I’d go as far as to say that these Hasselback parmesan mushrooms could be a vegetarian main entree because they are hearty!
Hasselback Parmesan mushrooms are elegantly styled & air-fried.
I love making Hassleback baked potatoes, but Hasselback parmesan mushrooms and onions will steal the show when plated!
These, in fact, are part of my Signature Collection of Recipes.
What’s Hasselback and my Mushroom transition.
Long ago, I cooked baked potatoes in a different way, the method is called ‘Hasselback slicing’
For those not familiar with ‘Hasselback slicing’ it’s kind of a game-changer when it comes to expanding your area for coating and filling.
In fact, it much reminds me of stuffing an artichoke because when you stuff each leave it expands, now you got it!
As, what I’ll term, ‘mushroom-a-holic’ I constantly am blending mushrooms into everything that I cook.
Meatless but meaty tasting, this fungus is perfect as an addition or stand-alone to any meatless meal!
Since I consume a lot of mushrooms, I work them into foods my family eats as well (they all eat meat!)
Hasselback parmesan mushrooms are a great plant-based entree
However, as a plant-based protein girl, I also love mushrooms just as they are even if they only yield about 3 grams of protein for an entire cup!
Add an Air fryer to recipe creation and suddenly, it’s a useful vehicle to cook food and keep it intact.
For that reason, I’ve been able to easily create elegantly-styled air-fried Hasselback Parmesan Mushrooms with caramelized onions!
Now, pull out your air fryer, cutting boards and read through the easy directions, and let’s cook!
What To Serve with Air-Fried Hasselback Parmesan Mushrooms
What would I serve these air-fried Hasselback Parmesan Mushrooms with?
Use them as a meal, a side dish to a meal, like steaks, seafood, pork, chicken, etc.
I’ll be honest when I initially sliced potatoes in this manner, it was to trick myself into feeling more full.
Also, I loved that the ingredients that I sprinkled atop were also below deck, lol, or so to speak.
Finally, I feel that the potato was cooked thoroughly without the pricking and prodding to ensure that!
So, it seems that the natural segue to Hasselback Potatoes is Hasselback Mushrooms.
Meaty & Tasty
Mushrooms and caramelized onions with parmesan cheese atop.
Mushrooms have depth in taste, and depending on how you prepare them will depend on how much taste you get out of them!
Earthy, meaty, burger-like, all ways in which one might describe the overall taste of mushrooms when properly prepared.
Personally, less is better, and air-fried is spectacular.
Tips To Know For Air-Fried Hasselback Parmesan Mushrooms
You will want to use a wider mushroom, larger in order to do this.
Little snowcap mushrooms are not big enough and you won’t have success with them.
Portobellos are amazing this way, but, they are not as tall, so they will be more wide than tall.
I prefer to use large white stuffing mushrooms that are about 2 to 2 1/2″ wide in diameter.
Perfect the air-fried mushrooms with caramelized onions
Air-fried mushrooms with caramelized onions are not hard to make, nor time-consuming but they do look elegant!
You’ll start by really cleaning your mushroom by first giving it a good shake, that gets rid of ‘dirt’ debris which is not actually dirt.
Then, give it a rinse, and pat it dry with a paper towel.
In fact, mushrooms are delicate so don’t press too hard or you will break the mushroom.
Additionally, peel your onions, I use sweet yellow.
Slice then and double what you might think you need or follow my recipe because onions shrink when cooked.
Air-fried mushrooms and onions are really a terrific combination that will truly elevate your side dish game. ‘
