Summer Squash Gratin

With only a handful of ingredients, this squash casserole come together quickly for a weeknight meal.

My children and husband are trying to kill me.

I’m sure of it.

It’s the only explanation for why they wrinkle their noses and roll their eyes at my attempts to feed them vegetables.

They are just waiting for me to die of frustration.

I won’t give them the satisfaction, though. I’m in it to win it. They will eat their mother-lovin’ veggies and they will like them.

Especially if I cover them in heavy cream and cheese. I actually kept the cheese and cream to a minimum in this recipe – 4 ounces of cheese and a 1/2 cup of cream – totally respectable amounts, right?

I love the slight tang of zucchini, so I paired this with an extra sharp white cheddar. Swiss or Gruyere would be fabulous, too. I also threw in a yellow squash and a potato, just to keep things interesting.

Summer Squash Gratin


1 medium zucchini
1 medium yellow squash
1 medium potato
1/2 cup heavy cream
4 ounces extra sharp white cheddar, grated
salt and pepper, to taste


Preheat the oven to 425 degrees.
Slice the zucchini and yellow squash to between 1/4 and 1/8 inch thick. Slice the potato into paper thin slices. Place all the sliced vegetables into a bowl and toss to mix them up.
Place a single layer of mixed vegetables in the bottom of a 2 quart baking dish. Sprinkle with salt and pepper. Sprinkle on 1/3 of the cheese.
Repeat the layers twice more and pour the heavy cream over the top.
Cover the dish in foil and bake for 25 minutes.
Remove the foil and bake for another 15 minutes.

    Heavy cream, cheese, or even CHOCOLATE will get my meat-loving bf to eat his veggies! Yep, chocolate + zucchini works wonders together ha! But this… oh man… this would be a sure fire way to please him AND use up my garden fresh summer squash. double whammy!

    I have the same problem getting my men to eat veggies. This looks so good, I’m sure I could sneak it past them. Fingers crossed!

    Rock those veggies, girlfriend! If your fam won’t eat ’em… call me! I’ll be over in a New York minute. Umm…or whatever state you live in ๐Ÿ˜‰

    I cannot get my kids to eat veggies lately – I guess I need to start covering them in cream and cheese! Who am I kidding though – I would just end up eating the whole pan myself (and I wouldn’t complain!!)

      That’s what I did. We all ate dinner and then I finished off the pan as I was cleaning up. Whoops. ๐Ÿ˜‰

    This reminds me of a gratin I made recently except I threw pesto into the mix. My parents ate it with only a minor amount of protest.

      Your parents? Hahaha! Are they not veggie fans?

    This is such a great alternative to starchy potatoes au gratin… and perfect for summer!

    Made these tonight using pepper jack cheese and parmesan reggiano because that’s what I had on hand. I used two zucchini fresh from the garden and left out the rest because I did not have any of it. They turned out yummy! Next time I’m going to try adding a bread crumb topping and see how it turns out. Definitely making again.

    I invited a family over for dinner and she brought this dish… OMGoodness… It was amazing, to the point I looked for it and finally had to ask her the exact name! All I can say is I’m planting more zucchini and summer squash next year!
