Baked Sourdough Tortilla Corn Chips Recipe (Active or Discard Starter)

Last Updated on August 2, 2023

Are you ready to add one more awesome homemade sourdough recipe to your repertoire? Good. Because these crispy, flaky sourdough corn chips are fit to be a repeat guest at your table! They’re incredibly easy to make, with a flexible recipe to accommodate your schedule. As with all fermented sourdough goodies, homemade sourdough corn chips are a healthier alternative to processed store-bought snacks. Made with either fresh (active) or discarded sourdough starter, this is also a great way to use up extra starter.

Imagine if tortilla chips, pita chips, and crackers got together to make a delicious crunchy baby. This baked sourdough corn chips recipe is exactly that!

If you’ve made our infamous herbed whole wheat sourdough crackers before, this is going to feel extra easy and familiar! The process of making baked sourdough corn chips is essentially the same, but with even fewer steps and ingredients. As much as I love those crackers, the approaching summer season had me craving something a little different. Sourdough corn chips are the perfect dipping companion for salsa, guacamole, bean dip, hummus, or even alongside a dinner of soup, lentils, or chili!

You will need an established sourdough starter to make baked sourdough corn chips. If you don’t have a starter yet, don’t fret! Check out this article to learn how to make your own starter from scratch at home. Or, for even less fuss, pick up an organic sourdough starter from our shop. Once you have an established starter, you can enjoy baking rustic sourdough bread, focaccia, pizza crust, crackers, and more!

INGREDIENTS

• 1 cup cornmeal OR masa corn flour (traditionally used for making tortillas). If using cornmeal, I suggest using a fine to medium grind for best binding. We like to use this organic medium-coarse cornmeal, which gives the chips a nice bit of grit. Masa flour is made with corn that has been soaked in limewater, so it provides more of a classic tortilla flavor.
• 1 cup sourdough starter. For this recipe, you can use sourdough starter discard or fresh active (recently fed) starter. We prefer to use active starter, mostly because our starter often sits in the fridge for up to two weeks before being discarded and fed again. In that state, it is very acidic and sour. A hungry, unfed starter will result in a more tangy chip flavor. Using starter at peak activity (as you would in a bread recipe) will result in a more light and flaky chip.
• ½ teaspoon sea salt
• ¼ cup (4 tablespoons) of coconut oil, olive oil, or butter (softened)
• Olive oil, for brushing
• Coarse sea salt, for sprinkling on top
• Optional: garlic powder, onion powder, lemon powder, or other seasonings of choice. Finely grated cheese is always welcome at this fiesta too!

Quantity

This recipe makes 2 full baking sheets or approximately 6 to 7 dozen sourdough tortilla corn chips (depending on the size and shape you cut them). The full recipe is perfect for a family, party, gathering, or a few days of snacking. With just the two of us here, we sometimes make a half-batch only. They’re so addicting, we’d devour them all in a day or two otherwise! They do stay crunchy for several days with proper storage.

DIRECTIONS

1) Mix dough

In a large mixing bowl, combine all of the ingredients listed above: 1 cup cornmeal or masa flour, 1 cup sourdough starter, 1/2 teaspoon of salt, and 1/4 cup oil or butter of choice. If you opt to use coconut oil or butter, lightly heat it as needed to make it soft and easy to work with.

Baked sourdough corn chips are awesome as-is, but feel free to spice them up if you’d like. Sometimes we add a sprinkle (about 1/4 tsp) of homegrown garlic powder or onion powder, or even a little dash of lemon and chili powder for a fun twist! Everything-but-the-bagel seasoning and/or a handful of grated cheese is also amazing. Soon, I want to experiment with adding a handful of flax seeds to the mix. You can add extra seasonings early with the dough, or lightly sprinkled over the top later – once the raw chips are rolled out.

Thoroughly mix the dough until it is uniform. I usually start mixing with a fork or spoon, but then finish mixing with my hands. The oil or butter prevents it from being too sticky. The texture should be similar to cookie dough, but more rough from the cornmeal.

2) Split, Squish & Chill

Divide the large dough ball into two smaller balls that are roughly the same size. (That is, if you made a full batch; form just one ball for a half-batch.) Using your hands, form each ball into a flattened rectangle. We have been vegetarian for a loooong time, but this step definitely reminds me of forming hamburger patties, if that helps… Mine generally end up a little larger than my flattened hand, and about half an inch thick. Repeat for the second ball.

Wrap each rectangle of dough in parchment paper, plastic wrap, or better yet, reusable beeswax wraps! The purpose is to prevent the dough from drying out. We set each one on a small plate, though you could put them together on one larger plate – or skip the plate all together and stick them right in the fridge.

Finally, refrigerate your flattened dough for at least 30 minutes, up to several hours. This is where the recipe is nice and flexible for your schedule! The main benefit of an extended time in the fridge is added time for the sourdough starter to ferment the cornmeal, which will make it slightly healthier and easy to digest. We typically let it sit for at least an hour.

3) Roll Out

Preheat the oven to 350°F.

Once they’ve had time to chill, remove the sourdough corn chip dough from the fridge. Cut a piece of parchment paper to the size of the baking sheet, or use a handy silicone baking sheet liner. Lightly dust the parchment paper/liner with a small amount of cornmeal. Carefully unwrap one chunk of flattened dough, place it in the center of the parchment paper, and then lightly dust the top of the dough with cornmeal as well. I like to do this on a large cutting board, which makes it very easy to transfer the cut raw chips onto the baking sheets.

Using a rolling pin, roll out the dough until it is nice and thin. The goal is about 1/16th of an inch thick or less. The edges may get a little ragged; that’s okay. Just work it back and forth and side to side to spread the dough as evenly as possible, while still maintaining a relatively rectangular shape. The thinner you roll them, the more crisp your sourdough corn chips will be!

4) Oil, Salt & Cut

Once the dough is rolled out, lightly brush the surface with a thin even coating of olive oil. Make sure to get the edges! Then sprinkle some coarse sea salt over it as well. Here is where you could opt to add a little extra seasonings of choice, if you didn’t already when mixing the dough. Or, keep them simply salted!

Next, cut the dough into rows of either squares, strips, or triangle chips. The use of a rolling pizza cutter works very well for this. Anything in the ballpark of 1 to 2 inches is good. Squares are definitely the easiest to cut, but triangles are fun too! We are making sourdough corn chips after all. You can also use a pastry/pasta cutter to cut them and create fun wavy edges.

Repeat Steps 3 and 4 for the second piece of dough.

5) Bake

Slide the parchment paper with the cut chips onto a baking sheet. Each batch will need its own sheet. We bake two trays at one time, but if you only have one baking sheet to work with, have them take turns.

Bake on 350°F for approximately 25 minutes*, until the chips turn lightly golden brown and crisp. Rotate and switch the cookie sheets halfway through baking. It is common for the outermost edges to get “done” more quickly than the inner chips. Personally, I find it worthwhile to ever-so-slightly overcook the ragged edges in order to get the ideal crunch in the rest of the batch. The more crisp your baked sourdough corn chips are out of the oven, the longer the crunch lasts in storage.

When they are done baking, immediately transfer your finished sourdough corn chips off of the baking sheet (and parchment paper) and on to a cooling rack.

*Note: Baking times will slightly vary by individual oven, how thin you roll out your chips, and also depending on if you bake one or two trays at a time.

6) Enjoy

The moment we’ve all been waiting for! You’ve probably already sampled a few by now… I always snack on those irregular outer pieces right away. They’re too irresistible, and “not pretty” enough to make it to the plate anyways, right?! Right. Of course.  

Now, dig in! These sourdough corn chips are best freshly-baked. Enjoy them any way you’d like – with your favorite dips, or plain on their own. Your friends and family are going to be SO impressed that you made homemade chips!

After they are fully cool, store the chips in an air-tight container to maintain maximum freshness and crunch. We like to use a glass food storage container with snap-on sealing lid. They may get a tad stale after 4 or 5 days in storage, but ours don’t usually last that long anyway!

Ta da! You just made homemade baked sourdough tortilla corn chips.

Notes

1. For this recipe, you can use sourdough starter discard or fresh active (recently fed) starter. We prefer to use active starter, mostly because our starter often sits in the fridge for up to two weeks before being discarded and fed again. In that state, it is very acidic and sour. A hungry, unfed starter will result in a more tangy chip flavor. Using starter at peak activity (as you would in a bread recipe) will result in a more light and flaky chip.
2. Baking times will slightly vary by individual oven, how thin you roll out your chips, and also depending on if you bake one or two trays at a time.
