As many of you know, when I was growing up, we had a huge summer garden. It was packed with pretty much all the summer vegetables you could imagine.
By the end of summer, our diet consisted of A LOT of zucchini and summer squash. We would have so much squash that we would try to give it away to anyone who wanted some.
If you garden and grow summer squash, you know exactly what I’m talking about.
I came up with this one-skillet dish because it reminded me of a dish my mom used to make. It was a sort of “clean out the fridge” type of dish that consisted of all the summer veggies, some canned beans, and whatever type of protein she had on hand.
I took that idea, added some flavorful spices, and developed the Tex-Mex chicken and vegetable skillet recipe.
It is jam-packed with flavor and the perfect way to use up all the summer produce.
Plus, you’ll LOVE this dish if you’re a flavor fan.

Ingredients for Tex Mex Chicken and Vegetable Skillet recipe
- Zucchini
- Yellow squash
- Sweet corn
- Black beans
- Chicken breast
- Diced tomatoes
- Peppers
- Onions
- Cheese
That’s it! This dish is so easy to put together that it can be done in 30 minutes. I served mine over rice, but honestly, it’s great right out of the pan.
In my mind, it’s sort of a Tex-Mex play on Ratatouille.
Using a different protein
I used chicken breast because it cooks fast and is an excellent lean protein option for weekday meals.
However, you can choose from many different types of meat, or you can opt to leave it meat-free for a vegetarian meal.
My favorite meat options are:
- Ground chicken, ground turkey, or ground beef. Ground beef will bring the strongest flavor to the dish, but it will pair nicely with the flavors and ingredients and give it more of a “chili” vibe. Ground chicken and ground turkey will be closest to the original flavor.
- Rotisserie chicken is a great option if you’re short on time and don’t have an uncooked protein. You’ll want to add the pulled rotisserie chicken at the end of the cooking time to help it warm throughout the dish. Some stores like Costco and Walmart sell pulled rotisserie chicken packages to make it even easier.
- Grilled chicken is a great summer option as well. Just grill it, chop it, or slice it up, and add it to the completed dish.

Substitutions and additions
If you’re looking for easy changes, I have them covered!
We already talked about protein options up above, but some other fun changes you can make are:
- If you’re not a fan of spicy cheese substitute sharp cheddar or Colby Jack in place of the Cabot Habanero cheddar cheese.
- If you have a pack of taco seasoning on hand, you can use it instead of the individual spices.
- Serve it over chopped Romaine lettuce to create a fun twist to the usual taco salad.
- Use pinto beans in place of black beans.
- If you’re short on squash, use eggplant in its place.
- Chopped fresh summer tomatoes can be used in place of canned tomatoes. You may need to add a little moisture to the pan (there may not be as much juice from fresh tomatoes as there is from canned tomatoes), so add a splash of chicken stock, vegetable stock, or water if needed.
- You can use canned or frozen corn instead of fresh from the cob. You’ll need about 1-1/2 cups to equal the three ears it calls for.
- Add some spicy flavor by sauteeing a jalapeno or serrano pepper with the onions and peppers.

Tips for making Tex Mex Chicken and Vegetable Skillet
- Don’t overcook the zucchini and summer squash: This is my biggest tip because overcooked squash means it will texturally be soggy, release a lot of water, and result in a less flavorful and more watery dish.
- Prep in advance: This dish has many chopped aspects, so make sure to prep before you start cooking. That way, you’ll be less rushed when you’re trying to cook.
- Use frozen veggies if needed: Maybe you’re craving this dish in the middle of winter and it’s hard to find fresh summer vegetables. No worries! While I would still use fresh squash (squash does not freeze well) you can easily find and use frozen chopped onions, peppers, and corn.
- One ear of corn will give you about 1/2 cup of corn: this is the average yield for an ear of corn so make sure your ears look small to grab more or use less if you have very large ears of corn.

Freezing this skillet meal
A lot of dishes can freeze really well but this dish is sadly not one of them.
Since zucchini and yellow summer squash are watery they will turn to mush once unfrozen. While I have used frozen zucchini for baked goods (it’s fine for things like zucchini bread) it’s not optimal if you’re looking to eat the zucchini in this form.
If you want to freeze the other items and leave the squash out of the mix until your reheat that could work.
Storage and leftovers
You’ll want to store any leftovers in an airtight container in the refrigerator for up to 3 days.
You can quickly reheat it in the microwave or on the stovetop.
Since you’ll be reheating the dish the zucchini may release a bit more water and become slightly softer. This is normal.

I made this tonight and it was yummy. I used Taco seasoning in lieu of the other spices. I served it without the rice, as a chili. I was trying to cut out carbs.
