Blind baking filo pastry is a technique that involves partially baking the pastry before adding the filling. This helps ensure the pastry is crispy and avoids a soggy bottom crust. But do you really need to blind bake filo every time? Here’s a look at when blind baking is necessary and tips for the process.
When to Blind Bake Filo Pastry
Blind baking isn’t always required with filo dough. Here are some instances when it’s a good idea to blind bake the filo:
- Using moist fillings like fruit, creamed mixtures, or cheese that release liquid during baking. Blind baking helps prevent a soggy bottom.
- Making dishes that require a long bake time. The filo will get a head start on crisping up.
- If you plan to re-heat the dish later. Blind baked filo is less likely to get soggy when reheated.
- For an extra crispy filo crust. Blind baking crisps up the dough more than a single bake.
You can skip blind baking for drier fillings like nuts, breadcrumbs, diced meats, or for dishes with shorter bake times. But when in doubt, blind baking provides insurance against mushy filo.
How to Blind Bake Filo Dough
Here is a simple process for blind baking filo dough:
- Prepare the filo pastry according to recipe instructions. This may involve thawing frozen dough, separating sheets, or brushing with butter or oil.
- Line a baking pan with enough filo sheets to cover the bottom and sides. Brush each sheet with butter or oil.
- Prick the filo several times with a fork to allow steam to escape.
- Bake at 375°F for 8-10 minutes, until lightly browned. Watch closely to prevent burning.
- Remove from oven and allow to cool before adding filling and returning to oven.
The baking time will vary based on the shape and size of your dish. Smaller pastries or thin sheets may only need 5-7 minutes. Larger pans or thicker layered filo may need 12-15 minutes.
Tips for Blind Baking Filo
Follow these tips for best results when blind baking filo dough:
- Butter, oil, or spray each sheet well so it doesn’t dry out in oven.
- Avoid overcrowding filo in pan, leave room between sheets for air flow.
- Prick thoroughly with a fork before baking to allow steam to escape.
- Watch closely to prevent burning. Filo can go from golden to burnt quickly.
- Cool partially baked filo before filling to prevent melting fillings.
- Keep unused filo covered with plastic wrap and a damp towel to prevent drying.
How to Tell if Filo is Fully Baked
It can be tricky to tell when blind baked filo is ready. Here are a few signs to look for:
- Light golden brown color
- Filo sheets feel set and hardened
- Layers are visibly separated and flaky
- Crisp texture without burnt spots
Underbaked filo will seem soft, pale, and doughy. Overbaked filo turns dark brown and tastes burnt. Getting the right bake comes down to watching closely and testing a piece to get the texture right.
Can You Overbake Filo?
Yes, it’s definitely possible to overbake filo dough. Some signs you’ve gone too far:
- Dark brown or blackened spots
- A burnt smell
- Filo sheets are hard and brittle
If the filo is bordering on overdone, you may be able to trim off any burnt edges. But if the taste is bitter throughout, it’s best to start over.
To prevent burning, watch the blind baking filo closely and reduce oven temperature if needed. Bake just until set and lightly browned without charring the dough.
Should You Blind Bake Store-Bought vs. Homemade Filo?
Both store-bought and homemade filo pastry benefit from blind baking in the right circumstances. Store-bought dough tends to be thinner and more delicate than homemade. It may need a little less baking time to avoid burning. But the blind baking principles are the same.
Is There a Shortcut for Blind Baking Filo?
Unfortunately there are no good shortcuts for properly blind baking filo dough. Rushing the process often leads to disappointing results. Here are a couple things that won’t work:
- Microwaving – Makes filo gummy and soft instead of crisp.
- Partial baking – Leads to uncooked spot and soggy bottoms.
- High heat – Can burn exterior before inside is baked.
Allowing enough time for a proper blind bake really ensures the best texture and prevents filo failure. Have patience and bake it until lightly browned and flaky.
Common Problems When Blind Baking Filo
Here are some common issues that can pop up when blind baking filo dough and how to avoid them:
| Problem | Cause | Solution |
|---|---|---|
| Soggy or soft | Underbaked | Bake longer at lower temperature |
| Burnt spots | Overbaked | Watch closely, reduce temperature |
| Dry, cracked | Overhandled | Work quickly, keep damp towel on unused filo |
| Unpuffed | Sheets not layered properly | Leave space between filo for airflow |
Can You Freeze Blind Baked Filo Dough?
Yes, blind baked filo dough can be frozen for convenience. Here’s how:
- Let blind baked filo cool completely after baking.
- Wrap tightly in plastic wrap then foil. Try to remove excess air.
- Label package with contents and freeze up to 2-3 months.
- Thaw overnight in fridge before using.
The pre-baked filo sheets or crusts can go straight from freezer to oven after thawing. This saves time down the road.
Recipes that Benefit from Blind Baked Filo
Many filo dough recipes turn out better with a blind baked crust. Here are some good options:
- Spansakopita – Spinach pie with feta cheese filling
- Baklava – Layers of filo with nuts and honey
- Galatopita – Filo custard pie
- Tyropita – Cheese pie
- Bourekakia – Filo pastry cups or rolls stuffed with fillings
- Triangles – Filo wrapped around fillings then baked
The moisture in the fillings for these pies, pastries, and appetizers makes blind baking a must for best results.
Conclusion
Blind baking gives filo pastry a crispy, flaky jump start before fillings and final baking. While not required for every filo dough recipe, it’s a good idea anytime liquid fillings are used. Allow enough time for the filo to turn lightly golden without burning. With some practice, you’ll get perfectly crisped filo every time.
