  • 1 18 ounce Tube of prepared polenta cut into ½ inch slices
  • 1 cup unsweetened, unflavored plant milk I used oat milk
  • 1 Tablespoon dijon mustard
  • 2 cups breadcrumbs
  • ¼ cup nutritional yeast
  • 2 teaspoons garlic power
  • 2 teaspoons onion powder
  • 1 Tablespoon Italian Seasoning
  • 2 Tablespoons Fresh parsley, chopped Optional garnish
  • 1 ½ cups Marinara sauce


  • Unwrap the polenta tube.
  • Cut the polenta into ½-inch slices.
  • Prepare two wide shallow bowls.
  • In one bowl, whisk together the plant milk and dijon mustard.
  • Combine the bread crumbs, nutritional yeast, and spices in the second bowl.
  • Dip each slice of polenta into the milk mixture bowl and then directly into the breadcrumb mixture, covering each slice of polenta with teh bread crumb mixture.
  • Transfer each breaded slice of polenta to a prepared baking sheet or an air fryer pan.


  • Preheat the oven to 400 degrees.
  • Prepare a baking sheet with parchment paper or a silicone baking mat.
  • Place the breaded slices on the baking sheet in a single layer, leaving a small space between each slice.
  • Bake for 30 minutes until crispy.
  • Remove from the oven and sprinkle with parsley.

Air Frying

  • Preheat the air fryer to 350 degrees.
  • Place breaded polenta slices in the air fryer basket or an air frying pan.
  • Cook for 15 minutes until fries are crispy.
  • Remove from the air fryer and sprinkle with parsley.

Marinara Sauce

  • Heat the marinara sauce in a small sauce pan or heat in the microwave while the crispy polenta cooks.


  • Most people suggest drying the polenta before cutting and seasoning. However, because I cook without oil, its natural stickiness and the plant milk mixture make the breading stick to the slices.
  • If you have a basket air fryer, remember that the first batch takes longer to cook than the subsequent batches.
  • Preheat the oven to 325 if batch cooking the crispy polenta in an air fryer to keep the cooked ones warm.
  • Other sauce suggestions are lemon basil dressing, mustard sauce, and vegan ranch.
  • Make it fun for the family and kids and cut animal shapes with cooking cutters for a great snack for the kids.
  • Try using cookie cutters to make bite-sized polenta bites for an appetizer or for a charcuterie board.
