Breakfast & Brunch
This apple cinnamon steel cut oats recipe transforms simple oats into a comforting, spiced breakfast that tastes like autumn in a bowl. The secret lies in slow-cooking steel-cut oats with diced apples and cinnamon sticks, creating a naturally sweet, chewy texture that rivals any bakery treat.
I developed this version after years of experimenting with oatmeal textures—this one stays hearty and satisfying without turning mushy.
The magic happens when you simmer the oats with warm spices and fresh apple pieces, allowing their natural sugars to caramelize slightly. Unlike quick oats, steel-cut grains absorb liquid gradually, delivering that perfect chewy bite while staying tender.
We’re using plant-based milk by default, but you can easily swap in dairy for creamier results. This recipe is designed to be your go-to morning routine—minimal prep, maximum flavor.
By the time you’re done, you’ll have a spiced apple oatmeal with deep cinnamon warmth, subtle apple sweetness, and a texture that’s neither too soft nor too firm. The aroma alone will have your kitchen smelling like a cozy café.
Top with toasted nuts, a drizzle of maple syrup, or a dollop of coconut yogurt for extra richness. Perfect for meal prep or a lazy weekend brunch.
What makes this recipe stand out is its versatility—use it as a base for savory variations (like adding smoked paprika) or keep it sweet with extra fruit and spices.
The vegan-friendly foundation means everyone at the table can enjoy it, while the slow-cooked method ensures every bite is packed with flavor. Let’s get cooking!
Ingredients for apple cinnamon steel cut oats
Pantry staples plus a few fresh touches—this vegan oatmeal tastes like autumn in every bite.
| Ingredient | Amount | Notes |
|---|---|---|
| Steel Cut Oats 🌾 | 1 cup | Old-fashioned or Irish oats preferred |
| Granny Smith Apples 🍎 | 1 ½ cups | Diced, skin on for texture |
| Cinnamon Sticks 🌿 | 2 whole | Or 1 tbsp ground cinnamon |
| Unsweetened Almond Milk 🥛 | 2 ½ cups | Or any plant-based milk |
| Maple Syrup 🍯 | ¼ cup | Grade B for richer flavor |
| Ground Cinnamon 🌶️ | 1 tbsp | Plus extra for garnish |
| Vanilla Extract 🥫 | ½ tsp | Pure alcohol-free preferred |
| Salt 🧂 | ¼ tsp | Kosher or sea salt |
| Toasted Walnuts 🥜 | ¼ cup | Chopped for topping |
| Coconut Yogurt 🥥 | ¼ cup | For vegan creaminess |
| Lemon Juice 🍋 | 1 tsp | Freshly squeezed |
| Ground Nutmeg 🌿 | ⅛ tsp | Freshly grated preferred |
| Coconut Oil 🫒 | ½ tbsp | For toasting oats |
The apples are the star here. Granny Smiths stay crisp when diced, but Fuji or Honeycrisp work too—just toss them in lemon juice to prevent browning. I grab mine from the produce section at Whole Foods when they're in season, but any grocery store has them year-round. For the oats, Bob's Red Mill steel cut is my go-to, but any old-fashioned oats will do. The cinnamon sticks? Splurge on Ceylon cinnamon if you can—it's milder and more aromatic than regular cassia. Toast them lightly in a dry pan for 30 seconds before adding to the pot for extra depth of flavor.
No almond milk? Oat or soy milk works just as well—just check the carton for added sugars. Short on maple syrup? Agave or date syrup gives a similar sweetness, though maple's caramel notes are unmatched. Want more warmth? Add a pinch of cardamom or allspice. The walnuts can be swapped for pecans or almonds, and if you're feeling fancy, toast them in the same coconut oil you use for the oats. For the yogurt, So Delicious coconut yogurt is my favorite—it's thick and creamy without any weird aftertaste. If you can't find it, Kite Hill almond yogurt is a solid backup.
This keeps beautifully for 4 days in the fridge—the flavors actually deepen overnight. Portion into jars with the toppings on top so they stay fresh. Freezes for 3 months if you want to make a big batch for the week. Pro tip: Reheat with a splash of milk or water to restore creaminess. The cinnamon sticks can be reused for up to 3 batches—just save them in a jar until they're too crumbly. Store the walnuts in the freezer to keep them crisp.

- Taste Like a Bakery: Between us, the cinnamon sticks simmering in the almond milk make this smell like a spice shop exploded—and that’s before the apples get tossed in.

Step-by-step instructions for apple cinnamon steel cut oats
Let's make these hearty oats with a perfect chewy texture and warm spice swirls.
Toast the Steel Cut Oats for Rich Flavor
Heat a medium saucepan over medium heat and add the 0.5 tablespoon coconut oil. Once the oil shimmers, add the 1 cup steel cut oats and stir constantly for 2-3 minutes until they turn a deeper golden color and smell nutty. This toasting step develops deeper flavor and prevents the oats from becoming mushy.
Watch carefully—they're done when they're fragrant and slightly darker than their original color. Remove from heat immediately to prevent burning. This quick step makes all the difference in texture and taste, so don't skip it.
Simmer with Apples and Cinnamon Sticks
In the same saucepan, add the 2.5 cups unsweetened almond milk, 1.5 cups diced Granny Smith apples, 2 whole cinnamon sticks, and 0.25 teaspoon salt. Stir well to combine, then bring to a gentle boil over medium-high heat. Once boiling, reduce heat to low and cover with a tight-fitting lid.
Let the mixture simmer for 25-30 minutes, stirring occasionally, until the oats are tender but still have a slight bite. The apples should soften but retain some texture—you want them to break down just enough to release their juices and sweetness. The cinnamon sticks will infuse the liquid with their warm aroma, creating that signature apple cinnamon flavor.
Finish with Sweet and Tangy Touches
Remove the saucepan from heat and stir in the 0.25 cup maple syrup, 0.5 teaspoon vanilla extract, 1 teaspoon lemon juice, and 0.125 teaspoon ground nutmeg. Let the mixture sit for 5 minutes to allow the flavors to meld together. The lemon juice brightens the sweetness while the nutmeg adds a subtle warmth that complements the cinnamon.
Taste and adjust seasoning if needed—you might want to add more maple syrup for sweetness or a pinch more salt to balance the flavors. The oats should be creamy but still have some texture, with the apples nicely incorporated throughout.
Serve Warm with Toppings
Divide the oats into four bowls, then top each serving with 1 tablespoon ground cinnamon, 1 tablespoon toasted walnuts, and 1 tablespoon coconut yogurt. The cinnamon adds an extra layer of warmth, the walnuts provide crunch, and the coconut yogurt gives a creamy, tangy contrast to the sweet oats.
Let the oats sit for 2 minutes before serving so the toppings can soak up some of the flavorful liquid. The combination of textures—chewy oats, tender apples, crunchy walnuts, and creamy yogurt—makes this a satisfying breakfast that feels indulgent yet nourishing.
Pro Tips For Making Apple Cinnamon Steel Cut Oats
- Toast the Oats First: I used to skip this, but toasting steel cut oats in a dry pot for 2-3 minutes over medium heat before adding liquid makes them chewier and deeper in flavor—like the difference between dry toast and soggy bread. (Yes, even if you're impatient like me, don’t rush this.)
- Peel and Dice Apples: Granny Smiths stay crispy when you peel and dice them small (about ¼-inch cubes) before adding them to the pot. Whole slices turn mushy, and unpeeled skin can make the texture uneven. Do this right after cutting the oats—no waiting.
- Simmer, Don’t Boil: Steel cut oats need low heat and patience. After adding liquid, reduce to a gentle simmer (tiny bubbles, not rolling) and stir once. Boiling them turns them gluey, and you’ll end up with a porridge instead of a hearty breakfast.
- Use Two Cinnamon Sticks: One stick is polite; two are what you actually taste. Break a second stick in half and add it with the apples—they’ll infuse the milk with warmth without overpowering. Remove them before serving, or you’ll chew on wood. (Trust me, it’s a vibe killer.)
Perfect pairings for these flavors
Spiced Apple Compote
Transform leftover diced apples into a warm apple compote by simmering them with 2 tbsp maple syrup, ½ tsp cinnamon, and ¼ tsp cardamom for 10 minutes.
This thick, jam-like topping takes your oats to the next level—drizzle it generously over the top or mix it directly into the oats for extra depth. 🍏
Crunchy Nut Mix
Toast a mix of walnuts, pecans, and almonds in 1 tbsp coconut oil with a pinch of salt until golden. Toss with ½ tsp cinnamon and ¼ tsp cayenne for a spicy-sweet crunch.
Store in an airtight container for up to 2 weeks—it’s perfect for yogurt bowls, salads, or oatmeal. 🥜
Creamy Yogurt Swirl
Mix ½ cup coconut yogurt with 1 tbsp maple syrup and ½ tsp vanilla extract. Swirl it into individual servings of oats just before eating for a creamy, tangy contrast. For extra richness, fold in 1 tbsp almond butter or a sprinkle of chia seeds. 🥥
Warm Spiced Milk
Heat 1 cup almond milk with ½ tsp cinnamon, ¼ tsp nutmeg, and a pinch of salt until steaming. Pour it over your oats for a cozy, latte-like experience—the warmth enhances the apple and cinnamon flavors beautifully. 🌿
Sweet-Tart Fruit Pairings
Balance the richness with bright, tangy fruits like sliced pear, kiwi, or orange segments. Their acidity cuts through the sweetness, making each bite feel fresh. Serve with a sprinkle of flaky sea salt to highlight the natural flavors. 🍊
Herbal Tea Pairings
Sip on chamomile, rooibos, or spiced chai tea alongside your oats—their earthy, floral notes complement the cinnamon and apple perfectly. For a cozy vibe, add a cinnamon stick to your tea for an aromatic twist. ☕

Frequently asked questions
Why do steel cut oats need toasting?
Toasting the oats first develops deeper, nuttier flavors and prevents them from becoming mushy during cooking. The 2-3 minute toasting step in coconut oil creates that perfect chewy texture while adding a subtle richness. Skipping this step often results in oats that turn too soft or gummy.
Can I make this recipe with regular rolled oats?
Yes, but the texture will be different. Rolled oats cook faster (10-15 minutes) and become softer, almost porridge-like. For a similar chewy texture, use thick-cut oats (like Scottish oats) instead. The cooking time will be closer to steel cut oats but slightly shorter.
How do I prevent the apples from turning brown?
Toss the diced apples with 1 teaspoon lemon juice immediately after cutting. This prevents browning by inhibiting oxidation. For extra insurance, sprinkle with ¼ teaspoon ground cinnamon—it also enhances flavor while keeping the apples looking fresh.
What's the best way to reheat leftovers?
Add 2-3 tablespoons of water or milk per serving and heat gently in a saucepan over low heat for 3-5 minutes, stirring often. Microwaving can make steel cut oats rubbery. For best results, reheat only what you need to eat immediately.
Can I make this gluten-free?
This recipe is naturally gluten-free as long as you use certified gluten-free steel cut oats and check your other ingredients (like maple syrup and coconut yogurt). Always verify labels, especially for oats which are often processed in gluten-containing facilities.
