Grate zucchini and carrots. Place the zucchini in a towel and squeeze out as much water as you can.
Mix zucchini, carrots, onion, garlic, almond flour, Parmesan, eggs, salt, and pepper in a large bowl until combined.
Shape the mixture into small patties, about the size of your palm.
Heat olive oil in a skillet over medium heat.
Cook the patties for 3 to 4 minutes per side until golden brown and firm in the center.
Place cooked patties on a plate lined with paper towels to absorb extra oil.
Serve warm with salad, dipping sauce, or in a bun if you like.
