Ingredients You’ll Need

The ingredient list is refreshingly short and uses items you likely already have on hand. Fresh apples are the star here—choose varieties that hold their shape when baked like Granny Smith, Honeycrisp, or Gala.

For the topping, you’ll combine old-fashioned oats with brown sugar, cinnamon, and melted butter. This creates those signature crispy clusters that make apple crisp so addictive.

A touch of lemon juice brightens the apple filling, while cornstarch helps thicken the juices into a luscious sauce. Simple, wholesome ingredients that come together beautifully.

How to Make Deep Dish Apple Crisp

Save Pin

Start by preheating your oven to 350°F and greasing a 9×13-inch baking dish. This ensures your apple crisp won’t stick and makes cleanup a breeze.

Toss your sliced apples with sugar, flour, lemon juice, cinnamon, and nutmeg until everything is evenly coated. Spread this mixture into your prepared baking dish in an even layer.

In a separate bowl, mix oats, flour, brown sugar, cinnamon, and salt. Pour in the melted butter and stir until the mixture forms clumps—this is what creates those golden, crispy bits on top.

A simple, crowd-pleasing apple crisp with tender cinnamon apples and a buttery oat topping—no crust required. Perfect for fall gatherings or cozy weeknight desserts.

Ingredients

• Apple Filling:

• 8-10 medium apples (about 3 lbs), peeled, cored, and sliced ¼-inch thick

• ⅓ cup granulated sugar

• 2 tablespoons all-purpose flour

• 1 tablespoon fresh lemon juice

• 1½ teaspoons ground cinnamon

• ¼ teaspoon ground nutmeg

• Crisp Topping:

• 1½ cups old-fashioned rolled oats

• 1 cup all-purpose flour

• ¾ cup packed light brown sugar

• ½ teaspoon ground cinnamon

• ½ teaspoon salt

• ¾ cup (1½ sticks) unsalted butter, melted

Directions

• Preheat and Prep: Preheat oven to 350°F. Grease a 9×13-inch baking dish with butter or cooking spray.
• Make the Filling: In a large bowl, combine sliced apples, granulated sugar, flour, lemon juice, cinnamon, and nutmeg. Toss until apples are evenly coated. Spread mixture evenly in the prepared baking dish.
• Prepare the Topping: In a medium bowl, mix together oats, flour, brown sugar, cinnamon, and salt. Pour melted butter over the mixture and stir with a fork until clumps form and everything is moistened.
• Assemble: Sprinkle the oat topping evenly over the apples, covering them completely. Don’t pack it down—keep it loose for maximum crispiness.
• Bake: Bake for 45-55 minutes, until the topping is golden brown and the apple filling is bubbling around the edges. If the top browns too quickly, tent loosely with foil.
• Cool and Serve: Let cool for 15 minutes before serving. This allows the juices to thicken. Serve warm with vanilla ice cream or whipped cream.

Notes

• Apple Varieties: Best results with Granny Smith, Honeycrisp, Gala, or a combination. Avoid soft apples like Red Delicious.
  Make Ahead: Assemble the crisp up to 4 hours ahead, cover with foil, and refrigerate. Add 5-10 minutes to baking time if baking from cold.
• 
  Gluten-Free Option: Use gluten-free 1-to-1 baking flour and ensure oats are certified gluten-free.
  Add-Ins: Stir ½ cup chopped pecans or walnuts into the topping, or add ½ cup dried cranberries to the apple filling.

Baking Tips for Perfect Results

Sprinkle the oat topping evenly over the apples, making sure to cover them completely for maximum crispiness. Don’t pack it down—you want it loose so it can crisp up properly in the oven.

Bake for 45-55 minutes until the topping is golden brown and the apples are tender when pierced with a fork. If the top starts browning too quickly, tent it loosely with aluminum foil.

Let the crisp cool for at least 15 minutes before serving. This allows the juices to thicken up so you don’t end up with a soupy mess when you scoop it out.

Serving Suggestions

This apple crisp is incredible on its own, but a scoop of vanilla ice cream takes it to the next level. The cold, creamy ice cream melting into the warm apples is pure heaven.

You can also top it with whipped cream, a drizzle of caramel sauce, or even a dollop of Greek yogurt for breakfast. It’s versatile enough to work as dessert or a special morning treat.

Serve it warm in bowls with plenty of napkins nearby. The combination of tender apples, sweet syrup, and crunchy topping is seriously addictive.

Storage and Reheating

Save Pin

Store leftover apple crisp covered in the refrigerator for up to 5 days. The topping will soften slightly in the fridge, but reheating brings back most of that crispy texture.

To reheat, warm individual portions in the microwave for 30-60 seconds, or reheat the entire dish in a 350°F oven for 15-20 minutes. The oven method works best for restoring that crispy top.

You can also freeze baked apple crisp for up to 3 months. Let it thaw overnight in the fridge before reheating, or bake from frozen at 350°F for about 30-40 minutes.

Best Apples for Baking

Save Pin

Choosing the right apples makes a huge difference in texture and flavor. Firm, tart varieties like Granny Smith hold their shape well and balance the sweetness perfectly.

For more complex flavor, try mixing apple varieties—combine tart Granny Smith with sweet Honeycrisp or Fuji. This creates layers of flavor that make each bite interesting.

Avoid apples that turn mushy when baked, like Red Delicious or McIntosh, unless you prefer a softer, more sauce-like filling. Stick with baking apples for the best results.
