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.

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.

  • We used as a springboard for what was on hand and doubled it. Because cooking once to get 2 meals is a sanity saver! Had frozen pears, small handfuls of dried apricots and figs, plus a lone Cortland apple (the best baking apple in my opinion). Did 1/2 cup sugar. And a bag of pecans. The sweetness was just perfect.

  • Hi Jenn; what do you think about adding some cranberries to this? I have a half bag leftover. Thanks! Love your site.

  • Can this be made in individual servings- such as wide mouth canning jars or tartlet pans?

    • Hi Beth, Sure that should work (as long as you can put canning jars in the oven). Individual portions may not take as long to bake so keep a close eye on them. Hope you enjoy!

  • Is there a way to search comments? I want to see what changes others made with types of milk, fruit, frozen berries or not, sugar substitutes, and ways to eliminate – apples are already sweet. I do not drink cow’s milk and regularly make rice pudding with soy milk – so guess it would work here – but wondering if anyone tried dried buttermilk, soy, cow’s milk product, and how it was?

    • Hi Madeleine, unfortunately, there’s not a search function for the comments. You can use the find feature on your computer and type in a word that may take you to some comments that would be relevant to you. Regarding your questions: 1) I think a non-dairy milk would work here but wouldn’t recommend buttermilk. I haven’t tried this dish with anything but brown sugar, but I suspect the stevia/agave blend should work. I’d love to hear how it turns out! 2) If you want to use berries, I’d recommend this recipe instead (and frozen blueberries will work). 3) I haven’t tried this with a sugar substitute but I think it would work. Hope that helps!

  • I love love love this recipe! We live in NE Washington and it was 14 degrees this morning (it’s only mid November). Our winters are long and very cold and this baked oatmeal is our go to most mornings. It’s a perfect start to our day! I’ve taken a couple of liberties and used dried cranberries instead of raisins and sometimes add ground flax. Thank you!

      • Hi Darrin, You can just omit the nuts, but I wouldn’t recommend using the dried apples. Hope you enjoy if you make it!

  • We love baked oatmeal at my house. Another similar recipe calls for a 400 degree oven. . This recipe at 325, was not nearly ready after 55 minutes. I raised it to 370 to completely cook. Great taste!

  • This is delicious. It reminds me of bread pudding. This is the best baked oatmeal recipe that I have ever tried. Thank you for sharing!

  • I always enjoy your recipes but this one needed tweaking for me. I used half the sugar called for. I didn’t care for the texture. I am going to try mixing all ingredients together and letting it sit in the refrigerator overnight and then baking it. I liked that the oatmeal had added protein.

  • This tastes amazing! I skipped the raisins and only added 20 grams of sugar. The rosted walnuts on top are my favourite part.
