My blog recently celebrated its 8th anniversary, and I’m still passionate about sharing tested, approachable recipes. This Apple Crisp was one of the first recipes I published and remains a family favorite. I like to use a mix of Granny Smith and Pink Lady apples for a balanced tart-sweet filling, brightened with lemon and thickened slightly with cornstarch. The oat-based crumble is buttery with brown sugar and cinnamon for that classic autumn aroma.

This recipe is forgiving, easy to double or halve, and adapts well to dietary swaps—use gluten-free 1-to-1 flour or almond flour to make it gluten-free, and replace the butter with coconut oil for a dairy-free, vegan version.

Why you’ll love this recipe:

  • Tender apple pieces tossed with warm cinnamon and brown sugar under a golden, buttery oat crumble.
  • Uses a blend of baking apples for the best texture—holds shape while becoming tender and saucy.
  • Quick to prep (about 15 minutes) and can be assembled a day ahead.
  • Easy to adapt for gluten-free or vegan diets without changing the classic flavor.

Recipe ingredients

This easy apple crisp uses everyday pantry ingredients.

Apple crisp recipe ingredients
  • Apples: 3 pounds total. Baking apples hold their shape best—Granny Smith and Pink Lady are recommended; Jonagold, Braeburn, Honeycrisp, or Golden Delicious also work.
  • Unsalted butter: 1/2 cup. Substitute melted coconut oil for a dairy-free, vegan option.
  • All-purpose flour: 1 cup. Swap with gluten-free 1-to-1 flour or almond flour to make the topping gluten-free.
  • Rolled oats: 1 cup. Quick oats may be used in a pinch; do not use steel-cut oats. Use certified gluten-free oats if needed.
  • Granulated sugar: 1/2 cup.
  • Brown sugar: 1/3 cup, packed.
  • Cornstarch: 1 tablespoon to thicken the filling.
  • Cinnamon: 1 tablespoon ground, divided (2 tsp for filling, 1 tsp for topping).
  • Fresh lemon juice: 1 tablespoon to brighten flavor and prevent browning.
  • Salt: 1/4 teaspoon.

In a large bowl combine the apple chunks, granulated sugar, lemon juice, cornstarch and 2 teaspoons ground cinnamon. Toss until the apples are evenly coated. Grease a 9×13-inch baking dish and spread the filling in an even layer.

Prepare the crumble

How to make oatmeal crumble

Melt the butter, then stir in the rolled oats, flour, brown sugar, the remaining 1 teaspoon cinnamon and salt until crumbly and combined. If making vegan, use melted coconut oil in place of butter.

Bake the apple crisp

Scatter the crumble evenly over the apple filling. Bake at 350°F (175°C) for 50–60 minutes, until the filling is bubbly and the topping is golden. If the topping browns too quickly, tent loosely with foil after about 30 minutes. Let cool on a wire rack for at least 15 minutes before serving warm.

Recipe FAQs

What apples are best for apple crisp?

Use baking apples that hold their shape. Good choices include Granny Smith, Pink Lady, Jonagold, Braeburn, Honeycrisp and Golden Delicious. Mixing tart and sweet apples gives the best balance.

Can I make this recipe gluten free?

Yes. Replace the all-purpose flour with a gluten-free 1-to-1 flour or almond flour and use certified gluten-free oats.

Can apple crisp sit out overnight?

Store covered at room temperature up to 2 days, or refrigerate for 4–5 days. The crumble topping will become softer in the fridge.

How do you reheat apple crisp?

Reheat gently in the oven until warmed through for best texture, or use short bursts in the microwave if you’re in a hurry.

Recipe notes

  • Assemble the crisp ahead of time and refrigerate until 30–45 minutes before baking. Bring to room temperature for more even baking.
  • Leftovers keep up to 2 days at room temperature or up to 5 days refrigerated; the topping will soften in the fridge.
  • Substitute coconut sugar for granulated and brown sugars to make the crisp refined-sugar free.
  • Add chopped walnuts or pecans to the topping for extra crunch, or swap cinnamon for a chai-spice blend for a different flavor profile.
