When summertime vegetables like corn, peppers and squash hit the produce stands and farmers’ markets, I turn to this Calabacitas recipe again and again. It’s quick to make and adaptable to whatever you’ve got on hand.

I can hardly think of a more vibrant, colorful combination of tender vegetables than Calabacitas. Tossed in a buttery, rich sauce and finished with crumbled cheese and fresh lime juice, this traditional Mexican dish is both a perfect side to just about any main course and satisfying enough to stand on its own.
Zucchini and yellow summer squash are the star ingredients, supported by yellow and green onions, poblano and red bell peppers, and corn. Butter, olive oil and garlic make up the flavorful sauce, with cilantro, lime wedges and slightly salty cotija cheese as the finishing touches. And while it screams summer, I’ve been known to whip it up in the depths of winter when I need a reminder that warmer days are coming.
I made this last night for dinner and it was so fresh, so flavorful. The squash was tender but the corn, red bell pepper, and poblano are the flavor stars, with the addition of the cotija. So delicious and easy. This will be made regularly in my house this summer. Thanks for another great recipe, Marissa!

What Is Calabacitas
If you’re wondering what this dish is, Calabacitas (a Spanish word that means “little squash”) is a traditional Mexican dish that’s made with a variety of vegetables, like zucchini, corn, peppers, onions, cream, and/or cheese, herbs and spices and sometimes tomatoes.
Ingredients for Calabacitas

- Butter: Use whatever butter you have on hand. If using unsalted, you may want to add a little more salt to the final dish.
- Olive Oil: Use any good extra-virgin olive oil you keep on hand.
- White Onion: I use white onion for this dish, but yellow onion works too.
- Poblano Pepper: If you can’t find a poblano, use an Anaheim pepper instead.
- Red Bell Pepper: Red peppers add the most sweetness, but yellow or orange work too. I don’t recommend green bell peppers for this dish as they can add bitterness.
- Garlic: Use fresh garlic cloves, not powdered or granulated garlic.
- Zucchini: Use small to medium zucchini for the best flavor and texture. If the squashes are very small you may want to add an extra.
- Yellow Summer Squash: Same rule as for zucchini.
- Green Onions: Look for a bright green, perky batch of green onions.
- Fresh Corn Kernels: Nothing beats fresh corn cut right off the cob, but frozen works when fresh corn isn’t in season.
- Cotija Cheese: I love to finish this with cotija, but have used queso fresco and even crumbled feta in a pinch.
- Fresh Cilantro: If you don’t like cilantro, use flat-leaf parsley instead.
- Lime: Fresh lime wedges for serving are optional, but they add a bright, zesty finish that I love.
- Salt and Black Pepper: As always, freshly ground pepper is best.
How to Make Calabacitas
Cook and stir onion, poblano, bell pepper in a sizzling blend of butter and olive, in a large skillet set over medium heat salt until softened. Add garlic and cook until fragrant.






Add zucchini and yellow squash; cook until softened. Then add green onions and corn; simmer without stirring until most of the liquid has cooked off. Stir in remaining butter and season with salt and pepper. Transfer to serving bowl and sprinkle with cotija cheese; serve hot with lime wedges (optional).





Pro Tips
- Don’t overcook the vegetables, they should be tender-crisp. I’ve found that summer squash goes from just right to overcooked quickly.
- If you’re not eating right away, wait to finish with the cheese and cilantro until just before serving.
- Calabacitas makes great leftovers, too. Mix in some leftover chicken or another cooked protein for a satisfying lunch or easy dinner.
- Taste before adding salt. Cotija cheese adds saltiness right at the end, so you might need less added salt than you might think.
- So that all of your vegetables are done at the same time, do all of your prep before you start cooking. Once you begin, this dish comes together quickly.

Recipe Variations
- Swap in a generous splash of heavy cream instead of butter for a creamier sauce.
- Try it with different summer squash varieties – pattypan or crookneck work well too.
- Cotija is traditional, but queso fresco, feta, Monterey Jack, or mozzarella all work well, each bringing a different flavor and texture to the dish.
- For additional flavor and color, stir in a diced ripe tomato.
- Sometimes, I’ll roast the peppers first by drizzling them with a little olive oil on a baking sheet and baking them in a 400-degree oven for about 20 – 25 minutes.
- For a spicy flavor twist, try adding a pinch of cumin or chili powder.
How to Store and Reheat
Store leftover calabacitas in an airtight container in the refrigerator for up to 5 days. Reheat in a large skillet over medium-low heat, stirring occasionally until heated through; adjust seasoning as desired and serve.

Can you make this in advance? Like an hour ahead of time?
Hi Judy! Yes, you can definitely make this an hour ahead. It actually holds its heat pretty well and the flavors continue to meld. Just keep it covered and reheat gently on the stove if needed, stirring occasionally. The zucchini might soften a tiny bit more, but it’ll still be delicious!
I haven’t ever made this before, but this recipe is a winner! Delicious!
