Marinate chicken pieces with curry powder, onion powder, and salt for at least 15 minutes.
In a large pot over medium heat, sauté sliced onion, chopped garlic, and smashed lemongrass until fragrant, about 3-4 minutes.
Add red curry paste and paprika, stirring for 1 minute until aromatic.
Add marinated chicken to the pot and cook briefly, about 5 minutes, stirring to coat with aromatics.
Add potato chunks, carrot chunks, bay leaves, sugar, chicken bouillon, water, and chicken broth to the pot.
Bring mixture to a boil, then reduce heat and simmer for 30-40 minutes until chicken and vegetables are tender.
Remove from heat and stir in coconut cream before serving.
Serve hot with steamed rice or baguette slices.
