Sourdough Discard Flatbread Recipe: The Greek Inspired Dinner We Keep Making

Today I am sharing my easy sourdough discard flatbread recipe made with simple ingredients and served with a flavorful Greek-style venison dinner!
Hello friends! In last week’s video, I shared my sourdough discard flatbread recipe with a venison gyro-style filling. Many of you requested a recipe post, so today I’m sharing an in-depth version for you to follow and make your own Greek-style dinner.

I’ve been using this recipe for a long time, and we love it. Or I should say, my husband loves it and so do the kids. I actually can’t have it because it has gluten, but whenever we have Greek food, I typically just make myself a salad and I’m pretty content with that. Every once in a while, I’ll try a gluten-free flatbread recipe, but for today’s post, I’m sharing my usual sourdough discard flatbread recipe.

Sourdough Flatbread
We’re going to start with:
- 1/2 cup milk
- 1 cup sourdough discard

I’ve got lots here! Whenever I need to use up some discard (I don’t keep a separate jar for it), I just use it in a recipe when my starter goes flat. This calls for a whole cup, so it’s a great way to use it up.

To that, we’re going to add:
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon salt
- 1 tablespoon olive oil
Super simple to throw together, and then this will be all ready to go. Of course, you could do this the night before if you wanted to.
Venison Meat Mixture
Next, we’re going to get started on our meat mixture. First, just get your meat into a bowl. Like I said before, I’m using venison for this recipe because we have so much of it. The recipe technically calls for a pound of lamb and a pound of beef, but we’re just using venison, so hopefully it’ll turn out okay.

To the meat, add:
- 1/4 cup gluten-free breadcrumbs (I didn’t actually have gluten-free breadcrumbs, so I used gluten-free croutons and crushed those up)
- 5 cloves garlic
- 1 whole onion
- 1 tablespoon dried oregano
- 2 teaspoons cumin
- 2 teaspoons salt
- 1 teaspoon pepper
We’re going to get this all mixed up. I’m excited to try this! We love the chicken thigh version, so hopefully this one will be just as good.

Note: I also added some olive oil to the meat mixture and coated the pan in olive oil to add more fat since venison is a leaner meat.
Toppings
We have all of our toppings ready for tonight:
- Pickled beets
- Pickled onions (I always keep these in the fridge; we love them so much)
- Chopped cucumber
- Cherry tomatoes
- Olives (I think I’m the only one who likes those!)
- Homemade tzatziki sauce
- Feta cheese
I typically like to chop up some romaine lettuce too, but we’re all out at the moment, so we’re just going to do without.
Cooking & Assembly
I put the venison in for about 35 minutes, and it looked done to me, so I’m glad I pulled it before the 50-minute mark. Maybe if I had used lamb or beef, it would have taken longer.

My boys love helping with the flatbread, and they look delicious. We’re just going to put everything together now. I tried a little bit of the meat, and wow, it is super flavorful!
