01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Toss diced potatoes with olive oil, smoked paprika, salt, and pepper until evenly coated.
03 - Spread potatoes in a single layer on the prepared baking sheet. Roast for 25-30 minutes, stirring halfway through, until golden brown and crispy.
04 - While potatoes roast, heat a large skillet over medium-high heat. Add ground beef and cook, breaking up with a spoon, until browned, about 5 minutes.
05 - Add diced onion to the skillet and cook until softened, about 3 minutes. Add minced garlic and cook for 1 minute until fragrant.
06 - Stir in chili powder, cumin, oregano, smoked paprika, salt, and pepper. Mix well to combine with the beef mixture.
07 - Add tomato paste and stir to coat the beef evenly. Pour in beef broth or water, reduce heat to medium, and simmer for 3-4 minutes until sauce thickens.
08 - Divide roasted potatoes among four bowls. Top each bowl with the seasoned ground beef mixture.
09 - Garnish with cheddar cheese, cherry tomatoes, black beans, green onions, cilantro, avocado slices, and a dollop of sour cream. Serve immediately with lime wedges on the side.
