Heat a deep skillet over medium flame. Add the ground venison, chopped red onion, cumin, salt, and pepper. Stir occasionally and cook until the meat is browned and the onions have softened. You want the venison fully cooked but still juicy.
Turn the heat to low and stir in the pepper jack and cubed Velveeta. Keep stirring gently so the cheese melts evenly without sticking to the bottom. It should turn into a rich, creamy base that smells amazing.
Now, add in your fire-roasted tomatoes, green chilies, and black beans. Stir everything to combine and let it simmer on low for about 5 minutes. This helps all the flavors blend beautifully and thickens the dip just enough.
Pour in the beer little by little, stirring until you get your ideal dip consistency. If you want it thinner, add a bit more. If you're skipping the beer, a splash of milk or broth works fine too.
Take the skillet off the heat and transfer the dip to your serving dish. I like to sprinkle some fresh cilantro or chopped chilies on top for a pop of color. Serve warm with tortilla chips or crunchy veggies—and dig in!
