- Garlic Powder: Lends savory depth without overpowering the fresh veggies.
- Dried Thyme: Brings a hint of herby brightness that pairs beautifully with summer squashes.

How to Make Roasted Summer Squash
Step 1: Prep Your Oven and Baking Sheet
Set yourself up for success by preheating your oven to 425°F (220°C). Either line a baking sheet with parchment paper for easy cleanup or lightly grease it to prevent sticking. Getting the pan hot and ready makes all the difference for beautiful browning.
Step 2: Slice the Squash
Grab your yellow squash and zucchini, then slice them into sturdy 1/4-inch rounds. Keeping the slices uniform helps everything roast evenly—plus, they look lovely all mingled together on the pan.
Step 3: Toss with Seasonings
In a big mixing bowl, combine the squash rounds with olive oil, garlic powder, dried thyme, salt, and black pepper. Don’t be shy—use your hands to toss so every slice gets glossy and beautifully seasoned. Trust me, this is where the flavor magic happens.
Step 4: Arrange and Roast
Spread the seasoned squash out in a single, even layer over your prepared baking sheet. Pop it into the hot oven and roast for 20 to 25 minutes, flipping halfway. You’re looking for edges that are golden brown and a texture that’s perfectly tender yet not mushy.
Step 5: Add Parmesan and Garnish
If you’re feeling cheesy, sprinkle the Parmesan over the squash during the final 5 minutes so it melts and crisps up just right. When everything’s hot from the oven, finish with chopped fresh parsley for a burst of color and freshness. Serve your Roasted Summer Squash immediately while it’s at peak flavor!
How to Serve Roasted Summer Squash

Garnishes
A finishing touch can turn this side into something especially memorable. Fresh parsley brings a pop of color and a hint of earthiness, while just a pinch of flaky sea salt or a squeeze of lemon elevates the roasted flavors even more. For an extra layer of flavor, try scattering a few toasted pine nuts or a light shower of grated lemon zest right before serving your Roasted Summer Squash.
Side Dishes
This recipe is a natural alongside grilled meats, seared fish, or even mixed grain bowls. Try pairing Roasted Summer Squash with a Mediterranean-inspired spread of herby grilled chicken, hummus, and warm pita, or keep things classic with roasted potatoes and a crisp garden salad. It’s versatile enough to tag along with whatever’s on your summer table.
Creative Ways to Present
Let your Roasted Summer Squash shine in new ways: pile it onto crostini for an easy appetizer, toss it with pasta for a vibrant seasonal main, or stir it into a frittata for a brunch twist. You can even layer leftovers in a grain bowl, add it to a veggie sandwich, or fold it into a cheesy quesadilla for a totally fuss-free lunch.
Make Ahead and Storage
Storing Leftovers
If you end up with extra Roasted Summer Squash, let it cool completely, then store it in an airtight container in the fridge. It’ll keep well for up to three days without losing its tender bite, making it great for easy additions to salads or meal prep bowls through the week.
Freezing
While freezing is possible, roasted squash’s texture can get softer after thawing. If you do freeze, spread the cooled squash on a baking sheet, freeze until solid, then transfer to a zip-top bag. Use within two months, keeping in mind it’s best for soups, casseroles, or blended dips after thawing.
Reheating
To restore a bit of that fresh-from-the-oven crispness, spread the squash on a baking sheet and reheat in a 400°F oven for about 6 to 8 minutes. For a quicker fix, a skillet over medium heat works well, or give it a short burst in the microwave if you’re just aiming to warm through.
FAQs
Can I use only zucchini or only yellow squash?
Absolutely! The recipe is flexible—use all zucchini, all yellow squash, or any combination depending on what you have. Just keep the total amount consistent for even roasting.
What other herbs work well in Roasted Summer Squash?
Besides thyme, you can experiment with Italian seasoning, dried oregano, rosemary, or even fresh basil added right after roasting for a fragrant finish.
How can I make the squash crispier?
For extra crispness, try broiling the squash for the last two or three minutes of roasting. Also, don’t overcrowd the pan—good air flow ensures beautiful golden edges.
Is Roasted Summer Squash healthy?
Definitely! It’s low in calories, carbs, and fat, plus it’s high in fiber and vitamins. With minimal oil and the option to skip the cheese, it’s a wonderfully wholesome addition to almost any meal.
Can I add other vegetables?
Yes! Bell peppers, eggplant, red onion, or cherry tomatoes can join the tray for a colorful medley. Just cut them into pieces similar in size to the squash for even cooking.
