  • 2 tablespoons sliced almonds, toasted

Instructions

  • In a large nonstick skillet cook onions, covered, over low 10 to 15 minutes or until tender, stirring occasionally and adding enough of the broth, 1 to 2 tablespoons at time, as needed to prevent sticking.

  • In a large skillet cook mushrooms over medium 3 to 4 minutes, stirring occasionally and adding enough of the broth, 1 to 2 tablespoons at a time, as needed to prevent sticking.

Onions never got carmelized in the time stated. Beans were very crisp, too. Otherwise very good!

Juanita

Recipe needs a time and temp adjustment. Onions didn't carmelize in time and temp stated. Actually ate them translucent. Think the beans could take more time as well. Otherwise delicious.

Melanie

Six cups of sliced onions is 3 medium onions, and is a LOT. I used yellow onions as I didn’t have sweet onions. If I make this again I will try with sweet onions, and use less - like 4 cups sliced.

SS

Not a fan of thyme (or rosemary, or sage for that matter). Is there another herb that can be substituted?

Dow

I’m assuming the 6 cups of onions was a practical joke. I thinly sliced one Vidalia onion.

Debbie

I have to say this was really good considering I didn't have all the onions it called for(if thats correct) and added the flour and almond milk like someone commented on to make it creamy. I wanted something extra to take to thanksgiving potluck tomorrow at church that didn't have all the butter and cheesy stuff since I started wfpb about a month ago. ( work in progress). I will definitely make this again.

Joy

How many onions should I get to makes 6 cups?

Sunny

I made this recipe to go with our Christmas dinner tonight. It was a smash hit. Thx for the inspiration and keep the healthy recipes coming. Best in the New Year.

Bill Nyunt

Three medium onions

Mimo

Are six cups sliced onions correct? With only one pound beans and eight ounces mushrooms?

Janet W

Very good and easy

Marie Camuccio

I doubled the recipe and put 8 cups ( should have been 12 for doubling it!)of onions in…. Way too many!! I’m think the 6 cups for 1 lb beans is a typo?

J Carlson

Wonderful! I had time so made my onions in a crock pot.

Leigh Krauss

This green bean dish is delicious. I cooked the onions and mushrooms early in the day and then reheated, adding the rest of the ingredients and finished it just before we sat down to eat. I'll make it again!

Lydia

I made this for Thanksgiving too and it was wonderful. Only changes I made were because my fiancé is enamored by the old school Campbell's Cream of Mushroom soup green bean casserole. So, to mimic the texture of that, I added just a tablespoon of whole wheat flour to the broth and a tablespoon or so of oat milk and the effect was pretty perfect! He was sold :)

D. Lee

We made these for Thanksgiving and they were amazing!
