Ingredients You Need

Chicken and Veggies

1 ½ pounds boneless skinless chicken breast, cut into small bite-size pieces
- You can use boneless skinless chicken thighs for extra juiciness.
2 medium zucchini, halved lengthwise and sliced into half moons
1 small red bell pepper, diced
1 small yellow onion, diced
1 cup frozen corn kernels
- Canned corn works too; drain it well.
1 jalapeño, seeded and finely chopped (optional, for heat)
2 cloves garlic, minced

Seasoning and Sauce

2 tablespoons olive oil or avocado oil
2 to 2 ½ tablespoons taco seasoning
- Use your favorite packet or homemade blend; I like McCormick or Siete.
½ teaspoon ground cumin, for extra smokiness
½ teaspoon chili powder, to deepen the Tex Mex flavor
½ teaspoon kosher salt, plus more to taste
¼ teaspoon black pepper
1 can (10 ounces) diced tomatoes with green chiles
- Rotel style tomatoes work great and keep the recipe simple.
¼ cup low sodium chicken broth or water
Juice of 1 lime

Cheese and Toppings

1 to 1 ½ cups shredded Mexican blend cheese
- Cheddar or Monterey Jack also work; pre-shredded saves time.
¼ cup chopped fresh cilantro
Sliced green onions, for garnish
Optional toppings: diced avocado, salsa, hot sauce, shredded lettuce, Greek yogurt or sour cream

Pantry Shortcuts

Use store bought taco seasoning instead of measuring individual spices.
Use frozen pre chopped onions and peppers to cut prep time.
Use pre shredded cheese to keep this weeknight friendly.

Equipment List

Large, deep skillet or sauté pan (12 inch works best)
Cutting board and sharp knife
Wooden spoon or spatula
Measuring spoons and cups
Small bowl for mixing spices, if you prefer

Quick Tips & substitutions

Cut chicken into small, even pieces so it cooks quickly and stays juicy.
Pat chicken dry before seasoning so it browns instead of steams.
Use chicken thighs if you want richer flavor and more forgiveness on cook time.
Swap zucchini with yellow squash if that is what you have.
Use black beans or pinto beans instead of corn for extra protein.
Skip jalapeño or remove all seeds if you prefer mild flavor.
Use dairy free shredded cheese and coconut yogurt to keep it dairy free.
Use low sodium broth and low sodium taco seasoning to control salt levels.
Serve over cauliflower rice instead of tortillas if you want lower carbs.
Double the recipe in a large skillet and use leftovers for meal prep lunches.

How to Make Tex Mex Chicken and Zucchini Recipe

Step 1: Prep the Ingredients

Chop the chicken into small bite-size cubes and place them in a bowl. Pat them dry with paper towels so the seasoning sticks well. Slice the zucchini into half moons, dice the onion and bell pepper, mince the garlic, and chop the jalapeño if you use it.

Measure the taco seasoning, cumin, chili powder, salt, and pepper. Open the can of diced tomatoes with green chiles and keep it nearby. Shred the cheese if you use a block.

Step 2: Season and Brown the Chicken

Sprinkle the chicken with about half of the taco seasoning, plus a pinch of salt and pepper. Toss until every piece looks coated. Heat 1 tablespoon of oil in the skillet over medium high heat.

Add the seasoned chicken in a single layer and let it sit for a minute so it browns. Stir and cook until the chicken looks cooked through and lightly browned on the edges, about 5 to 7 minutes. Transfer the chicken to a plate and keep it nearby.

Step 3: Sauté the Veggies

Add the remaining tablespoon of oil to the same skillet. Add onion, bell pepper, and jalapeño. Stir and cook until the onion softens and turns translucent, about 3 to 4 minutes.

Add the zucchini and corn to the skillet. Sprinkle the remaining taco seasoning, cumin, chili powder, and a little more salt over the veggies. Stir and cook until the zucchini turns tender but still holds some bite, about 4 to 5 minutes.

Step 4: Add Garlic, Tomatoes, and Broth

Stir in the minced garlic and cook for about 30 seconds, just until it smells fragrant. Pour in the diced tomatoes with green chiles and the chicken broth or water. Stir everything together and scrape the bottom of the pan to pick up any browned bits.

Let the mixture simmer for 2 to 3 minutes so the flavors blend and the liquid thickens slightly. Squeeze in the lime juice and stir again. Taste and adjust salt or spice level as you like.

Step 5: Return Chicken and Add Cheese

Add the cooked chicken and any juices from the plate back into the skillet. Stir until the chicken nestles into the veggies and sauce. Spread the mixture into an even layer.

Sprinkle the shredded cheese evenly over the top. Lower the heat to medium low and cover the skillet with a lid. Cook for 2 to 3 minutes until the cheese melts and turns bubbly around the edges.

Step 6: Finish and Garnish

Turn off the heat and uncover the skillet. Sprinkle chopped cilantro and sliced green onions over the top. Add any extra toppings you like, such as diced avocado or a drizzle of salsa.

Let the skillet sit for a couple of minutes so it thickens slightly and cools to a comfortable eating temperature. Serve it hot with your favorite sides or tortillas. Enjoy that cheesy, spicy, veggie packed goodness.
