Ingredients needed

Blueberry baked oatmeal is made with good-for-you, nutritious ingredients and tasty add-ins, like vanilla, maple syrup, and blueberries. Here’s what you need to make it:

  • Eggs: This recipe uses two eggs to provide structure and bind all of the ingredients together.
  • Vanilla extract: For warmth and flavor.
  • Rolled oats: The base of this baked oatmeal uses old-fashioned rolled oats. Use certified gluten-free oats, as needed. However, do NOT use quick oats or steel-cut oats because the texture will not turn out right.
  • Milk: Any milk variety will work. For a dairy-free option, use almond milk or cashew milk.
  • Maple syrup: To naturally sweeten the dish. Honey or agave would work great as a substitute.
  • Fresh blueberries: Use fresh berries as a topping, but you may use frozen berries to fold into the oatmeal before baking, no need to thaw.
  • Zucchini: Shredded zucchini adds the perfect amount of moisture and extra nutrients. And you won’t be able to taste it at all!

Frequently asked questions

Is baked oatmeal healthy?

Oats are very healthy. They’re a gluten-free whole grain and a great source of vitamins, minerals, fiber, and antioxidants. Research shows that oats and oatmeal have many health benefits, including weight loss, lower blood sugar levels, lowering cholesterol, and a reduced risk of heart disease.

Is baked oatmeal good the next day?

Yes! Baked oatmeal stores very nicely once baked. We don’t recommend storing the batter, though. Once stirred together, it needs to be baked promptly; otherwise, the oats continue to absorb liquid and the baked oatmeal will be dry. Store leftovers, covered, in airtight containers for 4 to 5 days. Reheat individual portions in the microwave. If the oatmeal has dried out too much for your preference, serve leftovers in a bowl with a splash of milk.

What does baked oatmeal taste like?

Baked oatmeal is a sweet breakfast that’s soft and custardy with a chewy texture and crisp edges. It’s a unique taste and texture, you can’t get with a stovetop or microwave oatmeal.

Storing, freezing, and reheating

  • Storing leftovers: Place any leftover baked oatmeal in an airtight container or plastic, in the fridge for up to 4 days.
  • Freeze: Place individual servings in an airtight, freezer-safe container or freezer-safe bag for up to 3 months.
  • Reheat: Place individual slices in the microwave for about 1 to 4 minutes, depending on whether it’s at room temperature or frozen.
