01 - Heat olive oil in a large skillet over medium heat. Add the ground beef and cook, breaking it up with a spoon, until browned and cooked through, about 5–6 minutes. Drain excess fat if needed.
02 - Add onion, green bell pepper, jalapeño (if using), and garlic to the skillet. Sauté until vegetables are soft, about 4 minutes.
03 - Stir in cumin, smoked paprika, chili powder, salt, and black pepper. Cook for 1 minute until fragrant.
04 - Add diced tomatoes with green chilies. Stir to combine and cook for 2 minutes.
05 - Reduce heat to low. Add processed cheese cubes and milk, stirring constantly until cheese is melted and mixture is smooth, about 5–7 minutes.
06 - Stir in shredded cheddar cheese and chopped cilantro. Mix until cheese is fully melted and dip is creamy.
07 - Transfer queso dip to a serving bowl. Garnish with extra cilantro. Serve immediately with tortilla chips.
