This upscale quiche is great for company. Read the section on blind-baking the crust a few times before you get started; it’s the trickiest part (but by no means hard). The only special equipment you’ll need is a 10 1/2-inch tart pan with a removable bottom. Once you have one of these, you’ll use it for a hundred different things, so it’s a good investment.
Cooks' Note
To roast the garlic, bang the garlic head on the counter to loosen the cloves. Put the separated cloves in a piece of aluminum foil, drizzle with olive oil, and close up the pouch. Bake for 30 minutes (you can bake them with the tart shell). The garlic should be soft.
