Gluten-Free Casein-Free Pizza

Amy's Kitchen produces a rice crust soy-based mozzarella and ricotta "cheeze" spinach pizza that's gluten-free and contains no dairy ingredients. The 14-inch pizza can feed two people.

The company tests its products in-house to make sure they contain less than 5 parts per million (ppm) of gluten.

Brand-new company BOLD Organics is making four different GFCF frozen pizzas: "cheese," veggie lovers, meat lovers and deluxe. All use a vegan cheese substitute based on tofu, and two of the pizzas (cheese and veggie lovers) also qualify as vegan gluten-free frozen pizzas.

BOLD Organics holds gluten-free certification from the Celiac Sprue Association, which requires products test below 5 parts per million in gluten cross-contamination. The company also holds organic and non-GMO certifications.

Whole Foods makes a GFCF frozen pizza under its 365 in-store brand label. The pizza includes no cheese substitutes; instead, it's topped with roasted vegetables.

The company labels this pizza as containing "no gluten ingredients" rather than calling it gluten-free because it's produced in a plant that also makes gluten-containing items. Whole Foods reports that the plant uses "good manufacturing procedures" to avoid cross contamination.

Glutino's individual-sized brown rice pizza is topped with spinach and soy "cheese" made with tofu. The dairy-free GFCF pizza does contain eggs.

Glutino tests its products to contain fewer than 20ppm of gluten.

Ian's Natural Foods offers a GFCF frozen pizza with a French bread crust that's aimed straight at kids who eat GFCF. The pizza substitutes "soy cheesy" for mozzarella cheese. Ian's GFCF Pizza was a finalist in the 2012 About.com Gluten-Free Readers' Choice Awards Best Gluten-Free Frozen Pizza category.

Each 8-ounce package of Ian's pizza includes two slices. Ian's tests its products to contain fewer than 20ppm of gluten.

If you want to make your own GFCF pizza using a pre-made crust, several of these will suit your diet. Udi's Gluten-Free Foods, Gillian's Foods, Glutino and Kinnikinnick all make gluten-free casein-free frozen pizza crusts. Some contain eggs and soy, though, so choose carefully if you're avoiding those ingredients as well.

You can top these GFCF pizzas with rice- or soy-based "cheese" from the supermarket — just make sure the faux cheese product doesn't contain casein, because some do.
