Why you'll love it

Are you craving something cheesy and smothered in a thick and creamy sauce? If you are, then this recipe for scalloped zucchini is for you!

This is one of my best recipes yet because every single ingredient is cooked perfectly, and it's easy to replicate.

Scalloped potatoes are a favorite side dish of kids and adults alike, but they are not good on the keto diet. So, I made my own cheese sauce and replaced the potatoes with zucchini. The result is fantastic!

This cheesy scalloped zucchini recipe tastes amazing with any main dish you serve it with. I'll give you some ideas about what to serve with this cheesy veggie just a bit further below.

Keep reading, and I'll share some important tips so your side dish comes out perfectly the first time.

Ingredients

ingredients for the scalloped zucchini recipe.

Your scalloped zucchini will taste better when you use fresh ingredients. In fact, this is a wonderful way to use garden zucchini if you have extra.

Here's a bit more information about what I used in my au gratin dish.

Zucchini

The main ingredient is sliced zucchini. I used about three of them to feed six people, so adjust the number accordingly.

Cream cheese

Use full-fat cream cheese for the richest flavor and most nutrients - especially on the keto diet.

Cheddar cheese

You'll also use some shredded cheese. Sharp cheddar adds a contrasting flavor to the mild cream cheese.

Parmesan cheese

You only need a little bit of grated parmesan cheese. It rounds out the flavor in the cheese sauce.

Heavy whipping cream

For the deepest and richest flavors, use full-fat heavy cream. Half and half can work too, but it will affect the flavor.

Almond milk

Always use unsweetened plain almond milk when you make an au gratin recipe. You don't want the sugar from the sweetened versions, and the vanilla will be too strong if you use vanilla almond milk.

Garlic powder

A little bit of garlic powder enhances the flavors in this cheesy dish.

Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.

Tips

  • Grate cheese at home. Shredded cheddar cheese from the store contains hidden carbs and anti-caking agents.
  • Use a mandolin slicer. Ensure the zucchini slices are all the same, so they cook at the same rate.
  • Cook in a cast-iron skillet. You'll be cooking this on the stove and then baking it in the oven, so use a cast-iron skillet that can be used in both.

Instructions

Making scalloped zucchini could not be easier! Here are some photos and additional tips that show you just how simple this cheesy side dish is to make.

Slice and saute the zucchini

First, slice the zucchini, then season all the slices with salt and pepper. Then, saute them in your skillet over medium-high heat until they become tender.

Cover zucchini and bake

Add the zucchini and completely cover it in the cheese sauce. Place it in the oven and bake until it is golden brown.

That's it! Serve warm.

️ Serving suggestions

This cheesy scalloped zucchini is a mild side dish that complements just about any kind of main dish you make. Serve it with your turkey breast at Thanksgiving.

It is also a delicious side dish with roasted chicken. In fact, it has lots of similar spices and flavors.

My favorite way to eat keto zucchini gratin is on the side with some tasty keto beef tenderloin. It's made with an incredible garlic butter that resembles the garlic and butter in this side.

Variations

Scalloped zucchini is a fantastic way to use fresh zucchini, and there are a few different ways you can change this recipe. If you make any changes, let me know in the comments.

If you don't have a cast-iron skillet, you can use a casserole dish or baking dish. Just make sure you bake it until the zucchini is golden brown.

Add some yellow squash to the mix, or use the yellow squash instead of zucchini.

You can also sprinkle some onion powder in with the garlic powder.

FAQs

Here are some questions people often ask about making scalloped zucchini. If you don't see your question in this list, please leave it in the comments.

Does scalloped zucchini taste like scalloped potatoes?

There is going to be a difference in the texture of zucchini versus potatoes. The cheese sauce is almost identical, though.

Can I use summer squash instead of fresh zucchini in this au gratin recipe?

Yes, summer squash is a perfect replacement for zucchini in this au gratin recipe.

Are au gratin potatoes keto-friendly?

No, potatoes are not a keto-friendly food. Replace potatoes with either zucchini, squash, or cauliflower.

What are the best fresh herbs to add on top of scalloped zucchini?

I like to add fresh parsley on top. Not only does it add a pop of color, but it has a fresh and sweet flavor too.

What do I do if I think there is too much liquid?

Continue to cook at low heat until it cooks down. You can also use a slotted spoon to serve the zucchini if you aren't a fan of the cream mixture.

    This dish is phenomenol (she says as she licked her lips). It paired perfectly with the air fried chicken. So thankful to have left overs a few more times this week.

    HI, Lisa! I love your recipes and this one looks fabulous - I love everything about it! I subscribe to your saved recipes. However, when I click on SAVE Recipe, it takes me to logging in on your site, and if the payment for the month hasn't been made yet, I can't save the recipe. Can I change how my acct is paid to make it on the first of the month?
