Start by heating a medium skillet over medium heat. Add your ground beef along with finely chopped onion and minced garlic. Cook for about 7-8 minutes, stirring occasionally, until the beef is browned and the onions are translucent. Make sure to drain any excess fat to keep your chili rich but not greasy.

Once your beef is browned, stir in the tomato sauce, chili powder, cumin, smoked paprika, cayenne (if desired), salt, black pepper, sugar, and a splash of water or broth. Mix everything thoroughly and allow the flavors to meld together.

Reduce the heat to low and let your chili mixture simmer for 15-20 minutes, stirring occasionally.

While the chili simmers, grill or pan-fry your hot dogs until heated through and start to brown slightly, about 5-7 minutes.

Once the hot dogs are grilled and the chili is simmered to perfection, place each hot dog in its bun, generously spooning the warm chili over the top. Then, sprinkle a good amount of shredded cheddar cheese on each one.

Garnish your chili dogs with optional toppings like crunchy raw onions, mustard, or mayonnaise for added flavor. Serve immediately.
