If you want a side dish to impress this is it. Not only is Zucchini tasty, it’s good for you too. It’s low calorie and packed with antioxidants and vitamins B and C. It’s also high in potassium. Even more reasons to make this tantalizing side dish.

This goes perfectly with grilled meats and seafood. Or try a roasted chicken, or baked salmon for a super satisfying meal. You could just have this as your main dish served with a loaf of crusty bread and a side salad and you’ve got a delectable dinner.

Zucchini Gratin Ingredients

  • Zucchini: 6 medium zucchini sliced
  • Mozzarella Cheese: Adds great ooey-ness
  • Parmesan Cheese: This is such a great flavorful cheese
  • Cheddar Cheese: Always a favorite for flavor and color
  • Milk: Any percent of milk will do, skim, 1%, 2% or even whole.
  • Heavy Whipping Cream: Don’t confuse this Frozen Cool whip, that would be bad.
  • Flour: Thickening agent
  • Butter: Everything’s better with butter
  • Salt: Add more or less to taste.
  • Garlic Powder: Trust me, you want garlic in this.

Topping

  • Bread Crumbs: You can use Panko or Regular bread crumbs
  • Parmesan: More flavor and texture, I use gratered.
  • Butter: Holds it all together and helps it taste amazing.

Making 3 Cheese Zucchini Gratin

  1. Sauce: In a medium sauce pan melt the butter and whisk in the flour till thick. Slowly whisk in the milk and heavy cream. Stir in the cheese and mix till melted. Add in the garlic powder and salt.
  2. Layer: Cut the zucchini into 1/4 inch slices. Layer on the bottom of sprayed 2 quart casserole dish. Spoon some of the sauce on top of the first layer. Layer more zucchini and sauce till you’ve used it all ending with sauce last.
  3. Top: For the topping mix together the bread crumbs and parmesan and sprinkle on top. Pour the melted butter on top.
  4. Bake: Bake at 375 degrees for 25-30 min till bubbly and heated through. Broil the top for about 5 min. till golden brown.

Tips and Variations for Cheese Zucchini Gratin

  • Cheese: You can definitely mix up the cheeses to your liking or to work with what you’re serving. From cream cheese, feta, to pepper jack you can get creative with it.
  • Zucchini: Slice your zucchini evenly so that they cook at the same rate. You can use yellow zucchini here as well or a mixture of both.
  • Cream:  You can use half and half if you want to reduce the fat a bit.
  • Spices: Add in different spices for extra zing. Make it Italian with basil, and oregano. Mexican, use cumin, chili powder and paprika. Add spices to your liking
  • Topping: For a fun twist try French Fried Onions on top. They are so yummy.
  • Pre-cook: You can pre-cook your zucchini some to reduce the moisture it’ll give off. I recommend sauteing.

Make Ahead and Store

  • Make Ahead: You can mix this up and freeze for up to 2 months. Thaw overnight in the fridge then bake as directed. You may need to add 5-10 min to make sure it cooks all the way through.
  • Fridge: Keep in a sealed container for up to 3 days in the fridge.
  • Freezer: With so much dairy I don’t recommend freezing cooked casserole. It can separate and be grainy when thawed.

  1. I have never even once thought to do this with zucchini!! OMG! It looks incredible girl. Love 🙂

    PS- I don’t know what the lighting situation in your house is, but I’ve found on the cloudy days here (since we’re in the same place for a week or two longer), if I’m shooting at 1pm on the nose, I can usually get good light.

  2. That looks amazing. I haven’t been able to convince my kids that zucchini is edible yet. Perhaps the cheese will turn them into believers. I’m in NC too, I’m over the rain too. My house is always dark anyway since we have so many trees, but lately I have to turn on every light in the house to see.

  3. I have zucchini coming out of my ears and am ALWAYS looking for a new and unique ways to cook it. This looks amazing! Thank you so much!
