Slow Cooker Queso Dip
A smooth, creamy, slightly spicy queso dip made in the slow cooker with real cheese, diced tomatoes and green chiles. Stays warm and dippable for the whole party.

Queso is the dip everyone hovers around at a party. This slow cooker version melts deli American cheese and Monterey Jack with a can of diced tomatoes and green chiles into a silky, scoopable dip.
American cheese from the deli counter contains emulsifying salts, so it melts smooth and stays smooth, while the Monterey Jack adds real cheese flavor.
Once it is melted, switch the slow cooker to WARM and it stays perfect for hours.

Ingredient Notes
American cheese: Ask the deli counter for a 1 pound block or thick slices of white or yellow American cheese and cube it. It melts much smoother than shredded cheddar.
Diced tomatoes with green chiles: Sold in 10 oz cans, often under the brand name Rotel. Use the mild or hot version to your taste.
