Plate · Cast Iron Skillet Granola

First written down, Summer 2012

Most camping snacks are either purchased in crinkly bags or require an oven, which is useless when you are standing in a forest. The common failure mode of making granola outdoors is attempting to bake it in a covered Dutch oven over coals, which almost always results in a scorched bottom layer and pale, steamed oats on top. The solution is to abandon the oven concept entirely and toast the mixture in an open skillet over a camp stove, stirring constantly until the sugars caramelize and the oats turn deeply golden.

This method relies on the direct, conductive heat of cast iron. By melting the butter and honey first, you create a hot syrup that coats the oats and nuts evenly. As the moisture cooks off, the sugars begin to toast the grains from the outside in. The addition of dried fruit must happen off the heat; adding it while the pan is over the flame will turn raisins or cherries into bitter, blackened pebbles.

This granola takes about fifteen minutes of active attention and cools into clusters as it sits. It can be eaten immediately with powdered milk and water, or stored in a sealed container for the duration of the trip. It serves as a dense, high-energy breakfast or a handful-by-handful snack while hiking.

What you need

Ingredients

Measurements

Metric converts only measures that are mathematically safe. Density-dependent cups stay as Nicole wrote them.

Scale the batch

6 cups

  • 4 cups old-fashioned rolled oats
  • 1 cup sliced almonds
  • 1/2 cup raw pumpkin seeds
  • 1/2 cup unsalted butter
  • 1/2 cup honey
  • 1 teaspoon kosher salt
  • 1 teaspoon ground cinnamon
  • 1 cup dried tart cherries

How it goes

Method

Read the whole thing once before you start. Nothing here is difficult, but the timing is unforgiving at the end.

  1. Melt the butter and honey

    Place a large cast iron skillet over a camp stove on medium-low heat. Add the butter, honey, salt, and cinnamon. Stir until the butter is completely melted and the mixture begins to bubble gently at the edges.

  2. Coat the dry ingredients

    Pour the oats, almonds, and pumpkin seeds into the skillet. Use a wooden spoon or heatproof spatula to fold the mixture repeatedly until every oat is coated in the butter and honey syrup and no dry spots remain.

  3. Toast the mixture

    Cook the granola over medium-low heat, stirring constantly and scraping the bottom of the skillet to prevent burning. Continue this for 10 to 15 minutes. The doneness cue is visual and olfactory: the oats will turn a deep, even golden brown and smell strongly of toasted nuts and caramelized sugar.

  4. Remove from heat

    Immediately turn off the stove and carefully move the skillet to a heatproof surface. The cast iron will retain significant heat and continue to cook the granola if left on the warm burner.

  5. Add the dried fruit

    Stir the dried cherries into the hot granola. Do not return the pan to the heat. Flatten the mixture slightly with the back of your spoon and let it cool completely in the skillet, about 20 minutes, which allows it to form clusters.

Equipment

All 2 of these change the result. Nothing here is a brand recommendation — the spec is what matters.

  1. Large cast iron skillet

    The recipe relies on cast iron's heat retention to toast the oats and nuts evenly without hot spots; a thin pan will scorch the sugar quickly even with constant stirring.

    What matters
    A large (10- or 12-inch) cast iron skillet with a smooth cooking surface and at least a 3-quart capacity for the listed quantity.
  2. Wooden spoon or heatproof spatula

    Constant stirring and scraping are mandatory to prevent the sugar and oats from burning; a heatproof tool lets you do this continuously without melting.

    What matters
    Sturdy wooden spoon or heatproof silicone spatula long enough to reach the skillet center and robust enough to scrape the bottom repeatedly.

Cook's notes

What we would tell a friend

  • Do not use quick oats or steel-cut oats; quick oats will turn to mush, and steel-cut oats will remain too hard to eat without boiling.
  • If your camp stove runs hot, keep the flame as low as possible. Sugar burns quickly, and constant stirring is mandatory.
  • Store the cooled granola in an airtight container or heavy-duty zip-top bag. It will keep at ambient outdoor temperatures for up to two weeks.
  • Any dried fruit can be substituted for the cherries, but it must always be added off the heat to prevent scorching.
