This Oktoberfest Bacon Beer Mac combines tender elbow macaroni with a rich, creamy cheese sauce infused with lager style beer for a deep and satisfying flavor. Crispy bacon adds a smoky crunch, while Dijon mustard and garlic powder give subtle warmth and tang. Baked to a golden finish with optional breadcrumbs for extra texture and garnished with fresh parsley, this dish is perfect for cozy evenings or festive gatherings.
I first made this recipe during a small fall gathering, and it was an instant hit. It quickly became one of the dishes I look forward to making every Oktoberfest season, bringing comfort and celebration together on one plate.
Ingredients
- Elbow macaroni: choose good quality pasta that holds its shape when cooked
- Bacon: provides smoky crispness and adds depth to the dish
- Unsalted butter: used to create a smooth roux for the sauce
- All purpose flour: thickens the cheese sauce to creamy perfection
- Milk: forms the base of the sauce and adds creaminess
- Beer: preferably a lager or Oktoberfest beer brings a malty, slightly hoppy flavor that elevates the dish
- Sharp cheddar cheese: offers a sharp tang and excellent melting quality
- Gruyère cheese: adds nuttiness and a creamy texture
- Dijon mustard: brightens the sauce with subtle acidity
- Garlic powder: delivers a hint of aromatic warmth
- Salt and pepper: are essential for balancing flavors
- Breadcrumbs: optional add a crunchy topping when baked
- Fresh parsley: provides an herbaceous garnish to lighten the final plate
Instructions
- Sauté the Bacon:
- Cook the chopped bacon over medium heat until crispy. This step renders out the flavorful fat that will be used for the sauce base. Remove the bacon onto paper towels to drain while keeping the bacon grease in the skillet.
- Make the Roux:
- Add the butter to the bacon grease in the skillet and melt it over medium heat. Whisk in the flour and cook for about one minute until it turns lightly browned. This step cooks out the raw flour taste and forms a thickening base for the sauce.
- Create the Beer Cheese Sauce:
- Gradually whisk in the milk and beer together while stirring constantly to prevent lumps. Allow this mixture to thicken over about five minutes on medium heat. Then lower the heat and stir in the sharp cheddar and Gruyère cheeses until completely melted and the sauce is smooth.
- Season the Sauce:
- Add Dijon mustard and garlic powder to the cheese sauce. Taste and season with salt and pepper according to your preference.
- Combine Pasta and Sauce:
- Mix the cooked and drained elbow macaroni into half of the crispy bacon pieces. Stir in the cheese sauce until everything is well coated.
- Bake the Mac and Cheese:
- Transfer the prepared mixture to a greased baking dish. Sprinkle breadcrumbs on top if you prefer a crunchy crust. Bake in a preheated oven at 350 degrees Fahrenheit or 175 degrees Celsius for fifteen minutes or until bubbly and golden.
- Garnish and Serve:
- Remove from the oven and top with the remaining crispy bacon and fresh parsley. Serve hot for the best flavor and texture experience.

This dish always reminds me of the first time I shared it with my family during Oktoberfest celebrations. The warm, comforting meal combined with good conversation made it a cherished tradition. The balance of sharp cheddar and Gruyère is my favorite aspect because it perfectly blends creaminess with complexity, elevating standard mac and cheese into something special.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to three days. Reheat gently in the oven or microwave, covering the dish to maintain moisture. For longer storage, freeze the mac and cheese before baking, then bake it directly from frozen, adding a few extra minutes to the cooking time.
Ingredient Substitutions
You can replace elbow macaroni with cavatappi or shells as both hold sauce well. If Oktoberfest beer is unavailable, try a pilsner or another mild lager. For cheeses, Monterey Jack or fontina melt nicely but will change the flavor subtly.
Serving Suggestions
Serve this mac and cheese alongside a crisp green salad or roasted vegetables to balance the richness. A glass of the same beer used in the recipe pairs beautifully and enhances the Oktoberfest vibe.

Serve hot garnished with parsley and enjoy with a crisp salad or a glass of the beer used in the sauce.
Common Recipe Questions
- → What type of beer works best in this dish?
Lager or Oktoberfest-style beer is ideal, adding a mild maltiness without bitterness that complements the creamy cheese sauce.
- → Can I use other cheeses instead of cheddar and Gruyère?
Yes, aged cheddar increases sharpness, while substitutions like fontina or mozzarella alter texture and flavor for a different experience.
- → How do I get the bacon crispy?
Cook chopped bacon over medium heat until golden and crisp, then drain on paper towels to remove excess fat before mixing in.
- → What’s the purpose of breadcrumbs on top?
Breadcrumbs add a crunchy texture contrast that enhances mouthfeel and presentation when baked on top of the mac.
- → Can this be made spicier?
Yes, adding a pinch of cayenne pepper or smoked paprika to the cheese sauce introduces warm, subtle heat to the dish.
- → Is it possible to prepare the sauce without beer?
Beer lends depth, but substituting extra milk or broth yields a milder, creamy sauce though some characteristic maltiness will be lost.
