Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. In a large bowl, toss 5 peeled, cored, and 1/4-inch thick sliced Granny Smith apples with 1/3 cup granulated sugar, 1 1/2 tsp ground cinnamon, and 1 tbsp lemon juice until evenly coated.
  2. Step 2: Transfer the apple mixture to a 9-inch square baking dish, spreading it evenly.
  3. Step 3: In another bowl, combine 3/4 cup rolled oats, 1/2 cup all-purpose flour, 1/3 cup packed light brown sugar, and 1/4 tsp salt. Add 6 tbsp cold, cubed unsalted butter and use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs.
  4. Step 4: Sprinkle the oat crumble evenly over the apples in the baking dish.
  5. Step 5: Bake uncovered for 35-40 minutes, until the apples are tender and the topping is golden brown and crisp.
  6. Step 6: Remove from the oven and let cool for 10 minutes before serving warm, optionally with vanilla ice cream.

Frequently asked questions

How long does Oven-Roasted Cinnamon Apple Crumble take to make?

Total time is about 55 minutes (15 min prep + 40 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Oven-Roasted Cinnamon Apple Crumble?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep granulated sugar from drying out.

Can I substitute ingredients in Oven-Roasted Cinnamon Apple Crumble?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Oven-Roasted Cinnamon Apple Crumble for a different number of people?

The recipe is written for 6 servings. Multiply each ingredient by (your serving target / 6). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
