Best Oats for Baking

Before we dive into this lovely recipe, let’s talk oats. How do I know what kind is the best kind? There are so many to choose from, yet I chose good old-fashioned oats for this recipe. Why? They bake evenly, have a great texture, and a slightly nutty taste that really shines through when baked.

Quick oats can be used in a pinch, yet they will change the overall texture + not fluff up as nicely. So look for old-fashioned or ‘regular’ oats. Steel-cut oats won’t bake correctly for this recipe, plus they will taste off. I know a lot of people like steel-cut, yet I promise you won’t be disappointed with my oat choice in this baked oatmeal.

Baked Oatmeal Recipe

To take out a step in this recipe, buy already roasted (not salted) pecans. They lose some nutrients when they are pre-roasted, yet are still delicious. Then you can go straight to preheating + mixing up your ingredients.

Arrowroot powder can be swapped in for the baking powder. If you can’t have almond milk, then any kind of dairy free milk works great. Swap out oat flour with all purpose gluten free flour, or almond flour.

Mixing the flaxseed in with the wet ingredients helps turn it into a bonding agent. That’s why you want to let the wet ingredients sit for 5 minutes after mixing together.

To make a more streusel-like topping, mix melted coconut oil in a bowl with the pecans, maple sugar, and some cinnamon. Then spoon the mixture over top of the oatmeal mix in the pan before baking.

Easy Variations of Baked Oatmeal

If you want to cut back on the sugar in this recipe, then simply omit the sprinkled coconut sugar on top. Using green apples will also cut back on the natural sugar, making this a slightly tart recipe (which still tastes amazing!).

This can also be made with raspberries or blueberries in place of apples. Just know blueberries might create a bit more liquid at the end – think slightly syrupy finish.

Don’t be afraid to play with spices here too! Pumpkin spice would be a great variation, in place of just cinnamon.

  1. This was fantastic. No apples or applesauce on hand so substituted blueberries and cranberries and used olive oil instead of applesauce. Doubled the recipe for a large casserole dish. Everyone in the house enjoyed. Thanks!!

    1. Hey Grace – Great substitutions and improvising! Glad everyone enjoyed. 🙂

    I love oatmeal for breakfast, so I tried this today. It was easy, quick and would be great for a warm guest breakfast in the winter. I made two changes Almond Flour instead of Oat Flour, and I mixed unsweetened shredded coconut with 3 Tbsp of Demerara sugar. I thought it was awesome! Next time, I will use no sugar maple syrup and less sugar for topping. One question, will this freeze well?

    1. Hi Robert! We’ve not tried freezing this and think it might make the consistency less than desirable. Def let us know if you try it though!

    1. We add the pecans to the dish before it goes in the oven as a way to add some crunch and protein.

    2. Roasted pecans are added to the bottom of your baking dish prior to adding other ingredients. Def not a step to skip – it’s part of the yum factor for sure!

    1. Hey Kamisha! You can totally omit the coconut sugar in this recipe. You may want to consider adding additional maple syrup (either in the mix or drizzling at the end) or some chopped dates to compensate for the sweetness. Let us know what you try and how you like it!

    Delicious,! I used pears instead of apples since I had pears that needed to be used right away. Used half the amount of maple syrup. I think that raisins would be a good addition.
