Ingredients You’ll Need

For the Fruit Filling

• 3 cups firm, tart apples, peeled and sliced – Honeycrisp, Granny Smith, or Braeburn are excellent choices because they hold their shape while baking and provide a nice tart contrast to the pears.
• 3 cups ripe but firm pears, peeled and sliced – Bosc or Anjou pears work especially well, adding natural sweetness and a soft, juicy texture without becoming mushy.
• Brown sugar – Sweetens the fruit while adding warm caramel notes. Taste your fruit first and reduce the sugar slightly if your pears are especially sweet.
• Ground cinnamon – Adds classic fall flavor that complements both apples and pears.
• Ground nutmeg – Brings subtle warmth and depth to the filling.
• Cornstarch (1–2 tablespoons) – Thickens the fruit juices and prevents a watery, soggy filling.

For the Walnut Crisp Topping

• 1 cup old-fashioned rolled oats – Creates the signature crisp texture.
• ½ cup all-purpose flour – Helps bind the crumb topping together.
• ½ cup chopped English walnuts – Adds a buttery, nutty crunch that pairs perfectly with the fruit.
• ½ cup brown sugar – Sweetens the topping while encouraging a beautifully golden crust.
• ½ cup cold butter, cubed – Creates a rich, crumbly topping that bakes up crisp and golden. Keep the butter cold for the best texture.

Equipment You’ll Need

• 9×9-inch baking dish
• Large mixing bowl
• Medium mixing bowl
• Measuring cups and spoons
• Sharp knife
• Vegetable peeler
• Cutting board
• Pastry cutter or fork (or your fingertips for mixing the topping)
• Rubber spatula
• Oven

How to Make Walnut Pear Apple Crisp

Cool before serving.
Let the crisp rest for at least 15 minutes before serving. This allows the filling to thicken and makes serving much easier.

Preheat the oven.
Set your oven to 350°F (175°C) and lightly grease a 9×9-inch baking dish.

Prepare the fruit.
Peel and slice the apples and pears into evenly sized slices so they cook at the same rate. Aim for a 50/50 ratio of apples to pears for the best flavor balance.

Mix the filling.
In a large bowl, toss the sliced fruit with the brown sugar, cinnamon, nutmeg, and 1–2 tablespoons of cornstarch until evenly coated. The cornstarch helps thicken the juices during baking.

Fill the baking dish.
Spread the fruit mixture evenly into the prepared baking dish.

Make the crisp topping.
In a separate bowl, combine the rolled oats, flour, chopped English walnuts, and brown sugar. Add the cold butter and cut it into the dry ingredients using a pastry cutter, fork, or your fingertips until coarse crumbs form.

Assemble the crisp.
Sprinkle the walnut topping evenly over the fruit, covering it completely without pressing it down.

Bake.
Bake uncovered for 40–45 minutes, or until the topping is golden brown and the fruit filling is bubbling around the edges.

Tips for the Best Walnut Pear Apple Crisp

1. Use a 50/50 mix of apples and pears.
   Equal parts tart apples and sweet pears create the perfect balance of flavor and texture.
2. Choose firm fruit.
   Honeycrisp, Granny Smith, or Braeburn apples paired with firm Bosc or Anjou pears hold their shape well during baking and prevent a mushy filling.
3. Don’t skip the cornstarch.
   Toss the fruit with 1–2 tablespoons of cornstarch (or tapioca starch) to thicken the juices and prevent a soggy crisp.
4. Use cold butter for the topping.
   Cold butter creates coarse crumbs that bake into a light, crispy topping. Soft or melted butter can make the topping greasy instead of crunchy.
5. Choose English walnuts.
   English walnuts have a mild, buttery flavor that complements the fruit without overpowering it. Black walnuts have a much stronger taste and are best if you prefer a bold, rustic flavor.
6. Bake uncovered.
   Covering the dish traps steam, which softens the topping. Baking uncovered helps it become beautifully golden and crisp.
7. Let it cool before serving.
   Allow the crisp to rest for 15 minutes after baking. This gives the filling time to thicken, making it easier to serve.
8. Taste the fruit before mixing.
   Since pears vary in sweetness, taste a slice before adding the sugar. If they’re especially sweet, reduce the sugar slightly for a better-balanced dessert.

Storage & Make-Ahead

Refrigerator

Allow the crisp to cool completely before covering it tightly or transferring it to an airtight container. Store it in the refrigerator for up to 4 days.

Freezer

For longer storage, freeze the baked crisp for up to 3 months. Thaw it overnight in the refrigerator before reheating.

Reheating

To restore the crisp topping, reheat in a 350°F oven for 10–15 minutes until warmed through. While the microwave is faster, it will soften the topping instead of keeping it crisp.

Make-Ahead Tips

• Assemble the fruit filling and topping up to 24 hours in advance.
• For the crispiest topping, store the fruit filling and topping separately in airtight containers and combine them just before baking.
• You can also bake the crisp completely ahead of time and refrigerate it until you’re ready to serve. Simply reheat it in the oven to refresh the crunchy topping.

Easy Variations

• Make it oat-free. Replace the rolled oats with extra chopped walnuts or almond flour for a delicious oat-free crisp topping.
• Swap the walnuts. If you prefer a sweeter, buttery nut flavor, substitute the walnuts with pecans. They work beautifully with both apples and pears.
• Use different apple varieties. Try Honeycrisp for balanced sweetness, Granny Smith for a tangy contrast, or Braeburn for a naturally sweeter crisp.
• Adjust the sweetness. If your pears are especially ripe and sweet, reduce the sugar by about 1 tablespoon to keep the flavors balanced.
• Add extra warming spices. Enhance the filling with a pinch of ground ginger, allspice, or cardamom alongside the cinnamon and nutmeg for even more cozy fall flavor.
• Make it vegan. Replace the butter with a vegan butter stick or coconut oil for a dairy-free version that still bakes up beautifully.

What to Serve With

This warm walnut pear apple crisp is delicious on its own, but these pairings make it even more irresistible:

• Vanilla bean ice cream
• Fresh whipped cream
• Caramel sauce
• Greek yogurt for a lighter dessert
• Vanilla custard
• Hot coffee or espresso
• Chai tea
• Hot apple cider
• Maple-sweetened whipped cream
• Toasted walnuts sprinkled over each serving for extra crunch

Frequently Asked Questions

What are the best apples for walnut pear apple crisp?

Firm varieties like Honeycrisp, Granny Smith, and Braeburn are excellent because they hold their shape during baking and balance the sweetness of the pears.

What kind of pears work best?

Firm pears such as Bosc or slightly underripe Anjou pears provide the best texture and don’t become overly soft while baking.

Why is my fruit filling watery?

Pears release a lot of juice as they bake. Tossing the fruit with 1–2 tablespoons of cornstarch or tapioca starch helps thicken the filling and prevents a soggy crisp.

Can I make walnut pear apple crisp ahead of time?

Yes. Assemble the filling and topping up to 24 hours in advance. For the crispiest topping, keep them in separate airtight containers and combine them just before baking.

Can I use canned pears?

Yes. Drain them well before using, and since canned pears release less liquid than fresh pears, you can reduce or skip the cornstarch.

How long does walnut pear apple crisp last?

Store leftovers in the refrigerator for up to 4 days or freeze for up to 3 months. Reheat in a 350°F oven for 10–15 minutes to restore the crisp topping.

I love this walnut pear apple crisp because it combines the tartness of apples, the natural sweetness of pears, and the rich crunch of walnuts into one cozy dessert that’s perfect for fall.
