Top Tips

Eating for one?

Make the lasagne in smaller portions and freeze before cooking. Cook from frozen for 45–60 minutes until piping hot.

Fancy leftovers?

Store in the fridge for up to 4 days.
Cooking, cooling and reheating pasta increases resistant starch, which can support gut health and blood sugar control.

Want some variety?

When following the healthy lasagne recipe, make a double batch of the Bolognese and turn it into:

• Spaghetti Bolognese
• Chilli con carne
• Stuffed peppers
