Summer squash with Tex-Mex seasoning is a great way to enjoy fresh squash from the farmers market. With crunchy tortilla chips as a base you’ll love this cheesy Tex-Mex casserole.
Hearty enough for meatless Mondays or served as a side, you’ll want to try this spiced up squash casserole.
If you think you’ve done everything possible with your summer squash, and your family is sick of it, I have just the solution for you. Don’t roll your eyes thinking this is just another blah squash casserole, it’s not even a little boring. This squash casserole recipe is spicy, and bursting with flavor and somehow the tortilla chips stay crunchy.
I was planning on serving this as a side with shrimp one night, but it was so good, I put the shrimp back in the fridge and we enjoyed it all by itself. With all the flavors you could even trick your squash haters into eating this. Since you’re sautéing the squash, frozen squash will work when you run out of fresh squash.
With a little crunch from tortilla chips and spice from the seasoning, you get both texture and flavor that’s hard to achieve with summer squash all by itself.

Barbara’s Tips + Notes
- You can adjust how spicy it is by adding the seeds of the jalapeno if you want it spicy, or leaving it out altogether for a milder version.
- This is best served the same day. The juice from the squash mixture will make the tortilla chips mushy if it sits overnight, still delicious but the texture isn’t quite the same.
- You can substitute any of your favorite cheeses for the pepper jack and cheddar.
- You could use frozen squash if squash are not in season.
