What is Hasselback Zucchini?
Hasselback zucchini is made by slicing zucchini into thin sections without cutting all the way through. As it roasts, the slices fan out slightly, creating the perfect place for seasonings, butter, cheese, and herbs to settle into every bite.
The result is a zucchini side dish that has much more flavor and texture than traditional roasted zucchini rounds.
Ingredients You’ll Need
- 4 medium zucchini
- 4 tablespoons melted butter
- 1 tablespoon olive oil
- 6 garlic cloves, finely minced
- 1 teaspoon Italian seasoning
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
- ¾ cup freshly grated Parmesan cheese
- 2 tablespoons chopped fresh parsley
How to Make Insanely Good Garlic Parmesan Hasselback Zucchini
Step 1: Prepare the zucchini
Preheat your oven to 400°F.
Place each zucchini between two wooden spoons or chopsticks. Using a sharp knife, slice thin cuts about ⅛-inch apart, stopping when your knife reaches the spoon handles so the zucchini remains intact.
Step 2: Make the garlic butter
In a small bowl, whisk together the melted butter, olive oil, garlic, Italian seasoning, salt, and pepper.
Step 3: Season the zucchini
Arrange the zucchini in a baking dish. Brush the garlic butter mixture generously over the zucchini, allowing some of the garlic to work its way down into the slices.
Step 4: Roast
Bake for 20 minutes.
Remove from the oven and sprinkle the Parmesan cheese over the zucchini. Gently tuck some of the cheese into the sliced sections.
Step 5: Finish baking
Return the zucchini to the oven and bake for another 10 to 15 minutes until tender and golden brown.
Step 6: Garnish and serve
Sprinkle with fresh parsley and serve immediately while hot and cheesy.
