Apple crisp for breakfast is something I fully believe in and these apple crisp baked oats are my favorite way to make it happen. All the cozy fall flavors of a warm apple crisp — gooey cinnamon apples, warm spices, that soft hearty oat base — in a nourishing breakfast that is naturally sweetened with maple syrup and packed with protein from greek yogurt and egg. It tastes like dessert for breakfast in the best possible way and it is genuinely one of my most looked forward to fall morning meals.

Baked oats in general are a complete game changer for meal prep and this version specifically is one I make on repeat every fall from the first week of September straight through November. The oat mixture comes together in one bowl, the cinnamon apples get folded right in, and the whole thing bakes in about thirty minutes into something that slices cleanly into portions and reheats beautifully all week long. Make it Sunday evening, slice it into squares, and Monday through Friday morning is handled before you have even had your coffee.

The greek yogurt in the oat base is the addition that makes these baked oats so much more filling and nourishing than a standard overnight oat situation. Combined with a whole egg it creates this custardy, almost cake-like texture that holds together perfectly and keeps you genuinely satisfied all morning long. Maple syrup is the only sweetener in the entire recipe and the cinnamon apples bring so much natural sweetness that you really do not need anything more. Every ingredient is earning its place.

The cinnamon apple layer is where the magic really happens. Diced apples tossed in cinnamon, maple syrup, and a little butter and cooked down just enough so they are tender and gooey and fragrant before they fold into the oat mixture. They soften further as everything bakes together and the result is little pockets of warm cinnamon apple in every single bite. This is the fall breakfast recipe you will make every year and look forward to every single time.

Why You’ll Love This Recipe:

The gooey cinnamon apple layer folded throughout the oat base means every single slice has warm spiced apple in every bite rather than just a thin layer sitting on top
Greek yogurt and egg in the oat base add enough protein to make this a genuinely filling and nourishing breakfast that keeps you satisfied all morning long
This is one of the most meal prep friendly breakfast recipes on the blog because it bakes on Sunday and gives you perfectly portioned nourishing breakfasts ready to reheat all week without any additional effort
The whole thing is naturally sweetened with only maple syrup which means it tastes indulgent and satisfying without any refined sugar anywhere in the recipe

Key Ingredients:

Rolled oats: The hearty, filling base that gives the baked oats their structure and that satisfying chewy texture. Old fashioned rolled oats are strongly recommended over quick oats which will give you a mushier, less defined texture after baking
Greek yogurt: Adds creaminess, protein, and a subtle tang to the oat base that makes these baked oats so much more satisfying than a standard overnight oat situation. It also contributes to that soft, almost custardy texture that makes every slice so good
Maple syrup: The only sweetener in the entire recipe doing all the sweetening work for both the oat base and the cinnamon apple layer. It adds a warm, caramelized depth that white sugar simply cannot replicate
Honey crisp apples: The best apple for this recipe because they hold their shape during cooking and have that perfect sweet-tart balance that pairs so beautifully with the warm cinnamon in both the apple layer and the oat base. Granny Smith is a great swap for more tartness
Cinnamon: Running through both the oat base and the cinnamon apple layer so the warm spice ties every component together and makes this taste like apple crisp in breakfast form
Coconut oil: Adds richness and moisture to the oat base and helps the top of the baked oats get slightly golden as it bakes for that beautiful finished look when it comes out of the oven

Tips for Success:

Cook the cinnamon apples down before folding them into the oat mixture so they are tender and the excess moisture has cooked off. Raw apples folded into the batter release too much moisture during baking and can make the oats dense and wet
Press the oat mixture firmly and evenly into the baking dish so it bakes uniformly and slices cleanly into portions without crumbling apart
Let the baked oats cool for at least fifteen minutes before slicing so they have time to set and firm up into portions that hold together. Slicing too soon results in crumbling edges
Add a drizzle of extra maple syrup and a sprinkle of cinnamon on top before baking for a beautiful golden finish and a little extra sweetness on the top layer

Storage:

Store apple crisp baked oats covered tightly or in an airtight container in the refrigerator for up to five days. Slice into individual portions before storing for the easiest grab and go breakfast situation all week. Reheat individual slices in the microwave for sixty to ninety seconds until warmed through or in a 350 degree toaster oven for eight to ten minutes. Add a fresh drizzle of maple syrup after reheating to refresh the flavor. These also freeze well for up to two months. Wrap individual portions in plastic wrap and store in a freezer bag. Thaw overnight in the refrigerator before reheating.

FAQ:

Can I use a different fruit instead of apples?
Absolutely. Pears work beautifully with the same cinnamon spice combination and have a similar texture that holds up well during baking. Blueberries, peaches, and cherries are all delicious variations that work with the same oat base. Adjust the sweetness of the fruit layer based on how sweet or tart your chosen fruit is since different fruits vary quite a bit in natural sugar content.

Can I make this dairy free?
Yes. Swap the greek yogurt for a dairy free coconut yogurt alternative and use a plant based milk in place of regular milk. The texture will be slightly different but still delicious and completely satisfying. Make sure the dairy free yogurt you use is thick and not too watery so the baked oats hold together properly after baking.

Is this recipe gluten free?
It can be made gluten free by using certified gluten free rolled oats which are widely available at most grocery stores. All other ingredients in this recipe are naturally gluten free so the oats are the only substitution needed for a fully gluten free version.
