The Best Squash Casserole

Who would ever think to cook squash in a casserole? It seems like an unlikely choice, but it’s truly genius.

I can’t remember the first time I tasted squash. Mom loved to fry it in a skillet, and Granny Tag liked to whip it into a soufflé. It was always on our dinner table in some form or fashion.

Back in the 70’s, and even before that, using cream of mushroom soup was a popular way to bind a casserole together. This time around, I wanted to try a different approach. And, guess what? The results were amazing!

What You’ll Need for This Recipe

SQUASH

• 1 Tbsp. butter
• 3 large yellow squash, quartered and diced
• 1 sweet onion, diced
• 1/2 tsp. all purpose seasoning
• dash of garlic powder

FILLING

• 1 cup sour cream
• 1/2 cup mayonnaise (I use Duke’s) ad
• 8 oz. pkg. sharp cheddar cheese, shredded
• 1 cup parmesan cheese, shredded
• 2 eggs, beaten

TOPPING

• 1/4 stick butter, melted
• 1 sleeve Ritz crackers, crushed
• 1/2 cup french fried onions, crushed

How to Make Squash Casserole

Sautéing onions with the squash beforehand gives the casserole its robust flavor. I also took a hint from Granny Tag, and added eggs to sour cream and mayonnaise for the creamy base.

And here’s the tip of the day…if one cheese is good, then why not go for two? Sharp cheddar blended with shredded parmesan is kinda amazing. I also like to add a dash of garlic powder for flavor.

Top it all off with buttery crackers mixed with some fried onions…and, well…there are no words.

I know you’ve been making squash casserole for years, but y’all…this recipe is killer! Give it a whirl…and be sure to leave a comment telling me what you think.

Duke’s Mayonnaise (ad) is a southern favorite and the only mayonnaise I recommend.
