Yes, you can freeze Brussels sprouts. Fresh sprouts are most dependable after a brief blanch, while leftover cooked or roasted sprouts can be frozen once cooled promptly. They will be softer after freezing, so roasting, sautéing, soups and hearty side dishes are usually better uses than serving them plain.

Step-by-step method
- Choose firm sprouts, discard damaged outer leaves and trim the stem ends.
- Halve larger sprouts so they cook evenly, leaving small sprouts whole if preferred.
- Blanch fresh sprouts briefly in boiling water, then cool them quickly in cold water.
- Drain and dry them very well before freezing so excess water does not turn to ice.
- Freeze in labelled meal-sized bags or containers; freeze flat where possible.
- Roast or sauté fresh-frozen sprouts from frozen, or reheat cooked portions until piping hot.
Do you need to blanch Brussels sprouts before freezing?
For fresh sprouts, blanching is the most reliable option because it helps them keep a better colour and texture. Cooked or roasted leftovers can be cooled and frozen without blanching.
Can you freeze roasted Brussels sprouts?
Yes. Cool them promptly, pack in airtight portions and reheat in a hot oven or frying pan. Expect them to be softer than freshly roasted sprouts.
How do you stop frozen sprouts going soggy?
Dry blanched sprouts thoroughly, avoid overfilling bags, and cook them from frozen in a hot oven or pan rather than letting them sit at room temperature.
