Cheesy Portobello Fries with Spicy Ketchup

Portobello Fries with Spicy Ketchup

You know it’s a successful recipe shoot when you wind up with Panko on your camera and ketchup in your hair. Welcome to my average Saturday.

These Cheesy Portobello Fries were barely out of the boiling oil before I snatched one up to taste, plunging it into a kicked up version of ketchup before crunching into my first bite. I balanced the tray of hot, crispy fries in one hand while holding the ketchup and my camera in the other, and then made a beeline for my windowsill. I sampled “just one more” before setting up the above shot.

Long story short: 15 minutes passed and I found myself scrambling to style a photo-worthy portobello pile with all that remained of the deep-fried carnage. I thought I’d learned my lesson after the Homemade Barbecue Potato Chips. Photograph first, eat second. But somewhere between the 6 feet that separates my kitchen from my photo “studio” (and by “studio,” I mean dining room table) I must’ve mixed up the order.

Panko breadcrumbs are the real secret to the crispiest crunch when frying. Toss them with shredded Parmesan and fresh herbs and you have the ultimate breadcrumb mix to stick to seafood, poultry, vegetables and apparently Nikon cameras, which become innocent bystanders when trapped between hot portobello fries and my appetite.

Cheesy Portobello Fries with Spicy Ketchup

Yield: 4 servings

Prep Time: 25 min

Cook Time: 10 min


For the portobello fries:

4 large portobellos
2 cups Panko breadcrumbs, lightly crushed
1½ teaspoons dried oregano
2 Tablespoons chopped flat-leaf parsley
½ cup shredded Parmesan
3/4 cup flour
3 large eggs
Vegetable oil, for frying

For the spicy ketchup:

2 teaspoons olive oil
1 clove garlic, minced
3/4 cup ketchup
1 Tablespoon crushed red pepper flakes, or to taste
2 Tablespoons hot sauce, or to taste


Use a damp towel to clean off the tops of the portobello mushrooms, and then remove the stem and use a spoon to scrape out the gills.

Slice the portobellos into ½-inch wide strips.

Combine the Panko breadcrumbs, oregano, parsley and Parmesan in a small bowl. Place the flour in a second small bowl, and then lightly beat together the eggs in a third small bowl.

Bread each mushroom strip by coating it in the flour, then the eggs, and then the breadcrumbs. Set the breaded portobellos aside.

Prepare the spicy ketchup by setting a small saucepan over medium heat. Add the oil, then the garlic, and saute until golden. Add the ketchup, crushed red pepper flakes and hot sauce, stirring to combine. Cook 2 to 3 minutes until warm, then transfer to a serving bowl and set aside.

Heat 2 to 3 inches of vegetable oil in a large heavy-bottom pot over medium heat until it reaches 365ºF.

Working in small batches, fry the portobellos until golden brown, turning occasionally, for 1 to 2 minutes, or until golden brown. Transfer the portobello fries to a paper towel-lined plate and immediately season with salt. Return the oil to 365ºF between each batch and repeat frying process with remaining portobellos.

Serve the portobello fries warm with the spicy ketchup.

Kelly's Notes:

Ketchup is considered a dry ingredient when it comes to measuring because it can be leveled off, so make sure you use a dry measuring cup.

You can easily adjust the spiciness of the ketchup to your personal taste by adding more or less crushed red pepper flakes and hot sauce.

    Your pictures are stunning! I don’t even LIKE mushrooms but would probably warf these down because they look so stinkin’ yummy!

    I would probably use zucchini, since mushrooms have never been friends of mine.

    These sound wonderful. I was just wondering if they could be baked in the oven, instead of frying? Since the mushrooms thrmselves are quite low calorie, I could eat them more often without feeling too guilty:)

    Oh. My. God. These look amazing. I love that they are coated in panko. Panko is one of my favorite things to use in the kitchen because it helps make things so crispy. I can’t wait to try these.
