You can roast zucchini and yellow squash in the oven at 425°F for about 20 to 25 minutes, and the result is tender, caramelized, and downright delicious.
If you’ve ever wondered how to roast zucchini and yellow squash so they come out perfectly golden instead of soggy, you’re in the right place.
Roasting zucchini and yellow squash is one of the easiest ways to turn these abundant summer vegetables into a side dish everyone actually wants to eat.
The high heat pulls out their natural sweetness while giving the edges that crisp, browned texture we all love.
In this post, we’ll walk through exactly how to roast zucchini and yellow squash, from prep to seasoning to serving.
Let’s dive in.
How Do You Roast Zucchini and Yellow Squash?
When you roast zucchini and yellow squash, the key is high heat, quick timing, and not crowding the pan.
Here’s how the process works step by step.
1. Preheat the Oven to 425°F
You want the oven fully hot before the zucchini and yellow squash go in.
A hot oven sears the outside quickly before the inside turns mushy.
If your oven runs cool, bump it to 450°F and keep an eye on things.
2. Slice the Zucchini and Yellow Squash Evenly
Cut both the zucchini and yellow squash into half-inch rounds or half-moon slices.
Even slices matter because uneven pieces roast at different speeds.
If you slice zucchini and yellow squash too thin, they’ll burn before they caramelize.
Too thick, and they’ll steam instead of roast.
3. Toss With Oil and Seasonings
Drizzle the zucchini and yellow squash with two tablespoons of olive oil.
Toss until every piece is lightly coated, then season with salt, pepper, and garlic powder.
You can also add dried oregano, smoked paprika, or a pinch of red pepper flakes.
4. Spread Them in a Single Layer
Arrange the zucchini and yellow squash on a sheet pan in one even layer.
If the pieces overlap, they’ll trap moisture and steam rather than roast.
Use two pans if you need to—this step makes or breaks the texture.
5. Roast for 20 to 25 Minutes
Roast the zucchini and yellow squash until the edges are golden brown.
Flip them once halfway through so both sides get that caramelized finish.
They’re done when a fork slides in easily but they still hold their shape.
Tips for the Best Roasted Zucchini and Yellow Squash
A few small tweaks make a big difference when you roast zucchini and yellow squash.
1. Salt Them First to Remove Excess Water
Zucchini and yellow squash are mostly water, which is why they can turn soggy.
Sprinkle the slices with salt and let them sit for 15 minutes.
Pat them dry with a paper towel before roasting.
This one trick helps roasted zucchini and yellow squash stay firm and caramelize beautifully.
2. Don’t Skip the High Heat
Roasting zucchini and yellow squash at 425°F or higher is what gives you browning.
Lower temperatures draw out moisture slowly and leave you with limp, pale slices.
3. Give Them Space
Crowding is the number one reason roasted zucchini and yellow squash turn out mushy.
Leave a little gap between each piece so the heat can circulate.
4. Add Parmesan or Herbs at the End
If you want to level up your roasted zucchini and yellow squash, finish them with grated Parmesan.
Return the pan to the oven for the last three minutes so the cheese melts.
Fresh basil or parsley sprinkled after roasting adds a bright finish too.
What to Serve With Roasted Zucchini and Yellow Squash
Roasted zucchini and yellow squash pair with almost anything.
Serve them alongside grilled chicken, roasted salmon, or a hearty pasta dish.
They also work great in grain bowls, on top of flatbread, or tossed into warm salads.
And if you have leftovers, roasted zucchini and yellow squash keep in the fridge for up to four days.
Just reheat them in a hot skillet instead of the microwave to keep that roasted texture.
So, How Do You Roast Zucchini and Yellow Squash?
You roast zucchini and yellow squash by slicing them evenly, tossing with oil and seasonings, spreading them in a single layer, and baking at 425°F for 20 to 25 minutes.
Salting them first and giving them space on the pan keeps them from turning soggy.
Whether you’re working with a bumper crop from the garden or a bag from the farmers market, this method makes roasted zucchini and yellow squash a side dish you’ll come back to all summer long.
