Yes, this sauce is naturally gluten-free, which is one of the reasons I love it! The spinach, scallions, garlic, pesto, and cheese are all gluten-free on their own. However, if you're pairing it with pasta, just be sure to choose a gluten-free variety to keep the whole dish gluten-free. I’ve made this sauce with gluten-free pasta many times, and it’s just as delicious—no one can tell the difference! So, go ahead and enjoy it without any worries.
