One pie crust at room temperature
2 tablespoons Dijon mustard
1/2 pound bacon, cut into 1 inch chunks
1 large shallot, diced
1/2 cup milk
2 cups shredded cheddar cheese
Preheat oven to 425 degrees. Place pie crust into pie pan, pressing firmly on the bottom and sides. Form the edges into a raised crust - flute if you'd like. Place a square of parchment or waxed paper over the pie crust and fill with dried beans, rice or pie weights if you have them. Cover the edge with a pie ring or foil. (Also, DON'T use foil to line the pie crust with its weights. It tends to stick.) Slide the pie crust into the oven on the middle-lower rack and bake for 20 minutes or until golden brown. Leave the oven at 425 degrees and set the pie crust somewhere so it can cool a bit. When it's cool, remove the parchement and weights. Spread Dijon over the cooled crust.
In a heavy-bottomed skillet, brown the bacon over medium heat until crispy. Drain fat off as needed. I find it gets crispier if you take out some of the extra fat. Scoop out bacon bits onto a paper towel on a plate.
Turn the heat down a tad. Add shallots to the pan with the bacon fat, stirring often to prevent burning. Cook for 5 minutes or so. Remove from pan into a bowl or plate (they can share with the bacon, if you want) so they cool off some.
In a medium mixing bowl, beat the eggs until thoroughly mixed, then add milk and whisk until combined. Add the cheese, bacon and shallots to egg mixture. Carefully pour egg mixture into prepared pie crust.
(The crust here is a little darker than I wanted because I *forgot* to cover the edge in the first baking. Do as I say, not as I do.)
Cover the edge with the pie ring or foil. Place in the 425 degree oven and bake for 20 minutes. Check for doneness by inserting a toothpick into the center. I usually have to bake it another 5 minutes or so, but ovens vary.
**Edit: My mom helpfully pointed out that I didn't include any seasonings. Well, duh, I did add a teaspoon of salt and a generous amount of pepper. I neglected to include that, so, sorry. ADD SALT AND PEPPER.
