Zucchini, the versatile summer squash, has long been a favorite in kitchens around the world, but sometimes we wonder what to do with these great growers. We grille, bake, sauté them, make bread with them, etc.  It’s mild flavor and tender texture make it a culinary chameleon. But have you ever considered zucchini in the form of flour? It’s wondrous! Zucchini flour is a nutritious, gluten-free alternative that can enhance your cooking and baking repertoire. Here’s a guide on how to create zucchini flour and explore its myriad uses.  And I’ve even included a couple of basic recipes that I use to incorporate the zucchini flour. Because I’m a full- service gal like that. Ha!  And yes, you can make these recipes from shelf-stable ingredients.

How to Create Zucchini Flour

Ingredients:

• Fresh zucchini (as many as you like)

Equipment:

• Dehydrator or oven (and yes, this works in your solar oven)
• Food processor or high-speed blender (here’s a link to a hand-cranked food processor that I love. Great for use if there’s no electricity)
• Fine mesh sieve or flour sifter

Steps:

1. Preparation:
   • Wash the zucchini thoroughly to remove any dirt or residue.
   • Slice the zucchini into thin rounds. The thinner the slices, the quicker they will dry.

1. Drying:
   • Using a Dehydrator: Arrange the zucchini slices on the dehydrator trays in a single layer. Set the dehydrator to 135°F (57°C) and dry for 8-12

     hours, or until the zucchini is completely dry and brittle.

   • Using an Oven: Preheat your oven to its lowest setting, usually around 150-170°F (65-75°C). Place the zucchini slices on a baking sheet lined with parchment paper. Dry in the oven for 6-10 hours, checking periodically to ensure they don’t burn. Flip the slices halfway through for even drying.

1. Grinding:
   • Once the zucchini slices are completely dry, let them cool to room temperature.
   • Transfer the dried zucchini to a food processor or high-speed blender. Grind until you achieve a fine, flour-like consistency.

1. Sifting:
   • Pass the ground zucchini through a fine mesh sieve or flour sifter to remove any larger pieces. Re-grind any pieces that don’t pass through the sieve.

1. Storage:
   • Store your zucchini flour in an airtight container in a cool, dry place. Properly stored, it can last for several months. If you seal it up with a Foodsaver each time you get into it, you’ll get a couple of years out of it.

Zucchini flour is a versatile ingredient that can be used in a variety of recipes. Its mild flavor makes it an excellent addition to both savory and sweet dishes. Here are some popular uses:

1. Baking:
   • Bread and Muffins: Substitute zucchini flour for up to 50% of the all-purpose or whole wheat flour in your favorite bread and muffin recipes. This adds a nutritional boost and a moist texture.
   • Pancakes and Waffles: Use zucchini flour to make gluten-free pancakes and waffles. Combine it with other gluten-free flours like almond or coconut flour for best results.
   • Cookies and Brownies: Add zucchini flour to cookie and brownie batters to enhance moisture and nutrition without altering the flavor significantly. (again, I use it half and half with the regular flour)

1. Thickening Agent:
   • Use zucchini flour as a thickening agent for soups, stews, and sauces. It’s WONDERFUL as a thickening agent! It provides a subtle flavor while adding body and nutrition to your dishes.

1. Coating and Breading:
   • Use zucchini flour as a coating for fried or baked foods. It works well for breading chicken, fish, or vegetables, giving them a crispy texture.

1. Smoothies and Shakes:
   • Add a tablespoon of zucchini flour to your smoothies or protein shakes for an extra boost of fiber and nutrients.

1. Pasta and Pizza Dough:
   • Incorporate zucchini flour into homemade pasta or pizza dough for a unique twist. It adds a mild flavor and enhances the nutritional profile of your dishes.  This way you can have gluten-free pizza and pasta. And to be frank, I like making zucchini pasta, period.  It tastes divine.
