Heat the olive oil in a large Dutch oven or pot over medium heat. Add the chicken and season with salt and pepper.
1 ½ pounds chicken breast, salt + black pepper, 1 ½ tablespoons olive oil
Cook for 3–4 minutes, until golden. Remove and set aside. In the same pot, add the garlic, bell pepper, and onion.
3 cloves garlic, 1 red bell pepper, 1 cup onion
Sauté for 3–4 minutes, stirring now and then, until softened. Stir in the red curry paste and grated ginger.
1 tablespoon freshly grated ginger, 2 tablespoons red curry paste
Cook for 1 minute, just until fragrant. Pour in the chicken broth and coconut milk. Use a wooden spoon to scrape up any browned bits from the bottom. Return the cooked chicken to the pot.
1 can unsweetened coconut milk, 6 cups low-sodium chicken broth
Bring everything to a boil, then lower the heat and simmer for about 10 minutes. Add the rice noodles, fish sauce, and agave or brown sugar. Simmer for 5 minutes, or until the noodles are soft.
4 ounces thin rice noodles, 1 tablespoon agave syrup, 1 tablespoon fish sauce
Turn off the heat and stir in the green onions, cilantro, basil, and lime juice. Taste and adjust with salt and pepper if needed. Serve hot and enjoy.
