Mini Caramelized Onion, Spinach and Potato Quiches

I forgot to spray my pan, so my quiches stuck, they’ll come out prettier if you remember that step- opps!

 

Quiches are a tasty, relatively quick meal that are great with a huge range of ingredients. This was my first time putting caramelized onions in a quiche and it tasted great, it was definitely worth the extra time that it took to cook the onions. I also threw some pepper jack cheese into the mix which that added just the right amount of kick to help these quiches stand out. The little mini quiches are great if you’re feeding a group and they also freeze and re-heat well if you aren’t!

Mini Caramelized Onion, Spinach and Potato Quiches 

Ingredients

  • 1 sweet onion, chopped
  • 1 tbl. olive oil
  • 1 cup spinach, packed
  • 1-2 small potatoes
  • 7 eggs
  • 1/4 cup milk
  • 1 1/2 oz. pepper jack cheese, grated or cut into small pieces
  • Salt and pepper to taste
Directions
  1. Preheat the oven to 350 degrees and lightly spray a muffin tin with non-stick cooking spray.
  2. Pour the olive oil into a sauce pan over medium heat. When it’s hot, add the chopped onion and cook for about 15-20 minutes until the onions caramelize. Add a bit more olive oil as the onions cook if necessary.
  3. While the onions are caramelizing, cook the potato(es) in the microwave until they are tender. Chop the potatoes into small, bite sized pieces.
  4. When the onions are nearly done, add the spinach. Cook and stir for about a minute until the spinach wilts.
  5. Mix the eggs and milk, whisk until combined. Stir in the spinach, onion, and cheese. Add salt and pepper.
  6. Pour the egg mixture equally into the muffin tins and then drop in the potato pieces.
  7. Cook for approximately 20 minutes. The quiches are done when they look set and don’t jiggle when the pan is moved. Let the quiches cool for a few minutes before serving. Enjoy!

  1. Oh my goodness YUM! I’ve been looking for some new quiche ideas and WHUDYAKNOW? I just so happen to have all this stuff in my fridge. =D (PS ~ I should play the lotto today – I just stumbled upon your blog in a comment on Bakeat350 and found this post – lucky me! Thanks ~ Kristi

  2. Annie, I’ve been looking for a great quiche recipe with spinach and this sound wonderful.

    I found your blog through the recipe exchange and I must say it cracked me up when I saw that the lab is a dog.

  3. Hi Annie – I took these mini quiches to a Halloween party last weekend and they were gone in a minute. I should have doubled the recipe. Tender and delicious – the carmelized onions were key to the flavor. Thanks, Bets

  4. I bet this would be a great way to cute the calories and fat from most quiches too! With no crust and some non-fat milk it would be a quick go to for low cal meals!!

  5. I am falling in love with food blogs. I don’t do dairy and just found the most awesome vegan cheese yesterday at a Green Festival. I am going to give this a try this week. Only which onion is the “sweet” onion?

    • At my grocery store they are just called ‘sweet onions’ sometimes it specifies that they are from Hermiston or Walla Walla (either is fine). If you can’t find sweet onions though, don’t worry about it, a regular yellow onion will still be great and it’ll work just as well!

  6. These look so good. They will probably be perfect as an appetizer for my Thanksgiving dinner. How well will they freeze, and what instructions can you give for re-heating them? Thank you!!

    • I’ve had great luck freezing them, I love to pull them out for a quick meal when I’m busy with school and work. I like to wrap each one individually in plastic wrap before putting it in a freeze-safe ziplock bag, and then I also try and suck all the air out of the bag. To reheat them, I just put them straight from the freezer into the microwave and heat it for a few minutes until they’re hot all the way through!

  7. These look delicious. I’ll definitely try them. My husband is vegetarian, and when he goes away on business trips I eat meat every day. However, when he’s home we try to be inventive: my challenge is that we make vegetarian meals that are so complete and satisfying that carnivores need not even think of meat as a suitable accompaniment. He makes a mean eggplant roast, which hits the mark, and a cauliflower and smoked mozzarella frittata, which also meets the challenge. I suspect somehow that your quiches are up there too.

    • Most of my family members are meat-eaters as well, it’s tricky coming up with recipes that can satisfy everyone. It would be easy to add a bit of chopped up ham or bacon to half of the recipe too if you were looking for some meat to add in to your portion.

  8. Yummy! I know what I´ll cook next time friends come and visit!
    Here´s another recipe – savoury truffles.

    Mix some soften goats or soft cheese on a bowl and season with salt and pepper, make some balls and dip them on some honey and water before covering them li with chives, pink peppercorns or sesame seeds.

    • That’s interesting, I haven’t noticed much of a difference between various types of onions, but some types seem to caramelize more quickly. I’ve never added sugar to mine, but I have seen a few recipes where people add a small pinch of sugar to the onions at the beginning of the cooking process. Maybe that would help? Sorry I don’t have a better answer for you!

  9. Annie: The best thing about this recipe is that it is gluten-free! It is difficult to make any quiches without flour. I have Celiac Disease so I’m constantly on the lookout for recipes like this. I will definitely try these over T-Day holidays. If they work, then onto Christmas! Congrats on being FP’D!

  10. Wow, the photo is awesome. I am a HUGE quiche lover and have a few posted on my blog. I think caramelized onions are the new black. They seem to be popping up in recipes everywhere these days. Maybe its a seasonal thing.

  11. I am not a quiche guy, but this sound delicious and I will have to try. I love your sous chef, I have 3, my 11 year old daughter and my two obstacles Lucy and Sam my Golden Retrievers

  12. first of all, your cupcake/dog picture is beyond cute. and second, i’m having a hard time holding back the drool at the thought of your quiche. yummmm.

  13. Great. I’d make it with soy milk and veggie cheese because I am a health nut though. Please take a look at my book on higher consciousness. It is at TheGreaterReality.com
