I remember the first time I tried roasting squash at home it was late autumn, and the leaves outside were painting the neighborhood in shades of gold and amber. I wanted a dish that felt a little fancy but didn’t require hours in the kitchen. Parmesan came to mind. Its nutty, savory flavor seemed perfect for elevating the natural sweetness of the squash.
As I thinly sliced the squash and arranged it on a baking sheet, I could already imagine the aroma filling my kitchen. Drizzling olive oil and sprinkling Parmesan felt almost like a ritual, and I could hardly wait to see the golden, crispy edges that would emerge from the oven. Fifteen minutes later, the squash was perfectly crisp on the edges, tender inside, and shimmering with melted Parmesan.
Crispy Parmesan Roasted Squash quickly became my go to for festive dinners, cozy weeknights, or even as a sophisticated snack. It’s simple enough for casual home cooks but feels indulgent enough to impress guests. And the best part? It pairs beautifully with so many other dishes, making it versatile for almost any occasion.
Short Description
A simple, elegant roasted squash recipe with crispy edges and a rich Parmesan flavor, perfect as a festive side dish or a healthy everyday treat.
Key Ingredients
- 2 medium yellow squash or zucchini, thinly sliced
- 1 tablespoon olive oil
- Salt, to taste
- Black pepper, to taste
- 1/3 cup grated Parmesan cheese
Tools Needed
- Baking sheet
- Parchment paper
- Knife and cutting board
- Measuring spoons and cups
Cooking Instructions
Step 1: Preheat the oven
Preheat your oven to 425°F (220°C) to ensure it reaches the perfect temperature for crispy edges and golden Parmesan.
Step 2: Prepare the baking sheet
Line a baking sheet with parchment paper and lightly grease it with olive oil. This prevents sticking and helps the squash crisp evenly.
Step 3: Arrange the squash
Place the thinly sliced squash in a single layer on the prepared baking sheet. Avoid overlapping slices, or they might steam instead of roast.
Step 4: Season and top
Drizzle the olive oil evenly over the squash slices, then sprinkle with salt, black pepper, and grated Parmesan cheese. Make sure every slice gets a little coating for maximum flavor and crispiness.
Step 5: Bake
Bake for 15 minutes, keeping an eye on the edges. You’re looking for the Parmesan to turn a golden brown and the squash edges to crisp up slightly.
Step 6: Serve warm
Transfer the roasted squash to a serving platter and enjoy while warm for the best texture and flavor.

Solution: Bake for exactly 15 minutes; check frequently toward the end.

FAQs
