Summer Squash and Onion Cheesy Casserole

  4.1 – 12 reviews  • Summer Squash

When I was a child, my Great Great Grandmother used to cook this, and my relatives in Atlanta and Alabama have always loved it! When I visited my Aunt Edith Russell in Atlanta in the mid-1990s, she taught me how to prepare it.

Prep Time: 15 mins
Cook Time: 45 mins
Total Time: 1 hr
Servings: 8
Yield: 8 servings

Ingredients

  1. 1 ½ tablespoons butter, divided
  2. 3 summer squash, trimmed and cut into bite-size pieces
  3. 3 zucchini, trimmed and cut into bite-size pieces
  4. salt and ground black pepper to taste
  5. 3 onions, chopped
  6. 1 pound shredded sharp white Cheddar cheese
  7. ½ pound shredded Cheddar cheese
  8. 3 tablespoons sweetened condensed milk, divided

Instructions

  1. Preheat oven to 350 degrees F (175 degrees C). Grease a 9×9-inch baking dish with about 1/2 tablespoon of butter.
  2. Melt remaining 1 tablespoon of butter in a large cast-iron skillet over medium heat, and cook the summer squash and zucchini until the squash pieces begin to brown, 10 to 15 minutes, stirring often. Sprinkle with salt and black pepper, and spread into the bottom of the prepared baking dish. Sprinkle with about 1/3 of the chopped onions.
  3. Mix together the white Cheddar cheese and yellow Cheddar cheese in a bowl until thoroughly combined, and sprinkle about 1/2 cup of the cheese mixture over the onions. Drizzle with about 1 tablespoon of the sweetened condensed milk. Repeat sprinkling cheese, onions, and condensed milk twice more, then top with remaining cheese mixture.
  4. Bake in the preheated oven until the casserole is golden brown and the onions are tender, about 30 minutes.

Yes I did I put garlic , scallion onions, accent, a dash of red pepper, and I used panko bread crumbs I seasoned the bread crumbs with a little thyme and Italian seasoning, and I used 34 cup of heavy cream. And everything in this recipe. And it was delicious. I always like to put my touch on recipes. And I love this recipe. And my family enjoyed it.!! Thanks.

Very good!! Added some mushrooms i had left over from meatball calzones last night and doubled it. Also used a dutch oven so it was a 1 pan kind-of meal! It was perfect!

My boyfriend made this exactly as written and found it rather bland. I thought the onions overpowered the veggies and cheese. If we make this again, we will cut the onions in rings instead.
James Perez
This was just okay for me. I really didn’t enjoy the sweetness of the condensed milk mixed in with my veggies and cheese.

Vegetables took forever to cook. I put it in for a lot longer than the recipe stated, and even tried to cook it longer after I had put it away in the fridge for the night. I wanted to like this, it was just too blah. Don’t know what spices I would use, but it definitely needs something more. Probably won’t make this again. Too much work for the taste.
Chase Zimmerman
I liked this a lot, very rich!
Andre Bush
One word to describe this recipe: DELICIOUS! It was very easy and very tasty and I will make it many many times!
Maria Nelson
With a very minor change this was great! Following another reviewer’s suggestion, I sauteed the squash with the onion, and it was fantastic. I was a little concerned about the condensed milk, so I drizzled it lightly off of a spoon onto the top of the cheese layers. I’m not sure that I used quite the amount called for, but it added just the right touch of sweetness for our family. Thanks for another great summer garden recipe!

It was good but in the future I will cook the onions ahead of time as they came out a bit on the crunchy side. I will also up the temp as at 350 for 30 mins, it didn’t brown and there was a little too much liquid. I may also leave the skin on as it is a little monochromatic.
Kevin Garner
Good, but I think next time I would mix the onions throughout. An easy way to eat vegetables that aren’t my favorites other ways!
Mark Anderson
This is one of my all time favorites! I actually use more butter and sweetened condensed milk than the “official” version calls for, but it is a matter of taste!
Bill Brown
It is a nice alternative to cheesy hashbrowns, but it lacked a wow factor.
