Ingredients
Servings
6
- 1 1/2 cups gluten-free all-purpose flour blend (ensure xanthan gum included)
- 1 teaspoon baking powder
- 1/2 teaspoon fine sea salt
- 1/2 cup warm water (110°F/43°C)
- 1 tablespoon olive oil, plus extra for brushing
- 1 medium zucchini, thinly sliced into ribbons using a vegetable peeler
- 2 cups fresh basil leaves, packed
- 1/4 cup extra virgin olive oil
- 1 clove garlic, minced
- 1 tablespoon lemon juice
- 1/4 teaspoon sea salt
- 1/4 teaspoon freshly ground black pepper
- Optional
- 1 tablespoon nutritional yeast (for slight cheesy flavor, dairy-free)
Instructions
-
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
-
In a medium bowl, whisk together the gluten-free flour blend, baking powder, and salt.
-
Add warm water and 1 tablespoon olive oil to the dry ingredients. Mix until a soft dough forms. If dough is too sticky, add a little more flour, 1 tablespoon at a time.
-
Place dough on a lightly floured surface and gently knead a few times until smooth. Roll dough out into a roughly 10x12 inch rectangular shape about 1/4 inch thick.
-
Transfer the rolled dough to the prepared baking sheet. Lightly brush the surface with olive oil.
-
Bake the flatbread in the oven for 10 minutes or until edges just start to turn golden.
-
Meanwhile, prepare the nut-free basil pesto: In a food processor, combine basil leaves, garlic, lemon juice, salt, pepper, and nutritional yeast if using. Pulse to roughly chop.
-
With the motor running, slowly drizzle in the olive oil until the pesto is smooth but not too watery. Adjust seasoning if needed.
-
Remove the flatbread from the oven. Spread the basil pesto evenly over the warm flatbread.
-
Arrange zucchini ribbons decoratively on top of the pesto layer.
-
Return the flatbread to the oven and bake for an additional 5 minutes until zucchini is tender but still vibrant.
-
Let the flatbread cool for 5 minutes, then slice into squares or rectangles.
-
Serve warm or at room temperature as an appetizer or side dish.

Customize your Gluten-Free Zucchini and Basil Pesto Flatbread with these ingredient swaps to fit your dietary needs or pantry availability:
- Gluten-Free Flour Blend: Use any certified gluten-free all-purpose flour blend containing xanthan gum. For grain-free options, try almond flour with a binding agent like psyllium husk powder, though texture may differ.
- Baking Powder: Verify gluten-free status or substitute baking soda with cream of tartar.
- Olive Oil: Substitute with avocado or melted coconut oil for a different flavor, maintaining dairy-free and paleo compliance.
- Nut-Free Basil Pesto: This recipe uses nut-free pesto; if nuts are acceptable, swap with traditional pesto containing pine nuts or walnuts for richer flavor.

Allergen Overlap Note
While our gluten-free recipes on Freeflourish are carefully crafted to avoid gluten-containing ingredients, please be aware of potential cross-contamination risks, especially if you have severe allergies or sensitivities. Many recipes also cater to diverse dietary needs, including dairy-free, nut-free, vegan, and paleo options, but ingredients and preparation surfaces might inadvertently come in contact with allergens.
To keep your meals safe:
- Use dedicated gluten-free ingredients and always verify labels for hidden gluten or other allergens.
- Thoroughly clean cooking utensils, cutting boards, and surfaces before preparation to avoid cross-contact with gluten, nuts, dairy, or other common allergens.
- Store gluten-free flours, grains, and baking supplies separately when managing several dietary restrictions.
- If dining out or sharing food, communicate your allergen needs clearly to prevent accidental exposure.
Our recipes span categories like Breakfast, Lunch, Dinner, Desserts, Snacks, Soups & Salads, Gluten-Free Baking, Quick & Easy, Family-Friendly, and Holiday & Seasonal, including tags like glutenfree, dairyfree, nutfree, vegan, vegetarian, and more. This broad variety supports many dietary preferences, but mindful preparation and ingredient sourcing are essential for allergen safety and enjoying delicious meals without compromise.
Texture Expectations
Gluten-free baking textures often differ from traditional wheat recipes due to the absence of gluten. In this Gluten-Free Zucchini and Basil Pesto Flatbread, expect a tender but slightly crisp crust with a delicate, somewhat crumbly crumb compared to conventional flatbreads. The gluten-free all-purpose flour blend ensures a stable structure, though this flatbread will not have the classic chewiness of wheat-based dough.
The initial bake creates a firm base with lightly golden edges, offering a mild crunch that contrasts beautifully with the fresh, moist toppings. Adding olive oil to the dough and brushing the surface before baking helps retain moisture, preventing dryness or brittleness.
Topping the flatbread with nut-free basil pesto and zucchini ribbons before a short second bake softens the zucchini while keeping its bright texture. This combination delivers a pleasing textural contrast between the soft, tender flatbread and fresh vegetable toppings.
Texture may vary slightly depending on the gluten-free flour blend used—some high-starch blends yield a more cake-like crumb, while those with xanthan gum or psyllium husk offer more chew and stretch. For a firmer crust, bake longer initially or roll the dough thinner; for a softer, focaccia-like bite, leave it a bit thicker.
This recipe’s texture fits well with family-friendly and quick & easy meals, offering a comforting yet light base that highlights fresh flavors and avoids heaviness common with grain-based flatbreads. Serve warm for the best balance of softness and crispness or at room temperature as a tender, flavorful snack.
Dining With Non Gf Family Note
When cooking for both gluten-free and non-gluten-free family members, careful planning helps avoid cross-contamination and ensures everyone enjoys meals safely and happily. Here are practical tips to foster coexistence in family dining:
- Designate Separate Cooking Areas and Utensils: Use clearly labeled or separately stored cutting boards, toasters, colanders, and utensils for gluten-free prep to prevent gluten residue.
- Clean Surfaces Thoroughly: Wipe countertops, stovetops, and prep areas with appropriate cleaners before making gluten-free dishes to remove gluten traces.
- Cook Gluten-Free Foods First: Prepare gluten-free items before handling gluten-containing foods to limit airborne or surface contamination.
- Use Separate Storage Containers: Keep gluten-free ingredients sealed and stored apart from gluten-containing products to avoid accidental mixing.
- Communicate Clearly: Educate non-gluten-free family members on maintaining gluten-free zones and respecting dietary needs, especially with snacks and shared dishes.
- Label Leftovers: Clearly mark gluten-free foods in the fridge or freezer to prevent confusion at mealtime.
- Serve Separately: Use different plates for gluten-free dishes rather than shared platters to prevent contact.
- Choose Naturally Gluten-Free Recipes: Focus on meals from categories like Breakfast, Soups & Salads, Family-Friendly Dinners, and Gluten-Free Baking which use naturally gluten-free ingredients.
- Opt for Quick & Easy or One-Pot Recipes: Recipes tagged as quickrecipes, onepot, or 30minutesorless reduce contamination risk by limiting prep steps and utensils.
Integrating these tips makes gluten-free dining enjoyable and safe for all family members, regardless of dietary preferences.
