Ingredients You’ll Need

(Serves 6-8 | Prep Time: 10 minutes | Cook Time: 40-45 minutes)

  • 1.5-2 lbs yellow squash, sliced
  • 1 stick (½ cup) butter, melted
  • 8 oz package Pepperidge Farm stuffing mix
  • 1 can (10.5 oz) cream of chicken soup
  • 1 onion, finely chopped
  • ½ stalk celery, thinly sliced
  • 1 cup sharp cheddar cheese, grated

Step-by-Step Instructions

1. Preheat the Oven

preheat my oven to 350°F and grease a 13×9-inch baking dish to prevent sticking.

2. Cook the Squash

In a large pot of lightly salted water, I steam the sliced squash until tender—about 5-7 minutes. Once done, I drain it well to remove excess moisture.

3. Mix Everything Together

In the prepared baking dish, I combine:

  • Steamed squash
  • Melted butter
  • Stuffing mix
  • Cream of chicken soup
  • Chopped onion
  • Sliced celery
  • Shredded cheddar cheese

stir everything together, making sure the squash is evenly coated with the creamy, cheesy mixture.

4. Bake Until Golden & Bubbly

I place the dish in the preheated oven and bake for 40-45 minutes, or until the top is golden brown and bubbly.

5. Rest & Serve

Once baked, I let the casserole sit for 5-10 minutes before serving. This helps the flavors meld together and makes slicing easier.

Pro Tips for the Best Squash Casserole

  • Drain the Squash Well – After steaming, I make sure to drain any excess water so the casserole doesn’t turn soggy.
  • Use Fresh or Frozen Squash – Fresh squash is best, but frozen squash works too—just thaw and drain it wellbefore using.
  • Want Extra Crunch? – Sprinkle a little more stuffing mix or crushed crackers on top before baking.
  • Prefer a Softer Texture? – Sauté the onions and celery before mixing them into the casserole.
  • Make it Vegetarian – Swap the cream of chicken soup for cream of mushroom soup for a meat-free version.

What to Serve with Squash Casserole

This rich and cheesy casserole pairs beautifully with a variety of main dishes:

  • Southern Fried Chicken – The crispy, golden chicken complements the creamy squash perfectly.
  • Grilled Pork Chops – The savory pork and cheesy casserole make an amazing combination.
  • Oven-Roasted Turkey – A classic pairing for Thanksgiving or holiday dinners.
  • BBQ Ribs or Pulled Pork – The sweet, smoky flavors of BBQ contrast beautifully with the creamy casserole.
  • Fresh Green Salad – A light, crisp salad balances out the richness of the dish.

FAQs (From My Kitchen to Yours)

Q: Can I make this casserole ahead of time?
A: Yes! Assemble the casserole up to a day in advance, cover it tightly, and refrigerate. When ready to bake, add an extra 5-10 minutes to the cooking time.

Q: Can I freeze squash casserole?
A: Yes! Bake it first, let it cool completely, then wrap it tightly and freeze for up to 3 months. To reheat, bake at 350°F for 25-30 minutes until warmed through.

Q: Can I use zucchini instead of yellow squash?
A: Absolutely! Zucchini has a slightly different texture but works well in this recipe.

Q: What’s the best way to reheat leftovers?
A: Cover with foil and reheat in a 350°F oven for 15-20 minutes, or microwave in 30-second bursts until warm.
