Preheat your oven to 350°F and get out a medium-sized rimmed baking sheet.
Cook the bacon in a skillet on the stovetop. Once cooked, dice into small pieces.
Whisk the eggs, half and half, salt, and pepper together in a medium-sized mixing bowl.
Spread the broccoli out into an even layer at the bottom of your pie crust.
Top the broccoli with an even layer of cooked bacon pieces.
Sprinkle the shredded cheese over top of the broccoli and bacon.
Place the pie crust on the baking sheet. The egg filling will reach the top of the crust. The baking sheet will catch any spills and make transferring the quiche in and out of the oven much easier.
Slowly pour the egg mixture into the pie crust, over top of the broccoli, bacon, and cheese.
Carefully transfer your quiche into the oven and bake on the middle rack for 45-60 minutes at 350°F. Start checking for doneness after 45 minutes. You'll know it's cooked when the middle of the quiche is firm and a toothpick inserted into the center comes out clean.
Once cooked through, remove the quiche from the oven and let it cool for 15-20 minutes to allow it to fully set. If you slice it right away, it's likely to fall apart.
After it's cooled down slightly, slice it into pieces, serve, and enjoy!
