Ingredients
- Large portobello mushrooms: Usually these come in packs of two at the grocery store (perfect for this recipe!)
- Olive oil: This will add extra flavor to your filling.
- Garlic cloves: Sautéd with onion, olive oil, fresh, and fresh spinach to enhance the flavor.
- White onion: A small white onion, diced, adds more flavor to the filling.
- Fresh Spinach: Add some greens to your meal with fresh spinach. You can use frozen- just make sure it is defrosted.
- Vegan Feta: This adds a lot of creaminess to the filling. I love Follow Your Heart or Violife.
- Fresh Thyme: This herb pairs perfectly with the portobello mushroom
- Salt and Pepper: Add more to taste based on personal preference

Equipment
- Cutting board
- Chef’s knife
- Large fry pan
- Air Fryer
Instructions
Step 1: Start by heating 1 tbsp of olive oil in a large fry pan over medium heat. Add in diced onion and garlic cloves. Cook for ~3 minutes until onion is translucent.
Step 2: Next add in fresh spinach, thyme leaves, salt, and pepper. Stir and cook down for 1-2 minutes until wilted.
Step 3: Take pan off the heat and add in feta. Stir until combined.
Step 4: Remove the stem of the mushroom. Place stem side up and fill the mushroom with the spinach, feta, onion filling. Add mushrooms in a single layer in the air fryer basket. If your air fryer cannot fit the second mushroom cook a second batch (overcrowding the basket will not allow the hot air to evenly cook the mushroom). Cook for 10 minutes at 400 degrees F. Sprinkle cooked mushrooms with more feta if desired.
Hint: If you have spray oil, consider spraying the sides of the mushrooms before cooking to help it get crispier.

Storage
When storing mushrooms, drain away their juice and store in an airtight container. Excess moisture could create a soggy leftover mushroom. Save the juice for rice, polenta, risotto, soup, and more!
Store leftover stuffed portobello mushrooms in an airtight container for 3-4 days. Reheat in the microwave for 30-45 seconds or in oven at 400F for 5-7 minutes.
I do not recommend freezing leftover mushrooms.
FAQ
Portobello mushrooms are a healthy option on a plant-based diet. This type of mushroom has even higher levels of Vitamin D compared to regular cremini mushrooms. The filling is packed with vitamins from the spinach and onion.
Cook at 400F or 204 C for 10 minutes.
After mushrooms are cooked, they release their natural juices. This is normal and the mushroom will still be hearty and firm if you eat them right after they are cooked.
When storing mushrooms, drain away their juice and store in an airtight container to prevent future sogginess. Save the juice for rice, polenta, risotto, soup, and more!
