Leftover Oatmeal: 10 Delicious Recipes To Help You Use It All Up!



It’s one of those super frugal breakfast meals that busy moms love to rely on. Quick, rolled, or steel cut- they’re all fair game in our home. I love to make a big pot of creamy oats, and sweeten it with brown sugar and cinnamon, or maple syrup, or homemade jam, or add bits of fruit and maybe some nuts.

I make oatmeal about twice a week, but I can never seem to get the proportions right. No matter how much I make, either I didn’t make enough or I make way too much. Some days my kids want three helpings, and some days they don’t want any. Are your kids like that, too?

Sometimes we’ll just reheat the leftovers the next morning or maybe have them for a snack, but usually there isn’t enough for all of the kids to split. It works out better to use the leftover oatmeal in an entirely different recipe. I’m all about stretching leftovers to get the most out of them!

Here are a few recipes to inspire you to save that little bit of oatmeal leftover in the bottom of the pot to make something new and tasty…

  1. I ended up making the Leftover oatmeal cookies. I was so excited to see the recipe (I work at a school and we have oatmeal for breakfast once a week and there are always leftovers). I jumped the gun and made them using oil instead of shortening (I had written down only the ingredients, not the method, in my excitement). They ended up tasting and looking like muffin cookies… the staff loved them, we are going to serve 4 different varieties for breakfast next week. (with raisins, chocolate chips, blueberries and shredded apples)Next time Ill try the recipe the right way!

  2. I just found this site. And saw the question about applesauce
    Yogurt is a much better substitute for shortening even using fat free yogurt.

    Can’t wait to try some of the recipes.

  3. I made these with cooked steel cut oats and they did
    Not turn out . They baked uomas round balls that were not done after 20 minutes in the oven. Will go back to my tried and true regular dried oats☹️

    • Steel cut are much more dense. Perhaps some leavening like baking powder or increased egg white may help with the consistency.

  4. Can I add mashed bananas to the cupcake recipe? Perhaps a bit more baking powder with help with the rising since the bananas may make it dense…

  5. Just tried the muffins this morning, I have a lot of left over (kids are tired of it). So I used 1 cup flour and 1 cup cooked oats. Cooked for 25 min because I used jumbo muffin tin. They turned out great. Might try and cut the sugar down a bit but still wonderful and the kids loved them 🙂 Thank You!

  6. I have new yeast that I used and the dough is not rising at all. I have kept the dough in a warmish place free of drafts??
    1 tsp sounds like very little yeast! to me!!

    • I tried this applesauce substitution a long time ago when I was on one of my silly college diets. The idea is that the pectin in the apples reduces the formation of gluten, which is what gives bread elasticity. I thought it tasted dreadful – made the results “jellylike” and with a weird sweetness. It changed the “chemistry” of the recipe. If you do try it, don’t substitute the whole quantity. Try half and half.

  7. My family eats oatmeal everyday and I’ve begun saving the last bits to use in sourdough breads and pastreis. I stumbled onto your blog and I’m so glad that I did! I’ve tried the oatmeal bread and the cookies. The cookies were wonderful! The oatmeal bread was also very good. I doubled the bread recipe and found that I needed almost 5 cups of flour for the 3 cups of cooked oatmeal. I made 2 heavenly loaves. I also added cinnamon and curants. I love your blog!

  8. Just wanted to drop by and let you know that the bread turned out AMAZING! It was so light and fluffy, yet dense enough for sandwiches, and the soft oat flavor was a nice departure from our usual bread. My whole family loved it! Thanks again for the recipe. 🙂

  9. I found my way here through Organic Authority when I was looking for something to do with our leftover breakfast oats! I decided on the Leftover Oatmeal Bread, and I can’t wait to make it. Thank you so much for the recipes!!! 🙂
