We have yellow squash coming out of our ears right now from our garden.   And this Squash Casserole with Green Chile is our all-time favorite of all our summer squash recipes.    It has the perfect balance of flavor and is one great way to make the most out of our fresh yellow squash.

This amazing Squash casserole is loaded with cheeses and green chile.  And it’s topped with a breadcrumb parmesan cheese crumble.   It’s out of this world delicious.  Even some of your picky eaters might ask for a second helping of this Squash Casserole. 

 
Summer Squash and onions

 

Start off by thinly slicing 6 medium yellow squash and 1 large yellow onion.   Heat butter in a large skillet or wok and saute the yellow squash and the onion slices until the onions are translucent.

Add the cooked squash and onions into a large mixing bowl.  Then add the green chiles, cheeses, sour cream, salt, and pepper.    Gently mix until well combined and pour into a  2-quart baking dish that’s been lightly oiled.

Mix the Parmesan cheese, breadcrumbs, and 1 tbsp melted butter in a small dish.    Then sprinkle the crumb mixture on top of this casserole.

Bake, uncovered for 20 minutes until the topping is golden.   Remove from oven and allow to cool for 5-10 minutes prior to serving.     Garnish with chopped parsley if desired.

We are thinking about making a few of these squash casseroles and freezing them.    We love freezer meals and having a vegetable casserole in the freezer would be a treat this winter when the garden is gone.   A bubbling pan of summer squash would go well with our Thanksgiving Turkey or our Christmas Baked Ham with Pineapple Glaze.

I added chicken to make it a whole meal and used Ritz crumbs instead of bread crumbs because I was out. Delish!

Excellent..used 3 squash and 3 zucchini because that’s what I had..also use 2-7oz cans of diced fire roasted chilis as couldn’t find fresh locally..the only other thing I will do differently is double the topping..this was better than desert!!
