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.

dry-ingredients

In a separate bowl, make the custard by whisking together the eggs, milk, and vanilla.

wet-ingredients

Combine the custard with oat mixture and melted butter.

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

ready-to-bake

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.

    A question for you- I want to make a lot of these recipes for a party and would like to bake this in those tin foil baking pans. Do you recommend changing the baking time or anything else in the recipe? Thank you!

  • Great staple recipe to build upon!
    I let the oat mixture sit for about 30 minutes prior to pouring into the baking dish. Instead of apples, I threw blackberries and blueberries into the mixture. As for the nuts, I chose sliced almonds & chopped walnuts.
    Additonally, I made a “crumble” topping. I wanted my dish to have a bit of crisp texture to it!
    Crumble Topping:
    In a separate bowl, I combined 3/4 cups of oats, 1/2 cup of brown sugar, 1/2 cup flour & 1/2 cup butter.
    Layers:
    Berries on the bottom, filled pan with the wet oat mixture, added top layer with the crumble topping recipe, then lastly added a handful of blackberries, almonds & raw sugar to the very top 🙂
    Thank you for this amazing recipe. I can’t wait to add different & fun ingredients to each batch! This dish is a new family favorite! So yummy 😋

  • This was a big hit at our house. I increased it by half again and used a 9×13 pan. To speed things up a bit I microwaved the apples in the bottom of a glass baking pan for several minutes. It baked in half and hour. Got the fishermen out onto the lake a bit faster…

  • I’ve made this as directed and it is GLORIOUS. That said, I have a couple of family members who will be visiting soon who can’t do soy, dairy, or gluten. Oats are naturally gluten-free, I think, but is it a big deal to sub out coconut milk or almond milk in the custard…? Thanks so much for this beautiful recipe!

  • My family loves this recipe. We also use a bit less sugar and it still tastes amazing.

    Question- I have read that some people make ahead and reheat and others make the night before and bake in the morning. I am wondering if there is much difference in end result. We are going on a family vacation and I am planning this for our first morning. Should I make, bake and reheat or wait and put it all together the night before and bake in the morning? How long before baking can it sit in a fridge? It would be easiest to make in full and just reheat but my family loves this recipe so much so want it to turn out well. Any advice appreciated. Thanks!

    • Hi Nicole, glad you all like this! I truly think you can go either way in terms of making it ahead, but I’d probably just fully assemble it, let it sit overnight in the fridge overnight, and bake it in the morning. Hope you have a great vacation!

  • I’ve made this at least a dozen times and I just have to comment again that it’s SO tasty! Everyone who tastes this loves it. I do think you can reduce the sugar to 1/2 a cup and it’s still sweet enough to feel like a treat. The first time I made this my husband thanked me for giving him dessert for breakfast. I went through a phase where I used three apples rather than two because I wanted it more “appley”. Going back to two cups because I think it’s the best balance of ingredients. Also I love walnuts but for this dish pecans are just perfect. This is amazing with vanilla or plain yogurt scooped on top.

  • Just like banana bread is your solution for old bananas, this is the recipe I make when I have extra apples. I’ve tried multiple variations with different nut combination, but I find as written the best. I’ll often bake the night before and steal a small amount with ice cream (its delicious) and then reheat for breakfasts throughout the week.

  • I made this before reading the reviews; my sister lives in Lancaster, PA, and Amish oatmeal is available at all the local markets and stores. Loving it when I ate it there, I tried Jen’s recipe–excellent! Of course, I now know after reading the reviews that I could cut down on the sugar with no ill-effect–as well as substitute different fruits as well. I followed the recipe exactly and my son and I (my husband isn’t an oatmeal guy) ate it all week for breakfast. Easy to just scoop out a portion, nuke it, and you have instant, excellent breakfast!

  • I double this recipe for a 9×13 pan and make it twice a month. It is my husband’s favorite breakfast and often requests it. I like to take it out slightly before it is set to give it a custard texture and flavor. I love to eat it cold with some milk as it reminds me a little bit of rice pudding. This is a winner in our family!

  • I have made this recipe many times and recommended it to others many times. Sometime we use apples, sometime it is blueberries omitting the raisins. It is delicious whatever fruit is used. It works fine to also freeze it before baking, then bake from the frozen state. I put it in a freezer to oven dish wrapped tightly in foil. I add a few minutes to the baking time.

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!

  • 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”.

What an intriguing switch—carrots for apples! I might just try the entire combo for a carrot cake version.

  • 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.

  • 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.
