    How to Make A Caramelized Onion Quesadilla

    You are not gonna want to skimp on the caramelized onions in this recipe. Their sweetness really makes the dish! We like to add a little brown sugar to them while they cook to bring out their natural sweetness. Caramelized onions echo the sweetness of the squash and help to balance the spiciness of the chipotle crema and just really solidify the whole dish. Here’s how ya make a caramelized onion quesadilla:

    1. Melt butter in a pan, add the sliced onion and let heat do the rest.
    2. Roast the butternut squash until it’s cooked through.
    3. Assemble quesadillas! Layer cheese, then onions, then black beans and lastly butternut squash. Finish it with a little more cheese and fold it over.
    4. Toast the quesadilla in a skillet until the cheese is all melty.
    5. Drizzle chipotle crema over the finished quesadilla and serve!

    Description

    Squash season is upon us, and we’re ready to fall into flavor with these quesadillas filled with sweet and nutty butternut squash, caramelized onions and black beans.

    Ingredients

    • 6 cups O Organics® Shredded low moisture Mozzarella
    • 8 (10-inch) flour tortillas
    • 1½ cups Caramelized Onions
    • 2 cups Roasted Butternut Squash
    • 1 (15-ounce) can O Organics® black beans, drained, rinsed, optional
    • 2½ tablespoons vegetable oil

    Chipotle Crema

    • 1/2 cup O Organics® sour cream
    • 1/3 cup O Organics® heavy cream
    • 3 tablespoons chipotle hot sauce

    For Serving

    • Thinly sliced avocado
    • Fresh cilantro, minced
    • Salsa Verde

    Method

    1. Make the quesadillas. Sprinkle ½ cup cheese on one half of each tortilla. Top with 3 tablespoons caramelized onions and as much butternut squash and black beans, if using, as you like. Sprinkle with ¼ cup cheese and fold tortilla over the filled half.

    2. Heat the oil in a large nonstick skillet over medium-low heat. Once the oil is glistening, working with one at a time, add the quesadillas and cook until browned, then flip and cook until browned and the cheese is melted. Remove from the skillet and repeat, adding 1 teaspoon oil to the skillet for every quesadilla.

    3. Make the crema. In a small bowl, combine sour cream, heavy cream, and hot sauce until smooth.

    4. To serve, cut each quesadilla in quarters and drizzle with chipotle crema. Serve with desired toppings.

      I'm super excited to make these quesadillas. I froze some fresh cubed butternut a few months ago. To you think I can use this? I've never roasted previously frozen squash (I usually use it in soups).
      Thanks
      Tracey

      We think it would work great! We wouldn't thaw it first but roast directly frozen. Hope you enjoy Tracey!

    • Rosemary

      This is very good and similar to something I make. I feel dim as I hadn't thought of using caramelized onion.
      I also have a suggestion for using chipotles to your crema (or sour cream). I used to get irritating every time I opened a can of chipotles w/adobe sauce. I hate wasting food but never used up the rest of the can in time. Skipping all the different ways I tried, I ended up dumping the whole can (sauce & peppers) into a mini food processor and thoroughly puree, wiping down sides to make sure you get it all pureed. I then transfer it to mini ice cube tray, cover, and freeze. Once frozen, pop out the cubes, transfer to a freezer storage container/bag, and use as needed. The next time you chipotles, take x number of the tiny cubes out and let them defrost before blending w/mayonnaise (sandwiches), sour cream, or just to toss into a pot of beans or soup.

      Great tip on freezing the chipotles. We love caramelized onion in this recipe!

    • Shirley

      Loved this! I hardly ever buy butternut squash and never carmelize onions, so this recipe was "outside the box" for me and I loved it! Thank you!

      Thanks Shirley, we are so glad you loved it!!

    • Soph

      Huge hit in our home! Delicious flavors. Added a squeeze of lime just before serving and baked these at 425F for 10min, flip and another 5min. I just prefer baking quesadillas to pan frying so that they all come out hot at the same time.

      Thanks Soph, we are so glad that you enjoyed them!

    • Ivette

      These quesadillas were delicious and easy to make. Huge hit at our house.

      Thanks Ivette, so happy they were a hit!

    • Jenn

      These were such a huge hit for dinner last night and so quick since I roasted the butternut squash earlier in the day! I did use the black beans and really loved the flavor they added.

      Thanks! so happy you liked them!
