Are mushrooms keto?

Cleaning portobello mushrooms
Mushrooms are a vegetable that need to be cleaned as even the prewashed ones will have a trace of dirt on them.
Although some people will wash their mushrooms under cold water, this can remove nutrients and should only be used if your mushrooms are utterly covered in dirt. If you do this, dry them thoroughly as a soggy mushroom does not cook as well.
Using a damp cloth or kitchen towel and gently clean the mushrooms without bruising them.
How to cut a portobello mushroom
Remove the stems with a pairing knife and then remove the dark gills from the underside of the mushroom caps by scraping them off using the edge of a teaspoon.
Place the mushroom cap upside on a chopping board. Using a sharp knife, cut the mushroom in half. Then those halves are cut into even strips

How to make keto air fryer portobello mushroom fries
We made these mushroom fries in the air fryer but they can be baked in the oven too. Instructions for baking are in the recipe card.
The easy step by step instructions are below.
- Prepare your dipping station with the beaten egg in one shallow bowl, and the seasoned almond flour in another shallow bowl.
- After washing and slicing the portobello mushrooms, tip into the beaten egg. Use tongs as your fingers will get sticky and messy if you use your hands.
- Dip into the seasoned almond flour and cover thoroughly.
- Once all the slices are covered, pre-heat the air fryer (baking in the oven instructions are in the recipe card below).
- Place the mushroom slices in the air fryer basket and cook for 10 minutes.
- Serve with a dip.
Can you make these mushroom fries vegan?
If you want low carb vegan mushroom fries you will need to omit the egg. The slices of mushrooms will need moisture for the coating to stick so try almond milk or even coconut milk in place of the egg.
For the coating, add nutritional yeast for an extra cheesy flavour.
What to serve with mushroom fries
However delicious these easy low carb mushroom fries are by themselves, they are great with a dip. Just as all fries are! Try them with homemade mayonnaise or a ranch dressing. They go with any low carb sauces!
Add a grated vegetarian parmesan cheese to the almond flour coating or nutritional yeast. The seasonings can be changed. We made a batch flavored with cayenne pepper was were fantastic.
Removing the gills is entirely optional are they are edible. They give a richer, earthy flavor which some people don't like. We've tried the fries with and without and enjoyed both batches.
Turn these portobello mushroom fries into loaded fries by adding grated Cheddar or Mozzarella cheese on top once they are cooked. Then cook for a further 3-5 minutes until the cheese has melted. Serve with chopped onion and sour cream.
