3 slices slab or regular bacon, cut into 1/4-inch pieces (1/2 cup)
2 garlic cloves, minced (2 teaspoons)
1 medium onion, thinly sliced (1 cup)
1 tablespoon unsalted butter
3 cups thinly sliced white or cremini mushrooms (10 ounces)
Coarse salt and freshly ground pepper
2 tablespoons heavy cream
1 teaspoon Dijon mustard
Pate Brisee for Mushroom-and-Bacon Tart
All-purpose flour, for surface
2 plum tomatoes, sliced 1/4 inch thick
3 ounces sharp cheddar cheese, coarsely grated (3/4 cup)
1 large egg, lightly beaten, for egg wash

Steps:

Preheat oven to 375 degrees. Cook bacon in a skillet over medium heat until crisp, about 8 minutes. Using a slotted spoon, transfer to a bowl. Add garlic and onion to skillet. Cook until onion is translucent, about 5 minutes. Add to bacon.
Return skillet to heat, and melt 1/2 tablespoon butter. Add 1 1/2 cups mushrooms and 1/4 teaspoon salt, and cook until golden on edges and softened, about 5 minutes. Transfer to a plate. Repeat with remaining 1/2 tablespoon butter and 1 1/2 cups mushrooms. Stir cream and mustard into last batch in skillet, and cook for 30 seconds. Add to bacon-onion mixture, along with first batch of mushrooms. Let cool.
Roll out pate brisee to a 12-by-18-inch rectangle (about 1/8 inch thick) on a lightly floured surface. Transfer to a parchment-lined baking sheet. Spread mushroom-bacon mixture over dough, leaving a 3-inch border. Tuck tomatoes into filling, leaving some poking out. Sprinkle with cheddar. Fold in edges to form a 6-inch-wide open-topped crust; brush crust with egg wash. Bake until golden brown and center is bubbling, about 55 minutes. Serve warm or at room temperature.
