Should you backyard, you’re aware of the issue. One week your zucchini plant is producing a number of well mannered, normal-sized squash. Two weeks later you’re hiding a club-shaped monster behind the tomato cages, hoping no one asks whose it’s. Each gardener finally ends up with a minimum of one zucchini too huge and too seedy to slice, sauté, or stuff into one other loaf of bread.
That overgrown zucchini isn’t a loss. It’s the absolute best candidate for zucchini flour, generally known as “Amish flour”, a shelf-stable, mild-tasting flour you make by drying and grinding zucchini. About 5 kilos of zucchini—roughly two or three of these outsized backyard monsters—dries and grinds right down to about one cup of flour. That’s a complete cup of pantry-stable flour from squash that may in any other case go comfortable within the crisper drawer or straight to the compost bin.
Right here’s the right way to make it, the right way to retailer it so it lasts, and the right way to use it after getting it.
What Is Zucchini Flour, and Why Is It Known as Amish Flour?
Zucchini flour is dried, floor zucchini. That’s it. There’s no further processing, no components, nothing you’ll be able to’t do in your personal kitchen with a dehydrator or oven and a blender. As soon as floor positive, it seems to be like a pale, yellow, or green-flecked flour (relying on the zucchini you utilize), and carries a really gentle, faintly candy taste that principally disappears as soon as it’s baked into one thing else.
You’ll see it known as “Amish flour” or “Mennonite flour” simply as usually as zucchini flour. Dwelling cooking blogs and homesteading websites broadly describe it as a standard Amish and Mennonite kitchen staple, and lots of hint its wider recognition to the wheat rationing of the Nineteen Forties, when dwelling cooks stretched their flour provide with regardless of the backyard offered.5 Sadly, there isn’t a single interval cookbook, ration-era pamphlet, or Amish neighborhood document that really confirms both declare. Deal with it as common kitchen folklore that’s enjoyable to say, not settled meals historical past.
What is nicely established is the sensible case for making it. Zucchini is roughly 93 % water recent off the vine.1 Drying it down concentrates the fiber, the minerals, and the modest quantity of protein right into a fraction of the unique quantity. You find yourself with a flour that’s naturally gluten free, low carb in comparison with wheat flour, excessive in fiber, and comprises nutritional vitamins A, C, and K1, in addition to potassium and magnesium. Plus, it’s a genuinely helpful method to sneak greens into baked items for choosy eaters.
Selecting and Prepping Your Zucchini
That is the one undertaking the place the zucchini you don’t need is strictly the zucchini you want. Smaller, younger zucchini don’t require peeling or seeding, for the reason that pores and skin and seeds are nonetheless tender.6 However these big, baseball-bat-sized zucchini that acquired away from you throughout a busy week? They’re excellent for flour. Their harder pores and skin and bigger, more durable seeds are an issue for consuming recent, however when you’re drying and grinding the entire thing anyway, dimension stops being a draw back.
For the most important zucchini, I do advocate peeling and eradicating the seed core first, until you need to sift the flour after grinding. The pores and skin can toughen the feel of your completed flour, and enormous seeds decelerate each drying and grinding. Smaller and medium zucchini can go into the dehydrator pores and skin, seeds, and all.
No matter dimension you’re working with, wash and dry the zucchini nicely earlier than you begin. Trim the stem and blossom ends, and reduce away any comfortable or blemished spots.
Step 1: Shred or Slice Your Zucchini
You have got two choices right here, and each work nice.
Shredding is the sooner route. Run your zucchini via the shredding disc of a meals processor, or use a field grater in the event you’re working in smaller batches. Shredded zucchini dries sooner than sliced as a result of it has extra floor space uncovered to air, and it crumbles simply as soon as dry, which makes grinding faster later.
Slicing is the higher possibility in the event you don’t have a shredding attachment otherwise you’d moderately work with a knife or mandolin. Lower your zucchini into skinny, even slices, about an eighth to 1 / 4 inch thick.1 Thinner slices dry sooner and extra evenly than thick ones, so take care to maintain your cuts constant.
Should you shred your zucchini, let the shreds drain in a colander for fifteen to twenty minutes first, gently urgent any water out of them with the again of a spoon or clear cotton fabric. Zucchini holds lots of water, and giving a few of it a head begin out of the vegetable means much less time within the dehydrator.
Step 2: Dry It in a Dehydrator or Oven
Dehydrator methodology: Unfold your shredded or sliced zucchini in a single layer with somewhat house between items so air can transfer freely round them, and dehydrate at 130–135°F for 12 to 18 hours.1,2 Rotate the trays midway via the method. For flour, slower drying tends to protect extra of the gentle taste and colour, so you can go as little as 115°F, however it’ll take for much longer to dry completely.
Oven methodology: No dehydrator, no downside. Set your oven to its lowest attainable temperature, ideally round 150°F, and prop the door open a number of inches so moisture can escape as an alternative of turning your oven right into a steam field. Unfold the zucchini on parchment-lined baking sheets and verify each hour or so. Relying in your oven and the way skinny you chop or shredded the zucchini, this sometimes takes wherever from two to eight hours, so hold your eye on issues.
Nevertheless you dry it, use the identical check to know you’re finished: The zucchini must be brittle sufficient to crack or snap once you bend it, with no give and no dampness wherever.1 If it bends as an alternative of breaking, it wants extra time. This isn’t a step to hurry. Underdried zucchini is how you find yourself with mildew in your storage container every week later.1
Step 3: Grind It Into Flour
As soon as your zucchini is totally dry and cooled, it’s able to grind. A high-speed blender, spice grinder, meals processor, or a grain mill will all get you there. Fill your grinder about two-thirds full, no extra, and mix or course of till you will have a positive, even powder. I exploit my meals processor to interrupt down the dried zucchini shreds into coarse meal, then run that via my small spice grinder to get the best powder. You would possibly have to sift out a number of the bigger particles or bits of seed, which you’ll regrind or compost.
After grinding, let the container sit for a couple of minutes with the lid nonetheless on earlier than you open it. Zucchini flour is okay and light-weight—nearer to powdered sugar than cornmeal—and opening the lid too quickly sends a cloud of it straight into your kitchen air. Should you’ve ever opened a meals processor too early after grinding pepper or powdered sugar, you realize precisely what I imply.
Should you left the skins on, count on the grinding to take somewhat longer to achieve a positive, even texture, and count on a flour with a noticeable inexperienced tint. That’s utterly regular and has no impact on taste or security. You may at all times sift on the finish to get any bigger particles out, after which regrind or compost them.
Retailer Zucchini Flour, and How Lengthy It Lasts
Zucchini flour is hygroscopic, which means it actively pulls moisture out of the air round it.7 That makes correct storage extra essential than it will be for normal wheat flour.
Earlier than you decide to long-term storage, give your flour a conditioning verify. Pack it loosely into a transparent, hermetic container and verify it day by day for a couple of week, shaking gently to redistribute it and looking forward to any signal of condensation on the within of the jar. Should you spot moisture, it means some items weren’t totally dry earlier than grinding. Unfold the flour again out and dry it additional earlier than storing. Should you see any mildew, discard that batch. It isn’t well worth the threat.
As soon as your flour passes the conditioning verify, retailer it in a clear, hermetic container in a cool, darkish, dry spot like a pantry cupboard. Add a food-safe desiccant packet or oxygen absorber, particularly in the event you dwell someplace humid, otherwise you’ll be opening the container usually.5
For shelf life, most extension courses on dwelling meals preservation generally train a one-year shelf life as a common guideline for dehydrated meals at room temperature.1,2 Penn State and West Virginia College Extension state that commercially dried zucchini has a shelf lifetime of as much as six months.3 Since there isn’t any lab-tested shelf life knowledge for home-ground zucchini flour, deal with six months to a yr as an inexpensive vary for storage security. If you’d like your flour to final nicely previous that window, the freezer (or freeze drying) is your finest wager. Frozen in an hermetic, moisture-proof container, it’ll maintain its high quality far longer than in a pantry.
Use Zucchini Flour
Zucchini flour isn’t a one-to-one alternative for wheat flour in most recipes. It has no gluten, so it gained’t present construction the way in which wheat flour does, and it behaves extra like a moisture-absorbing add-in than a real structural flour.
As a partial flour substitute. You may substitute as much as a 3rd of the flour in a recipe with zucchini flour, protecting the remaining as your common all-purpose or entire wheat flour. Some bakers push that ratio as excessive as half, significantly in already-moist recipes like muffins, brownies, and desserts. Begin by changing only a quarter (or 1 to three ratio) in the event you’re testing a brand new recipe, and alter from there as soon as you know the way your particular batch of flour behaves.
As a coconut flour swap. Should you already bake gluten free, zucchini flour can typically substitute coconut flour one to 1 in recipes. This can be a significantly helpful swap in the event you’ve ever discovered coconut flour recipes to have a faint aftertaste you’d moderately keep away from. I discover it makes for a greater texture in my baked items than coconut flour, too.
As a thickener. A spoonful or two whisked into soups, stews, gravies, or sauces provides lots of physique with out a lot taste of its personal.
As a breading. Zucchini flour makes a strong low-carb, crispy coating for pan-fried or baked rooster, fish, or greens, both by itself or blended along with your normal breading. We’ve been having fun with all of it summer season on our fresh-caught lake trout!
In smoothies and shakes. Add a tablespoon of zucchini flour to your smoothies or protein shakes for an additional increase of fiber and vitamins.
Recipes That Use Zucchini Flour
After you have a jar of zucchini flour on the shelf, listed here are a number of recipes that put it to work.
Frequent Errors to Keep away from
Underdrying. In case your zucchini bends as an alternative of snapping, it isn’t finished. Give it extra time earlier than you grind it; it might’t be too dry.
Skipping the conditioning verify. It’s tempting to jar up your flour the second it’s floor and name it finished. The week-long verify catches hidden moisture pockets earlier than they flip into mildew in a sealed container.
Grinding it too coarse. A gritty, inconsistently floor flour gained’t incorporate nicely into batters and may depart a barely sandy texture in your completed baked items. Take the additional minute to sift and grind to get a positive, even powder.
Treating it like a one-to-one wheat flour swap. Zucchini flour has no gluten. Recipes that lean on it too closely with out adjusting for construction have a tendency to return out dense or crumbly. Begin with the partial-substitution ratios above moderately than swapping it in wholesale.
Regularly Requested Questions
Can I exploit different summer season squash as an alternative of zucchini?

Can I can zucchini as an alternative of drying it?
No, canning zucchini is a nasty concept. Plain zucchini is a low-acid meals, and the water bathtub methodology isn’t secure for it, whereas stress canning turns it into mush.4 Freezing, pickling or dehydrating are the secure, examined dwelling preservation strategies for zucchini by itself.
