Portabella Steaks

Steak is steak. I will acknowledge that. Obviously a portabella steak isn’t that reminiscent of an actual steak – you don’t have to let it rest, you don’t have to sear it first, and you don’t have to ask your guests how they like it cooked, because it certainly will not have a cool pink center (if it does, there is something very wrong with your mushroom and you should immediately throw it away and send the grocery store a strongly-worded email). However, there really is something about a big juicy bite of a grilled portabella mushroom that reminds me of meat. Maybe that’s because it’s been years since I’ve eaten an actual steak and I’ve forgotten what they taste like, or maybe it’s because of the supposed umami* the mushroom embodies. Regardless, this is the one thing I feel like I can throw on a grill at a barbecue that doesn’t result in people casting sympathetic glances my way as they tear into their steaks. It’s hearty and fulfilling, and won’t leave you missing actual steak at all. It also goes from grocery bag to table in under 45 minutes (including marinating time). That being my first and pretty much only criteria for weeknight dinners, it’s heavily in the rotation around here.

*Umami is supposedly the fifth taste category that the human taste buds can discern – the one that doesn’t fit neatly into the previously defined sweet/sour/salty/bitter packages. Translated simply, it means “delicious,” but the umami flavor is generally defined as meaty, robust, or savory. Umami’s discoverer, Japanese researcher Kikunae Ikeda, identified the broken down form of the amino acid glutamate (L-glutamate) as the source of the umami taste. Guess what’s super-rich in glutamate and hence, really delicious when cooked? Yep – mushrooms. This is allegedly why mushrooms are so often used as a meat substitute, and why the texture and mouthfeel of a grilled portabella is so very steaky.  I’m not sure I buy all of that, because I’m a simpleton and my reaction is more along the lines of “chomp chomp chomp, were you saying something?”

Portabella Steaks
 
Prep time
Cook time
Total time
 
Yield: 6 servings
Ingredients
  • 1 ½ lbs whole portabella mushrooms (about 6)
  • ½ cup extra virgin olive oil
  • ½ cup balsamic vinegar
  • ⅓ cup freshly squeezed lemon juice
  • 2 garlic cloves, minced
  • 2 Tbsp chopped flat leaf parsley
  • Salt and pepper to taste
Instructions
  1. Preheat the broiler or fire up your grill. Or, if you’re me, put a grill pan on your stove and coat it with an equal mixture of Pam and your own tears, because you don’t own a grill and your oven is so old that the broiler is actually a drawer underneath the stove that licks tongues of hungry flames upon your food as soon as you open it, charring it beyond recognition and causing a cringing Pavlovian response every time someone says "broil."
  2. Place the mushrooms in a large, shallow dish (either a large baking dish or rimmed baking sheet will work well) Combine the olive oil, balsamic vinegar, lemon juice, garlic, and parsley in a bowl and mix well. Pour over mushrooms and season with salt and pepper. Marinate for 30 minutes, turning once.
  3. Place the mushrooms on a grill grate (or aforementioned grill pan) or broiler pan (gill side down if grilling, gill side up if broiling) and cook for 4-6 minutes per side. The mushrooms should give off some of their natural liquid and be mostly firm to the touch. Serve hot.
