There's absolutely no need to boil or precook the sausages for this recipe. Knacki-style sausages are already cooked during production. Simply slice them into small rounds and arrange them directly on your pastry. They will heat up and release their flavors during the 35 minutes of baking time.

What's the secret to a crispy crust in this sausage pie?

The secret to this recipe lies in the tablespoon of mustard spread on the puff pastry. Besides deliciously enhancing the flavor of the sausages, which children generally love, the mustard forms a protective layer. It seals the pastry base and prevents the milk and cream filling from making the puff pastry soggy.

How to sneak vegetables into this sausage pie?

Sausage pie is an excellent way to get even the pickiest eaters to eat their vegetables. You can easily slip a few thinly sliced ​​tomato rounds under the sausages, or add a handful of sliced ​​leeks, sautéed until softened, directly to your egg and cream mixture. The smoky flavor of the sausage will subtly mask the taste of the vegetables!
