Ingredients for Apple Crisp

For the Apple Filling

• 6 medium apples, peeled, cored, and thinly sliced
• 2 tbsp granulated sugar
• 2 tbsp brown sugar
• 1 tbsp all-purpose flour
• 1 tsp ground cinnamon
• ½ tsp vanilla extract
• 1 tbsp lemon juice
• ¼ tsp ground nutmeg
• Pinch of salt

For the Crisp Topping

• 1 cup old-fashioned rolled oats
• ¾ cup all-purpose flour
• ½ cup brown sugar
• ½ tsp ground cinnamon
• ¼ tsp salt
• ½ cup unsalted butter, melted
• ½ cup chopped walnuts or pecans, optional

How to Make Apple Crisp

1. Prepare the Apples

Preheat your oven to 350°F (175°C).

Peel, core, and slice the apples into thin, even pieces. Add them to a large mixing bowl.

Add the granulated sugar, brown sugar, flour, cinnamon, vanilla extract, lemon juice, nutmeg, and salt.

Gently toss everything together until the apples are evenly coated.

2. Prepare the Crisp Topping

In another bowl, combine the rolled oats, flour, brown sugar, cinnamon, and salt.

Pour in the melted butter and mix until the ingredients form a crumbly mixture.

If you like extra crunch, stir in chopped walnuts or pecans.

3. Assemble the Apple Crisp

Lightly grease an 8×8-inch baking dish or a similar-sized baking dish.

Spread the seasoned apples evenly across the bottom.

Sprinkle the oat topping generously over the apples, making sure the fruit is covered evenly.

4. Bake

Place the baking dish in the preheated oven and bake for approximately 35–45 minutes, or until the apples are tender and bubbling around the edges and the topping is golden brown.

If the topping begins to brown too quickly, loosely cover the dish with aluminum foil for the remaining baking time.

5. Cool and Serve

Allow the apple crisp to rest for about 10 minutes before serving.

Serve warm with vanilla ice cream, whipped cream, or a drizzle of caramel sauce.

Best Apples for Apple Crisp

The type of apples you use can change the flavor and texture of your dessert.

Good choices include:

• Granny Smith – tart and firm
• Honeycrisp – sweet, crisp, and juicy
• Pink Lady – balanced sweet-tart flavor
• Braeburn – flavorful and firm
• Gala – naturally sweet and mild

You can also combine two varieties for a more interesting flavor.

Tips for the Best Apple Crisp

Slice the Apples Evenly

Try to slice the apples into similar-sized pieces so they cook evenly. Very thick pieces may remain firm while thinner pieces become too soft.

Don’t Skip the Lemon Juice

A little lemon juice balances the sweetness and helps bring out the natural apple flavor.

Use Old-Fashioned Oats

Old-fashioned rolled oats provide a heartier, crunchier topping than quick oats.

Let It Rest Before Serving

The filling thickens slightly as the crisp cools. Letting it rest for about 10 minutes makes it easier to serve.

Add Nuts for Extra Crunch

Chopped pecans or walnuts are optional but add wonderful texture to the buttery oat topping.

Easy Apple Crisp Variations

Caramel Apple Crisp

Drizzle caramel sauce over the baked apple crisp just before serving for a delicious caramel-apple combination.

Apple Cranberry Crisp

Add fresh or dried cranberries to the apple filling for a sweet and tart variation.

Apple Pecan Crisp

Add chopped pecans to the topping for extra crunch and a rich nutty flavor.

Gluten-Free Apple Crisp

Replace the all-purpose flour with a gluten-free flour blend and make sure your oats are certified gluten-free.

Dairy-Free Apple Crisp

Use a plant-based butter alternative instead of regular butter.

What to Serve with Apple Crisp

Warm apple crisp is delicious on its own, but these toppings make it even better:

• Vanilla ice cream
• Whipped cream
• Caramel sauce
• Cinnamon whipped cream
• Greek yogurt
• Chopped toasted nuts

For the classic combination, serve it warm with a scoop of vanilla ice cream. The cold, creamy ice cream melts over the warm apples and crunchy topping.

How to Store Apple Crisp

Allow the apple crisp to cool completely before covering it.

Store leftovers in the refrigerator in an airtight container or covered baking dish for up to 4 days.

To bring back some of the crisp texture, reheat individual portions in the oven or air fryer rather than the microwave.

Can You Freeze Apple Crisp?

Yes. Apple crisp can be frozen before or after baking.

For baked apple crisp, allow it to cool completely, cover it tightly, and freeze.

Thaw it in the refrigerator before reheating in a 350°F (175°C) oven until warmed through.

Frequently Asked Questions

What is the difference between apple crisp and apple crumble?

The names are sometimes used interchangeably, but traditionally an apple crisp contains oats in the topping, giving it a crunchier texture. A crumble generally has a streusel-like topping made primarily with flour, butter, and sugar.

Should I peel apples for apple crisp?

Peeling is recommended if you want a softer, smoother filling. However, you can leave the skins on if you prefer more texture and fiber.

Why is my apple crisp watery?

Apples naturally release liquid as they bake. Using a little flour or cornstarch in the filling helps thicken the juices. Allowing the crisp to rest after baking also gives the filling time to set.

Can I make apple crisp ahead of time?

Yes. You can assemble the apple crisp several hours ahead and refrigerate it until you’re ready to bake. For the crispiest topping, bake it shortly before serving.

Can I use oats in apple crisp?

Yes. Old-fashioned rolled oats are ideal because they create a hearty, crunchy topping.

Can I make apple crisp without nuts?

Absolutely. Nuts are optional. Simply leave them out for a classic oat topping.
