Step-by-Step Cooking Instructions

Pre-Cooking Prep

1. Preheat oven to 375°F.

2. Grease an 8×8-inch baking dish.

Doneness or Texture Check

Blueberry baked oats are ready when:

• The center is set, not liquid

• The top is lightly golden

• A knife inserted in the center comes out mostly clean

Resting or Final Touches

Let baked oats cool for 10 minutes before slicing. This helps them set and improves texture. Serve warm or at room temperature.
