Recipe Ingredients

You’ll need the following ingredients to make this Mixed Berry Oatmeal Bake:

Milk: You can use any type of milk in this recipe based on your dietary preference or what you have on hand, including non-dairy alternatives like almond milk, oat, or soy milk. I personally love using Fairlife Ultra Filtered Milk for a protein boost.

Oats: Use old-fashioned rolled oats for the best texture. They absorb the liquid well and hold their shape during baking. Avoid using instant or quick oats as they can become mushy and steel cut oats will have a longer cook time.

Berries: You can use any type of berries you like or have on hand – strawberries, raspberries, blueberries, or blackberries would all work well. If you’re using frozen berries (a triple berry frozen mixture would be a great option), you don’t need to defrost them beforehand. However, they may add a bit more moisture to the bake, so be prepared to add a few extra minutes to the baking time if necessary.

Eggs: The eggs act as a binder in this recipe, keeping everything together. If you follow a vegan diet, you could substitute with flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons of water per egg).

Pure Maple Syrup: This natural sweetener gives a subtle sweetness to the oatmeal bake. If you don’t have maple syrup, honey or agave syrup can be used as alternatives.

Vanilla Extract: Vanilla extract adds depth of flavor and enhances the sweetness of the bake. Make sure to use pure vanilla extract rather than imitation for the best flavor.

Cinnamon: This warm spice pairs well with the berries and adds complexity to the dish. Feel free to adjust the amount to suit your taste.

Baking Powder: This leavening agent helps the oatmeal bake rise and become slightly fluffy. Ensure it’s fresh for the best results.

Rachel’s Nutrition Tip: Mix in one or two scoops of your preferred protein powder for an additional protein punch.

How to make a Berry Oatmeal Bake : Step by Step

Step 1: In a medium bowl beat the milk and eggs until incorporated. Pour the maple syrup, vanilla extract and cinnamon and whisk to incorporate.

Step 2: Add the dry ingredients (oats and baking powder) to the wet ingredients and continue mixing until everything is well incorporated.

Step 3: Gently fold in the berries and let the batter rest for around 30 minutes.

Step 4: Transfer the batter to a casserole dish and bake for 45 minutes or until golden brown. 

Storage, Freezing, & Reheating

Storage: Once the berry oatmeal bake has cooled, you can store it in the fridge. Cut it into individual portions and place them in an airtight container. It will stay fresh for about 4-5 days.

Freezing: This oatmeal bake is excellent for freezing. After it has completely cooled, slice it into individual servings and wrap each piece in plastic wrap or aluminum foil. Then, place the wrapped pieces in a freezer-safe bag or container. Make sure to squeeze out as much air as possible before sealing. Properly stored, it should keep well for up to 3 months.

Reheating: When you’re ready to enjoy the oatmeal bake, you can reheat it in the microwave or oven. For a microwave, place a slice on a microwave-safe plate and heat for 1-2 minutes, or until warmed through. If using an oven, preheat it to 350°F (175°C), place the oatmeal bake on a baking sheet, and warm for about 10-15 minutes, or until heated through.

If you’re reheating from frozen, it’s best to let the oatmeal bake thaw overnight in the fridge before reheating. However, if you’re in a pinch, you can reheat it from frozen – just be aware that it will take a bit longer.

How To Serve

This healthy baked oatmeal recipe can be served in a variety of delicious ways, making it a versatile addition to your breakfast rotation. Here are some ideas:

• Fresh Out of the Oven: There’s something comforting about a warm breakfast, especially when it’s full of wholesome ingredients. Serve a slice of the oatmeal bake fresh from the oven, perhaps with a drizzle of extra maple syrup or a dollop of Greek yogurt.
• Room Temperature: If you prefer, you can let the oatmeal bake cool completely and serve it at room temperature. This is a great option if you’re serving this at a brunch gathering or if you’re bringing it to a potluck.
• With Extra Berries: Top a slice of the oatmeal bake with a handful of fresh berries for added freshness and a pop of color.
• Add a Creamy Element: A spoonful of Greek yogurt, a splash of milk, or a dollop of whipped cream can add a nice contrast to the hearty oatmeal bake.
• Sprinkle of Crunch: Try sprinkling some granola or toasted nuts on top for extra texture and flavor.
• Dessert Option: While this is a breakfast dish, it can also serve as a healthier dessert option. Serve warm with a scoop of vanilla ice cream or a splash of cream for a treat.
• On-the-Go: If you’re in a rush, you can eat a slice just as it is, like a piece of cake or a bar. It’s a portable, mess-free option that’s perfect for busy mornings.
