What Goes Into This Recipe – Ingredients

• 2 cups rolled oats (old-fashioned, not instant)
• 1 tsp baking powder
• 1/2 tsp salt
• Zest of 1 lemon (yes, all the zing!)
• 1 tbsp lemon juice (fresh is best, FYI)
• 1/2 tsp cinnamon (optional, but why not?)
• 2 large eggs
• 1 1/2 cups milk (dairy or your fave plant-based alternative)
• 1/3 cup maple syrup (for that natural sweetness)
• 2 tsp vanilla extract
• 1 1/2 cups fresh or frozen blueberries (do NOT skip them)
• 2 tbsp coconut oil or butter (melted)

Let’s Get Cooking – Instructions

1. Preheat your oven to 350°F (175°C) and grease an 8×8 inch baking dish with a little coconut oil or butter.
2. In a large bowl, combine the rolled oats, baking powder, salt, lemon zest, and cinnamon.

   Mix it up to spread that zest and spice love evenly.

3. In a separate bowl, whisk the eggs, milk, maple syrup, lemon juice, vanilla extract, and melted coconut oil until everything’s smooth and inviting.
4. Pour the wet ingredients into the dry and stir until well combined. Don’t worry if it looks a bit thick – that’s perfect.
5. Fold in the blueberries gently, saving a handful for sprinkling on top like the superstar berries they are.
6. Pour the mixture into your prepared baking dish, smooth the top with a spatula, and scatter those remaining berries right on top.
7. Bake for 35-40 minutes or until the top is golden and the oatmeal has set (side note: it should jiggle a little, but not be runny).
8. Let it cool for about 10 minutes, then slice and serve warm with a drizzle of almond butter, extra maple syrup, or a splash of milk.

Why This is Good for You

Avoid These Mistakes

• Don’t skip the lemon zest: The juice alone won’t deliver the flavor punch that zest brings.

  It’s where all the magic happens.

• Overbaking alert: Leaving it in too long turns this beauty into a dry flop. Check around 35 minutes – golden, not burnt.
• Substituting instant oats: Instant oats turn to mush. Old-fashioned is the way to go for that chewy, hearty texture.
• Forgetting to grease the dish: This recipe is sticky!

  Greasing prevents your oatmeal from sticking like an ex in a bad memory.

Recipe Variations

• Nutty Upgrade: Add 1/4 cup chopped almonds or walnuts for crunch.
• Chia Boost: Stir in 1 tbsp chia seeds to pump up the omega-3s and fiber.
• Dairy-Free Dream: Use almond or oat milk and coconut oil for a vegan-friendly version.
• Berry Blend: Mix blueberries with raspberries or blackberries for an even funkier fruit fiesta.
• Spice It Up: Add a pinch of nutmeg or cardamom for an unexpected warm twist.

FAQ

Can I use frozen blueberries in this recipe?

Absolutely! Frozen blueberries work perfectly and won’t drastically alter the texture. Just toss them in straight from the freezer; no need to thaw.

Is this recipe gluten-free?

It’s only gluten-free if you use certified gluten-free rolled oats.

Not all oats are processed gluten-free, so double-check your packaging.

Can I make this recipe vegan?

Yes, by swapping the eggs for flax eggs (1 tbsp flaxseed meal + 3 tbsp water per egg) and using plant-based milk and oil, you can make it vegan-friendly.

How long can I store baked oatmeal?

Store it in the fridge for up to 4 days. For longer storage, freeze individual slices for up to 2 months.

What’s the best way to reheat baked oatmeal?

Microwaving for 30-60 seconds is easiest, but reheating in the oven at 325°F for 10 minutes gives a nice, crispier top.
