Blueberry Protein Baked Oatmeal for Breakfast Meal Prep

I’m Silmara Souza from Foco News, and this blueberry protein baked oatmeal turns a bowl of oats into easy squares for make-ahead breakfasts. Greek yogurt and eggs help bind the mixture, while blueberries keep the center moist without making it feel like cake.

Before you start

Preheat the oven to 350°F (175°C) and grease an 8-inch square baking dish. Frozen blueberries can be used directly from the freezer; do not thaw them first.

Ingredients

• 2 cups (180 g) rolled oats
• 1 teaspoon baking powder
• 1 teaspoon cinnamon
• 1/4 teaspoon salt
• 2 large eggs
• 1 1/2 cups (360 ml) milk
• 3/4 cup (180 g) Greek yogurt
• 1/4 cup maple syrup
• 1 teaspoon vanilla extract
• 1 1/2 cups blueberries, fresh or frozen

Ingredient substitutions

• Use certified gluten-free oats when needed.
• Use dairy-free yogurt and plant milk.
• Replace blueberries with raspberries or diced apple.
• For additional protein, add a small amount of protein powder and extra milk according to its absorption.

Equipment, time and yield

Prep time: 15m. Cook time: 35m. Yield: 9 squares. Difficulty: beginner-friendly. Use standard measuring cups and spoons, a clean cutting board and the cookware named in the instructions.

Step-by-step instructions

1. Mix oats, baking powder, cinnamon and salt in a large bowl.
2. In a second bowl, whisk eggs, milk, yogurt, maple syrup and vanilla until smooth.
3. Pour wet ingredients into the oats and stir until evenly combined.
4. Fold in one cup of blueberries, reserving the rest for the top.
5. Spread in the prepared dish and scatter remaining berries evenly.
6. Bake for 32 to 38 minutes, until the center is set and the edges are lightly browned.
7. Cool for at least 15 minutes before cutting into nine squares.

Beginner tips

Let the oats absorb the liquid for five minutes before baking if you prefer a softer center. Do not overbake; the squares continue to firm while cooling.

Serving ideas

Build a balanced plate around the recipe rather than treating one food as a complete diet plan. Add vegetables, fruit, whole grains or a simple yogurt sauce according to the meal and your needs.

Storage and food safety

Refrigerate in a sealed container for up to five days. Reheat individual squares with a spoonful of milk. Freeze for up to two months with parchment between portions.

Final notes

Measure the ingredients on your first attempt, pay attention to texture and temperature, and write down any timing adjustment required by your equipment. That small note makes the next batch much easier.
