Ingredients

  • 5 large portobello mushrooms
  • ¾ cup unsweetened unflavored plant milk
  • 3 Tablespoons Dijon Mustard
  • 1 cup breadcrumbs gluten-free Panko, or regular bread crumbs
  • ½ cup nutritional yeast

Stone-Ground Mustard Dip

  • ½ cup raw cashews or substitute silken tofu or white beans for a nut-free option
  • ¼ cup stone-ground dijon mustard
  • ½ cup water

Instructions

Prepping the Mushrooms/Dipping Bowls

  • Because portobello mushrooms are delicate,  be careful as you remove the stem.
  • Wash the outside of the mushroom cap using a small amount of water, gently washing away any dirt. Do not submerge the mushrooms to wash them.
  • Instead, use the water to help remove the dirt and carefully use a paper towel or cloth towel to dry off the mushroom.
  • Once cleaned, I cut the portobello mushrooms, lengthwise about ½ an inch wide, so they are all approximately the same size. As a result, the portobello fries will cook evenly. 
  • Now, assemble 2 wide bowls (to accommodate the size/length of the longest portobello fry; sizes may vary), and whisk plant milk and dijon mustard in one bowl. In the other bowl, combine the bread crumbs and nutritional yeast.

Baking

  • Preheat the oven to 400.
  • Dip each portobello stick into the plant milk mixture, and then dip it in the breadcrumb mixture, one at a time, until all mushrooms are covered in breadcrumbs.
  • Lay each fry on a baking sheet, separated from each other, on a silicone mat or parchment paper.
  • Cook at 400 for 20 minutes, flipping each fry over after cooking for 10 minutes. 
  • I use my Copper Chef Crisper and air-fryer in the oven to avoid having to flip the portobello fries at the halfway point. 

Air Fryer

  • Preheat to 400.
  • Dip each portobello stick into the plant milk mixture, and then dip it in the breadcrumbs mixture, one at a time, until all zucchini is covered in breadcrumbs.
  • Lay each fry in the base of the air-fry plan, separated from each other.
  • Cook at 400 for 9 minutes.
  • Remove each batch and repeat this process until all the portobello fries are cooked. 

Stone Ground Mustard Dip

  • Add all ingredients to a high-speed blender.
  • Blend on high until smooth.
  • Cover and refrigerate until ready to serve.

Notes

    • Cut the portobello mushrooms equally so they cook at the same rate.
    • Preheat the oven or the air fryer before adding the portobello fries.
    • Instead of using large portobello mushrooms, try smaller mushrooms in this air fryer mushroom recipe.
    • When batch cooking in the air fryer, it's best to preheat an oven to 325 degrees to keep the cooked fries warm while cooking the other batches.
    • For a gluten-free option, use gluten-free breadcrumbs.
    • To reheat portobello fries in the oven, preheat the oven to 350 degrees. Reheat for 10 minutes.
    • For reheating in the air fryer, preheat the air fryer to 350 degrees and cook for 5 minutes.
    • I do not recommend reheating in the microwave; the fries get soggy.
