Amish-Style Baked Oatmeal with Apples, Raisins and Walnuts

Tested & Perfected Recipes

This baked oatmeal transforms ordinary oatmeal into something special with fruit, nuts and a lightly sweetened custard.

Baked oatmeal is a traditional and comforting Amish breakfast casserole. Unlike regular oatmeal, which is made on the stove-top and has a porridge-like consistency, baked oatmeal is made in the oven and has a consistency similar to bread pudding.

There are endless variations — the recipe is easily adapted with whatever fruits and nuts you have on hand — but this version filled with tart apples and plump raisins with a crunchy walnut topping is my favorite.  Bonus: it can be made ahead of time and it reheats beautifully. 

What you’ll need to make baked oatmeal

ingredients

How to make it

Begin by combining the oats, half of the nuts, raisins, brown sugar, baking powder, salt and cinnamon in a bowl.

Top with the oat mixture and sprinkle remaining walnuts over top.

Bake for about 40 minutes, until the oats are set and the top is golden. Be sure to save some leftovers; oddly, this dish is just as delicious — if not more so — cold out of the refrigerator the next day.

  • This recipe is amazing! I made it using pecans since that is what I had at the time- it turned out so delicious. My husband loved it too and this recipe will be a keeper! One that we make again and again!

  • I have made the following changes. Exclude butter and use a piece of parchment paper to line the pan. Replace the cows milk with oat milk. Replace the eggs with 2 tbs flax meal. Replace the brown sugar with real maple syrup. Super yummy! I make a batch at the start of the week. Sometimes I do apples and pecans. Sometimes blueberries (frozen – really easy).

  • Really really delicious! I only used 2 TBSP of brown sugar. Added 1 extra apple, so 3 in total. Will definitely make it again!

  • I’d love to know if anyone has tried to, or could advise on, using overnight-soaked steel cuts oats instead. My thinking is that I’d have to pre-cook them to about 50% doneness before combining into the casserole…?

    • There’s a baked oatmeal recipe using steel cut oats on the “Alexandra’s Kitchen.com” cooking blog. I believe that she uses steel cut oats right out of the package.

  • I’ve tried this twice with different fruit combinations and it is a winner. Leftovers are great! Made once as written and once with blueberries and peaches. I really cut back the sugar—used 1/4 c. the first time and 2T the second, didn’t miss it at all. Also cut the raisins and nuts in half the second time to lower the calories—still delicious!

  • This is a wonderful recipe. Can’t wait to have the leftovers tomorrow. The first time I made it, I didn’t have raisins and didn’t want to venture out with COVID worries so I substituted quartered grapes for the raisins and they were great.

  • I enjoyed this recipe! I plan to serve this for a Christmas breakfast take-away for our church members (mostly older and stuck at home) using pears and dried cranberries. I would like to bake it in 9 x 13″ pans. Should I use 1 1/2 recipe for a 9 X 13 ” pan or two recipes? How many servings should be cut from each pan? I was hoping to cut 12 servings but…if I double the recipe the servings would be thicker. Does that matter? I plan to bake it soon, cut it in servings and wrap individual pieces, then freeze each serving. On Christmas eve day folks would pick up (or they will be delivered) the “boxes” with the frozen piece and reheat it Christmas Day. Suggestions for directions for reheating in the microwave? We have considered adding a snack bag with three sausage links for reheating, Or ham? or pre-cooked bacon?
    Any suggestions would be so appreciated!

    • Sure, Virginia, How nice that you’re doing that! I would double this and bake it in a 9 x 13 dish. It will be a bit thicker so you may need to add just a few minutes to the baking time. To reheat, they can just pop their piece into the microwave and heat on high for about 90 seconds or until hot in the center. Hope everyone enjoys! Regarding some sort of pork option, the only thing that comes to mind (from my recipes) is this candied bacon. Full disclosure — this is definitely best if eaten shortly after it’s made as if made ahead it will lose its crispiness.

      • Thanks so much for your encouragement! And for responding so quickly! I will include the microwave directions. Do you think I could cut it (a double recipe baked in a 9 x 13 pan) in 12 pieces? I’m also toying with the idea of baking it in the jumbo muffin tins (using liners), and freezing them in sandwich bags. I have pears that are ripe so will experiment with the jumbo muffin pan today.
        I will explore the candied bacon!
        I am excited to put some time and energy into this project as I think they will be delighted to open the “gift”.

  • Delicious! I didn’t have raisins, so I chopped up some unsweetened dates and substituted pecans for the walnuts. Was just a little too sweet for me. Very versatile recipe that tolerates tweaks. The second time I switched out the apples for shredded carrots – it tasted like carrot cake. I plan to make a version of this recipe weekly – it’s that good!

  • I have made this recipes for a couple of years and its always turned out perfect… whether I use apples, blueberries or blackberries. I do cut the sugar to 1/3 cup and then if I need to sweeten it a bit when eating I add add a smidgen of maple syrup (or a tad more!) Cold or warm … I can eat it any way! Thank you for your delicious and easy to make recipes.

  • We continue to serve this oatmeal as a weekly special at Ober Easy Diner. Its such a unique way to serve oatmeal — our customers just can’t get enough of it. This is incredibly simply to make — you have to give it a try, especially with the cool fall mornings upon us! We also mix it up on occasion and serve the blueberry baked oatmeal — that too makes for a wonderful breakfast!

    Jenn is well known to all at the Diner as many of her recipes are made weekly and fill our bakery and desert display. Maybe someday we can get Jenn to come out to NH and visit!

    I have not found another site that comes close to matching the breadth of recipes, clear instructions, and great presentation that I have come accustomed to with Jenn’s onceuponachef site!

    Jenn thank you so much for all of the great recipe’s our customers are thankful as well.

    BTW, this weekend I am making your bourbon pecan pie for the restaurant — I can’t wait to make it — it looks like a blast and can’t wait to taste it!

    • I couldn’t agree more with you Tim! I run a B&B and make Jenn’s recipes all the time, and they’re always a huge hit with the guests! If you haven’t tried it yet, I would highly recommend her Baked apple french toast. It’s just incredible, and such a nice dish to serve in the fall.

      Thank you Jenn for all the wonderful recipes!

  • I made this but used dried cherries instead of raisins and pecans rather than walnuts. the cherries added an incredible burst of flavor. This will definitely be a go to favorite. It was brought to a breakfast covered dish and lots of recipe requests were received.

  • This recipe is everything I hoped it would be! The flavor and texture are wonderful. I didn’t have quite enough rolled oats so I had to use half instant oats, but it turned out just fine. There’s loads of oatmeal and isn’t super-sweet so it doesn’t taste like a dessert. It’s exactly what I wanted. Restraining myself from eating the entire thing is proving very difficult.
