Butternut Quiche with Caramelized Onions

This beautifully flavoured quiche is a wonderful dish for a crowd or a special Sunday morning brunch. I recently served this up to a group at a retreat, and they were SO in love that they have inspired me to share the recipe on the website.
You will need a bit of time to caramelize the onions and roast the squash, but the steps in this dish are so worth the time commitment 😉
As always, feel free to modify the recipe to suit your taste buds and preferences. You can easily swap out the butternut for a different squash or add sautéed mushrooms and/or sun-dried tomatoes. Keep in mind that because the onions are caramelized, there is a bit of a sweet taste to this quiche, so modifying too much might work against you.

Butternut Quiche with Caramelized Onions

Serves 6
Dairy-free, Gluten-free

1 medium onion, sliced
1 Tbsp avocado oil
2 Tbsp balsamic vinegar
1/2 small butternut squash, cut into 1/2” cubes
2 Tbsp coconut oil
Salt & pepper
7 eggs
1/4 cup full fat coconut milk
1/2 teaspoon salt
½ tsp dried sage
1/4 tsp dried thyme
¼ cup nutritional yeast
1 cup packed fresh spinach, chopped
Fresh parsley, green onion, tomato slices, and/or avocado for serving

  • Preheat oven to 400 degrees.

  • Slice one large onion and place into a large saucepan. Add avocado oil and balsamic vinegar. Cook the onion slices on medium/high, stirring frequently. Once the onions start to get translucent, turn the heat to medium/low and cook until they start to caramelize. This will take roughly 30 minutes.

  • While the onions are cooking, cut the butternut squash into 1/2″ cubes and place in an 8x8 glass dish, coat with 2 Tbsp coconut oil and season with salt and pepper.

  • Roast the squash for 20 - 25 minutes, until slightly softened.
    Once squash is done, lower the oven temperature to 375 degrees.

  • Let the squash and onions cool slightly. Combine the eggs, coconut milk, spinach, dried herbs, butternut squash, and caramelized onions in a large bowl. Mix well then pour back into your 8x8 glass dish still greased from the squash.

  • Bake for 45-55 minutes, or until the centre of the quiche is set - you can check by simply wiggling the pan slightly to see if the eggs are firm. Serve with parsley, green onions, fresh tomato, and/or sliced avocado.
