Heat 1 tbsp olive oil in a large soup pot over medium heat. Add broccolini and bell pepper with a pinch of salt & pepper. Sauté for 3 minutes, then remove from the pot and set aside.
Add the remaining olive oil to the pot over medium-high heat. Sear chicken for 2-3 minutes per side until lightly browned. Remove and set aside.
Reduce heat to low-medium. Add scallion whites, red curry paste, garlic, and ginger. Sauté for 1-2 minutes until fragrant.
Add the chicken back into the pot, followed by coconut milk, bone broth, brown sugar, fish sauce, coconut aminos, and lime juice. Bring to a gentle boil for 10 minutes until the chicken is fully cooked.
Remove chicken from the pot and shred with two forks.
Add shredded chicken, cooked veggies, and instant rice noodles to the pot. Remove from heat and stir until noodles soften. (If using regular rice noodles, cook them earlier per package instructions.)
Ladle soup into bowls, top with fresh scallions, cilantro, and a squeeze of lime. Enjoy every comforting bite!
