Begin by dicing vegetables and setting aside. Heat butter in a saute pan over medium heat until melted. Grate cheese into a large bowl and set aside.
Once butter is melted, add in onion, serranos and garlic and saute until softened.
Once softened, add in flour and stir to combine. Cook for around 1 minute, or until the flour smell is cooked off, and then add in milk. Stir to combine and cook just until it begins to thicken.
Once milk has thickened, add in grated cheese and stir until cheese has melted.
To finish, add in heavy cream and stir to combine. You can add additional cream if you notice the queso is too thick. Enjoy!
