- Effortless mornings: Dump everything in a bowl, bake, and boom—breakfast is ready while you sip your coffee.

Ingredients for Apple Walnut Baked Oats
Gather these simple ingredients – I bet most are already in your kitchen! The beauty of this recipe is how flexible it is while still delivering amazing flavor.
- 1 cup rolled oats (not instant – they get too mushy)
- 1 medium apple, diced (I leave the skin on for extra fiber)
- 1/4 cup chopped walnuts (toast them first if you’re feeling fancy)
- 1 cup milk (any kind works – I often use almond milk)
- 1 egg (or 1 tbsp ground flaxseed + 3 tbsp water for vegan)
- 1 tbsp honey or maple syrup (adjust to your sweet tooth)
- 1 tsp cinnamon (the more the merrier, I say!)
- 1/2 tsp vanilla extract (pure, not imitation)
- Pinch of salt (trust me, it makes all the flavors pop)
Ingredient Notes & Substitutions
Here’s my cheat sheet for making this recipe work with what you’ve got:
- Apples: Use whatever’s ripe! Fuji and Honeycrisp are my favorites for sweetness, but Granny Smith adds nice tartness.
- Sweetener: Swap honey for maple syrup, brown sugar, or even mashed banana if you’re out.
- Milk: Any dairy or plant milk works – just avoid anything too watery like coconut milk from a carton.
- Egg-free: Flax eggs work great, but skip chia seeds – they make the texture weird.
- Warning: Don’t sub quick oats – they absorb too much liquid and turn to glue!

How to Make Apple Walnut Baked Oats
Alright, let’s get baking! This recipe comes together so easily – even when I’m barely awake at 6am (you know how those mornings go). Here’s exactly how I do it:
- Heat things up: First, preheat your oven to 350°F (175°C). While that’s warming up, grab your favorite baking dish – I use an 8×8 inch one – and give it a good greasing with butter or cooking spray. Nobody wants stuck-on oats!
- Mix the dry stuff: In a big bowl, toss together your oats, diced apple (don’t forget to core it first!), walnuts, cinnamon, and that pinch of salt. Mix it all up with your hands – I love how the apples get coated in cinnamon!
- Whisk the wet ingredients: In another bowl, whisk together the milk, egg (or flax egg), honey, and vanilla until it’s all smooth and golden. Pro tip: warm the honey for 10 seconds if it’s too thick to mix easily.
- Bring it all together: Pour the wet mixture over the dry ingredients and stir gently until everything’s combined. Don’t overmix – a few lumps are totally fine. The batter should look thick but pourable.
- Bake to perfection: Pour your mixture into the prepared baking dish and pop it in the oven for 25-30 minutes. You’ll know it’s done when the edges are golden brown and the center looks set (no jiggling when you give the pan a little shake).
- The hardest part: Let it cool for about 5 minutes before digging in. I know, I know – the smell is irresistible, but this helps it set up properly so you get perfect slices.
Tips for Perfect Apple Walnut Baked Oats
A few of my hard-earned secrets for getting this just right every single time:
- Grease generously: Really coat that baking dish – oats love to stick!
- Toothpick test: Stick one in the center – it should come out mostly clean with maybe a few moist crumbs.
- Rest time matters: Those 5 minutes of cooling make all the difference in texture.
- Top shelf baking: For even browning, bake in the upper third of your oven.
- Size check: If doubling the recipe, use a 9×13 dish and add 5-10 extra minutes.
Serving Suggestions for Apple Walnut Baked Oats
Now for the fun part – dressing up your baked oats! My family goes wild for toppings. A dollop of Greek yogurt adds creamy tang, while extra walnuts give that perfect crunch. Drizzle with warm maple syrup if you’re feeling indulgent, or sprinkle with cinnamon for extra coziness. This pairs beautifully with a strong cup of coffee or chai tea – the spices complement each other so well. Honestly, I’ve even served it as dessert with a scoop of vanilla ice cream (don’t tell my kids it’s actually good for them!).
Storing and Reheating Apple Walnut Baked Oats
This baked oats recipe is a meal prep dream! Leftovers keep beautifully in the fridge for up to 3 days – just cover the dish tightly with plastic wrap or transfer to an airtight container. The texture actually improves as the oats absorb more of those delicious flavors overnight. To reheat, I usually go for the microwave (about 60-90 seconds per serving) when I’m in a hurry, but popping it back in the oven at 300°F for 10 minutes gives it that fresh-baked crispness. Fair warning – it’ll be slightly denser after refrigeration, but just as tasty!
Apple Walnut Baked Oats Nutritional Information
Here’s the scoop on what’s fueling your morning! One generous serving (about half the recipe) packs roughly 320 calories, with 12g of good fats from walnuts, 10g of protein to keep you full, and 45g of carbs for lasting energy. Of course, these numbers dance a bit depending on your exact ingredients – like whether you use whole milk or almond, extra honey or less. But no matter how you tweak it, you’re getting a breakfast that’s as nutritious as it is delicious!
FAQs About Apple Walnut Baked Oats
Can I use steel-cut oats?
Nope – they’re too tough for this recipe! Stick with old-fashioned rolled oats. Steel-cut oats need way more liquid and cooking time (trust me, I learned this the hard way with a tooth-breaking breakfast).
Is this freezer-friendly?
Absolutely! Bake, cool completely, then slice and freeze in airtight containers for up to 2 months. Reheat straight from frozen in the microwave (add 30 seconds) or oven. Perfect for grab-and-go breakfasts!
How do I make it vegan?
Easy peasy! Just swap the egg for a flax egg (1 tbsp ground flax + 3 tbsp water) and use maple syrup instead of honey. I make it vegan for my sister all the time – tastes just as amazing.
Can I add other fruits?
Oh yes – get creative! I often toss in a handful of raisins or dried cranberries. Fresh pears work beautifully too. Just keep the total fruit to about 1 cup so it doesn’t get soggy.
Why did mine turn out dry?
Probably overbaked or not enough liquid. Next time, check at 25 minutes and pull it when the center just barely jiggles. Also, measure your oats correctly – packed cups will absorb too much moisture.
