Let’s dive in.
 

How to Roast Zucchini and Yellow Squash in the Oven

Roasting zucchini and yellow squash in the oven is simple, and here’s exactly how to do it:
 

1. Preheat the Oven to 425°F

A hot oven is the secret to roasting zucchini and yellow squash that come out golden instead of soggy.
 
At 425°F, the outside of the squash browns and caramelizes before the inside turns to mush.
 
If you roast zucchini and yellow squash at a lower temperature, they’ll release water and steam instead of roast.
 
So crank that oven up and let it fully preheat before the squash goes in.
 

2. Slice the Squash Evenly

Cut both the zucchini and yellow squash into rounds about 1/2 inch thick.
 
You can also cut them into half-moons or lengthwise spears if you prefer.
 
The key is keeping the pieces roughly the same size so they roast zucchini and yellow squash evenly.
 
If some pieces are thin and others are thick, the thin ones will burn while the thick ones stay raw.
 

3. Toss With Oil and Seasonings

Pat the slices dry with a paper towel first, since excess moisture is the enemy of roasting.
 
Then toss the zucchini and yellow squash with about two tablespoons of olive oil.
 
Season with salt, black pepper, garlic powder, and dried herbs like oregano, thyme, or Italian seasoning.
 
You can also add a pinch of red pepper flakes if you like a little heat.
 
Just make sure every piece gets coated so the seasoning sticks and the squash roasts evenly.
 

4. Spread Them in a Single Layer

Arrange the zucchini and yellow squash on a large baking sheet in a single layer.
 
Don’t crowd the pan, because when the pieces touch, they steam instead of roast.
 
If you have a lot of squash, use two baking sheets rather than piling them up.
 
This one step makes the biggest difference between crispy roasted zucchini and yellow squash and a sad, watery tray.
 

5. Roast for 20 to 25 Minutes

Slide the baking sheet into the oven and roast zucchini and yellow squash for about 20 to 25 minutes.
 
Flip them halfway through so both sides get that lovely golden color.
 
They’re done when the edges are browned and the centers are tender but not falling apart.
 
If you cut thicker pieces, give them a few extra minutes.
 

Best Tips for Roasting Zucchini and Yellow Squash

If you want to roast zucchini and yellow squash like a pro, keep these tips in mind:
 

1. Choose Firm, Small-to-Medium Squash

Smaller zucchini and yellow squash have fewer seeds and firmer flesh, which means they roast much better.
 
Large squash are watery and seedy, so they tend to turn mushy in the oven.
 
Look for squash that feel heavy for their size and have shiny, unblemished skin.
 

2. Salt Them First to Draw Out Water

If your squash feels especially watery, sprinkle the slices with salt and let them sit for 15 minutes.
 
Then pat them dry before tossing with oil.
 
This draws out excess moisture so the zucchini and yellow squash roast instead of steam.
 
It’s a small extra step that pays off big.
 

3. Use High Heat and a Hot Pan

A preheated baking sheet gives the squash a head start on browning.
 
Pop the empty sheet in the oven while it preheats, then carefully spread the zucchini and yellow squash onto the hot pan.
 
You’ll hear a little sizzle, and that sizzle is exactly what you want.
 

4. Don’t Skip the Flip

Flipping the pieces halfway through helps them roast zucchini and yellow squash evenly on both sides.
 
It also gives you a chance to check how quickly they’re browning.
 
Set a timer so you don’t forget, because these veggies go from golden to burnt fast.
 

5. Add a Finishing Touch

Once they’re out of the oven, finish the zucchini and yellow squash with a squeeze of lemon juice or a sprinkle of Parmesan.
 
Fresh herbs like basil or parsley add a bright, fresh note.
 
A drizzle of balsamic glaze works wonders too.
 

Common Mistakes When Roasting Zucchini and Yellow Squash

Avoid these common mistakes, and your roasted zucchini and yellow squash will turn out perfectly every time:
 

1. Overcrowding the Pan

This is the number one reason roasted zucchini and yellow squash turn out soggy.
 
When the pieces are piled together, they release steam and basically braise in their own juices.
 
Give them room to breathe and they’ll brown beautifully.
 

2. Cutting Them Too Thin

Paper-thin slices will burn before they ever get tender.
 
Aim for slices around 1/2 inch thick so the zucchini and yellow squash roast evenly.
 

3. Skipping the Drying Step

Moisture on the surface of the squash prevents browning.
 
Patting the slices dry before roasting zucchini and yellow squash helps them crisp up nicely.
 

4. Using Too Little Oil

Oil helps the seasonings stick and encourages browning.
 
Too little oil means dry, bland squash, so don’t be shy with that drizzle.
