- Wooden spoon
- Heavy-bottomed skillet or Dutch oven
- Baking stone or inverted baking sheet
- Parchment paper

- Baking stone: Helps achieve a crispy crust by mimicking traditional baking methods.

Ingredients
To make the delicious Caramelized Onion and Feta Flatbread, gather the following ingredients:
For the Dough
- 3 ½ cups (420g) Bread Flour: Provides a chewier, more structured crust, but all-purpose flour works well in a pinch.
- 2 ¼ teaspoons (1 packet) Instant Yeast: The leavening agent that gives our dough its light, airy texture.
- 1 ½ teaspoons Granulated Sugar: A little food for the yeast to help it activate and add a touch of flavor.
- 2 teaspoons Kosher Salt: Crucial for flavor; it controls the yeast and strengthens the gluten structure.
- 1 ½ cups Warm Water (105-115°F / 40-46°C): The perfect temperature to activate the yeast without harming it.
- 2 tablespoons Extra Virgin Olive Oil: Adds richness, flavor, and softness to the dough.
For the Topping
- 3 large Yellow or Sweet Onions: These varieties contain more sugar, making them ideal for achieving deep, sweet caramelization.
- 3 tablespoons Unsalted Butter: Adds a rich, nutty flavor to the onions as they cook.
- 2 tablespoons Extra Virgin Olive Oil: Used for both caramelizing the onions and brushing the dough.
- 1 teaspoon Kosher Salt: To draw out moisture from the onions and season them perfectly.
- ½ teaspoon Black Pepper: Freshly ground for the best flavor.
- 1 cup (about 5 oz) Crumbled Feta Cheese: Use a block of feta packed in brine and crumble it yourself for superior flavor and texture compared to pre-crumbled varieties.
- 1 tablespoon Fresh Thyme Leaves: (Optional) Adds a wonderful earthy, floral note that complements the onions beautifully.
- Balsamic Glaze: (For serving) A drizzle at the end provides a sweet and tangy finish that ties all the flavors together.
How to Make Caramelized Onion and Feta Flatbread
Step 1: Activate the Yeast
- In your stand mixer bowl or large mixing bowl, combine warm water, instant yeast, and granulated sugar. Whisk gently until combined.
- Let it sit for 5–10 minutes until foamy. If there’s no foam after this time, you may need new yeast.
Step 2: Mix the Dry Ingredients
- In another bowl, whisk together bread flour and kosher salt. This helps distribute salt evenly so it doesn’t affect yeast prematurely.
Step 3: Combine and Knead (Stand Mixer Method)
- Attach dough hook to your stand mixer. With low speed running, gradually add flour mixture into wet ingredients until combined.
- Add olive oil; increase speed to medium-low for about 6–8 minutes until smooth.
Step 4: Combine and Knead (By Hand)
- If mixing by hand, stir half flour into yeast mix with wooden spoon until combined.
- Add remaining flour along with olive oil; mix until shaggy dough forms then knead on floured surface for about 10–12 minutes.
Step 5: First Rise (Proofing)
- Shape dough into a ball; grease mixing bowl lightly with olive oil then place dough inside turning once to coat top.
- Cover with towel or plastic wrap; let rise in warm area until doubled in size (60–90 minutes).
Step 6: Prep the Onions
- Peel onions; cut in half from pole to pole then slice thinly into half-moons.
Step 7: Start the Sauté
- Melt butter with olive oil in heavy-bottomed skillet over medium-low heat.
Step 8: Cook Low and Slow
- Add sliced onions along with salt and black pepper into pan; stir to coat in fat.
- Cook slowly stirring every 5–7 minutes without rushing—this is key for proper caramelization.
Step 9: The Caramelization Process (30–45 Minutes)
- First 10 minutes: Onions soften & become translucent.
- Next 10–15 minutes: Onions turn pale golden yellow while releasing liquid—look out for brown bits forming on bottom!
- Final 10–20 minutes: Onions deepen in color becoming jam-like; stir frequently now to avoid burning.
Step 10: Finish
Once onions are deeply caramelized & jammy remove from heat; stir in fresh thyme if using.
Step 11: Preheat Your Oven
Preheat your oven to 450°F (232°C), placing baking stone or inverted baking sheet inside on middle rack.
Step 12: Divide and Shape Dough
Once risen gently punch down air; transfer dough onto floured surface dividing into two equal pieces resting each piece for about five minutes.
Step 13: Roll It Out
Roll one piece at a time into rustic shape about ¼-inch thick placing on parchment paper.
Step 14: Top the Flatbread
Brush with olive oil; spread half cooled caramelized onions leaving edge border & sprinkle half crumbled feta on top.
Step 15: Bake to Perfection
Slide parchment onto preheated stone/sheet & bake for about 12–15 minutes until golden brown crust forms & feta slightly melts.
Step 16: Repeat
As first flatbread bakes assemble second one on separate parchment paper.
Step 17: Garnish & Serve
Allow baked flatbread cooling slightly before drizzling balsamic glaze over top then slice & serve immediately!

- Use Fresh Ingredients: Opt for fresh onions and high-quality feta cheese to enhance flavor.

- Don’t Skip the Preheat: Preheating your oven ensures that the flatbreads bake evenly, leading to a crispy crust.

- Experiment with Herbs: Try different herbs like rosemary or oregano alongside thyme for varied flavors.

Common Mistakes to Avoid
When making Caramelized Onion and Feta Flatbread, a few common mistakes can hinder your results. Here are some pitfalls to watch out for:
- Using Cold Water: Always use warm water to activate the yeast effectively. Cold water can prevent the yeast from blooming, leading to a dense dough.
- Rushing the Caramelization: Patience is key when caramelizing onions. Cooking them too quickly can result in burnt bits rather than sweet, rich flavors. Cook them low and slow for the best results.
- Neglecting Dough Resting Time: Allowing your dough to rest after kneading is essential for gluten relaxation. Skipping this step can make shaping difficult and lead to a tough flatbread.
- Overloading on Toppings: While it’s tempting to add lots of toppings, remember that too much can make the flatbread soggy. Stick to the recipe amounts for the best texture and flavor.
- Not Preheating Your Baking Surface: A hot baking stone or sheet is crucial for achieving a crispy crust. Don’t skip preheating; it makes a significant difference in texture.

Storage & Reheating Instructions
Refrigerator Storage
- Store leftover flatbread in an airtight container.
- It will stay fresh for up to 3 days in the refrigerator.
Freezing Caramelized Onion and Feta Flatbread
- Wrap each flatbread tightly in plastic wrap or aluminum foil.
- Freeze for up to 2 months for best quality.
Reheating Caramelized Onion and Feta Flatbread
- Oven: Preheat your oven to 350°F (175°C). Place the flatbread directly on the rack or on a baking sheet for about 10 minutes until heated through.
- Microwave: Heat individual pieces on a microwave-safe plate for about 30 seconds. This method may soften the crust slightly.
