  • 6 cups sliced yellow squash (about 3 medium ones)
  • 1/2 cup chopped onion

Pantry Staples and Dairy

  • 1/4 cup butter, melted (for the casserole mix)

Step-by-Step Guide to Making Ultimate Cheesy Southern Yellow Squash Casserole Ritz

Okay, let’s get cooking! Making this ultimate cheesy yellow squash casserole is really straightforward. Just follow these steps, and you’ll have a wonderful dish ready to enjoy.

Preparing the Squash and Onion

First things first, we need to get our veggies ready. Grab a big pot and fill it with salted water.

Bring that water to a boil.

Add your sliced yellow squash and chopped onion to the boiling water.

Let them cook until they’re tender, which usually takes about 5 to 7 minutes.

It’s important not to overcook them here; we don’t want them mushy!

Once they’re tender, drain them really well. I like to let them sit in the colander for a few minutes to get rid of all that extra water.

Combining the Casserole Base

Now, grab a large bowl.

Add the drained squash and onion to the bowl.

Pour in the first 1/4 cup of melted butter.

Scoop in the can of condensed cream of mushroom soup.

Pour in the milk and add the shredded cheddar cheese.

Gently mix everything together.

Be careful not to mash the squash too much.

Season with salt and pepper to your liking.

Give it another gentle stir to make sure the seasoning is spread out.

Assembling and Baking the Ultimate Cheesy Southern Yellow Squash Casserole Ritz

Preheat your oven to 350°F (175°C).

Grease a 9×13 inch baking dish.

Pour the squash mixture evenly into the prepared dish.

Now for that amazing topping! In a small bowl, combine the crushed Ritz crackers and the second 1/4 cup of melted butter.

Stir them until all the crackers are coated in butter.

Sprinkle this buttery cracker mixture all over the top of the squash base.

Make sure it’s spread out nicely for that perfect crunch in every bite.

Place the dish in your preheated oven.

Bake for 20 to 25 minutes.

You’ll know it’s ready when the casserole is bubbly around the edges and the Ritz topping is golden brown and crispy.

Take it out of the oven and let it sit for a few minutes before serving.

This helps it set up a bit.

Expert Tips for Perfect Ultimate Cheesy Southern Yellow Squash Casserole Ritz

I want you to have the very best results with your cheesy yellow squash casserole! Here are a few little tricks I’ve picked up along the way:

  • Don’t overcook your squash! We want it tender, not falling apart. Just cook it until you can pierce it easily with a fork.
  • Make sure you drain the squash and onion really well after boiling. Too much water can make your casserole watery.
  • When you sprinkle on the Ritz cracker topping, try to get it as even as possible. That way, everyone gets that wonderful buttery crunch.
  • Let the casserole rest for about 5-10 minutes after it comes out of the oven. This helps the sauce thicken up a bit and makes serving easier.
  • Taste and adjust your salt and pepper before pouring the mixture into the dish. It’s easier to fix the seasoning then!

Following these simple tips will help ensure your ultimate cheesy yellow squash casserole with Ritz is a delicious success every time!

Variations on Your Ultimate Cheesy Southern Yellow Squash Casserole Ritz

One of the things I love about cooking is how easy it is to make a recipe your own! While this ultimate cheesy yellow squash casserole is fantastic as is, you can definitely play around with it.

Tried swapping the cheddar for Monterey Jack cheese? It gives a lovely, melty texture.

A blend of cheeses works wonderfully too!

If you like a little heat, a tiny pinch of red pepper flakes stirred into the squash mixture adds a nice kick without being overwhelming.

Don’t have Ritz crackers? Other buttery crackers or even plain breadcrumbs tossed with butter will work for the topping in a pinch, though I do think the buttery Ritz are special!

Serving Suggestions for Ultimate Cheesy Southern Yellow Squash Casserole Ritz

This ultimate cheesy yellow squash casserole is a fantastic side dish that goes with so many things!

It’s perfect alongside roasted chicken or a juicy pork tenderloin.

It also pairs beautifully with grilled fish or steak.

For a vegetarian meal, I love serving it next to some hearty black bean burgers or a simple green salad.

It’s truly versatile and always a welcome addition to the plate.

Storing and Reheating Your Ultimate Cheesy Southern Yellow Squash Casserole Ritz

Got leftovers? Lucky you! This cheesy yellow squash casserole stores really well.

Let it cool completely first.

Then, cover the dish tightly with plastic wrap or foil, or transfer leftovers to an airtight container.

It will keep in the refrigerator for up to 3-4 days.

To reheat, you can warm individual portions in the microwave.

Or, for the best texture, especially the topping, reheat the covered casserole in a 300°F (150°C) oven until heated through, about 15-20 minutes.

Frequently Asked Questions About Ultimate Cheesy Southern Yellow Squash Casserole Ritz

I get lots of questions about this ultimate cheesy yellow squash casserole, so I thought I’d answer a few common ones here!

Can I make this yellow squash casserole ahead of time? Yes, you can! You can assemble the casserole up to the point of adding the Ritz cracker topping. Cover it and keep it in the fridge. Add the topping just before baking so it stays crispy.

What if I don’t have cream of mushroom soup? You can use cream of chicken soup or even cream of celery soup as a substitute, though the mushroom soup gives it a classic flavor.

My squash casserole turned out watery. What happened? This usually happens if the squash wasn’t drained well enough after boiling. Make sure you let it sit in the colander for several minutes to really get the water out.

Can I add other vegetables to this Southern squash casserole? Absolutely! Some folks like to add chopped bell pepper or a little corn for extra color and flavor. Just make sure they are cooked tender along with the squash and onion.
