Ingredients You’ll Need

Zucchini

4 medium zucchini, sliced into 1/4-inch rounds
- Choose firm zucchini with shiny skin and no soft spots.
- Smaller zucchini taste sweeter and less watery than huge ones.

Creamy Parmesan sauce

1 cup heavy cream
- You can swap half-and-half for a lighter version, but the sauce turns slightly thinner.
1/2 cup sour cream
- Greek yogurt works in a pinch, but sour cream gives a smoother tang.
1 cup freshly grated Parmesan cheese, divided
- Use a block of Parmesan and grate it yourself for best melt and flavor.
1/2 cup shredded mozzarella cheese
- Any low-moisture mozzarella works; pre-shredded saves time.
3 cloves garlic, minced
- Garlic paste from a tube works if you need a shortcut.
2 tablespoons unsalted butter, melted
1 teaspoon Italian seasoning
1/2 teaspoon onion powder
1/2 teaspoon kosher salt, plus more to taste
1/4 teaspoon black pepper
Pinch of red pepper flakes (optional, for a little heat)

Topping

1/3 cup panko breadcrumbs
- Regular breadcrumbs work, but panko gives a better crunch.
2 tablespoons grated Parmesan cheese
1 tablespoon olive oil
1 tablespoon chopped fresh parsley (optional, for garnish)

Pantry shortcuts & brand notes

Use pre-shredded mozzarella and pre-grated Parmesan if you feel rushed, but freshly grated cheese melts smoother.
Use jarred minced garlic if you want to skip chopping.
Use store-brand heavy cream and sour cream; they usually work just as well as name brands.

Equipment

9×13-inch baking dish or similar size
Large mixing bowl
Sharp knife and cutting board
Measuring cups and spoons
Whisk or fork
Aluminum foil
Oven mitts
Small bowl for topping

Tips & Tricks

Salt the sliced zucchini lightly and pat dry after 10 minutes to reduce extra moisture and keep the sauce creamy.
Slice the zucchini evenly so they cook at the same rate and stay tender, not mushy.
Use freshly grated Parmesan for best flavor and browning on top.
Do not drown the zucchini in sauce; coat them well but still let them peek through for better texture.
Bake on the middle rack so the top browns nicely without burning.
Broil for 1 to 2 minutes at the end if you want extra golden, crispy cheese.
Let the dish rest 5 to 10 minutes before serving so the sauce thickens and does not run all over the plate.
Add cooked chicken or sausage to turn this side into a full meal.

How to Make Creamy Parmesan Baked Zucchini Recipe

Step 1: Prep the zucchini

Preheat your oven to 400°F and grease your baking dish with a little butter or oil. Wash the zucchini, trim the ends, and slice them into 1/4-inch rounds. Sprinkle them lightly with salt, let them sit 10 minutes, then pat them dry with paper towels to pull out some moisture.

Step 2: Mix the creamy Parmesan sauce

In a large bowl, whisk together heavy cream, sour cream, melted butter, garlic, Italian seasoning, onion powder, salt, pepper, and red pepper flakes. Stir in 3/4 cup of the Parmesan and all of the mozzarella until the mixture looks smooth and cheesy. Taste the sauce and adjust the salt or pepper if you want a stronger kick.

Step 3: Combine zucchini with sauce

Add the sliced zucchini to the bowl with the sauce. Toss gently with your hands or a big spoon so every slice gets a nice coating. Make sure the slices separate and do not clump so the sauce can reach all sides.

Step 4: Arrange in the baking dish

Spread the coated zucchini evenly in the prepared baking dish. Pour any extra sauce from the bowl over the top and spread it around. Sprinkle the remaining 1/4 cup Parmesan evenly over the surface.

Step 5: Mix the crunchy topping

In a small bowl, combine panko, 2 tablespoons grated Parmesan, and olive oil. Stir until the crumbs look evenly moistened and slightly clumpy. Sprinkle this mixture over the zucchini in an even layer.

Step 6: Bake until bubbly and golden

Cover the dish loosely with foil and bake for 15 minutes. Remove the foil and bake another 10 to 15 minutes until the zucchini turns tender and the top looks golden and bubbly. If you want deeper color, switch to broil for 1 to 2 minutes and watch closely so it does not burn.

Step 7: Rest and garnish

Take the baking dish out of the oven and let it rest 5 to 10 minutes. This short rest helps the creamy Parmesan sauce thicken and cling to the zucchini. Sprinkle with chopped parsley right before serving for a fresh pop of color.

Add a crisp green salad on the side to balance the richness and round out the meal.
