Preheat the oven to 400° F.

In a large pot, melt the butter over low heat. Remove two (2) tablespoons and set aside in a medium bowl.

Add the milk and lager to the pot and bring to a steady simmer – season to taste with salt and pepper. Add the macaroni and cook, stirring regularly, until the macaroni is mostly cooked through and creamy, around 10-12 minutes.

Add in the cheddar, mozzarella, and fontina. Continue cooking until the cheese is completely melted and very creamy, another 3-4 minutes.

Remove the pot from heat and transfer the macaroni mixture to a medium casserole dish.

To the reserved butter, add the garlic, breadcrumbs, and parmesan; mix well. Spread the breadcrumb mixture on top of the macaroni.

Place in the oven to bake until golden brown and crispy on top, approximately 15-20 minutes. Allow to cool for 10-15 minutes before serving. Enjoy!
