Grilled Peach & Walnut Crumble Recipe

Peaches: Fresh, ripe peaches are the star of this dish, providing juicy sweetness and a soft texture when grilled.

Walnuts: Chopped walnuts add a crunchy, nutty flavor that pairs perfectly with the peaches.

Rolled oats: These give the crumble topping a hearty texture and help hold everything together.

Brown sugar: Adds sweetness and a slight caramel flavor to the topping.

Butter: Melted butter binds the topping ingredients and creates a golden, crispy finish.

Cinnamon: A warm spice that enhances the flavor of the crumble and peaches.

Grilling the peach halves just right is a fun little trick that makes this Grilled Peach & Walnut Crumble really shine. Here’s how to get those perfect grill marks and tender fruit without turning your peaches into mush:

1. First, make sure your grill is hot enough—medium-high heat is just right. If it’s too cool, the peaches won’t get those nice marks or soften properly.
2. Place the peach halves cut side down on the grill. This helps caramelize the natural sugars and gives you those beautiful lines.
3. Don’t move them around too much. Let them sit for about 3-4 minutes so the heat can do its magic.
4. Flip them carefully using a spatula or tongs, and grill the other side for another 3-4 minutes until they’re tender but still hold their shape.

Doing this makes the peaches taste sweeter and gives a nice smoky flavor that makes the crumble topping even better. Plus, those grill marks make the dish look super inviting!

When I first tried grilling peaches, I was worried about them sticking to the grill or falling apart. A little trick I learned is to oil the grill grates lightly before putting the fruit on. It helps keep everything in one piece and makes flipping easier. Also, don’t rush the process—letting the peaches sit undisturbed is key to getting those perfect marks and soft texture.

Once you’ve got the grilling down, topping the peaches with the crunchy walnut and oat mixture and baking it all together brings the flavors to life. It’s a simple step that makes the crumble warm, golden, and ready to enjoy!

• Allow the grilled peaches and walnut crumble to cool completely at room temperature before storing. This prevents condensation and sogginess.
• Transfer the cooled dessert into an airtight container. If you have multiple layers, place a piece of parchment paper between them to avoid sticking.
• Store the container in the refrigerator for up to 3 days. The peaches will retain their flavor and the crumble topping will stay relatively crisp.
• For longer storage, place the cooled grilled peach & walnut crumble in a freezer-safe container or wrap it tightly in aluminum foil and then plastic wrap.
• Label the container with the date to keep track of freshness. The dessert can be frozen for up to 2 months.
• To reheat, preheat your oven to 350°F (175°C). If frozen, allow the crumble to thaw in the refrigerator overnight.
• Place the grilled peach & walnut crumble in an oven-safe dish and cover with aluminum foil to prevent the topping from burning.
• Bake for about 15-20 minutes or until heated through. Remove the foil for the last 5 minutes to crisp up the walnut topping.
• Enjoy your reheated grilled peach & walnut crumble with a scoop of vanilla ice cream or a dollop of whipped cream for an extra treat.

• Preheat your oven to 350°F (175°C). Place the leftover grilled peach & walnut crumble in an oven-safe dish. Cover it with aluminum foil to prevent the topping from burning. Bake for about 10-15 minutes until heated through.

• For a quicker method, use a microwave. Place a portion of the crumble in a microwave-safe dish. Cover it loosely with a microwave-safe lid or microwave-safe plastic wrap. Heat on medium power for 1-2 minutes, checking halfway through to ensure it heats evenly.

• If you prefer a crispier topping, use a toaster oven. Preheat the toaster oven to 350°F (175°C). Place the crumble in a toaster oven-safe dish and heat for about 10 minutes or until the topping is golden and the peaches are warmed through.

• For an added touch, reheat the crumble on the stovetop. Place a skillet over medium heat and add a small amount of butter. Once melted, add the crumble and cook, stirring occasionally, until heated through and the topping is crispy.

• If you have an air fryer, preheat it to 350°F (175°C). Place the crumble in an air fryer-safe dish and heat for about 5-7 minutes, checking halfway through to ensure it heats evenly and the topping remains crispy.
