This low carb cheesy zucchini gratin is a healthier alternative to potato gratin. It’s a tasty low carb and gluten-free side dish the family will enjoy.
A simple keto zucchini dish that is easy to make and makes a great dinner dish with minimum fuss. You can bake this ahead then re-heat when you are ready to eat. I find it hearty enough to eat by itself with a green side salad.

What is in this Zucchini Gratin?
I used a mixture of green and yellow squash zucchini for a colorful dish. I find the yellow zucchini adds a touch of sweetness to It. If you wanted a sweet side dish only use the yellow zucchini.
For the creamy cheese sauce, I used mascarpone instead of heavy cream for a thicker sauce. You could use cream cheese for an extra creamy dish.
I kept the seasoning very basic but adding herbs such as thyme or a dash of nutmeg would be a great addition to this dish. Whatever you used to use in your potato gratin, throw it in this gratin too!
Ingredients
- Zucchini - we used a mixture of yellow and green zucchini as the yellow zucchini gives an additional sweetness to the dish. This is a great use of summer squash.
- Mascarpone cheese - cream cheese could be substituted.
- Parmesan cheese - freshly grated and nothing from a tub.
- Cheddar cheese - we use a strong British Cheddar cheese.
- Olive oil - for a richer dish, butter could be used to cook the vegetables.
How to make Zucchini Gratin
A simple low carb zucchini recipe that makes a great side dish anytime of the year.
Saute onion and garlic.
Add thinly sliced zucchini and cook until golden on both sides.
Mix mascarpone and egg.
Add the rest of the cheeses.
Place cooked vegetables in a casserole dish.
Top with cheese mixture and bake.
Recipe Tips
Ensure that the zucchini slices are thin and even for this zucchini au gratin dish. Mine were sliced about a quarter of an inch and held their shape well without becoming too limp and watery.
Try to use fresh Parmesan cheese if you can get it for a strong taste. You could use other cheese such as Gruyere, Fontina or Monterey Jack for other flavours.
This dish could be turned into a cheesy zucchini bake if you spiralise the zucchini instead of slicing it.
What cheese goes with zucchini?
Several types of cheese pair well with zucchini, and the choice depends on personal preferences and the specific dish you're making. Here are some popular cheese options that complement zucchini nicely:
- Parmesan: Parmesan cheese adds a salty, nutty flavor to zucchini dishes, making it a classic and delicious choice. Grated or shaved Parmesan works well on roasted zucchini, in pasta dishes, or on top of zucchini gratins.
- Feta: Feta cheese's tangy and salty taste pairs nicely with zucchini, especially in Mediterranean-style recipes. Try it in salads, stuffed zucchini, or mixed with roasted zucchini and cherry tomatoes.
- Goat Cheese: Goat cheese's creamy and slightly tangy flavor contrasts well with the mild taste of zucchini. Use it in stuffed zucchini, on zucchini pizzas, or in creamy pasta dishes.
- Gouda: Smoked Gouda, in particular, complements zucchini with its rich and slightly sweet taste. It's excellent in casseroles, quiches, or melted on top of grilled zucchini.
- Mozzarella: Mozzarella cheese adds a gooey, melty texture to zucchini dishes. It's a fantastic choice for zucchini lasagna, stuffed zucchini boats, or simple zucchini and tomato bakes.
- Ricotta: Ricotta cheese's creamy and mild flavor works well in zucchini-based dishes like lasagna, stuffed shells, or savory zucchini tarts.
- Cheddar: Sharp cheddar cheese can add a robust flavor to zucchini dishes. Use it in zucchini and cheddar muffins, cheesy zucchini gratin, or zucchini and cheddar fritters.
- Blue Cheese: For those who enjoy strong flavors, blue cheese can be an interesting addition to zucchini recipes. It pairs well in salads, stuffed zucchini, or as a topping for grilled zucchini.
Storage
Any leftovers should be stored in the fridge, in an air tight container. Reheat in the oven or microwave. This gratin should last up to 3 to 4 days in the fridge.

Made this tonight to go with meatloaf. It was so good! I added mushrooms with the onions, and I used cream cheese as I didn't have any mascarpone. Also I halved all the ingredients (except the egg) as it was for just two of us. Very low carb, very yummy.

Glad you enjoyed it and the swap of cream cheese is a great idea. I'd adding mushrooms to this the next time I bake it too!

do you think this would work for Rutabaga
Reply
Angela Coleby
A great idea and yes. But the rutabaga might take longer to cook as it's not as soft as zucchini. I'd parboil it first before adding to a gratin. Let us know how it works!

Is this something you can make ahead of time and if so how long can you keep it in the frig before cooking?
Reply
Angela Coleby
You could make this ahead of time and it should be okay in the fridge for about 4 hours before cooking.

Love this dish! So yummy and lots of compliments. Has anyone tried making a day or two ahead of time?

THIS IS DELICIOUS!!! I usually use cream and the mascarpone/egg/cheese mixture was a delicious, decadent change. I used a cheddar/gouda cheese blend instead of just cheddar, and omitted the mozzarella. I will definitely be making again!

Angela Coleby
Delighted you enjoyed it! I love the cheese blend you used too!

If you use heavy cream or cream cheese to make it cheesier what do you omit? Also how much of this do you use if you were to add the heavy cream or cream cheese? Do you add it with the regular recipe?
Reply
Angela Coleby
I would omit the mascarpone but keep the measurements the same for the swap.

Adapted this, left out the onion but replaced with two leaks cut to same width as courgette / zucchini and replaced cheddar with Gouda, added two teaspoons of English mustard. Worked brilliantly as enhanced the tanginess of the sauce.
