Looking for a light side dish that brings out the best of summer produce with a golden, cheesy crust? Parmesan Baked Yellow Squash is that perfect combination of easy prep, minimal ingredients, and baked perfection that turns humble squash into a table-worthy favorite. This dish is especially ideal when you’re swimming in garden squash or want a quick veggie solution that isn’t steamed or sautéed.

With just a few pantry staples and fresh yellow squash, you’ll create a slightly crispy, Parmesan-kissed layer that delivers satisfying flavor and texture. It’s naturally gluten-free and can be doubled easily for gatherings or potlucks. Serve it alongside grilled meats or as part of a vegetarian plate for a complete, colorful meal.

Preparation Phase & Tools to Use

Before diving into this recipe, let’s talk about the tools that make the process seamless. First, a sharp chef’s knife or mandoline is essential for slicing the yellow squash evenly—this ensures each piece bakes at the same rate and gets the right texture. A baking sheet or casserole dish works well depending on your batch size, but lining it with parchment paper will help prevent sticking and make cleanup a breeze.

You’ll also need a mixing bowl to toss your squash rounds with oil and seasonings, and a microplane or cheese grater to freshly grate the Parmesan for optimal melt and flavor. Lastly, a broiler-safe oven is key—those last few minutes under the broiler help achieve the golden, crispy top layer that makes this dish irresistible.

Ingredients for the Parmesan Baked Yellow Squash

Yellow squash: The star of the dish. Choose firm, medium-sized squash for best texture and sweetness.
Olive oil: Helps coat each slice and encourages browning.
Parmesan cheese: Freshly grated for bold flavor and that perfect crispy topping.
Garlic powder: Adds depth and savory aroma.
Salt and pepper: Essential to enhance and balance the sweetness of the squash.
Fresh herbs (like thyme or parsley): Optional, but great for garnish and added brightness.

How To Make the Parmesan Baked Yellow Squash

Step 1: Prep the Squash

Wash and dry the squash thoroughly. Trim the ends and slice into 1/4-inch thick rounds using a knife or mandoline for even pieces.

Step 2: Season and Toss

In a mixing bowl, toss the squash slices with olive oil, salt, pepper, and garlic powder until evenly coated.

Step 3: Arrange and Sprinkle

Place the slices in a single layer on a parchment-lined baking sheet. Sprinkle each round generously with freshly grated Parmesan.

Step 4: Bake to Golden

Bake in a preheated oven at 400°F (200°C) for about 20 minutes or until the squash is tender. Finish with 2-3 minutes under the broiler to crisp the Parmesan.

Step 5: Serve Hot

Garnish with fresh herbs if desired, and serve immediately while the tops are still golden and crispy.

Serving and Storing Parmesan Baked Yellow Squash

This dish is best served hot straight from the oven, as the cheese is at its crispiest and the squash tender. It pairs beautifully with grilled chicken, steak, or even pasta.

If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. Reheat in a toaster oven or under a broiler for a few minutes to restore some of that crispy topping. Avoid microwaving, as it softens the texture too much.

Frequently Asked Questions

How do I keep the squash from getting soggy?

Slice them evenly, don’t overcrowd the baking sheet, and finish under the broiler to draw out excess moisture.

Can I use zucchini instead?

Yes! Zucchini works just as well in this recipe and can even be mixed with yellow squash for color.

What kind of Parmesan should I use?

Always go for freshly grated Parmesan rather than pre-shredded. It melts and crisps up far better.

Can I make this ahead?

It’s best served fresh, but you can slice and season the squash ahead of time and store it in the fridge until ready to bake.

Can I make it in an air fryer?

Yes, an air fryer works well for a smaller batch. Cook at 375°F for 10-12 minutes, checking for browning.
