This roasted summer squash transforms humble zucchini and yellow squash into a caramelized, herb-infused side dish that will make you forget you're eating vegetables. The high-heat roasting brings out natural sweetness while garlic and herbs add aromatic depth to these summer garden favorites.
I discovered this recipe years ago when my garden produced an overwhelming amount of summer squash. Now it's our go-to method that turns even the most abundant harvest into a dish everyone requests.
Ingredients
- Fresh zucchini and yellow squash: Look for firm ones with bright, unblemished skin for best flavor
- Extra virgin olive oil: Provides rich flavor and helps achieve golden caramelization
- Fresh garlic cloves: Add aromatic punch that mellows beautifully when roasted
- Fresh herbs like basil or thyme: Bring brightness and complexity
- Kosher salt: Enhances the natural flavors without overwhelming
- Black pepper: Adds gentle heat and depth
Step-by-Step Instructions
- Prepare the oven:
- Heat your oven to 425°F and line a baking sheet with parchment paper. The high temperature is crucial for developing caramelization without making the squash soggy.
- Slice the squash:
- Cut zucchini and yellow squash into even half-inch thick pieces. Uniform thickness ensures they cook at the same rate, preventing some pieces from burning while others remain undercooked.
- Season thoroughly:
- Combine the sliced squash in a large bowl with olive oil, minced garlic, salt, and pepper. Toss everything well to ensure each piece is evenly coated with oil and seasonings for maximum flavor development.
- Add fresh herbs:
- Gently mix in your choice of fresh herbs. Keeping this step separate prevents the delicate herbs from getting crushed during the initial tossing.
- Arrange and roast:
- Spread the seasoned squash pieces in a single layer on your prepared baking sheet. Avoid overcrowding which can cause steaming instead of roasting. Roast for 20-25 minutes until golden brown, flipping halfway through for even caramelization.

The minced garlic is my secret weapon in this recipe. When it roasts alongside the squash, it develops a sweet, nutty flavor that completely transforms from its raw state. My family now requests extra garlic cloves scattered throughout the pan just for snacking.
Perfect Pairings
This versatile side dish complements nearly any protein. Try serving alongside grilled chicken, roasted salmon, or even with eggs for a savory breakfast. The clean, bright flavors of the roasted squash provide a wonderful counterpoint to richer main dishes, creating balanced meals without much effort.
Seasonal Variations
While summer squash is the star here, this same technique works beautifully with other vegetables throughout the year. In fall, try butternut or acorn squash with sage. Winter brings opportunities for roasted root vegetables like carrots and parsnips. Spring asparagus roasts beautifully with lemon zest and thyme. The basic method remains the same just adjust cooking times for denser vegetables.
Leftovers Transformation
Transform leftover roasted squash into something completely new. Blend it into creamy soups, add to pasta dishes, fold into scrambled eggs, or pulse in a food processor with chickpeas for a unique hummus variation. The concentrated roasted flavor adds depth to countless dishes, making intentional leftovers a smart cooking strategy.

The roasted summer squash quickly became a family favorite. With its vibrant flavor and ease of preparation, it's bound to become a staple in your kitchen too!
