Summer Squash Casserole with Tomatoes and Mozzarella

Our good-gardener, neighbor Mike brought us some beautiful pattypan squash from his garden, and also a package of heirloom tomatoes that he had sun-dried and put up from another year’s bounty.  I’m so glad I live near a generous person with a green thumb!  Mike suggested cooking the squash in a tomato sauce with some cheese, in the style of Eggplant Parmesan.  I took his advice and came up with this squash casserole.

This recipe is very adaptable.  I added sausage, since I had some that needed cooking, but this would work fine as a vegetarian recipe without the sausage.

Pattypan Squash

Instead of pattypan squash, you could likely use any summer squash.

Pattypan squash are the scallop-edged summer squash that look like flying saucers.  These are the white variety, but they also may be green or yellow.  Despite their odd shape, they are easy to slice up and cook, like the other varieties of summer squash.


  • 1/2 sweet onion, chopped
  • 1 tablespoon olive oil
  • 1/2 pound sausage – optional (I used bulk breakfast sausage, but sweet Italian sausages – without casing – would also be good)
  • 16 ounces crushed tomatoes
  • 2 pinches Ratatouille Seasoning, or herbs of choice
  • ~1/4 teaspoon crushed red pepper flakes
  • Kosher salt and freshly ground black pepper, to taste
  • 2 pattypan squash
  • ~1/3 cup julienned sun-dried tomatoes
  • 8 ounces fresh mozzarella cheese
  • ~1/2 cup freshly grated Parmesan cheese

In a large skillet or saute pan, heat the olive oil over medium-high heat.  Add the onion and cook until softened.  Add the sausage (if using); cook while breaking up the meat into small pieces with a wooden spoon until browned.  Pour off the excess fat from the pan. Add crushed tomatoes, herbs, and red pepper flakes.  Allow to simmer on low heat for 5-10 minutes.  Season with salt and pepper to taste.

Remove the stem ends from the squash, and slice in half (from stem end to bud).  Place sliced side down, then cut into ~3/8-inch slices.

Preheat oven to 350F.  Lightly oil a baking dish, then spread a scant layer of tomato sauce in the bottom of the dish.  Make one layer of sliced squash across the dish, using 1/2 of the squash slices.  Distribute the julienned sun-dried tomato on top of the squash layer.  Chop up the mozzarella cheese, and add 1/2 of the cheese.  Top the cheese with the remaining slices of squash.  Add the remaining tomato sauce, spreading it evenly across the squash.  Top with remaining mozzarella cheese and Parmesan cheese.

Cover tightly with foil, and bake for 60-70 minutes.  Uncover and check for doneness – it is done when the squash is tender and the sauce is bubbly.  If needed, cook for ~ 10 additional minutes to reduce liquid and/or brown the cheese topping.

One of our favorite musicians passed this week, Doc Watson. A wonderful guitarist, singer and historian, Doc brought the music of his North Carolina mountains to the world. He will be sorely missed. Here’s a few favorites. First off, Southbound his 1966 release with his son, Merle. Includes “Walk On Boy” and “Tennessee Stud”. Amazing stuff.

Secondly, Doc played all sorts of music, from fiddle tunes to jazz, but I love his blues. Here’s a good selection called Trouble in Mind. From “Little Sadie” to “Deep River Blues” (my all time favorite), Watson knew his way around the blues. Essential.

    Ummm….yes, please? This looks totally awesome as a main dish with some broccoli or something alongside. The squash/sausage/tomato combo sounds fantastic. I have a feeling this is going to go on my to-make-immediately list!

    Thanks, Carrie! I was mainly trying to get rid of some sausage (we get a LOT of sausage in our CSA allotment), but I ended up being really happy with the way it came out. We will make this again!

  3. wow that looks great and with other summer squashes coming in abundantly soon, you could adapt your neighbor’s zucchini to serve this same purpose!

    I am assuming this could be frozen… for eating through the winter ? 🙂

      Brooke, I have to say I have no idea how well it would freeze. I suspect it would be fine frozen, but until I get a bigger freezer I will never know. Ours is always overflowing! If anyone else has experience freezing this type of thing, please help us out with a comment!

    Very good! I used crumbled meat substitute, added garden green beans, and put together a medley of garden herbs for seasoning. I think it would have been ready in 45 minutes based on how tender the squash was at 60 minutes. Thanks for sharing your recipe!

    I have made this recipe twice now in the UK, using pattypans that my lovely neighbour grew. My fiancé is vegetarian so we didn’t use meat sausage, but added chopped up Tofurky Italian sausages about 5-10 minutes before the end of cooking. A gorgeous recipe, thank you so much for sharing it!
