This dish features tender, roasted zucchini and squash, bringing out their natural sweetness and flavor. It’s colorful, healthy, and super easy to make!
I love to spice it up with a sprinkle of garlic and herbs. Perfect as a side or tossed in a salad. You can almost hear the veggies singing, “Eat me!” 🥒✨
Key Ingredients & Substitutions
Zucchini: Medium zucchinis are the star here! They are tender and mild, making them perfect for roasting. If you can’t find them, try using pattypan squash or other thin-skinned summer squash.
Yellow Squash: Similar to zucchini, yellow squash has a slightly different flavor but works wonderfully in this dish. If it’s unavailable, use more zucchini or another soft squash variety.
Tomatoes: Adding tomatoes is an optional yet colorful touch. For extra flavor and sweetness, cherry tomatoes work great too! If you prefer, skip them entirely or use sun-dried tomatoes for a different twist.
Olive Oil: I love using extra virgin olive oil for its flavor. If you’re looking for different options, avocado oil or melted coconut oil can also be good substitutes.
Herbs: Dried Italian herbs add a lovely mix of flavors. If you have fresh herbs, like basil or thyme, feel free to use them instead! Adjust the amounts to taste since fresh herbs can be more potent.
How Do I Ensure My Vegetables Roast Evenly?
To make sure your zucchini and squash roast perfectly, pay attention to how you prepare them before cooking. It’s all about the layering and space on your baking sheet!
- Slice the vegetables evenly to 1/2-inch thick rounds. This helps them cook at the same rate.
- Spread the veggies out in a single layer on the baking sheet. Avoid stacking them; this lets heat circulate and encourages even roasting.
- Flip the slices halfway through cooking for consistent browning on all sides.
- Keep an eye on the color! Look for a light golden brown and some caramelized edges. This signals they’re perfectly roasted!

How to Make Roasted Zucchini and Squash
Ingredients You’ll Need:
For the Veggies:
- 2 medium zucchinis, sliced into 1/2-inch thick rounds
- 2 medium yellow squashes, sliced into 1/2-inch thick rounds
- 1-2 medium tomatoes, sliced into thick rounds (optional for color and flavor)
For the Seasoning:
- 3 tablespoons olive oil
- 1 teaspoon garlic powder
- 1 teaspoon dried Italian herbs (or a mix of dried oregano, basil, and thyme)
- Salt and freshly ground black pepper, to taste
For Garnish:
- 2 tablespoons fresh parsley, finely chopped
How Much Time Will You Need?
This delicious recipe takes about 10 minutes for prep and about 20-25 minutes for roasting. In total, you’ll be just around 35-40 minutes from start to finish, making it a quick and easy side dish to prepare!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by setting your oven to 425°F (220°C). While that heats up, grab a baking sheet or roasting pan, and either line it with parchment paper or lightly grease it with some olive oil. This will help keep your veggies from sticking!
2. Prepare the Vegetables:
In a large mixing bowl, toss together the sliced zucchinis, yellow squashes, and optional tomato slices. Drizzle the olive oil over them, then add garlic powder, dried herbs, salt, and pepper. Use your hands or a spatula to mix everything until the vegetable slices are well coated in the seasoning.
3. Arrange on the Baking Sheet:
Take the seasoned vegetable mixture and spread it evenly across the prepared baking sheet. Make sure the slices are in a single layer and not overlapping—that way, they roast evenly and each slice gets nice and caramelized.
4. Roast the Vegetables:
Place the baking sheet into the preheated oven and roast the vegetables for about 20-25 minutes. Be sure to flip the slices halfway through to ensure they cook evenly. You’ll know they’re ready when they’re tender and have a light golden brown color. Yum!
5. Serve and Garnish:
Once they’re roasted to perfection, take the pan out of the oven and carefully transfer the vegetables to a serving dish. Sprinkle your freshly chopped parsley on top for a nice pop of color and added fresh flavor.
6. Enjoy!
Serve your roasted zucchini and squash warm alongside your favorite main dishes. It’s a delightful side that complements just about anything. Enjoy your meal!
Can I Use Different Vegetables in This Recipe?
Absolutely! Feel free to swap out the zucchini and yellow squash for other vegetables like bell peppers, eggplant, or even asparagus. Just remember to slice them evenly for consistent cooking.
How Should I Store Leftovers?
If you have leftovers, store them in an airtight container in the fridge for up to 3 days. When you’re ready to enjoy them again, you can reheat them in the oven at 350°F (175°C) for about 10-15 minutes or until warmed through. This helps maintain their texture!
Can I Make This Recipe Vegan?
This recipe is already vegan! Just be sure to avoid using any non-vegan garnishes or side dishes. It’s a flavorful and healthy option on its own!
What Can I Serve Alongside Roasted Zucchini and Squash?
These roasted veggies pair wonderfully with grilled chicken, fish, or as a hearty addition to grain bowls or pasta dishes. For a vegetarian option, try serving them with quinoa or alongside a chickpea salad!
