While you're gathering ingredients, finely dice the jalapeños into 1/4-inch pieces and remove the seeds—this gives you control over the heat level of your dip. In a small bowl, combine the ground turkey with the garlic powder and chili powder, mixing gently with your hands until the seasonings are evenly distributed. I like to remove the seeds from the jalapeños completely unless you really want serious heat; the flavor of the pepper is what makes this dip special, not just the spice.
Heat a skillet over medium-high heat and cook the seasoned turkey, breaking it up with a spoon as it cooks, until it's no longer pink and has started to brown slightly, about 5-7 minutes. Once cooked through, transfer the turkey to a fine-mesh strainer or colander and let it drain for a minute to remove excess grease. This step is crucial—any leftover grease will make your dip greasy, so don't skip the draining.
Transfer the drained cooked turkey to your crock pot and add the queso blanco, diced tomatoes with green chilies, and prepared jalapeños. Set the crock pot to high heat and stir everything together, then let it cook for 15-20 minutes, stirring occasionally, until the cheese is completely melted and the dip is smooth and creamy. I find that Velveeta Blanco melts beautifully without any lumps, which is why I always reach for it in this recipe—it creates that perfect creamy consistency that regular cheddar can't quite achieve.
Once the dip is smooth and fully heated through, transfer it to a serving bowl or leave it in the crock pot on the warm setting if you're serving it at a gathering. Serve immediately with your favorite tortilla chips or crackers for dipping.
