Ingredients
For the Patties
- 2 medium zucchini, approximately 450–500 g total
- 1 cup rolled oats
- 2 large eggs
- ¼ cup finely grated Parmesan cheese
- 2 tablespoons finely chopped onion
- 1 garlic clove, finely minced
- 2 tablespoons fresh parsley, finely chopped
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon paprika
- ½ teaspoon dried Italian herbs
- 2 tablespoons all-purpose flour, optional
- 2–3 tablespoons olive oil for frying
Optional Additions
You can easily customize the recipe with ingredients such as:
- 2 tablespoons chopped green onions
- ½ teaspoon chili flakes
- 1 tablespoon fresh dill
- ¼ cup shredded cheddar cheese
- A small grated carrot
- A pinch of garlic powder
- A little lemon zest
- Freshly ground black pepper
Step 1: Prepare the Zucchini
Start by washing the zucchini thoroughly under cool running water. Dry it with a clean kitchen towel and trim off both ends.
There is no need to peel the zucchini. The green skin adds color, texture, and flavor to the finished patties.
Using the large side of a box grater, grate the zucchini into a large bowl. You want fairly fine shreds so the zucchini combines evenly with the oats and other ingredients.
If your zucchini is particularly large and contains large seeds, you can cut it lengthwise and remove some of the watery center before grating.
Step 2: Remove Excess Moisture
This is one of the most important steps in the entire recipe.
Zucchini naturally contains a large amount of water. If you leave too much moisture in the grated zucchini, the patties may become soft, difficult to shape, and less crispy.
Place the grated zucchini into a clean kitchen towel.
Gather the towel around the zucchini and squeeze firmly over the sink or a large bowl. Continue squeezing until a significant amount of liquid has been removed.
You can also use cheesecloth or a fine-mesh strainer. If using a strainer, press the zucchini firmly with the back of a spoon.
Do not worry about making the zucchini completely dry. The goal is simply to remove enough liquid so the mixture will hold together.
Step 3: Combine the Ingredients
Place the squeezed zucchini into a large mixing bowl.
Add the rolled oats, eggs, Parmesan cheese, chopped onion, minced garlic, parsley, paprika, Italian herbs, salt, and black pepper.
Using a wooden spoon or spatula, mix everything together thoroughly.
Make sure the eggs are evenly distributed throughout the mixture. The eggs will help bind the ingredients together as the patties cook.
The oats will begin absorbing some of the remaining moisture from the zucchini.
Step 4: Let the Mixture Rest
Once everything is combined, let the mixture rest for approximately 10–15 minutes.
This small step makes a noticeable difference.
During the resting time, the oats absorb moisture and become softer. This helps the mixture become easier to shape and helps prevent the patties from falling apart during cooking.
After resting, check the consistency.
The mixture should be moist but thick enough to hold its shape when pressed together.
If the mixture is too wet, add 1 tablespoon of flour and mix again. Add another tablespoon only if necessary.
Avoid adding too much flour because it can make the patties heavy.
Step 5: Shape the Patties
Line a plate or tray with parchment paper if desired.
Take a portion of the zucchini mixture using your hands or a spoon.
Gently press it together and form it into a round patty.
Flatten the patty slightly so it is about ½ inch thick.
Try to keep the patties approximately the same thickness. This helps them cook evenly.
Do not make them too thick because the outside can brown before the center is fully cooked.
Continue shaping until all of the mixture has been used.
Depending on the size, you should get approximately 8–10 patties.
Step 6: Heat the Skillet
Place a large nonstick skillet over medium heat.
Add 2–3 tablespoons of olive oil and allow it to heat for a minute or two.
You want the pan hot enough to create a gentle sizzle when the patties touch the surface.
Avoid using extremely high heat. If the pan is too hot, the outside can burn before the inside has had enough time to cook.
Medium heat gives the patties time to become golden and crisp while cooking the center properly.
Step 7: Cook the Patties
Carefully place the patties into the hot skillet.
Do not overcrowd the pan. Leave some space between each patty so you can easily flip them.
Cook the first side for approximately 3–5 minutes.
Watch the edges as they cook. When the underside becomes golden brown and the patty looks firm enough to flip, gently slide a spatula underneath.
Turn the patty over carefully.
Cook the second side for another 3–5 minutes, or until golden brown and crisp.
If the patties are browning too quickly, reduce the heat slightly.
If they are not developing any color after several minutes, increase the heat slightly.
Step 8: Drain the Cooked Patties
Once the patties are golden on both sides, transfer them to a plate lined with paper towels.
The paper towels will absorb some of the excess oil from the surface.
Allow the patties to rest for a couple of minutes before serving.
They will be crispest when served warm.
How to Get Extra-Crispy Patties
If crispiness is your main goal, focus on a few important details.
Squeeze the Zucchini Well
Excess water is the biggest enemy of crispy zucchini patties. Take your time when squeezing the grated zucchini.
Don’t Overcrowd the Pan
Too many patties in the skillet can lower the temperature and cause them to steam rather than crisp.
Cook in batches if necessary.
Use Medium Heat
Medium heat provides enough energy to brown the exterior without burning it.
Make Thin Patties
Slightly thinner patties develop more crispy surface area while still keeping a tender center.
Allow the Mixture to Rest
The oats need time to absorb moisture. Skipping the resting period can result in a wetter mixture.
Air Fryer Method
If you prefer using an air fryer, these patties work very well with that method.
Preheat the air fryer to 375°F (190°C).
Lightly brush or spray the patties with oil.
Place them in the air fryer basket in a single layer. Do not stack them.
Cook for approximately 10–14 minutes, turning them halfway through.
Continue cooking until the patties are golden and firm.
Because air fryer models vary, check the patties a little early the first time you make them.
Oven-Baked Method
You can also bake the patties in the oven.
Preheat the oven to 400°F (200°C).
Place the shaped patties on a parchment-lined baking sheet.
Lightly brush both sides with olive oil.
Bake for approximately 20–25 minutes, carefully turning halfway through.
The patties should become golden around the edges and firm in the center.
For extra browning, you can place them under the broiler for a short time at the end, watching them carefully.
Delicious Serving Ideas
These crispy zucchini oatmeal patties are incredibly versatile.
Serve them with a bowl of plain yogurt mixed with garlic, lemon juice, and fresh herbs.
For a fresh option, serve them alongside a tomato and cucumber salad.
They are also delicious with:
- Greek yogurt
- Sour cream
- Tzatziki
- Tomato salsa
- Avocado dip
- Garlic yogurt sauce
- Homemade tomato chutney
- Fresh green salad
For breakfast, serve the patties alongside scrambled eggs.
For lunch, pair them with salad and a dipping sauce.
For dinner, serve them as a vegetable side dish alongside grilled chicken, fish, or another main course.
They can also be served as a simple snack when you want something savory and crispy.
Storage
Allow leftover patties to cool completely before storing them.
Place them in an airtight container and refrigerate for up to 3 days.
For the best texture, reheat them in a skillet or air fryer rather than the microwave.
To reheat in a skillet, place the patties over medium heat and cook for a few minutes on each side until warm and crisp.
For an air fryer, heat them at approximately 350°F (175°C) until warmed through and crisp again.
Can You Freeze Them?
Yes, these patties can be frozen.
Allow the cooked patties to cool completely. Place them on a baking sheet in a single layer and freeze until firm.
Then transfer them to a freezer-safe container or bag.
Separating the patties with parchment paper can make it easier to remove individual portions later.
When ready to eat, reheat them directly from frozen in an oven, skillet, or air fryer until hot throughout.
Recipe Variations
One of the best things about this recipe is how easy it is to change.
Cheesy Zucchini Patties
Add extra shredded cheddar or mozzarella for a richer, cheesier version.
Spicy Zucchini Patties
Add chili flakes, cayenne pepper, or a little chopped fresh chili.
Herbed Zucchini Patties
Increase the fresh parsley and add dill, cilantro, or green onions.
Carrot-Zucchini Patties
Replace a small portion of the zucchini with finely grated carrot. Make sure to squeeze out excess moisture from the vegetables.
Garlic Herb Patties
Add an extra garlic clove along with fresh parsley and dried herbs.
Helpful Tips for Success
Use fresh zucchini: Fresh, firm zucchini gives the best texture.
Don’t skip squeezing: Removing excess moisture is essential for patties that hold together.
Rest the mixture: Give the oats time to absorb moisture before shaping.
Don’t make them too thick: Thin-to-medium patties cook more evenly.
Flip carefully: Wait until the first side is properly browned before turning.
Cook in batches: If your skillet is small, cooking fewer patties at once will help them become crisp.
Taste the mixture carefully: If desired, cook a tiny spoonful first to check the seasoning before shaping all the patties.
