Best baked queso dip with meat in oven is a killer cheese dip with ground sausage or ground beef inside. With no Velveeta, you can make with Rotel or diced tomatoes.
Cut cheeses in large bite size chunks, dice and prepare veggies and put everything in your disposable aluminum pan. (could use a large casserole dish instead) Cover with aluminum foil.
Preheat your oven to 375 degrees F. Once warmed place pan on middle rack and bake for 30 minutes.
Lift foil and stir ingredients together. Recover and bake for another 20 minutes or until everything is melted together.
