How to Make Pickled Onions

If you’ve never made pickled onions, they are easier to make than you might think. You can use raw onion in the tacos if you don’t want to pickle them, but I encourage you not to skip this step – they’re so good! Plus, pickled onions will last in your refrigerator for at least two weeks, which means you can add them to salads, burgers, rice bowls, and much more.

  • In a small saucepan, heat apple cider vinegar, water, sugar, and salt until it boils and the sugar dissolves.
  • Pour the hot liquid over the onions and bay leaves in a heat-safe bowl.
  • Let cool, transfer to a glass jar, and refrigerate overnight.

How to Air Fry Cauliflower

The air fryer (affil link) is a quick and easy way to make crispy cauliflower.

  1. Drizzle the cauliflower with olive oil and season with Tajin, smoked paprika, and salt.
  2. Spray the air fryer basket with oil (make sure it’s a spray that’s “propellant- free” – I like Bertolli’s) and add the cauliflower.
  3. Cook at 400 degrees for 12 to 15 minutes, shaking the basket halfway.

If you don’t have an air fryer, roast your cauliflower in the oven at 400 degrees for about 20 minutes.

  • If you don’t have Tajin, substitute it with chili powder.
  • Add avocado or red cabbage for an extra veggie.
  • Omit the sour cream for vegan tacos.
  • If you don’t want to make Peruvian green sauce, use a store-bought salsa verde instead.
  • Use corn tortillas for gluten-free tacos.
  • Swap the tortilla for a lettuce wrap to make low-carb tacos.

  5. This recipe worried me. Cauliflower as an entree? But I’m trying new recipes rn so I went ahead. I broiled the cauliflower in the oven. It was beautiful. Not much protein so I added a bean salad. Beautiful to look at and amazing flavor. Looking forward to tomorrow and lunch leftovers.

  6. These cauliflower tacos are AMAZING!!!!  While eating, I literally kept saying “wow”. Lol. All of the textures, flavors & colors are a wonderful combination.  My Peruvian green sauce had more kick than expected but the sour cream tamed it, while still getting all that flavor. Can’t go w/out the pickled red onion. They are delicious in salads as suggested & I won’t be caught without them now. Lol  Thank you!
