- 1/2 cup of mayonnaise
- 2 large eggs, beaten
- 1 cup of crushed buttery crackers (like Ritz)

Step-by-Step Instructions
1. Prepare the Oven
Preheat your oven to 350°F (175°C). This step is essential to ensure even cooking throughout your casserole.
2. Sauté the Vegetables
In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté for about 3-4 minutes until they become translucent. Then, add the sliced yellow squash. Sauté for another 5-7 minutes, stirring occasionally, until the squash is tender but not mushy. Remove from heat.
3. Combine the Mixture
In a mixing bowl, combine the sautéed squash and onions with the beaten eggs, mayonnaise, garlic powder, salt, and pepper. Stir in the grated cheddar cheese until everything is well combined.
4. Add the Cracker Crumbs
Fold in the crushed buttery crackers into the mixture. This will give your casserole a delectable texture and flavor.
5. Prepare to Bake
Transfer the mixture into a greased 9×13 inch baking dish. Spread it evenly, making sure to get into all the corners. Now, let’s work on the topping!
6. Create the Topping
In a separate bowl, combine the additional cracker crumbs with the melted butter. Mix well until the crumbs are evenly coated. Spread this mixture over the top of the casserole for that perfect crunchy layer.
7. Bake the Casserole
Bake in the preheated oven for about 30-35 minutes, or until the top is golden brown and the edges are bubbly. This is where the magic happens as all those delicious flavors meld together!
8. Cool and Serve
Once out of the oven, let the casserole cool for a few minutes before serving. This will allow the flavors to settle and make it easier to dish out.

Helpful Tips
- Variations: Feel free to mix things up! Add diced bell peppers or zucchini to the sautéed vegetables for a twist.
- Cheese Choices: While cheddar is a classic choice, try experimenting with different cheeses like mozzarella or pepper jack for a bit of spice.
- Gluten-Free Option: For a gluten-free version, substitute the crackers with gluten-free breadcrumbs or a gluten-free cracker.
- Fresh Herbs: Sprinkle some fresh herbs like thyme or parsley on top before serving for an added pop of flavor.
Frequently Asked Questions (FAQ)
Can I use frozen squash for this recipe?
While fresh squash gives the best texture and flavor, you can use frozen squash in a pinch. Just make sure to thaw and drain any excess water before cooking.
What if I don’t have mayonnaise?
If you’re out of mayonnaise, you can substitute it with Greek yogurt or sour cream. This will still provide the creaminess needed for the casserole.
How can I make this casserole ahead of time?
You can prepare the casserole up to the point of baking and cover it tightly. Store it in the fridge overnight, then bake it when you’re ready. It may take a few extra minutes to cook from chilled.
Is this recipe suitable for vegetarians?
Absolutely! This casserole is vegetarian-friendly, making it a great option for Meatless Mondays or any gathering where you want to accommodate different dietary preferences.
Can I make this dish creamier?
Certainly! For a creamier texture, try adding a little cream cheese or sour cream into the mixture. Just blend it in with the other ingredients until smooth.
