Yellow squash has a reputation problem. Bland. Mushy. The vegetable that gets pushed around every dinner plate by every kid (and most adults, let’s be honest). I GET IT. I was a squash skeptic for YEARS.
Then I figured this out: slice it thick (1/2 inch rounds, don’t go thinner), toss with olive oil and garlic powder, and let a hot oven do the actual work. Pile on the parmesan for salty crispy edges, a pinch of red pepper flakes for some heat, fresh parsley on top so it looks like you made an effort.
20 minutes. One sheet pan. A side dish that actually earns its spot on the table.
How to Get Golden, Not Soggy, Squash
Slice yellow squash into 1/2-inch thick rounds. UNIFORM slices roast evenly without sogginess.
Toss with olive oil and seasonings. EVERY piece must be coated.
Arrange in a single layer on a baking sheet. NO overlapping! This lets hot air circulate.
Roast at 400°F for 12-14 minutes until edges caramelize. Then broil for 1-2 minutes for a golden crust. WATCH carefully (it burns fast!)
The Broiler Trick for Crispy Parmesan
- Move the oven rack to the TOP slot…. roughly 5-6 inches from the broiler element. Bottom rack gives you limp, rubbery cheese.
- Switch to BROIL on HIGH for just 1-2 minutes at the end. Anything longer and you’re risking it.
- Sprinkle the Parmesan in a thin, even layer on each slice. Thick clumps stay gummy in the middle while the edges scorch.
- Stay glued to the oven door. Cheese flips from GOLDEN to BURNT in about 30 seconds flat.
- Pull the tray the INSTANT you see that golden color. Carry-over heat keeps crisping it on the counter, so don’t wait!
- Dab a tiny bit of butter on each round right after broiling. It melts right into the cheese…. (optional but a solid move)
What to Serve with Roasted Squash
Roasted yellow squash plays well with just about anything, but here are the BEST pairings.
- GRILLED chicken or pork chops (the parmesan-pepper combo cuts through rich meats beautifully)
- BAKED salmon or any white fish (light enough to let the squash shine)
- PASTA with olive oil or cream sauce (skip tomato-based ones, they fight the garlic)
- ROASTED potatoes or rice pilaf for a meatless plate
- CRUSTY bread for sopping up the cheesy bits left on the pan…. don’t waste them!

Ingredients
For the squash:
- 1 lb squash (sliced into 1/2-inch thick rounds for even roasting)
- 1.5 tbsp olive oil
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/2 tsp garlic powder
For the topping:
- 4 tbsp parmesan
- 1/4 tsp red pepper flakes
- 1 tbsp fresh parsley (chopped)
Step 1: Slice and Season the Squash
- 1 lb squash, sliced into 1/2-inch rounds
- 1.5 tbsp olive oil
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/2 tsp garlic powder
Slice the yellow squash into 1/2-inch thick rounds—this uniform thickness ensures even roasting and prevents some pieces from burning while others remain undercooked.
In a large bowl, toss the squash slices with olive oil, salt, black pepper, and garlic powder until every piece is evenly coated.
I like to use my hands for this step to ensure the seasonings are distributed evenly throughout, which really brings out the flavor.
Step 2: Layer and Top with Cheese
- seasoned squash from Step 1
- 4 tbsp parmesan
- 1/4 tsp red pepper flakes
Preheat your oven to 400°F.
Arrange the seasoned squash slices in a single layer on a baking sheet, making sure they’re not overlapping—this allows hot air to circulate around each piece for even browning.
Sprinkle the Parmesan cheese evenly over the top of each slice, and finish with a light dusting of red pepper flakes for a subtle heat and complexity.
Step 3: Bake and Caramelize
- prepared squash from Step 2
Roast the squash in the preheated 400°F oven for 12-14 minutes until the edges begin to caramelize and the squash is fork-tender.
I find that broiling for just 1-2 minutes at the end gives the cheese a beautiful golden crust and adds a nice toasted flavor—just watch it carefully so it doesn’t burn.
Remove from the oven and let cool for 1-2 minutes before serving.
Step 4: Garnish with Fresh Herbs
- roasted squash from Step 3
- 1 tbsp fresh parsley, chopped
Transfer the roasted squash to a serving dish and top with fresh chopped parsley for brightness and color.
Serve immediately while the squash is still warm and the cheese is creamy.
