Step‑by‑Step Instructions for Tostones Fajita Sliders
Step 1: Sauté Chicken
Heat a tablespoon of olive oil in a medium saucepan over medium-high heat. Add the chopped boneless skinless chicken breast to the pan and sprinkle with taco seasoning. Cook for about 7-10 minutes, stirring occasionally until the chicken is browned and cooked through, with no pink remaining. Once done, transfer the chicken to a plate and cover to keep warm.
Step 2: Cook Fajita Veggies
In the same pan, add a bit more olive oil if needed, then toss in the fajita veggies. Sauté them over medium-high heat for about 5-7 minutes, stirring frequently, until the peppers and onions are tender and slightly caramelized. Once done, remove from heat and set aside with the chicken for later assembly.
Step 3: Prepare Tostones
Start by peeling the green plantains and cutting them into quarters. In a large frying pan, heat about 1-2 inches of coconut oil over medium-high heat until shimmering. Carefully add the plantain quarters to the hot oil and fry for about 5 minutes on each side, or until they are lightly golden but not browned. Remove them from the oil and let them drain on paper towels.
Step 4: Smash and Fry Tostones
Using a flat object like a hammer or the bottom of a mug, gently smash each fried plantain quarter until flattened to about half an inch thick. Return the flattened tostones to the hot oil and fry again for 3 minutes on each side until they are crispy and golden brown. Season with salt immediately after removing them from the oil.
Step 5: Assemble Tostones Fajita Sliders
To assemble your Tostones Fajita Sliders, start by placing a crispy tostone on a plate as the base. Spread a generous layer of guacamole on top, followed by a scoop of the sautéed fajita chicken and veggies. Add a spoonful of pico de gallo or salsa, and if desired, drizzle with cilantro ranch dressing for a burst of flavor.
Step 6: Serve and Enjoy
These Tostones Fajita Sliders can be served warm for the best flavor experience. Consider pairing them with extra guacamole or a fresh salad on the side for a complete meal. They’re perfect for family dinners or friendly gatherings, adding a festive touch to your table.

Expert Tips for Tostones Fajita Sliders
-
Choose the Right Plantains: Use firm, green plantains for optimal texture; overly ripe ones will be too soft for frying.
-
Prep Ahead: Consider preparing taco seasoning and chopping veggies beforehand to streamline your cooking process, leaving more time to enjoy!
-
Smashing Technique: For uniform tostones, aim for gentle, even pressure when smashing. This ensures they cook evenly and maintain their crispiness.
-
Double Frying: Remember, the secret to achieving that perfect crunch is double frying the tostones. First fry for a golden color, and then smash and fry again for ultimate crispness.
-
Customize with Toppings: Feel free to mix and match toppings based on your family’s preferences. Extra guacamole or a spicy salsa can elevate these Tostones Fajita Sliders even further!
Make Ahead Options
These Tostones Fajita Sliders are a fantastic choice for meal prep, saving you time on busy weeknights! You can prepare the chicken and fajita veggies up to 3 days in advance; just sauté them, let cool, and refrigerate in airtight containers. The tostones can be made ahead as well—simply fry them, cool, and freeze the flattened plantains. Then, when you’re ready to serve, fry the frozen tostones directly from the freezer until crispy, about 5-7 minutes. Assemble the sliders just before serving to keep the tostones crunchy and the filling fresh and vibrant. By preparing these components ahead of time, you’ll have delicious Tostones Fajita Sliders ready in minutes!

Tostones Fajita Sliders Recipe FAQs

What should I do if my tostones come out too soft?
