Season the chicken thighs with salt, pepper, garlic powder, cumin, smoked paprika, and chili powder.
Place the seasoned chicken thighs at the bottom of the slow cooker.
Top the chicken with the corn kernels, diced red bell pepper, and minced jalapeño if using.
Pour the chicken broth over the mixture to keep it moist during cooking.
Cover and cook on low for 6-7 hours or high for 3-4 hours, until the chicken is fully cooked and tender.
Once cooked, use two forks to shred the chicken right in the slow cooker. Stir to combine it with the veggies.
In a small bowl, mix the mayonnaise and lime juice. Drizzle it over the shredded chicken mixture and stir in the chopped cilantro and cotija cheese. Adjust seasoning to taste.
Serve the slow cooker street corn chicken warm with tortilla chips or in tortillas for tacos.
Notes
For an appealing look, serve the chicken mixture in a large bowl topped with additional cilantro, crumbled cheese, and lime wedges on the side.
