This Easy Cheesy Green Chile Yellow Squash Casserole is a warm and cheesy delight! With tender yellow squash and zesty green chiles, it’s packed with flavor.

Honestly, what’s better than a cheesy dish that makes veggies exciting? I love serving it as a tasty side—you’ll have everyone asking for seconds!

Key Ingredients & Substitutions

Yellow Squash: This is the star of the dish! Choose fresh, firm yellow squash for the best texture. If you can’t find yellow squash, zucchini works fine as a substitute.

Green Chiles: Diced green chiles add a lovely kick! Use canned ones for convenience. If you prefer a milder flavor, try using diced bell peppers instead.

Cheddar and Monterey Jack Cheese: I love sharp cheddar for its bold flavor. You could swap Monterey Jack with Pepper Jack for a spicier taste, or even use a dairy-free cheese if needed.

Sour Cream: This adds creaminess and tang. Greek yogurt is a great substitute if you want something healthier. Just make sure it’s plain and unsweetened.

Onion: For a sweeter flavor, use sweet onions like Vidalia. If onions aren’t your thing, feel free to leave them out or use leeks instead.

How Do I Get a Perfectly Baked Casserole?

Baking the casserole properly ensures a wonderful texture and flavor. Here’s how you can do it right:

  • Preheat your oven thoroughly before baking. This helps the casserole cook evenly.
  • Watch the cooking time! Check if it’s golden brown on top and set in the middle. If it’s browning too fast, cover it with foil.
  • Let it rest after baking! This allows the casserole to settle, making it easier to cut and serve.

These simple steps will help ensure your casserole turns out delicious every time!

How to Make Easy Cheesy Green Chile Yellow Squash Casserole

Ingredients You’ll Need:

Fresh Vegetables:

  • 4 cups yellow squash, thinly sliced
  • 1 cup diced green chiles (mild or roasted)
  • 1 medium onion, finely chopped

Creamy and Cheesy Goodness:

  • 1 cup sharp cheddar cheese, shredded
  • 1/2 cup Monterey Jack cheese, shredded
  • 1/2 cup sour cream
  • 1/4 cup all-purpose flour
  • 3 large eggs

Seasonings and Extras:

  • 2 tbsp butter (plus extra for greasing)
  • 1 tsp garlic powder
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp ground cumin (optional)
  • 1/4 cup grated Parmesan cheese (for topping)

How Much Time Will You Need?

This delightful casserole takes about 10 minutes to prepare and 30 to 35 minutes to bake. You’ll spend a little time slicing veggies and mixing ingredients, but it’s quite straightforward. Total time: about 45 minutes!

Step-by-Step Instructions:

1. Preheat Your Oven:

Start by preheating your oven to 350°F (175°C). This ensures it’s hot and ready for the casserole. While it’s heating, butter your 9-inch cast-iron skillet or casserole dish so the casserole doesn’t stick.

2. Sauté the Onions:

In your skillet, melt the butter over medium heat. Add the chopped onions and cook them until they are softened and translucent, which should take around 5 minutes. Stir occasionally to prevent burning!

3. Cook the Yellow Squash:

Add the thinly sliced yellow squash to the skillet. Stir frequently and cook until the squash is tender but not mushy—about 8 minutes. Once done, remove the skillet from heat and let the mixture cool slightly.

4. Mix the Egg and Cream Mixture:

In a large mixing bowl, whisk together the eggs, sour cream, flour, garlic powder, salt, pepper, and optional cumin until it’s nice and smooth. This will be the creamy base of your casserole.

5. Combine Everything:

Add the cooked onion and yellow squash mixture, along with the diced green chiles and shredded cheeses to the egg mixture. Stir everything together until it’s all evenly combined.

6. Bake the Casserole:

Pour the entire mixture into your prepared skillet or casserole dish. Spread it evenly across the pan. Finally, sprinkle the grated Parmesan cheese on top for an extra cheesy crust.

7. Time to Bake:

Place the casserole in the preheated oven and bake for 30 to 35 minutes. You’ll know it’s done when it’s set and golden brown on top. If you poke it with a knife in the center, it should come out clean.

8. Serve and Enjoy:

Once baked, let it cool for a few minutes before serving. This dish is perfect as a side or even as a main course. Enjoy your cheesy, zesty yellow squash casserole!
