Ingredients needed

This delicious sweet potato quiche recipe is made with simple good-for-you ingredients that will keep you satisfied right up until lunch. Here’s what you’ll need:

• Bacon. Always a favorite! You can swap the bacon for turkey bacon, Canadian bacon, diced ham or even sliced chicken sausage, if you prefer.
• Sweet potato. I’ve made this with both sweet potato and butternut squash. Wonderful either way!
• Spinach. Sauté one bag of baby spinach leaves before adding it to the quiche. A great way to sneak in extra nutrients!
• Eggs. You’ll need 8 large eggs for this recipe. If you can get your hands on farm fresh eggs, I highly recommend them.
• Milk. You can use any milk that you have on hand: skim, 2%, whole, almond, or cashew milk.
• Salt & pepper. To really bring out all of the delicious flavors.
• Cheese. I love using shredded Mexican style four cheese blend to top this quiche. However, feel free to use any favorite cheese variety.

Even though this sweet potato quiche recipe is very simple to put together, you will need to have cooked sweet potato and cooked bacon. Below, are several options and tips for cooking both:

Ways to cook sweet potato

You will want the cubed sweet potato to be fork-tender before adding it to the quiche. There are several ways to accomplish this – feel free to pick your preferred method.

• Roasting. You can roast the sweet potato up to about one day in advance of actually making the quiche. To roast, preheat oven to 425ºF and place diced sweet potato in an even layer on a large baking sheet lined with parchment paper. Place in the oven and cook for about 20 minutes and just until the sweet potato is tender, but not too mushy.
• Sautéing. Heat a large skillet over medium heat and spray with nonstick cooking spray or add a drizzle of olive oil. Cook diced sweet potato, stirring frequently until fork-tender, about 10-15 minutes. I often cover the skillet for a few minutes to speed up the cooking process. The great thing about using this method, is that you can transfer the cooked sweet potato to the pie dish and the skillet is already heated to cook the spinach.
• Microwaving. Place 1-2 whole sweet potatoes in the microwave for 8-10 minutes and until they are soft enough to easily dice, but not overly mushy. You can also microwave diced sweet potato for a shorter amount of time, if preferred.

Ways to cook bacon

For this particular recipe and since you’ll be needing 8 slices of cooked bacon, which is quite a few slices, I like the hands-off method of baking the bacon. Here’s the options:

• Baking. Preheat oven to 400ºF. Line a very large baking pan with parchment paper, then place the bacon side-by-side on the pan. Cook the bacon for 20-25 minutes or until it’s reached your desired level of crispiness. I like mine crispy! Remove the tray from the pan and transfer the bacon with tongs to a paper towel-lined plate. Once cooled, crumble up or dice for the quiche.
• Sautéing. Add bacon to a large skillet and place over medium heat, cook bacon on both sides until crispy and golden brown. You may need to cook bacon in batches, if you only have one skillet. Remove cooked bacon to a paper towel-lined plate and cool slightly. Then crumble or chop into bite-sized pieces for the quiche.

How to make this recipe

Classic quiche recipes are made with a mixture of milk and eggs that gets poured into a crust, then baked. However, making a crustless quiche works great and personally, is how I prefer my quiches to be served. Here’s the simple process:

1. Start this quiche by cooking the bacon, sweet potato and spinach. Once those ingredients are cooked, all you need to do is layer them in a pie dish and bake!
2. Layer ingredients in pie plate. Preheat your oven to 350ºF and spray a 9-inch pie dish with cooking spray. Layer the bottom with sweet potato, then spinach, and then bacon.
3. Make the egg mixture. In a bowl with a whisk, mix the milk, eggs, salt & pepper. Then pour the mixture into the dish, over the sweet potato, spinach, and bacon layers. Sprinkle the top with cheese.
4. Bake. Place in the oven and bake uncovered for 45 minutes. Allow the quiche to cool for 10 minutes before slicing and serving. Enjoy!

Expert tips

• Make ahead. All of the components for this quiche can be made a day before using – the custard mixture, sweet potato, bacon and spinach. Store any or all of them in the refrigerator and for the custard, stir again before pouring over the sweet potato.
• Add mix-ins. Feel free to experiment with adding in other ingredients before baking. Sautéed onion, bell pepper or mushrooms would all be delicious. This quiche is very versatile – you can use kale instead of spinach or leave the greens out entirely. You can also replace the sweet potato with butternut squash.
• Time saver. To save on prep time, buy pre-cooked bacon, pre-shredded cheese and pre-cubed sweet potato.
• Garnish. Feel free to garnish the finished dish with fresh chopped herbs. Chives, basil, parsley, green onions or dill all work great.

Frequently asked questions

Ways to customize this recipe  

We love this as written, but feel free to experiment and switch up some of the ingredients, depending on what you have on hand. Here are some options:

• Protein. We always use bacon, but feel free to use pork or turkey sausage. You could even try diced cooked ham.
• Vegetables. You can add your favorite cooked vegetables to the quiche such as sautéed onions, peppers, or mushrooms.
• Cheese. The Mexican cheese blend is so good, but other great choices are mozzarella, Monterey Jack, or Swiss cheese.

How to store, freeze & reheat

Good news! Quiche is a great make ahead dish. You can store this either in the refrigerator for about 5 days, or in the freezer for up to 3 months.

• Storing in the refrigerator. To refrigerate the entire quiche, allow it to cool completely, cover it, and store it in your refrigerator for up to 5 days. To reheat it, cover it with foil and place it in the oven at 350ºF for 15-20 minutes. Alternatively, you can reheat individual servings in the toaster oven for about 10 minutes or in the microwave for about 1 minute until heated through.
• Storing in the freezer. To freeze individual slices, cool completely and then wrap them in plastic wrap and foil. Place them into airtight containers or ziptop bags in the freezer. To reheat, unwrap the slice and place on a microwave safe dish at 30-second intervals for about 1 minute until heated through.
• If you want to freeze the entire crustless quiche, make sure it cools completely, then wrap it in plastic wrap and cover it tightly with foil. Before reheating, allow the quiche to thaw out a bit, then place it in the oven for 20-30 minutes at 350ºF until it’s heated through.

I know you’re going to LOVE this easy quiche recipe because it’s SO satisfying and flavorful. And it’s awesome that it can be adapted to any favorite add-ins! It’s quickly become one of my favorites for lazy weekend brunches, or prepping in advance for easy lunches.
