Pasta provides the perfect canvas, and a simple breadcrumb‑butter mixture adds texture.

Pasta
- 12 oz (340 g) elbow macaroni
Cheese Sauce
- 2 cups whole milk
- 1 cup Guinness stout (or other dry stout)
- 3 tablespoons unsalted butter, divided
- 3 tablespoons all‑purpose flour
- 1 ½ cups grated Irish sharp cheddar
- ½ cup grated Gruyère (optional for extra depth)
Seasonings & Flavor Boosters
- 1 teaspoon Dijon mustard
- ¼ teaspoon freshly grated nutmeg
- Salt and freshly ground black pepper, to taste
Topping
- ½ cup panko breadcrumbs
- 1 tablespoon melted butter
- 1 tablespoon grated Parmesan cheese
The stout‑infused béchamel creates a velvety base that clings to every noodle, while the blend of Irish cheddar and Gruyère guarantees a deep, melt‑in‑your‑mouth richness. Dijon mustard and nutmeg add a subtle zing and warmth, preventing the sauce from feeling one‑dimensional. Finally, the buttery panko topping crisps up under the broiler, delivering that coveted golden crust that makes this mac & cheese unforgettable.
Step-by-Step Instructions
Preparing the Pasta
Bring a large pot of salted water to a rolling boil. Add the elbow macaroni and cook until al dente, about 7–8 minutes. Drain, then toss with a drizzle of olive oil to keep the noodles from sticking while you build the sauce. This step ensures the pasta remains firm enough to hold its shape during baking.
Making the Guinness‑Infused Cheese Sauce
- Build the roux. In a medium saucepan melt 2 tablespoons butter over medium heat. Sprinkle 3 tablespoons flour over the butter, whisking constantly for 2 minutes until the mixture turns a light golden hue. This cooks out the raw flour taste and creates the thickening foundation.
- Deglaze with Guinness. Slowly whisk in 1 cup Guinness stout, allowing the mixture to bubble gently. The liquid will loosen the roux, forming a smooth, slightly amber base. The stout’s caramel notes begin to permeate the sauce at this stage.
- Add milk and season. Pour in 2 cups whole milk while whisking to avoid lumps. Stir in 1 teaspoon Dijon mustard, ¼ teaspoon nutmeg, and a pinch of salt and pepper. Simmer for 4–5 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon.
- Incorporate the cheeses. Reduce heat to low and fold in 1½ cups grated Irish sharp cheddar and ½ cup grated Gruyère. Stir until both cheeses melt completely, creating a glossy, velvety sauce. Taste and adjust seasoning if needed.
Combining & Baking
Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the drained pasta with the cheese sauce, ensuring every elbow is evenly coated. Transfer the mixture to a greased 9‑x‑13‑inch baking dish. For the topping, mix ½ cup panko breadcrumbs, 1 tablespoon melted butter, and 1 tablespoon grated Parmesan until crumbly, then sprinkle evenly over the surface.
Place the dish in the oven and bake for 20 minutes, or until the topping turns golden brown and the sauce bubbles at the edges. For an extra crisp crown, switch to broil for the final 2 minutes, watching closely to avoid burning.
Finishing Touches
Remove the mac & cheese from the oven and let it rest for 5 minutes. This short rest allows the sauce to set, making serving cleaner. Garnish with a sprinkle of fresh chives or a light drizzle of extra Guinness if you love an added punch. Serve hot, straight from the dish, and enjoy the comforting, yet sophisticated flavors.
Tips & Tricks
Perfecting the Recipe
Use a good stout. A dry Irish stout like Guinness provides the right balance of bitterness and malt; avoid overly sweet or heavily roasted beers that can overwhelm the sauce.
Grate cheese fresh. Freshly grated cheddar melts smoothly, whereas pre‑shredded cheese contains anti‑caking agents that can make the sauce grainy.
Don’t over‑cook the pasta. Al dente noodles retain texture after baking; over‑cooked pasta becomes mushy when combined with the sauce.
Season in layers. Add a pinch of salt at each stage—roux, sauce, and final bake—to build depth without oversalting.
Flavor Enhancements
For an extra lift, stir in a splash of heavy cream just before the cheese melts; this enriches the mouthfeel. A teaspoon of smoked paprika adds a subtle smoky nuance that echoes the stout’s character. Finally, finish with a handful of chopped fresh parsley for color and a hint of herbaceous freshness.
Common Mistakes to Avoid
Skipping the roux can result in a watery sauce that never thickens properly. Also, adding the cheese over high heat causes it to seize, producing a gritty texture; always melt cheese on low heat and stir gently. Lastly, neglecting the resting time leads to a runny dish that slides off the plate.
Pro Tips
Finish under the broiler. A 2‑minute burst of high heat creates the ultimate crunchy crust without over‑baking the interior.
Use a kitchen scale. Precise cheese measurements keep the sauce balanced and prevent it from becoming overly salty.
Reserve a cheese topping. Sprinkle a small amount of extra cheddar on top before baking for an extra melty layer beneath the breadcrumbs.
Make ahead, bake later. Assemble the dish up to the topping stage, refrigerate uncovered, then bake when ready; this keeps the crust crisp.
Variations
Ingredient Swaps
Swap elbow macaroni for cavatappi or shells to capture more sauce. Replace Irish cheddar with a blend of sharp white cheddar and smoked cheddar for a different flavor profile. For a richer sauce, use half heavy cream instead of milk, or add a splash of caramelized onion jam for sweet‑savory depth.
Dietary Adjustments
For gluten‑free, use certified gluten‑free pasta and substitute the flour in the roux with rice flour or cornstarch. To make it dairy‑free, swap butter for vegan margarine, milk for oat or almond milk, and use a plant‑based cheddar alternative. Keto eaters can replace pasta with spiralized cauliflower and use almond flour for the topping.
Serving Suggestions
Pair the mac & cheese with a crisp green salad dressed in a light vinaigrette to cut through the richness. Roasted root vegetables or a simple garlic‑sautéed spinach add color and nutrition. For a festive touch, serve alongside a pint of the same Guinness used in the sauce.
Storage Info
Leftover Storage
Allow the mac & cheese to cool to room temperature, then transfer to an airtight container. Refrigerate for up to 4 days. For longer keep, portion into freezer‑safe bags, squeeze out excess air, and freeze for up to 3 months. Thaw overnight in the fridge before reheating for best texture.
Reheating Instructions
Preheat the oven to 350°F (175°C), cover the leftover portion with foil, and bake for 15–20 minutes until heated through. Stir halfway and add a splash of milk or extra Guinness to revive the sauce. In a microwave, heat on medium power for 2 minutes, stir, then continue in 30‑second bursts until hot.
