Costa Cheese triangles (UK Price, Calories & Allergens 2026)
I picked up Cheese Triangles from a Costa inside a supermarket while grabbing a quick savoury bite before heading back out. The seating area was busy, so I treated it more like a takeaway snack than something to sit down with.
Cheese Triangles are a simple grab-and-go savoury food pick rather than a full hot meal. In the UK, they cost £2.50, weigh 79g per portion and come in at 190kcal, so they sit more in light snack territory than proper lunch territory.
They’re suitable for vegetarians, but they’re not suitable for vegans. The key allergens to know are wheat, barley, oats and milk.

Do Cheese Triangles work as a quick Costa lunch?
Cheese Triangles make most sense when you want something savoury, tidy and quick. The 79g portion tells you a lot: this isn’t trying to be a full lunch plate. It’s closer to a light lunch-style bite, especially if you’re eating on the move or don’t want anything awkward to handle.
At 190kcal, they’re on the lighter side for a Costa food order. That can be a plus if you only want something small, but it also means you shouldn’t expect them to carry you through a long afternoon on their own.
What actually drives the flavour here?
The Cheese Triangles ingredients are straightforward: oatmeal bread, reduced fat cheese and reduced fat soft cheese. The flavour direction is exactly what the name suggests: bread and cheese, without lots of extra fillings competing for attention.
The oatmeal bread includes wheat, pinhead oatmeal, wheat bran and malted barley flour, so the bread base is more than plain white bread on paper. The cheese and soft cheese are the main savoury drivers, and both contain milk.
The nutrition numbers that help you decide
Cheese Triangles nutrition is fairly easy to read because the portion is small. Each portion has 190kcal, 25g carbohydrates, 10g protein, 4.7g fat and 2.5g fibre. The protein is useful for a snack-sized savoury order, but the portion weight still keeps it firmly in lighter territory.
The sugars are low at 2g per portion. Salt is 0.78g, which is worth noticing if you’re choosing between a sweet bakery item and a savoury cheese-based snack. Saturates are 2.4g per portion, coming mainly from the cheese ingredients.

Snack, light lunch or proper meal?
Cheese Triangles are best viewed as a snack or light lunch-style Costa food item. If you’re after a simple savoury bite, they do the job without feeling like a sweet treat or a hot meal.
If your lunch needs to feel more substantial, the 79g portion and 190kcal count may feel a bit modest. If you’re grabbing something before travelling, between errands or alongside another Costa item, the convenience is the main reason to choose them.
Where the allergens need your attention
Cheese Triangles allergens are clear: they contain wheat, barley, oats and milk. That matches the oatmeal bread and cheese-based filling.
They’re suitable for vegetarians, so the answer to “are Cheese Triangles vegetarian?” is yes. The answer to “are Cheese Triangles vegan?” is no, because the ingredients include milk-based cheese and soft cheese.
My honest pick
Order Cheese Triangles if you want a simple, low-fuss savoury snack from Costa and you’re happy with a lighter portion. For £2.50, the 79g serving and 190kcal count make sense as a quick bite rather than a main meal, with 10g protein giving them a bit more usefulness than a purely bread-based snack. They fit the kind of supermarket Costa takeaway situation from the opening: quick, portable and easy to order. Skip them if you want a bigger lunch, a hot meal, or anything vegan. Also avoid them if wheat, barley, oats or milk are an issue for you.
