How to Make a Cheese and Red Onion Sandwich
A cheese and onion sandwich is a British classic. Here I show you the easiest and most delicious way to make it at home!
For those of you in the UK, this tastes JUST like ones you get from the supermarket (dare I say, better 😬). For everyone else just follow me. You're gonna love it…
Cheese and Onion Sandwich Filler
I know, can you really get much more of a pungent combo? 🤣 It's gotta be done though. Here's what you're gonna need:
- Cheese – 50/50 combo of Cheddar and Red Leicester (or more cheddar, preferably red).
- Onion – Red Onion and Spring Onion. Both VERY finely diced.
- Mayo – Whole egg & full fat of course. No healthy subs for this!
- Black Pepper – A good pinch of freshly cracked black pepper works wonders in this.
Can I make this ahead of time?
If you want to save time between you crying over the chopping board from the onions and actually eating the sandwich, you can absolutely make the filling ahead of time. Just tightly seal in the fridge until needed.
Process shots: add all filling ingredients to a bowl (photo 1), stir with spatula then check for seasoning and adjust accordingly (photo 2).
Cheese and Onion Sandwich
When it comes to making the sandwich, as you can imagine it truly couldn't be easier!
What bread to use?
Classically some form of seeded/wholemeal bread is used. However it's not a deal breaker if all you have is white bread. In all cases just make sure it's soft (not toasted) and in medium slices.
Let there be butter!
Certainly don't forget the butter here. It not only adds a mild bit of flavour, but also prevents the mayo from seeping into the bread.
Process shots: slice bread (photo 1), spread with butter (photo 2), divide filling (photo 3), top with more buttered bread and slice diagonally (photo 4).
Serving a Cheese and Onion Sandwich
- Crisp/Chip Recommendation: Salt & Vinegar, always and forever.
- Side Recommendation: This works great as part of a soup and a sandwich. Roasted Tomato Soup is perfect!
Alrighty, let's tuck into the full recipe for this cheese and onion sandwich shall we?!

-
Medium Sized Mixing Bowl & Spatula
-
Sharp Knife & Chopping Board
-
Cheese Grater
- 8 medium slices of Seeded Bread
- 1 cup / 100g Cheddar, grated
- 1 cup / 100g Red Leicester, grated (or more cheddar, preferably different colour)
- 2/3 cup / 160g Mayonnaise (Whole Egg, Full Fat)
- 1/2 cup / 2oz / 60g Red Onion, very finely diced/minced (or other sweet onion)
- 2 large / 1.4oz / 40g Spring/Green Onion, very finely diced
- Butter, as needed
- pinch of Cracked Black Pepper, to taste
-
In a medium sized mixing bowl add cheese, onion, spring onion, mayo and a good pinch of cracked black pepper. Give it a good stir, then test for seasoning and adjust accordingly.
-
Spread one side of all of your slices of bread with butter. Divide filling among 4 of those slices (spread right to the edges). Top with second slice of buttered bread, cut diagonally and enjoy!
a) Subs - The above combo, in my opinion, is pretty much identical those cheese and onion sandwiches you get from the supermarkets. As such, I don't recommend making any big subs (i.e yogurt or sour cream with or instead of mayo, different cheeses etc). Small subs like bread are fine.
b) Make Ahead - Feel free to make the fillings ahead of time! Just tightly cover in the fridge for 4-5days.
c) Calories - based on using 8 tsp butter in total, then per sandwich:
