Easily prepped ahead of time, vegan stuffed mushrooms can be made and cooked conveniently.  Regardless of the type of stuffing, my vegan stuffed mushrooms hold all the flavors inside their great caps. 

For this vegan stuffed mushroom recipe, however, I provide a few options for fillings to give you several meal options in one vegan stuffed mushroom recipe. 

Selecting Portobello Mushrooms

When shopping for portobello mushrooms, avoid any spots indicating the beginning of rot. Instead, look for caps that are firm and uniform in color.  And look for dry mushrooms, not ones that appear wet or slimy.  

For example, I prefer lighter-colored mushrooms instead of darker ones for a more delicate flavor.  On the other hand, if you prefer a deeper earthy taste, look for darker mushrooms, but be careful of spots and texture.

Sometimes, a darker mushroom can appear dry, but it may be starting to get slimy, and no one likes slimy. 

How to Store Portobello Mushrooms

Once you get the portobello mushrooms home, please place them in the refrigerator in the packaging. But, if you selected the mushrooms yourself, without packaging, do not leave them in a plastic bag.  

Plastic bags, for instance, break down the mushrooms causing them to smell and get slimy.

Again, to avoid the slime, place the portobello mushrooms in a paper bag, such as a lunch bag, until ready to use. For the best results, store the mushrooms in a paper bag to prolong freshness when purchased without packaging.  

Cleaning and Removing the Gills

To remove the gills, turn the cap over to the open side, and carefully remove the gills by scraping the gills with a small spoon. Then, make sure you use minimal water and a paper towel to dry.

Even though the gills are edible, they produce a yucky brown residue that makes a mess of your plate.

Stuffing Options

• White Onion: White onion, although sharp in flavor, caramelizes nicely when sauteed.
• Shallot:  Shallots also have a mild, somewhat sweet flavor, which is more subtle than the sharp, pungent taste of onions.
• Garlic: Garlic contains antioxidants that support the body's protective mechanisms against oxidative damage. 
• Mushrooms: Yes, mushrooms are part of a stuffing for going inside mushrooms. When diced and sauteed with the other ingredients, it is delicious inside of a larger mushroom.
• Fresh Rosemary: Rosemary is one of the most aromatic herbs and has an equally pungent taste. The flavor is lemony-pine-like and has also been described as minty, sage-like, and peppery.
• Brown Lentils: I love the brown lentils from Trader Joe's that are pre-cooked and steamed.

Making the Stuffing

Regardless of your stuffing choice, each recipe offers a different recipe for vegan stuffed mushrooms. For each recipe:

• Saute diced onion, shallot, and garlic
• Use a small amount of vegetable broth if the vegetables begin to stick
• Add remaining vegetables and cook a few more minutes
• Add cooked lentils, vegan sausage, or rice, or potatoes
• Add herbs
• Stir together until combined
• Wait until cool to the touch to stuff into the mushroom caps

Preparing and Cooking the Stuffed Mushrooms

Clean the portobello mushrooms and remove the gills, then pre-bake the mushrooms to remove some moisture before stuffing them. So, first, line a baking sheet with a silicone baking mat or parchment paper.

Next, place the mushrooms, opening down, on a baking sheet. Then, cook in a 300-degree preheated oven for 15 minutes. 

Remove the portobello mushrooms from the oven, place them on a paper towel to cool, and discard the juice from the pan. When cooled, stuff each cap full with the chosen stuffing mixture.

Now, cook the vegan stuffed mushrooms immediately or put them in the refrigerator for up to a day before cooking.

Tips

• Use the edge of a spoon to remove the gills from the inside of the mushrooms. Avoid breaking through the mushrooms.
• Dry and wipe washed mushrooms with a paper towel before cooking to keep stuffed mushrooms from getting soggy. 
• One idea to serve with vegan stuffed mushrooms is butter bean mash with easy no-chicken gravy. Another idea is vegan mashed potatoes or scalloped potatoes.
• Reheated stuffed mushrooms should be left to reach room temperature before storing them. They should be stored in an airtight container and kept in the refrigerator. Stuffed mushrooms can last for 3-5 days when properly cooked and stored in the fridge. 
• Generally, reheating stuffed mushrooms once or twice should retain their enjoyability, but reheating them too many times can cause them to become dry, chewy, rubbery, or hard.
