The ingredients
Portobello Mushroom Caps – Bigger, meatier mushrooms that hold up beautifully in the air fryer.
Worcestershire Sauce – Adds that deep, umami kick. Make sure it's vegetarian if needed!
Olive Oil – Helps the mushrooms crisp and soak up all the marinade.
Garlic Powder – For that mellow garlic flavor without the bite.
Salt – Just enough to bring everything to life.
Fresh Parsley – Optional, but makes everything look chef-y.
Step-by-Step Instructions for the Air Fryer Portobello
Clean the mushrooms.
Gently rinse your portobello caps and pat dry. If they have long stems, trim them back.
Make your marinade.
In a small bowl, stir together Worcestershire, olive oil, garlic powder, and salt. That’s it!
Prep the air fryer basket.
Give it a quick spritz with olive oil spray so nothing sticks.
Brush the caps.
Coat the tops of your mushrooms with the marinade using a brush or spoon. Place them gill-side up in the basket and pour the rest into those gills—flavor central.
Let the air fryer do its thing.
Cook at 400°F for 3 minutes. Flip them over and go another 3–4 minutes. You want them browned, tender, and juicy.
Add the final touch.
Let them rest a minute. Then sprinkle with fresh parsley and serve them hot.
Tips for Success
- Don’t skip drying. Mushrooms soak up water like sponges. A quick towel pat keeps them from steaming.
- Use tongs to flip. Portobellos can be delicate when hot.
- Watch cook time. Thicker caps might need an extra minute or two.
- Want crispier edges? Add a bit more oil to the gills!
Variations
- Make it spicy. Add chili flakes or a dash of cayenne to the marinade.
- Cheesy mushrooms. Sprinkle with Parmesan or vegan cheese right after air frying.
- Balsamic glaze. Drizzle some over the top for a tangy finish.
Serving Ideas
- On top of creamy mashed potatoes.
- Sliced into a wrap or sandwich.
- Served whole beside grilled chicken or steak.
- Chopped into a grain bowl with rice and hummus.
- With a drizzle of tahini and a sprinkle of za’atar.
Storage Tips
- Fridge: Store leftovers in an airtight container for up to 3 days.
- Reheat: Air fry at 350°F for 2–3 minutes or microwave in 30-second bursts.
- Freezing not recommended, they’ll go mushy.
FAQs
Yes, just reduce the cook time by a couple minutes since they’re smaller.
Totally! Mix the marinade and clean the mushrooms the day before. Store separately and assemble when ready to cook.
Yep! It'll still be umami-packed, just slightly different in depth.

Just made these again last night and wow—still one of my favorite ways to enjoy mushrooms! The air fryer makes them so juicy and flavorful in hardly any time. I served mine over quinoa with a drizzle of balsamic glaze.
