How to Make Blueberry Baked Oatmeal Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 375°F. Grease an 8×8-inch baking pan with nonstick spray so your Blueberry Baked Oatmeal Recipe comes out perfectly without sticking. This simple prep ensures an even bake and easy cleanup.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together the oats, brown sugar, baking powder, and allspice. Combining these dry ingredients first helps distribute the flavors evenly throughout your oatmeal, setting the stage for a perfectly balanced bite.
Step 3: Combine the Wet Ingredients
In a separate bowl, whisk together the half-and-half, eggs, melted butter, lemon juice, honey, and vanilla extract until everything is smoothly blended. Warm, room-temperature ingredients help with better mixing and a more uniform texture.
Step 4: Bring It All Together
Pour your wet ingredients into the dry oat mixture and stir until fully combined. This is when the oats start soaking in all the creamy goodness that will turn into that luscious baked texture.
Step 5: Add Blueberries and Pecans
Gently fold in the blueberries and chopped pecans. Be careful not to overmix — you want those berries to remain intact, creating gorgeous pockets of juicy flavor throughout the oatmeal.
Step 6: Transfer and Bake
Spread the batter evenly into your prepared pan, smoothing the top with a spatula. Bake for 40 to 45 minutes, or until the top is golden brown and set. You’ll know it’s ready when the edges pull away slightly from the pan and your kitchen is filled with that irresistible baked oat aroma.

FAQs
Can I use frozen blueberries in this recipe?
Absolutely! Frozen blueberries work great if fresh aren’t available. Just fold them in frozen to avoid bleeding too much color into the batter, and your Blueberry Baked Oatmeal Recipe will still be vibrant and delicious.
Is it possible to make this recipe dairy-free?
Yes! Substitute the half-and-half with a plant-based milk like almond or oat milk, and swap the butter for coconut oil or a dairy-free margarine. The texture might be slightly different but still wonderfully tasty.
Can I prepare this Blueberry Baked Oatmeal Recipe the night before?
You can mix all the ingredients the night before and refrigerate the batter. In the morning, simply bake it fresh for about 45 minutes. This makes busy mornings much easier while still enjoying a warm breakfast.
How do I make this recipe sweeter without adding more sugar?
Try adding ripe mashed bananas or a handful of chopped dried fruit like dates or raisins to the oat mixture. These natural sweeteners boost flavor and moisture while keeping things wholesome.
Can I substitute pecans with other nuts?
Definitely! Walnuts, almonds, or even chopped hazelnuts are fantastic alternatives to pecans. Each nut brings a unique texture and flavor, so feel free to experiment with your favorites in the Blueberry Baked Oatmeal Recipe.
