Summer is winding down but for people who have vegetable gardens or get CSA vegetable deliveries, summer squash keeps showing up far into the fall. And that’s fine with me because so many of my favorite zucchini recipes are cooked in the oven. And it’s prime roasted zucchini season, so today I’m reminding you about this Roasted Summer Squash with Garlic and Parmesan for my Friday Favorites  pick!

For this recipe, the addition of garlic (and of course Parmesan) really makes this  a spectacular way to cook zucchini! If you haven’t tried roasted garlic, you’re going to love the way that roasting makes the garlic sweet and tender, and this recipe is all about the roasted garlic!

And my niece Kara and I thought the addition of coarsely-grated Parmesan could only improve the recipe, and the roasted summer squash was definitely amazing with the garlic and parmesan.

Kara and I both decided we’d double the amount of garlic the next time we made it, so I’ll give you that option in the updated recipe. We used pre-peeled garlic cloves that came in a package, which made this quick to get into the oven and covering the baking sheet with foil made it easy to clean up. I seriously hope you’ll try this tasty idea if you’re still getting summer squash or buying them at the Farmers Market!

How to Make Roasted Summer Squash with Garlic and Parmesan:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

  1. Preheat oven to 450F/230C. Cover a large baking sheet with foil.
  2. Wash the summer squash, cut off the ends, cut in half lengthwise (or not if your squash is small) and cut into slices about 3/4 inch thick.
  3. Peel garlic if needed, and cut some of the bigger cloves in half. (Next time I’d use at least double this amount of garlic!)
  4. Toss squash and garlic with the olive oil and Italian Herb Blend (affiliate link).
  5. Cover a large baking sheet with foil and spread the squash and garlic out on the baking sheet.
  6. Roast the squash and garlic about 20 minutes, or until it’s barely starting to soften and look cooked.
  7. Then sprinkle the coarsely grated Parmesan over the top of the squash pieces, put the baking sheet back into the oven, and cook 5-10 minutes more, or until cheese is all melted and starting to slightly brown.
  8. Season to taste with a little salt and some freshly-ground black pepper and serve hot, and be sure to peel off all the cheese that runs down and melts on the foil!
  9. I bet if you have kids they’ll love  eating that melted cheese the covers the squash, even if they aren’t big zucchini fans!

Roasted Summer Squash with Garlic and Parmesan

Prep Time 10 minutes
Cook Time 25 minutes
Total Time 35 minutes

Roasted Summer Squash with Garlic and Parmesan was one of the first zucchini recipes on Kalyn's Kitchen, and when we updated the photos we had the great idea of adding Parmesan Cheese! And you'll love making this roasted summer squash when the weather is getting cooler but you still have zucchini!

Ingredients

  • 4 medium or 8 small zucchini or yellow summer squash (see notes)
  • 10 large garlic cloves, peeled (We used peeled garlic which came in a package, which was fine for this. Use more or less garlic to taste.))
  • 2 T olive oil
  • 1 tsp. Italian Herb Blend
  • 3/4 cup coarsely-grated or freshly-grated Parmesan cheese (more or less to taste)
  • salt and fresh-ground black pepper to taste

Instructions

  1. Preheat the oven to 450F/230C. Cover a large baking sheet with foil.
  2. Wash the squash, cut off both ends, and cut each piece of squash in half lengthwise (or not if your squash is small.) Cut the squash into slices about 3/4 inch thick.
  3. Peel garlic if needed, and cut some of the bigger cloves in half. (Next time I'd definitely use the larger amount of garlic!)
  4. Toss squash and garlic with all the olive oil and then with the Italian Herb Blend (affiliate link), making sure all the squash pieces are lightly coated with oil.
  5. Spread the squash and garlic out on the baking sheet, making sure all the squash pieces are laying flat and the squash pieces are not touching each other more than necessary.
  6. Roast the squash and garlic pieces about 20 minutes, or until the squash is barely starting to soften and look cooked.
  7. Then sprinkle desired amount of coarsely grated Parmesan over the top of the squash pieces. Put the baking sheet back into the oven, and cook 5-10 minutes more, or until cheese is all melted and starting to slightly brown.
  8. Serve hot, and be sure to eat the melted cheese that drips down on to the foil.

Notes

Use a combination of green and yellow squash for a more colorful dish if you have both types. Any type of dried Italian Herb Blend (affiliate link) will work for this recipe.
