Summer is in full force here and with it comes lots of fresh zucchini and yellow squash.  Even if you don’t grow it the season brings such an abundance that the market price drops on it consequently making this dish even more desirable.  This delectable Zucchini Gratin takes about 15 minutes of your devoted time and then it is in the oven for an additional 15-20 minutes making it very doable for a weeknight meal. This recipe will bring out a passion for zucchini and squash that you never knew you had! 

WHAT IS ZUCCHINI

Zucchini is a summer squash.  It is native to central America and Mexico but it is grown throughout the United States during the warm summer months. While you may think of zucchini as a vegetable it is actually a fruit.  Zucchini and yellow squash are low in calories with a low glycemic index. Both squashes are a good source of vitamins A and C, fiber and potassium and they make a great zucchini gratin.

HOW TO MAKE ZUCCHINI GRATIN!

This delectable recipe could not be any easier!  Using an ovenproof skillet melt the butter and add the onion.  Saute until the onion is slightly soft and browned on the edges.  Add the garlic and cook one more minute.  Add cream and simmer until bubbly and slightly thickened.  Slowly stir in Parmesan then add zucchini and yellow squash and cook for a few more minutes.  Sprinkle with Gouda and bake for 15-20 minutes. 

So easy and so delicious. It is amazing what happens to a veggie after you bake it in a bath of cream and cheese.  Oh yeah don’t forget to give credit to the garlic!  As if that isn’t enough there is a blanket of smoked gouda on the top to create the most delectable squash dish ever!

  • 1/2 cup heavy cream
  • 1/4 cup parmesan
  • 1 cup shredded smoked gouda

Instructions

  1. Preheat oven to 450 degrees
  2. Melt butter in oven proof skillet over medium heat. Add onion and cook until the edges start to brown approximately 5 minutes. Add garlic and cook for additional 1 minute.

Notes

The zucchini that I used were on the smaller side. Some of the late summer zucchini I see coming in are much larger. For those I would double the cream and the Parmesan. The large zucchini are sometimes a little tougher and may require additional simmering and/or baking time.

  2. Thanks for the recipe! I had just purchased some yellow squash & zucchini on Sunday, and I am excited to try this! I’ll let you know how it turns out! I am pairing it with meatballs & a spinach/romaine salad for my family this evening.

    Take care!

  3. I am going to try this tomorrow, don’t have time to go to the grocery store to get gouda cheese, I will try it with cheddar and Monterrey jack cheese and see how that turns out. This is a simple recipe and I will probably make it all summer long! Thanks for sharing this!

  6. I make a dish very similar to this but it has sliced tomatoes on top of the squash/zucchini. If you like tomatoes, it’s delicious! Especially home grown tomatoes in the summer!

  7. This was delicious!! We paired it with salmon and it was a winning combo. I will definitely make this again and again over the summer! I didn’t have gouda (though omg, this would be phenomenal with smoked gouda!) so I used fresh parmesan–I actually DID have it on hand–and topped it with sharp cheddar. There were NO leftovers! Thanks so much for a winning recipe!

      • Shoot! You’re so welcome! I have to put this out there too: I’m not opposed to spending an hour cooking (I cook most things from scratch), but I have to say that this recipe was SO EASY and quick to put together! The thing that took the longest was browning the onion, but that time was SO WORTH it for the flavor the caramelized onions added to the dish. I didn’t cook the squash and zucchini in the skillet (not to save time, just because I didn’t want mush). I put half of them in the skillet to coat them with the sauce, and poured that on the rest that I’d already layered in my casserole dish and cooked for 20 minutes. It came out perfect to our tastes. And like I said, NO LEFTOVERS–always a good indication of a GREAT recipe!

  9. I am going to try this tomorrow, way too hot today to have my oven on 450 degrees. I don’t have smoked gouda either, so 1. The store or 2. I will use any other cheese I have on hand. I will revisit this after but wanted to say this Looks like a fun recipe to try. I get my zucchini and summer squash at Costco, never mind what’s growing in my gardens, they’re just about ready now. Another fun recipe I make is the zucchini nacho recipe I found on the internet. The spicy one with roundscut half inch wide. I have been doing Low Carb since Feb. So I am always looking for new recipes. Thank You.

  13. I refer to myself as s food snob. This dish was incredible!! I bought a high quality smoked Gouda which I think is very important. I made this dish for a ladies group pot luck. I thought they were going to lick the casserole clean!! Thank you so very much for elevating a basic, easy to make recipe and making it something truly special!

  14. Made this tonight in my new iron skillet but with half-and-half and cheddar (all I had on hand) and it was delicious! So simple, not mushy, perfect balance of vege and cheese. I’ve been looking for a recipe like this for a long time. Thank you! By the way, I posted it on Insta but wasn’t sure your handle to give you credit (so I used your website).

  15. This recipe sounds fabulous. I have a question – can I assemble it tonight and bake it tomorrow? Will it make it too mushy? Thank you in advance.

    Reply

    • Yes I think it might affect it although I have not tried that. If you try that please let use know how it turned out!

  16. I am so excited to make this tonight only I am adding fresh mushrooms, and tomatoes/bacon bits on top. Thank you for sharing.

    • Sounds delicious! You are most welcome. I am going to try bacon bits on it the next time I cook it! Yummy!!

  17. Want to make this tonight,but don’t have heavy cream right now,have regular milk and canned cream, would one work you think? Or just hold off til grocery day..thank you.

  18. Made this today with a couple of changes. Didn’t have cream or gouda cheese. Used sour cream and a three cheese blend, turned out delicious.

    Reply

  19. Linda mentions a mixture of Sour Cream and a three-cheese-blend, but what proportions would be appropriate? Hope not a dumb question, ha ha!!? Sounds like a fantastic, easy, not time-consuming recipe, Beth Pierce; I typically write most of my own recipes; thanks mucho for sharing this beauty!!!!!???

    • You are most welcome Roxanne. I am hoping Linda responds. I will try to check back a bit later and see if she did.

  20. Hi and thank you, Beth. I’m just starting out, and heading to the supermarket after doing some research.
    I’m working on potion control and live on my own.
    Would you say this recipe provides 2 portions assuming a palm-sized protein and maybe salad paired with it?
    Thanks, Sharon (novice;-)

    Reply

    • Yes I would say that. Please use small zucchini and squash. Some of the summer garden zucchini can grow really big and I need to make some notes on the recipe for these adjustments.

  21. I made this for dinner tonight and the flavor is really good. I don’t think the ingredients are enough for two squash. I had to double the cream and parm and it still didn’t cover the squash. And I cooked them according to the time and the squash was still hard. I would probably boil the squash first and triple or quadruple the cream mixture or cut down on the amount of squash the recipe calls for. I will def be making it again but with my own measurements. Thanks.

    • Hey Robin thanks for the heads up. I am going to make some notes on that recipe this morning as there is a vast difference in the size of zucchini and the ones I used were small. My neighbor bought me some yesterday that were twice that size.

  22. I made this tonight, I only had yellow squash, but it is delicious. I saw an earlier comment, about caramelizing, the onions. I am going to try that, and I also used some fresh jalapeños, for a little kick. It was really good
