Ingredients

• ¼ cup unsalted butter
• 1 cup sweet onion, peeled and diced
• 1 clove garlic, minced
• 4 medium zucchini, sliced into ¼-inch thick rounds
• 2 teaspoons salt
• ½ teaspoon black pepper
• ¼ teaspoon ground nutmeg
• 2 heaping tablespoons all-purpose flour
• ¾ cup warm milk
• ¾ cup sharp cheddar cheese, shredded (divided)
• 1 cup Ritz crackers (or other buttery crackers)
• 2 tablespoons unsalted butter, melted

How To Make Cheesy Zucchini Gratin

Step 1: Prepare Your Ingredients

Begin by gathering all your ingredients. Make sure to wash the zucchini properly and slice it into ¼-inch thick rounds for even cooking. Dicing the onions small will help them caramelize properly in the butter.

Step 2: Sauté the Onions and Garlic

In a large skillet, melt ¼ cup of unsalted butter over medium heat. Once melted, add the diced sweet onion and cook until translucent, about 5 minutes. Stir in the minced garlic and sauté for another minute until fragrant.

Step 3: Add Zucchini and Seasonings

Add the sliced zucchini to the skillet. Season with 2 teaspoons of salt, ½ teaspoon of black pepper, and ¼ teaspoon of ground nutmeg. Cook for about 5–7 minutes, stirring occasionally until the zucchini is tender but not falling apart.

Step 4: Create the Roux

Sprinkle 2 heaping tablespoons of all-purpose flour over the zucchini mixture in the skillet. Stir well to combine, allowing the flour to cook for about 1 minute, which will help thicken your sauce.

Step 5: Make the Cheese Sauce

Slowly pour in the ¾ cup of warm milk while constantly stirring to avoid lumps. Cook the mixture for an additional 2-3 minutes until it thickens slightly. Remove from heat and then stir in ½ cup of the shredded sharp cheddar cheese until melted and smooth.

Step 6: Assemble the Gratin

Preheat your oven to 350°F (175°C). Pour the cheesy zucchini mixture into a greased 9×9 inch baking dish, spreading it evenly.

Step 7: Prepare the Topping

In a separate bowl, combine the remaining ¼ cup of shredded sharp cheddar cheese with 1 cup of crushed Ritz crackers and 2 tablespoons of melted unsalted butter. Mix until the crackers are well coated. Sprinkle this mixture evenly over the zucchini cheese mixture.

Step 8: Bake the Gratin

Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the top is golden brown and bubbly.

Expert Tips

• For extra flavor, consider adding a pinch of red pepper flakes when sautéing the onions and garlic.
• If the zucchini releases too much water while cooking, you can drain it before adding the cheese sauce to keep the gratin from being soggy.
• Try using a blend of cheeses for a more complex flavor. Gruyère or mozzarella can complement the cheddar beautifully.
• Can also add herbs like thyme or basil for a fresh twist—just sprinkle them in when adding the zucchini.

Variations and Customizations

• Swap out zucchini for yellow squash or a mix of both for added color and taste.
• Incorporate other vegetables such as mushrooms or spinach for a more diverse flavor profile.
• Make it a heartier dish by adding cooked ground turkey or chicken to the vegetable mixture before baking.
• For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend and use gluten-free crackers.

How to Store Leftovers

Allow any leftovers to cool completely, then transfer them to an airtight container. Store in the refrigerator for up to 3 days. To reheat, simply place in a preheated oven at 350°F (175°C) for about 15 minutes, or until heated through. You can also microwave individual portions; just be sure to cover the dish to retain moisture.
