Step-by-step preparation of Cheesy Squash, Zucchini, and Corn Casserole
Creating your own cheesy squash, zucchini, and corn casserole can be both fun and rewarding. Let’s break down the preparation process into easy steps that will guide you through every part of the recipe, ensuring you end up with a delicious and satisfying dish.
Gather and prepare your ingredients
Start by gathering all the ingredients you'll need. Here's a quick rundown:
- 4 cups yellow squash
- 4 cups zucchini
- 1 ½ cups chopped onion
- 4 cups chicken broth
- 2 cups cooked corn
- ½ cup mayonnaise
- ½ cup sour cream
- 2 large eggs
- 2 tablespoons melted butter
- 1 teaspoon salt
- ½ teaspoon pepper
- 2 cups shredded sharp cheddar cheese
- 1 ½ cups crushed Ritz crackers
Once you have everything ready, wash and slice the squash and zucchini into ¼-inch thick pieces. This allows them to cook evenly and meld beautifully with the other flavors.
Cook the squash and zucchini mixture
In a large saucepan, combine the squash, zucchini, onion, and chicken broth. If you find that the liquid isn't quite reaching the top of the veggies, feel free to add a little water. Bring the mixture to a boil, then turn the heat down and let it simmer for 6 to 7 minutes. You want to cook until the squash and zucchini are tender. Pro tip: This step not only makes them soft but also enhances their flavors, thus ensuring a rich-tasting casserole. After cooking, be sure to drain the mixture well and stir in the corn.
Preheat the oven and prepare your baking dish
While your veggies are cooling, preheat your oven to 350°F (175°C). Grease a 2-quart baking dish with butter or cooking spray. This step is crucial for preventing sticking; no one wants to wrestle with a casserole that won’t come out in one piece!
Mix the creamy filling
In a large bowl, whisk together the mayonnaise, sour cream, eggs, melted butter, salt, and pepper. Give it a good mix to create a smooth base. Now, fold in 1 ½ cups of the shredded cheese. This will create the creamy texture that blends beautifully with your vegetables.
Combine and layer the casserole
Next, stir the squash mixture into the creamy filling until everything is well combined. To layer your casserole, transfer half of the mixture into the greased baking dish. Sprinkle half of the crushed Ritz crackers on top, followed by the rest of the squash mixture. Finish off with the remaining cracker crumbs and the rest of the cheese. This layering is important for achieving that scrumptious, crispy topping.
Bake until golden and bubbly
Finally, place your casserole in the oven and bake for around 25 minutes. Watch for it to turn golden and bubbly—it’s one of the best sights you’ll see in your kitchen!
Let your cheesy squash, zucchini, and corn casserole cool for a few minutes before serving. Trust me, it’s worth the wait! Enjoy it as a main dish or a delightful side; this casserole is bound to impress anyone at your dinner table.

Variations on Cheesy Squash, Zucchini, and Corn Casserole
Add-ins for Added Flavor

Gluten-Free Version
For those following a gluten-free diet, simply swap out the Ritz crackers for gluten-free breadcrumbs or crushed gluten-free crackers. This small change ensures everyone can enjoy this delightful dish without sacrificing flavor. You can also explore gluten-free mayonnaise options to keep everything within dietary needs. Your guests won’t even notice the difference!
