Ingredients You'll Need

  • For the Sauce:

    • 2 tablespoon Gochujang - Korean chili paste for warmth.
    • 2 tablespoon Dark Soy Sauce - delivers deep color and flavor.
    • 2 tablespoon Rice Vinegar - adds brightness and tang.
    • 1 tablespoon Light Brown Sugar, packed - rounds out flavors with sweetness.
    • 1 tablespoon Garlic-ginger Paste - brings aromatic zing to the sauce.
    • 1 tablespoon Tomato Paste - intensifies savoriness.
    • 3.5 oz Low-sodium Beef Stock - infuses rich flavor into the dish.
  • For the Beef:
    • 14 oz Ox Cheek - the star protein, tender and flavorful.
  • For the Noodles:
    • 4 pouches Ready-to-use Udon Noodles - quick-cooking and chewy.
  • For Garnish:
    • 1-2 tablespoon Fresh Coriander, chopped - brightens the dish.
    • 1 tablespoon Black Sesame Seeds - for crunch and visual appeal.
  • To Taste:
    • Kosher Salt & Black Pepper - to enhance flavors.

When selecting your ingredients, opt for fresh produce and high-quality beef for the best flavor. If you can't find ox cheek, feel free to substitute with oxtail, short ribs, or chuck roast for equally delicious results.

Ingredient Spotlight

The star of this dish is definitely the ox cheek. Known for its rich flavor and tenderness, it becomes melt-in-your-mouth delicious as it cooks slowly in the sauce. This cut of meat brings a deep, savory quality that elevates the entire dish. If ox cheek isn't available, consider using oxtail or chuck roast for a similar taste and texture.

Step-by-Step Instructions

Preparing the Sauce

  1. In your slow cooker, combine the finely diced onion, gochujang, dark soy sauce, rice vinegar, light brown sugar, garlic-ginger paste, tomato paste, and low-sodium beef stock. Stir well to create a cohesive sauce base.
  2. Make sure the ingredients are evenly mixed; the sauce should be fragrant and rich in color.
  3. Set the slow cooker on low heat. This will allow the flavors to meld beautifully over time, filling your kitchen with an irresistible aroma.

Cooking the Beef

  1. Take the 14 oz of ox cheek and place it into the slow cooker, ensuring it's submerged in the sauce.
  2. Cover the slow cooker with its lid and cook on low for 8 hours, or until the beef is tender and easily pulls apart with a fork. The meat will become soft and custardy, soaking up all the delicious sauce.
  3. Pro Tip: If you're short on time, you can cook on high for about 4-5 hours, but I recommend low for the best tenderness.

Cooking the Noodles

  1. About 15 minutes before you are ready to serve, cook the ready-to-use udon noodles according to the package instructions. This usually takes around 5-8 minutes.
  2. Once cooked, drain the noodles and rinse them under cold water to stop the cooking process and prevent sticking.

Serving the Dish

  1. In a serving bowl, place a generous portion of the udon noodles as your base.
  2. Spoon the tender beef and sauce generously over the noodles, allowing the sauce to soak into every bite.
  3. Garnish with freshly chopped coriander and a sprinkle of black sesame seeds for added flavor and crunch.
  4. Finally, season with kosher salt and black pepper to taste, adding that extra layer of flavor before serving.

Variations

  • For a spicy kick, add sliced jalapeños or extra gochujang to the sauce.
  • Swap udon noodles for rice noodles or zoodles for a gluten-free option.
  • Add seasonal vegetables like bok choy or shiitake mushrooms during the last hour of cooking for added nutrition.
  • Try using shredded beef or pork for a different twist on the classic recipe.

Serving and Storage Tips

Serving

To serve, plate the udon noodles first, then generously layer the tender beef and sauce on top. Enjoy with a sprinkle of fresh coriander and black sesame seeds for an added touch. Pair with a side of steamed vegetables or a light salad for a complete meal.

Storage

Store any leftovers in an airtight container in the fridge for up to 3 days. For longer storage, freeze the beef and sauce separately from the noodles for up to a month. Reheat gently on the stove or in the microwave, adding a splash of beef stock to maintain moisture.

Common Mistakes

  • Not browning the beef before adding it to the slow cooker can result in less flavor. Always sear the beef for a few minutes to enhance its taste.
  • Overcooking the noodles can make them mushy. Follow package instructions closely and rinse them to prevent sticking.
  • Skipping the seasoning step at the end can dull the flavors. Always taste and adjust with salt and pepper before serving.

Helpful Notes

  • For a richer flavor, consider adding a splash of sesame oil to the sauce.
  • If you prefer a thicker sauce, mix 1 tablespoon of cornstarch with water and stir it in during the last 30 minutes of cooking.
  • Add a handful of spinach or kale in the last few minutes of cooking for a nutrient boost.
  • For a dairy-free option, ensure your beef stock is free from any dairy ingredients.
