Hot Chili Beef & Onion Soup

This soup builds its broth from scratch by simmering braising beef in water for nearly two hours until the meat falls apart. No stock cubes, no shortcuts. The beef itself creates a rich, clean broth that becomes the canvas for a bold Korean-inspired chili and sesame flavor profile.

The technique of pulling the tender meat out of the broth and tossing it in a hot pan with chili-infused sesame oil, shredded green onions, garlic, and toasted sesame seeds is what makes this soup stand apart. That quick fry coats each piece of beef with concentrated heat and nuttiness before everything goes back into the pot. The flavors hit differently than just dumping spices into the broth.

Dark soy sauce and a touch of sugar round out the heat with salty depth and a hint of sweetness. White pepper adds a sharper, more aromatic burn than black pepper would. The finished soup is thin-bodied but intensely flavored, the kind of broth that warms you from the inside out.

Kitchen Tips

• Use a tough, collagen-rich cut like chuck or shin for the braising beef. Lean cuts won’t break down or create as flavorful a broth
• Keep the simmer very gentle. A hard boil makes the broth cloudy instead of clear
• Toast the sesame seeds in a dry pan until golden before adding. Raw sesame seeds taste flat in comparison
• The red pepper flakes are generous at 1 ½ tablespoons. Start with half and add more after tasting if you prefer less heat

Variations

• Add sliced daikon radish to the broth during the last 30 minutes of simmering for a more traditional Korean soup
• Stir in a beaten egg at the end for silky egg ribbons
• Top each bowl with kimchi and a drizzle of extra sesame oil for a fuller meal
