Greggs How-To Guides

Practical guides on freezing, reheating, fridge shelf-life and crisping Greggs pastry.

Most Greggs savouries are bought to eat straight away, but many end up in the fridge or freezer. These guides cover what to do next, following UK Food Standards Agency advice on storing and reheating cooked food.

The reheating guide gives air fryer, oven and microwave times for sausage rolls and bakes from chilled and frozen. The freezing guide explains how to wrap them, how long they keep and how to defrost them. The bake-at-home guide covers the frozen Greggs range sold at Iceland, with the on-pack cooking time we verified.

Each guide answers one question in depth, so the freezing answers live in the freezing guide and the reheating answers in the reheating guide.

Frequently asked questions

How do you reheat a Greggs sausage roll?

Air fryer at 180°C for 6–8 minutes, or oven at 190°C (170°C fan) for 10–12 minutes, until piping hot. See our reheating guide for frozen times and microwave tips.

Can you freeze Greggs sausage rolls?

Yes. Cool them, wrap each one, seal them in a freezer bag and eat within one to two months for the best pastry. Our freezing guide has the full method.
