Crustless Zucchini and Pesto Mini-Quiches {PAM Cooking Spray Review}

When PAM cooking spray asked me if I wanted to review their new and improved product I was very excited. First and foremost, because it was new and improved. I am no stranger to cooking sprays but using them on certain pans usually has mixed results.
In the case of muffin tins, I don’t like the sticky residue that is often left behind and hard to remove. I don’t like that even though I have sprayed each of the cups, things stick in them. And so I wanted to find a recipe to recreate that would be a real challenge. So I turned to YOU, my readers. And you, my friends, do NOT disappoint.
To make this the most difficult challenge possible I tried three of the toughest things mentioned against the NEW PAM cooking spray: eggs, cheese, and messy toddlers! Here is a step-by-step video of our process and the results:

These crustless quiches do not disappoint either. As noted in the video we made them as part of this week’s cooking school where we were doing letter “E” and letter “F”. This one was obviously “E” for eggs. The sneaky goodness of spinach mixed with some pesto gives these the added taste they need to be delicious. Oh yea, that cheese crust helps too! They are perfect for flash freezing and warming quickly each morning in the microwave too. Nothing like a hot protein breakfast that you can eat on the go.

Ingredients:
- 0.25 cups cornstarch
- 1.25 cups whole milk
- 4 large eggs
- 1 cup heavy cream
- .75 teaspoons kosher salt
- 1 Tablespoon Olive Oil
- 2 teaspoons garlic, minced
- 4 green onions, sliced
- 1 medium zucchini, grated
- 2 Tablespoons Pesto
- 4 ounces Mozzarella cheese, shredded
- PAM Cooking Spray (coupon for $.50 off – download before 11/15/11 and use before 11/30/11)
Directions:

Fill them 3/4 full and don't be afraid to spill if you used PAM cooking spray!
Put the cornstarch in a medium bowl. Whisking steadily, slowly pour in .5 cups of the milk, mixing until combined. Whisk in the eggs, mixing again until combined, then gradually whisk in the rest of the milk, the cream, and salt.
In a nonstick pan, heat oil over medium heat. Add garlic and green onions and stir for about 2 minutes. Add grated zucchini, and stir until just softened, another 3-4 minutes. Remove from heat.
Spray muffin tins with PAM cooking spray. Put a pinch of Mozzarella cheese into each muffin cup, a teaspoon of the zucchini mixture, and a teaspoon of pesto. Pour batter into each muffin cup, filling 3/4 full.
Bake at 400 degrees until the quiches puff and start to turn golden, 18-20 minutes. Let cool for 10 minutes and remove from muffin tins. Serve.
Freezing Directions:
Follow the indicated directions above including baking them. Let cool, then flash freeze. When partially frozen add them to a gallon freezer bag, seal and freeze. Reheat on a cookie sheet in a 400 degree oven for about 5-10 minutes or microwave for 30-60 seconds.
Servings: 16 muffins

In the cooking directions you say to add garlic and onions, but I don’t see garlic listed in the ingredients.???
:) I probably just mentally added it as I add garlic to everything. :) I’ll make the change. Thanks.
Thanks for the recipe! I freeze a bag of crustless quiche every week for my husband who has to get up very early everyday for work. This way I don’t have to get up with him to cook his breakfast. :) I have never tried making quiche with pesto. Sounds delicious!
This looks really yummy! I’m eager to try it. Have you tried adding nutmeg to the recipe? I understand that anytime you have spinach and cream in something, adding just a bit of nutmeg really improves the flavor. I’ve added it to recipes that have these ingredients in the past and loved it.
The original recipe had nutmeg but I tweaked it out. You most certainly are welcome to add it back in though. I just felt like the addition of pesto might not react well with the nutmeg.
Oven temp for initial bake?
Sorry, 400, just like the reheat.
Thank you so much! I made 3 batches of these to freeze tonight and they are delicious!
You are most welcome! :)
I would like to make the crustless zucchini and pesto mini quiches using the new pam cooking spray. I still have zucchini left from my garden!
