01 - Preheat your oven to 425°F. In a large bowl, toss the cut russet potatoes with vegetable oil and salt until evenly coated. Spread the seasoned fries in a single layer on a baking sheet. Bake for 35–40 minutes, flipping halfway through, until they are golden brown and crisp.
02 - While the fries are baking, heat a large skillet over medium heat. Add the ground beef and cook, breaking it up with a spoon, until it is thoroughly browned. Drain any excess fat from the skillet if necessary.
03 - Add the diced onion, minced garlic, and diced red bell pepper to the browned ground beef in the skillet. Sauté for 4–5 minutes, stirring occasionally, until the vegetables have softened.
04 - Stir in the canned diced tomatoes, tomato paste, drained and rinsed kidney beans, chili powder, ground cumin, smoked paprika, cayenne pepper (if using), salt, black pepper, and beef broth. Bring the mixture to a gentle simmer.
05 - Reduce the heat to low, cover the skillet, and allow the chili to simmer for 25–30 minutes. Stir occasionally to prevent sticking, and continue simmering until the chili has thickened to your desired consistency.
06 - Once the fries are cooked, transfer them to an oven-safe platter or baking dish. Spoon the hot chili evenly over the fries, then generously sprinkle with the shredded cheddar cheese.
07 - Place the platter or dish under a hot broiler for 2–3 minutes. Watch carefully to ensure the cheese melts and becomes bubbly without burning.
08 - Remove from the broiler. Garnish the Championship Chili Cheese Fries with sliced green onions and chopped fresh cilantro (if using). Serve immediately while hot.
