Zucchini and Sweet Corn Quiche

It is still zucchini season, and it’s nothing to shy away from, that is for sure! The combination of two healthy foods, eggs and zucchini, just make sense! Quiche is traditionally made with a crust, but without a crust, like this Zucchini and Sweet Corn Quiche, is considered a crustless quiche. Clever, huh?! In fact, crustless quiche is a lot healthier than a traditional quiche with a pastry crust so this recipe is a winner in more ways than one!

Ingredients for Zucchini and Corn Quiche

Zucchini and Sweet Corn Quiche Recipe

Sometimes when I think of a hot breakfast, I think of how much work it will be and if I have the time to make it. Zucchini and Sweet Corn Quiche does not require a huge amount of prep work, and it lasts for up to three days if you have any leftovers. Breakfast is such an important part of the day, and I can really notice a difference when I start my day with a fulfilling meal.

How to Mince Fresh Herbs

Zucchini and Sweet Corn Quiche calls for basil, oregano, and garlic. Using fresh herbs makes a big difference in a recipe when it comes to taste and flavor. It is not as intimidating as you might think, mincing fresh herbs. I know that garlic is arguably a vegetable, but I am keeping it in this herbal category when talking about mincing. The extra few seconds, which is really all the time it takes to mince herbs, will be worth it! Make sure you wash and dry the fresh herbs before chopping and mincing.

Minced Basil

With fresh basil, remove the leaves from the stems and throw the stems away. Roll the leaves and chop as finely as you can. Then, to get an even finer cut, bounce the knife over the leaves again, letting the knife do the work.

Minced Oregano

Carefully remove the leaves by sliding your fingers along the stem. For any leaves that did not come off, simply remove them individually. Once you have a pile of leaves, you will want to chop them up since that brings out more of the flavor of the dish. The keyword is pile. The denser the pile of oregano leaves, the easier it will be to chop them up into tiny pieces.

Minced Garlic

You will never buy minced garlic again after you take the time to mince it yourself. The flavor is so much more pronounced when you use fresh garlic. Just wait until you get that garlicky aroma after adding it to the butter! First, peel the garlic bulbs, and then smash each bulb with the side of your chef’s knife. Put together the smashed pieces and chop away! It’s as simple as that!

How to Slice a Zucchini

It’s time to invest in a mandoline slicer if you do not have one already. This will give you perfectly sliced vegetables, as thick or as thin as you would like every time! It worked great to use for the zucchini in my Southwest Zucchini Roll Ups. This should not be confused with the musical instrument, the mandolin. If you accidentally order one of those, I can’t wait to hear you play a song on it!

How to Make Zucchini and Sweet Corn Quiche

Now that you have your herbs minced, zucchini sliced and ingredients ready to go, it’s time to put together the Zucchini and Sweet Corn Quiche. Preheat the oven to 375°F while you mix and cook most of the ingredients on the stovetop. Using a skillet that you can transfer to the oven, melt the butter over medium-high heat. After the butter has melted, add the onions, garlic, zucchini, and corn. Can you smell the aroma of your freshly minced garlic?!? Cook this combination for 5-10 minutes, or until the zucchini is cooked through.

Remove the skillet from the heat and add in basil, oregano, salt, 3 cups of the cheese, tomatoes, and eggs. Stir it all together and add top it off with the remaining cup of cheese. Make a foil tent to cover your quiche, and bake it in the oven for 20 minutes. Remove the foil tent after 20 minutes and let the quiche cook for 5 more minutes before you take it out of the oven. Let it sit for about 15 minutes before serving. Remember, Zucchini and Sweet Corn Quiche is great as a leftover or dinner! Keep it refrigerated for up to 3 days.

  1. This took at least 15 minutes longer in the oven than the recipe calls for. Also…how large of a skillet did you use? Because 2 large zucchini is a LOT. I used a large cast iron skillet, it was difficult to cook down an probably why it takes so long in the oven. I don’t know if I’ll make this again.

  2. Do you happen to know the carb count for this? Since discovering this recipe I have been making it every week (it’s been months now)!! ❤️ Love this! When reheated I top with thin cut ham along with additional shredded mozzerela cheese, delicious!
