Kitchen Essential: 

Slicing squash and onions can be a tedious task.  I highly recommend picking up a rotary grater to make this step a breeze.  This one is my absolute favorite because you can swap out the blades for premium sliceability.  Go from slicing squash and onions to shredding cheese to grating Ritz crackers.  All with the same kitchen gadget. 

Why You’ll Love This Southern Squash Casserole

A southern squash casserole combines simple, everyday ingredients into something truly delicious. It’s made with fresh yellow squash, onions, a cheesy filling, and a crispy topping of buttery Ritz crackers. It’s the perfect blend of savory, creamy, and crunchy—a combination that’s sure to become a family favorite.

Squash casserole is a versatile side that pairs wonderfully with a variety of meals. Serve it with oven-roasted meats like chicken, pork tenderloin, or even alongside turkey and ham. Because of its simple yet indulgent nature, this casserole shines on any table, whether it’s for a special holiday like Thanksgiving or just a casual dinner night.

When is Yellow Squash in Season?

Yellow squash, one of the stars of this dish, is typically in season during the summer months. In the U.S., you can find fresh yellow squash from late May through early September. However, because squash stores well and is readily available in most grocery stores year-round, you can enjoy this yellow squash casserole recipe anytime!

When selecting squash, look for ones that are firm and feel heavy for their size. The skin should be smooth without any wrinkles or blemishes. Smaller squash tends to have a sweeter, more tender flavor, making them perfect for squash casserole recipes.

Ingredients for Squash Casserole:

  • 3-4 fresh, yellow squash, about 4 cups once sliced
  • 1 small onion
  • 1-2 TBSP olive oil 
  • 1 can (10.5 oz) cream of mushroom soup
  • 1 ½ cups sharp shredded cheddar cheese
  • 2 tsp garlic powder, divided
  • 1 tsp pepper, divided
  • ½  tsp salt
  • 1 cup sour cream
  • 1 egg
  • About 30 Ritz crackers (one sleeve), crushed
  • ¼ cup butter, melted

How to Make the Best Squash Casserole:

This squash casserole with cream of mushroom soup is incredibly easy to make, requiring just a few steps and ingredients that are likely already in your pantry. Let’s break it down!

*printable recipe card is available at the bottom of this page

Step 1: Slice and Sauté the Squash

The key to achieving a tender casserole is sautéing the squash and onions first. This helps soften the vegetables and remove some of the excess water. No one wants a watery casserole, right? As you’re cooking the squash, season it with garlic powder, salt, and pepper to enhance its flavor.

Step 2: Drain the Squash

After cooking the squash and onions, make sure to drain them well. Squash contains a lot of water, and draining it will prevent your casserole from becoming soggy. Gently press down with a spatula to squeeze out as much liquid as possible.

Step 3: Prepare the Filling

The filling for this best yellow squash casserole recipe is rich and creamy, thanks to ingredients like sour cream, cream of mushroom soup, cheddar cheese, and an egg to hold everything together. Combining these creates a comforting, cheesy base that makes every bite indulgent. Mix in the squash and onions until well combined.

Step 4: Assemble the casserole:

Pour the filling into the prepared baking dish, spreading it evenly.

Step 5: Add the Crunchy Ritz Cracker Topping

Ah, the topping—the Ritz cracker squash casserole wouldn’t be complete without it! The buttery cracker crumbs create a crispy, golden layer on top, adding the perfect contrast to the creamy filling underneath. Toss the crushed Ritz crackers with melted butter before sprinkling them evenly over the casserole.

Step 6: Bake Until Golden Brown

Pop your assembled casserole into the oven and bake it until the top is a deep golden brown. For an extra bit of crunch, broil it for the last couple of minutes—but keep a close eye on it to prevent burning.

Tips for the Best Squash Casserole Recipe

To make sure your casserole comes out perfectly every time, here are a few tips:

  • Drain the squash: As mentioned earlier, squash contains a lot of water. Make sure you sauté the squash well and press out as much liquid as possible to avoid a watery casserole.
  • Use fresh yellow squash: If possible, use fresh, in-season squash for the best flavor and texture.
  • Customize the cheese: Sharp cheddar cheese adds a delicious tangy flavor, but you can experiment with other cheeses like Monterey Jack or Parmesan for a different twist.
  • Make it ahead: This casserole can be made in advance. Simply assemble it, cover it, and store it in the fridge until you’re ready to bake. It’s a time-saver for busy holiday cooking!

        At 66 years of age, I have only recently been introduced to squash. I was quite surprised how tender and flavorful they are. I may even grow a couple in my garden next year. I don’t need much since I only cook for me, myself, and I at this stage in my life. I’m excited to make this dish for an upcoming family event. Thank you for sharing!

    We aren’t big squash eaters, but this looks so interesting and different, I have to try it. Doesn’t look too difficult and I have that big slicer that you use yourself.

    Every year I bring a new vegetable side dish for Thanksgiving and this one seems to be the winner for our holiday table. I don’t know who could resist a yellow squash casserole with squash, cheese, and a creamy sauce made from soup mixed with sour cream. Of course, I must make a batch before the holidays as a taste test.

    This recipe brought back memories! My mother made squash casserole every Thanksgiving and she unfortunately passed away suddenly right before I got married and had to make my first Thanksgiving dinner- without any of her beloved recipes.
