Reasons You’ll Make It Again

Ingredients and Pantry Staples

• 2 ¾ cups old fashioned rolled oats (certified gluten-free, if needed)
• 2 teaspoons pumpkin pie spice
• 1 teaspoon baking powder
• ¼ teaspoon fine salt
• 1 cup pumpkin puree
• 1 cup milk of choice
• 2 large eggs
• ⅓ cup pure maple syrup or honey
• ¼ cup unsalted butter or coconut oil, melted
• 2 teaspoons pure vanilla extract
• ½ cup chopped pecans, toasted + more for topping (omit for nut-free)

Baking Directions and Timing

1. Preheat oven to 375°F (190°C) and grease a 9×9-inch baking dish with butter or nonstick spray.
2. If using a flax egg, mix 2 tablespoons ground flaxseed meal with 3 tablespoons water and let thicken 5–10 minutes.
3. Toast pecans (optional): warm them in a small skillet over medium-low, stirring frequently until lightly darkened and fragrant (about 5–7 minutes), then cool.
4. In a large bowl, whisk together dry ingredients: 2 ¾ cups old-fashioned rolled oats, 2 teaspoons pumpkin pie spice, 1 teaspoon baking powder, and ¼ teaspoon fine salt.
5. Melt ¼ cup unsalted butter or coconut oil if using.
6. In a separate bowl, whisk together wet ingredients: 1 cup pumpkin puree, 1 cup milk, 2 large eggs (or prepared flax egg), ⅓ cup maple syrup or honey, melted butter or coconut oil, and 2 teaspoons vanilla until smooth.
7. Pour wet mixture into dry ingredients and stir until just combined; gently fold in ½ cup toasted chopped pecans if using.
8. Transfer batter to the prepared baking dish and smooth the top with a spatula; sprinkle additional toasted pecans on top if desired.
9. Bake for 30–34 minutes, until the center is set and a toothpick inserted in the center comes out clean or with a few damp crumbs.
   

   

10. Let the baked oatmeal sit for about 5 minutes, then cut into 9 squares.

Kitchen Tips and Shortcuts

I enjoy my pumpkin baked oatmeal served warm right out of the oven for a comforting breakfast. While it’s tasty plain, I love to add toppings that boost flavor and texture.

Some of my favorite add-ons are fresh blueberries, dried cranberries, banana slices or a crunchy handful of cinnamon-sugar air fryer banana chips, chopped pecans, chia seeds, a swirl of peanut or almond butter, brown sugar, or even more pure maple syrup. It also pairs wonderfully with a generous spoonful of Greek yogurt or a cloud of whipped cream.

To balance the meal, I often add a high-protein side or drink.

You can also enjoy this baked oatmeal as an afternoon snack with warm apple cider—pair it with quick air fryer apple chips for extra crunch—or turn it into a quick and comforting breakfast-for-dinner. It really saves the day during busy evenings!

Flavor Swaps and Mix-Ins

I aimed to make this pumpkin baked oatmeal recipe as flexible as possible to suit different dietary needs. The good news? It stays just as delicious without eggs. Here’s how to make it egg-free:

1. Mix 2 tablespoons of ground flaxseed with 3 tablespoons of water in a small bowl.
2. Let the flaxseed and water sit for 5-10 minutes to thicken fully.
3. Then, use this flax egg just like a regular egg when mixing your baked oatmeal batter.

For a dairy-free version, I swap in unsweetened almond milk or any plant-based milk you like. Instead of butter, I use melted coconut oil. And if you’re adding extras like protein powder, chocolate chips, or whipped cream, just double-check that those are dairy-free too, so no surprises!

Storing and Reheating Tips

One thing I love about this pumpkin baked oatmeal is how well it keeps. You can make it ahead and store it in the refrigerator for up to a week. That means you only have to prep once and enjoy warm breakfasts all week long—major time saver! If you like prepping once for the week, you might also enjoy my Maple Donut Bars for another make-ahead breakfast option.

After it cools, I either cover the whole pan with foil or cut the oatmeal into bars and pop them in a glass container. When I’m ready to eat, I microwave a single serving for about 1 minute and 30 seconds—it’s the perfect warm-up time. If you want it softer, just add a splash of milk before heating. Or, if you’re on the go, these bars are great cold too, kind of like a soft oat snack. For a sweeter grab-and-go treat, try Chewy Pumpkin Snickerdoodle Cookies.

FAQs and Quick Answers

• What type of oats should I use? Old-fashioned rolled oats are best. Quick oats get too mushy when baked, and steel-cut oats won’t soften enough.
• Can I make this vegan? Absolutely! Use the flax egg method (2 tbsp ground flax + 3 tbsp water), a plant-based milk, and swap butter for coconut oil or any dairy-free option. Use maple syrup or another vegan sweetener. For another cozy plant-based pumpkin bake, try our Vegan Pumpkin Spice Cake.
• How long will leftovers keep? Keep your baked oatmeal refrigerated in an airtight container for up to 1 week.
• Can I freeze the baked oatmeal? Yes! Portion it out, wrap well or use airtight containers, and freeze for 2–3 months. Thaw overnight in the refrigerator before reheating.
• How should I reheat it? Microwave individual servings for about 1 minute 30 seconds, adding a splash of milk for creaminess. You can also warm it in a 350°F oven until heated through.
• What’s the best way to toast pecans without burning them? Toast pecans slowly in a small pan over medium-low heat, stirring often for about 5–7 minutes. Once they darken a bit and smell fragrant, remove immediately to cool.
• Can I add mix-ins? Definitely! Stir in or top with banana slices, fresh berries, dried cranberries, chocolate chips, chia seeds, or nut butter. Just be mindful of adding too much extra wet ingredients, as that could affect baking time slightly.
