It’s also surprisingly versatile. You can enjoy it as a main course for an Irish dinner or as a side dish alongside roasted meats or vegetables.

Ingredient List

For the Pasta

• 12 oz elbow macaroni (about 3 cups)
• 1 tsp salt (for boiling water)

For the Cheese Sauce

• 3 tbsp unsalted butter
• 3 tbsp all-purpose flour
• 2 cups whole milk
• 1 cup heavy cream
• 1 cup Guinness stout
• 2 cups sharp cheddar cheese, shredded
• 1 cup Gruyère cheese, shredded
• ½ tsp mustard powder
• ¼ tsp smoked paprika
• Salt and pepper, to taste

For the Topping

• 1 cup panko breadcrumbs
• 2 tbsp unsalted butter, melted
• ¼ cup Parmesan cheese, grated
• Fresh parsley, chopped (optional, for garnish)

Ingredient Notes

• I always use sharp cheddar—it melts beautifully and packs that classic cheesy punch.
• Gruyère adds a nutty, slightly sweet flavor that pairs so well with the Guinness. Don’t skip it!
• Guinness is the star here—it gives the sauce a subtle bitterness that balances the richness of the cheese. Use a good quality stout for the best flavor.
• Panko breadcrumbs make the topping wonderfully crunchy. Regular breadcrumbs work, but panko gives it that golden, airy texture.
• A pinch of smoked paprika adds warmth and depth—trust me, it makes a difference!

Kitchen Equipment Needed

• Large pot – for boiling the pasta. I love using my heavy-bottomed pot; it keeps water from boiling over.
• Medium saucepan – to make the cheese sauce. A nonstick pan works great to prevent sticking.
• Whisk – for smooth, lump-free sauce. I always keep a sturdy silicone whisk on hand.
• Baking dish (9×13 inch) – to bake the mac and cheese. Glass or ceramic works best for even browning.
• Mixing spoon – for stirring everything together. Wooden or silicone both work.
• Measuring cups and spoons – for accurate ingredients. I never skip this step—it keeps the sauce perfectly balanced.
• Oven mitts – to safely handle the hot baking dish. Safety first, always!

Instructions

Step 1: Cook the Pasta

1. Bring a large pot of salted water to a boil.
2. Add the elbow macaroni and cook according to package directions until just al dente.
3. Drain the pasta and set aside.
   Pro tip: Reserve ½ cup of the pasta water—it can help loosen the sauce later if it’s too thick.

Step 2: Make the Cheese Sauce

1. In a medium saucepan over medium heat, melt the butter.
2. Once melted, whisk in the flour to make a smooth roux. Cook for 1–2 minutes until slightly golden.
   Pro tip: Whisk continuously to prevent lumps and achieve a silky base.
3. Gradually add the milk and cream, whisking constantly until the mixture thickens slightly.
4. Slowly pour in the Guinness, stirring to combine. The sauce should be smooth and glossy.
5. Lower the heat and stir in the shredded cheddar and Gruyère cheese, one handful at a time.
6. Add mustard powder, smoked paprika, salt, and pepper. Taste and adjust seasoning.

Step 3: Combine Pasta and Sauce

Step 5: Bake to Golden Perfection

1. Preheat your oven to 375°F (190°C).
2. Bake the mac and cheese for 20–25 minutes, until the topping is golden and crispy.
3. Remove from the oven and let it rest for 5 minutes before serving.
   Pro tip: Garnish with chopped parsley for a fresh pop of color and flavor.

Tips and Tricks for Success

• Don’t overcook the pasta – Slightly firm noodles hold up better in the creamy sauce and prevent mushy mac and cheese.
• Whisk the roux carefully – Continuous whisking when adding milk and Guinness keeps the sauce smooth and lump-free.
• Add cheese gradually – Stir in cheese in small handfuls so it melts evenly and stays creamy.
• Use quality Guinness – The flavor of the stout really shines through; a good-quality Guinness makes a noticeable difference.
• Let it rest before serving – Giving the mac and cheese 5 minutes after baking helps the sauce thicken slightly and makes serving cleaner.

Ingredient Substitutions and Variations

• Cheese options – Swap Gruyère for Fontina or mozzarella for a different melt and flavor profile.
• Milk alternatives – Whole milk can be replaced with half-and-half or 2% milk; just reduce the cream slightly for balance.
• Beer swap – If you don’t have Guinness, a dark ale or porter works, though the flavor will be slightly sweeter.
• Add-ins – Stir in cooked bacon, caramelized onions, or sautéed mushrooms for an extra layer of flavor.
• Spice it up – Add a pinch of cayenne or a few dashes of hot sauce to the cheese sauce for a gentle kick.

Serving Suggestions

• I love serving this Guinness Mac and Cheese with a simple green salad and a drizzle of olive oil—it balances the richness perfectly!
• Pair it with roasted vegetables like Brussels sprouts or carrots for a colorful, hearty Irish dinner.
• For a St Patrick’s Day Mac and Cheese twist, serve alongside corned beef or Irish sausages to make it festive and filling.
• It’s amazing on its own as a cozy weeknight dinner, with a slice of crusty bread to scoop up every cheesy bite.
• Top individual servings with extra parsley and a sprinkle of Parmesan—it adds freshness and a little crunch that everyone loves.

Storage and Reheating Instructions

• Refrigerate: Store leftovers in an airtight container for up to 3–4 days.
• Freeze: For longer storage, freeze in a freezer-safe dish for up to 2 months. Let it thaw overnight in the fridge before reheating.
• Reheat in oven: Cover with foil and bake at 350°F (175°C) for 15–20 minutes until warmed through.
• Reheat on stove: Place in a saucepan over low heat, stirring occasionally. Add a splash of milk to loosen the sauce if needed.
• Reheat in microwave: Heat in short intervals, stirring between each, until evenly warmed.

Frequently Asked Questions

Can I make this Guinness Mac and Cheese ahead of time?

Absolutely! You can prepare the cheese sauce and pasta separately, then combine and refrigerate for up to a day before baking. It saves time without sacrificing flavor.

Can I use a different type of beer instead of Guinness?

Yes! Dark ales or porters work well too, though they will give a slightly sweeter flavor. Avoid very hoppy beers, as they can be bitter and overpower the cheese.

Can I make this recipe vegetarian?

Definitely! Simply skip any meat add-ins and keep it focused on the pasta, cheese, and Guinness. You’ll still get a rich and satisfying dish.

How do I get a crispy topping without burning the cheese?

Mix the panko with melted butter and Parmesan for even browning, and bake at 375°F (190°C). Cover with foil for the first 10 minutes if your topping browns too quickly.

Can I make it gluten-free?

Yes! Use gluten-free pasta and substitute the all-purpose flour in the roux with a gluten-free blend. The sauce may be slightly less thick but still delicious.

How should I reheat leftovers for best results?

Oven reheating works best—cover with foil and bake at 350°F (175°C) until warmed through. Add a splash of milk if the sauce has thickened too much.
