Remove the stems from the mushrooms so only the caps remain. Wipe any dirt off the outside of the mushroom caps.
Heat a skillet over medium heat and add the butter, garlic and shallot.
Sauté for 3-5 minutes, until softened and fragrant. Stir in the cumin.
Add the chorizo and cook for 3-5 minutes, until browned.
Turn the heat off and stir in the breadcrumbs and crème fraiche.
Add salt to taste, if desired.
Place 1-2 teaspoons of the filling in each mushroom cap and place in the air fryer basket. (You'll need to air fry in 2 batches).
Air fry at 350F degrees for 5-7 minutes, until the breadcrumbs are toasted and the mushrooms are cooked.
Drizzle with additional crème fraiche and top with crumbled Cotija cheese and chopped cilantro (optional).
Repeat with the second batch.
Notes
While the recipe calls for white mushrooms, you can also use baby bellas. Just make sure the mushrooms you use are large enough to fit 1-2 teaspoons of the filling.
Mushrooms start to brown when bruised or cut, so gently rub any dirt off them.
If you prefer to wash your mushrooms, do so just before using them (they will start to brown otherwise) and make sure they are patted dry with a paper towel.
To ensure the mushrooms cook evenly, air fry them in a single layer.
If you have a large toaster oven style air fryer, you may be able to air fry all of the mushrooms in a single batch. If you have a basket style, you’ll need to air fry them in two batches.
If your air fryer model requires preheating, you should preheat it before adding the mushrooms.
Different air fryer brands and models can vary, so you may need to adjust the temperature and air frying time slightly for these mushrooms.
