The Hand Off: Spaghetti Squash with Herbed Leek Sauce

2010 October 21

by Brianna Bain

Squash is where it’s at this week!  I run towards the next hand off taking the butternut squash and the delightful medley of herb’s from Sarah’s Herb Roasted Roasted Chicken as a spring board into this week’s dish. As I mentioned in Tuesday’s post I planned to make a dish in the image of fetuccini alfredo that would bring glory to the spaghetti squash. This endeavor also came with the added adventure of supplying a satisfying meal to my Celiac (gluten allergy) and lactose intolerant (dairy allergy) family members. Ultimately materializing from this vision – a baked spaghetti squash with a creamy herbed leek sauce that proved a winner in all categories!

For my sauce I needed a vegetable that could lend itself to a certain creaminess, I turned to the trusty leek! Leeks posses a magical buttery goodness when cooked with a little oil and salt- a perfect foundation for a vegetable white sauce to top my veggie noodles, aka: spaghetti squash. Traditional alfredo sauce calls for a lot of butter, a lot of Parmesan cheese, garlic, salt and parsley. Since I had the creaminess covered with the leeks I wanted to boost the herb flavor with more than parsley alone. I added a trio of  fresh herbs from my garden and turned up the zing by adding some lemon juice and zest. It’s a far cry from any alfredo sauce but as promised I am creating a dairy free variation  of a traditional creamy sauce.

This dish was extremely easy to create and shop for; an ideal combination for  good vegetarian dishes.  In gathering ingredients for this dish from my local markets I felt very lucky to be able to source organic and seasonal  produce while maintaining creative freedom.  This dish is simple, easy, inexpensive, and palate pleasing all while bearing the blue ribbon as a trifecta champion in the vegetarian, gluten and dairy free categories!

I found many suggestions for how to cook the actual Spaghetti Squash and I have tried a few. My most successful attempt was cutting the squash in half and cooking it on the stove top with a few inches of water in a large pot with a lid. The cooking process only took 25 minutes, the squash was moist and  practically falling right out of it’s shell. While the method I have used above  is recommended by most of my cookbooks, it did  take 1 hour and there were still parts of the squash that were not  as evenly cooked through in comparison to my stove-top trial. Next time I might try adding a little water to the oven dish to assist in a more even heat.  As for the sauce, it is quite lemony. That is okay by me, but others may want to omit the lemon juice and stick to just using the zest or visa-versa. Take it slow and taste it after you add the the zest. If you aren’t feeling up to creating the Leek sauce I would recommend some good old fashioned marinara. Treat the squash just as you would any pasta. I hope my adventures in spaghetti squash have broadened your horizons in squash this season. Leave a comment, tell me about your squash trials or other interesting Fall recipes!

Until next time —

Squash it up!
