As always, you can find the full recipe, with ingredient amounts, detailed instructions, and tips in the recipe card below!

- Serve & Store. Enjoy warm with a drizzle of maple syrup and milk. Store leftovers covered (or in an airtight container) in the fridge 2-3 days. When reheating leftovers, you’ll likely want to add a splash of milk.
FAQ + Tips For The Best Apple Cinnamon Baked Oatmeal
What the heck is a chia egg? A chia “egg” is a vegan egg substitute made from chia seeds and water. Chia seeds expand and “gel” when they’re mixed with liquid, and in this recipe, the chia “egg” is used as a binder and gives the oatmeal part of it’s texture. You can use a flax egg (swap ground flax for the chia seeds and use the same ratios) or powdered egg substitute (follow your package direction) if you prefer, or if you don’t have an issue with regular eggs, you can totally go that route.
Can I substitute steel cut oats or quick oats? No. I LOVE steel cut oats and cook them all the time, but they don’t work in this recipe. They don’t have enough liquid or time to soften and typically burn before they’re cooked through. So what you’re left with is a dry, crunchy mess. I don’t recommend them. Similarly, I don’t recommend quick oats because they can easily get mushy. Rolled oats seem to be the sweet spot.
Gluten Free Notes – Oats themselves doesn’t contain wheat gluten, but are often farmed and processed in a way that cause cross-contamination. If you’re avoiding gluten, be sure to buy certified gluten free oats. We like Bob’s Red Mill or Trader Joe’s brands.
Nut Free? You can totally omit the pecans, or add additional apples or some raisins. You can also use any milk you like here–whatever you drink!

Question: could you prepare this in the pan the night before, refrigerate it overnight and then bake in the morning?
Caitlyn – I haven’t tried it this way yet, but I think you could. The only thing you’ll want to watch for is dryness. The oats will absorb liquid overnight, so there may not be as much residual liquid in the pan. If yours is looking a bit dry/soaked in in the morning, you may want to add a splash more of milk so it doesn’t bake up dry 🙂
If you give it a try, I’d LOVE to know how it turns out for you!
My favourite baked oatmeal recipe before I went vegan contained maple syrup in the batter and I liked the sweetness. If I added 3-4 tablespoons in the bake do you think that would mess with the recipe too much?
Not at all! That sounds delicious!
