This cozy oatmeal bake is warm, spiced just right, and full of sweet potato goodness.

It’s the kind of breakfast that makes your whole kitchen smell amazing.

It’s simple to make, uses real ingredients, and it’s naturally sweetened with maple syrup.

I love whipping this up on a slow weekend morning or baking it ahead to enjoy all week.

What You’ll Need

  • 1 cup rolled oats
  • 1 cup mashed roasted sweet potato (skin removed)

  • Tastes like a warm slice of sweet potato pie, but it’s healthy enough for breakfast
  • Only one bowl and one baking dish to clean
  • It makes your kitchen smell like cinnamon heaven
  • Great warm or cold, and it reheats beautifully

Why This Recipe Works (Quick Science)

  • Sweet potatoes add natural sweetness and moisture, keeping the oats tender.
  • Oats absorb the almond milk while baking, creating a soft, cake-like texture.
  • Baking powder gives it a little lift so it doesn’t turn dense.
  • Cinnamon and nutmeg bring out the sweetness of the sweet potatoes and maple.

Common Mistakes

  • Using raw sweet potato: Roast it first or it won’t mix in right and will taste undercooked.
  • Skipping the salt: A pinch of salt balances all the sweet flavors.
  • Overbaking: It should be soft and just set. Don’t bake until totally firm or it’ll dry out.
  • Not greasing the dish: Coconut oil helps prevent sticking and adds a hint of flavor.

What to Serve With

  • Dollop of Greek yogurt or coconut cream
  • Extra drizzle of maple syrup
  • Fresh fruit like sliced bananas or apples
  • Hot cup of coffee or chai

FAQ

Can I use canned sweet potato puree?
Yes, just make sure it’s plain and not the pie filling with added sugar.

Can I make this vegan?
It already is! Just use plant-based milk and coconut oil as written.

Can I double the recipe?
Yes, use a 9×13 baking dish and bake a little longer—check at 30 minutes.

Can I make it nut-free?
Sure! Just skip the pecans or sub with seeds like pumpkin or sunflower.

Pro Tips

  • Roast your sweet potato the day before so it’s ready to go.
  • Chop pecans a bit smaller so you get a little crunch in every bite.
  • Grease the baking dish well to avoid sticking.
  • Mix the oats last to keep them from getting too mushy.
  • Let it cool 10 minutes before cutting so it holds its shape.

  • Mixing bowl
  • Whisk
  • 8×8-inch baking dish
  • Measuring cups and spoons
  • Spatula

Substitutions and Variations

  • Use pumpkin puree instead of sweet potato
  • Try walnuts or almonds instead of pecans
  • Use regular milk if you’re not dairy-free

Make Ahead Tips

Instructions

Step 1: Roast and mash the sweet potato

Roast a medium sweet potato at 400°F for about 45 minutes until fork-tender. Once cooled, peel and mash until smooth. Measure 1 cup.

Step 2: Mix the wet ingredients

In a large mixing bowl, whisk together 1 cup mashed sweet potato, 1 ¼ cups almond milk, ¼ cup maple syrup, 1 teaspoon vanilla extract.

Step 3: Add dry ingredients

Add 1 cup rolled oats, 1 teaspoon cinnamon, ¼ teaspoon nutmeg, ½ teaspoon baking powder, and a pinch of salt. Stir until fully combined.

Step 4: Fold in the pecans

Fold in ⅓ cup chopped pecans gently with a spatula so they’re evenly spread throughout the mixture.

Step 5: Pour into baking dish

Grease an 8×8-inch baking dish with 1 tablespoon melted coconut oil. Pour the mixture in and smooth the top. Add a few extra pecans on top.

Step 6: Bake

Bake at 350°F for 25 minutes until the center is just set and the edges look golden. Let cool at least 10 minutes before slicing.

Step 7: Serve

Cut into 4 slices and serve warm with maple syrup or yogurt.
