All Day Eggs.
An Heirloom Tomato Quiche.
Sun-sweetened tomatoes are delicious any which way you slice it, but for us, we love to enjoy their juicy pop in a tomato quiche. Add garden-fresh basil, sweet Caramelized Onions, and a shaving of Parmigiano-Reggiano and you get our favorite summer breakfast quiche. IF you have extra tomatoes in the garden try our Chicken Caprese or our Best Tomato Salad!
What Is Quiche?
Our definition of “quiche” is simply a savory pie crust (aka, pate brisse) filled with an eggy custard. For food history buffs, here’s a tasty tidbit: quiche originated in the Alsace-Lorraine region of France, and it’s most popular iteration—Quiche Lorraine—is filled with bacon, Gruyère cheese, and heavy cream. We’ve taken that classic quiche recipe and transformed it into a vegetarian celebration of all things summer. Here’s how:
- We’ve swapped quiche Lorraine’s classic bacon for umami-rich caramelized onions.
- Add summertime seasonal ingredients like juicy heirloom tomatoes and fragrant, fresh basil.
- Sprinkle with freshly grated Parmigiano-Reggiano.
How to Make Quiche
Our quiche recipe is pretty much foolproof, thanks to the fact that most of the mixing happens in your trusty food processor. Adding caramelized onions is an easy way to add tons of flavor, while still making this a vegetarian quiche recipe.
- Start by adding thinly sliced onions to a hot frying pan bubbling with butter and brown sugar and cooking down until the onion slices collapse onto themselves and take on a deep, dark mahogany hue.
- While the onions caramelize, make the quiche crust by pulsing together flour, salt, and frozen butter in your food processor. Add water at a slowwww trickle until the dough just comes together. The more water you add, the more the crust will shrink when it bakes, so less water the better.
- Layer your heirloom tomatoes, cheese, fresh basil, and sweet caramelized onions into the crust. Pour in eggs and fresh cream, and bake until the center loses its wobble!
- Serve your tomato-laden, caramelized onion quiche alongside our Simple Butter Lettuce Salad and call it breakfast well done (or dinner, if you please!).
How to Store Leftovers + Tips
Can You Freeze Quiche? Yessss!! Maybe your friend just had a baby, or your tomato plant is so weighted down with burtingly ripe tomatoes it can barely stand upright. No matter the reason, bake this egg quiche ahead of time, let completely cool, then wrap tightly in a few layers of cling wrap, and freeze. When you’re ready for a little slice, simply pop the still-frozen quiche in a preheated oven at 350°F for about 20-30 minutes, or until it is heated through.
Frittata vs. Quiche—What’s the Diff? The easiest way to remember? Quiche = crust. Frittatas typically omit the crust and heavy cream, relying mostly on the eggs.
- Store in an airtight container in the refrigerator for up to 1 week. Enjoy heated up, cold or room temp!
Tools You’ll Need to Make This Easy Quiche Recipe:
Food processor. Ours sees so much action we stopped even trying to put it away. Now it just lives in its happy little place on our counter, and honestly we don’t mind one bit.
Quiche pan or pie pan. You don’t have a quiche pan?! Not to worry—a regular 9-inch pie pan will do.
