Ray’s Killer Creek Squash Casserole

I’ll never forget the first time I tasted squash casserole. It was at my Aunt Carol’s annual Thanksgiving feast, a sprawling buffet of Southern comfort food. Tucked amongst the sweet potato pie and cranberry sauce was this unassuming, golden-brown dish. One bite, and I was hooked. The creamy, savory squash, punctuated by the crunch of those iconic fried onions, was an absolute revelation. It was sunshine on a plate, a taste of pure, unadulterated happiness. Over the years, I’ve experimented with countless squash casserole recipes, but Ray’s Killer Creek version… well, let’s just say it lives up to its name.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 35 minutes
• Total Time: 55 minutes
• Servings: 12
• Yield: 1 large casserole
• Dietary Type: Vegetarian (can be adapted to gluten-free)

Ingredients

• 5 lbs yellow squash, cut into ¼ inch slices
• 3 cups mayonnaise
• 1 cup yellow onion, diced
• 6 eggs
• ¾ lb (3 sticks) butter, melted
• ¼ lb cheddar cheese, grated
• 1 teaspoon granulated sugar
• 1 teaspoon salt
• 1 teaspoon black pepper, ground
• 1 cup French’s French Fried Onions

Equipment Needed

• 10×15 inch roasting pan
• Large mixing bowl
• Knife
• Cutting board
• Measuring cups and spoons

Instructions

1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). While the oven heats, lightly grease a 10×15 inch roasting pan. A little bit of butter or cooking spray will do the trick. This ensures the casserole won’t stick and makes serving a breeze.

2. In a large bowl, combine the sliced yellow squash, mayonnaise, diced yellow onion, eggs, melted butter, grated cheddar cheese, sugar, salt, and pepper.

3. Mix all ingredients thoroughly until everything is evenly distributed. Don’t be afraid to get your hands in there! Make sure the squash is well-coated with the creamy mixture.

4. Pour the mixture into the prepared roasting pan, spreading it out evenly to ensure uniform cooking.

5. Bake for 30 minutes, or until the casserole is bubbling and starting to set around the edges. Keep an eye on it – ovens can vary.

6. Remove the casserole from the oven and sprinkle the French Fried Onions evenly over the top.

7. Return the casserole to the oven and continue baking for another 5 minutes, or until the top is golden brown and the onions are crispy.

8. Remove from oven and let cool slightly before serving.

Expert Tips & Tricks

• Squash Selection: Choose firm, unblemished yellow squash for the best texture and flavor. Smaller squash tend to be less seedy.
• Mayonnaise Matters: While you can use light mayonnaise, full-fat mayonnaise will give you the richest, creamiest result.
• Cheese Choices: Feel free to experiment with different cheeses. Monterey Jack, Colby Jack, or even a sharp provolone would all be delicious alternatives to cheddar.
• Preventing a Watery Casserole: Squash can release a lot of moisture during cooking. To combat this, you can lightly salt the sliced squash and let it sit in a colander for about 30 minutes before mixing it with the other ingredients. This will draw out some of the excess water. Pat them dry before adding to the bowl.
• Make-Ahead Magic: Assemble the casserole up to 24 hours in advance, cover tightly, and refrigerate. Add the French fried onions just before baking to prevent them from getting soggy.
• Level Up with Herbs: For an extra layer of flavor, add a tablespoon of chopped fresh herbs like thyme, rosemary, or parsley to the squash mixture.
• Crispy Onion Perfection: Keep a close watch on the onions during the final baking phase. If they start to brown too quickly, loosely tent the casserole with foil to prevent them from burning.

Serving & Storage Suggestions

Serve Ray’s Killer Creek Squash Casserole warm, as a side dish alongside your favorite protein. It pairs beautifully with roasted chicken, grilled pork chops, or even a hearty vegetarian lentil loaf. Garnish with a sprinkle of fresh parsley or chives for a pop of color.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, bake in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) until heated through, or microwave in short intervals until warm. The casserole can also be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating. Note that the texture may change slightly after freezing.
