Grilled Vegan Portobello Steaks

May 19, 2011 by Keri

Grilling season is upon us! To be honest, we don’t even own a grill, but I love using my cast iron grill pan with summer vegetables to get similar texture, flavor, and markings. Of all of the gorgeous summer foods perfect for grilling, portobellos are my favorite. Because of their tender, juicy texture and mild flavor, portobello mushrooms are not only a favorite of the veg crowd, but also perfect to serve non-vegan dinner guests.

I’ve tried a few different marinade combinations, but I keep coming back to the balsamic because it really compliments the flavor of the portobello without overpowering it. I served these over romaine with a side of raw broccoli in vegan cheese sauce from Alive in 5, but I also love to serve them in a stack roasted garlic and giant tomato slices. A slice of grilled eggplant would be a great addition as well. Once you remember all the delicious grill-worthy vegetables and fruits, you won’t feel the slightest bit limited in your vegan summer grilling. So move over veggie burgers, there are more than just frozen patties coming to this grill party!

  1. What a great idea! This reminds me that we made a similar dish in a raw class recently. Marinade and dehydrate. Have to remember to try both! I’m looking forward to a sunny weekend and lots of grilled eats!

    • Keri says:

      Oh, I’ll have to look for/try a dehydrator portobello recipe too. That sounds delicious!

  2. Wow! These look amazing!

  3. I love grilled portobellos! Especially when they have been marinating in balsamic and garlic for awhile!

    • Keri says:

      It’s hard to go wrong with portobellos, but I think balsamic and garlic especially suits them!

    Yum!!! I love grilling portobellos, but we don’t have a grill, either. I am totally making this recipe when I’m at my parents’ house or our family cabin! 😀

      Ooooh, a family cabin sounds lovely! And grilled portobellos sound like perfect cabin food! I hope they turn out great! 🙂
