This simple baked oat dessert is the kind of cozy, economical sweet that fits right into a Thanksgiving table when you want something warm, spiced, and easy to assemble with pantry staples. Rolled oats bake into a soft, spoonable pudding-like center with a lightly golden top, and with just six ingredients, it delivers old-fashioned comfort without the work of a pie crust or a long ingredient list.
Serve this dessert warm with a scoop of vanilla ice cream, softly whipped cream, or a spoonful of plain Greek yogurt if you like a less sweet finish. It also pairs nicely with hot coffee, black tea, or spiced cider, and for a full holiday spread, it works well alongside heavier classics because its humble oat base feels hearty without being overly rich.
6-Ingredient Oven Baked Thanksgiving Dessert
Servings: 8
Ingredients
3 cups dry uncooked rolled oats
2 large apples, peeled and diced
1 cup brown sugar
1 teaspoon ground cinnamon
1/2 cup unsalted butter, melted
2 cups milk
Directions
1. Preheat the oven to 350°F and lightly grease a metal roasting pan or similar oven-safe baking pan.
2. Pour the dry rolled oats into the pan, then scatter the diced apples evenly over the top.
3. In a bowl or large measuring cup, stir together the brown sugar, cinnamon, melted butter, and milk until well combined.
4. Pour the milk mixture evenly over the oats and apples, pressing lightly with the back of a spoon so the oats are moistened.
5. Bake for 35 to 40 minutes, until the apples are tender and the top is golden brown around the edges.
6. Let the dessert rest for 10 minutes before scooping and serving warm.
Variations & Tips
Add nuts: Stir in 1/2 cup chopped pecans or walnuts for a more traditional Thanksgiving flavor and a bit of crunch. Add them just before baking so they toast lightly on top.
Use pears instead of apples: Firm pears work beautifully here and give the dessert a slightly more delicate texture. Bosc or Anjou pears hold up especially well in the oven.
Make it richer: For a more dessert-like result, replace 1 cup of the milk with heavy cream. The finished texture will be more custardy and a little more luxurious.
Control the sweetness: If your apples are very sweet, you can reduce the brown sugar to 3/4 cup without losing the overall balance. A pinch of salt is also helpful if you want the flavors to taste more rounded.
Best baking pan tip: Because oats absorb liquid steadily, a shallow roasting pan helps the mixture bake more evenly than a very deep dish. If your pan is smaller and deeper, expect the baking time to run a few minutes longer.
