Big Arch® with Bacon Ingredients
Beef Patties
The burger features two patties made from 100% pure British and Irish beef. McDonald’s doesn’t use fillers, preservatives, or flavour enhancers—only quality beef seasoned with salt and pepper after cooking.
Poppy & Sesame Seed Bun
The bun is made with enriched wheat flour, sesame seeds, poppy seeds, rapeseed oil, yeast, and natural flavourings, giving it a soft texture with a light crunch from the seeds.
White Cheddar Cheese
Creamy white cheddar cheese slices add a rich, savoury flavour that pairs perfectly with the beef and bacon.
Big Arch Sauce
The signature Big Arch Sauce combines tomato purée, rapeseed oil, egg yolk, mustard, vinegar, spices, lemon juice concentrate, and natural flavourings to create a creamy, tangy burger sauce exclusive to this sandwich.
Bacon
Smoky streaky bacon adds extra flavour and a satisfying crispy texture.
Fresh Vegetables
The burger is finished with:
- Iceberg lettuce
- Crispy onions
- Fresh white onions
- Pickle slices
These ingredients balance the richness of the beef with freshness and crunch.
Allergen Information
The Big Arch® with Bacon contains the following allergens:
- Wheat (bun and crispy onions)
- Milk (white cheddar cheese)
- Egg (Big Arch Sauce)
- Mustard (Big Arch Sauce)
- Sesame (bun)
Because McDonald’s prepares food in shared kitchens, cross-contact with other allergens may occur. Although ingredients can be removed upon request, McDonald’s cannot guarantee that any menu item is completely allergen-free.
Big Arch Sauce Explained
One of the highlights of this burger is the exclusive Big Arch Sauce. Unlike the famous Big Mac® Sauce, this recipe has a richer, creamier texture with a slightly tangy finish. Made using tomato purée, mustard, egg yolk, vinegar, and a blend of seasonings, it complements the double beef patties without overpowering the other ingredients.
Big Arch® with Bacon Review
The Big Arch® with Bacon is designed for customers who enjoy large burgers with bold flavours. The double beef patties provide a juicy base, while the smoky bacon and creamy white cheddar add richness. Meanwhile, the crispy onions contribute extra crunch, and the Big Arch Sauce brings everything together with its smooth, tangy flavour.
Although it’s one of the highest-calorie burgers on the McDonald’s UK menu, it’s also one of the most satisfying. If you’re looking for a filling limited-time burger, the Big Arch® with Bacon is well worth trying.
Big Arch® with Bacon vs Big Mac®
Although both burgers feature two beef patties, they’re quite different.
| Big Arch® with Bacon | Big Mac® |
|---|---|
| Larger beef patties | Smaller beef patties |
| White cheddar cheese | Processed cheese |
| Includes bacon | No bacon |
| Big Arch Sauce | Big Mac® Sauce |
| Crispy onions | Diced onions |
| 1103 kcal | Lower calories |
| Limited Time Only | Permanent menu item |
If you want a bigger, meatier burger with bacon and cheddar, choose the Big Arch® with Bacon. However, if you prefer the iconic McDonald’s classic, the Big Mac® remains a favourite.
