On the whole, let me be frank, this is a recipe I get down to when I want to impress someone without bothering myself much. The first time I made it, I was very surprised to see how quickly the roasted Parmesan squash slices disappeared from the baking sheet. The squash becomes tender inside, sweet with an almost caramelized taste on the outside, while the edges just get crisped up, and that golden Parmesan crust? Addictive.

The slices would be classified as half veggie side and half crunchy snack. You have all the cosy, roasted flavours of the squash, then topped with a salty, nutty kick from the Parmesan. Very easy to prepare, and it satisfies true cravings while at the same time getting in on weeknight dinners just as well as on feasts during the holiday.

But the best part is that anybody can make this dish. Not much in the way of chef skills required: just slice, sprinkle, and roast. And the end result is something you’d be glad to serve guests, or just snack on right off the tray (no judgment—I admit to doing that probably way more times than I’d like to count).

Why You’ll Love This Recipe

Here’s why I think you’re going to fall for these roasted Parmesan squash slices:

Crispy and cheesy – the edges turn golden-brown and irresistible.
Healthy comfort food – you get veggies with a side of indulgence.
Fast and easy, roasting will take only 20 minutes.
Minimal ingredients: Squash, oil, Parmesan, and a few seasonings.
Very versatile-works as a side, appetiser, or as a light snack.

Tools You’ll Need

Think of these as your helpers in the kitchen. Nothing fancy, just the basics that make life easier:

Baking sheet (or sheet pan) – where all the magic happens in the oven.
Sharp knife – for slicing the squash evenly (even slices = even cooking).
Cutting board – your chopping station.
Mixing bowl – to toss the squash with oil and seasonings.
Measuring cups and spoons – for getting the Parmesan and spices just right.
Parchment paper or foil (optional) – keeps cleanup stress-free.

Ingredients

Here’s everything you’ll need, with both US and metric measurements:

2 medium yellow squash or zucchini (about 1 lb / 450 g)
2 tbsp olive oil (30 ml)
½ cup grated Parmesan cheese (50 g) – the real deal, freshly grated, makes a difference
½ tsp garlic powder (or more if you love garlic)
½ tsp paprika (smoky or sweet, your choice)
Salt and black pepper, to taste
Optional: fresh parsley or basil for garnish

Step-by-Step Instructions

Preheat the Oven to 425°F-220°C. The hot oven is what makes them crispy on the edges.
Prepping the Squash: Wash and dry the squash, then slice it into rounds about ¼-inch (0.6 cm thick. Try to keep them as uniform in size as possible, so they roast evenly.
Toss with Oil and Spices: Put the sliced squash in a mixing bowl along with the olive oil, garlic powder, paprika, salt, and pepper. Toss to coat well.
Arrange on Baking Sheet: Spread these slices out in a single layer. Overlapping keeps them from roasting and steams them, so let them breathe!
Sprinkle with Cheese: Generously top each slice with Parmesan cheese. Don’t worry if some gets on the tray, as these annoying little bits are the crispy, cheesy treats that you want to eat later!
Roast Until Golden: Cook for 18-22 minutes until golden, turning over midway through for an extra even browning, if desired. You are looking for tender on the inside, golden, and crispy on the outside.
Serve Hot: Put onto a plate (or eat right off the tray, which I do). Garnish with some fresh herbs if you’re feeling extra fancy.

Serving Ideas

These are sides with roasted chicken, a steak, or grilled fish.
A snack with a little marinara for dipping on the side.
An appetiser for a party, all laid out on a platter with toothpicks.

Variations and Customisation

Cheese replacement- Switch Pecorino Romano or Asiago for sharper biting.
Add spice- Heat it with a pinch of red pepper flakes.
Herb twist- Before roasting, put in dried Italian seasoning.
Low-carb “party foods”- cut thinner for a crispier, snack-type presentation.

Storage and Make-Ahead

Storage- Store leftovers in an airtight container in the fridge for up to 3 days.
Reheat in the Oven or Air fryer to regain crispiness. Microwave works, but they’re softer.
Make it ahead of time, slice and season the squash earlier in the day, and just cheese it up and roast before serving.

Pro Tips (and Mistakes to Avoid)

Let me share a few things I’ve learned the hard way so you don’t have to:

Don’t overcrowd the pan, seriously, give them space. Crowding = soggy squash.
Freshly grated Parmesan is the best. The one pre-shredded has anti-caking agents, which don’t melt quite so well.
Cut evenly- if you don’t do that, some will end up burnt while others will be completely undercooked.
Flip halfway for extra crisp- not essential, but just makes them even better.
