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