Frequently asked questions
How long can I store leftovers?
Mille-feuille can be stored in the refrigerator for up to 2 days, though it is best enjoyed fresh due to the pastry's tendency to soften.
Can I make this ahead?
Yes, you can prepare the pastry cream and ganache in advance, but assemble closer to serving time.
What can I use for a gluten-free version?
Substitute with a high-quality gluten-free flour blend for the dough.
Can I use milk chocolate for the ganache?
Absolutely, but it will result in a sweeter finish, so adjust sugar as needed.
Is it possible to freeze the components?
The dough can be frozen, but thaw it completely in the fridge before rolling. Avoid freezing assembled mille-feuille.
