One-pot black garlic tonkotsu ramen in a bowl with crispy seared chicken thigh, flash-wilted A-choy, green onions, and black garlic oil

One-Pot Black Garlic Tonkotsu Ramen with Crispy Chicken

Prep Time: 5 minutes

Cook Time: 12 minutes

Servings: 1

If you think instant ramen can’t match the depth and richness of a local ramen shop, this one-pot black garlic ramen hack will completely change your mind.

By pan-searing a skin-on chicken thigh directly in your cooking pot, you render out liquid gold. Deglazing those caramelized pan drippings with water builds a deeply flavorful chicken-infused tonkotsu broth from scratch. Paired with springy bar noodles, tender-crisp Taiwanese A-Choy, and aromatic black garlic oil (Mayu), you get a restaurant-quality bowl in under 15 minutes—with only one pot to clean.

Why This One-Pot Method Works

  1. Fond is Flavor: Searing chicken skin directly in the pot creates a layer of caramelized proteins at the bottom (called fond). Scraped up during deglazing, it boosts the instant tonkotsu soup powder into a velvety broth.
  2. Zero Wasted Fat: The rendered chicken fat stays in the pot, adding natural body, gloss, and richness to the soup without needing extra butter or heavy oils.
  3. Flash-Wilted Greens: Adding Taiwanese A-Choy during the final 15 seconds of boiling preserves its vibrant green color and crisp bite, perfectly balancing the rich garlic broth.

Ingredients & Substitutions

For the Chicken & Base:

  • 1 Skin-on, bone-in chicken thigh (deboned, skin intact)
  • 1 tsp Cooking oil (neutral oil like canola or vegetable)
  • Pinch of Kosher salt & freshly cracked black pepper
  • ½ tsp Soy sauce (for glazing the pan drippings)

For the Ramen & Broth:

Toppings & Finish:

  • 50g Taiwanese A-Choy (washed and cut into 2-inch pieces)
    • Substitution: Romaine lettuce, Baby Bok Choy, or Yu Choy work great.
  • 1 tbsp Fresh green onions (finely chopped)
  • ½ tsp Toasted white sesame seeds

Step-by-Step Instructions

Step 1: Prep the Veggies & Debone Chicken

  • Prep Veggies: Cut off the root stem of the Taiwanese A-Choy and cut leaves into 2-inch pieces. Finely slice the green onions for garnish and set aside.
  • Debone Thigh: Place the chicken thigh bone-side up on your board. Run a sharp knife along both sides of the bone, scrape the meat down, and slice underneath the joint to remove the bone cleanly while keeping the skin 100% intact.

Step 2: Crisp, Season & Sear the Chicken

  • Heat 1 tsp cooking oil in your pot over medium heat.
  • Place the chicken thigh skin-side down in the pot.
  • Immediately season the exposed flesh side directly in the pot with a pinch of salt and black pepper.
  • Sear undisturbed skin-side down for 5 to 6 minutes until deep golden and crackling.
  • Flip flesh-side down and cook for another 5 to 6 minutes until the internal temperature reaches 165°F (74°C).
  • In the final minute, drizzle ½ tsp soy sauce into the rendered drippings around the chicken to caramelize the fond.
  • Transfer the chicken to a cutting board to rest for 2 minutes. (Leave all fat and browned bits in the pot!)

Step 3: Deglaze & Boil the Broth

  • Pour 450 ml of water directly into the hot pot, using a wooden spoon to scrape up all caramelized chicken bits from the bottom.
  • Stir in the Tonkotsu soup powder until dissolved, then bring to a rolling boil over medium-high heat.
  • Add the bundle of Nissin bar noodles into the boiling broth. Cook for 1 minute.

Step 4: Flash-Wilt Greens & Blend Aromatics

  • Add the A-Choy into the boiling pot alongside the noodles for the final 15–20 seconds to flash-wilt.
  • Turn OFF the heat completely.
  • Stir in the Black Garlic Oil (Mayu) packet right before serving.

Pro Tip: Always add Mayu off-heat! Extreme boiling temperatures dull and burn off the delicate toasted garlic compounds.

Step 5: Assemble & Serve

  • Slice the rested crispy chicken thigh into clean, even strips.
  • Pour the noodles, rich black garlic broth, and wilted A-Choy into a deep ramen bowl.
  • Arrange the sliced chicken thigh on top and finish with chopped green onions and toasted white sesame seeds. Serve immediately!

Chef's Tips for Success

  • Dry Skin Equals Maximum Crunch: Pat the chicken skin thoroughly dry with a paper towel before placing it in the pan.
  • Save the Bones: Don't toss out the trimmed chicken thigh bone! Save it in a freezer bag to build homemade bone broth later.
  • Control the Salt: The pan drippings and soup powder are both naturally savory. Stick to a light pinch of salt on the chicken flesh side.
