Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Season the chicken breast with half of the sea salt, black pepper, and smoked paprika, then roast for 20-25 minutes until the internal temperature reaches 165°F.
While the chicken roasts, place the tomato puree, red bell pepper, and red onion in a blender and process until completely smooth.
Heat the olive oil in a medium pot over medium heat, pour in the blended tomato mixture, and cook for 5-7 minutes until the sauce thickens and turns a deep red.
Rinse the basmati rice thoroughly and add it to the pot along with the water, dried thyme, and the remaining salt, pepper, and paprika.
Bring the mixture to a boil, then reduce the heat to low, cover tightly, and simmer for 15-18 minutes until the liquid is fully absorbed.
Remove the pot from the heat and let the rice sit covered for 5 minutes before fluffing with a fork.
Slice the roasted chicken breast and serve it over the warm, fragrant Jollof rice.
