Tired of the same old side dish recipes? Then you will love trying spinach tonight!

This nontraditional side is a great recipe change out of the norm of green beans and carrots. You could argue that Spinach casserole is a Southern Dish and I see it served a lot here in the south along side black eyed peas and other fried things that are not good for you – we call it “balance.” 

Spinach casserole is also a great dish to prep for holidays like Thanksgiving. 

Scroll to the bottom for a printable version of this post, including all measurements and instructions, so you can follow along in your kitchen without being on your phone. 

Here is what you need to gather to get started: 

  • frozen chopped spinach
  • cream cheese
  • condensed mushroom soup
  • minced garlic
  • pepper
  • salt
  • french fried onions for mixture
  • french fried onions for topping
  • optional – 2 tsp minced garlic

Fresh or Frozen Spinach?

When making creamed casseroles, I prefer to use FROZEN spinach that has already been defrosted and any excess water drained out of the package so your casserole does not get too soggy.

add creamed cheese and frozen but thawed spinach together with all the seasonings before adding in cream of condensed soup
Make sure your spinach is drained completely to avoid extra water in your casserole

Spinach Casserole Toppings

Other topping options: I love fried onion toppings and they are so complimentary to green casseroles like this one.

If you happen to not like these type of crunchy onions (or you are on a keto or low carb diet) but still want a topper, here are a few additional ways to top your spinach casserole:

  • Simply use shredded cheese – Cheddar is highly popular for nearly all casserole dishes
  • Ritz Crackers 
  • Ruffles potato chips always make a great crispy topping
  • Crispy, Cooked Bacon, chopped up and layered
  • Croutons
Crispy onions come in canistors in the french fried onion family, so many other toppings are great too like ritz, pretzels, and chips
Add a generous portion of crispy fried onions for a great crunchy topping

Creamed Spinach Casserole

It’s true that creamy casseroles can be made with all veggie types.

My favorite (most peoples favorite) is broccoli cheese casserole with ritz topping, but there really are a variety of amazing vegetables to choose from that make delicious and interesting side dishes!

Growing up, spinach always got a super bad rap (except with Popeye) and I shied away quite a bit.

But as an adult, I enjoy fresh and frozen spinach both and when wrapped up with cream cheese and the right seasonings, chopped spinach is a great way to get your greens AND enjoy them. 

Let’s get cooking!

Preheat oven to 350 and grease a 1-1/2 quart casserole dish with nonstick cooking spray.

Set aside.

Combine spinach and cream cheese in a mixing bowl.

Stir in soup, minced garlic, pepper and salt and mix well.

use a spatula to carefully combine all of your casserole ingrediants
This casserole reminds me quite a bit of a spinach dip!


Fold in 1 cup french fried onions.

Spoon into prepared baking pan.

Sprinkle with remaining french fried onions.

every spoonful of creamed spinach should have a generous portion of crunchy topping, so good with the cream cheese and a great delicious healthy side dish
Spinach Casserole is creamy, dense, and savory!

Bake for 20-25 minutes or until heated through and cream cheese is melted and serve.
