Brown the Venison:
In a large skillet over medium heat, add olive oil if needed. Cook the ground venison until browned, breaking it up as it cooks. Drain any excess moisture.
Add Aromatics:
Stir in onion and garlic. Cook for 2–3 minutes until softened and fragrant.
Season and Combine:
Add cumin, smoked paprika, and a pinch of salt and pepper. Stir in the Rotel and let simmer for 2 minutes.
Melt the Cheese:
Reduce heat to low. Add Velveeta cubes and stir until fully melted and creamy. Mix in shredded pepper jack cheese until smooth. If the mixture is too thick, add a splash of milk to loosen.
Serve:
Transfer to a serving dish or a slow cooker on warm setting. Top with jalapeños, green onions, or any desired toppings. Serve hot with tortilla chips.
