This Zucchini and Yellow Squash Au Gratin is a harmonious blend of creamy, cheesy goodness and fresh veggies. The luscious cheddar and Parmesan sauce wraps around the tender zucchini and squash slices, making each bite pure bliss. The golden brown crust on top, kissed with breadcrumbs and garnished with fresh parsley, takes it to the next level!
Ensure you slice the zucchini and squash evenly to promote even cooking.
Customize the cheese by using Gruyère or mozzarella instead of cheddar for different flavor notes.
Add a pinch of nutmeg or some red pepper flakes for extra depth in the sauce.
