Preheat the oven to 400°F (200°C).
Toss diced potatoes with olive oil, paprika, cumin, garlic powder, salt, and pepper.
Spread the potatoes on a baking sheet and roast for 25 to 30 minutes, flipping halfway, until crispy.
Cook ground beef or chicken in a skillet over medium heat until browned.
Add taco seasoning and a splash of water to the meat, then simmer for a few minutes.
In a mixing bowl, combine sour cream, lime juice, and garlic powder until smooth.
Assemble the bowls by adding crispy potatoes, then top with seasoned meat, cheese, corn, black beans, tomatoes, and red onion.
Drizzle the creamy sauce over the bowls and sprinkle chopped cilantro on top.
Serve warm and enjoy.
