This Vegan Shredded Zucchini Casserole is a cozy, savory side dish that turns simple zucchini into something wonderfully creamy, tender, and satisfying. Freshly shredded zucchini is combined with aromatic onion, garlic, herbs, and a creamy plant-based mixture, then baked until bubbling and lightly golden on top. It’s an easy way to enjoy plenty of vegetables in a comforting casserole that works beautifully for family dinners, potlucks, and holiday tables.
Can This Vegan Shredded Zucchini Casserole Support Weight Loss Goals?
Yes, it can fit into a balanced weight-management eating pattern because zucchini is naturally low in calories while providing volume and some fiber. The creamy ingredients and breadcrumbs contribute more calories, so portion sizes and ingredient choices still matter. Using a lighter plant-based cream and plenty of zucchini can keep the casserole relatively balanced. For a more filling meal, pair it with a protein-rich vegan main dish such as tofu, tempeh, lentils, or beans.
Does Vegan Shredded Zucchini Casserole Fit a High-Protein Lifestyle?
This casserole is vegetable-focused rather than naturally highprotein, but it can easily become part of a high-protein vegan meal. Nutritional yeast and plant-based milk contribute some protein, while a soy-based vegan cream cheese can provide more. The net carbs remain moderate because zucchini contains relatively few carbohydrates, although breadcrumbs add additional carbs. For a low-carb version, replace the breadcrumbs with crushed almonds or a low-carb seed topping.

📝 Ingredients
Zucchini Filling
- 6 medium zucchini, approximately 2½ lb (1.1 kg)
- 1 tablespoon olive oil
- 1 medium yellow onion, finely diced
- 3 cloves garlic, minced
- 8 oz (226 g) vegan cream cheese, softened
- ½ cup (120 ml) unsweetened plant-based milk
- ¼ cup (15 g) nutritional yeast
- 1 teaspoon dried Italian seasoning
- ½ teaspoon onion powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 2 tablespoons fresh parsley, chopped
Crispy Topping
- ¾ cup (45 g) panko breadcrumbs
- 1 tablespoon olive oil
- 1 tablespoon nutritional yeast
- ½ teaspoon garlic powder
- ¼ teaspoon smoked paprika
Ingredient notes: Use plain, unsweetened plant-based milk. A soy-based vegan cream cheese generally provides more protein than some nut- or coconut-based alternatives.
Directions
- Preheat the oven: Heat the oven to 375°F (190°C).
- Prepare the zucchini: Wash and trim the zucchini, then shred it using the large holes of a box grater.
- Remove excess moisture: Place the shredded zucchini in a clean kitchen towel and squeeze firmly until a significant amount of liquid has been removed. This step is important for preventing a watery casserole.
- Prepare the onion: Heat olive oil in a large skillet over medium heat.
- Sauté the onion: Add diced onion and cook for 4–5 minutes, stirring occasionally, until softened.
- Add garlic: Stir in minced garlic and cook for 30–45 seconds, until fragrant.
- Make the creamy mixture: Reduce heat to low. Add vegan cream cheese and plant-based milk.
- Stir until smooth: Cook gently for 2–3 minutes, stirring until the cream cheese melts into a smooth sauce.
- Season: Stir in nutritional yeast, Italian seasoning, onion powder, salt, and black pepper.
- Add zucchini: Remove the skillet from the heat and fold in the squeezed shredded zucchini and fresh parsley.
- Check texture: The mixture should look creamy but not soupy. If it appears excessively wet, squeeze the zucchini again before continuing.
- Transfer to dish: Lightly grease a 9×13-inch baking dish and spread the zucchini mixture evenly inside.
- Prepare topping: In a small bowl, combine panko, olive oil, nutritional yeast, garlic powder, and smoked paprika.
- Add topping: Sprinkle the seasoned breadcrumb mixture evenly over the casserole.
- Bake: Place in the oven and bake at 375°F (190°C) for 25–30 minutes.
- Brown the top: Increase the oven to 400°F (205°C) for the final 3–5 minutes if needed, watching carefully until the topping becomes golden.
- Check the casserole: The edges should be bubbling and the center should look creamy but set rather than watery.
- Rest: Remove from the oven and let it stand for 5–10 minutes before serving.
- Garnish: Sprinkle with additional fresh parsley or nutritional yeast if desired.
- Serve: Spoon onto plates and serve warm alongside your favorite vegan protein.
High-Protein Cooking Tips
- Choose soy-based vegan cream cheese or another higher-protein plant-based option.
- Add cooked lentils or finely chopped white beans to the filling for a substantial protein boost.
- Serve alongside grilled tofu, tempeh, seitan, or a bean-based main dish.
- Use nutritional yeast for extra savory flavor and a modest protein contribution.
- For a lower-carb version, replace panko with crushed almonds, hemp seeds, or a suitable low-carb topping.
- Don’t skip squeezing the zucchini, especially when adding protein-rich ingredients that may also contribute moisture.
