Ingredients You’ll Need

- Ground chicken – Use lean ground chicken for a lighter, juicy patty. Avoid extra-lean blends (like 99%) so they don’t dry out. You can also substitute with ground turkey or ground beef if preferred.
- Fajita seasoning – A store-bought blend works great here (look near the taco kits at your grocery store), but you can also mix your own with chili powder, cumin, paprika, garlic powder, and oregano.
- Bell Peppers & Onions – Classic fajita veggies! Slice them thin so they cook quickly. Red, yellow, or orange bell peppers add sweetness, and red onion gives great color and bite.
- Guacamole – A dollop adds creaminess and a cool contrast to the warm spices. You can use store-bought or make a quick homemade guacamole with avocado, lime, garlic, and salt.
- Flour Tortillas – Look for street taco size flour tortillas (like Mission brand) so the patties fit perfectly. If using larger tortillas, form wider patties or trim to fit.

Substitutions/Additions
- Protein swap – Don’t have ground chicken? You can use ground turkey or lean ground beef for a slightly different flavor. Just avoid 99% lean blends so the patties stay juicy.
- Cheese add-on – For that classic smashburger feel, sprinkle some shredded cheddar, Monterey Jack, or Mexican blend cheese on the patty while it cooks. It’ll melt right into the tortilla.
- Flavor boosters – Add a dash of hot sauce, chipotle mayo, or pickled jalapeños for a little heat. You can also mix chopped cilantro or lime zest into the guac for extra zing.
- For other toppings, add some shredded cheese, chunky salsa, diced tomatoes, or sour cream.
How to Make Smashburger Tacos

Step 1: Season chicken. Combine the ground chicken with half the fajita seasoning. In a separate bowl, season peppers and onions with the rest of the seasoning.

Step 2: Prepare smashburgers. Add a scoop of chicken to each tortilla and spread as flat and even as you can.

Step 3: Saute veggies. Heat oil in a skillet and add veggies. Cook 5 to 7 minutes, or until slightly caramelized.

Step 4: Cook smashburgers. While the veggies cook, heat oil in another skillet. Add tortillas, chicken side down, and press into the skillet. Cook for 4 to 5 minutes, then flip and cook another minute or two.
Storing and Reheating
Storing:
These smashburger tacos are best enjoyed fresh, but if you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To prevent sogginess, let them cool completely before sealing, and consider layering parchment paper between them if stacking.
Reheating:
For best results, reheat the tacos in a skillet over medium heat for 2–3 minutes per side until warmed through and crispy. You can also bake them on a sheet pan at 350°F for about 10 minutes. Avoid microwaving, as it can make the tortillas rubbery and the filling unevenly heated.

- Press 2 tbsp of the chicken mixture onto a tortilla, making sure it’s as thin as possible so it cooks quickly. I like to use a cookie dough scooper for this, then spread it out with a knife.
- Heat 1 tbsp of olive oil to a medium-sized pan over medium heat. Add the seasoned sliced red peppers and onion. Sauté for 5-7 minutes, stirring occasionally, until the vegetables have softened and started to caramelize. Set aside.olive oil, 2 red bell peppers, 1 white onion
- While the vegetables on cooking, heat 1 tbsp of olive oil in a cast iron or regular skillet over medium-high heat. Once hot, place the tortilla in the pan, chicken side down. Smash it into the pan using a burger press or by firmly pressing down on it with a metal spatula. Cook about 4-5 minutes, or until the chicken is browned. Flip and cook another 1-2 minutes to lightly char the tortilla.8 small flour tortillas
