Preheat your grill or grill pan to medium-high heat. If you don't have a grill, a skillet works perfectly too!
In a small bowl, combine the chili powder, cumin, garlic powder, onion powder, salt, and pepper.
Rub the spice mixture all over the chicken breasts, ensuring they're evenly coated.
Drizzle the chicken with olive oil.
Grill the chicken for 6-8 minutes per side, or until cooked through and the internal temperature reaches 165°F (74°C).
Let the chicken rest for a few minutes before slicing or dicing.
Grill the corn on the same grill (or in a skillet) until lightly charred on all sides, about 8-10 minutes. You can also boil or steam the corn if you prefer, but the grilled flavor is chef's kiss.
Let the corn cool slightly, then carefully cut the kernels off the cob.
In a medium bowl, combine the corn kernels, mayonnaise, sour cream (or Greek yogurt – a great healthy swap!), cotija cheese, cilantro, and chili powder. Mix well.
Taste and adjust seasonings as needed. A squeeze of lime juice can really brighten the flavors!
Rinse the rice under cold water until the water runs clear. This helps remove excess starch and prevents the rice from becoming gummy.
In a medium saucepan, heat the olive oil over medium heat.
Add the chopped onion and cook until softened, about 5 minutes.
Add the minced garlic, cumin, and chili powder and cook for another minute, until fragrant.
Add the rinsed rice to the saucepan and toast it for 2-3 minutes, stirring constantly. This helps the rice absorb the flavors of the spices.
Pour in the chicken broth and bring to a boil.
Reduce the heat to low, cover the saucepan, and simmer for 18-20 minutes, or until the rice is cooked through and the liquid is absorbed. Do not lift the lid during cooking!
Fluff the rice with a fork before serving.
Start with a base of fluffy Mexican rice in a bowl.
Top with the sliced or diced grilled chicken.
Spoon generous amounts of the Mexican street corn over the chicken.
Add your favorite toppings: avocado, black beans, pico de gallo, salsa, a dollop of sour cream, a sprinkle of extra cotija cheese, and a drizzle of hot sauce (if you like it spicy!).
Squeeze a lime wedge over the top for a final burst of freshness.
