📅 Step-by-Step Cooking Timeline

🕠 Friday, 8:00 PM – Prep Your Broth

Step 1:

  • In the crock pot: Add pork bones, onion, garlic, ginger, and enough water to fill.
  • Optional: Add dried shiitake or a strip of kombu for bonus umami.
  • Set your slow cooker to LOW for 12 hours.

🕒 Running Time: 12h


🕗 Saturday, 8:00 AM – Start on Chashu (Pork Belly)

Step 2:

  • Wrap pork belly with kitchen string to help it hold shape.
  • Add pork belly to the crockpot (still with broth).
  • Top up water, if needed.
  • Set slow cooker to HIGH for 4 hours.

🕒 Running Time: 16h


🕓 Saturday, 12:00 PM – Strain & Finish Broth

Step 3:

  • Skim off scum from the broth.
  • Carefully strain into a large pot and set aside.
  • Discard bones and aromatics.

🕛 Saturday, 12:00 PM – Braise the Chashu

  • In the emptied crock pot, add:
    • ¾ cup of reserved broth
    • Soy sauce, mirin, and sake
  • Gently add pork belly. Cover with foil and press down to keep the meat submerged.
  • Set slow cooker to HIGH for 2½ hours.

🕒 Running Time: 18.5h


🕐 Saturday, 2:30 PM – Chill Chashu & Prep Toppings

Step 4:

  • Remove pork belly, place on a plate, cover, and chill until ready to serve. (You can freeze until firm if slicing soon.)
  • Reserve the chashu sauce for serving.
  • Soft-boil eggs: 7 minutes in boiling water + splash of vinegar, then transfer to an ice bath.
  • Optional: Marinate eggs (we prefer them unseasoned here).

🕕 Saturday, 6:30 PM – It’s Dinner Time!

Step 5:

  • Cook ramen noodles per package directions.
  • Reheat broth to a rolling boil.
  • Slice pork belly (remove string first) using a sharp knife.

To serve each bowl:

  • 2–3 tbsp chashu sauce
  • A ladle of hot broth
  • Noodles, pork belly, egg, and scallions
  • Add menma and nori, if desired.

Cue the “oohs” and “mmms.” You earned this.


🧠 Tips & Variations:

  • Too rich? Add a squeeze of citrus—yuzu works beautifully.
  • Want richer? Grate in a touch of butter before serving.
  • Add heat: Toss in chili flakes or fresh chilies when reheating broth.
  • Short on time? Use a miso broth and skip the overnight simmer.
  • Add veggies: Sweet corn kernels are a great match.

🧊 Storage & Make Ahead:

  • Broth freezes beautifully. Let it cool, then portion into jars or freezer bags.
  • Soft-boiled eggs can be made a day ahead.
  • Pork belly keeps well in the fridge for 2–3 days or freeze for future use.

📝 A Little Note from My Kitchen:

What started as a birthday dish for my sister-in-law has now become part of our growing Japanese-inspired recipe series.

This recipe is heavily adapted from Just One Cookbook’s Shoyu Ramen. I reworked the method to match our flavor preferences and weekend schedule—slow-simmered overnight in a crock pot for maximum flavor with minimum fuss.
