I’m super proud to share this recipe with y’all today! It “hails” from one of my very favorite women in the whole wide world. My Grandma Helen. She was an amazing cook…when she didn’t get too creative! lol (I’m still scarred for life over wheat germ in the pancake batter!)

 If you think I like to “tweak” a recipe…you should have met my Grandma! She was an AMAZING cook! I loved to watch her in the kitchen. She was a fierce machine in the kitchen.

One year, when I was staying at her house after Easter, there was a lot of leftover ham. Grandma said “Oh, We’ll just whip up one of my Ham, Pea, and Potato casseroles Nori!” (Her nick-name for me!) I was game! It had three of my favorite ingredients…seemed like a great idea to me.  

I watched as she made this amazing white creamy “gravy”, peeled & sliced a bunch of potatoes, cut up some of the leftover ham slices, and opened a can of peas. Then she started layering everything. Popped it into the oven and an hour later out came the BEST creamy ham, pea, and potato casserole. It was heavenly!

Ever since that first “lesson” I’ve been making Ham, Pea, and Potato casserole every year after the Holidays with our left over ham.

It’s pure comfort food and reminds me of my beautiful, passionate, fun Grandma. She truly was the hardest working lady I have ever known and reveled in the JOY of working!

Allow me to share a very personal family recipe with y’all today! I’m sure there are copy-cat recipes out there but this one has been around for at least 70 years! (And NO…that’s NOT how old I am!)

How To Make Grandma’s Ham, Pea, and Potato Casserole

Peel and slice 10 large potatoes. Cut out any brown spots. Slice them and place them in a large bowl of water so they won’t turn brown while you are making your “Roux”. (I use that “term” VERY , VERY loosely in this recipe)

Sliced Potatoes on a cutting board

Making “cream” sauces from scratch can be intimidating, but don’t let it be. It seems a lot scarier than it actually is.

In a large skillet, over medium heat, melt 1/4 cup of butter. I realize a “true Roux” uses clarified butter… “Hi! My name is Norine and welcome to my down home cooking blog!” Are we all on the same page now? Good! 😉

So back to our “country” Roux…melt the 1/4 cup of butter…Add in 1/2 cup of flour and stir quickly to form a thick paste. Slowly add in, while whisking briskly, 2 1/2 cups of milk.

Tip: ALWAYS use a whisk when making gravy, cream sauces, or cheese sauces. Reduces chance of lumps!

Butter in a skillet

Add in 1/2 tsp salt (I watch the salt in this dish between the salted butter and the ham…it’s sodium loaded! You can always add salt after you serve it!)  Add in the 1/2 tsp coarse black pepper. Continue stirring until thick and creamy.

TIP: If the sauce becomes too thick add more milk until you have a creamy white “gravy”.

White sauce for Ham, Pea, and Potato Casserole in a skilletDrain your potatoes. Spray a deep, 4 quart casserole dish, with cooking oil. Place 1/3 of the slice potatoes in the bottom of your casserole dish. Add a layer of sliced ham, you can used diced ham too if you don’t have leftover.

Layering sliced potatoes, ham, and white sauce in casserole dish

Sprinkle half the can of drained peas over the top of the ham and potatoes.

Adding Peas to Potatoes and Ham casserole

Pour 1/3 of the white sauce over the Ham and Potato layer. Repeat the layers again. Sliced potatoes, sliced ham, and the other half of the can of peas. Pour another 3rd of the sauce over the second layer.

Isn’t that starting to look amazing? This is such a yummy casserole!

Add the White Cream Sauce over the peas, potatoes, and ham.

Top off with the last 3rd of the potatoes and the remaining sauce. Sprinkle top with Paprika or fresh chopped parsley.

Potatoes sprinkled with Paprika, oven ready.

Place in a preheated 350°F oven for 1 hour, covered. After one hour remove lid, or foil covering, and place back in the oven for an additional 10 minutes to brown the top of the casserole.

Your potatoes should be “fork tender”. I always gently test by poking a few of the potatoes in the center of the casserole to make sure they are done.

Nothing I hate more than “crunchy” potatoes! This casserole needs to have tender tatters!

Baked Ham, Pea, and Potato Casserole.

The wonderful thing about this casserole…it’s a complete meal with the potatoes, meat, and peas. The cream sauce brings all those ingredients together beautifully.

This is a pure “comfort” dish! It’s so fantastic with that leftover ham. I used the Peach glazed ham leftovers so don’t worry if your ham had a glaze on it. It’s still going to be amazingly delicious!

There you have it friends! My Grandma Helen’s Ham, Pea, and Potato casserole in all its creamy glory! The potatoes are tender and delicious.

The ham just falls apart in this casserole, and is so delicious with that luscious cream sauce.  The Pea’s are the perfect “pop” of color and texture for this casserole.

Serve this casserole with a big green salad and fresh blueberry muffins! If you have Meat and “Tatter” lovers at your Nest…this is the dish for you! If you love down home comfort food…this is the dish for you!

I often wonder if Grandma was taught this recipe, or one similar, from her Mom who had 9 children and needed a filling yet delicious meal?

I can see it in my mind’s eye and I’d like to think that’s how this family favorite came to be.

This is perfect for your leftover holiday ham! I hope you love this casserole as much as we do! Grandma sure knew what she was doing!

    I gotta tell you that nothing makes me happier than this. I love, love casseroles and even though I don’t think I ever added easter ham, per se, I would love to try it soon. I do use leftover chicken, bacon and sometimes ground beef with peas and potatoes. I know this taste heavenly. I love the story behind it, too.

    • | 2nd Apr 17

      Hi Sandra! Loving your idea’s of adding potatoes and peas to ground beef and leftover chicken! Casseroles were a staple in our house growing up. Money was always tight and Mom was always looking for a way to stretch the main course! As a kid I didn’t realize why we had so many casseroles…I just knew I loved them and still do! 🙂 Thanks for your sweet comments! You’re the BEST!!! 😉

  2. Little Quiltsong | 4th Apr 17

    Norine – I just have to tell you that we had the above meal tonight – and it was scrumptious delicious. I used chopped ham, but otherwise totally did it like you said. I can’t remember when I was able to make a new recipe without tweaking it somewhere, but this was super and no tweaking needed. Thank you again, for such a delicious recipe.

    • | 7th Apr 17

      I’m so glad you enjoyed this casserole as much as we do! Thank you for your sweet comments! Grandma’s have the best recipes. Thank you for stopping by and sharing with me. Have a GREAT day!

  3. Carrie | 7th Apr 17

    Wow! Thanks for sharing this to timeless classic recipe. What a cool story to go along with it. I can’t wait to make this! Looks delicious.

    • | 7th Apr 17

      Thank you Carrie! I sure appreciate your kind comments. I can’t wait to hear how you like this casserole. I think Grandma had the BEST recipes! 😉
      Have a GREAT day!

  4. Elleblue | 20th Jul 17

    I love the look of this and will be trying it soon. The only change I’ll make is to substitute the white sauce with a cauliflower redo sauce, yum.

    • | 21st Jul 17

      That sounds like a wonderful redo! I’m excited to hear how it turns out. This is such a delicious dish and pure comfort food! Thanks for stopping by and visiting. Have a GREAT weekend!
      Happy Nesting!

  5. Ruth | 20th Dec 17

    Thanks for sharing your family recipe. It is just what I was looking for. I find it really hard to deal with leftover ham and usually just make soup or ham salad. Will be preparing this for supper tonight.

    • | 20th Dec 17

      Hi Ruth!
      I agree about “dealing” with leftover ham. One can only stand so much soup and so many ham and cheese omelettes! You will love this recipe. It’s pure comfort food. Grandma knew what she was doing. Thanks for stopping by and visiting with me. I hope you have a wonderful and Merry Christmas!
      Happy Nesting!

  6. The Better Baker | 27th Dec 17

    Surely right up my taste bud alley.
    Love the combo of all these flavors. Grandma’s know how to do it right for sure! Thanks for sharing!!

    • | 28th Dec 17

      Hi Marsha!
      Grandma always knew best and was a wiz in the kitchen! I sure do miss her and cherish our memories together. Thanks so much for stopping by. You always brighten my day! Happy New Year Friend!

  7. Eliza | 31st Dec 17

    My mom used to make this on the stove and I am so happy to find your variation for the oven! Cooked it with leftover Christmas ham and used frozen peas instead of canned, plus a little grated parmesan on the top. So delicious!!!!

    • | 1st Jan 18

      Hi Eliza!
      I love the addition of grated parmesan on top! I’m going to try that next time. Thanks so much for sharing with me. I love hearing how others change my recipes up to fit their individual tastes. It gives me great ideas. I hope you have a wonderful and happy New Year.
      Happy Nesting!

  8. Missy | 12th Oct 18

    My Mom used to make this with leftover roast beef. Only difference is hers was only 3 layers, chopped onion on the bottom, sliced roast beef on top of the onion and sliced potatoes on top of the beef. Add leftover homemade gravy or a can of beef gravy on top and bake. I probably do about half of your recipe but it could be doubled. Also good with leftover chicken or turkey with the corresponding gravy. It’s possible my Mom got the recipe from her Mom and it was called “Pack Supper”!

    • | 12th Oct 18

      I’m loving this recipe change up! I’m going to have to try it especially with left over roast beef. Yum! It would be great at Thanksgiving too with left over Turkey. Thank you so much for sharing this with me and my readers. Grandma’s and Mom’s have the best family recipes! I hope you have a great weekend!
      Happy Nesting!

    My house smells so good, casserole’s in the oven. Even though it’s 90 degrees and it’s Aug in Florida I’ll just drop the air down and pretend it’s January.

    • | 5th Sep 19

      Hi Carol!
      Some sacrifices have to be made in the name of food! lol I hope you liked the casserole…it’s truly one that holds a special place in my heart! Thanks for popping by…hope it cools down soon.
      Happy Nesting!
