How to Make Easy Peach Crisp with Oats and Walnuts Recipe

Step 1: Prepare Your Oven and Skillet

Start by preheating your oven to 400°F and greasing a 10-inch cast-iron skillet. A cast-iron skillet is perfect for even heat distribution and gives a lovely rustic look when serving. Greasing it well ensures your crisp won’t stick, making cleanup a breeze.

Step 2: Mix the Peach Filling

In a large bowl, toss together the sliced ripe peaches with cornstarch, cane sugar, fresh lemon juice, and vanilla extract. This blend ensures your peaches are not just bursting with flavor but also thick and luscious once baked. The cornstarch thickens the filling, while lemon juice freshens up the sweetness and vanilla adds an inviting aroma.

Step 3: Make the Crunchy Topping

For the topping, combine rolled oats, almond flour, brown sugar, crushed walnuts, cinnamon, and sea salt in a medium bowl. Use your hands to work in the firm coconut oil or cold butter until the mixture is crumbly and evenly coated. This step is key—it’s what gives the crisp its delightful texture and rich flavor.

Step 4: Assemble and Bake

Scatter the peach filling evenly into your prepared skillet, then sprinkle the oat and walnut topping on top. Slide it into the oven and bake for 20 to 30 minutes until you see the fruit bubbly and the topping a gorgeous golden brown. Keep an eye on it toward the end to avoid burning the crunch.

Step 5: Cool and Serve

Once baked, let your peach crisp cool for about 5 minutes. This brief rest helps the juices to settle and keeps you from burning your mouth in excitement. Serve it warm and go wild with a scoop of vanilla ice cream for that perfect temperature and texture contrast.

Make Ahead and Storage

Storing Leftovers

If you have leftovers, cover the peach crisp tightly and store it in the refrigerator for up to 3 days. It saves beautifully and flavors will continue to meld, making every bite still feel fresh.

Freezing

To freeze, bake the crisp first and let it cool completely. Then wrap it tightly in plastic wrap and foil or place in an airtight container before freezing. It will keep well for up to 2 months. When you’re ready, thaw overnight in the fridge before reheating.

Reheating

Reheat your crisp in a 350°F oven for about 15-20 minutes or until warmed through and the topping is crisp again. Avoid microwaving if possible, as this can make the topping soggy.
