Calories in Starbucks Cheese & Mushroom Croissant come to 324 per piece, and I didn’t expect this one to have almost zero sugar, but it doesn’t — just 4.4g, which makes it stand out on a menu dominated by sweet pastries. With 13g of protein, it’s more of a savory lunch option than a coffee companion, and the 508mg of sodium reflects that too.
Fat is on the higher side at 19g, with 12g saturated, mostly from the cheese filling and buttery lamination. It’s vegetarian, but contains wheat, milk, and egg, so it’s not for anyone avoiding dairy or gluten.
If you want something sweeter from the croissant lineup, the Chocolate & Hazelnut Croissant is the obvious pick, and the Fruit Scone is a lighter alternative if you’re not after cheese at all.
