Ingredients
  

For the Gratin
  • 2 tablespoons Butter Adds richness and flavor; substitute with olive oil for a dairy-free version.
  • 1 medium Onion Provides base flavor and sweetness when sautéed; shallots work well as an alternative.
  • 2 medium Zucchini Main ingredient that adds bulk and nutrition; opt for smaller zucchinis for a more tender texture.
  • 2 medium Yellow Squash Complements zucchini's flavor; can be swapped with more zucchini or other summer squash varieties.
  • 2 cloves Garlic Enhances flavor profile; fresh garlic is preferred, but garlic powder can be used in a pinch.
  • 1 cup Heavy Cream Creates a rich, velvety sauce; for a lighter option, substitute with half-and-half or use coconut cream for a non-dairy choice.
  • 1 cup Parmesan Adds salty, savory notes; grated pecorino or nutritional yeast can be used for a dairy-free alternative.
  • 1 cup Smoked Gouda Provides a smoky depth of flavor; regular gouda or cheddar can be used for a different taste.
Optional Toppings
  • Fresh Herbs Add fresh thyme or basil for an herby boost.
  • Additional Cheese Swap smoked gouda with Swiss or Gruyere for a unique flavor.
