High Protein Healthy Apple Baked Oatmeal

Ingredients

Main Ingredients
  • □ 2 cups 2 cups old-fashioned rolled oats
  • □ 2 2 scoops vanilla whey protein (about 62g)
  • □ 1 tablespoon 1 tablespoon ground cinnamon
  • □ ¼ teaspoon 1/4 teaspoon salt
  • □ 1 teaspoon 1 teaspoon baking powder
  • □ 1 medium 1 medium apple (about 160g, with skin), diced
  • □ 1 cup 1 cup unsweetened applesauce
  • □ 1 cup 1 cup non-fat milk (or any milk of your choice)
  • □ 1 large 1 large egg
  • □ ¼ cup 1/4 cup sugar-free maple syrup
Main Ingredients
  • □ 1 In a large mixing bowl, combine:
  • □ 2 cups 2 cups rolled oats
  • □ 2 2 scoops vanilla whey protein
  • □ 1 tablespoon 1 tablespoon cinnamon
  • □ 1 teaspoon 1 teaspoon baking powder
  • □ ¼ teaspoon 1/4 teaspoon salt
  • □ 1 Whisk these together until evenly blended. This helps distribute the protein powder and spices throughout the oatmeal.
Main Ingredients
  • □ 1 In a separate medium bowl, whisk together:
  • □ 1 cup 1 cup non-fat milk
  • □ 1 cup 1 cup unsweetened applesauce
  • □ 1 large 1 large egg
  • □ ¼ cup 1/4 cup sugar-free maple syrup
  • □ 1 Once smooth, gently fold in the diced apple pieces. I like leaving the skin on for extra fiber and natural sweetness.
Main Ingredients
  • □ 1 Pour the wet mixture into the dry ingredients bowl. Using a spatula, gently fold everything together until all the oats are coated. Don’t overmix—the batter should be slightly thick but pourable.

Instructions

  1. Baking this high-protein apple oatmeal is easier than it sounds—I promise! Follow these steps, and you’ll have a warm, comforting breakfast ready in under an hour.

  2. First, preheat your oven to 350°F (175°C). While the oven warms up, lightly grease your 8x8-inch baking dish with a bit of butter or non-stick spray. This ensures your oatmeal doesn’t stick and makes cleanup a breeze.

  3. Transfer the mixture into your prepared baking dish and smooth the top evenly. Bake in the preheated oven for 35–40 minutes, or until the top is golden and a toothpick inserted into the center comes out clean. The aroma of cinnamon and baked apple will fill your kitchen—it’s heavenly!

  4. Let the baked oatmeal cool for about 5–10 minutes. This helps it firm up slightly, making it easier to slice. I like to serve it warm, straight from the dish, and sometimes sprinkle with a few fresh apple slices or chopped chives for a subtle savory note.

  5. This baked oatmeal keeps well, making it perfect for meal prep:

  6. Refrigeration: Store in an airtight container for up to 5 days. Reheat in the microwave for 30–60 seconds before serving.

  7. Freezing: Slice into portions and wrap individually with parchment or foil, then place in a freezer-safe bag. Freeze for up to 2 months. Thaw overnight in the fridge or microwave for a quick breakfast.
