Dairy-Free Spinach Quiche


This delicious dairy-free spinach quiche is flavorful and creamy without any cheese, milk or meat. The best part? It can be served for breakfast, brunch or dinner.

Our family and friends were so gracious to set up a meal train for us when Olivia arrived. One of my favorite meals that we received was a spinach quiche and it quickly made me realize that quiche is the ultimate food to bring to new parents for a variety of reasons. 1) You can eat it with one hand. 2) It works for breakfast, lunch or dinner and 3) It can be eaten cold, straight from the fridge or reheated!

Trust me, when you’re sleep deprived, hungry and holding a screaming baby all of these things are helpful.

I already have a crustless quiche recipe, but decided to make this spinach quiche with a crust to keep it traditional. The crust also helps to make the quiche a bit more filling.

Most quiches are loaded with dairy to add additional flavor and creaminess, but you don’t need it! This quiche is packed with flavor and doesn’t have cheese OR milk. Many new mamas have to go dairy-free if their baby has a milk protein intolerance or allergy so I wanted to create a quiche that would work for these moms! Instead of cow’s milk, we’re using oat milk to make this quiche creamy without the dairy.

Let’s jump into the recipe!

Here’s What You Need:

  • pie crust – you can make your own, but there’s no need. I used one from Wholesome Organic and it was delicious
  • onion, garlic, bell pepper
  • spinach – you can use frozen or fresh
  • eggs and egg whites
  • oat milk
  • seasonings and spices – dried Italian seasoning, sea salt and pepper
  • nutritional yeast – adds extra nutrients and a “cheesy” flavor without the cheese

Tips for Draining Frozen Spinach

We’re using frozen spinach for this quiche recipe and there are a couple extra steps to prepare the spinach. If you remember to take it out the night before, place the frozen chopped spinach in the refrigerator to thaw. If you forget, don’t stress! Place the frozen spinach in a microwave-safe bowl and microwave for 1-2 minutes or until the spinach is thawed.

After your spinach is thawed, you want to get the spinach as dry as possible. Wrap the spinach in paper towels or clean kitchen towels and squeeze out all of the excess moisture. I like letting the spinach sit wrapped in paper towels while I prep the rest of the ingredients to make sure every last drop is absorbed by the paper towels.

Storing and Reheating Quiche

If you want to use this as a meal prep recipe or a meal train recipe, fully cook the quiche and then let it cool completely in the refrigerator. It will keep for up to five days in the refrigerator when kept in an airtight container. Like I said earlier, you can eat it cold, right out of the fridge or reheat it. My personal preference is to reheat it in the toaster oven.

Prep Time 15 minutes
Cook Time 52 minutes
Total Time 1 hour 7 minutes
Servings 8


  • 1 9-inch pie crust (gluten-free, if needed)
  • ½ teaspoon olive or avocado oil
  • 1 onion, chopped
  • 2 cloves of garlic, minced
  • 1 cup chopped red, yellow or orange bell pepper
  • 2 teaspoons dried Italian seasoning
  • 8-10 oz frozen chopped spinach, thawed and drained*
  • 1 teaspoon sea salt, to taste
  • ¼ teaspoon freshly ground black pepper, to taste
  • 3 large eggs
  • cup egg whites, or 3 additional eggs
  • cup unsweetened oat milk, or other non-dairy milk
  • 2 Tablespoons nutritional yeast
  • fresh chopped thyme, for garnish


  • Preheat oven to 400°F. 
  • All oil to a medium skillet over medium-high. Add onion, garlic, bell pepper and cook until onion is translucent, about 6-7 minutes. If you’re using fresh spinach, after about 5 minutes add in your chopped spinach until cooked down. Sprinkle salt and pepper on veggies while they cook. Set aside to cool.
  • While the veggies cook, make sure the spinach is as dry as possible by squeezing out all of the water. I like wrapping the spinach in a couple paper towels while squeezing to help absorb some of the liquid. 
  • In a small bowl, whisk together eggs, egg whites, oat milk, Italian seasoning and nutritional yeast. Scatter veggie mixture and chopped spinach on the bottom of prepared crust. 
  • Pour egg mixture over top and push under any ingredients not covered by the egg mixture to prevent burning. Bake uncovered until set and golden brown around edges, about 45 minutes. Let quiche rest at room temperature for 10 minutes, then cut into slices, top with fresh thyme and serve.
  • Store leftovers in the fridge for up to 5 days. Reheat in the oven or toaster oven.


  • If you don’t have frozen spinach on hand, you can use fresh spinach. I used 3 big handfuls (about 3 ounces) out of a 5 ounce bag of pre-washed, fresh spinach, roughly chopped.

      Looking forward to making this, but wondering why the photo looks like it has yummy cheddar cheese on it? Is that from the eggs? Or does nutritional yeast give it that effect?

        Hi Partice – There are some orange bell peppers in the photos, along with the color of the eggs. The nutritional yeast only adds the flavor. There is no cheese. Hope you enjoy this recipe!

      Dumb question- I assume nutritional yeast is different from regular yeast readily available at the store that I use for bread and pizza dough? Is it absolutely necessary in this recipe, or could it be omitted? Thanks!

        Hi Susan – Not a dumb question. Actually nutritional yeast is more of a cheese replacement, so not like the regular yeast. I typically find it in the organic condiments section of my grocery store, but you can also purchase it on Amazon. I would not recommend omitting this, because it adds the cheesy flavor that you want included in a quiche. Let me know how you like this recipe if you give it a try. Enjoy!

      Do you defrost the pie crust first or should it still be frozen when you put in oven with filling?

        Hi Kelly – I would follow the instructions on your pie crust. Some will have you pre-bake for a bit before filling and others won’t, it just depends on the brand of crust. I hope you enjoy this recipe!
