Key Ingredients for Roasted Summer Squash

See recipe card below for full list of measurements, ingredients, and instructions.

Summer Squash

The stars of this recipe! Summer squash (like yellow squash or zucchini) bring a sweet, buttery flavor and gorgeous color to the dish. For best results, look for squash that are firm and free of blemishes. Slice into half-inch rounds or half-moons for even roasting. You can use all yellow squash, all zucchini, or a mix for a vibrant presentation.

Olive Oil

A good drizzle of olive oil ensures your squash roasts up golden and crisp around the edges. Use extra-virgin for the best flavor, or swap for avocado oil if you prefer a milder taste. Avoid using too little—oil helps caramelize the squash.

Garlic

Minced fresh garlic adds a fragrant, savory pop that elevates the simple squash. If you’re sensitive to fresh garlic, try using garlic powder for a subtler flavor, or skip it for an even more basic preparation.

Fresh Herbs

Chopped fresh parsley or thyme adds a burst of color and flavor. You can also try basil, dill, or oregano—whatever’s fresh from your garden or local market. Dried herbs work in a pinch, but fresh really sings here!

Parmesan Cheese (Optional)

A shower of grated Parmesan at the end gives a salty, savory finish. If you’re dairy-free, leave it off or try a sprinkle of nutritional yeast for a cheesy touch without the dairy.

Instructions for Roasted Summer Squash

See recipe card below for full list of measurements, ingredients, and instructions.

Preheat Your Oven

Start by preheating your oven to 425°F (220°C). A hot oven is key for getting those delicious golden edges without overcooking your squash.

Prep the Squash

While the oven heats up, wash and dry your summer squash and zucchini. Cut them into even 1/2-inch slices or half-moons to ensure they roast evenly. Uniform pieces mean every bite is perfectly cooked!

Season Everything

In a large bowl, toss the sliced squash with olive oil, minced garlic, salt, pepper, and chopped herbs. Make sure every piece gets a nice, even coating—this is what builds big flavor as they roast.

Spread on the Baking Sheet

Arrange the squash in a single layer on a large baking sheet. Give each piece a little space—overcrowding leads to steaming instead of roasting. Use two pans if necessary for maximum golden-brown goodness.

Roast to Perfection

Roast in the preheated oven for 20 to 25 minutes, flipping the squash once halfway through. You’ll know they’re ready when they’re tender and golden around the edges. For even more caramelization, broil for 1-2 minutes at the end if you like.

Finish and Serve

If using, sprinkle the hot roasted squash with grated Parmesan and extra herbs. Serve immediately while warm and enjoy that irresistible, fresh-from-the-oven flavor!

Recipe Variations

Make It Vegan

Skip the Parmesan cheese or use a vegan Parmesan substitute or nutritional yeast for a dairy-free, vegan-friendly twist that still delivers a cheesy flavor.

Add a Kick

Like a bit of heat? Toss the squash with a pinch of red pepper flakes or a dash of cayenne before roasting for a spicy, bold bite.

Mediterranean Flair

Add sliced cherry tomatoes and a handful of pitted kalamata olives to the squash before roasting, and finish with crumbled feta and fresh basil for a Mediterranean-inspired side.

Cheesy Crust

For extra crunch, sprinkle the squash with a mix of grated Parmesan and panko breadcrumbs during the last 5 minutes of roasting.

Herb Swap

Experiment with different herbs! Try fresh basil for a sweet, summery note, or rosemary for a rustic, earthy flavor.

Serving Suggestions

Pair your Roasted Summer Squash with grilled chicken, steak, or fish for a balanced meal, or serve alongside quinoa or pasta for a hearty vegetarian plate. It’s also fantastic tossed into salads, folded into omelets, or served atop crusty bread. Garnish with extra herbs and a squeeze of lemon juice for a bright, fresh finish.

Storage and Reheating

Store leftover roasted squash in an airtight container in the refrigerator for up to 4 days. To reheat, simply spread on a baking sheet and warm in a 400°F oven for 5-8 minutes, or microwave in short bursts until heated through. Freezing is not recommended, as the texture can become watery once thawed.
