This Butternut Squash Quiche is deliciously sweet and savoury, with a crispy almond flour crust, creamy eggs and layers of spinach, squash, sage and prosciutto. It’s dairy-free, gluten-free and perfect for a holiday brunch!

I could eat quiche for any meal of the day. We often make one for dinner and serve it with a side salad, and then pack away any leftovers for lunches the next day. A few of our favourites include this Mediterranean quiche, this crustless asparagus quiche and this air fryer quiche (mini quiches).

If you’re also a lover of quiche, you’ll want to try this butternut squash and spinach quiche. The salty prosciutto, fragrant sage and sweet squash go perfectly together.

It’s also simple to make. There’s no need to roast the squash before adding it to the quiche, and the grain-free almond flour crust comes together with a few simple ingredients. No need to roll any dough. Just mix it up and press the dough into your prepared dish.

It’s an impressive brunch dish without a tonne of work.

Details on a few ingredients

Butternut squash: You only need 2 cups of squash for this quiche so I usually buy a very small butternut squash. Smaller ones are also easier to peel and chop. The squash cubes should all be cut into 1/2-inch pieces so they cook quickly and evenly in the quiche. If you buy pre-cut squash, you may need to cut the pieces into smaller cubes.

Almond flour: I usually use superfine blanched almond flour as it has a nice texture for baked goods. Blanched almond flour is made with almonds that have had the skins removed. I haven’t tested this quiche crust with almond meal, which is made from unpeeled almonds and has a courser texture.

Sage: I like to use dried sage in the crust as it mixes into the dough easily and doesn’t discolour it. If I have it on hand, I’ll use two tablespoons of chopped fresh sage in the filling. If you don’t have fresh, you can just use two teaspoons of dried sage in the filling.

Prosciutto: This is thinly sliced cured ham. While you don’t have to cook it, I like to place pieces on top of the quiche and let it crisp up on top.

How to make butternut squash quiche

Assemble the dough for the crust and press it into a well-greased baking dish or pie plate. Bake for 10-15 minutes.

In a small bowl, whisk together the eggs, almond milk, salt and pepper.

Add the spinach, squash and sage to the baked crust and pour on the egg mixture.

Place pieces of torn prosciutto on top.

Bake for another 40-45 minutes, or until the squash cubes are tender.

Recipe variations

Short on time? Skip the crust and make this quiche crustless.

Replace the spinach with kale or arugula.

Use other herbs such as oregano, basil or rosemary.

If you don’t need this quiche to be dairy-free, you can add some cheese.

For a vegetarian version, just leave out the prosciutto.

What to serve with squash quiche

A simple green salad always works for me, or try this roasted beet and carrot salad to keep things seasonal.

You can’t beat crispy air fryer baby potatoes or air fryer potato wedges paired with a slice of quiche.

Load up on veggie sides with these air fryer green beans, radishes or turnip fries.

Add a few healthier chips to the side like these air fryer tortilla chips or air fryer kale chips!

Additional recipe tips and substitutions

While I used a 8 x 11 inch oval baking dish, you can use a 10-inch pie plate or oven safe skillet.

If you don’t need this recipe to be dairy-free, you can substitute dairy milk for the nut milk.

When you pour the egg mixture onto the crust, it’s going to overflow around the edges of the crust. This is totally fine. The egg mixture bakes into the crust and makes it extra crispy. Just be sure to grease your baking dish well.

I like to layer the spinach underneath the squash so it’s mostly covered in egg. If your spinach is on top, it may brown or even burn.

If you have leftovers, reheat them in the oven on a low heat so the crust gets crispy again. If you warm the quiche in the microwave, the crust will be soft.
