01 - Set oven temperature to 425°F for optimal frying conditions.
02 - Combine frozen fries with vegetable oil, paprika, garlic powder, onion powder, salt, and black pepper in a large bowl. Toss thoroughly until evenly coated.
03 - Arrange seasoned fries in a single layer on a baking sheet. Bake for 25-30 minutes, flipping halfway through cooking, until golden brown and crispy throughout.
04 - Heat olive oil in a large skillet over medium heat. Add ground beef and cook for 5-7 minutes, breaking apart with a wooden spoon, until fully browned. Drain excess fat from the pan.
05 - Stir taco seasoning and water into the cooked beef. Reduce heat and simmer for 2-3 minutes, stirring occasionally, until sauce thickens and coats the meat. Remove from heat.
06 - Transfer baked fries to an oven-safe serving platter or keep on the baking sheet. Distribute seasoned beef evenly over the fries. Sprinkle shredded cheddar and Monterey Jack cheeses across the top.
07 - Return to oven and bake for an additional 5-7 minutes until cheese is completely melted and bubbly. Watch closely to prevent burning.
08 - Remove from oven. Scatter diced tomatoes, black olives, jalapeños, green onions, and cilantro over the melted cheese. Dollop sour cream across the top or serve on the side.
09 - Plate while hot and crispy for best texture and flavor experience.
