Ingredients
3tablespoonsunsalted buttermelted, plus more for greasing
1small banana (optional)
2cupsmilk, dairy or non-dairy (I use almond milk)
2large eggs
1/3cupmaple syrup or honey, plus more for serving (optional)
2teaspoonsvanilla extract
2 1/2 cupsold-fashioned oats
1teaspoonbaking powder
2teaspoonsground cinnamon
1/2teaspoonkosher salt
2cupsblueberries, divided
½cupchoppedtoasted nuts or coconut flakes (optional)
Instructions
Heat the oven to 350ºF and grease a 9-by-9-inch baking pan (or similar) with a bit of butter (or coconut oil for vegan version).
In a large mixing bowl, mash the banana (if using). Add the milk, eggs, maple syrup, melted butter and vanilla; whisk until smooth. Stir in the oats, baking powder, cinnamon and salt, and stir until combined.
Pour half of the oat mixture into the prepared pan (just eyeball it!). Sprinkle 1 1/2 cups blueberry evenly on top, then pour remaining oat mixture over the blueberries. Top with remaining 1/2 cup blueberries and sliced almonds, if using.
Bake, uncovered, until just set in the center and top is golden brown, 35 to 40 minutes. Cool for 5 minutes, then serve as is or with additional maple syrup and/or a dollop of yogurt on the side, if desired.
Notes
Use Old-Fashioned Oats. Old-fashioned oats provide the perfect texture for baked oatmeal. Avoid quick oats as they are chopped into finer pieces and can become mushy and ruin the consistency of the dish.
Don’t mix oats with milk too early. Mixing the oats with milk ahead of time can result in overly soft oatmeal with a gummy texture because the oats will absorb too much liquid before baking. Combine them right before baking for the best results.
Fresh vs. frozen blueberries. Either works, but if using frozen blueberries, don’t thaw them beforehand to prevent excess liquid from making the oatmeal soggy.
Sweetness level. Adjust the sweetness to your preference by using more or less maple syrup or honey. You can also sprinkle a bit of brown sugar on top for a caramelized finish.
Double the recipe. This a great dish to feed a hungry breakfast crowd or to serve many breakfasts during the week. If doubling, use a 9x13 baking dish and bake an additional 10 to 12 minutes cooking time.
