This melt in your mouth Easy Crustless Zucchini and Cheese Quiche takes only ten minutes to prep. This crust-less quiche has a flavorful and creamy filling and tastes so good even cold! The perfect recipe to use up summer zucchini!
We have been prepping for Hurricane Dorian for days. It’s been a lot of back and forth with its track and at most points, it was coming at us as a direct hit. When it seemed things were looking brighter for us, I was figuring out what to do with leftover vegetables. In case we would lose power (and we still could today when the winds get worse later on) we were baking and cooking. We made a zucchini bread and a banana bread. There are blueberry muffins and I roasted up all my tomatoes with my leftover thyme (they are delicious!). The last thing we made was this crustless zucchini and cheese quiche.
When I was growing up the Bisquick quiche recipe was quite popular. It was actually one of the first recipes I learned to make when I was experimenting on my own in the kitchen. It became a famous recipe as it is so easy to make and so tasty!
When I became more experienced in the kitchen I had to figure out how to make this quiche without using something boxed. And it truly is so easy to do with ingredients you already have! This quiche is the perfect recipe for busy parents that need something fast and flavorful on those crazy school nights!
All credits to mom who sent me her handwritten recipe to work with and she actually made this one for us to enjoy. I find such joy being able to bake alongside my mom and learn her tips and tricks.
Do I need to make a crust for the quiche?
It is not necessary to make a separate crust for this quiche. This is a remake of the very popular Bisquick quiche. All the ingredients are mixed together. It is light and fluffy and perfect as it is.
Some Tips for the best Crustless Cheese and Zucchini Quiche
- This crustless quiche could be made to your liking. Originally it called for bacon or ham (so good!)and Swiss cheese. I have very fond memories of the bacon version!!
- This version is vegetarian and we also used dairy-free cheese for our dairy free kid. Use your favorite cheeses to make it your own.
- Take the time to let the quiche cool down a bit before diving in. Taking that slice too soon will just make a mess.
- Perfect for a party! Simply use a 9×13 pan and double the recipe. Since it is just delicious, I suggest making the larger portion so you’ll have more recipes. Or make two pie plates.
- Eggs will rise. The quiche will settle after you take it out. Take care not to overfill when you pour into your pie plate.
- We usually make with Parmigiano Reggiano and mozzarella cheeses. This particular one was made with dairy-free cheeses, and was delicious. SO whatever cheeses you want to use will be great!

Easy Crustless Zucchini and Cheese Quiche
- 4 cups zucchini grated and drained
- 1 small onion chopped
- 1 cup all-purpose flour
- 1 ½ tsp baking powder
- ¼ tsp salt
- 4 large eggs
- ½ cup vegetable oil
- ¼ cup Parmegiano Reggiano grated
- ¼ cup mozzarella cheese grated
- ½ teaspoon marjoram or dried thyme
- 1 Tbsp parsley chopped, just leaves
- ¼ tsp salt
- ⅛ tsp pepper
- Preheat oven to 350. Spray a pie plate with baking spray; set aside.
- Grate the zucchini. Place in a colander and squeeze out all of the water. Remove the zucchini. Stir in the chopped onion; set aside.
- In a small bowl, with two forks or a pastry blender, mix the flour, baking powder, salt and vegetable oil well until small pea sized pebbles form; set aside.
- In a large bowl, with a fork, mix together the eggs. Add in the herbs, salt and pepper. Gently stir in the flour mixture with a spoon. Add in the grated zucchini and onion. Stir in the cheeses. Gently combine to make sure it is all evenly distributed.
- Carefully pour into your prepped pie plate. Bake for 45-50 minutes. Check around 30 minutes and if it seems to be browning too quickly, cover with foil paper. Every oven is different and we bake ours the whole time uncovered.
- The quiche will be done when a fork comes out of the middle mostly clean. Keep in mind that the quiche will rise, but then deflate a little.
