Street Corn Chicken Tostadas are a fun and flavorful twist for busy nights or lazy weekends when you crave something crispy and fresh. The combination of golden tortillas, juicy chicken, and creamy avocado dressing delivers a taste of summer straight from your oven, no grill required. Whenever my family wants something satisfying and a little different, this meal always comes to the rescue.
When I made these the first time, my husband kept talking about that creamy avocado sauce for days and my kids loved stacking their own tostadas with extra lettuce and corn.
Ingredients
- Medium soft white corn tortillas: They toast up perfectly as a crunchy base Look for tortillas without additives for the best flavor
- Chicken breasts: Tender and meaty protein Absorbs marinade well Choose organic or air-chilled if possible
- Italian dressing: Bright zesty tang that doubles as marinade and dressing Pick a high quality bottle with real herbs
- Frozen street corn: Quick and carries lots of summery flavor Try to find bags with roasted corn for deeper taste
- Ripe avocado: Creamy texture and healthy fats Choose slightly soft fruit for easy blending
- Avocado oil or spray: Creates a crisp finish on tortillas and helps everything bake evenly Cold pressed avocado oil adds subtle richness
- Shredded lettuce: Romaine or iceberg for crunch and freshness Go for crisp heads with deep green color
- Lime juice (optional): Brings a pop of acid and brightness Use fresh lime for best results
Instructions
- Prep and Toast the Tortillas:
- Preheat your oven to four hundred degrees Fahrenheit. Brush or spray both sides of each corn tortilla with avocado oil. Arrange them spaced apart on a large baking sheet and bake about ten minutes. Flip them halfway through to ensure they become evenly golden and crisp. Let them cool on a rack so they stay crunchy.
- Marinate the Chicken:
- While the tortillas bake toss the chicken breasts with a quarter cup of Italian dressing in a bowl. Let them marinate on the counter as you prep the rest letting them soak up all those tangy flavors.
- Bake the Chicken and Corn:
- Once the tortillas are toasted remove them to a plate. On the same sheet pan lay the marinated chicken breasts on one side. Bake for twenty minutes. Then add the frozen street corn to the empty side of the tray and return to oven for an additional ten minutes or until chicken reaches one hundred sixty five degrees inside and corn is hot and starting to caramelize.
- Shred the Chicken:
- Transfer the baked chicken breasts to a bowl and use two forks to shred them while still warm. They should pull apart easily especially after roasting in that lively dressing.
- Make the Avocado Dressing:
- In a blend cup blitz together the remaining Italian dressing with a peeled ripe avocado until totally smooth and creamy. Taste and add a squeeze of lime if you want extra brightness.
- Assemble the Tostadas:
- On each crisp tortilla pile a handful of shredded lettuce top with a generous spoonful of juicy chicken a heap of roasted street corn and a swirl of the green creamy dressing. Serve right away while everything is fresh and crunchy.

My favorite part is the roasted street corn Sometimes I sneak a few extra spoonfuls before assembling anything The little smoky char and natural sweetness makes this meal feel special even though it is on the table so fast. My kids now request tostada nights and love layering on their own toppings which has turned our dinners into a fun family assembly line.
Storage Tips
Once assembled these tostadas are best eaten right away since the crispy tortillas can soften with dressing. If you want to prepare ahead store the chicken street corn lettuce and dressing in separate airtight containers in the fridge for up to three days. Warm the chicken and corn just before serving then assemble fresh for the best crunch.
Ingredient Substitutions
No Italian dressing Try lemon juice with olive oil plus a pinch of salt and Italian herbs. Use boneless skinless thighs instead of breasts for extra moisture. If you cannot find street corn plain frozen corn is fine just sprinkle in some chili powder or smoked paprika for flavor. Any sturdy leafy green can work if you do not have lettuce.
Serving Suggestions
Pile your tostadas high with shredded cheese diced tomatoes or jalapenos for extra color and heat. Offer bowls of chopped cilantro sour cream or even a splash of your favorite hot sauce alongside for topping. For a bigger meal add some quick black beans or a simple slaw.
Cultural or Historical Context
Tostadas date back to ancient Mexico when people needed a way to use up day old tortillas by crisping them on hot stones. Today they are a staple in many Mexican households and can be topped with just about anything from seafood to beans and now this oven baked street corn and chicken variation.
Seasonal Adaptations
Use fresh grilled corn in late summer for more flavor Add ripe tomato slices or sweet bell peppers in peak season Switch out lettuce for shredded cabbage in colder months
Success Stories
One friend told me her picky eater finally tried lettuce because he wanted to eat his tostada just like everyone else Another neighbor used leftover grilled chicken for even faster prep and said her family ate every crumb. I have even served these at casual game day gatherings and they disappear fast.
Freezer Meal Conversion
While the tortillas should always be crisped fresh you can freeze the cooked and shredded chicken along with extra street corn. Thaw overnight and reheat then assemble your tostadas in minutes on a hectic night.

With this easy recipe you can bring all the crunch and creaminess of classic street corn to your dinner table, with minimal fuss. Enjoy every bite and feel free to make it your own.
