Your Next Hearty Side: Yellow Squash Casserole

When it comes to veggies that are readily available, one of my faves is yellow squash. I love to have it steamed with bell peppers and onions and fried, with the same. And when we have an abundance of yellow summer squash… we make a squash casserole!

Most yellow squash casseroles I’ve seen that are shared are comprised of squash, cheese and Ritz crackers. My squash casserole isn’t that. In fact, it has a way different flavor profile than what you may be used to.

What Ingredients Are Included In the Squash Casserole?

  • Yellow Squash
  • Onion
  • Green Bell Pepper
  • Cream of Chicken Mushroom Soup
  • Greek Yogurt or Sour Cream
  • Pepperidge Farm Dressing Mix
  • And the Surprise Ingredient…Shredded Carrots!

This yellow squash casserole is perfect to make any time of the year. It’s a delicious side dish to serve for any special holiday, from Easter to Thanksgiving to Christmas. But it’s especially great to cook and serve during the months when yellow squash is plentiful. It’s a bonus if you grow yellow squash in your own garden or have access to a farmer’s market or local produce stand.

As a tip: I’ve found that the fresher the squash — like home grown — the less water it produces when it is cooked.

With credit to the Pepperidge Farm dressing mix, this yellow squash casserole is a hearty and filling side. And with the addition of onions, peppers and carrots, it’s a great well-rounded vegetarian dish (if you swap out the cream of chicken mushroom soup for cream of mushroom soup or even cream of celery soup.) And thanks to that can of cream soup, the casserole pairs well with most proteins, including chicken, beef, pork and fish, that are baked, grilled and sautéed.

What Unique Ingredient Is In This Yellow Squash Casserole Recipe?

It’s the shredded carrots, which are the perfect addition! They add color, fiber, flavor, sweetness, and most importantly, additional texture to contrast some of the natural mushiness you get with squash . Other squash casserole recipes with cheese and butter crackerers are yummy, but this yellow squash casserole recipe elevates the flavor profile up a notch.

What Goes Well With Squash Casserole?

As previously mentioned, this is a heartier vegetable dish, so you can easily serve this yellow squash casserole with a protein and make it a meal. Or you can add a summer, fruit or tossed salad or an additional green vegetable for a grander meal. Some of the menu ideas that pair perfectly with this yellow squash casserole include:

Can This Squash Casserole Be Made Ahead of Time?

Yes! This yellow squash casserole can be made the day before or hours before and refrigerated until it needs to be baked. Cover the squash mixture in the baking dish and do not add the Pepperidge Farm dressing topping until right before it is baked.

The smaller the squash, the more tender they are. But since this recipe has two cooking steps, larger, more firm squash can be used.

    I googled the Pepperidge farm dressing mix and the picture came up with Pepperidge farm STUFFING mix. (Herb variety)…is this correct?

    • 12.12.23

      Hi Lyn and thank you for taking the time to stop by. You are correct, this recipe calls for Herb Variety Pepperidge Farm stuffing mix. It’s true that we typically use the term “dressing” in the South! 😉

    I love squash! Could you bake the squash along with the onion and peppers and perhaps have less liquid?

    • 12.12.23

      Hi Joanna, I love squash, too! I’ve never tried baking the squash, so I’m not sure. I will say that I like my squash in casseroles to be fork tender, so the method I use seems to work best for that.

    This is my favorite squash casserole! I used to make this 30 years ago and had forgotten about it. I don’t care for the cheese and ritz cracker squash casserole. Thank you for reminding me of this one!

      Hi Sara, I’m happy to know that I provided a reminder to you to make this squash casserole again. I think it’s very unique and it’s my favorite!
