- 2 Tbsp butter
- 1 large leek (white and light green parts only) thinly sliced
- 1 clove garlic minced
- 1/2 cup heavy cream
- 3/4 cup whole milk
- 1 1/2 tsp salt
- 1/4 tsp black pepper
- 1/4 tsp paprika
- 3 large russet potatoes peeled and thinly sliced
- 1 1/2 tsp fresh thyme
- 1/2 cup cheddar cheese grated
- 1/4 cup parmesan cheese shaved
Garnishes
- chopped chives
- pinch or two of paprika
Preheat your oven to 375 degrees Fahrenheit. Lightly butter a 9-inch pie dish, 9x9 inch square baking pan, or a medium size gratin dish, set aside.
In a large non-stick skillet over medium heat, melt butter, then add leeks. Sauté until soft and tender.
Then add garlic and cook until fragrant (taking care to not let either brown).
Add cream, whole milk, salt, pepper and paprika.
Bring mixture to a simmer then add the sliced potatoes into the mixture. Then stir in thyme.
Next, combine both cheeses in a small bowl.
Transfer ⅓ of the potato slices to the prepared baking dish, sprinkle with ⅓ of the cheese mixture, pour in ⅓ of the cream mixture in between each layer (over the cheese). Repeat two more times.
Place in oven and bake for 45-55 minutes or until the potatoes are tender and the top is golden brown.
Remove from the oven and allow to cool for 15 minutes before garnishing with a pinch or two of paprika and chopped chives.
This recipe can easily be doubled and baked in a 9x13" dish.
Clean Your Leek! To clean it, slice the leek down to the root, then rotate it so that the cut is even with your cutting board and cut the leek again. That will leave you with 4 even sections. Now that the leek is nice and open you can run it under cold water to remove an grit or dirt that's trapped deep down in there.
You can store this recipe in an airtight container in your fridge for 3-4 days.
To reheat this recipe you can bake in the oven at 350 degrees Fahrenheit until everything has warmed through. Or, you can heat up a serving in your microwave until everything has warmed through.
