Cheesy Summer Squash Casserole

Many were intrigued by the squash casserole that my dad made a couple of weeks ago while I was in Florida and I received requests for a recipe.

I was happy to create my own version of squash casserole to share with you guys today! I served this recipe to some friends who came over for dinner last night and all of us went back for seconds. Safe to say it’s a winner!

CHEESY SUMMER SQUASH CASSEROLE 

Cheesy Summer Squash Casserole

Using summer squash for a cheesy casserole with a crispy panko topping is probably my favorite way to eat it. I mean, what’s not to love about cheese + crunch?

The ingredients line-up is pretty simple.

Step one is to saute the squash and onion in some butter.

While the squash is cooking, stir together the cheesy mixture of greek yogurt (or sour cream), mayo and shredded cheddar cheese.

Stir cheese mixture into sautéed squash.

Top with panko bread crumbs that are tossed with melted butter and a little more cheese.

And bake! Easy, peasy.

The result is a warm, gooey, cheesy inside that has the perfect amount of tang thanks to the yogurt/sour cream. The crispy, buttery Panko topping balances out the texture so well.

One option to kick it up a notch when it comes to flavor profile is to add some cayenne pepper to the squash when it’s sautéing. Skip this if you don’t like the heat but my friends really enjoyed the addition when I served the squash casserole with dinner last night.

Here’s the recipe!

Instructions

1. Preheat oven to 350 degrees.
2. Melt 2 tablespoons of butter in a large nonstick pan over medium-high heat. Saute squash and onions for 10-15 minutes, stirring frequently, until squash starts to soften and onions become translucent.
3. While squash is cooking, mix together yogurt or sour cream, mayonnaise and 1 cup of shredded cheddar cheese.
4. Once squash is done sauteing, remove from heat and add yogurt and cheese mixture to the pan. Stir to coat squash well.
5. Transfer mixture to an 8×8 square baking dish.
6. Melt remaining two tablespoons of butter in a small bowl and then add panko and remaining 1/2 cup of cheese. You might also add a sprinkle of salt to the panko mixture, especially if you are using unsalted butter. Stir to coat panko in butter and incorporate cheese.
7. Sprinkle panko topping over squash mixture.
8. Bake for 25-30 minutes at 350 until topping is lightly browned and casserole is a bit bubbly.
