Baked portobello fries are a dream. Let me explain.
1. They’re crispy on the outside.
2. They’re baked, not fried.
3. Since they’re baked and not fried, we convinced ourselves that we can eat a lot of them. I think we’re right.
4. They’re juicy inside and full of flavor — more than a fry replacement, we’re thinking chicken tender replacement — that’s how good they are.
5. We ate a lot of them. A lot.
How We Make Baked Portobello Fries
It all starts with big portobello mushrooms. We remove the stalk as well as the darker colored gills. This isn’t something we normally do, they’re completely fine to eat. In this case, though, it’s admittedly prettier in the end if you remove them.

Give the mushrooms a slice then set up a breading station. Nothing fancy here – flour, eggs and breadcrumbs.
If you’ve got some on hand, use panko breadcrumbs, they give a lighter crunch than regular breadcrumbs. With that said, we’ve baked these portobello fries with both regular breadcrumbs and panko – both are delish.

Once breaded, the fries get a little spray of cooking spray then we slide them into the oven to bake for … wait for it … 10 minutes! So quick, right?

If you’re feeling up to it, make a creamy horseradish dip to serve alongside the fries. Just mix mayo, a little lemon juice and prepared horseradish. You can make it as spicy as you like.
Don’t feel like making your own sauce? Ketchup is perfectly delicious, too!
- 2 portobello mushrooms
- 1/2 cup all purpose flour
- 2 eggs, lightly beaten
- 1 cup panko breadcrumbs
- 1 1/2 teaspoons steak seasoning
- non-stick cooking spray
- Heat oven to 425 degrees F. Line a baking sheet with aluminum foil or parchment paper.
- Remove the stalks from each mushroom then use a spoon to scrape out any dark gills from the underneath of each mushroom and discard. Cut mushrooms into 1/4-inch slices.

- Set up a breading station by adding the flour, eggs and breadcrumbs to three separate shallow dishes. Add the steak seasoning to the breadcrumbs and stir.
- Dredge each mushroom slice into the flour then add to the egg to coat and finally into the breadcrumbs so that each slice is well breaded.
- Arrange breaded mushrooms onto baking sheet then lightly spray with non-stick cooking spray. Bake 8-10 minutes, turning once during cooking, until golden brown and crispy.

- Serve portobello fries with ketchup or your favorite flavored mayo.

Oh my! These sound delicious!
I can’t believe this just uses 6 ingredients! And so super-perfect for something quick…especially now, since the heat here has made it impossible for me to go anywhere near the kitchen!
What an amazing idea!
Love this! We get 5lbs of Mushrooms at Costco’s every week, that’s how much we Love Shrooms! I like the Horseradish Mayo Idea… Brilliant!
Have a Great Weekend.
I love those mushroom fries! So creative and delicious.
Looks. So. Good. O.M.G.
Oh my gosh! I love this. Why oh why have I never made these?
Hope you guys are dong well!
Yum. I just made zucchini this way and it was excellent. I’ll have to try the mushrooms!!
I first made these a few days after you guys had posted the link on Facebook. It was just TOO simple not to try. I loved how easy and delicious it was — perfect for an appetizer or snack. I loved dipping them in Sriracha and mayo mix as well.
So glad you enjoyed them
We love those fries!
I just discovered you guys on the net while looking for a creamy veggie soup recipe.
I couldn’t stop going from one recipe to the next as most of your ideas hit all the cords of my taste. These baked portobello fries are simply an amazing idea.
I didn’t really cook for the past 10 years for my late husband was a chef. I now have to take over the job of cooking for my 6 year old son. I’m very curious to find out if these “fries” will appeal to him as he doesn’t like mushrooms at all. Unlike him, I love mushrooms so I’m not worried about wasting time on trying your recipe.
I love these. I do my chicken the same way. I add a little parmesan to the panko and put the seasoning in the eggs. Comes out great every time.
Love that you add the parmesan!
