Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash is key for great flavor. If you’re out of fresh squash, you can use zucchini for a similar taste and texture!
Onion: A medium onion adds a nice depth of flavor. If you prefer a milder taste, go for green onions or shallots as a substitute.
Cheddar Cheese: Sharp cheddar gives a lovely zing to the casserole. If you want something milder or creamier, try using Monterey Jack or Colby cheese.
Sour Cream & Mayonnaise: Together, they create a creamy base. You can substitute Greek yogurt for a healthier twist without giving up creaminess.
Ritz Cracker Crumbs: These add a crunchy topping. If you’re gluten-free, use crushed gluten-free crackers or even panko breadcrumbs for a nice crunch!
How Do I Cook the Squash Perfectly?
Cooking the squash properly ensures your casserole won’t be watery. The goal is to tenderize it without losing moisture. Here’s how:
- Boil the sliced squash in salted water for just 5 minutes. This softens them.
- After boiling, drain the squash well and use paper towels to pat them dry, soaking up any leftover moisture.
- This will help your casserole stay creamy and flavorful, not soggy!

Step-by-Step Instructions:

Start by preheating your oven to 350°F (175°C) and greasing a 9×13 inch baking dish. This will help your casserole come out easily after baking.

6. Add the Topping:
Sprinkle the buttered cracker crumbs evenly over the squash mixture in the baking dish.
7. Bake Your Casserole:
Slide the casserole into your preheated oven and bake for 30-35 minutes. You’ll know it’s done when the top is golden brown and the casserole is bubbling around the edges.
