Pin This RecipeMy Mom gave me this recipe for The Ultimate Squash Casserole. She clipped it out of the paper a million years ago. She found it the last time I was at her house and we were looking at recipes. I love finding old recipes to try!
OMG! This was SO good! Seriously the best squash casserole we’ve ever eaten. Loaded with squash, bell pepper and onions. The house smelled so good while the veggies were cooking in the skillet! My favorite part of the casserole was the cheese. It really put the casserole over the top! This was super simple to make and could even be assembled ahead of time and baked later that day or the next day. This would be a great side dish for any summer cookouts and even the holidays!

If you use the powder bullion how many scoops
Looks delicious!! Can you add actual chicken pieces in here? Thank you!
I’m sure that would be fine.
I give this 10 stars. Best casserole recipe on the planet!
do you used condensed cream of mushroom soup or just regular?
I used Campbell’s condensed soup. I don’t know what you mean by “regular”
Love squash!! A teaspoon of salt seems like a lot, so would it be ok to reduce the amount? And where is it added, in sautéing the vegetables or in the cream soup mixture?
you can adjust the salt and pepper to your taste
How do you combine eggs? I see it in the ingredients but not the directions?
Step 3
Can this be made the night before and then baked the next morning? If so, would that change the baking time? Thanks!
You can do that. You will probably need to add 5 or 10 minutes to the baking time if baking straight out of the fridge
Can cream of chicken soup be used instead of mushroom? I hate casseroles made with cream of mushroom?
Sure – that will be fine. Enjoy!
Works just fine. I don't use mushroom soup either. Maybe back off the chicken bouillon a little.
Can I use another cream soup because my husband does not like anything mushroom?!
is this a summer squash recipe? From the picture it appears to yellow summer squash but I just want to check.
I used yellow squash
If using buillon how many cubes?
4 cubes
i am going to use the bullion cubes also. but dont you have to dissolve them in water? How much water did you use?
Brie- you want to crush the boullion cubes up. If you want to dissolve them, only use a tablespoon of hot water. You don’t want to add extra liquid to the casserole
You say in the directions, "eggs", but I don't see it in the ingredients. Other than that, looks yummy!
there are eggs in the ingredient list

the eggs are listed in the ingredients.
This looks so good. I like these old recipes, and I LIKE CREAM OF MUSHROOM SOUP!
Looks really good and I'll save it for when our neighbors are harvesting more than they can eat.
