Step‑by‑Step Instructions for Gluten Free Everything Mashed Potato Flatbread
Step 1: Prep Potatoes
Begin by peeling and chopping 2 medium Russet potatoes into even chunks. Boil them in salted water for 15-20 minutes, or until they are fork-tender. Drain and let the potatoes cool completely before mashing until smooth. Alternatively, you can use about 2 cups of prepared mashed potatoes for a quicker start on your mashed potato flatbread.
Step 2: Mix Ingredients
In a large mixing bowl, combine the cooled mashed potatoes with 4 tablespoons of melted butter and 1 egg, mixing until the mixture is smooth and well-blended. Gradually add in 1 cup of rice flour, 1/4 cup of corn starch, 1 teaspoon of baking powder, and 1/2 teaspoon of salt, stirring until a soft, cohesive dough forms.
Step 3: Chill Dough
Once your dough is well mixed, wrap it tightly in plastic wrap and place it in the refrigerator. Allow it to chill for about 30 minutes. This resting period will help enhance the texture of your gluten-free everything mashed potato flatbread, allowing for easier shaping later on.
Step 4: Shape Flatbreads
Preheat your oven to 450°F (230°C) while the dough chills. Remove the dough from the refrigerator and divide it into 8 equal pieces. Roll each piece into a ball, then flatten them gently using floured fingers to form a disk about 1/2 inch thick, ensuring you maintain an even shape for consistent cooking.
Step 5: Top and Bake
Line a baking sheet with parchment paper to prevent sticking, then place the flatbreads on the sheet. Brush each top with melted butter and generously sprinkle with your everything topping mix, including poppy seeds, sesame seeds, garlic, and onion. Bake for 15 minutes or until the tops are golden browns, then brush with melted butter once more for an extra bit of flavor.

How to Store and Freeze Mashed Potato Flatbread
Fridge: Store the flatbread in an airtight container for up to 3 days. This helps maintain its soft texture and flavor without drying out.
Freezer: For longer storage, wrap the flatbreads tightly in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to 2 months.
Reheating: To enjoy, simply thaw the flatbreads in the refrigerator overnight, then reheat in the oven or toaster for a few minutes until warmed through and crisped up again.
