Sardine Flatbread Ingredients
For the Flatbread
- Almond Flour – Provides the flatbread structure and a keto-friendly base. Substitute with coconut flour if needed, but adjust the quantity due to its higher moisture absorption.
- Ground Flaxseed – Adds fiber and healthy fats to bind the dough; chia seeds can be used instead if desired.
- Baking Powder – Ensures a light texture; always check for freshness before using for optimal results.
- Sea Salt – Enhances the flavors throughout; distribute evenly for a balanced taste.
- Eggs – Binds the ingredients while contributing to the rich flavor of the flatbread.
- Olive Oil – Adds moisture and richness to the bread; can be swapped with melted coconut oil for a different flavor profile.
- Water – Achieves the right dough consistency; you may need to adjust the amount based on your desired texture.
For the Topping
- Sardines – The star of the dish, providing a savory depth of flavor; canned tuna or salmon can be used as an alternative.
- Kalamata Olives – Contributes saltiness and a lovely texture; green olives work if you prefer a milder taste.
- Capers – Adds a briny flavor that complements the sardines perfectly; feel free to skip if you want a subtler tapenade.

- Lemon Juice – Brightens up the flavors; if you’re in a pinch, vinegar can serve as a substitute.
- Fresh Parsley – Brings a vibrant freshness and color to the tapenade; consider switching with basil or cilantro for a different twist.
Step‑by‑Step Instructions for Sardine & Olive Tapenade Keto Flatbread
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature will ensure the flatbread bakes evenly, achieving a perfect golden crust. While the oven heats up, take a baking sheet and line it with parchment paper to prevent sticking and make cleanup a breeze.
Step 2: Mix Dry Ingredients
In a mixing bowl, combine almond flour, ground flaxseed, baking powder, and sea salt. Whisk these dry ingredients together until they are well blended and free of any lumps. This step lays the foundation for your delicious Sardine & Olive Tapenade Keto Flatbread, ensuring a uniform texture throughout.
Step 3: Combine Wet Ingredients
In a separate bowl, whisk together the olive oil, eggs, and water until fully blended. This mixture adds moisture and richness to the dough, which is essential for a pleasant flatbread texture. Take care to blend well, ensuring the eggs are incorporated without any streaks for the best final product.
Step 4: Form the Dough
Gradually add the wet ingredients into the dry mixture, stirring until a cohesive and slightly sticky dough forms. Use a spatula or your hands to combine everything thoroughly. You want the dough to hold together but remain soft enough for shaping, making sure all ingredients are evenly distributed throughout.
Step 5: Shape the Flatbread
Transfer the dough onto the prepared baking sheet. With clean hands, gently press it into a disc about 1/4 inch thick. Aim for an even thickness to promote uniform baking, ensuring the edges are shaped neatly. This is the base of your savory Sardine & Olive Tapenade Keto Flatbread, ready to rise in the oven.
Step 6: Bake
Place your baking sheet in the preheated oven and bake for 15–20 minutes. Keep an eye on it, looking for golden edges and a firm center. This step is crucial as it transforms the wet dough into a delicious flatbread, giving it a slightly crisp exterior and tender interior.
Step 7: Prepare the Tapenade
While the flatbread is baking, prepare the sardine and olive tapenade. In a food processor, combine sardines, Kalamata olives, capers, fresh parsley, lemon juice, and minced garlic. Pulse until you’ve achieved a chunky, spreadable consistency, balancing flavors to create a heavenly topping for your warm flatbread.
Step 8: Assemble and Serve
Once the flatbread is slightly cooled, spread the tapenade generously over the top. Using a sharp knife, slice the flatbread into portions and serve warm. Enjoy the delightful combination of flavors and textures that comes with this Sardine & Olive Tapenade Keto Flatbread, perfect for a quick meal any time of day.

Sardine & Olive Tapenade Keto Flatbread Recipe FAQs
How do I select the best sardines for this recipe?
Absolutely! When choosing sardines, look for those packed in olive oil or water without added preservatives. Also, check for firm, whole fish without dark spots or strong off-odors. Canned sardines in a glass jar can also be a great alternative, as they often contain higher quality fish.
How should I store leftover flatbread and tapenade?
For the flatbread, store it in an airtight container in the fridge for up to 3 days to keep it fresh. The tapenade can be kept in a separate airtight container in the fridge for up to 5 days. If you want to prolong their shelf life, consider freezing the flatbread wrapped tightly in plastic wrap for up to 2 months, and thaw in the fridge overnight before reheating.
Can I freeze the sardine & olive tapenade keto flatbread?

What can I do if my flatbread is too crumbly?
If your flatbread turns out crumbly, it might be too dry. Next time, try slightly reducing the almond flour or increase the moisture by adding a bit more water or olive oil. Remember to mix until just combined; over-mixing can lead to crumbles as well!
Is this recipe suitable for people with specific dietary restrictions?
Very! This flatbread is keto-friendly and gluten-free, making it an excellent option for those avoiding wheat. If you have nut allergies, try substituting the almond flour with a seed-based flour like sunflower seed flour.
