Heat a large stockpot over medium-high heat. Add the ground beef, chopped onion, and minced garlic. Cook for 7-10 minutes until the beef is browned throughout.
Next, incorporate the pinto beans, kidney beans, tomato sauce, diced tomatoes, tomato paste, and maple syrup into the pot. Stir well to mix all the ingredients.
Add the chili powder, garlic powder, ground cumin, smoked paprika, salt, and black pepper. Pour in 1 cup of beef broth and stir to combine all the flavors.
Bring the chili to a boil, then reduce the heat to low. Let it simmer for 10-15 minutes to allow the flavors to meld and the chili to thicken.
Serve hot, topped with shredded cheddar cheese, Fritos, and chopped green onion. Enjoy your homemade chili!
