Crockpot Onion and Flanken Soup

Who doesn’t love a big bowl of onion soup? However, making it can be time-consuming, as you have to sauté the onions for a long time while stirring them. This recipe allows you to skip the sautéing, as your crock pot does all the work for you.

Ingredients (8)

Main ingredients

Start Cooking

Prepare the Soup

  1. Combine onions, salt, pepper, and oil in a crockpot; stir to combine.

  2. Add flanken to the crockpot; cover with onion mixture. Cover; cook on high for four to five hours, until onions are golden brown.

  3. Add broth, wine, and miso paste; stir to combine. Cook on high for an additional hour.

     

Tip:

Miso paste is a paste made from fermented bean curd. Used primarily in Japanese cooking, it adds umami, depth of flavor, to the dishes. Miso paste is available in a variety of colors; the darker the color, the stronger the flavor. I use them interchangeably.

    Hi! Yes, you could make this for Shabbos day. Put it up right before Shabbos and add an extra cup of water :) You could use boneless flanken.

    I was just wondering the same thing. Can I prepare the crock pot before Shabbos and have the soup for lunch?

    Hi, I only have a smaller crock pot. Will the onions need more time to cook down? Thanks

    As long as you cook it for enough time, it should be fine.

    1) can this be made without crockpot? 2) how do you serve it (what do you do with the bones)?

    Anything that can be made in a crock pot can be made regularly in a pot on the stove. The difference is that you put your food in the crock pot and let it do the "work". In a regular pot you have to stir and watch that there is enough water, brown and stir onions, etc. I imagine that you can serve the soup with or without the bones. It's up to you.

    Cabernet Sauvignon

    Does the red wine have to be dry wine? Or can I substitute with a semi-sweet wine?

    You can leave it out but I would substitute it with some 1-2 tablespoons of soy sauce.
