This Easy Green Chile Yellow Squash Casserole combines tender yellow squash with zesty green chiles for a tasty dish that’s perfect for any meal! It’s cheesy, warm, and oh-so-comforting.
I love making this casserole when I have a ton of squash from the garden. Plus, it’s so simple to whip up—you just mix, bake, and enjoy the deliciousness with family!
Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash gives this dish a lovely texture and mild flavor. If you can’t find yellow squash, zucchini works well as a substitute, offering a similar taste and texture.
Diced Green Chiles: The 4 oz can adds a nice kick. If you’re looking for something milder, try using canned jalapeños or even bell peppers. For a fresh option, sauté some fresh green chiles instead.
Cheddar Cheese: I love using sharp cheddar for a bold flavor, but feel free to swap with Monterey Jack or Pepper Jack for extra spice. A cheese blend can also work wonderfully in this casserole.
Sour Cream & Mayonnaise: These add creaminess. For a lighter option, use Greek yogurt instead of sour cream, and you can skip the mayonnaise altogether if you wish!
Crushed Buttery Crackers: Ritz crackers add a buttery crunch. You can substitute with breadcrumbs or other crackers if you need a gluten-free option. Just crush them up the same way!
How Do You Get the Squash Nice and Tender?
Sautéing the squash and onions is key to getting them tender and flavorful. Here’s how to do it right:
- Heat a skillet over medium heat and add a bit of oil or butter.
- Add your sliced squash and chopped onion, cooking them for about 5-7 minutes until they soften. Stir occasionally.
- If you notice excess moisture, drain it to prevent the casserole from becoming watery.
Taking the time to sauté gives the squash a delicious depth of flavor that really shines through in the casserole!

Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This ensures it’s nice and hot when you’re ready to bake the casserole.
2. Sauté the Vegetables:
In a large skillet, add a touch of oil or butter and heat it over medium heat. Toss in the thinly sliced yellow squash and finely chopped onion. Sauté for about 5-7 minutes, or until everything is tender. If there’s excess moisture, you can drain it to keep the casserole from being too runny.

4. Prepare for Baking:
Next, take a greased 9×9-inch baking dish and pour the squash mixture into it, spreading it evenly.
5. Make the Cracker Topping:
In a small bowl, mix the crushed buttery crackers with the melted butter until the crumbs are nicely coated. Sprinkle this mixture evenly over the top of the casserole.
6. Bake the Casserole:
Place the dish in your preheated oven and bake for 25-30 minutes. You’re looking for a nice golden brown topping and bubbly goodness around the edges.
7. Let it Cool & Serve:
Once done, remove the casserole from the oven and allow it to cool for a few minutes before serving. This dish is comforting and bursting with flavor—enjoy!
