Today I’m going to share with you Granny Jordan’s English Pea Casserole. In simpler terms, Green Pea Casserole, which some folks even call a salad. She took it to just about every family gathering and countless church dinners. It’s one of those old-fashioned Southern side dish recipes you don’t hear about much these days but you sure do get rave reviews when you make it. I love it and I hope you will, too.

So, what exactly will you find in this old-fashioned Southern green pea casserole? Besides green peas, there’s onion, celery, and pimentos mixed together with creamy mushroom soup. Add a buttery bread crumb topping, bake for 30 minutes, and you’re good to go! The combination of the crunchy topping with the creamy veggies makes this the perfect side dish in my opinion (like my beloved green bean casserole).

We regularly serve it alongside baked ham at Easter, but I’ve included lots of other options below, so let’s get baking!

What You’ll Need to Make Green Pea Casserole:

green pea casserole ingredients

  • Plain bread crumbs
  • Pimentos
  • Onion
  • Salted or unsalted butter
  • Chopped celery
  • Water chestnuts
  • Cream of mushroom soup
  • Frozen sweet peas

How to Make Green Pea Casserole

pour peas in the bowl

Pour your peas into a large bowl.

add chopped onion

Toss in your chopped onion.

Now this recipe leaves our onion with a little bit of a crunch and I really like it that way. Mama can’t stand it though, so she likes to saute her onion a bit in a tablespoon or so of butter and then add it in. You go with whatever works best for you.

add in celery

Add in your celery.

add pimentos to green pea casserole mix

Add in your pimentos (after you drain them).

add in water chestnuts

Add in water chestnuts.

add cream of mushroom soup to green pea casserole mix

Toss in your cream of mushroom soup and give that all a good stir.

place green pea casserole mix into casserole dish

Pour it into a casserole dish.

I am using a round one but you can use an 8×8 if you like or pretty much any ovenproof dish. Here’s a really cute Casserole Dish if you’re in the market for one that will make your table look beautiful!

melt your butter and add in crumbs

Now, melt your butter in the microwave.

Add your bread crumbs to the melted butter, and give that a stir.

sprinkle bread crumb mixture over green pea casserole

Sprinkle over the top of the casserole.

bake green pea casserole

Now bake at 350 for 25-30 minutes or until golden brown like this on the top.

This makes a great side dish to any meal, but it seems like we always eat it with ham.


Store leftovers in an airtight container in the fridge for up to 4 days. To make the top crispy once more, you’ll want to reheat them in the oven or air fryer.

Recipe Notes

  • As mentioned in the recipe card below, you can add a can of water chestnuts to the casserole if you like for extra crunch.
  • Instead of the breadcrumb topping, you can use a stuffing mix, mix crushed Ritz crackers or cornflakes with the melted butter, use 1 cup of leftover cornbread crumbs, or add French fried onions on top (add this 5 minutes before the casserole is done baking).
  • Feel free to substitute the frozen peas for canned peas or fresh peas.
  • You can also substitute the mushroom soup for cream of celery soup.
  • If it isn’t a casserole without cheese, stir 1/2 cup of shredded cheddar cheese into the casserole dish before baking. 
  • For added heat, add a dash of cayenne pepper.

  1. I was reminiscing about old recipes that I lost in a fire several years ago, and one of them was for English pea casserole that I had gotten from my southern aunt. I decided to check your site and, of course, I found it! Her’called for slivered toasted almonds, but otherwise the same. I am prepared to make it very soon! Thanks, Christy, knew I could count on you!

  2. Happy Thanksgiving Christy to you and yours!
    I have to tell you I happened upon your website by accident but I am so happy to have found you! I have spent the last 8 years helping my Dad be the care team for my Mom with
    Alzheimers. We moved her o a care facility in April and I was feeling a bit lost. I stumbled on our website and found some comfort in your recipes and bible references. I live in Minnesota and have never been a “Southern” girl but I love reading the recipes and plan to try many. Thanks for being out there. I appreciate all that you do and offer!

  3. I loved this recipe. I doubled the bread crumb topping, cut the onions finely, and cooked for about 50 minutes so the celery and onions turned soft. YUM!

  4. Howdy very cool website!! Man .. Beautiful .. Superb .. I’ll borkmaok your blog and take the feeds additionally?I am happy to find so many helpful info right here in the submit, we’d like work out more strategies in this regard, thank you for sharing. . . . . .VA:F [1.9.10_1130]please wait…VA:F [1.9.10_1130](from 0 votes)

  5. Will have to try this, my daughter is allergic to mushrooms though, so will make it with cream of asparagus soup instead, since a lot of the posts talk about using asparagus in the casserole anyway.
    I think the salad would be good also, with sour cream and mayo, I never use miracle whip, don’t like the flavour, and don’t like to use pure mayo so the mix would be good. I love peas, and think this would be a neat way to make some up this summer.
    I do like your lovely casserole, and you have interested me in looking for some vintage ones of my own. LOL As if I needed incentive!
