Bacon & Spinach Mini Quiches

I have green-averse kids, so when I find a way to make a green food appetizing, I share it with you as I did with my green smoothie recipe that doesn't taste green or my broccoli nuggets. Now, crustless mini quiches!

These quiches are made in a single bowl and kids can help with the process. Something else I love is that they can be customized with different veggies, meats, and leftovers. I've even made a zesty version and they are delish!

By the way, if you are looking for a larger version, try this quiche recipe made with puff pastry! The flaky crust makes this one a crowd-pleaser for lunch or dinner!

Ingredients

If you need this recipe to be vegetarian, omit the bacon. Need to make the crustless mini quiches dairy-free? Skip the cheese. Yes, it’s super easy to customize! Check what I use and the possible swaps:

  • Eggs: essential to bind the ingredients.
  • Milk: use any dairy or non-dairy milk.
  • Spinach: you can use any other veggie leftovers or your favorite ones.
  • Cheddar: or any shredded cheese you have.
  • Bacon: makes everything tastier! If you have meat leftovers, you can also use them.
  • Pepper: just a dash!

How to Make Crustless Mini Quiches

Easy, easy, easy! You can make these crustless mini quiches effortlessly, with very little clean-up in no time! Epic, I know! Here are the steps:

  1. Prep
    Preheat the oven, grease a mini muffin pan or a regular-size one, and chop the spinach.
  2. Combine
    First, whisk eggs and milk and then add the rest of the ingredients.
  3. Bake
    These crustless mini quiches take 15 to 18 minutes to be ready. If you use a regular-size muffin pan, you’ll have to bake them longer.
  4. Cool down
    Allow them to cool down before removing them from the pan carefully.

I shot the video for this recipe with my 3-year-old and he really surprised me showing me he was able to follow the (easy) steps for this recipe. To see him in action, click on the video below:

Preventing Soggy Mini Quiches

The main reason for soggy mini quiches is not cooking them long enough. Cook them at 350F for 15 to 18 minutes until the quiches are golden brown and don’t jiggle.

If you decide to include veggies like zucchini, make sure to cook them first before adding them to the mix; this way, you keep them from releasing too much water in the oven and making your quiches mushy.

Recipe Variations

These mini quiches are my favorite way to repurpose those leftovers that are not enough for another meal but still have nutrition and flavor to offer. Here are some tasty ingredients you can add to your crustless mini quiches:

  • Carrot and zucchini
  • Pizza toppings
  • Taco meat leftovers
  • Mushrooms
  • Ham and cheese
  • Breakfast sausage
  • Cottage cheese
  • Onions and bell pepper
  • Broccoli
  • Peas
  • Asparagus

Storing Leftovers

Once the mini quiches are cooled down to room temperature, place them in an airtight container or zip bag and store them in the fridge for 3 days. These are also perfect to freeze! So go ahead and cook them in bulk to freeze and use when you need them!

Packing Leftovers for Office Lunches

Leftovers make a great lunch! You can heat them up for 1 minute in the microwave and send them inside a thermos to enjoy them warm or pack them in any lunch container to eat at room temperature.

      Absolutely. I send these at room temperature inside the lunchbox all the time.

        These are so good! Super easy to throw together and great to bring to a gathering for a gluten free option. Sometimes I use heavy cream or half and half in place of the milk depending what I have on hand. Also I add onion powder, garlic powder and a salt herb blend. Thank you for such a great recipe!

          Hi,
          a very good and tasty recipe. I just find hard to take quiches out of the tray once it is baked. They stick. What is the best solution to take them out easily?

            You need to spray your non-stick muffin pan very well or get a different brand. This is the one I use and recommend because they practically slide off.

    Do I need to change the cooking time or amount of ingredients if I don’t use a mini muffin pan and just use a regular muffin pan?

      They should take 20-22 minutes in a regular muffin pan. You’ll notice that the eggs are puffy and cooked through the middle.
