These Sweet Potato Nachos layer roasted sweet potato rounds with taco-seasoned ground beef, melty cheese, and fresh toppings for a lighter take on classic nachos. They're a fun, satisfying dinner that's packed with bold flavor and perfect for weeknights or game day.
Place the sweet potato rounds on a greased baking sheet. Drizzle with a little oil and sprinkle with salt, pepper, chili powder, and onion powder. Toss to coat evenly.
Roast for 20-25 minutes, flipping halfway through, until tender and lightly browned.
While the sweet potatoes are roasting, heat a skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a spatula, until browned and cooked through, about 6-8 minutes.
Drain excess fat if needed. Stir in the taco seasoning and taco sauce. Cook for another 2-3 minutes until well combined and heated through. Remove from heat.
Once the sweet potatoes are cooked, evenly spread the ground beef mixture on top and sprinkle with cheese. Return to the oven and broil for 2-3 minutes, just until the cheese is melted and bubbly.
Top the nachos with cubed avocado, halved cherry tomatoes, finely diced red onion, and a drizzle of sour cream. Sprinkle with freshly chopped cilantro if desired.
