01 - Preheat the oven to 425°F. Toss fries with vegetable oil and spread on a baking sheet. Bake according to package instructions or until golden and crispy, about 25-30 minutes.
02 - Heat a large skillet over medium-high heat. Add ground beef and cook, breaking up with a spoon, until browned, about 5 minutes.
03 - Add the finely chopped yellow onion and cook for 3-4 minutes until softened. Stir in garlic and sauté for 1 minute.
04 - Mix in diced tomatoes, tomato paste, kidney beans, cumin, chili powder, paprika, salt, and pepper. Bring to a simmer, reduce heat to low, and cook for 10-15 minutes until thickened.
05 - When fries are ready, transfer them to an oven-safe dish. Pour hot chili evenly over the fries. Sprinkle shredded cheddar cheese on top.
06 - Return the dish to the oven for 3-5 minutes, or until the cheese is melted and bubbling.
07 - Remove from the oven and top with sliced red onion, cilantro, and jalapeños if desired. Serve immediately.
