How to Make Guinness Mac and Cheese

Prepare Béchamel: Begin by heating whole milk over low heat until it’s steaming—this will be the creamy base. In a separate saucepan, melt butter and whisk in flour, cooking for 2-3 minutes to create a roux.
Combine/Mix: Gradually whisk the hot milk into the roux, adding nutmeg as you cook the mixture until thickened. Once done, remove from heat and whisk in crème fraîche and cheeses until everything melts beautifully. Stir in the warmed Guinness and season with salt and white pepper.
Pasta Preparation: Cook mini penne pasta in a pot of boiling salted water until al dente, about 8-10 minutes. Drain and thoroughly combine it with your cheesy sauce for an even coating.
Breadcrumb Topping: In a sauté pan, melt butter and add minced garlic and thyme. Once fragrant, toss in panko bread crumbs and toast until slightly golden, about 2-3 minutes.
Assemble & Bake: Transfer the pasta mixture into a greased baking dish, top with your crispy panko blend, and bake in a preheated oven at 400°F (200°C) until bubbly and golden brown, roughly 20-25 minutes.

Optional: Garnish with freshly chopped parsley for a pop of color and flavor!
