Key Ingredients & Substitutions
Yellow Squash: This dish is all about the yellow squash! You can use zucchini if squash isn’t available; both add a lovely texture and flavor.
Green Chiles: I love using roasted green chiles for their smoky flavor! If you can’t find fresh or canned, jalapeños can be a good alternative for some spice.
Cheddar Cheese: Cheddar gives that classic flavor, but feel free to mix it up! Pepper Jack adds a fun kick, while a mild cheese like Monterey Jack works well if you prefer something less sharp.
Sour Cream: Greek yogurt is a great substitute if you’re looking for a healthier option. It adds similar creaminess!
Breadcrumbs: The optional breadcrumb topping adds crunch. If you want a gluten-free option, try crushed tortilla chips instead!
How Do You Get the Perfect Texture for Casserole?
To achieve that creamy and set texture, start by making sure your yellow squash is nicely drained after cooking. Excess moisture can make the casserole too watery, which is not what we want! Here’s how to prep it:
- Slice the squash evenly so it cooks uniformly and gets tender.
- Boil briefly and then drain really well. Use a paper towel to pat the slices dry.
- Mix your wet ingredients carefully; overmixing can make it tough.
- Watch the baking time; you want it set but not dry, so 35-40 minutes is usually just right!
Let the casserole cool for a few minutes before serving. This allows it to firm up a bit more, making it easier to cut and serve!

How Much Time Will You Need?
This Cheesy Green Chile Yellow Squash Casserole takes about 15 minutes to prepare and then 35 to 40 minutes to bake. Overall, you’ll need around 55 to 60 minutes, including a little time for cooling. It’s a perfect dish for a cozy family meal or gathering with friends!
Step-by-Step Instructions:
1. Preheat Your Oven:
Start by preheating your oven to 350°F (175°C). This ensures it’s just right when your casserole is ready to bake! Lightly grease a 9×13 inch casserole dish with cooking spray or butter to prevent sticking.
2. Cook the Squash:
In a large pot, bring water to a boil with a pinch of salt. Add the sliced yellow squash and cook for about 5 minutes, just until they are tender but not mushy. Once done, drain the squash well and gently pat it dry with a paper towel to remove excess moisture.
3. Mix the Vegetables:
In a big bowl, combine the drained squash with the diced onions and chopped green chiles. Give it a good mix to combine the flavors!
4. Prepare the Wet Mixture:
In another bowl, whisk together the eggs, sour cream, milk, melted butter, and garlic powder. Season with salt and black pepper. Gradually stir in the flour until everything is well mixed and smooth.
5. Combine Everything:
Pour the wet mixture over the squash and vegetables in the big bowl. Toss gently to ensure all the veggies are coated with the creamy mixture. Then, fold in 1 cup of the shredded cheddar cheese and all of the Monterey Jack cheese.
6. Transfer and Top:
Transfer everything to the prepared casserole dish and spread it evenly. Sprinkle the remaining ½ cup of cheddar cheese over the top. If you’re feeling adventurous, add breadcrumbs or crushed crackers on top for an extra crunch!
7. Bake to Perfection:
Pop the casserole in the preheated oven and bake uncovered for 35 to 40 minutes, or until it’s set and the top is all golden brown and bubbly.
8. Cool and Serve:
Once it’s done, carefully take it out of the oven and let it cool for about 5 minutes before serving. This helps it hold its shape. Enjoy your cheesy, spicy, and comforting green chile yellow squash casserole!
FAQ for Cheesy Green Chile Yellow Squash Casserole
Can I Use Zucchini Instead of Yellow Squash?
Absolutely! Zucchini can be a perfect substitute. It has a similar texture and will still work well with the other ingredients.
How Can I Make This Recipe Gluten-Free?
To make the casserole gluten-free, simply substitute all-purpose flour with a gluten-free flour blend. Additionally, use gluten-free breadcrumbs or omit the topping entirely for a flourless version!
Can I Prepare This Casserole in Advance?
Yes, you can prep the casserole a day in advance! Just follow the instructions until right before baking. Cover it tightly and refrigerate overnight. When you’re ready to bake, take it out of the fridge and allow it to sit at room temperature for about 30 minutes before popping it in the oven.
What’s the Best Way to Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, use the microwave or warm them in the oven at 350°F (175°C) until heated through. Adding a splash of milk before reheating can help maintain the creamy texture!
