Slow Cooker Apple Cinnamon Oatmeal Breakfast: Easy Recipe for Oven or Air Fryer Too

Struggling with boring breakfast routines? I'm no fan of sandwiches every morning and crave variety. That's why I love this warm apple oatmeal made in the slow cooker—a fresh twist far better than plain cheese crackers or yogurt with kiwi. It's hearty, comforting, and perfect for busy mornings.

Recipe: Apple Oatmeal Breakfast for Slow Cooker, Air Fryer, or Oven

If you own a slow cooker, it's the ideal choice for this recipe. Prep it the night before—use the timer if available, or just switch it on. It stays warm on the keep-warm setting, so no worries about overcooking. I've tested this countless times for effortless mornings.

Below, I'll share air fryer and oven options too, but first, the ingredients—enough for 2 servings.

Ingredients for Apple Oatmeal Breakfast

  • 5 apples
  • 6 tablespoons oatmeal
  • 1.5 tablespoons flour or spelt flour
  • 3 teaspoons cinnamon
  • 3 slices of butter

For extra sweetness, add sugar or a sweetener, though it's delicious without—the cinnamon-spiced apples evoke classic apple pie flavors. Pro tip: Sprinkle shredded coconut on top for a festive touch.

How to Make This Oatmeal Breakfast in the Slow Cooker

It's as simple as my peach cobbler recipe (check it out on the site). Peel the apples and layer them in the slow cooker. Mix in the oats, flour, cinnamon, and optional sugar. Top with butter slices. Drape a tea towel over the lid to catch condensation, set to low, and cook for 4 hours. Breakfast bliss awaits!

Oven Method for Apple Oatmeal Breakfast

Follow the same steps: Combine everything in an oven-safe dish and bake at 180°C for about 20 minutes. Warm, gooey, and ready to enjoy.

Air Fryer Apple Oatmeal Breakfast

The air fryer works perfectly—no need to preheat a full oven. Ensure it fits your tray (it fits my XXL model's perfectly; use the baking tray, not the basket). Set to 150°C for 15 minutes. Quick, efficient, and one of my favorite hacks with essential air fryer accessories.
