Combine the rice, water, and 1 teaspoon of the olive oil in a medium saucepan with a lid. Bring to a boil, cover, and reduce to a simmer. Simmer for 20 minutes (or check the time listed on the package of your rice).
Uncover and fluff with a fork. Add the garlic, scallions, and lime zest and stir to combine. Let cool for 1 minute, then add the remaining 2 teaspoons of olive oil, ¼ teaspoon salt, lime juice, cilantro, and red pepper flakes or jalapeño, if using. Stir to combine and season to taste.
