01 - Heat a large skillet over medium-high heat. Add ground beef and season with salt, black pepper, cumin, and chili powder. Cook while breaking up the meat until browned and cooked through, approximately 5–6 minutes. Drain excess fat if necessary.
02 - Add diced onion and jalapeño to the seasoned beef. Continue cooking for 2–3 minutes until vegetables become soft and fragrant.
03 - Reduce heat to low setting. Add processed cheese cubes, shredded cheddar, and milk to the skillet. Stir continuously until all cheese is completely melted and the mixture achieves a smooth consistency, about 3–4 minutes.
04 - Incorporate smoked paprika and garlic powder into the cheese mixture. Continue stirring until spices are evenly distributed and the dip reaches a creamy, uniform texture.
05 - Taste the queso dip and modify seasoning levels if needed to achieve desired flavor balance.
06 - Transfer the finished dip to a serving bowl. Sprinkle with chopped fresh cilantro and diced tomato. Serve immediately while warm with tortilla chips for dipping.
