These Easy Rotisserie Chicken Tostadas with Quick Pickled Red Onions could not be more simple but they deserved a permanent spot on the blog! These are beyond flavorful and great when you need a quick, simple meal.

Easy Rotisserie Chicken Tostadas with Quick Pickled Onions

A store-bought rotisserie chicken can go a long way. I can think of so many recipes to make with rotisserie chicken or leftover chicken breasts. And these tostadas are a great example of how you can take simple, shredded rotisserie chicken and make a show-stopping weeknight meal.

If you’ve never had a tostada before let me tell you about why tostadas are so great. It’s essentially a giant chip and chips are…well, the best invention since sliced bread. I love that you can tower them high with taco-like ingredients and essentially eat a salad on top of a giant chip. It’s amazing. And while you can use your hands, you’ll likely need a fork, too!

Also, pickled things are my love language. I love the tangy, vinegary touch on top of savory things to add acidity and brightness to a dish. You can really put them on top of anything to elevate any dish and the best part is, they last for up to 2 weeks in the fridge (although I do prefer them within a week of making them).

Easy Rotisserie Chicken Tostadas with Quick Pickled Onions step-by-step:

Step One: soak the onions

Place the sliced onions in a large bowl and cover in hot water for 5 minutes (this takes out the bite in the onions).

Step Two: Make the Onion brine

Meanwhile, in a jar or bowl large enough for all the onions, whisk together the apple cider vinegar, kosher salt, peppercorns, and coriander seeds, until all the salt has dissolved.

Step Three: Marinate the Onions

When the onions are done soaking, drain off the water. Add the onions to the bowl with the brine. Cover and refrigerate for at least 30 minutes before serving.

Step Four: Make the sauce for the chicken

  1. Delicious! We all loved this recipe so much! I had to share with friends right away! I have never tried one of your recipes and not loved it. Thank you for sharing your brilliant ways!

    1. When the onions are done soaking, drain the onions and combine the brine with onions.

      The above directions make no sense to me.

  2. 5 stars
    Made these tonight and they were a hit. Really delicious and light. This was my first time buying grain-free tortillas and I’m so glad I did!
