Steel-Cut Oats vs. Rolled Oats
Oats are just oats, right? Not quite! The difference between steel-cut oats and rolled oats comes down to how they’re processed, and it makes a big impact on texture, cooking time, and flavor for overnight oats.
- Steel-Cut Oats: These are the least processed form of oats. The oat grains are chopped into coarse pieces with steel blades, giving them a hearty, chewy texture. Their nutty flavor and firm bite make them perfect for soaking overnight and not getting too mushy!
- Rolled Oats: Also called old-fashioned oats, these are steamed and flattened with rollers to create thin, soft flakes.
For this recipe, we’re using steel-cut oats for that extra chewiness and hearty bite. But if you only have rolled oats on hand, no worries—they’ll still make a delicious bowl of overnight oats!

What You Need for Overnight Steel Cut Oats
- Quick steel-cut oats – the tiny but mighty steel-cut oats soak up all the other goodness overnight, giving you a chewy, hearty base that’ll keep you full and happy till lunch. No cooking required—just a little patience!
- Unsweetened coconut or almond milk – your liquid gold! This dreamy addition softens the oats while adding a subtle creaminess. Coconut milk brings a slightly floral vibe, almond milk is light and nutty, and regular milk keeps it classic.
- Walnuts – toasted to perfection, these crunchy additions provide a nutty bite. Cinnamon – a warm hug; cinnamon just ties it all together.
- Chia seeds – these tiny powerhouses thicken your oats into a luscious pudding-like texture while sneaking in some extra nutrients.
- Natural honey – a drizzle of liquid sunshine! Acting as a natural sweetener, honey balances the tangy apple and earthy oats, making every bite a little sweeter.
- Honeycrisp apple – crisp, juicy wedges of apple add a fresh crunch and a sweet-tart zing. Go with Honeycrisp for that perfect snap, or mix it up with your personal favorite variety!

Step 2: Add honey, cinnamon, and chia seeds. Stir again. Add ¼ cup toasted walnuts and stir.
Step 3: Cover and store overnight in the fridge (or at least 6 hours).
Step 4: In the morning, cut up the apple, place slices in a small bowl, and sprinkle with ¼ teaspoon cinnamon. Microwave for 15 seconds and stir so cinnamon coats the apples.

More Fun Topping Ideas
Want to spice up your overnight oats even more? The toppings are where the real magic happens! Here are some more ideas to try when you’re not feeling cinnamon and apples:

- Dried Fruit: Think raisins, cranberries, or chopped dates for a chewy, sweet pop.
- Dark Chocolate Chips: Because chocolate for breakfast is always a good idea!
- Yogurt Swirl: Add a dollop of yogurt for creaminess and a tangy twist.
- Fresh Berries: Strawberries, blueberries, or raspberries bring a burst of color and juicy sweetness.
