Frequently Asked Questions

Can I use real blue cheese?

Of course. You can use any type of real cheese or vegan cheese you prefer in this recipe. If you are using real cheese there’s no reason to use nutritional yeast as well.

What to do if I don’t have nutritional yeast?

If you don’t have nutritional yeast don’t worry. It’s an optional extra ingredient that adds a layer of cheese flavors to the dish, but it can easily be left out of the recipe.

Can portobello mushrooms be reheated?

Yes. Mushrooms are fine to reheat. Just drizzle a little olive oil on top and reheat it in the oven or microwave.

Do I have to use homemade pesto?

No, you can just as well use your favorite pesto in this recipe. Whatever works best for you and makes your life easier is the way to go…although if you have the time my super easy 5-minutes homemade pesto is worth the small extra effort.
