Ingredients You Need
Apples
- 6 medium apples, about 2 to 2½ pounds
- Use a mix of tart and sweet apples for best flavor.
- Good options: Granny Smith, Honeycrisp, Pink Lady, Braeburn, or Fuji.
- Avoid only super-soft apples, since they turn mushy.
Filling ingredients
- 1/3 cup granulated sugar
- 1/4 cup light brown sugar, packed
- 2 tablespoons all-purpose flour
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg (optional but tasty)
- 1/8 teaspoon ground cloves (optional, very strong, use lightly)
- 1/4 teaspoon fine sea salt
- 1½ teaspoons vanilla extract
- 1 tablespoon lemon juice (fresh or bottled)
The flour thickens the juices so the filling turns saucy instead of watery. Lemon juice brightens the flavor and keeps apples from browning too fast.
Oat crisp topping
- 3/4 cup old-fashioned rolled oats
- Use old-fashioned oats, not instant or quick oats, for better texture.
- 3/4 cup all-purpose flour
- 1/2 cup light brown sugar, packed
- 1/4 cup granulated sugar
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon fine sea salt
- 1/2 cup cold unsalted butter, cut into small cubes
- If you only have salted butter, use it and reduce the added salt slightly.
You can swap up to half the all-purpose flour with whole wheat flour for a nuttier flavor. You can also add 1/2 cup chopped nuts such as pecans or walnuts if you like extra crunch.
Optional add-ins
- 1/2 cup chopped pecans or walnuts
- 1/3 cup raisins or dried cranberries
- 1 tablespoon maple syrup in the filling for deeper flavor
Pantry shortcuts and brand notes
You can use pre-cut apple slices from the produce section to save time, just slice them thinner if they look chunky. Any store brand sugar, flour, and oats work fine in this apple crisp recipe with oats, so you do not need anything fancy. If you keep apple pie spice on hand, you can use 1½ teaspoons of that instead of the cinnamon, nutmeg, and cloves.
Equipment list
- 9×9 inch baking dish or similar size (an 8×8 pan also works, just bake a little longer)
- Large mixing bowl
- Medium mixing bowl
- Cutting board and sharp knife
- Vegetable peeler
- Measuring cups and spoons
- Fork or pastry cutter for the topping
- Rubber spatula or wooden spoon
Tips & Mistakes
- Slice apples evenly so they bake at the same rate and stay tender, not crunchy in some bites and mushy in others.
- Peel the apples if you want a softer filling, or leave the peel on if you like more texture and extra fiber.
- Toss apples with the sugar, spices, and flour thoroughly so every slice gets coated and the filling thickens evenly.
- Keep the butter cold for the topping so it stays crumbly and crisp instead of greasy.
- Mix the topping until it forms small clumps; do not overmix into a dough or it will bake dense.
- Spread the topping all the way to the edges so the apples do not dry out around the sides.
- Bake until the topping turns golden brown and the filling bubbles around the edges; underbaked crisp tastes floury and bland.
- Let the apple crisp rest at least 15 minutes before serving so the juices thicken and the topping sets.
- Do not cover the crisp while it bakes, or the topping will steam and lose its crunch.
- If the top browns too quickly, tent loosely with foil near the end of baking, but keep a little vent so steam can escape.
How to Make Apple Crisp Recipe With Oats
Step 1: Prep the oven and pan
Preheat your oven to 350°F (175°C). Grease a 9×9 inch baking dish lightly with butter or nonstick spray. Set the pan aside while you prepare the filling and topping.
Step 2: Prep and slice the apples
Peel the apples if you prefer a softer texture. Core them and slice them into thin slices, about 1/4 inch thick. Try to keep the slices similar in size so they cook evenly.
Step 3: Mix the apple filling
Place the sliced apples in a large mixing bowl. Add granulated sugar, brown sugar, flour, cinnamon, nutmeg, cloves, salt, vanilla, and lemon juice. Toss everything until the apples look evenly coated and no dry patches of flour remain.
Pour the apple mixture into the prepared baking dish and spread it into an even layer. Scrape any juices and spices from the bowl over the top so you keep all the flavor. Set the dish aside while you make the oat topping.
Step 4: Make the oat crisp topping
In a medium bowl, combine rolled oats, flour, brown sugar, granulated sugar, cinnamon, and salt. Stir until everything mixes evenly and no big clumps of sugar remain. Add the cold butter cubes to the bowl.
Use a pastry cutter or a fork to cut the butter into the dry ingredients. Work the mixture until it forms pea-sized crumbs and some slightly larger clumps. If you use nuts, stir them in once the crumbs form.
Step 5: Top the apples
Sprinkle the oat topping evenly over the apples in the baking dish. Cover the apples completely, right up to the edges, so the topping protects the fruit and bakes into a crunchy layer. Gently press the topping down just a little so it sticks to the apples but still looks craggy and crumbly.
Step 6: Bake
Place the baking dish on the middle rack of the oven. Bake for 40 to 50 minutes, until the topping turns golden brown and the apple filling bubbles around the edges. If your oven runs hot, start checking at 35 minutes.
If the top browns too quickly while the apples still need time, tent a piece of foil loosely over the dish. Keep a small gap so the steam can escape and the topping stays crisp. The apples should feel very tender when you poke them with a fork.
Step 7: Rest and serve
Remove the apple crisp recipe with oats from the oven and place it on a cooling rack or trivet. Let it rest for at least 15 to 20 minutes so the juices thicken and the topping firms up. Serve warm or at room temperature with your favorite toppings.
Variations I've Tried
-
Caramel apple crisp: Drizzle 2 to 3 tablespoons of jarred caramel sauce over the apples before you add the topping. The caramel melts into the filling and gives a richer flavor. Reduce the sugar in the filling slightly if your caramel tastes very sweet.
-
Apple crisp with nuts: Add 1/2 cup chopped pecans or walnuts to the oat topping. The nuts toast in the oven and add crunch and a buttery flavor. This version tastes great with vanilla ice cream.
-
Apple cranberry crisp: Stir 1/2 to 3/4 cup dried cranberries into the apple filling. The tart cranberries balance the sweetness and add color. You can also use fresh or frozen cranberries and add an extra tablespoon of sugar.
-
Gluten free apple crisp: Use certified gluten free oats and swap the all-purpose flour with a gluten free all-purpose blend. The texture stays very similar, especially if you keep the oats old-fashioned style. Check all labels if you bake for someone with allergies.
-
Lower sugar version: Cut the sugar in both the filling and topping by about one third. The apples and oats still taste great, especially if you use naturally sweet apples like Honeycrisp or Fuji. A drizzle of maple syrup on top after baking can add sweetness without extra sugar in the mix.
How to Serve Apple Crisp Recipe With Oats
Serve this apple crisp recipe with oats warm in a bowl with a scoop of vanilla ice cream or a spoonful of whipped cream. You can also add a drizzle of warm caramel sauce or a spoonful of plain yogurt if you want something a bit lighter. It tastes great as a dessert after dinner or as a cozy weekend brunch treat with hot coffee, tea, or hot chocolate. If you have leftovers, enjoy a small bowl cold from the fridge as a not-too-sweet breakfast with a splash of milk.
How to store
- Room temperature: Keep the apple crisp loosely covered at room temperature for up to 1 day if your kitchen stays cool.
- Fridge: Store leftovers in an airtight container in the refrigerator for 3 to 4 days.
- Freezer: Wrap the baked and cooled crisp tightly and freeze for up to 2 months; thaw overnight in the fridge before reheating.
- Reheat in oven: Reheat in a 350°F (175°C) oven for 10 to 15 minutes until warm and crisp on top; this method keeps the topping crunchy.
- Reheat in microwave: Warm individual portions in the microwave for 30 to 45 seconds; the topping softens a bit, but the taste still hits the spot.

Ingredients
Instructions
- Preheat the oven to 350°F (175°C). Lightly grease a 9x9-inch (or 8x8-inch) baking dish with butter or nonstick spray.
- Prepare the apples by peeling if desired, then coring and slicing them into 1/4-inch thick slices, keeping the pieces as even as possible.
- In a large mixing bowl, combine the sliced apples, granulated sugar, brown sugar, flour, cinnamon, nutmeg, cloves, salt, vanilla, and lemon juice. Toss well until all the apple slices are evenly coated and no dry flour remains. If using dried fruit or maple syrup, add and mix in now.
- Transfer the apple mixture to the prepared baking dish, spreading it into an even layer and scraping in any juices and spices from the bowl.
- In a medium bowl, stir together the rolled oats, flour, brown sugar, granulated sugar, cinnamon, and salt until evenly combined and no large sugar clumps remain.
- Add the cold butter cubes to the oat mixture. Using a pastry cutter or a fork, cut the butter into the dry ingredients until the mixture forms pea-sized crumbs with some slightly larger clumps. If using chopped nuts, gently stir them in at this stage.
- Sprinkle the oat topping evenly over the apples, covering them completely to the edges of the dish. Gently press the topping down just a bit so it adheres while staying crumbly and textured on top.
- Bake on the middle oven rack for 40 to 50 minutes, or until the topping is golden brown and the apple filling is bubbling around the edges. If the topping browns too quickly, tent the dish loosely with foil, leaving a small vent so steam can escape.
- Remove the apple crisp from the oven and place it on a cooling rack or trivet. Let it rest for 15 to 20 minutes so the juices thicken and the topping firms up before serving.
- Serve warm or at room temperature, plain or with vanilla ice cream, whipped cream, yogurt, or a drizzle of caramel sauce as desired.
