Preheat the oven to 425°F and line a baking sheet with parchment paper.
Place the sweet potatoes in a medium bowl and add 2 teaspoons olive oil, garlic powder, smoked paprika, salt, and black pepper. Toss to coat.
Spread the sweet potatoes in a single layer on the prepared baking sheet and roast for 25 to 30 minutes, stirring halfway through, until tender and lightly browned.
Heat 1 teaspoon olive oil in a large skillet over medium-high heat. Add the chicken, garlic powder, onion powder, smoked paprika, salt, and black pepper. Cook for 6 to 8 minutes, stirring occasionally, until browned and the chicken reaches 165°F.
Reduce the heat to medium-low. Add the jalapeño and minced garlic and cook for 1 to 2 minutes, stirring frequently.
Stir the cream cheese, cottage cheese, and Greek yogurt together in a small bowl until blended.
Add the cream cheese mixture to the skillet and stir gently until warmed through and the chicken is coated.
Add the cheddar cheese and stir until melted.
Divide the roasted sweet potatoes evenly among 4 bowls.
Spoon the jalapeño popper chicken over the sweet potatoes and top with sliced green onions.
Notes
Tips and Tricks
Cut evenly - Keep the sweet potato cubes close to ½ inch so they roast at about the same rate.Control the spice - Most of the jalapeño's heat is concentrated around the seeds and inner membrane. Remove both for a milder bowl.Keep the heat low for the sauce - Once you add the cream cheese mixture, medium-low heat is enough. High heat can make the dairy-based sauce separate.Smooth out the cottage cheese - Blend it before adding it to the cream cheese mixture if you don't want visible curds in the finished sauce.
Storing and Reheating
Refrigerator - Store leftovers in an airtight container in the refrigerator for up to 4 days.Freezer - The cooked chicken and sweet potatoes can be frozen, but the dairy-based sauce may change texture after thawing. Refrigerating is the better option for this recipe.Microwave - Reheat individual portions in short intervals until the chicken and sweet potatoes are hot, stirring gently between intervals.Skillet - Reheat the chicken over low heat, stirring occasionally. Add a small spoonful of Greek yogurt after reheating if the sauce needs to be creamier.
