WHAT’S NEW?

Can I let you in on a little secret? I have baby fever like WHOA. I don’t know if it’s Shea’s first birthday that is less than 30 days away (I will need tissue and lots of it to get through that day, people!)…

…or my recent 30th birthday…

…or the fact that I love being a mom more than anything in this world (even donuts!), but yeah…I’m ready for another baby. I was ready, like, yesterday.

I know my chances of conceiving again are greatest if I’m mentally, emotionally, and most importantly, physically prepared. A wholesome, plant-based healthy breakfast is a great way to include whole grains and fresh berries!

ROLL CALL FOR THIS RECIPE

  • Flavor: The delicious flavor combination of lemon and sweet blueberries is unrivaled. It’s simply the best!
  • Kid-Friendly: While this recipe is kid-friendly as-is, it’s fun to add a dollop of lemon curd or more juicy blueberries when serving.
  • Make-Ahead: This oatmeal bake is perfect for breakfast meal prep – it is served great as leftovers cold, at room temperature, or rewarmed. Delicious!

KEY INGREDIENTS AND SUBSTITUTIONS

  • Eggs: You can substitute in 1/2 cup egg substitute of egg whites or for a vegan option, a double flax egg (see below).
  • Honey: Pure maple syrup or agave can be subbed in. If you use brown sugar, use an additional 1/4 to 1/3 cup of milk.
  • Lemon: Meyer lemons are floral and sweet, lacking much of the tart or sour flavor of traditional citrus. That said, you can swap regular lemon juice and zest but may want to increase the honey by 10-20%.
  • Vanilla: Pure vanilla extract makes the blueberry lemon flavors truly “pop”, however it can be left out or another extract, such as almond extract, can be used in its place.
  • Baking Powder: You can use 1/2 teaspoon baking soda and 1 teaspoon white vinegar as a substitute for the baking powder, if needed. 
  • Salt: A bit of salt helps with both leavening and flavor.
  • Milk: I used unsweetened almond milk, however use whatever milk variety you prefer – cow’s milk, cashew milk, oat milk, coconut milk, soy milk, hemp milk, or whatever other non-dairy milk you prefer! Additionally, you can use some Greek yogurt and some milk as a part of the wet ingredients. 
  • Oats: Any oat variety other than steel cut oats can be subbed in for old fashioned oats — rolled oats, quick oats, etc.
  • Blueberries: Add additional blueberries or less if you prefer. Fresh blueberries or frozen work great! Other fruits can be used, too (see FAQ for suggestions).

VARIATIONS, STORAGE, and TIPS

  • Store leftovers in an airtight container for up to 4-5 days in the fridge.
  • Get creative with baked oatmeal recipes and try different fresh fruit combinations and new flavors, including zesty lemons and other additions such as nuts, chia seeds, flax seeds, and more!
  • If you prefer to mix dry ingredients in a separate bowl from wet ingredients, feel free. I prefer to mix the whole thing together in a single large mixing bowl to save on dishes.
  • Consider adding your favorite protein powder for additional protein in these baked oats

FAQ 

How do you make a flax egg (double)?

Mix 2 tablespoons of ground flaxseed with 6 tablespoons of warm water and set aside until slightly congealed. Add to the recipe as you would the eggs and follow directions as listed. 

What fruits other than blueberries can be used in a baked oatmeal recipe?

There’s endless options of fruits and flavor combinations to try in baked oatmeal. Apples and cinnamon is a favorite, as is apple and peanut butter or pear and cardamom. Peaches and strawberries also work great in baked oatmeal.

Can this recipe be made as individual servings versus in a baking pan or casserole dish?

Yes, making baked oatmeal as oatmeal cups is convenient and lots of fun to serve as a single serving. Prepare a muffin tin by spraying the wells with non-stick cooking spray (oil) and filling each muffin well about two-thirds full. Bake in a preheated oven at 350 degrees for 25 minutes or until golden brown on top and set.

    I plan to make this for a morning meeting this week. I plan to double it and put together the next get before I bake it. My grocery does not carry Meyer lemons. I’m not familiar with them. Are they as tart and comparable in size? In other words, can I just sub in regular lemons? Thank you-looks wonderful!!

      Hi Lora! Meyer lemons are sweeter and jucier – but regular lemons will sub in just fine. 🙂 Enjoy!
