Ingredients You Need

Here’s what you need to make this Tex Mex Chicken and Zucchini Recipe:

Protein & Veggies

1 ½ pounds boneless, skinless chicken breasts or thighs, cut in small bite-size pieces
2 medium zucchini, halved lengthwise and sliced into half-moons
1 small red bell pepper, diced
1 small yellow onion, diced
1 cup corn kernels (frozen, canned, or fresh; I often use frozen sweet corn)
1 can (15 ounces) black beans, drained and rinsed

Spices & Seasoning

2 teaspoons chili powder (use a mild American-style blend)
1 teaspoon ground cumin
1 teaspoon smoked paprika (regular paprika works, but smoked adds great flavor)
½ teaspoon dried oregano
½ teaspoon garlic powder
½ teaspoon onion powder
½–1 teaspoon kosher salt, plus more to taste
¼ teaspoon black pepper
Pinch of cayenne or chipotle powder (optional, for extra heat)

Sauce & Mix-ins

1 can (10 ounces) diced tomatoes with green chiles (like Rotel; use mild or hot)
⅓ cup salsa (jarred works great; choose your favorite brand and heat level)
½ cup low-sodium chicken broth (or water with ½ teaspoon bouillon paste)
1 tablespoon tomato paste (from a tube keeps well in the fridge)
1 tablespoon fresh lime juice (about ½ lime)

Cheese & Toppings

1–1 ½ cups shredded cheese (Mexican blend, Colby Jack, or cheddar)
¼ cup chopped fresh cilantro
Sliced green onions, for garnish
Diced avocado, for serving
Plain Greek yogurt or sour cream, for serving

Pantry shortcuts & notes

Use pre-shredded cheese to save time; I like a Mexican blend for this.
Use taco seasoning (about 2–3 tablespoons) in place of the spice list if you want a shortcut.
Use rotisserie chicken or leftover grilled chicken and add it later in the cooking process.

Equipment

Large, deep skillet or sauté pan (12-inch) or a wide Dutch oven
Cutting board and sharp knife
Wooden spoon or spatula
Measuring spoons and cups
Small bowl for spice mix (optional but helpful)

Quick Tips & substitutions

Cut the chicken in small, even pieces so it cooks quickly and stays juicy.
Pat chicken dry before seasoning so it browns instead of steaming.
Use taco seasoning if you want a shortcut; just reduce added salt and taste as you go.
Swap black beans with pinto beans or kidney beans if that’s what you have.
Use yellow squash in place of zucchini or mix both for extra color.
Use frozen corn straight from the freezer; no need to thaw.
Use dairy-free cheese and yogurt if you need a dairy-free version.
Add extra broth if you want it saucier, or simmer longer to thicken.
Adjust heat with more or less cayenne, hot salsa, or tomatoes with green chiles.
Turn leftovers into tacos, burritos, quesadillas, or burrito bowls the next day.

How to Make Tex Mex Chicken and Zucchini Recipe

Step 1: Sauté veggies and aromatics

Heat 1–2 tablespoons oil in a large skillet over medium-high heat. Add diced onion and bell pepper and cook until they soften and turn lightly golden, about 5–6 minutes, stirring often. Stir in corn and cook 2 more minutes so it picks up some color and sweetness.

Sprinkle in a pinch of salt and pepper to season the veggies. Transfer the veggies to a bowl and keep them nearby.

Step 2: Season and brown the chicken

In a small bowl, mix chili powder, cumin, smoked paprika, oregano, garlic powder, onion powder, salt, black pepper, and cayenne or chipotle if you use it. Pat the chicken pieces dry with paper towels and toss them with about two-thirds of the spice mix. Coat the chicken well so every piece carries flavor.

Add another drizzle of oil to the same skillet and keep heat at medium-high. Add the seasoned chicken in a single layer and cook, undisturbed, for 3–4 minutes so it browns. Stir and cook another 3–4 minutes until the chicken cooks through and no pink remains.

Step 3: Add zucchini and build the sauce

Add the sliced zucchini to the skillet with the chicken and sprinkle with the remaining spice mix. Stir and cook 3–4 minutes until the zucchini starts to soften but still holds some bite. Add the cooked veggies back to the pan and stir everything together.

Pour in diced tomatoes with green chiles, salsa, chicken broth, and tomato paste. Stir well to dissolve the tomato paste and coat everything in the sauce. Bring the mixture to a gentle simmer.

Step 4: Simmer and finish with cheese

Lower the heat to medium or medium-low and let the skillet simmer for 5–8 minutes. Stir occasionally so nothing sticks and the flavors blend. Taste and adjust salt, pepper, or heat as needed.

Sprinkle shredded cheese evenly over the top of the skillet. Cover the pan with a lid, turn heat to low, and let the cheese melt for 2–3 minutes. Squeeze lime juice over the top and scatter cilantro and green onions before serving.

Step 5: Serve and enjoy

Spoon Tex Mex Chicken and Zucchini Recipe into bowls or over rice, cauliflower rice, or cooked quinoa. Add avocado and a dollop of Greek yogurt or sour cream. Serve hot while the cheese stays melty and the zucchini still feels tender-crisp.

Recipe Variations

Gluten-free: Use gluten-free broth and salsa, and check your spice blends and taco seasoning labels.
Low carb: Skip the beans and corn, add extra zucchini or bell peppers, and serve over cauliflower rice.
Vegan: Swap chicken with canned chickpeas or extra black beans and use dairy-free cheese and yogurt.
Extra protein: Add a can of drained pinto beans or toss in cooked quinoa at the end.
Extra veggies: Stir in baby spinach or kale in the last 2 minutes until it wilts.
Extra cheesy: Add more cheese and broil the skillet briefly until the top bubbles and browns.
Mild version: Use mild salsa, mild tomatoes with green chiles, and skip the cayenne.
Spicy version: Use hot salsa, hot tomatoes with green chiles, and add chopped jalapeño with the onions.

Storage Success

Let the Tex Mex Chicken and Zucchini Recipe cool until just warm, then store it in airtight containers in the fridge for up to 4 days. Reheat on the stovetop over medium heat with a splash of broth or water, or use the microwave in short bursts and stir between rounds. Add fresh toppings like avocado, cilantro, and a squeeze of lime after reheating so they stay bright. Freeze portions in freezer-safe containers for up to 2 months and thaw overnight in the fridge before reheating.
