- 1/2 teaspoon garlic powder: Imparts a warm, savory kick that deepens the flavor profile.
- 1/2 teaspoon dried thyme: Brings earthy, herbaceous notes that complement the squash wonderfully.
- 1/2 teaspoon salt: Enhances all the other flavors, making each bite pop.
- 1/4 teaspoon black pepper: Adds a subtle heat and complexity to the dish.

How to Make Roasted Summer Squash Recipe
Step 1: Prep Your Oven and Pan
Start by preheating your oven to 425°F (220°C). This high heat is perfect for roasting vegetables quickly to a tender, caramelized finish. Line a baking sheet with parchment paper or lightly grease it to prevent sticking and make clean-up easier.
Step 2: Slice the Squash
Next, slice both the yellow squash and zucchini into 1/4-inch thick rounds. This thickness ensures they cook evenly and become tender without falling apart. Having uniform slices helps them roast at the same speed and develop a beautiful golden color.
Step 3: Toss with Seasonings
Place the sliced squash in a large bowl and drizzle with olive oil. Sprinkle garlic powder, dried thyme, salt, and black pepper over the top. Toss everything gently but thoroughly, making sure each piece is well coated in oil and spices. This step builds the flavorful foundation you’ll taste in every bite.
Step 4: Roast the Vegetables
Spread the coated squash slices out in a single layer on your prepared baking sheet. It’s important they don’t overlap so they can roast evenly and get that lovely caramelization. Pop the tray into the oven and roast for 20 to 25 minutes. About halfway through cooking, flip the slices so both sides brown nicely.
Step 5: Add Parmesan Cheese
If you’re using Parmesan, sprinkle it over the squash during the last 5 minutes of roasting. This gives the cheese time to melt and crisp slightly, adding an irresistible savory finish without overpowering the squash’s natural flavors.
Step 6: Garnish and Serve
Once out of the oven, garnish your Roasted Summer Squash Recipe with freshly chopped parsley if desired. This fresh herb adds brightness and a lovely contrast to the warm roasted notes. Serve the squash hot, straight from the pan for best flavor.

Garnishes
A sprinkle of fresh parsley is a simple but beautiful way to finish this dish—adding a hint of color and fresh, herbal flavor. You can also try a few red pepper flakes if you enjoy a bit of heat. For a final flourish, a drizzle of lemon juice or a bit of grated lemon zest brightens the flavors even more.
Side Dishes
This Roasted Summer Squash Recipe pairs wonderfully with a wide range of meals. It complements grilled chicken or fish perfectly, making it an ideal side for summer barbecues. It also works well alongside grains like quinoa or rice or tossed into a simple pasta dish for a light yet flavorful component.
Creative Ways to Present
Want to impress? Arrange the roasted squash slices in pretty overlapping circles on a platter. You could also layer them in a glass casserole dish with fresh mozzarella and tomato slices for a show-stopping summer vegetable gratin. Alternatively, toss the roasted pieces into a salad or use them as a topping for crostini with ricotta or goat cheese.
Make Ahead and Storage
Storing Leftovers
You can keep leftover roasted summer squash in an airtight container in the refrigerator for up to 3 days. The flavors develop even more after a day, making leftovers perfect for adding to sandwiches, salads, or quick pasta dishes.
Freezing
Roasted summer squash doesn’t freeze especially well because the texture can become mushy upon thawing. For best results, it’s ideal to enjoy this dish fresh or within a few days stored in the fridge.
Reheating
To reheat, pop the squash slices onto a baking sheet and warm them in a 350°F oven for about 10 minutes. This method helps restore some of the initial crispness. Avoid microwaving if you want to keep as much texture as possible.
FAQs
Can I use other types of squash in this recipe?
Absolutely! Summer squash varieties like pattypan or even delicata squash work beautifully. Just slice them about the same thickness for consistent roasting.
Is this recipe vegan?
This Roasted Summer Squash Recipe is vegan if you skip the Parmesan cheese or use a plant-based alternative. The dish is naturally gluten-free and low-carb as well.
Can I add fresh garlic instead of garlic powder?
You can, but keep in mind fresh garlic might brown and burn more quickly in the oven. To prevent this, use finely minced garlic and toss it with the squash right before roasting or add it halfway through roasting.
How do I get the squash extra crispy?
For an extra crisp texture, try broiling the squash for the last 2 to 3 minutes of cooking. Just keep a close eye so they don’t burn!
Can I make this recipe gluten-free?
Yes! This recipe is naturally gluten-free since it only uses fresh vegetables, seasonings, and optional cheese, making it a safe and healthy option for gluten-sensitive diets.
