Gluten-free stuffed mushrooms. Vegan recipe that is low calorie, low carb, paleo and Whole30 compliant. All that and tasty too! Everything you want in a hard working vegetarian appetizer recipe and nothing you don’t!
Low in carbs and calories, but BIG on taste! The perfect little appetizer….that just so happens to be healthy too!
This easy recipe is so delicious, I often use large portobello mushrooms and make it into a vegan main dish.
Vegan stuffed mushrooms are perfect for appetizers, snacks or even a vegetable side dish. I wish veggies were so beautiful and tasty when I was growing up!!!
What’s in these vegan mushroom appetizers?
What if I don’t have all the ingredients?
- Mushrooms: I made these with portobellos, but you can also use button mushrooms or cremini. I just love a stuffed mushroom appetizer, don’t you? If you don’t have mushrooms, use zucchini! (scoop out the center…follow all the same directions, but they will need 5 minutes less cooking time. Zucchini boats are equally fun and delicious.
- Cauliflower rice: You can substitute riced broccoli, or parsnips for the cauliflower. Really, any riced veggie will work well. OR, use a cooked grain like wild rice or quinoa….they’ll still be gluten-free.
- Pine nuts: any nut or seed will work. Cashews or walnuts would be good choices. Or if allergic to tree nuts, try hemp seeds, pumpkin seeds or sunflower seeds.
- Onion: If you only have a red onion, use it! Leeks would work, as well as scallions or even shallots.
- Greens: I used spinach and parsley, but any fresh herbs will work well. I’ve made this with fresh basil and oregano before. Cilantro is another good choice. Maybe you have some chives growing wild in your yard? If you don’t have any fresh herbs, or you have some, but not quite enough, substitute 1 teaspoon dried herbs for each Tablespoon fresh you’re trying to replace. I would add in a bit of kale or another green for color and nutrition, if you have it.
- Nutritional Yeast. If you don’t have any or you’re making this for Passover, simply omit. Taste the stuffing after it’s done, before you stuff the mushrooms, you may want to add a bit more salt to compensate.
How do you make gluten-free stuffed mushrooms?
STEP 1: Remove the stems to par-bake mushrooms before stuffing. Mince the the stems and set them aside.
STEP 2: Pulse the nuts and spices until crumbly. I use a spice grinder to make this super easy. If you don’t have a spice grinder, use your coffee grinder or a small food processor. You can also chop by hand, if you don’t have any of those small appliances. Set aside 1 Tablespoon to use later to sprinkle over the tops of the stuffed mushrooms.
STEP 3: Make sure your ingredients are all ready before you begin to cook. You won’t have too much time between steps so, you’ll definitely want to prep before you start.
STEP 4: Prepare the vegan stuffing. Super easy, now that everything is prepped. Saute the onions and mushroom stems, grate the garlic over the pan, add in the greens and nuts, then stir.
STEP 5: Fill the par-baked mushrooms. I find this easiest to do using two spoons. Just the way you would drop cookies onto a tray. Scoop with one spoon and then nudge the gluten-free stuffing off and into the mushroom with the back of the other spoon.
STEP 6: Sprinkle the remaining nut mixture over the tops. Put the stuffed mushrooms back into the oven for another 15 minutes.
STEP 7: You’ll know when they’re done because they’ll be golden on the top.
How to serve stuffed portobello mushrooms:
- APPETIZER. Think: pot-luck, holiday party healthy hors d’oeuvres, Thanksgiving appetizers, brunch, girls night out, whole 30 appetizers.
- SIDE DISH. Yummy low carb veggie side dish. Perfect for those who are paleo, and folks who want to get in their veggies, but not at the cost of yummy.
- MAIN COURSE. Yes, please. Give this to me for any meatless monday and I’d be a happy camper. Full sized stuffed portobello mushrooms are so satisfying, super delish and something everyone can indulge in.

- 14 ounces portobello mushrooms (approximately 16 medium sized)*
- 2 Tablespoons olive oil
- 1 small onion, small dice
- 2 cloves garlic
- 1/4 teaspoon sea salt
- 1/4 teaspoon black pepper
- 3/4 cup cauliflower rice
- 2 Tablespoons finely chopped parsley*
- 2 Tablespoons finely chopped fresh spinach*
- 1/3 cup pine nuts*
- 1 teaspoon dried oregano
- 1 teaspoon onion powder
- 1 teaspoon garlic powder
- 1/2 teaspoon coarse sea salt
- OPTIONAL: 2 Tablespoons nutritional yeast
- Preheat oven to 350. Line rimmed baking tray with unbleached parchment paper.
- Clean mushrooms with damp paper towel. Remove stems, mince and set aside to include in filling.
- Place mushroom caps upside down (so removed stem is face up) on prepared baking tray. Brush with 1 Tablespoon olive oil, or use an olive oil spray. Bake for 10 minutes to soften.
- MAKE THE "CHEESE": Use a coffee or spice grinder, small food processor (or a sharp knife and some elbow grease) to combine nuts, oregano, onion powder, garlic powder, salt and optional nutritional yeast. Pulse until crumbly and resembling parmesan cheese. Set aside.
- MAKE THE FILLING: In a heavy skillet over medium heat, swirl in remaining 1 Tablespoon oil, add in the reserved minced mushroom stems and diced onions. Cook, stirring often for about 3 minutes while stems release their juices. Sprinkle with S+P, grate garlic over pan and continue to cook, stirring for 2 more minutes while onions continue to soften. Stir in cauli-rice until well incorporated. Turn off heat. Mix in all but 1 Tablespoons (set aside for topping) of nut mixture, and the spinach/parsley.
- Scoop filing into the par-baked mushrooms. It's Ok to overstuff. Sprinkle with the nut mixture you set aside and bake for 15-20 minutes, until mushrooms are tender and topping is golden.
- White button mushroom will also work well. Also, you can stuff larger portobello mushrooms and serve as a side dish.
- Any combo of fresh herbs and spinach will work. I used 2 Tablespoons fresh parsley and 2 Tablespoon chopped spinach.
- If you don't have pine nuts, cashews are a good sub...but, any nut or seed will do.
