Step-by-Step Instructions
Follow these steps to cook the Tex Mex Chicken and Zucchini to juicy, flavorful perfection.
- Prep the chicken and vegetables
- Pat chicken pieces dry and season with half the chili powder, cumin, smoked paprika, salt, and pepper. Toss zucchini, bell pepper, and onion with the remaining spices and a drizzle of olive oil.
- Sear the chicken
- Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add chicken in a single layer and brown for 3–4 minutes per side until golden (it doesn’t need to be fully cooked). Remove chicken and set aside.
- Cook the vegetables
- In the same skillet, add another drizzle of oil if needed. Sauté onion until translucent, add garlic for 30 seconds, then add zucchini and bell pepper. Cook until edges are tender and just caramelized.
- Combine and simmer
- Return the chicken to the pan, squeeze in lime juice, and reduce heat to medium-low. Cover and let Tex Mex Chicken and Zucchini simmer for 6–8 minutes until chicken is cooked through and flavors meld.
- Finish and rest
- Remove from heat, stir in cilantro and optional shredded cheese, and let the Tex Mex Chicken and Zucchini rest for a few minutes so juices redistribute.
- Optional bake (with topping)
- If you want a baked finish, transfer everything to a shallow baking dish, sprinkle the streusel/crumble on top, and bake at 375°F (190°C) for 10–12 minutes until the topping is golden and cheese is bubbly.
Tips for Success
- Avoid watery zucchini: choose medium zucchinis and sauté on higher heat to evaporate excess moisture quickly.
- Even cooking for chicken: cut pieces uniform in size and don’t overcrowd the pan when searing.
- Balancing spice: start with the suggested chili powder and taste before adding more; you can always add a pinch of cayenne if you want extra heat.
- Make it ahead: this dish reheats wonderfully and flavors often deepen after a day in the fridge.
Possible Variations
- Gluten-free: Use gluten-free flour or almond flour in the streusel, and ensure any seasoning blends are certified gluten-free for a fully gluten-free Tex Mex Chicken and Zucchini.
- Vegetarian swap: replace chicken with firm tofu or chickpeas and increase spices for added depth.
- Streusel topping: try a savory cornbread-style crumble with cornmeal, shredded cheese, and scallions for a comforting twist.
- Lighter pairing: serve the Tex Mex Chicken and Zucchini over brown rice, quinoa, or alongside a fresh tomato and pasta salad—see our zucchini with pasta and tomatoes for a bright, seasonal pairing.
Storage Recommendations
- Refrigerate: Store leftovers in an airtight container for up to 3–4 days. Reheat gently on the stovetop over low heat or in a 350°F oven to preserve texture.
- Freeze: For longer storage, freeze in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Reheating tip: Add a splash of water or broth when reheating to loosen the sauce and prevent drying, especially if you used the bake-and-top method.

A: Sear the chicken quickly on high heat to lock juices, avoid overcrowding the pan, and finish cooking gently in the skillet with a splash of lime juice or broth. Resting the chicken a few minutes before serving helps keep it tender.
Q: Is this recipe suitable for a gluten-free diet?
A: Yes—swap any flour in the streusel for a gluten-free alternative or omit the topping. Ensure spice blends and other packaged ingredients are labeled gluten-free.
Q: How long will leftovers of Tex Mex Chicken and Zucchini keep in the fridge?
