Oven-Baked Pumpkin Steel-Cut Oatmeal Recipe

Oatmeal has long been a favorite breakfast for many because it’s comforting, versatile and easy to customize. Steel cut oats offer a heartier, chewier texture than rolled oats and lend a pleasantly nutty flavor to baked oatmeal dishes. By soaking the steel cut oats overnight, they soften enough to bake into a tender, slightly chewy bake that still holds together when cut into squares.

This Pumpkin Baked Steel Cut Oatmeal features pumpkin puree and pumpkin pie spice for a classic fall flavor profile. Chia seeds act as a binder in place of eggs, while almond milk keeps the recipe dairy-free and vegan-friendly. The finished bake is delicious on its own with a drizzle of maple syrup or dressed up with yogurt, fresh fruit or a sprinkle of additional nuts and chocolate chips.

Recipe ingredients

• Steel cut oats — soak overnight to achieve a softer texture while retaining a pleasant chew.

How to make steel cut oat baked oatmeal

This recipe follows a simple two-step approach: soak the oats overnight, then bake the mixture the next day. Soaking is optional but recommended for a softer texture and quicker bake. Do not use quick-cooking steel cut oats for this preparation.

1. In a medium bowl, combine the steel cut oats, chia seeds, maple syrup, pumpkin puree, pumpkin pie spice and almond milk. Stir until combined.
2. Cover and chill the mixture in the refrigerator overnight to soften the oats.
3. The next morning, preheat the oven to 350°F (175°C) and grease an 8×8″ baking dish. Optional: allow the chilled oats to sit at room temperature for 30 minutes to reduce baking time.
4. Stir the oats, pour into the prepared dish and bake for 30 minutes.
5. Remove the dish, sprinkle pecan halves over the top, then bake another 20–25 minutes until the oatmeal is set and no longer jiggly in the center. If the top starts to brown too quickly, cover loosely with foil.
6. Allow to cool slightly on a wire rack before cutting into squares. Serve warm with a drizzle of maple syrup or your preferred toppings.

Soaking steel cut oats in liquid overnight softens them and often reduces baking time. If you prefer not to soak, plan for slightly longer bake time and expect a firmer, chewier texture.
