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.

Description

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


Ingredients

  • 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
  • 810 oz frozen chopped spinach, thawed and drained*
  • 1 teaspoon sea salt, to taste 
  • ¼ teaspoon freshly ground black pepper, to taste
  • 3 large eggs
  • 1/3 cup egg whites (or 3 additional eggs)
  • 2/3 cup unsweetened oat milk (or other non-dairy milk)
  • 2 Tablespoons nutritional yeast
  • fresh chopped thyme, for garnish

Instructions

  1. Preheat oven to 400°F. 
  2. 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.
  3. 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. 
  4. 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. 
  5. 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.
  6. Store leftovers in the fridge for up to 5 days. Reheat in the oven or toaster oven.

Notes

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

  1. Loved this recipe, Brittany! I made this for my two daughters and my husband and they absolutely loved it! (Even our pups snuck a bite 😉

  2. Made this recipe yesterday and it was awesome! I used a deep dish pie crust so I increased the eggs, egg whites, and oat milk a bit – my boyfriend just about ate the whole thing in one sitting! Thanks so much for the recipe.
