Garlic Green Beans and Portobellos with Parmesan

Garlic Green Beans with Portobellos and Parmesan – four ingredients and SO healthy and delicious!
Garlic Green Beans with Portobellos and Parmesan - four ingredients and SO healthy and delicious!

This is a bit of a cheater recipe, if only because it starts with another of my much-requested recipes, Garlic Portobellos with Pecorino Romano. But it’s one of my personal favorites and I make it so often that I was bound to make a twist on it at some point.

It happened when I was planning my Christmas dinner last month and realized I had nothing green on the table. Prime Rib with a Garlic-Peppercorn Crust, Carrot Souffle and Loaded Mashed Potatoes were on the menu already, so I needed something not only bright and colorful but would also have a different texture and a slight bit of crunch. Fresh green beans are so delightfully crisp and balanced nicely with the rest of the menu. Tossing some in with my portobellos was a perfect choice (and turned out to be one of the most popular dishes at the dinner).

To make these Garlic Green Beans with Portobellos and Parmesan, you’ll simply need to cook the mushrooms over HIGH heat (always cook mushrooms on high!), blanch the green beans then toss it all together with garlic and parmesan. More detailed instructions are in the recipe but that’s the gist of it. The best part is that you can blanch the green beans ahead of time then toss them at room temperature into the hot pan; they’ll heat up in no time. Be sure to keep them crisp; I like to take them out of the boiling water after no more than two minutes.

[Tweet “Always cook mushrooms over HIGH heat. Allow them to release their water, evaporate then brown!”]

I love this dish so much that I’ve made it to keep on hand for a healthy lunch, too. It’s great at room temperature so you could bring it to work and not have to worry about refrigeration as long as you eat it the same day. To keep it healthier, use a tiny amount of vegetable oil instead of the ghee (you need vegetable oil because of the higher smoke point, don’t use olive oil when cooking at a high temperature). The flavors are wonderful – lots of garlic and salty parmesan! I know you’ll enjoy this as much as I do.

How many servings does this make? I plan on making it for 8 people- do I need to double it? Also, can this be completely done in advance and reheated in an oven?

As a side dish, you should be fine!

Tried this as a change from the dreaded green bean casserole.

I don't know what I might have done differently, but this was a horribly bland dish. I cooked down the mushrooms using canola oil on high heat for at least 8 minutes, cooked the beans for 3 whole minutes in oiling water (and they were just barely beyond raw), I added the garlic, sprinkled the cheese.

The cheese obviously added some flavor but the garlic was barely noticeable and the mushrooms had no flavor.

I shopped for ingredients at my "standard" market down the street, the name of which rhymes with Ron's, and the quality looked good. Should I have shopped elsewhere for the mushrooms?

Just really disappointed this didn't turn out more flavorful - I really expected it to given the ingredients.

Obviously my thoughts are to add more garlic and perhaps finish the mushrooms in butter?

Agree? Other suggestions?

Hi Richard! First, I'm so sorry the recipe didn't work out for you. I know what it's like to be looking forward to a dish and have it fall flat. Second, I'm not sure what the problem could have been as it sounds like you did everything correctly. I know when I've served this dish it always gets rave reviews, so it's disappointing you didn't have the same experience. More garlic and butter is never a bad thing, in my opinion! :) I'd love for you to try it again if you're up for it. By the way, I used to shop at Vons all the time! You aren't in SoCal by chance?
