Directions
Pat the chicken breasts dry and season generously on both sides with salt and pepper.
Heat the olive oil in a large skillet over medium-high heat.
Add the chicken and cook for 6-8 minutes per side, or until golden brown and cooked through (internal temperature reaches 165°F / 74°C).
Remove the chicken from the skillet and set aside on a plate.
Reduce the heat to medium.
Add the diced onion to the same skillet and sauté for 1-2 minutes until softened and fragrant.
Stir in the red pepper flakes, fresh lime juice, and chicken broth, scraping up any browned bits from the bottom of the pan.
Bring the sauce to a simmer and let it cook for 5-7 minutes, allowing it to reduce slightly.
Lower the heat and whisk in the heavy cream until smooth.
Do not let it boil after adding the cream.
Stir in the chopped cilantro, then return the cooked chicken breasts to the skillet. Spoon the creamy sauce over them to coat completely and let everything warm through for another minute before serving.
After adding the heavy cream, keep the heat low and avoid bringing the sauce to a full boil to prevent it from curdling.
