onion offers a slightly sweet note, while garlic adds an aromatic element. Both enhance the overall flavor of these meatless stuffed mushrooms.
  • Olive oil: Used for sauteeing the onions, mushroom stems, and garlic, adding moisture and flavor to the filling.
  • Herbs: Fresh thyme and parsley add a herbaceous flavor, complementing the richness of the other ingredients.
  • Balsamic vinegar: Though balsamic vinegar is optional, it brings a wonderfully tangy and slightly sweet note to the filling that rounds out the overall flavor. The liquid of the vinegar also helps to stir the filling.
  • Try other nuts. Pecans, almonds, or even pine nuts can replace walnuts, each providing a unique and nutty twist to the taste. Toast pecans before adding them to bring out the nuttiness.
  • Add a healthy grain. Include cooked quinoa or couscous into the chickpea mixture for added texture and protein. It will also give these vegetable stuffed mushrooms a satisfying feel.
  • Experiment with seasonings. Add a dash of seasoning like herbes de Provence, ranch seasoning, or even lemon pepper seasoning for a different flavor profile.
  • Make it vegan by skipping the cheese. This recipe is easily adaptable to become vegan. Just skip the parmesan cheese from the mixture and the topping. You can also use a good vegan alternative, nutritional yeast, or breadcrumbs.
  • Have fun with toppings. Once plated, serve these veggie stuffed mushrooms with a drizzle of balsamic glaze or fresh herbs like basil, parsley, or thyme. Or give it a refreshing flavor by adding a pinch of lemon zest to each mushroom cap and serve with lemon wedges on the side.

How to make vegetarian Stuffed Mushrooms

These vegetarian stuffed mushroom caps start with preheating the oven with a baking tray inside. Then, sauteed mushroom stems, onions, and garlic join forces with a blend of chickpeas, walnuts, and thyme and are baked to golden brown perfection.

Prepare stuffed mushroom mixture

  1. In a frying pan over medium heat, heat the olive oil. Add the diced onions, mushroom stems, and garlic and saute until fragrant and slightly reduced.
  2. Add the walnuts and thyme.
  3. Stir and continue to cook to toast the walnuts slightly.
  4. In a small bowl, combine the chickpeas, parmesan cheese, parsley, balsamic vinegar, salt and pepper.
  5. Using a fork, combine and mash to form a paste-like mixture.
  6. Transfer the sauteed onion mixture to the chickpea mixture and stir to combine well.

How to bake stuffed mushrooms

  1. Remove the baking tray from the oven and carefully place the mushroom caps on the baking sheet. Spray with cooking spray. Spoon the filling into the mushroom caps and top with the remaining parmesan cheese.
  2. Bake in the preheated oven until the mushrooms are cooked through, and the cheese has melted. Serve warm.

Tips for making the best vegetarian stuffed mushrooms

  1. Choose mushrooms that are the same size. You can usually find “stuffing mushrooms” this time of year that are the perfect size and even. If you don’t, just try to pick ones that are as similar as possible so they cook evenly.
  2. Wipe the mushrooms clean with a damp paper towel. I recommend that you don’t rinse your mushrooms. If you rinse them, their spongy texture will soak up too much liquid. And that can lead to soggy mushrooms.
  3. Cook mushroom stems, onions, and garlic before adding walnuts and herbs. It’s tempting to throw everything together in a pan and fry it to make the stuffed mushrooms. But the walnuts will get powdery if you add them to the pan immediately. Keep them and the herbs until the end for the best texture and flavor.
  4. Skip the parchment paper. I know that adds to the clean-up, but it’s best not to use the parchment paper so the mushrooms don’t sweat too much. Plus, when we place the mushroom caps on the hot baking sheet, it creates a nice sear on the bottom and prevents sogginess.
  5. Keep an eye on the mushrooms as they bake. Once the cheese is melted and the mushrooms are tender, they are ready to be pulled out of the oven. Overbaking mushrooms will make them rubbery and will dry out the stuffing.

How to store & reheat Vegetarian Stuffed Mushrooms

Leftover stuffed mushrooms can be stored in an airtight container in the refrigerator. To reheat, place the mushrooms on a baking sheet and heat in a preheated oven until they are warmed through. You can also reheat in the microwave in 30-second intervals, but I recommend the oven method to help maintain the crispy texture.

How long will vegetarian Stuffed mUshrooms last in the fridge?

These stuffed mushrooms will last in the refrigerator for up to 4 days.

Can I freeze Stuffed Mushrooms?

You can make these vegetarian stuffed mushrooms ahead of time and freeze them. Stuff the mushrooms, but don’t bake them. Freeze them on a baking sheet, and once frozen, you can transfer them to a freezer bag and store them for up to three months. When ready to enjoy, bake them from frozen adding a few more minutes to the cook time.

Frequently asked questions

What kind of mushrooms are best for stuffed mushrooms?

I like to use medium sized mushrooms for stuffing – nothing too big like a portobello as I want them to be served as finger food, and nothing too small so that I can load them with the stuffing! Crimini (baby bella) or white mushrooms both work well. If you want to serve this as a sit-down appetizer with a salad, you can then of course use a portobello mushroom.

Are vegetable stuffed mushrooms a healthy appetizer?

A serving size of 3 vegetarian stuffed mushroom caps has a good amount of protein and fiber, thanks to the chickpeas and walnuts. These mushroom bites are a great appetizer to serve while everyone is waiting for the main course.

Can I make stuffed mushrooms ahead of time?

Yes, you can bake them per recipe and store them in an airtight container in the fridge for up to 4 days. But I recommend prepping the mushrooms and keeping them unbaked in the fridge for up to 24 hours. Then when ready to enjoy, bake them according to recipe instructions, and they will be just as delicious!

  1. Liked by all, even the carnivores. I used wonton wrappers with some leftover filling, and that was a huge hit too. Time-consuming, but worth it.

  2. The recipe is OK, but for the love of cooking, please add a recipe jump. In most cases, the first thing a person ever cooks isn’t going to be stuffed mushrooms, and we don’t need a novella, just the recipe. I know you’re trying to make as many slots for ads as possible, but honestly, it’s too much.

    1. Hi Laura, I understand the frustration of having to scroll when you just want to get to the recipe. I actually do have a “Jump to Recipe” button on all of my posts just for that reason. It’s a black, square button at the top of the page next to the sharing options that says “Jump to Recipe.” I hope that helps you navigate the page easier.

  3. These mushrooms were delicious. And the mix of textures from the chewiness of the mushrooms and cheese to the crunchiness of the toasted walnuts worked so well together. It’s definitely a repeater!

  4. Made these for a holiday party this year, and they were ok. They were pretty bland, I added in the balsamic dressing and took the advice of another reviewer and added sun-dried tomatoes to the chickpea mash. Still it was lacking much flavor. The recipe itself is also missing directions – had to go back to the “story” to read when to add the balsamic dressing and how to split up the parm cheese.

    1. Thank you for your feedback! When you cook the onions and mushrooms, you can add in more ingredients/ seasonings then because this is where all the flavor in the dish comes from.
