Crockpot Onion And Flanken Soup Meat – Yields 8 Servings – Freezer Friendly

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



  • 12 onions sliced into half-moons
  • 1 Tablespoon kosher salt
  • 1/2 teaspoon freshly ground black pepper
  • 1/4 cup canola oil
  • 2 pounds bone-in flanken
  • 4 cups beef, chicken, or vegetable broth
  • 3/4 cup red wine
  • 1/4 cup red miso paste



  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 4-5 hours, until onions are golden brown.
  3. Add broth, wine, and miso paste; stir to combine. Cook on high for an additional hour.


Cook’s 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.
