1. Start by patting the chicken breasts dry with paper towels. This helps them brown beautifully. Season both sides with salt, pepper, smoked paprika, and cumin.
2. Heat the olive oil in a large skillet over medium-high heat. When the oil shimmers, add the chicken breasts. Cook for about 5-6 minutes on each side until golden brown and cooked through (internal temperature should reach 165°F). Remove the chicken and set aside.
3. In the same skillet, add the chopped onions and jalapenos. Sauté for about 4 minutes until the onions soften and the jalapenos release their aroma. Mama Lou always said, “Let the kitchen smell like sunshine and spice”—this step is where that magic starts.
4. Add the minced garlic and cook for another minute, stirring constantly to avoid burning.
5. Pour in the chicken broth, scraping the bottom of the pan to lift all those flavorful browned bits. Let it simmer for 3-4 minutes to reduce slightly.
6. Lower the heat and stir in the sour cream or Greek yogurt. Mix gently until you have a creamy sauce. If it feels too thick, add a splash more broth until you reach your desired consistency.
7. Return the chicken to the skillet, spooning the sauce over the top. Cover and simmer on low for another 5 minutes so the flavors meld together and the chicken stays juicy.
8. Garnish with fresh cilantro before serving. This final touch adds a bright, fresh note that I always look forward to—just like Mama Lou’s kitchen window herb garden.

One little tip from my sister Ouma: always let the chicken rest for a few minutes before cutting into it. It locks in the juices and keeps every bite tender and flavorful.
