Juicy peaches, plump blueberries, warm cinnamon, vanilla, and toasted pecans turn ordinary oatmeal into a comforting breakfast that tastes a little like peach cobbler.

This baked oatmeal is lightly sweet rather than dessert-sweet, allowing the fruit to remain the star. It can be prepared ahead, sliced into individual servings, and reheated throughout the week.

Ingredients

• 1 tablespoon ground flaxseed

• 3 tablespoons warm water

• 2 cups old-fashioned rolled oats

• 1 teaspoon baking powder

• 1 1/2 teaspoons ground cinnamon

• 1/4 teaspoon ground nutmeg

• 1/2 teaspoon salt

• 1 3/4 cups unsweetened plant milk, such as soy, oat, or almond milk

• 1/3 cup pure maple syrup

• 1/3 cup unsweetened applesauce

• 2 teaspoons pure vanilla extract

• 1 teaspoon finely grated lemon zest, optional but recommended

• 2 cups peeled or unpeeled diced peaches

• 1 cup fresh or frozen blueberries

• 1/2 cup chopped pecans, divided

• Plant-based yogurt or additional fruit for serving, optional

Directions

1. Preheat the oven to 350°F. Lightly grease an 8-inch square baking dish or line it with parchment paper.

2. In a small bowl, combine the ground flaxseed and warm water. Stir and set aside for 5 to 10 minutes, until the mixture begins to thicken.

3. Place the rolled oats, baking powder, cinnamon, nutmeg, and salt in a large mixing bowl. Stir until the spices are evenly distributed.

4. In a separate bowl or large measuring cup, whisk together the plant milk, maple syrup, applesauce, vanilla, lemon zest, and thickened flaxseed mixture.

5. Pour the wet ingredients over the oat mixture. Stir well and allow it to rest for 5 minutes so the oats can begin absorbing the liquid.

6. Gently fold in 1 1/2 cups of the peaches, 3/4 cup of the blueberries, and 1/4 cup of the chopped pecans.

7. Pour the mixture into the prepared baking dish and spread it evenly.

8. Arrange the remaining peaches and blueberries across the top. Sprinkle with the remaining pecans and a light dusting of cinnamon.

9. Bake for 38 to 45 minutes, until the center is set and the edges are lightly golden. The center should feel firm when gently pressed, although it will remain softer than a traditional cake.

10. Allow the baked oatmeal to rest for at least 10 minutes before cutting. This cooling time helps the servings hold together.

11. Serve warm as it is, or add a spoonful of plain plant-based yogurt, a splash of plant milk, or additional fresh fruit.

Why This Baked Oatmeal Tastes So Good

Peaches and blueberries provide two different kinds of natural sweetness. The peaches become soft and almost jammy as they bake, while the blueberries create brighter bursts of flavor.

Cinnamon, nutmeg, and vanilla give the oatmeal the comforting flavor of a fruit cobbler. Lemon zest does not make the oatmeal taste strongly of lemon. It simply brightens the fruit and keeps the sweetness from tasting flat.

Toasted pecans add a buttery flavor and a welcome contrast to the tender oats and fruit.

Why It Supports Anti-Inflammatory Eating

Blueberries, peaches, pecans, oats, flaxseed, and cinnamon contain naturally occurring plant compounds, including various polyphenols and antioxidants.

An anti-inflammatory eating pattern is not based on one miracle ingredient. It emphasizes a regular variety of fruits, vegetables, whole grains, nuts, seeds, legumes, herbs, and spices. This breakfast brings several of those food groups together in one familiar meal.

Why Your Gut Will Love It

Oats contain beta-glucan, a form of soluble fiber that can be used by gut microbes.

Peaches and blueberries add fruit fibers, including pectin, while flaxseed and pecans provide additional forms of plant fiber. Eating several kinds of fiber-rich plants gives the gut microbiome a wider variety of nourishment.

Other Benefits

Oats provide whole-grain carbohydrates that digest more slowly than many refined breakfast foods.

Pecans and flaxseed contribute unsaturated fats, while the fruit provides vitamin C and colorful plant compounds. Combining whole grains, fruit, seeds, and nuts also makes this breakfast more satisfying than a serving of fruit or sweetened cereal alone.

Choosing Your Peaches

Fresh Peaches

Fresh ripe peaches provide the best summer flavor. The peels can be left on for additional fiber and color, or removed when a softer texture is preferred.

Frozen Peaches

Thaw and drain frozen peaches before dicing. Pat them lightly with a clean towel if they release a great deal of moisture.

Canned Peaches

Choose peaches packed in juice rather than heavy syrup. Drain them thoroughly and pat dry before adding them to the oatmeal.

Using Frozen Blueberries

Frozen blueberries can be added without thawing. Fold them in gently and avoid overmixing, since their juice may turn the oatmeal purple.

The baking time may be a few minutes longer when both the peaches and blueberries are frozen.

Easy Substitutions

Instead of peaches: Use nectarines, apples, pears, or an additional cup of blueberries.

Instead of blueberries: Use blackberries, raspberries, or chopped strawberries.

Instead of pecans: Use walnuts, pumpkin seeds, or sunflower seeds.

For a nut-free version: Choose a nut-free plant milk and replace the pecans with pumpkin or sunflower seeds.

Without applesauce: Use one-third cup of thoroughly mashed ripe banana. The finished oatmeal will have a light banana flavor.

Instead of maple syrup: Use agave nectar.

Without flaxseed: Use 2 tablespoons of chia seeds mixed with 5 tablespoons of water. Let the mixture stand for 10 minutes before using.

For certified gluten-free oatmeal: Choose oats clearly labeled certified gluten-free.

Adjusting the Sweetness

The sweetness of fresh peaches can vary considerably.

Taste a small piece of peach before assembling the recipe. When the fruit is very ripe and sweet, one-third cup of maple syrup should be plenty. When the peaches are tart or canned without added sweetness, another tablespoon of maple syrup can be added.

Additional maple syrup can also be served at the table rather than baked into the entire dish.

Seasonal Garden Note

Peaches and blueberries are natural summer partners in the Southeast. Both may be available from local growers during the warmer months, making this an especially good recipe for farmers-market fruit.

Outside of peach season, frozen peaches and blueberries allow the recipe to be prepared throughout the year.

Make-Ahead Instructions

The dry ingredients can be mixed the night before and kept covered at room temperature.

The wet ingredients can be combined separately and refrigerated. In the morning, stir the two mixtures together, fold in the fruit, and bake.

The entire oatmeal can also be baked ahead and reheated in individual servings.

Storage and Reheating

Allow the oatmeal to cool completely before storing.

Cover the baking dish or place individual servings in an airtight container. Refrigerate for up to five days.

Reheat individual servings in the microwave for 30 to 60 seconds, or place them in a covered baking dish in a 325°F oven until warm.

The baked oatmeal can also be frozen for up to three months. Wrap individual portions or separate them with parchment paper before freezing.

A Gentle Fiber Note

This breakfast contains fiber from oats, fruit, flaxseed, and pecans.

Anyone who currently eats very little fiber may prefer to begin with a smaller serving and increase gradually. Adequate fluids are also important when increasing fiber intake.
