Waffles Recipe with Garden Zucchini and Corn

These savory garden waffles combine grated zucchini, sweet corn, cheddar, and chives in a crisp-edged buttermilk batter. They make a satisfying breakfast or brunch, and squeezing excess moisture from the zucchini helps the waffles brown instead of turning soft.

Ingredients

2 cups (250 g) all-purpose flour
½ cup (75 g) fine yellow cornmeal
2 teaspoons (8 g) baking powder
½ teaspoon (3 g) fine salt
¼ teaspoon (0.5 g) freshly ground black pepper
1 tablespoon (12 g) granulated sugar
2 large eggs (about 100 g without shells)
1¾ cups (420 ml) buttermilk
⅓ cup (75 g) unsalted butter, melted and cooled slightly
1 medium zucchini, about 7 ounces (200 g) before squeezing; use about 1 cup (150 g) after draining
1 cup (150 g) fresh or thawed corn kernels
¾ cup (85 g) shredded sharp cheddar cheese
2 tablespoons (6 g) finely sliced fresh chives
Neutral oil or softened butter, as needed to grease the waffle iron

Instructions

Heat the waffle iron and prepare the zucchini. Set the waffle iron to medium-high or the setting recommended for crisp waffles. While it heats, trim and coarsely grate the zucchini. Pile it into a clean kitchen towel and squeeze firmly over the sink until it stops dripping. Measure about 1 cup (150 g) of squeezed zucchini. Removing water is important: zucchini releases liquid as it cooks, and too much can make the middle of a waffle damp even when the outside looks browned.
Combine the dry ingredients. In a large bowl, whisk the flour, cornmeal, baking powder, salt, pepper, and sugar until evenly mixed. Break up any compacted pockets of baking powder as you whisk. The cornmeal adds a gentle crunch and a lightly sweet corn flavor; it is not a substitute for all of the flour, because the flour provides most of the structure.
Whisk the wet ingredients. In a second bowl, whisk the eggs with the buttermilk. Slowly whisk in the melted butter. It should be warm rather than piping hot, so it blends smoothly without cooking the eggs. If the butter begins to form small firm flecks, the mixture may be very cold; let it stand briefly and whisk again.
Make a thick batter. Pour the wet mixture into the dry ingredients and fold with a spatula just until no large dry patches remain. A few small lumps are fine. Fold in the squeezed zucchini, corn, cheddar, and chives. The finished batter should be thick enough to mound on a spoon but still easy to scoop. Do not beat it smooth: overmixing develops gluten and can make waffles chewy rather than tender.
Grease the iron and portion the batter. Lightly brush or wipe the hot waffle grids with neutral oil or softened butter, following the appliance instructions. Add the amount of batter recommended for your machine, generally about ½ to ¾ cup (120 to 180 ml) for a standard Belgian-style waffle iron. Spread it gently toward the corners without pressing it into the grid. Smaller, thinner waffle irons may need less batter.
Cook until browned and crisp. Close the iron and cook for about 4 minutes per waffle, or until the steam has mostly subsided and the waffle is golden and releases without tearing. Exact timing varies by appliance, so use its indicator as a guide rather than opening the lid repeatedly. For egg safety, USDA FSIS gives 160°F (71°C) as the safe minimum internal temperature for egg dishes; check the center of a waffle from the first batch with an instant-read thermometer. If it has not reached that temperature, cook longer and check again.
Finish the remaining batter. Transfer cooked waffles to a wire rack in a single layer while you cook the rest, greasing the iron lightly again only if needed. A rack allows steam to escape; stacking hot waffles traps moisture and softens their crisp surfaces. The recipe makes about 8 standard waffles, though the yield depends on the size of the iron.
Serve while warm. Bring the waffles to the table as they are ready, or keep them on the rack in a low oven while finishing a batch. If using an oven, set it to 200°F (93°C), and do not cover the waffles. Serve with toppings at the table so each person can choose sweet, savory, or a little of both.

Tips

Squeeze the zucchini well. A salad spinner alone usually will not remove enough water from grated zucchini. Use a clean towel and wring it firmly; if the zucchini is especially large or watery, squeeze it in two batches. Weigh or measure it after squeezing so the batter stays balanced.
Use ingredients at a moderate temperature. Cold eggs and buttermilk can cause melted butter to firm into little pieces. Let them sit out while the iron heats, or warm the buttermilk gently until it is no longer refrigerator-cold. Do not use hot buttermilk, which could begin to cook the eggs.
Make a buttermilk substitute if needed. For this recipe, stir 1 tablespoon (15 ml) lemon juice or white vinegar into enough milk to make 1¾ cups (420 ml), then leave it for 5 minutes. It will be thinner and less tangy than cultured buttermilk, but it works in the batter. Plain yogurt thinned with milk is another option; add enough milk to make it pourable.
Keep the lid closed and use a rack. Opening the iron too soon can split a waffle before its crust sets. Once cooked, do not pile waffles on a plate if you want them crisp. If the first one is pale or soft, let the iron heat fully and cook the next waffle a little longer.

Serving Suggestions

For a savory plate, top each waffle with a fried or poached egg, sliced avocado, and a few extra chives. Cook eggs until the whites and yolks are firm, or follow safe handling guidance for the preparation you choose. A spoonful of plain Greek yogurt or sour cream, a handful of chopped tomatoes, and black pepper make a fresh, simple topping. For a more filling brunch, serve the waffles with a green salad dressed with lemon and olive oil, or alongside roasted tomatoes and sautéed mushrooms.

These waffles also work with a sweet-and-savory combination. Try a small drizzle of maple syrup with sharp cheddar, or serve them with apple slices and a little butter. Keep toppings moderate at first: very wet salsa, runny yogurt, or a large amount of syrup can soften the crisp surface. Put wetter toppings on just before eating, or serve them in a bowl on the side.

Variations

Use other garden vegetables: Replace the zucchini with squeezed grated yellow summer squash in the same amount. Finely chopped spinach can also work, but wilt it first, cool it, and press out excess water; adding it raw tends to make uneven pockets. You can swap up to ½ cup (75 g) of the corn for diced roasted red pepper, well-drained chopped scallions, or finely chopped cooked broccoli.

Change the cheese and herbs: Monterey Jack gives a milder, softer cheese flavor, while crumbled feta makes the waffles saltier and more tangy. If using feta, reduce the added salt slightly. Replace chives with 1 tablespoon (3 g) chopped fresh dill or parsley, or use 1 teaspoon (1 g) dried herbs when fresh ones are unavailable. Dried herbs taste more concentrated, so start with less.

Make them gluten-free: Use a cup-for-cup gluten-free all-purpose baking blend that includes a binder, such as xanthan gum, rather than replacing the flour with cornmeal alone. Different blends absorb liquid differently, so allow the batter to sit for 3 minutes after mixing and add 1 tablespoon (15 ml) buttermilk at a time if it becomes too stiff to scoop.

Make them without dairy: Use an unsweetened, unflavored plant-based milk with the lemon-juice treatment described in the tips, a neutral plant-based butter, and dairy-free shredded cheese. The flavor and browning can differ slightly from the buttermilk-and-cheddar version. Check the waffle iron instructions for an appropriate nonstick grease.

Storage and Reheating

Let leftover waffles cool on a rack, then refrigerate them in a covered container within 2 hours of cooking. They keep for 3 to 4 days in the refrigerator. For longer storage, freeze cooled waffles in a single layer until firm, then transfer them to a freezer-safe bag or container with parchment between layers; use within about 2 months for best texture. Label the container with the date so older waffles are easy to use first.

Reheat refrigerated or frozen waffles in a toaster, toaster oven, or oven until hot throughout and crisp at the edges. A toaster works well for standard-size waffles; thicker waffles may need a lower setting and a second cycle so the outside does not overbrown before the middle warms. In an oven, arrange them in a single layer at 350°F (175°C) for about 8 to 10 minutes from the refrigerator, or 12 to 15 minutes from frozen, turning once if needed. USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center of a thick waffle with a food thermometer. Avoid microwaving if crispness matters, since it tends to soften the crust.

Frequently Asked Questions

Can I make the batter ahead?
For the best rise and texture, mix the wet and dry ingredients shortly before cooking. Baking powder begins reacting once it is mixed with liquid, so a long wait can leave the waffles less airy. You can grate and squeeze the zucchini, shred the cheese, and measure the dry ingredients a day ahead; refrigerate the prepared zucchini and cheese separately in covered containers.

Why are my waffles soggy in the middle?
The most common causes are zucchini that was not squeezed enough, an iron that was not fully hot, or waffles removed before their steam had mostly stopped. A heavy pile of toppings can also make a crisp waffle soft. Squeeze the measured zucchini firmly, preheat the iron completely, and cook until the waffle is browned and releases easily.

Can I use frozen corn?
Yes. Thaw it first and pat it dry so ice crystals do not add water to the batter. Canned corn also works if it is drained well and blotted dry. Fresh corn cut from the cob gives a slightly firmer bite, but it does not need to be cooked before mixing into the batter.

Can I cook these in a regular waffle iron?
Yes. The recipe works in a standard or Belgian-style iron, though each machine makes waffles of a different size and thickness. Start with the amount recommended in the appliance manual and adjust after the first waffle. A deeper iron may need slightly longer cooking, while a shallow iron may brown the batter faster.

Can I make the waffles without cornmeal?
Yes. Replace the ½ cup (75 g) cornmeal with ½ cup (62 g) additional all-purpose flour. The waffles will be a little softer and will lose the cornmeal’s lightly crisp, toasted texture, but the recipe should still cook properly. Keep the remaining ingredients and amounts unchanged.
