Ingredients List

High fiber apple cinnamon oatmeal starts with simple, wholesome ingredients that work together to create a balanced and satisfying breakfast. Here’s what you’ll need:

For the Oatmeal Base:
2 cups old-fashioned rolled oats (certified gluten-free if needed)
4 cups water or milk of choice (I often use unsweetened almond milk)
1 large apple, diced (I prefer Honeycrisp or Granny Smith for their texture)
2 tablespoons pure maple syrup or honey
1 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg (optional but lovely)
Pinch of salt

For Extra Fiber & Protein Boost:
2 tablespoons chia seeds or ground flaxseed
1/4 cup chopped walnuts or pecans
1 scoop vanilla protein powder (optional, but great for staying power)

Smart Substitutions:
If you’re out of maple syrup, brown sugar works beautifully
Swap apples for pears when they’re in season
Use quick oats if that’s what you have—just reduce cooking time by a few minutes
For a nut-free version, substitute sunflower seeds or pumpkin seeds
Dairy-free? Stick with water or plant-based milk as mentioned

The beauty of this high fiber apple cinnamon oatmeal is how forgiving it is. Don’t have chia seeds? No problem. The oats and apples alone provide plenty of fiber to keep you satisfied. This flexibility makes it one of my favorite easy overnight oats recipes to customize based on what’s in my pantry.

Timing

Prep time: 5 minutes
Cook time: 10-15 minutes
Total time: 15-20 minutes

Compared to many complicated breakfast options, this high fiber apple cinnamon oatmeal comes together in about the time it takes to brew your morning coffee. The hands-on time is minimal—mostly just chopping the apple and measuring ingredients. If you opt for the overnight oats version, the active time drops to just 5 minutes since the refrigerator does all the work while you sleep.

Step-by-Step Instructions

Making perfect high fiber apple cinnamon oatmeal is straightforward, but a few simple techniques ensure maximum flavor and ideal texture every time.

Prepare Your Apples
Start by washing and dicing your apple. I rarely peel mine—the skin adds extra fiber and nutrients. If you prefer a smoother texture or are making this for young children, peeling is fine. The diced apples should be about 1/2-inch pieces so they cook through but still retain some texture.

Combine and Cook
In a medium saucepan, combine the oats, liquid, diced apple, cinnamon, nutmeg, and salt. Bring to a gentle boil over medium heat, then reduce to a simmer. Cook for 8-12 minutes, stirring occasionally, until the oats are tender and the liquid is mostly absorbed. The apples should be soft but not mushy.

Pro tip: Don’t walk away during the last few minutes of cooking! Oatmeal can go from perfectly creamy to stuck-on-the-bottom in moments. Stay nearby and give it an occasional stir.

Finish and Sweeten
Remove from heat and stir in the maple syrup, chia seeds or flaxseed, and protein powder if using. Let it sit for 2-3 minutes—this allows the oats to thicken further and the chia seeds to gel, creating that lovely creamy texture.

For Overnight Oats In A Jar Variation
If you prefer breakfast overnight oats, simply combine all ingredients (except protein powder) in a jar or container, stir well, cover, and refrigerate overnight. In the morning, stir in protein powder if desired and enjoy cold or gently warmed. This method is perfect for blended overnight oats too—just pulse in a blender until smooth.

Nutritional Information

One serving of this high fiber apple cinnamon oatmeal (without optional protein powder) contains approximately:
Calories: 280
Protein: 8g
Carbohydrates: 48g
Fiber: 9g
Sugar: 18g (mostly natural from apples and maple syrup)
Fat: 7g

The nutritional profile makes this an excellent choice among healthy breakfast recipes. The combination of complex carbohydrates from the oats and natural sugars from the apples provides sustained energy, while the significant fiber content (about one-third of your daily needs) supports digestive health and helps you feel full longer. The addition of chia seeds or flaxseed boosts omega-3 fatty acids, and walnuts contribute heart-healthy fats.

Equipment Needed

You don’t need fancy equipment to make great high fiber apple cinnamon oatmeal. Here’s what I use:

Medium saucepan with lid
Cutting board and knife for the apple
Measuring cups and spoons
Stirring spoon
For overnight oats in a jar: Mason jars or airtight containers
Optional but helpful: Blender if making blended overnight oats

That’s it! This recipe fits perfectly into regular kitchens with regular equipment. No special gadgets required, which makes it accessible for everyone, from college students in dorm kitchens to busy parents trying to get breakfast on the table.

Why You’ll Love This Recipe

This high fiber apple cinnamon oatmeal has earned its permanent spot in my breakfast rotation for several reasons:

It genuinely tastes like comfort food while being genuinely good for you. The warm spices and sweet apples make it feel indulgent, but the nutrient profile tells a different story.

The make-ahead flexibility is unmatched. Whether you prefer stovetop, overnight oats, or even microwaving individual portions, this recipe adapts beautifully.

It keeps you satisfied for hours. The combination of fiber, protein, and healthy fats prevents the mid-morning energy crash that often follows less substantial breakfasts.

Customization is endless. Add different fruits, nuts, or spices based on your preferences or what’s in season.

It’s budget-friendly. Oats are one of the most affordable whole grains, and apples are typically reasonably priced year-round.

Healthier Alternatives for the Recipe

This high fiber apple cinnamon oatmeal is already quite healthy, but here are some simple tweaks to adjust for specific dietary needs or preferences:

For higher protein: Add an extra scoop of protein powder or stir in Greek yogurt after cooking. You could also add a tablespoon of hemp hearts.

Lower sugar: Reduce or omit the maple syrup and rely on the natural sweetness of the apple. A pinch of cinnamon often enhances the perception of sweetness too.

Gluten-free: Use certified gluten-free oats. All other ingredients are naturally gluten-free.

Dairy-free: The recipe as written is dairy-free when using water or plant-based milk.

Lower carbohydrate: While oats are carbohydrates, you could reduce the portion size and bulk it up with extra chia seeds and nuts to create a more balanced macronutrient profile.

For extra creaminess: Stir in a tablespoon of almond butter or cashew butter at the end. This adds healthy fats and makes the texture incredibly luxurious.

Serving Suggestions

This high fiber apple cinnamon oatmeal is wonderful on its own, but a few thoughtful toppings can transform it into something special:

Drizzle with additional maple syrup or a dollop of Greek yogurt
Sprinkle with extra cinnamon or apple pie spice
Top with additional chopped apples or other fruits like berries or sliced bananas
Add crunch with more chopped nuts, pumpkin seeds, or a sprinkle of granola
For a special treat, a spoonful of my Pumpkin Spice Granola Recipes That Will Transform Your Breakfast Today adds wonderful texture and flavor

Pair your oatmeal with a source of protein if you need extra staying power—a hard-boiled egg or a slice of my Vegan Pumpkin Bread makes a complete, satisfying meal. For those who prefer portable breakfasts, this recipe converts beautifully into healthy snacks when portioned into smaller containers.

Common Mistakes to Avoid

After making countless batches of high fiber apple cinnamon oatmeal, I’ve identified a few common pitfalls and how to avoid them:

Using quick oats when the recipe calls for old-fashioned (or vice versa). Quick oats will become mushy if cooked as long as old-fashioned oats. Adjust cooking time accordingly—quick oats need only 3-5 minutes.

Overcooking the apples. If you prefer some texture to your apples, add them after the oats have cooked for a few minutes rather than at the beginning.

Skipping the salt. Even a tiny pinch makes a significant difference in balancing the sweetness and enhancing the other flavors.

Stirring too vigorously or too often. Gentle, occasional stirring is all that’s needed. Over-stirring can break down the oats and make the texture gummy.

Not allowing it to rest after cooking. Those few minutes off the heat allow the oats to fully absorb liquid and thicken to the perfect consistency.

Storing Tips for the Recipe

This high fiber apple cinnamon oatmeal stores beautifully, making it ideal for meal prep:

Refrigerator: Transfer cooled oatmeal to airtight containers and refrigerate for up to 5 days. The texture will thicken as it sits—just stir in a splash of milk or water when reheating.

Freezer: Portion cooled oatmeal into freezer-safe containers or bags and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheating: Add a tablespoon or two of liquid per serving and microwave in 30-second intervals, stirring between each, until heated through. Alternatively, reheat gently on the stovetop over low heat, stirring frequently.

For overnight oats: Prepare your overnight oats in a jar and they’ll keep beautifully in the refrigerator for up to 4 days. The texture actually improves after the first day as the oats fully hydrate.

Conclusion

This high fiber apple cinnamon oatmeal has become more than just a breakfast in my home—it’s a reliable morning ritual that sets a positive tone for the entire day.
