Becky’s Tips

*Instead of blueberries, diced apples, pears, or strawberries are wonderful additions. Delicate berries like raspberries and blackberries could fall apart, so I recommend using 1 cup of blueberries and 1 cup of raspberries or blackberries.

Get the oven going and prepare a baking pan: Preheat the oven to 375°F and spray an 8×8-inch baking pan with nonstick spray. Set aside.

Gather your ingredients.

Combine the dry ingredients: Whisk 2¼ cups old-fashioned oats, ½ cup brown sugar, 1 tsp baking powder, and ¼ tsp allspice in a large bowl.

Combine the wet ingredients: In a separate bowl, mix 2 cups half and half, 2 large eggs, 2 tbsp salted butter, 1 tbsp lemon juice, 1 tbsp honey, and ½ tsp pure vanilla extract.

Combine wet and dry ingredients: Pour the wet mixture over the oat mixture and mix well.

Add the blueberries: Gently fold in 2 cups blueberries and 1 cup pecans. For an even texture, make sure the ingredients are well mixed before spreading them into the baking dish.

Transfer the batter and bake: Pour the batter into the baking pan and spread it into an even layer. Bake for 40-45 minutes or until golden brown.

Cool and serve: Let cool before plating and serving. Enjoy!

How to Store

This is a wonderful recipe to make ahead of time. Let the oatmeal cool to room temperature and store it in an airtight container in the refrigerator for up to 5 days.

Wrap cooled baked oatmeal squares individually in plastic wrap and place into an airtight container in the freezer for up to 3 months. Thaw squares overnight in the refrigerator.

Serving Suggestions

I love topping my baked oatmeal with maple syrup or honey and adding more fruit on top, whether it’s fresh berries or blueberry compote. For a complete breakfast, I’ll serve it with a side of air fryer bacon and a warm and comforting banana bread latte.
