Ingredient notes
Here's what you need to make this Vegan Strawberry Rhubarb Baked Oatmeal!
Dry Ingredients
- rolled oats -- For this recipe, I prefer the texture of rolled oats, but I also tested the recipe with quick-cooking oats, and it worked out fine!
- ground flax seed -- This acts as an egg substitute and holds everything together.
- cinnamon -- Cinnamon adds a nice flavor to the dish.
- baking powder -- This just helps give the baked oats a little rise.
- salt -- Just to enhance the other flavors.
Wet Ingredients
- soy milk -- Any type of plant milk should be fine. I prefer soy since it's generally the most affordable and higher in protein.
- unsweetened applesauce -- This will add some natural sweetness and help bind the ingredients.
- maple syrup -- This adds most of the sweetness plus a touch of flavor.
- almond butter -- For a bit of protein plus a nutty flavor.
Fruit
- strawberries -- I used fresh, ripe strawberries, but frozen should also be fine.
- rhubarb -- You'll need two to 3 stalks of rhubarb, depending on the size. When selecting, go for rhubarb with firm, crisp stalks and fewer blemishes. The color can vary from red to green but does not impact the flavor. Be sure to remove any leaves before consuming, as they are toxic.
See recipe card for quantities.
Instructions
Here are step-by-step instructions with photos.
- Preheat the oven to 375F or 190C and lightly spray a 8-inch baking dish with cooking spray (or line with parchment paper.)
- Add all of the dry ingredients to a mixing bowl and whisk to combine.
- Add all of the wet ingredients to the bowl and mix to combine.
- Wash the strawberries and rhubarb, remove the stems, leaves, and ends, and chop into medium-sized cubes. (I like to do this step here because it gives the oats a few minutes to absorb the wet ingredients.)
- Add the cubed strawberries and rhubarb and fold into the batter.
- Transfer the batter to the baking dish. Top with a few strawberry slices (optional).
- Bake for about 30 minutes or until the center is done, then remove from the oven and let cool for 5 minutes. Serve with vegan yogurt, walnuts, another drizzle of maple syrup, or any of your favorite toppings.
Hint: The exact baking time can vary based on the size and material of the dish, so keep a close on it the first time you make this recipe.
Variations
Here are a few ways to switch things up!
- Nutty - add a handful of your favorite nuts to the batter.
- Berry Berry - If you don't have fresh strawberries, blueberries or raspberries will also work.
- Banana - I don't love bananas in baked goods, but if you do, just swap out the apple sauce for ripe mashed bananas.

Top Tip
Rhubarb might seem like a scary ingredient if you've never cooked with it before. But it's very easy to prep. Just wash it, chop off the ends, and dice it up like celery! No other work needed. Always be sure to remove the leaves though, as they are toxic.
FAQ
Rhubarb is a plant with red or green edible stalks. It looks very similar to celery but has a tart, sour, or tangy flavor that goes well with sweet dishes and pairs especially well with strawberries.
If you want to make this recipe when Rhubarb is out of season, you can double the strawberries or swap out other berries for the rhubarb. Try adding a teaspoon or two of lemon juice to substitute the tartness of the rhubarb.
