Brown Butter Apple Crisp with Oats & Orange Zest
Apple crisp has been one of my go-to desserts for years – simple, cozy, and always a favorite when apples are in season. It’s the kind of dessert that feels just as right on a quiet weeknight as it does on a crowded fall table.
What sets this version apart is the topping. Browning the butter adds a deep, nutty richness, while a touch of orange zest lifts everything just enough to keep it from feeling heavy. It’s still familiar and comforting, but with a little extra something.
And if you’re in full apple season mode, you might also enjoy my Easy Spiced Baked Apples for a simple fall dessert, my Apple Marzipan Babka for something a little more show-stopping, or my Baked Apple Cider Donuts, an apple season must in my kitchen.

How to make Brown Butter Apple Crisp
Prep the Apples
Preheat your oven to 175°C (350°F) and lightly grease a 9×9-inch (23×23 cm) baking dish.
In a large bowl, toss the sliced apples with lemon juice, sugar, flour, and spices until evenly coated. Spread the mixture into the prepared baking dish, making sure the apples are fairly level.
Brown the Butter
Place the butter in a light-colored saucepan over medium heat. Let it melt, then continue cooking, swirling occasionally, until it turns golden brown and smells nutty – about 3–5 minutes.
Watch closely during the final minute; browned butter goes from perfect to burnt quickly. Remove from the heat and immediately stir in the orange zest. Let it cool slightly for about 5 minutes.
Make the Crisp Topping
In a medium bowl, combine the oats, flour, brown sugar, salt, and spices. Pour in the warm brown butter and orange zest mixture, stirring until clumps form. Fold in the nuts, if using.
Assemble & Bake
Sprinkle the topping evenly over the apples.
Bake uncovered for 40–45 minutes, or until the topping is golden brown and the apple filling is bubbling around the edges. Let the brown butter apple crisp rest for 10–15 minutes before serving.

Frequently Asked Questions
What apples work best for this brown butter apple crisp?
A mix of sweet and tart apples is ideal. Honeycrisp, Cortland, Granny Smith, and McIntosh all work well.
Can I make this brown butter apple crisp ahead of time?
Yes. You can assemble the crisp a few hours ahead and refrigerate it unbaked. Bake just before serving for the best texture.
Can I reheat leftovers?
Absolutely. Reheat your brown butter apple crisp in a low oven until warmed through, or enjoy it cold straight from the fridge (also very good).
Can I add other fruits?
Yes! Pears, cranberries, or even a pear-apple combo work beautifully with the warm spices of this recipe.
Can I freeze apple crisp?
Yes. This brown butter apple crisp freezes well either baked or unbaked. To freeze unbaked, assemble the crisp, cover tightly, and freeze for up to 3 months. Bake straight from frozen, adding an extra 10–15 minutes. To freeze baked crisp, let it cool completely, then wrap well and freeze. Thaw overnight in the fridge and reheat in the oven until warmed through.
Why is my apple crisp watery?
Apple crisp can turn watery if the apples release a lot of juice or if it hasn’t baked long enough. Using the right amount of flour in the filling helps thicken the juices, and letting the crisp rest for 10–15 minutes after baking allows the filling to set properly. If your apples are especially juicy, baking a few extra minutes usually does the trick.
