📕 What are Portobello Mushrooms?
Portobello Mushrooms are large Mushrooms with a wide brown cap.
They are the grown version of the crimini and ultimately of the common button mushroom.
That means all 3 mushrooms are from the same variety, just one is grown out and the others are baby or medium aged mushrooms.
At the same time flavors are similar, however, the older the mushroom gets the more intensive the taste.
So, button mushrooms taste rather plain while their big brothers have a more complex flavor to them when sauteed, stir-fried, grilled or roasted.
🆚 Common Button Mushroom VS Cremini Mushroom VS Portobello Mushroom
Common Button Mushroom
Most common mushroom in the world, the button mushroom, is white. That's the baby version of the Portobello mushroom
Cremini Mushroom
The Cremini Mushroom is a button mushroom that has turned older, having now a brown cap
Portobello Mushroom
The Portobello mushroom is a grown-up version of the button and cremini mushroom
🍄 Ingredients
For this particular sauteed portobello mushroom side dish, you won't need that many ingredients.
The mushroom is going to lend the dish the flavors it needs and you certainly don't want to mask these wonderful mushrooms with anything else.
Yet, I do enjoy adding some fresh thyme sprigs to the portobello mushrooms while they sautee.
You will enjoy the flavors! Thyme compliments mushrooms subtly.
Garlic is another ingredient that will enhance your gorgeously cooking portobello mushrooms in the skillet.
So don't skip the garlic!
Onion is my friend here as well and shouldn't be missed.
I sauteed the portobello mushrooms with butter.
I just think it's more suitable as it works with the other ingredients.
You can use olive oil too if you want vegan sauteed portobello mushrooms.
White Wine is the surprise ingredient here.
The wine will add a nice acid touch to compliment the mushroom, thyme, butter, garlic, and onion.
Without the wine, it would just be a boring side dish.
🍴 Serving
I think the best way to enjoy this side dish is by pairing the sauteed portobello mushrooms with a meat dish.
It can be a saucy or dry meat dish, yet the saucier the better!
Serve the portobello fry with chicken, beef, veal, pork or even fish.
Here some meat meal pairing ideas:
- Beef Steak with Herb Butter
- Whole roasted Chicken with Thyme and Rosemary
- Parchment baked Salmon en Papillote
Yet, of course, you are free to serve the side dish with vegetarian fare.
I can recommend the following veg dishes:
🔪 How to make it?
To prepare the sauteed portobello mushroom, slice/cut all your ingredients before you start cooking.
Then heat up your pan and fry the onions translucent, then cook the garlic and the sliced mushrooms.
The mushrooms will lose water which is all good so they get sauteed gently until they reduce in size considerably!
Season and pour in the wine which will dissolve instantly in a hot skillet.
So make sure to stir everything after you have poured the wine.
Then add the fresh thyme sprigs.
Let the mushrooms cook so to take in the aroma of the other ingredients until you think the mushrooms are cooked, the sauce has dissolved and the taste is right.
