Purple Sweet Potato Pie
Add a pop of color to your holiday dessert table with a Purple Sweet Potato Pie. Nestled on a homemade gingersnap crust, this delicious custard pie is a show stopping alternative to pumpkin on Thanksgiving and Christmas.
It’s Monday, the first day of a new workweek and the first day of my new job. I woke up ready to jump headfirst into my role only to find I was out of coffee, my corporate email had yet to be set up and my laptop wasn’t functioning properly. Mondays don’t get any more Monday than this one. Still, I won’t let this deter my excitement. Sharks don’t care if they have caffeine and access to Outlook, nor do they care what day it is. They do scary shark stuff 7 days a week regardless. Monday or not, they’re seizing the day, terrifying beachgoers and biting people with their 5 rows of teeth.
I can think of a few people I’d like to bite and it’s no coincidence they all happen to work for my previous employer. But since biting fellow team members is frowned upon by HR, I resigned and redirected my biting urges from people to pie. Besides, sinking my teeth into a creamy slice of pie tastes a lot better than sinking them into the limbs of corporate executives. Especially when that pie is Purple Sweet Potato Pie.
Naturally colored and antioxidant packed, purple sweet potatoes are the shining star of this perfect-for-fall pie. Nestled in a nutty gingersnap crust, the custard filling is made with mashed purple sweet potatoes and warm spices. A unique alternative to traditional sweet potato pie, the taste, texture and stunning purple hue will wow guests this holiday season. Have a nibble or chomp on a slice like a shark going in for the attack; big bites or small, you’ll adore this delicious twist on dessert.
Before sharing the recipe for Purple Sweet Potato Pie, here are a few tips to help you out:
If you’re wondering where to buy purple sweet potatoes, check grocery stores such as Whole Foods, Fresh Market and Sprouts. The purples sweet potatoes tested in the recipe were the famous Stokes brand that I found at Sprouts.
Thin, crispy gingersnaps work best for the crust. I used a private label brand from my local grocery store.
To make your own purple sweet potato puree, pierce purple sweet potatoes all over with a fork then bake at 400 degrees for approximately 1 hour. After cooling, discard skins and puree flesh in a food processor.
Bake pie until the edges set but the center is still a bit jiggly. My pie baked 45 minutes at 325 degrees.
You can make the crust 1 day in advance. Cover and store at room temperature until ready to use.
How to Store Purple Sweet Potato Pie
To store pie, cover tightly with plastic wrap then refrigerate up to 5 days.
Pie can be made ahead and frozen up to 3 months. After baked pie has cooled completely, wrap tightly with plastic wrap then with aluminum foil and freeze. Thaw overnight in the refrigerator before serving.
