Chestnut Granola Recipe: Proof Chestnuts Belong on Your Breakfast Table

This homemade chestnut granola recipe folds Treeborn’s roasted chestnut chips into a crunchy oat base — naturally sweet, fiber-rich, and ready in under two hours.

Chestnuts don’t wait for you to be ready. By the time most people start searching for what to do with them, it’s December, the good batches are already claimed, and we’re telling people we’ll see them next year.

That’s the part nobody plans for, so we’ve made a habit of getting ahead of it — starting with the same granola we make almost every week at EBB Farms.

Why Treeborn’s Chestnut Chips Make This Easier

Welcome to the Chestnut Kitchen, where we test what a modern chestnut pantry actually looks like. For this batch, we stirred Oven Roasted Chestnut Chips from Treeborn Products into a classic oat granola after it came out of the oven, so the chips keep their bite instead of going soft. Treeborn’s chips arrive already peeled, sliced, and oven-baked — no scoring, soaking, or burnt fingers required, which makes this one of the easiest ways to bake with chestnuts at home. That’s the kind of shortcut this industry needs more of: proof that chestnuts can move from orchard to pantry shelf without an asterisk attached.

Is Chestnut Granola Healthy? What Chestnuts Bring to the Bowl

We won’t pretend chestnuts are a protein food — they’re not. Gram for gram, they carry a fraction of the protein you’d get from the almonds or pecans already in this recipe. What chestnuts are genuinely good at is different: they’re one of the only low-fat, carbohydrate-forward nuts out there, they carry a real amount of fiber, and they hold roughly four times the vitamin C of a peanut. One study comparing eleven types of nuts found chestnuts had the highest polyphenol content of the bunch — the antioxidant compounds tied to lower inflammation.

So the protein in this granola is doing its job — it’s just coming from the almonds, pecans, chia, and hemp seeds, not the chestnuts. The chestnuts are pulling different weight: steady carbohydrate energy, fiber, and a sweetness that’s real, not added. That combination is what makes the bowl feel complete instead of just crunchy.

There’s also a strange little fact about chestnut storage worth knowing: the starch in a chestnut slowly converts to sugar the longer it’s kept cool, the same way an old potato tastes sweeter than a fresh one. Chestnuts you order now have months to make that shift before the holidays — which is one more reason getting ahead of the season pays off in flavor, not just supply.

How to Make Homemade Chestnut Granola

We built this off our regular oat granola base and reworked it around the chips. Makes about 5 cups — enough for a week of breakfasts, or one very good gift.

Ingredients

Bake in:

• 2 cups rolled oats
• 1 cup unsweetened shredded coconut
• 1/2 cup pecans, chopped
• 1/2 cup whole almonds
• 2 tablespoons chia seeds
• 2 tablespoons hemp seeds
• 2 tablespoons ground flaxseed
• 1 teaspoon ground cinnamon
• 3/4 teaspoon salt
• 2 tablespoons organic sunflower oil
• 1/4 cup 100% maple syrup
• 1 teaspoon vanilla extract

Stir in after cooling:

• 1 cup Treeborn Oven Roasted Chestnut Chips, roughly chopped
• 1/2 cup raisins
• 1/2 cup dried cranberries (optional)

Instructions

1. Preheat the oven to 250°F and line a rimmed baking sheet with parchment.
2. Combine the dry bake-in ingredients in a large bowl.
3. Whisk the sunflower oil into the maple syrup in a small saucepan, bring to a simmer, then remove from heat and stir in the vanilla.
4. Pour over the oat mixture and mix until everything’s coated.
5. Spread in a single layer and bake 90 minutes, stirring every 15, until golden.
6. Cool completely, then stir in the chestnut chips, raisins, and cranberries — adding them after baking is what keeps every bite crunchy instead of soft.

Why We Make This Chestnut Granola Every Week

This isn’t a batch we made once for the photos. At EBB Farms, we go through this granola almost every week — breakfast on the porch, a scoop over yogurt between chores. It’s just what’s in the kitchen now.

Get Ahead of December

Almost nobody looks for chestnuts until the holidays are already on top of them, and by then we’ve usually sold through what we grew. Mid-July feels early to be thinking about Christmas — but it’s exactly when pre-orders open, and it means your chestnuts have all summer and fall to reach that deeper, sweeter flavor before they ever hit your kitchen.

Pre-order your fresh chestnuts from here at EBB Farms. Grab a bag of chips from Treeborn while you’re at it, bake a batch, and tell us how it turned out.
