Preparation Phase & Tools to Use
Essential Kitchen Tools
- Baking Dish: An 8”x8” or 8”x11” dish works best for even cooking.
- Sharp Knife: Helps slice zucchini evenly to ensure uniform baking.
- Cutting Board: Provides a stable surface for slicing vegetables.
- Mixing Bowl: For evenly combining the ingredients.
- Grater: If using block cheese, freshly grated cheese melts better.
Preparation Tips
- Slice Evenly: Cut zucchini and yellow squash into uniform slices or half-moons to ensure even cooking.
- Avoid Excess Moisture: Zucchini releases water as it bakes. Lightly salting it beforehand and patting it dry with a paper towel can help.
- Use Fresh Herbs: Fresh basil adds a more vibrant flavor compared to dried herbs.
- Grate Your Own Cheese: Pre-shredded cheese often contains anti-caking agents that prevent smooth melting.
Ingredients
Vegetables & Herbs:
- 2 medium zucchini, sliced into rounds or half-moons
- 2 medium yellow squash, sliced into rounds or half-moons
- 4 tablespoons fresh basil, chopped
- 2 tablespoons green onion, thinly sliced
Seasonings & Cheese:
- ½ teaspoon dried thyme
- ¾ teaspoon garlic powder
- Salt and freshly ground black pepper, to taste
- 1 cup grated mozzarella cheese, divided
- ½ cup grated Parmesan cheese (plus extra for topping, optional)
Step-by-Step Cooking Instructions
1. Preheat the Oven
Preheat your oven to 350°F (180°C). Lightly grease a baking dish with olive oil or non-stick spray.
2. Prepare the Vegetables
Wash the zucchini and yellow squash thoroughly. Slice them into rounds or half-moons for better layering. Chop the fresh basil and thinly slice the green onions.
3. Mix the Ingredients
In a large mixing bowl, combine:
- Sliced zucchini and yellow squash
- Chopped basil and green onions
- Dried thyme, garlic powder, salt, and black pepper
- ½ cup grated mozzarella and ½ cup grated Parmesan
Stir everything until well combined, ensuring the seasonings and cheese coat the vegetables evenly.
4. Bake the Casserole
Transfer the mixture into the prepared baking dish. Spread it evenly. Bake uncovered for 25-30 minutes, or until the zucchini is mostly tender when pierced with a fork.
5. Add the Cheese Topping
Remove the baking dish from the oven. Sprinkle the remaining ½ cup of mozzarella cheese over the top, along with extra Parmesan if desired.
Return the dish to the oven and bake for 10-15 more minutes, until the cheese is melted and golden brown.

Common Mistakes & How to Avoid Them
1. Zucchini Becoming Too Watery
Zucchini naturally contains a lot of water, which can make the bake too soft. To prevent this:
- Lightly salt the zucchini slices and let them sit for 10-15 minutes before baking. This draws out excess moisture, which can then be patted dry with a paper towel.
- Avoid over-stirring the ingredients, as this can release more water.
2. Overcooking the Zucchini
If the zucchini is baked too long, it can become mushy.
- Bake until just tender, checking at the 25-minute mark.
- If you prefer a firmer texture, slice the zucchini slightly thicker.
3. Cheese Not Melting Properly
Pre-shredded cheese often contains anti-caking agents that prevent it from melting smoothly.
- For the best results, use freshly grated cheese.
4. Underseasoning the Dish
Zucchini has a mild flavor, so proper seasoning is important.
- Adjust seasonings to taste before baking.
- Fresh herbs, red pepper flakes, or a dash of smoked paprika can enhance the flavor.
Best Side Dish Pairings
1. Garlic Butter Shrimp
The rich, cheesy zucchini pairs well with buttery, garlicky shrimp for a flavorful meal.
2. Roasted Brussels Sprouts
The crispiness of roasted Brussels sprouts adds texture contrast to the soft zucchini.
3. Cauliflower Rice
A great low-carb alternative to traditional rice that soaks up the cheesy flavors.
4. Simple Green Salad with Lemon Dressing
A light and refreshing salad balances the richness of the cheese.
5. Creamy Tomato Soup
The acidity of tomato soup complements the creamy, cheesy flavors of the bake.
6. Mashed Cauliflower
A comforting side dish that keeps the meal low-carb while adding creaminess.
7. Grilled Chicken Breast
A lean protein option that pairs well with the mild zucchini and cheese.
8. Keto Dinner Rolls
For those looking for a bread option, low-carb dinner rolls make a great addition.
