Ingredients
Vegetables
- 2 pounds yellow squash, trimmed and sliced into ¼ inch slices
- ½ large sweet onion, thinly sliced
Seasonings & Dairy
- 1 teaspoon salt, divided
- ¼ teaspoon black pepper
- 1 large egg
- ½ cup mayonnaise
- ½ cup sharp cheddar cheese, shredded
Topping
- ½ cup buttery crackers, crushed (about 12-15 crackers)
- Fresh parsley, chopped, for garnishing
Instructions
- Prepare the squash and onions: Place the sliced yellow squash and thinly sliced onion into a saucepan. Cover with water and add ½ teaspoon salt.
- Cook the vegetables: Cover the saucepan with a lid and simmer for 10-15 minutes or until the squash and onion become tender.
- Drain well: Remove the saucepan from heat and drain the cooked squash and onions thoroughly to remove excess water.
- Mix the casserole base: Transfer the cooked and drained squash and onions into a large mixing bowl. Add the mayonnaise, egg, sharp cheddar cheese, remaining ½ teaspoon salt, and black pepper. Stir everything together until evenly combined.
- Assemble the casserole: Grease a 2-quart (8×8 inch) casserole dish. Pour the squash mixture into the dish and level the surface evenly.
- Add the topping: Sprinkle the crushed buttery crackers evenly over the top of the casserole.
- Bake: Preheat the oven to 350°F (175°C). Place the casserole in the oven and bake for 25-30 minutes or until the casserole is bubbly and the cracker topping is golden brown.
- Garnish and serve: Remove the casserole from the oven and let it cool slightly for 1-2 minutes. Garnish with freshly chopped parsley before serving.
Notes
- Be sure to drain the cooked squash and onions very well to avoid a watery casserole.
- Use sharp cheddar cheese for a pronounced cheesy flavor; mild cheddar can be substituted if preferred.
- The buttery cracker topping adds a nice crunch – buttery Ritz crackers work wonderfully.
- This casserole can be served as a side dish or a vegetarian main course.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven.
