01 - Pat chicken breasts dry with paper towels. Season both sides with salt, pepper, paprika, and cumin, pressing spices into meat to adhere.
02 - Heat olive oil in a large skillet over medium-high heat. Add chicken breasts and cook 5–6 minutes per side until golden brown and internal temperature reaches 165°F. Remove chicken and set aside on a plate.
03 - In the same skillet, add chopped onion 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. Reduce heat to medium and let broth simmer for 1 minute to reduce slightly.
05 - Stir in heavy cream and shredded Monterey Jack cheese. Continue stirring until cheese melts completely and sauce becomes smooth and creamy. Simmer gently for 2–3 minutes until slightly thickened.
06 - Return chicken breasts to the skillet, spooning sauce generously over each piece. Simmer for 5 minutes to allow flavors to meld and chicken to heat through.
07 - Remove skillet from heat. Sprinkle chopped fresh cilantro over the top as garnish. Serve immediately with sauce spooned over each chicken breast.
