How can you change up this zucchini gratin?
There are many ways to change up this recipe. To start, you can add more vegetables to the zucchini. For a nice pop of color and flavor, add in some jarred sliced roasted red peppers; diced asparagus is another option. Any type of green works well, also. Stir in some thinly sliced spinach or kale when you add the zucchini. Just make sure to de-stem the kale before slicing it.
In addition to the Parmesan cheese, you can add other types along with it. Try shredded mozzarella, Gruyère, or jack cheese, and stir that in when you add the Parmesan. For a lighter touch, add crumbled feta or goat cheese.
Changing up the spices is another way to diversify the flavor. For a more Mediterranean slant, try using za'atar. It's a blend of spices that offers a hint of citrus along with a nutty, savory flavor. Fresh rosemary or thyme also work well in this recipe.
What dishes pair well with zucchini gratin?
