I make this every summer when squash and corn ripen. My sister Leanna grows beautiful squash in her sun soaked Southern California garden. We made calabacitas (call-ah-ba-SEE-tas) with it when she visited me.
I discovered the recipe in the children’s book Carlos and the Squash Plant / Carlos y la planta de calabaza by Jan Romero Stevens. It’s a tale of a boy who won’t wash his ears until a squash plant grows out of his ears. His mom serves him calabacitas when he finally washes the plant out.
I put my own touch on her recipe, by substituting olive oil for margarine, adding oregano, red bell pepper and tomato for color. Our friends Victor and Mary Lau Valle, who are master chefs, brought us homegrown squash and oregano and taught me Victor’s mother’s version, using the Mexican cheeses asadero and cotija. (Victor and Mary are the authors of Recipe of Memory:Five Generations of Mexican Cuisine)
Asadero is a Mexican mozzarella and melts wonderfully. Although it is a low-fat cheese, it has a wonderful buttery taste not usually associated with mozzarella. The cotija we used was a powdery cheese in a bag, (not the kind that comes in a brick.) It made a nice crunchy crust on the casserole when we broiled it.
2 Anaheim peppers and 2 jalapeños (add more jalapeños for extra heat) You can substitute poblano chilies for the Anaheims for a smokier flavor
5 Tb olive oil
1 onion, diced
About 1 tsp ea dried or 2 tsp fresh oregano
5 small to medium summer squash (I used sunburst and zucchini)1 red bell pepper, diced
2 cobs corn. Cut the cobs in 2 crosswise to get a flat surface, then strip the corn from the cob. I sauté the uncooked corn. Sometimes I use cooked corn and skip the sauté step.
3/4 cup of chicken broth. I use Roz’s Jewish Chicken Soup You can make this vegetarian by substituting vegetable broth.
3 Roma tomatoes, chopped
1 1/2 cups asadero cheese, chopped. If you can’t find asadero, substitute Monterey Jack.
1/2 cup powdered cotija cheese
Place chilies directly on a gas flame until they char, then turn until all sides char. If you don’t have a gas stove, use the barbecue. And if you don’t have a barbecue, then char them on a heavy comal or frying pan placed over a burner on high. Place charred chilies in a small pot and cover until they are cool enough to handle. The chilies will sweat and the skin will soften.
While chilies are sweating, chop the vegetables and place them in a cake pan by groups. Start off with the onion, then chop the other veggies while the onion cooks.
Cut the squash at different angles so they’re chunky.
I use a wok to cook this in, but you can use a large heavy frying pan as well.
Sauté onions in 1 Tb olive oil over low heat until translucent, about 10 minutes. Set aside in a large bowl.
Raise the heat and add 2 Tb olive oil to the pan. Add squash with oregano and a pinch of salt. Saute squash until it is beginning to brown on all sides. Add to the onions in the bowl.
Saute red bell pepper and corn in another Tb of oil until they begin to char. Then add to the other veggies in the bowl.
Saute the chopped tomatoes and a pinch of salt in another Tb of olive oil. Be sure to spread the tomatoes out so that they can caramelize. Add 1 tsp more fresh oregano, and cook tomatoes over medium heat until they are mostly dry, Caramelizing the tomatoes concentrates their flavor- they are so delicious!
While tomatoes are cooking, take out the chilies from the pot. Remove the stem and slice them open lengthwise. Scrape the charred parts from the skin, then scrape the seeds and soft parts from the inside. Julienne the chilies into thin strips.
Add the the chilies and the vegetables from the bowl to the tomatoes.
Pour in chicken broth and heat until boiling, stirring vegetables together.
Stir in 1 cup of the asadero or Jack cheese. Spray a flat casserole or 11′ x 8″ cake pan with non-stick spray, and pour the vegetables into it.
Sprinkle the rest of the asadero cheese on top of the calabacitas. Then sprinkle with cotija powdered cheese.
Move a rack to the upper third of the oven and turn on the broiler.
Place under the broiler for 3 -5 minutes, until the cheese turns a golden brown.
Delicious served with corn tortillas to soak up the cheesy sauce. You can mix it in with Frijoles pintos (Mexican pinto beans)
