A bacon sandwich is an everyday concept in the UK, most often enjoyed at breakfast, where the bacon takes centre stage rather than being a side character. At its core, a bacon sandwich is a simple yet glorious creation: slices of bacon placed between two pieces of bread.
That’s the essence, but as with many seemingly straightforward things, the nuances make all the difference.
The Bread Debate
Does it have to be white bread? Many purists would argue yes, and a soft white slice certainly complements the bacon’s saltiness. However, brown bread is perfectly acceptable for a healthier twist, and let’s not forget the option of a bread bun. In this case, it’s no longer a bacon sandwich but a bacon roll, yet it retains all the same charm.
Some prefer toasted bread for a bit of crunch, while others dip their bread in the fat left from cooking the bacon—a rich indulgence that’s not for the faint-hearted. Buttering the bread is another point of contention. For some, butter is essential yet for others, it’s a step too far when the bacon provides enough moisture.
The Bacon
Here’s where the choices expand. Do you go for back bacon or streaky bacon? Smoked or unsmoked? Streaky bacon, with its higher fat content, crisps up beautifully when cooked, especially when grilled, which is my preferred method as the fat melts away. Back bacon, on the other hand, offers a meatier bite.
Some love their bacon crispy, while others prefer it softer and less cooked. There’s also the choice between frying and grilling. Frying gives you the option to keep the rendered fat for cooking other things (or for dipping your bread, as mentioned), while grilling is a leaner option.
Sauce or No Sauce?
This is where debates can become heated. A bacon sandwich is rarely complete without some sort of condiment, and in the UK, the classics are red or brown sauce.
- Red sauce refers to tomato ketchup, with Heinz being the gold standard for many. It’s sweet and tangy, perfectly offsetting the savoury bacon.
- Brown sauce, typically HP Sauce, is rich, tangy, and slightly spicy, with a base of meat stock and vinegar. It’s a quintessentially British choice.
Of course, there are outliers. Some might opt for BBQ sauce, or like me, mayonnaise—especially if you’re adding extras like lettuce and tomato to transform your sandwich into a BLT.

The Extras
Speaking of BLTs, some might scoff at the idea of adding vegetables to a bacon sandwich, especially if it’s being consumed for breakfast, which is its most common setting. However, a slice of fresh tomato and a bit of crisp lettuce can elevate your bacon sandwich to something altogether more refined.
Then there’s the fried egg. Add one to your bacon sandwich, and you’ve entered another realm entirely. A runny yolk that oozes out with each bite creates what the military affectionately call an “egg banjo.” Why? Because when the yolk inevitably drips onto your uniform, you’ll instinctively hold your sandwich with one hand while “strumming” your chest with the other, trying to clean up the mess.
A British Institution
In the UK, the bacon sandwich is more than a meal; it’s a comforting ritual, often associated with lazy weekends, quick breakfasts, or a hearty snack after a long day. The magic often begins with the unmistakable and irresistible smell of bacon sizzling in the pan, filling the air with a promise of satisfaction and indulgence.
While Americans have their own bacon traditions—often crispy and paired with pancakes or eggs—the British bacon sandwich is a world unto itself, defined by its flexibility and personalisation.
Whether you like it simple or fully loaded, a bacon sandwich is a celebration of salty, smoky, savoury goodness. So, how do you take yours?

Ah don’t forget about calling it a ‘bacon butty’ too, especially if you are in the north!
Of course, I mustn’t forget that!
My one and only was in Lincolnshire. I remember the bacon, and egg, and a homemade bun – but no sauce – but whether there was butter or not I don’t remember. Pretty sure there wasn’t tomato or lettuce. Probably streaky bacon, but not too thin. Anyway – it was so delicious I wanted to order another, but I think we were full. Better go back and get one!
Lovely, and in Lincolnshire they also have great sausages!
My favorite bacon sandwich would be the blt with miracle whip on soft white bread! But in a pinch have had just bacon and miracle whip, also adding an egg is a great breakfast treat but on toasted bread!
You cannot go wrong with Bacon any which way!
Thank you, Cathy. I had to look up miracle whip but I see it is mayonnaise. And maple syrup – lovely!
My grandmother had a different take on this. She made bacon rolls for packed lunches on long trips. Where things strayed from the beaten path was that she lightly buttered her homemade buns, like one would a tea sandwich, and then she used yellow “hot dog”-style mustard for the sauce. It was generally Heinz mustard (My family comes from about 90 minutes north of Pittsburgh, Pa., where H.J. Heinz got its start), so it would not have been because ketchup was hard to come by. Where she still with us, she would be about 115 now.
That’s a wonderful story. Thank you.
Thank you for answering my question! All of the options sound delicious, but crispy bacon on soft white bread is what I need to try first! Bacon makes everything better.
Sorry it took so long to reply, but it was a fun post to write with lots of readers comments and responses. I hope you get to try one at some point!
In America, we eat bacon at any meal! BLTs are a favorite summer treat with tomatoes and lettuce fresh from the garden. People will argue about the brand of mayonnaise. Here in the South, Duke’s Mayo is as close to homemade taste as you can find. Adding a slice of sharp cheddar to your bacon sandwich is also yummy. (Today we had bacon on the side with our Mac and cheese!)
Oh, yes. Cheese is an added luxury!
Bacon Butties were a staple in my house growing up. My dad, being from Shildon in County Durham, probably had something to do with that. I see a lot of people commenting about putting mayo on theirs, while I don’t put mayo on mine, I do spread a little bit of Heinz Salad Cream on mine, and it’s delicious mind you I use it to replace mayo in a lot of things.
