One of the first grain-free pizza crust players to hit the market was Simple Mills Pizza Dough, and this mix—made from a combo of almond and coconut flour, flax, dried cauliflower, herbs, and other completely paleo and vegan ingredients—is still a hit. Bonus: At this point, Simple Mills extensive line of grain-free products can be found at loads of grocery stores.

A personal favorite, I try to always keep my freezer stocked with a Cappello's crust (or one of their frozen grain-free premade pizzas or pastas). With eggs and almond flour as the main ingredients, it has a slightly richer, more buttery flavor than some of these other picks. You can typically find these at Whole Foods, and if not, they're online.

Thrive Market's Paleo Pizza Crust Mix consists of almond flour, potato starch, and tapioca starch. And while you have to add in a fair number of ingredients at home (eggs, honey, olive oil, salt, and water), it's well worth the effort. Pro tip: When baked as recommended, it turns out a little soft, so keep in a few extra minutes if you like things crispy.  

For a while I was frustrated with Caulipower because their original vegan-friendly crust contains brown rice flour, and I try to steer clear of grains. But then they launched their Cauliflower Paleo Pizza Crust (which also features almond flour and eggs) and all was right in the world. Bonus: A serving has 20% of your recommended daily intake of vitamin C.

When I recently came across these PlantPower Pizza Crusts at my local grocery store and took a look at the nutrition facts, my first reaction was, whoa, only 4 grams of carbs per crust! Made with fresh cauliflower, eggs, Parmesan cheese, nutritional yeast, and herbs, this is one of the few keto-friendly crusts out there—plus, it's delicious, high in protein, and packs 50% of your RDI for vitamin C and 25% of your calcium.

Mikey's is another company that's nailed all things grain-free—and amazingly, without cauliflower! Their Grain-Free Pizza Crust, made predominantly of eggs, almond flour, and coconut flour, is also quite low in carbs (just 9 grams) and higher in fiber (4 grams) than any of these other pics. If you haven't tried them yet, their grain-free Pepperoni Pizza Pockets are also delightful.
