This Easy Cheesy Zucchini Bake takes about 20% less time than many traditional zucchini casseroles, which often require pre-cooking or draining steps. With minimal prep and hands-off baking, you’ll have a wholesome dish on the table in under an hour—perfect for busy weeknights or spontaneous gatherings.
Step-by-Step Instructions
Step 1: Prep the Oven and Dish
Preheat your oven to 350°F (180°C). Spray an 8″ x 8″ or 8″ x 11″ baking dish with olive oil or non-stick spray.
Tip: A slightly larger dish yields a crispier top layer.
Step 2: Slice and Prep the Veggies
Wash the zucchini and yellow squash thoroughly. Cut them into even slices or half-moons for uniform cooking.
Personalization Tip: Use a mandoline for ultra-thin slices if you prefer a more delicate texture.
Step 3: Chop the Herbs and Onions
Wash and dry the basil (a salad spinner works wonders). Finely chop or slice the basil and thinly slice the green onions.
Tip: Herb scissors make quick work of basil leaves and prevent bruising.
Step 4: Mix the Base
In a large bowl, combine the sliced zucchini, yellow squash, basil, green onions, dried thyme, garlic powder, 1/2 cup mozzarella, and 1/2 cup Parmesan. Stir until the veggies are well coated with cheese and the herbs are evenly distributed. Season generously with salt and black pepper.
Actionable Tip: Toss the mixture gently to avoid breaking the squash slices.
Step 5: Assemble and Bake
Transfer the mixture to your prepared baking dish. Bake uncovered for 25-30 minutes. Check doneness by piercing a piece of zucchini with a fork—it should be mostly tender.
Step 6: Add the Cheesy Topping
Remove the dish from the oven. Sprinkle the remaining 1/2 cup of mozzarella and a little extra Parmesan over the top. Return to the oven and bake for another 10-15 minutes, or until the cheese is melted, golden, and bubbly.
Step 7: Serve and Enjoy
Let the bake cool for a few minutes before serving. Enjoy hot, straight from the oven, for the best flavor and texture.
Pro Tip: Leftovers taste even better the next day as the flavors meld together in the fridge.

Common Mistakes to Avoid
- Skipping the Salting Step: Not salting the zucchini can lead to excess moisture and a watery bake.
Solution: Lightly salt and let the slices sit for 10 minutes, then blot dry. - Overbaking: Zucchini cooks quickly; overbaking can result in mushy texture.
Solution: Check doneness at the 25-minute mark. - Uneven Slices: Thick or uneven slices may cook unevenly.
Solution: Use a sharp knife or mandoline for uniformity. - Too Much Cheese: While tempting, excessive cheese can overwhelm the delicate flavor of the squash.
Solution: Stick to recommended amounts or adjust to taste.

Storing Tips for the Recipe
- Refrigeration: Store leftovers in an airtight container in the fridge for up to 3 days.
Best Practice: Let the bake cool completely before storing to prevent condensation. - Freezing: Not recommended, as zucchini can become watery and lose texture after thawing.
- Meal Prep: Prep the veggie and cheese mixture ahead of time and refrigerate. Assemble and bake when ready to serve.
- Reheating: Warm in the oven at 325°F (160°C) until heated through for best texture. Microwave works for quick reheating but may soften the veggies further.
