Preheat your oven according to the instructions on the frozen French fries package. Spread the fries evenly on a baking sheet and drizzle with vegetable oil. Bake according to package instructions until golden and crispy, usually about 20-25 minutes.

Make the Chili

Cook the Beef

In a large skillet, over medium heat, add the ground beef. Cook until browned, breaking it apart with a spatula, for about 5-7 minutes. Drain excess fat.

Add Vegetables and Spices

Add the chopped onion and minced garlic to the skillet with the beef. Sauté for about 3-4 minutes until the onion is translucent.

Combine Remaining Ingredients

Add the kidney beans, diced tomatoes, chili powder, ground cumin, salt, black pepper, and water to the skillet. Stir well to combine all ingredients.

Simmer the Chili

Bring the chili mixture to a boil, then reduce heat to low. Let it simmer for about 15-20 minutes, stirring occasionally, until the chili thickens.

Assemble the Chili Cheese Fries

Combine and Serve

Once the fries are cooked, take them out of the oven and place them on a serving platter. Pour the chili over the fries, then sprinkle the shredded cheddar cheese on top. Optionally, add sour cream and chopped green onions as toppings. Serve immediately.
