01 - Pat chicken breasts dry with paper towels. Season both sides generously with salt, black pepper, paprika, and ground cumin, pressing the spices into the meat.
02 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add chicken breasts and cook for 5–6 minutes per side until golden brown and internal temperature reaches 165°F. Transfer to a plate and cover loosely with foil.
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 chicken broth into the skillet, using a wooden spoon to scrape up any browned bits from the bottom. Let the liquid reduce slightly for about 1 minute.
05 - Stir in heavy cream and shredded Monterey Jack cheese. Continue stirring until cheese is completely melted and sauce is smooth and bubbly. Simmer gently for 2–3 minutes until slightly thickened.
06 - Return chicken breasts to the skillet, nestling them into the sauce. Spoon sauce generously over each piece. Simmer for 5 minutes to allow flavors to meld together. Garnish with fresh chopped cilantro just before serving.
