Mexican Calabacitas Recipe
What is calabacitas? Well, in Spanish, calabacitas means zucchini. But there’s definitely more than just zucchini in this dish.
Although most people would consider this calabacitas recipe a side dish, I consider it practically a meal because it keeps me full for hours from all the veggies.
This super flavorful side dish with so many flavors, textures, and vibrant colors is both vegan and gluten-free. You’d never guess it was ‘missing’ anything because it’s so filling.
Because it’s also a warm side dish, it has a comfort-food vibe to it, although it holds great at room temp or can be served chilled.
I gave half the batch to my neighbor because it makes a very big batch and she said her family devoured it and asked for more.
Just wait until you see the volume of food this recipe makes! It makes an easy 6 hearty servings and it also holds well at room temperature, so it’s perfect for parties, picnics, and potlucks.

What’s In Calabacitas?
In my version of Mexican calabacitas, there’s a mixture of:
- Olive Oil
- Onions
- Red and orange bell peppers
- Zucchini
- Fire-roasted green chiles
- Corn
- Cherry tomatoes
- Cumin
- Oregano
- Salt and pepper
- Lime Juice
- Cayenne pepper, optional – The cayenne doesn’t make the dish spicy, but rather flavors a very large skillet of vegetables so that they’re not bland. Mexican-inspired food as we know it doesn’t tend to be bland.
