Ingredients
For the Apple Filling:
- 6 medium apples (Granny Smith, Honeycrisp, or a mix), peeled, cored, and sliced thin
- 2 tbsp lemon juice
- ½ cup granulated sugar
- 2 tbsp all-purpose flour (or cornstarch for gluten-free option)
- 1 tsp ground cinnamon
- ¼ tsp ground nutmeg
- Pinch of salt
For the Oatmeal Crisp Topping:
- 1 cup old-fashioned rolled oats
- ¾ cup all-purpose flour
- ¾ cup packed light brown sugar
- ½ tsp ground cinnamon
- ¼ tsp salt
- ½ cup (1 stick) unsalted butter, cold and cut into small cubes
(Optional: ½ cup chopped pecans or walnuts for added crunch.)
Cooking Directions (Overview)
- Toss apples with sugar, spices, and flour.
- Mix oats, flour, sugar, and butter to form a crumbly topping.
- Layer apples in a baking dish, sprinkle with topping, and bake until golden and bubbly.
Step-by-Step Preparation Method
Step 1: Prepare the Apples
- Preheat oven to 350°F (175°C).
- Peel, core, and thinly slice the apples. Place them in a large mixing bowl.
- Add lemon juice to prevent browning and toss to coat.
- Sprinkle granulated sugar, flour, cinnamon, nutmeg, and a pinch of salt over the apples. Toss until evenly coated.
Step 2: Make the Crisp Topping
- In another bowl, combine oats, flour, brown sugar, cinnamon, and salt.
- Add the cold, cubed butter.
- Using a pastry cutter, fork, or your fingers, work the butter into the mixture until it resembles coarse crumbs with some pea-sized pieces.
- Stir in chopped nuts if using.
Step 3: Assemble the Apple Crisp
- Grease a 9×13-inch baking dish (or similar size).
- Spread the apple mixture evenly on the bottom.
- Sprinkle the oat topping evenly over the apples, covering them fully.
Step 4: Bake
- Bake in the preheated oven for 45–50 minutes, or until the topping is golden brown and the filling is bubbling.
- If the topping browns too quickly, tent with foil during the last 10 minutes.
Step 5: Cool and Serve
Remove the crisp from the oven and let it rest for at least 10–15 minutes before serving. This allows the juices to thicken slightly.

How to Serve
Serve Apple Crisp warm, topped with:
- A scoop of vanilla ice cream for a classic combo
- A dollop of whipped cream for a light, airy finish
- A drizzle of caramel sauce for extra indulgence
- A sprinkle of cinnamon or toasted nuts for elegance
It’s delicious warm but also tasty at room temperature or chilled the next day.
Recipe Tips
- Apple Choice Matters: Use a mix of tart (Granny Smith) and sweet (Honeycrisp or Fuji) apples for balanced flavor.
- Cold Butter = Crispy Topping: Keep the butter cold to ensure a crumbly, crisp texture.
- Slice Evenly: Uniform apple slices bake evenly.
- Let It Rest: Allow the crisp to sit after baking so the filling sets slightly.
- Make Ahead: You can prepare the topping and apple filling separately up to a day in advance and assemble before baking.
Variations
- Pear-Apple Crisp: Mix in sliced pears for a lighter, fragrant twist.
- Nutty Crisp: Add almonds, pecans, or walnuts to the topping for crunch.
- Berry Apple Crisp: Add a cup of fresh or frozen berries to the filling for tartness.
- Coconut Oat Topping: Replace some oats with shredded coconut for a tropical spin.
- Gluten-Free: Use almond flour or a certified GF flour and GF oats.
- Dairy-Free: Substitute butter with vegan margarine or coconut oil.
Freezing & Storage
- Refrigeration: Store cooled apple crisp covered in the refrigerator for up to 4 days. Reheat in the oven at 350°F for 10–15 minutes to restore crispness.
- Freezing (Unbaked): Assemble the crisp, cover tightly with plastic wrap and foil, and freeze for up to 3 months. Bake straight from frozen, adding 10–15 extra minutes.
- Freezing (Baked): Cool completely, wrap well, and freeze for up to 2 months. Thaw overnight in the fridge and reheat in the oven.
Special Equipment Needed
- 9×13-inch baking dish (or similar)

FAQ
Q1: Can I make this apple crisp ahead of time?
Yes! You can assemble it a day in advance, refrigerate it, and bake just before serving. Or bake it ahead and reheat in the oven.
Q2: Can I use quick oats instead of old-fashioned oats?
Quick oats work, but the topping will be softer. For a classic crisp texture, old-fashioned oats are best.
Q3: What apples are best?
Granny Smith, Honeycrisp, Fuji, or a mix of tart and sweet varieties provide the best flavor and texture.
Q4: Why is my topping soggy?
Too much butter or not enough baking time can cause sogginess. Bake until the topping is golden and crisp.
