Be sure to follow the puff pastry package instructions! Cut off the root & dark green leaves of the leek. Slice the leek in half lengthwise, then into thin slices. Rinse the leek in a colander. Drain thoroughly.

Melt a dab of butter in a pan over medium-high heat. Add the drained leeks. Season with salt & pepper. Sauté for 2 min.

Step 3
Reduce the heat to low, cover & simmer for 5-7 min.

Preheat the oven to 400°F. Clean & slice the mushrooms.


Step 5
Melt 2 tbsp of butter (per pot pie) in a pot over medium heat. Add the flour. Whisk constantly until combined.

Step 6
Add the milk in thirds, whisking between each addition. The mixture should be smooth & creamy. Season with salt & pepper. Continue stirring.

When the sauce starts to thicken, add the shredded cheese. Stir & turn off the heat.


Step 8
Add the cooked leeks & raw mushrooms to the sauce. Stir again.
