Garlic Parmesan Roasted Zucchini is the easiest answer when I want something bold and comforting but still light on carbs. The rich flavor of browned cheese and zesty garlic transforms plain zucchini into the sort of side dish that disappears in seconds next to roast chicken or pasta. I keep this recipe on steady rotation for weeknight dinners and potlucks alike because it wins over even the biggest veggie skeptics.
When I first served this at game night everyone asked for the recipe before the meal even ended. Now whenever zucchini shows up in my CSA box I know just what to do with it.
Ingredients
- Zucchini: Choose medium sized with glossy green skin for the best texture and flavor
- Melted butter: Brings richness and helps everything crisp up in the oven go for unsalted to control the salt level
- Parmesan: Freshly grated melts and browns the best creating delicious cheesy bits
- Minced garlic or garlic powder: Adds big bold flavor use fresh garlic for a spicy bite or powder for convenience
- Black pepper: Fresh cracked gives the most aromatic kick
- Paprika: Gives a little smoky depth and beautiful golden color use sweet or smoked depending on your taste
- Salt: Brings out all the flavors choose fine sea salt for even seasoning
- Italian seasoning: Lends herby complexity use your favorite blend with lots of basil and oregano
- Fresh parsley: Chopped and scattered on top for a bright finishing touch
Step-by-Step Instructions
- Prep the Zucchini:
- Wash zucchini thoroughly. Cut a thin slice off the bottom of each zucchini so it will not roll away. Place it between two chopsticks and make even crosswise slices every one quarter inch stopping when the knife hits the sticks so you do not cut all the way through. The result should look like an accordion of zucchini.
- Butter and Arrange:
- Transfer the sliced zucchini to a baking dish making sure they are snug but not crowded. Pour the melted butter all over and gently brush it into the slices making sure it sinks between each cut. This gives a tender inside and crisp bottom.
- Mix the Seasoning:
- In a bowl combine Parmesan minced garlic black pepper paprika salt and Italian seasoning. Use your fingers to break up any clumps the mixture should be evenly combined and ready to sprinkle.
- Season the Zucchini:
- Sprinkle the Parmesan mixture generously over the zucchini and rub shimmy it into the slices so flavor gets between every piece. Do not skip this detail it is the difference between bland and craveable results.
- Roast to Perfection:
- Bake in a preheated oven at 400 degrees F for twenty five to thirty minutes. Check that the cheese is golden and crisp and the zucchini feels just tender when pierced with a fork. If you like extra browning set under the broiler for one or two minutes right at the end.
- Add Garnish and Serve:
- Scatter fresh chopped parsley on top for color and freshness. Serve straight from the oven while everything is still sizzling and aromatic.

My favorite part is how the Parmesan crisps on the baking dish edges. That golden cheesy crust always has me sneaking an extra piece before dinner even gets to the table. This was the first dish I taught my cousin to make and now she brings it to every family get together.
Storage Tips
Let leftovers cool completely before storing in an airtight container. Keep in the refrigerator for up to three days. For best results reheat in an oven or air fryer which will restore the zucchini’s crispness. Avoid microwaving as it makes everything soggy. This dish is best enjoyed fresh and is not freezer friendly.
Ingredient Substitutions
If you do not have Parmesan try grated Pecorino Romano or Asiago for similar salty cheesy goodness. Vegan guests can enjoy this with a plant based buttery spread and nutritional yeast instead of cheese. For more heat add red pepper flakes or a pinch of cayenne. Smoked paprika brings a deeper flavor if you want a twist.
Serving Suggestions
Serve alongside grilled or roasted proteins for a balanced meal. It fits beautifully next to lemony chicken fish or even your favorite Italian main like baked ziti. Sometimes I pile leftovers onto a toasty sandwich with a swipe of pesto for a next day lunch that truly hits the spot.

Cultural and Historical Context
Roasting zucchini with cheese and herbs is a European staple especially in Mediterranean and Italian kitchens where summer squash is abundant. The accordion slicing resembles the classic Hasselback potato technique which both increases surface area for browning and lets flavors soak into every gap. This recipe is a modern weeknight spin on those age old traditions.
