Cheesy Calabacitas

Cheesy Calabacitas is a dish of summer squash with onions and green chiles, and it’s the perfect side dish to make with zucchini. My recipe omits the corn and/or tomatoes that are sometimes used in Calabacitas which makes this a low-carb side dish!

Calabacitas is a quick and easy way to cook summer squash when they’re abundant, and if you like the idea of cheesy zucchini with green chiles you’ll probably enjoy this recipe. Some recipes for Calabacitas include things like corn or tomatoes, but for my lower-carb version I concentrate on the flavors of the squash, onions, green chiles, and of course plenty of cheese.

This is definitely a recipe that should be made to individual taste, and when I first made this I thought a 4 oz. can of diced green chiles was plenty spicy, but now I use two cans! 

And this Cheesy Calabacitas recipe can certainly be used for a vegetable side dish, but when I have a lot of zucchini and summer squash I’d happily eat a big plate of this for a meatless lunch or dinner.

What is Calabacitas?

Calabacitas is the name that’s used to describe a way to cook summer squash or zucchini that’s common in Mexico or the American Southwest. This recipe is sometimes called Mexican Zucchini. Calabacitas always includes zucchini or summer squash, onions, green chiles, and cheese, and some versions add other ingredients like corn, tomatoes, or red pepper.

How low in carbs is my Cheesy Calabacitas?

My cheesy version of this favorite summer squash recipe without corn or tomatoes has only about 10 net carbs per serving!

What type of Green Chiles are used in Calabacitas?

There are quite a few different varieties of Mexican Chile Peppers that are green. But for this recipe I’m just using the diced green chiles that are found in the grocery store. The canned green chiles you find will usually be relatively mild Anaheim Chiles or Hatch Chile Peppers. Unless you really like spicy food I wouldn’t use hotter chiles in this recipe.

An important tip for making Calabacitas:

Calabacitas is an easy recipe that’s quick to make. But one key to get amazing flavor here is browning the onions and then the squash as they cook; as long as you manage to let them cook without turning long enough to get nicely browned, you can’t go wrong with this easy recipe.

How to Make Cheesy Calabacitas:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

1. Chop onions and open one or two 4 oz. cans of diced green chiles (affiliate link), depending on how much heat you prefer.
2. Cut the squash lengthwise into fourths, then slice the pieces into slices about 3/4 inch thick. 
3. Heat the olive oil over medium-high heat and then cook the onions until they’re barely starting to brown, about 3 minutes.
4. Add garlic and Spike Seasoning (affiliate link) and cook 1-2 minutes longer. 
5. Add the squash and cook about 3 minutes without turning to get the squash lightly browned.
6. Add the cans of green chiles, stir, cover the pan, and cook about 3 minutes more or until the squash is barely starting to soften. 
7. When the squash is barely tender, season well with salt and fresh-ground black pepper.
8. Add most of the two cups of grated cheese (more or less to taste), stir gently, and cook about 2 minutes to melt all the cheese.
9. Sprinkle a little more cheese on at the end and let it melt as you serve it.
10. This won’t win any beauty contests when its done, but it’s truly delicious.

Cheesy Calabacitas is side dish of zucchini and yellow summer squash with onions and green chiles, and of course lots of cheese!

Ingredients

• 1 onion, chopped
• 4 medium zucchini or yellow summer squash (see notes)
• 2 T olive oil
• 1 T minced garlic
• 2 tsp. Spike Seasoning
• two 4 oz. cans diced green chiles (see notes)
• 2 cups grated Mexican cheese blend (more or less to taste)
• salt and fresh ground black pepper to taste

Instructions

1. Chop onions and open one or two 4 oz. cans of diced green chiles (affiliate link), depending on how much heat you prefer.
2. Cut the squash lengthwise into fourths, then slice the pieces into slices about 3/4 inch thick. 
3. Heat the olive oil over medium-high heat and then cook the onions until they're barely starting to brown, about 3 minutes.
4. Add garlic and Spike Seasoning (affiliate link) and cook 1-2 minutes longer. (Use any all-purpose seasoning blend if you don't have Spike.)
5. Add the squash and cook about 3 minutes without turning to get the squash lightly browned on one side.
6. Then add the cans of green chiles, stir to distribute, cover the pan, and cook about 3 minutes more or until the squash is barely starting to soften.
7. I like the zucchini to be slightly tender-crisp. Cook longer if you want it softer.
8. When the squash is barely tender, season well with salt and fresh-ground black pepper.
9. Add most of the two cups of grated cheese (more or less to taste), stir gently, and cook about 2 minutes to melt all the cheese. 
10. Sprinkle a little more cheese on at the end and let it melt as you serve it.

Notes

Use zucchini or yellow summer squash that's about 8-10 inches long; we used about 2.5 lbs. of squash.

You can use one or two 4 oz. can of green chiles, depending on how hot you want it. These are mild green chiles; don’t use Jalapenos unless you like really spicy food.
