Ingredients

2 prepared 9-inch pie crusts

3 tbsp Sizzle

2 large yellow onions, sliced

3 cloves of garlic, minced

1-1½ lbs baby bella mushrooms, sliced

3 leeks, sliced into discs

¼ cup all-purpose flour

1 cup broth; vegetable, chicken, or beef-your preference

¼ cup half and half

½ cup Parmesan cheese, grated

2 cups lightly packed baby spinach, roughly chopped 

2 tbsp fresh thyme leaves

Kosher salt and freshly ground pepper, to taste 

1 large egg + 1 tbsp water, slightly beaten for an egg wash

Instructions

Active Time: 40 Minutes

Full Time: 1 Hour

Serves 8
1

In a large skillet, over medium-low heat, add Sizzle. Add onions, stirring occasionally and cook until golden brown and caramelized, about 30 minutes. Add garlic and cook until fragrant, about 1 minute. 

2

Stir in mushrooms and leeks, cooking until their juices release and the vegetables begin to soften, about 5 minutes. Sprinkle the flour over the mushroom-onion mixture, allowing the dry flour coating to dampen, about 1 minute. Slowly add the broth and half & half, stirring until the mixture thickens, about 2 minutes. Remove from heat, stir in thyme, then spinach until wilted, followed by the Parmesan, about 1-2 minutes. 

3

Salt and pepper the filling mixture to taste. Let cool completely. 

4

Preheat oven to 400F and line a baking sheet with parchment paper. 

5

While your filling is cooling, place the bottom crust-dough in a 9-inch pie plate, trimming to leave about 2-inches of overhang from the plate's edge. Scoop the cooled filling into the pie crust and then cover with the top crust-dough, folding over the edges and tucking under itself to ensure the pie is sealed on all sides. Crimp decoratively around the perimeter. Using a small knife, make a few slits/vents into the pie top so the steam can release as it bakes. Brush the top with egg wash.

6

Bake the assembled pie for 20 minutes. Reduce oven to 375F baking until the crust is golden brown. Remove from the oven and cool for 10 minutes. 

7

Serve warm with a side salad using Drizzle and a preferred vinegar or lemon juice.
