Ingredients

• 1 pound Boneless pork belly
• 3 pounds Pork bones (neck or femur)
• 6 Garlic cloves
• 2 inches Ginger
• 6 Green onions
• 0.5 cup Soy sauce (or tamari for gluten-free)
• 2 tablespoons White miso paste
• 2 scoops Unflavored collagen powder
• 1 tablespoon Coconut aminos
• 1 tablespoon Avocado oil
• 2 packs Low-carb shirataki noodles (konjac noodles)
• 2 Eggs
• 1 teaspoon Sesame oil
• 1 sheet Kombu (dried kelp)
• 0.5 teaspoon Salt
• 0.25 teaspoon Ground black pepper
• 2 Nori (seaweed sheets)

Directions

Step 1

Start by preparing the pork belly. Roll the pork belly into a tight cylinder and secure it with kitchen twine. Sear the pork belly in a hot pan with avocado oil until golden brown on all sides. Set it aside.

Step 2

In a large stockpot, combine the pork bones, seared pork belly, garlic, ginger, and green onions. Cover with water and bring to a boil. Skim off any foam impurities that rise to the surface.

Step 3

Lower the heat to a simmer and add kombu. Simmer the broth for 6-8 hours, partially uncovered, to extract all the flavor from the pork bones and develop a creamy texture. Skim occasionally if needed.

Step 4

While the broth simmers, prepare soft-boiled eggs. Place eggs in boiling water for 6-7 minutes, then transfer them to an ice bath to stop cooking. Peel and marinate eggs in a mixture of soy sauce, coconut aminos, and 1/4 cup of water for at least 1 hour.

Step 5

Remove the pork belly from the stockpot after 2-3 hours of cooking. Let it cool slightly, then slice into thin rounds. Return the bones to the pot and continue simmering.

Step 6

Strain the broth through a fine-mesh sieve or cheesecloth into a clean pot. Discard solid ingredients. Season the broth with soy sauce, white miso paste, sesame oil, salt, and black pepper. Whisk in the unflavored collagen powder for added richness and thickness.

Step 7

Prepare the shirataki noodles according to the package instructions. Typically, this involves rinsing them well and boiling for 1-2 minutes.

Step 8

Assemble the ramen bowls. Place a serving of shirataki noodles in each bowl. Pour the hot broth over the noodles. Top with slices of pork belly, halved marinated eggs, and chopped green onions.

Step 9

Garnish with nori sheets and a drizzle of sesame oil. Serve immediately and enjoy your keto-friendly Tonkotsu Ramen!
