01 - Pat chicken breasts dry with paper towels. Season both sides evenly with salt, pepper, paprika, and cumin, pressing the spices into the meat to adhere.
02 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add seasoned chicken breasts and cook for 5–6 minutes per side until golden brown and cooked through. Transfer to a plate and tent with foil to keep warm.
03 - Reduce heat to medium. Add chopped onion to the same skillet and sauté for 2 minutes until translucent. Add minced garlic and sliced jalapeños, cooking for another 2 minutes until fragrant and softened.
04 - Pour in chicken broth, using a wooden spoon to scrape up any browned bits from the bottom of the skillet. Let the liquid reduce slightly for about 1 minute.
05 - Stir in heavy cream and bring to a gentle simmer. Add shredded Monterey Jack cheese, whisking continuously until fully melted and the sauce is smooth and velvety. Simmer for 2–3 minutes until slightly thickened.
06 - Return chicken breasts to the skillet, spooning the creamy sauce generously over each piece. Simmer for 5 minutes to allow the flavors to meld together. Garnish with freshly chopped cilantro before serving hot.
