zucchini substitute
in meatloaf.
Zucchini contributes mild flavor and moisture to Meatloaf, shaping the binding and moisture. At ~95% water by weight, shredded zucchini must be salted and squeezed before adding; a substitute should be pre-treated the same way to control the amount of free water introduced into the meat mixture, or the loaf will steam instead of bake and won't slice cleanly.

adjustment for this dish
Cucumber carries more free water than zucchini (~96% vs 95%) and less structural pectin, so salt-drain for 20 minutes, not 10, and squeeze until you lose 1/2 cup of liquid per cup grated. Cut breadcrumbs by 1 tbsp since cucumber won't bind as effectively into the loaf shape.

Mushrooms

Works in sauteed and baked dishes
10.0
adjustment for this dish
Mushrooms bring glutamates that deepen beef flavor and hold their dice shape through a 55-minute bake better than zucchini. Use 1 cup finely diced cremini, saute dry until they squeak (about 6 min), and mix in cooled. Skip the milk entirely since mushrooms add seasoned moisture on their own.

Bell Pepper

Works in stir-fries and grilled dishes

adjustment for this dish
Bell pepper has firmer walls than zucchini and won't disappear into the bind; mince to 2mm dice, sweat in 1 tsp oil 4 minutes to pull the raw edge, then cool and mix. Season with an extra 1/4 tsp salt per pound. Pepper sweetness otherwise flattens the crust flavor.

Broccoli
5.01 cup : 1 cup
Works roasted or in casseroles
5.0
adjustment for this dish
Broccoli stems (not florets) mimic zucchini's bulk best; peel, grate on large holes, squeeze, and use 1:1 by volume. Add 1 tsp Worcestershire to rebuild the savory depth. Broccoli brings sulfur and vegetal notes that can push a baked loaf toward cabbage unless the glaze balances it.
05
Chayote
5.01 cup : 1 cup
Mild squash, closest texture match
5.0
adjustment for this dish
Chayote has denser flesh than zucchini so it holds dice shape through the full 55-minute bake without weeping. Peel, dice to 1/4 inch, and use raw. No salt-draining needed. Add 1 tbsp milk to the mix since chayote contributes less moisture to the bind than zucchini does.

technique for meatloaf
technique
Zucchini replaces about 30% of the breadcrumbs in a standard meatloaf mix without making the loaf fall apart, provided you salt the shreds for 10 minutes and squeeze out the brine. A 1-cup portion of unsalted grated zucchini dumps roughly 3 tablespoons of water into the mix, which is enough to turn a 9x5 loaf pan into a soggy trough if you also use the full egg and milk the recipe calls for.
Cut the milk to 2 tablespoons when zucchini goes in. Bind the mix by working it just until the egg streaks disappear, then shape by hand on a sheet pan (a free-form loaf browns on five sides, not three like a pan bake).
Bake at 375F for 55 minutes, brush the glaze at 40 minutes so the sugars set a crust without burning, and rest 10 minutes before you slice or the juices run. 5 tsp kosher salt per pound since zucchini dilutes the seasoning you taste in the raw mix.
pitfalls to avoid
watch out
Salt the grated zucchini 10 minutes and squeeze hard before mixing. Skipping this step dumps 3 tbsp of water into the loaf pan and gives you a soggy bottom and a slumped shape.
watch out
Reduce the milk in the mix to 2 tbsp when adding a cup of zucchini; the vegetable binds moisture well on its own and excess liquid breaks the bind with egg and breadcrumbs.
watch out
Don't overmix the meat once zucchini is in. Work it 30 seconds max or the proteins tighten into a rubbery slice instead of a tender crumb.
watch out
Avoid brushing glaze before 40 minutes of baking; sugar scorches on the crust before the interior sets if you glaze at the start.
watch out
Rest the loaf 10 minutes before you slice, or the moisture zucchini released during bake pours out of every cut and leaves the meat dry.
