Mushroom Leek Onion Kugel

This kugel is perfect for Rosh Hashana, when we have a tradition to eat leeks as one of the simanim: she’yi’korsu so’nay’nu, may our enemies be cut down. 

It’s a fresh and different side dish, bursting with flavor.  It’s easy to prepare and low fat/healthy.  This kugel will be enjoyed by all. 

Mushroom Leek Onion Kugel

Preheat the oven to 350*. 

In a large sauté pan, heat some oil over medium heat (I use light-tasting olive oil).  To the hot oil, add 1 large onion, sliced, and 4 leeks, sliced (use the white and light green parts only).  Add 2 frozen garlic cubes and 2 frozen parsley cubes.  Sauté for about 10 minutes, over medium heat, stirring often. 

To the pan, add 2 boxes (8 oz. each box) white button mushrooms, sliced. 

Season the vegetables with 1 1/2 Tbsp. m.s.g.-free onion soup mix, black pepper to taste, and 1 1/2 Tbsp. brown sugar

Continue to sauté for about 10-15 more minutes, stirring as necessary.

Shut the flame and transfer the vegetable mixture to a large mixing bowl, using a spatula to scrape all the flavors out of the frypan into the bowl.

To the bowl, add: 2 Tbsp. flour (I use white whole wheat), 2 Tbsp. oil, and 2 eggs lightly beaten.  Mix all ingredients together.

Transfer the mixture to a 9” round foil pan (or oven-to-tableware dish of your choice).  Bake, uncovered, on 350* for about 45-60 minutes, till kugel is set and browned. 

Happy cooking, b’tay’avon and enjoy!

Wishing you and yours a shana tova u’metuka – a year that is always good and only sweet.

    Can you freeze it?

      A number of people have reached out to me with the same question… I would be hesitant to freeze this kugel, as the mushrooms may not defrost well and might be very soggy and mushy.
      As it’s not so time consuming, it can easily be made erev Yom Tov.
