🍁 Ingredients

You don't need much to make the perfect granola, only a few dry ingredients, a few wet ingredients, a sheet pan and an oven and voila — perfect granola every time. Here's an overview of the basic ingredients for this recipe:

  • Oats: any oats will do, but we like the large, old-fashioned oats because they make for a crunchier granola!
  • Walnuts: you'll need 1/2 cup of crushed walnuts for this recipe. If you don't have walnuts on hand, you can use other nuts and seeds (we love pumpkin seeds or sliced almonds).
  • Ground cinnamon: our favorite warm spice to use in fall-themed recipes.
  • Maple syrup: brings sweetness and helps ingredients stick together for the perfect granola!
  • Dried fruit: try raisins or dried cranberries; they bring a sweet, tart flavor to this crunchy snack.
  • Recommended tools: baking sheet, mixing bowl

🥣 How to make (step-by-step photos)

1️⃣ Step One: Preheat oven + prep ingredients

Start by preheating your oven to 250 degrees F.

In a mixing bowl, mix the oats, walnuts, and cinnamon together. Give it a stir, then combine with maple syrup to lightly coat the dry mixture.


2️⃣ Step Two: Bake granola until crunchy

Next, you'll spread the granola mix on a parchment paper-lined baking sheet. Roast in the oven until dry and crunchy, but not burnt. This will take about 20 minutes.


3️⃣ Step Three: Let granola cool + add raisins

Finally, take the granola out of the oven. Set it aside and let it cool completely.

Once the granola is cooled, toss it with raisins or other dried fruit. Enjoy!

Important! Do not bake granola mix with raisins; only mix them in after baking. Baked raisins burn easily.

❓ Recipe questions + quick tips

What are the health benefits of walnuts?

There are a variety of health benefits associated with eating walnuts. What really makes them shine is their healthy fat content, which is good for the heart, supports brain health, and more. Additionally, walnuts are a source of fiber, disease-fighting antioxidants, and vitamins and minerals like Vitamin E and manganese.

Why is my granola not crunchy?

To get the perfect crunch in granola, you need to mix dry oats with a small amount of liquid. Liquid sweeteners like maple, agave, and honey add a slight dampness when mixed with oats, and help to make it crunchier. It is also a good idea to roast granola on low heat for about 20 minutes to make it as crunchy as possible.

Is eating homemade granola healthy?

Homemade granola is typically made from healthy ingredients, including oats, nuts, seeds, and dried fruit. While these provide fiber, vitamins, minerals, and protein, granola can be high in calories and is easy to overeat. We suggest eating granola in moderation; a handful is a reasonable portion size. You are also better off making granola from scratch because you can control the types of ingredients and the amount of sugar that's in it.


🥞 How to serve

There are so many possibilities for how you can serve walnut granola. Here are a few of our favorite ways:

  • Have as a snack on its own. Grab a handful of granola and enjoy as a simple, balanced snack between meals!
  • As a breakfast topping. You can't go wrong with adding granola to breakfast staples like yogurt parfaits, oatmeal bowls, and even pancakes and waffles. It can even be used as a topping for smoothies and fruit bowls!
  • Enjoy as cereal. Mix some walnut granola with your favorite milk or milk alternative for a crunchy cereal.
  • Dessert mix-in. Top cake, brownies, cookies, or ice cream with a couple of spoonfuls of granola.
  • Get creative with toppings. Make this recipe your own by adding different types of nuts (pecans, pistachios, coconut), seeds (sunflower seeds, flax seeds), spices (vanilla, nutmeg, pumpkin spice), or sweets (honey, agave, brown sugar, raisins).

🧊 How to store

You're going to love this homemade granola so much, it's unlikely that you'll have leftovers! If you do, make sure to keep it in a sealable container and eat within one month. While it could stay fresh for longer, granola tends to go stale the longer that it's stored.

Granola can be kept in the refrigerator, but it will keep its quality when stored at room temperature. We do not suggest storing granola in the freezer.

♻️ Sustainable kitchen tips
