This vegan Portobello Mushroom and Broccoli Stir Fry is a 30-minute meal that is both satisfying and also customizable with your own favorite veggies. Great served over brown rice or quinoa! (Gluten-free & oil-free.)

An Asian-style take-out dish made easy (and healthier!) right at home.
This broccoli mushroom stir-fry is only 9 ingredients and pleasantly satisfying. We like to serve it over warm brown rice or quinoa.
I find Asian take-out dishes are often weighed down by a lot of oil, so I opted for an oil-free stir-fry method for this recipe.
Simply substitute vegetable broth or water to sauté. Light and healthy, yet delicious!

Ingredients for Stir-Fry
For this recipe you will need a large skillet or wok and these ingredients:
- Portobello mushroom: Portobellos are a great meat substitute because they have such a deliciously tender texture. However you can substitute other mushrooms such as cremini, white button, shiitake mushrooms, etc.
- Fresh broccoli florets
- Onion: I use yellow onion or white onion, but red onion will work too.
- Red bell pepper: Or other color such as yellow bell pepper or orange bell pepper.
- Vegetable broth
- Tamari: Or substitute soy sauce, but I use tamari for gluten-free.
- Hoisin sauce: Be sure to use one you enjoy. I use San-J brand for gluten-free.
- Garlic cloves
- Fresh ginger
- Cornstarch or arrowroot: This is used to thicken the sauce.
I keep this recipe oil-free, however you can also stir-fry your veggies with a tablespoon of toasted sesame oil for more flavor if desired.

Customize
Change up this recipe with your own favorite vegetables to taste, or whatever is in season:
- Asparagus
- Zucchini
- Green onion (scallion)
- Snow peas or sugar snap peas
- Green beans
- Green cabbage, savoy cabbage, or napa cabbage
- Bok choy
- Carrots
You can also add more protein and flavor with tofu, tempeh, or your favorite vegan beef or chicken strips.

Serving
Grains: Either serve this dish as is, or over a bed of cooked brown rice, quinoa, or noodles.
Garnish: I like to top my bowl with sesame seeds before serving. You can also add red pepper flakes for a little spice.
If you have leftover hoisin sauce, it is also great in this Vegetable Lo Mein.

I used this recipe mainly as it was however, didn't have hoisin on hand, so I subbed soy sauce, sugar, sesame oil and siracha. Wow! It was a fantastic little meal. I'm just getting my feet wet in the kitchen and discovering I'm in love with cooking! Thank you for a fantastic Asian inspiration!!

This looks like another fantastic recipe! Very similar to the broccoli with Asian garlic sauce, which I love and make often. I'll have to find some hoisin sauce.
