Goat Cheese Quiche with Spinach and Caramelized Onion

This gorgeous goat cheese quiche with spinach and balsamic caramelized onion is not only the prettiest quiche your guests will ever see, it’s also made with a low-carb, nutritious (and delicious) zucchini crust!

With a fourth of the calories and carbs as a traditional, flour-based crust, and twice as much tastiness (in my opinion), your carb-counting guests can enjoy this beautiful quiche, guilt-free!

A Few Tips!

1. You can use either fresh or frozen spinach.

I’ve made this quiche with both fresh and frozen spinach and I have to say, I didn’t notice a difference between them. Just make sure that if you’re using frozen spinach, it’s thoroughly thawed, drained and squeezed so there isn’t any water when you add it to your quiche mixture.

2. Make that tasty zucchini crust!

You can certainly make this quiche with a traditional, flour-based crust, but that zucchini crust is so much better! A slice of flour-based pie crust has 121 calories, 14 grams of carbohydrates, 8 grams of fat and virtually no actual nutritional value whatsoever. My zucchini crust has only 71 calories, 7 carbohydrates and 2 grams of fat. It also includes vitamins A, C, Calcium and Iron. It’s also SO much tastier, so it’s a no brainer.

A Few Common Questions:

1. How do you reheat this quiche?

2. Can I make this quiche without any crust at all?

Certainly. Just make sure to very liberally grease your pyrex pie dish or tin.

3. How long will it last in the fridge?

This quiche will last nicely for 5 days if covered by cellophane.

4. What will I require for this recipe?

  • cheese grater
  • large mixing bowl

How to Make Goat Cheese Quiche with Spinach and Caramelized Onion – Step by Step

NOTE:  You can bake your onion roses and quiche at the same time if you have a large oven. You can place the onion roses on the top rack and the quiche on the bottom, but only as long as the top pan doesn’t block the quiche from the heat that comes from the top of your oven.

A step by step process showing how to make zucchini quiche crust.

1. Pre-heat oven to 375 F. and shred 2 zucchini. 

2. Place it in a mixing bowl and sprinkle with 2 tsp. of salt. Stir and allow it to sit for 20 minutes to allow the moisture to release.

3. Squeeze the moisture out of the shredded zucchini with cheese cloth, making sure to eliminate as much water as possible.

4. Place it back in the mixing bowl with ¼ cup of flour, 2 tbsp. grated parmesan, 1 egg, ½ tsp. garlic powder and a sprinkle of pepper and mix.

5. Grease a pie pyrex or tin with butter and evenly distribute the zucchini “dough” on the bottom and up the sides. Bake for 30-40 minutes and prepare your quiche ingredients while it bakes. You’ll know it’s done when the edges turn brown and it’s no longer sticky.

6. If you’re using frozen spinach, thaw, drain and squeeze the water out of half of a traditional package (which should be 5 ounces). If you’re using fresh spinach, chop 5 ounces of the leaves into small pieces and set aside.

7. Grate 2 tbsp. of parmesan cheese and set it aside.

8. Slice your medium red onion into rings. You can also simply chop the onion, but I think the rings look prettier.

A step by step process showing how to make quiche.

9. Add 2 tbsp. of olive oil to your frying pan and sauté until they’re golden brown, about 7-10 minutes. Once brown, add 1 tsp. of balsamic vinegar to the pan and quickly stir the onions. Allow them to sauté for another 30 seconds.

10. To your large mixing bowl, add 6 eggs, caramelized red onion, spinach, 2 tbsp. grated parmesan, ½ cup heavy cream, ½ cup whole milk, 2 ounces of herbed goat cheese (half a traditional small package), 1 tsp. of salt, a small sprinkle of pepper and a smaller sprinkle of nutmeg. Stir until all ingredients are thoroughly mixed.

NOTE: Your zucchini crust should either be done by now, or just about finished, and it will be ready for your quiche ingredients after cooling for just 5 minutes.

11. Keep the temperature at 375 F. once you remove the crust. Use a slatted spoon to add the onions and spinach to the crust first, allowing the egg mixture to run through a bit before you do. You want your ingredients to be evenly distributed before you pour the rest of the mixture in. Once you’ve poured the rest of the egg mixture into the crust, add a few dollops of left-over goat cheese to the top of the mixture. Bake for 40-45 minutes on the bottom rack.

12. While your quiche begins to bake, Peel 6 or 7 pearl onions and slice them in the center. Place them on a foil-lined pan and drizzle with olive oil and a little bit of balsamic vinegar. If you have a large enough oven to place the onions on the top rack without blocking the bottom rack from the oven heat, you can bake them on the top rack at the same as the quiche for 15-20 minutes. However, if your oven is too small, wait till your quiche is done, then bake the onions while it cools and sets. If you want to see a great tip on how to peel pearl onions in a flash, take a look at this recipe.

Once the quiche and onions are finished, place the onions on the quiche in a pretty, floral design and serve.

    This quiche was delicious! I didn’t have time to make the zucchini crust, but I made an “onion rose wreath” like yours. It really stood out at my church pot-luck lunch. Two thumbs up!
