Spaghetti Squash Gratin
Creamy spaghetti squash gratin with pancetta and gorgonzola is topped with panko and baked until golden for an easy low carb side dish.
Spaghetti squash and cauliflower rice. My two favorite master-of-disguises in the low carb eating world.
Something about their texture and bland flavor makes them the perfect canvas for creating something that seems horribly bad for you, yet somehow remains semi-healthy.
This spaghetti squash gratin is no different and does not disappoint.
I’m not claiming it’s 100% healthy, seeing as there is cheese, milk and pancetta in it, but it’s definitely a lot less carbs than your standard potato gratin and for me, that’s a victory.
I can attest to its deliciousness because John thinks it’s amazingly good and for him to say that about a vegetable gives me the green light :).
I can’t take full credit for creating this beautiful side dish.
There’s a small restaurant John and I like to go to occasionally and they had something similar to this as an appetizer/dip on their menu.
It was so good, we couldn’t stop eating it!
Creamy and savory with a little crunch from the panko. My new favorite way to eat spaghetti squash ;).

Follow recipe instructions up until the panko topping and store in the refrigerator, place panko topping on just before baking.
