🥶 Prepare and freeze your chicken burgers!
Summertime means grilling time, and chicken burgers make an easy 30-minute dinner. I regularly make big batches of several types of burgers, like
- these Open-Faced Harissa Chicken Burgers with Yogurt Sauce,
- these Healthy Open Face Thai Burgers,
- or Chipotle Chicken Burgers with Peach Salsa.
I freeze them on baking sheets, then package, vacuum seal and freeze for busy nights.
🔪 Instructions
Start by prepping the Tomatillo Guacamole. No tomatillos? No worries! Sub your favourite chunky guacamole if you don't have tomatillos. Simply mash avocado with a fork and stir in lime juice, garlic, cilantro and tomatillos or a few chopped tomatoes.
While your burgers are sizzling on the grill, sear some sliced bell peppers (one of each colour is fun) and onions just until softened. These peppers add fabulous Tex-Mex flavours to your burgers, so don't leave them out!
Then assemble and you're ready to devour! Spread a thick layer of guac on a gluten-free bun, add a burger, and top with a generous amount of seared peppers and onions.
OR Keep your meal gluten-free by serving these delicious paleo chicken fajita burgers without a bun. Just add the guacamole on top of the patty before topping with the sliced pepper and onion mix.
❓Frequently asked questions
Very lean ground chicken (or ground turkey) may result in dry burgers. Use a mix of ground chicken thighs and breasts for juicy burgers and best results.
Depending on how thick you make the burgers and the temperature of your grill, these burgers should be cooked for 4-6 minutes per side or longer, or until a meat thermometer (inserted through the side of the burger) registers at least 165°F and the meat is no longer pink inside.

Thanks for this recipe! I made these burgers on the weekend. We had them with regular guacamole as I didn't have any tomatillos. They were moist and juicy. I used the chipotles in adobo as you suggested. Will make again!
