Ritz Cracker Zucchini Cheddar Casserole Recipe
Introduction
This Ritz Cracker Zucchini Cheddar Casserole is a comforting, cheesy dish perfect for using fresh summer zucchini. With a crispy Ritz cracker topping and creamy cheddar filling, it’s an easy side that everyone will love.

Ingredients
- 3 cups fresh zucchini, thinly sliced or shredded
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 cup sharp cheddar cheese, shredded (divided)
- 1 cup sour cream or Greek yogurt
- 2 large eggs, beaten
- 3 tablespoons butter, melted (for topping plus extra for greasing)
- 1 1/2 cups Ritz crackers, crushed into fine crumbs
- 1 teaspoon salt (for draining zucchini plus seasoning to taste)
- 1/2 teaspoon black pepper, or to taste
Instructions
- Step 1: Wash and thinly slice or shred the zucchini. Sprinkle with 1 teaspoon salt and let it sit for 10 minutes to draw out excess moisture. Then, gently squeeze the zucchini with a clean kitchen towel or paper towels to remove as much water as possible to avoid a watery casserole.
- Step 2: In a large bowl, combine the drained zucchini, finely chopped onion, minced garlic, sour cream or Greek yogurt, beaten eggs, and half of the shredded cheddar cheese. Season with salt and pepper, then stir well until all ingredients are fully incorporated.
- Step 3: Crush the Ritz crackers into fine crumbs and place them in a small bowl. Add the melted butter and toss until the crumbs are evenly coated, which will create a golden and crispy topping when baked.
- Step 4: Lightly grease a baking dish with butter or non-stick spray. Pour the zucchini mixture into the dish and spread it out evenly. Sprinkle the remaining cheddar cheese on top, then evenly distribute the buttered Ritz cracker crumbs over the entire surface.
- Step 5: Preheat your oven to 350°F (175°C). Bake the casserole for 30 to 40 minutes, or until the top is golden brown, the casserole is bubbling, and it is set firmly. Remove from the oven and let it cool slightly before serving for easier slicing.
Tips & Variations
- For extra flavor, add a pinch of dried thyme or paprika to the zucchini mixture.
- Substitute sharp cheddar with a blend of cheddar and mozzarella for a milder, stretchier texture.
- To keep the casserole gluten-free, use gluten-free crackers in place of Ritz crackers.
- If using Greek yogurt, choose full-fat for the creamiest result.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave until warmed through, or cover loosely with foil and warm in a 350°F (175°C) oven for 10–15 minutes.
