Ingredients
Instructions
- Pour melted butter into a 1 1/2-quart casserole dish.
- Add sliced yellow squash to the casserole and sprinkle with salt and pepper.
- In a separate bowl, combine beaten egg, mayonnaise, chopped onion, and sugar; mix well.

Tips & Substitutions
For a lighter version, consider using Greek yogurt instead of sour cream. You can also swap the yellow squash with zucchini or a mix of both for added flavor. If you want extra crunch, top with crushed crackers or breadcrumbs before baking. Make sure to slice the squash thinly for even cooking, as thicker slices may require longer baking time.
Serving Suggestions
This Sliced Squash Casserole pairs beautifully with grilled meats or a fresh salad for a complete meal. It can serve as a delightful side dish for family gatherings or potlucks. For a hearty vegetarian option, consider serving it alongside a quinoa salad or with a slice of crusty bread. Don't forget to check out Tiny Cheese Biscuits for a perfect appetizer.
Storage & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in an oven preheated to 350°F (175°C) for about 15-20 minutes until warmed through. You can also microwave individual portions for a quick meal, but the oven method will help retain the casserole's texture.
