01 - Preheat your oven to 425°F.
02 - Toss the fries with olive oil and a pinch of salt. Spread in a single layer on a baking sheet.
03 - Bake fries for 25–30 minutes, turning halfway, until golden and crisp.
04 - While fries bake, heat vegetable oil in a large skillet over medium heat. Add onion and cook for 2–3 minutes until soft. Add garlic and red bell pepper; sauté for another 2 minutes.
05 - Add ground beef, breaking it up with a spoon, and cook until browned, about 6 minutes.
06 - Stir in tomato paste, chili powder, cumin, smoked paprika, cayenne, salt, and black pepper. Cook for 1 minute to toast spices.
07 - Add diced tomatoes, kidney beans, and beef broth. Mix well, bring to a simmer, then reduce heat to low and cook uncovered for 20–25 minutes, stirring occasionally, until chili thickens.
08 - Remove fries from oven and transfer to a large ovenproof dish. Spoon hot beef chili evenly over the fries.
09 - Sprinkle shredded cheddar cheese generously over the top. Return to oven and bake for 5–7 minutes, just until cheese is melted and bubbly.
10 - Garnish with green onions, cilantro, and jalapeño slices if desired. Serve immediately.
