Let’s dive into everything you need to know about making the best squash casserole.
Here’s what you’ll need:
For the Squash
- 3 tablespoons unsalted butter
- 2 pounds yellow squash, ends trimmed and sliced into ¼-1/3 inch rounds
- 1 medium onion, chopped (about 1 cup)
- Salt and ground black pepper to taste
For the Filling
- 2 large eggs
- ½ cup cream
- ½ cup sour cream
- ¼ cup mayonnaise
- 1 cup shredded cheddar cheese
- ½ teaspoon salt
- ¼ teaspoon garlic powder
- ¼ teaspoon ground paprika
- Ground black pepper to taste
For the Topping
- ½ cup shredded cheddar cheese
- 3 tablespoons unsalted butter, melted
- 1 sleeve buttery crackers, crushed
1. Prep Your Dish
Before you begin, grease a 9×13-inch casserole dish. This ensures easy serving and cleanup later.
2. Cook the Squash
- Melt the butter in a large skillet over medium heat.
- Add the sliced squash and chopped onion, seasoning with salt and pepper.
- Cook, stirring occasionally, for 5-10 minutes until the squash is tender and the onion turns translucent.
- Transfer the mixture to a colander and let it drain for 5 minutes. Blot with paper towels to remove excess moisture.
3. Prepare the Filling
- While the squash is draining, whisk together the eggs, cream, sour cream, mayonnaise, shredded cheddar, salt, garlic powder, paprika, and black pepper in a large bowl.
- Gently fold in the drained squash mixture, ensuring all vegetables are evenly coated.
4. Assemble the Casserole
- Spread the squash filling evenly in the prepared casserole dish.
- Sprinkle the remaining shredded cheddar cheese over the top.
- In a separate bowl, mix the melted butter with the crushed buttery crackers, then evenly distribute this topping over the casserole.
5. Bake
- Preheat the oven to 350°F.
- Bake for 20-30 minutes, or until the edges are bubbly, the topping is golden brown, and the casserole only slightly jiggles when moved.
- Let it cool for 5 minutes before serving.
- Drain Well: Excess moisture can make the casserole soggy, so be sure to let the squash drain thoroughly.
- Use Fresh Squash: While frozen squash can work in a pinch, fresh squash gives the best texture.
- Experiment with Cheese: Try using a mix of cheddar, Gruyère, or Monterey Jack for added depth of flavor.
- Make it Gluten-Free: Swap the crackers for gluten-free breadcrumbs or crushed gluten-free crackers.
- Add Protein: Cooked bacon or shredded rotisserie chicken can be mixed into the filling for a heartier dish.

Can I Make This Ahead of Time?

What Can I Use Instead of Crackers for the Topping?
Panko breadcrumbs, crushed cornflakes, or even crushed Ritz crackers work well.
