Prosciutto Quiche with Roasted Brussels Sprouts

A Delicious Leftover Pie

This delicious prosciutto quiche all started as nothing more than a quick grab of leftovers in my fridge. It was off-the-hook amazing and now I’ll roast up some Brussels sprouts just to make the quiche. What’s great about quiche though, is that you can easily swap out ingredients based on whatever you have in your fridge.

Don’t care for Brussels sprouts? Roasted broccoli, asparagus, cauliflower will all work! Short on green onions? Go for shallots, chives, or even regular onion. Cheddar too sharp for you? Gruyere, Swiss or any cheese of a similar consistency will work.

Prosciutto Quiche Making Methodology

It’s all in the pan!

Prosciutto Quiche with Roasted Brussels Sprouts - 1Prosciutto Quiche with Roasted Brussels Sprouts - 3Yes, you can use a standard pie pan for making my prosciutto quiche, but you’ll have to adjust cooking temperature and time. For the best results use a quiche pan – which is wider and shallower. Better yet, if you have one with removable sides, it’ll make for a more dramatic and beautiful serving. Get it here.

Roast up those veggies!

Brussels sprouts, ready to roast!

If you start with raw vegetables, they will not soften appropriately and you’ll wind up with harder chunks of vegetable. While steamed vegetables will also work, roasting the Brussels sprouts will give you a more developed flavor and add some sweetness. Roasting vegetables is easy! Quarter the Brussels sprouts, toss the with avocado oil (or olive oil), salt and pepper and spread them out on a lined sheet pan or cake pan. Bake at 400 F for about 30 minutes and you’re ready to go. Prosciutto is salty by nature, so if you’re roasting the vegetables specifically for the quiche, you’ll want to go easy on salting them.

Saute the prosciutto & green onions.

When you take the extra few minutes to saute the prosciutto and green onions together, you’ll get more depth of flavor. I like to get the prosciutto just a little crispy. There’s no need to add any oil, the fat will render from the prosciutto as you’re cooking it.

Arrange the prosciutto, Brussels and cheese in the pan first.

Do not mix all the ingredients into the custard mix. Instead, spread out the prosciutto, Brussels sprouts and cheese in the pan. This is how you make sure that your meat and veggies are evenly distributed throughout the quiche. Now you don’t have to worry about getting the right mix of meat, vegetable and cheese in every slice. Once arranged, pour the whisked eggs and milk into the pan.
