01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper.
02 - Place diced potatoes in a large bowl. Add olive oil, smoked paprika, garlic powder, salt, and black pepper. Toss until potatoes are evenly coated.
03 - Spread seasoned potatoes in a single layer on the prepared baking sheet. Roast for 25 minutes, flipping halfway through cooking, until golden brown and crispy on the edges.
04 - While potatoes roast, heat a large skillet over medium heat. Add ground beef and cook for 5–6 minutes, breaking up with a spoon, until browned. Drain excess fat if needed.
05 - Add chopped onion and minced garlic to the browned beef. Sauté for 2–3 minutes until onion is softened and fragrant.
06 - Stir in taco seasoning, salt, and water. Simmer for 2–3 minutes until sauce has thickened and coats the beef evenly. Remove from heat.
07 - Divide roasted potatoes among four bowls. Top each portion with seasoned taco beef. Arrange cheddar cheese, sour cream, cherry tomatoes, black beans, lettuce, avocado, green onions, cilantro, and jalapeño over the top.
08 - Drizzle with salsa or hot sauce as desired. Serve immediately while potatoes are still crispy.
