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.
The main ingredient is sliced zucchini. I used about three of them to feed six people, so adjust the number accordingly.
Use full-fat cream cheese for the richest flavor and most nutrients - especially on the keto diet.
You'll also use some shredded cheese. Sharp cheddar adds a contrasting flavor to the mild cream 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.
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.
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.
- 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.
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.
Make the cheese sauce
Next, make the creamy cheese sauce in another saucepan. Melt the cream cheese first. Then, whisk the almond milk and heavy whipping cream into the melted cream cheese.
Add garlic and cheese
Add the garlic powder and shredded cheese to the cheese sauce. Keep stirring the grated cheese until the sauce is smooth and everything is melted.
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.
