# Crunchy Homemade Granola

Homemade granola is toasty, crunchy and lightly sweet, with big clusters you can eat by the handful. It takes 40 minutes and costs far less than a store-bought bag.

Press it down before baking and let it cool without stirring, and the clusters will hold together.

- Total time: 40 min (prep 10 min, cook 30 min)
- Serves: 12
- Per serving (estimated): 240 kcal, 6 g protein
- Cuisine: American. Category: Breakfast. Diet: vegetarian, dairy-free.

## Ingredients

- 3 cups (270 g) old-fashioned rolled oats
- 1 cup (130 g) mixed nuts, chopped
- 1/2 cup (60 g) pumpkin seeds
- 1/3 cup maple syrup
- 1/4 cup (60 ml) neutral oil or melted coconut oil
- 2 tbsp brown sugar
- 1 tsp cinnamon
- 1/2 tsp salt
- 1 tsp vanilla extract
- 1/2 cup (75 g) dried cranberries or raisins

## Method

1. Heat the oven to 325°F (160°C) and line a large baking sheet with parchment.
2. Mix the oats, nuts, pumpkin seeds, cinnamon and salt in a large bowl.
3. Warm the maple syrup, oil, brown sugar and vanilla in a small bowl or saucepan until smooth, then pour over the oat mix.
4. Stir well so every oat is lightly coated and slightly sticky.
5. Spread in an even layer on the baking sheet and press it down firmly with a spatula.
6. Bake for 25 to 30 minutes, stirring once at 15 minutes, until golden and fragrant. It will still feel soft.
7. Cool on the pan for 45 minutes without touching it so it hardens into clusters.
8. Break into chunks, stir in the dried fruit and store in a jar.

## Why it works

- Coating the oats in syrup and oil browns and crisps them as the sugars caramelize in the oven.
- Baking at 325°F dries the oats slowly, so they crisp without burning.
- Pressing the mix into a flat layer helps the sticky syrup glue the pieces together.
- Cooling without stirring lets the syrup harden into a candy-like binder that forms clusters.
- Adding dried fruit at the end keeps it chewy instead of hard and burnt.

## The science

- **Why granola crisps as it cools.** Hot syrup is soft and sticky. As it cools it loses heat and hardens into a glassy, brittle sugar glaze. If you stir during cooling, you break those new bonds as they form, and you end up with loose crumbs and dust instead of big, crunchy clusters.
- **Browning brings flavor.** As oats and nuts toast, their proteins and sugars react in the Maillard reaction, creating nutty, toasty flavors. This happens above about 300°F (150°C) at the surface, so a moderate oven browns the oats evenly without scorching the nuts or seeds.

## Tips

- Use parchment, not foil, so the granola releases easily.
- Do not skip the 45 minute cooling time; the clusters set as it cools.
- Taste for salt after cooling and sprinkle a pinch more if needed.

## Mistakes to avoid

- Stirring while the granola cools breaks up the clusters, so leave it alone.
- Adding dried fruit before baking makes it burnt and hard, so add it afterward.
- Baking too hot burns the sugar before the oats dry, so keep the oven at 325°F (160°C).

## Variations and swaps

- Chocolate coconut: add 1/2 cup coconut flakes before baking and dark chocolate chunks after.
- Peanut butter: whisk 1/4 cup peanut butter into the syrup.
- Tropical: use macadamias and add dried mango after baking.
- Swap maple syrup for honey; the granola browns faster, so check at 20 minutes.
- Swap nuts for more seeds such as sunflower seeds for a nut-free version.
- Swap oil for melted butter for a richer flavor.

## Storage

Store in an airtight jar at room temperature for up to 3 weeks, or freeze for 3 months. Serve with milk or yogurt.

## FAQ

**How do I get big clusters in granola?**

Press the mix firmly into a flat layer before baking and let it cool completely on the pan without stirring. Break it into chunks only after it is fully hard.

**How long does homemade granola last?**

It keeps for up to 3 weeks in an airtight container at room temperature. Freeze it for 3 months for longer storage.

**Why is my granola chewy and not crunchy?**

Chewy granola was underbaked or cooled in a humid spot. Bake until golden, cool fully and store in a sealed jar.

**Can I make granola without oil?**

You can, using a bit more syrup or nut butter, but oil helps the oats crisp and brown. Without it the granola will be harder and drier.

**Should I stir granola while baking?**

Stir once halfway through so the edges do not burn, then flatten it again. After that, leave it untouched while it cools.
