These Spooky Purple Sweet Potato Fries are a fun and tasty Halloween treat, with a trio of dips for these “witch fingers”! Perfect for dipping and snacking during the season’s festivities!

There’s nothing more fun than spooky Halloween snacks during the season, and these Spooky Purple Sweet Potato Fries are a satisfying, delicious, and healthy way to celebrate!
I was excited to create a Halloween treat that was silly and spooky for the kids this month, and these were the perfect way to do just that!
Sprouts Farmers Market has all my favorite seasonal items to make awesome Fall treats at home. We picked up these amazing purple sweet potatoes from Sprouts, along with everything else we needed to re-stock our pantry staples for the season. We picked up all of the dried herbs and spices for the witch fingers and trio of dips, plus fresh cilantro, avocados and spinach!



The kids had a blast making the various dips, and of course taste testing! It was hard to pick a favorite. We ended up creating a tasty variety: from a tangy and herb-y homemade ranch dressing, a twist on guacamole with the avocado-spinach-cilantro dip, and a sweet-spicy ketchup with red beet powder for extra nutrition and a cool purple color — it’s a dip lover’s dream!
I made a less spicy version of the Spicy Beet Ketchup for them, and they loved the purple, vibrant hue from the Sprouts Organic Red Beet Powder. So fun!
If you’ve never made ranch at home before, I hope you can give this Herb Ranch a try! It’s so easy and so delicious. The tangy lemon juice and the dried herbs give this dressing that signature ranch flavor.
And last but not least, we of course had to have an avocado dip! Blended with spinach and cilantro, this green dreamy dip has lots of hidden veggies and tons of flavor.
