How long to roast squash
Squash and zucchini are tender, quick cooking vegetables that don't need as much time in the oven as heartier veggies like brussels sprouts or broccoli.
Thick, ½ inch disks only need about 15 to 17 minutes in a 400 degree Fahrenheit oven.
How to prevent soggy zucchini
Zucchini and squash are high water content vegetables, made of about 90 to 95% water. Unless you're dehydrating your veggies, they're not going to ever turn out crispy or crunchy. However, there are a few ways to help prevent your zucchini from getting soggy in the oven.
- Take care not to overcook your zucchini and squash in the oven. Overcooked squash will turn out soggy and mushy.
- Slice your squash into thick, ½ inch slices. Thinner squash cooks faster and is easier to overcook.
- Your veggies will begin to 'sweat' and release water after being sliced. Just before tossing in oil, pat your zucchini and squash dry on both sides with a paper towel or kitchen towel.
- Optionally, roast your veggies on an oven-safe cooling rack, like this one (Amazon - Stainless steel cooling rack). Line a baking sheet with foil, then place the oven safe cooling rack on top. This helps air circulate around your veggies and excess moisture to drip down to the baking sheet below.
Do I need to peel zucchini?
You may be wondering, do I need to peel my zucchini before baking? No, the skin of zucchini is perfectly edible and there's no need to peel it off before baking.
The skin of your zucchini also contains extra nutrients that you'd be missing out on by peeling the skin off. Not to mention peeling takes extra prep time that's unnecessary.
Leftovers and storage
Roasted zucchini and squash is best served immediately after roasting, and will soften and lose its texture over time.
Leftovers will keep for 3 to 4 days in a tightly sealed container in the refrigerator. I do not recommend freezing roasted zucchini or squash, as it will get significantly softer and mushier once frozen and thawed.
Roasted Zucchini and Squash
- 1.5 tablespoons olive oil
- 2 small zucchini
- 2 small yellow squash
- 1.5 teaspoons Italian seasoning
- 1 teaspoon garlic powder
- ½ teaspoon salt
- ¼ teaspoon pepper
- ½ cup grated parmesan cheese
- Preheat oven to 400 degrees Fahrenheit. Line a baking sheet with parchment paper and set aside.
- Slice zucchini and yellow squash into thick ½ inch disks and pat dry with a paper towel. Set aside.
- In a bowl, combine olive oil, Italian seasoning, garlic powder, salt, and pepper. Add zucchini and yellow squash disks and toss to coat.
- Pour zucchini and squash onto parchment lined baking sheet and spread into a single layer. Sprinkle tops of zucchini and squash with parmesan cheese.
- Bake for about 15-17 minutes, or until cooked through to your liking.
- I highly recommend using freshly grated parmesan cheese. Pre-grated parmesan cheese (or parmesan cheese sold in a green cylinder) often contains anti-clumping powder which when melted, can be grainy.
- Larger or thicker zucchini and squash may need a few more minutes to cook through. Test for doneness by piercing through with a fork in the center.
