3. Grab Your Baking Sheet

Lay the baking sheet down on your tray and spray down with a light spray of avocado oil.

4. Lay Out the Mushrooms

Carefully arrange the portobello mushroom slices on the baking sheet. Make sure there’s a small amount of space around each slice so they’re not touching. Give them a spray with the avocado oil and season with a sprinkling of salt and pepper.

Common Questions

There’s more than one way to bake a chip! Let’s dive into some common questions so you can become a confident low-carb chip master in no time.

Are Mushroom Chips Keto-Friendly?

This Mushroom Chips recipe is definitely suitable for a low-carb diet. We have a full article answering the question “Are Mushrooms Keto?”

Mushrooms are incredibly low in net carbs, but high in fiber – and a rich source of antioxidants, too!

However, the same isn’t always true for store-bought Mushroom Chips.

Some packet varieties contain added net carbs, usually from a starch-based coating. Be sure to check the ingredients to make sure your chips contain only mushrooms, oil and seasoning.

And just like potato chips, they’re often made with highly processed seed oils like sunflower oil. Hydrogenated oils like these have been shown to increase inflammation in the body and are usually avoided on a keto diet.

Our crispy Mushroom Chips recipe is made using avocado oil, which is actually high in antioxidants. You can read more about our recommendations for cooking oils in our guide here.

While you could use olive oil in a pinch, we think the flavor of avocado oil goes much better with these mushroom chips than olive oil.

This is why you should always check the nutrition label before purchasing any seemingly low-carb product. Or, you could just make your own with this amazing recipe!

Are Potato Chips Too High in Net Carbs for a Keto Diet?

Unfortunately, potatoes are pure carbs, which means regular potato chips are definitely not suitable for a keto diet.

While some higher-carb foods can be enjoyed in small amounts on keto, this just isn’t the case for otto chips. One small snack-sized bag of chips contains around 20 grams of net carbs alone! 

Sure, you could try to limit yourself to just a couple of chips. But be honest: do you really have the willpower to stop yourself from eating the entire bag?

More importantly, does that sound remotely satisfying? 

We’d much rather stick to our homemade low-carb Mushroom Chips, thank you very much.

How Do I Make Crunchy Mushroom Chips?

A crunchy chip is the best kind of chip. So what’s the trick to achieving that perfect crispy texture?

This recipe uses the low-and-slow cooking method. This ensures the mushroom slices cook slowly without burning, producing a crunchy end result.

The spray oil is also key to achieving the right texture. Too much oil can create a soggy chip, while a light spray ensures each slice cooks evenly.

Take care not to slice your mushrooms too thick. You want each slice to be nice and thin so it crisps up.

You could also use an air fryer to get extra crispy chips.

How Do I Store My Low-Carb Mushroom Chips?

Store your chips in a sealed, air-tight container to make sure they stay nice and crisp.

These crispy chips really are best enjoyed the same day, as they may be less crunchy the next day. However, they’re so moreish you probably won’t be able to save any for later!

Can I Use Other Kinds of Mushrooms?

Yes! Feel free to experiment and try different mushroom varieties for this recipe. Mix it up with some pearl oysters, porcinis, or – if you’re lucky enough to get your hands on them – some beautiful golden chantarelles.

One thing to keep in mind: the mushroom slices do shrink considerably when baking. Try to choose larger mushrooms that will hold up. 

Using small button mushrooms may leave you with some very tiny chips!

How Should I Serve My Mushroom Chips?

We think these Mushroom Chips are super delicious seasoned with just salt and pepper. Mushrooms have an amazing umami flavor, which makes this recipe absolutely perfect for dipping!

Try some of these keto-friendly dips:

  • Queso
  • Sugar-free salsa
  • Guacamole
  • Greek yogurt or sour cream with ranch dip mix stirred through
  • Pesto

Seasoning Ideas

Want to get a little creative with your Mushroom Chips? Feel free to experiment with different seasonings.

Try adding fresh or dried herbs, seasonings or even flavored spray oils if you can find any. These would also taste amazing made with garlic or basil-infused avocado oil!

Here are some flavors to try:

  • Salt and vinegar – add a spritz of white vinegar just before they’re done cooking.
  • Italian – try herbs like rosemary and oregano.
  • Mexican – add a good shake of smoked paprika, cumin, garlic powder and onion powder.
  • Cheese – sprinkle with powdered parmesan or even nutritional yeast before serving.
  • Truffle – add some truffle salt before cooking for an extra-fancy flavor.
