Why Make This Tex Mex Chicken and Zucchini Recipe at Home

This Tex Mex Chicken and Zucchini Recipe packs juicy chicken, tender zucchini, sweet corn, and melty cheese into one skillet that tastes like a lighter version of a cheesy Tex Mex casserole.

Ingredients You Need

Here is what you need to make this Tex Mex Chicken and Zucchini Recipe at home:

Chicken
- 1 ½ pounds boneless skinless chicken breasts or thighs, cut into small bite-size pieces
  - Thighs stay juicier and forgive overcooking a bit more.
Vegetables
- 2 medium zucchini, quartered 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; frozen works great straight from the bag)
- 1 jalapeño, seeded and finely chopped (optional, for heat)
- 2 cloves garlic, minced
Spices and seasoning
- 1 ½ teaspoons chili powder
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika (regular paprika works, but smoked adds nice depth)
- ½ teaspoon dried oregano
- ½ teaspoon kosher salt, plus more to taste
- ¼ teaspoon black pepper
- ¼ teaspoon ground coriander (optional but tasty)
Sauce and extras
- 1 can (10 ounces) diced tomatoes with green chiles (like Rotel; use mild or hot)
- ¼ cup tomato sauce or salsa (jarred salsa works great as a shortcut)
- 1 tablespoon tomato paste (adds richness; squeeze tube style keeps well in the fridge)
- 1 tablespoon fresh lime juice
- ½ cup low sodium chicken broth or water
Cheese and toppings
- 1 to 1 ½ cups shredded cheese (cheddar, Monterey Jack, or a Mexican blend; I like Tillamook or Sargento)
- ¼ cup chopped fresh cilantro
- Sliced green onions
- Diced avocado
- Plain Greek yogurt or sour cream
- Lime wedges
Oil
- 1 to 2 tablespoons olive oil or avocado oil

Pantry shortcuts and substitutions

Use taco seasoning (about 2 to 2 ½ tablespoons) instead of the individual spices if you want a shortcut. Taste and adjust salt since some mixes run salty.
Swap black beans or pinto beans for part of the chicken if you want to stretch the protein or keep it lighter on meat.
Use yellow squash in place of some or all of the zucchini if that is what you have.
Use frozen onion and pepper mix to save chopping time.

Equipment list

Large 12 inch skillet or sauté pan (cast iron or nonstick both work)
Cutting board and sharp knife
Wooden spoon or spatula
Measuring spoons and cups
Cheese grater if you shred your own cheese

Tips & Mistakes

Cut chicken and zucchini into similar size pieces so everything cooks evenly and you avoid mushy zucchini with undercooked chicken.
Pat chicken dry and season it before it hits the pan so it browns instead of steaming.
Heat the skillet properly and avoid crowding the chicken; cook in two batches if needed to keep good browning.
Add zucchini after the chicken cooks most of the way so the zucchini stays tender-crisp instead of soggy.
Taste the mixture before adding cheese and adjust salt, lime juice, or chili powder so the flavor pops.
Use freshly shredded cheese when possible because bagged cheese often contains anti-caking agents that make it melt less smoothly.
Keep jalapeño seeds and membranes out if you prefer mild heat; leave some in or add a pinch of cayenne if you like it spicy.
Do not overcook the skillet after adding cheese; melt it gently so it stays gooey and does not turn rubbery.
Let the skillet rest a couple of minutes before serving so the sauce thickens slightly and clings to the chicken and veggies.

How to Make Tex Mex Chicken and Zucchini Recipe

Step 1: Prep the chicken and veggies

Cut the chicken into small bite-size pieces, about ¾ inch cubes, and place them in a bowl. Pat them dry with paper towels, then season with a pinch of salt, pepper, and a little chili powder. Chop the zucchini, onion, bell pepper, jalapeño, and garlic so they stand ready to go.

Measure out the spices in a small bowl so you can add them quickly. Open the can of tomatoes with green chiles and drain off just a little liquid if it looks very watery. Keep the corn nearby so you can toss it in when needed.

Step 2: Brown the chicken

Heat 1 tablespoon of oil in a large skillet over medium high heat. When the oil shimmers, add the chicken in a single layer and let it sit for 2 to 3 minutes so it browns on one side. Stir and cook another 3 to 4 minutes until the chicken looks mostly cooked through and has some golden spots.

Taste a small piece to check seasoning and add a pinch of salt if it tastes flat. Transfer the chicken to a plate and keep it nearby. Leave the browned bits in the pan because they add flavor to the veggies.

Step 3: Sauté veggies and aromatics

Add another drizzle of oil to the same skillet if it looks dry, then drop in the onion, bell pepper, and jalapeño. Cook over medium heat for about 4 to 5 minutes, stirring often, until the onion softens and turns slightly translucent. Add the garlic and cook 30 seconds until it smells fragrant.

Stir in the chili powder, cumin, smoked paprika, oregano, coriander, salt, and pepper. Toast the spices for about 30 seconds so they bloom and release flavor. Scrape the bottom of the pan as you stir so the spices mix with the browned bits.

Step 4: Add zucchini, corn, and saucy ingredients

Add the zucchini and corn to the skillet and stir to coat them in the spices and aromatics. Cook 3 to 4 minutes until the zucchini starts to soften but still feels a little firm. Pour in the diced tomatoes with green chiles, tomato sauce or salsa, tomato paste, and chicken broth.

Stir everything together and bring the mixture to a gentle simmer. Let it bubble for about 4 to 5 minutes so the flavors mingle and the sauce thickens slightly. Taste and adjust salt or chili powder if needed.

Step 5: Return chicken and finish cooking

Return the browned chicken and any juices from the plate to the skillet. Stir to combine with the veggies and sauce. Simmer another 3 to 5 minutes over medium heat until the chicken cooks through and the zucchini turns tender but not mushy.

Squeeze in the lime juice and stir again. Taste one more time and tweak salt, pepper, or lime to your liking. Turn the heat to low so you can add the cheese.

Step 6: Add cheese and toppings

Sprinkle the shredded cheese evenly over the top of the skillet. Cover the pan with a lid and keep the heat on low for 2 to 3 minutes until the cheese melts and turns bubbly around the edges. Remove the lid and admire your cheesy Tex Mex Chicken and Zucchini Recipe masterpiece.

Scatter chopped cilantro and green onions over the top. Add diced avocado or dollops of Greek yogurt or sour cream if you like extra creaminess. Serve straight from the skillet while it stays hot and melty.

Variations I've Tried

Rice skillet version: Stir in 1 to 1 ½ cups cooked rice at the end and let it warm through before adding cheese. This version stretches the meal and tastes like a cheesy Tex Mex chicken and zucchini burrito bowl.
Low carb version: Skip corn and beans and add extra zucchini or bell peppers. Use a lighter hand with the cheese and top with extra salsa and avocado.
Bean and chicken combo: Add 1 can of drained and rinsed black beans with the tomatoes and corn. This adds fiber and stretches the protein so leftovers last longer.
Extra spicy version: Use hot diced tomatoes with green chiles, keep some jalapeño seeds, and add a pinch of cayenne with the spices. I serve this version with extra Greek yogurt to cool things down.
No dairy version: Skip the cheese and finish with extra avocado, cilantro, and a drizzle of olive oil. The skillet still tastes rich because of the spices and veggies.

How to Serve Tex Mex Chicken and Zucchini Recipe

Serve this Tex Mex Chicken and Zucchini Recipe straight from the skillet with warm tortillas on the side so everyone can scoop their own. It also tastes great over rice, quinoa, or cauliflower rice for a bowl-style dinner. Add toppings like shredded lettuce, extra salsa, diced tomatoes, avocado, and a squeeze of lime for a build-your-own Tex Mex bar.

I also like to spoon leftovers into crisp romaine leaves for quick lettuce wraps. A side of tortilla chips with salsa or guacamole turns it into a fun family meal that feels a little like a weeknight party.

How to store

Fridge: Cool the Tex Mex Chicken and Zucchini Recipe to room temperature, then store it in an airtight container in the refrigerator for up to 4 days.
Freezer: Place cooled portions in freezer-safe containers or zip bags, squeeze out extra air, and freeze for up to 2 months; zucchini softens a bit after freezing but still tastes good.
Reheating on stove: Reheat gently in a covered skillet over medium low heat with a splash of broth or water, stirring occasionally until hot.
Reheating in microwave: Warm individual portions in a microwave-safe bowl, loosely covered, in 45 to 60 second bursts, stirring between each burst until heated through.
Cheese refresh: Add a small sprinkle of fresh cheese on top during reheating if you want that freshly melted look and texture.
