Ingredients List (Apple Crisp Foundations)

  • Crumble Topping:
    • 1 cup (84 g) old‑fashioned rolled oats
    • ½ cup (70 g) all‑purpose flour
    • ½ cup (100 g) dark brown sugar
    • ½ tsp cinnamon
    • ¼ tsp salt
    • ½ cup (112 g) cold unsalted butter, cubed
  • Apple Filling:
    • ⅔ cup (133 g) granulated sugar (reduce to ½ cup if apples are extra sweet)
    • 3 Tbsp (24 g) arrowroot starch (or cornstarch)
    • 1 tsp ground cinnamon
    • ¼ tsp salt
    • 7 cups (840 g) peeled, diced apples
    • ½ tsp pure almond extract (sub vanilla, amaretto, bourbon, or dark rum if you like)

Step‑by‑Step Directions (Warm, Trusty Guidance)

  1. Preheat your oven to 350 °F. Place a foil‑lined rimmed baking sheet inside while it heats , this catches any filling spills when baking in your 10‑inch cast iron skillet (seasoned or homemade‑safe alternative).
  2. For the crumble topping: mix oats, flour, brown sugar, cinnamon, and salt in a bowl; cut in cold butter until large crumbs form. Chill in the freezer while you prepare the filling , this helps create a beautiful, crisp‑crunch texture.
  3. Apple filling: whisk sugar, starch, cinnamon, and salt in a bowl. Add the diced apples and almond extract, then gently toss to coat , all done in a minute or two.
  4. Spoon the apple mixture into your prepared skillet or baking dish. Scatter the chilled crumble topping evenly over the apples.
  5. Bake on that preheated rimmed sheet for 55–60 minutes , look for a golden topping and bubbling juices peeking through. Let it rest on a rack for at least 30 minutes (1 hour is ideal) before serving to avoid a lava‑hot filling.
  6. Store leftovers tightly covered or in an airtight container in the fridge, up to 2 days. Reheat in a warm oven (350 °F) for 15–20 minutes to renew that fresh crunch.

Family‑Tested Pro Tips

  • Crispier Crunch: Chilling the crumble topping before baking gives it beautiful separation and texture.
  • Skillet Swap Hack: If cast iron isn’t handy (or could rust), a 9–10″ ceramic baking dish is just as reliable and oven‑safe.
  • Sweetness Control: Know your apples , if they’re extra‑flavorful, dialing granulated sugar back to ½ cup keeps things balanced and not overly sweet.

Flavor Boost Ideas (Fun Experiments)

  • Nutty Addition: Toss in ½ cup chopped walnuts or pecans into the crumble before baking for extra crunch.
  • Gluten‑free Swap: Use certified gluten‑free oats and flour to make everyone happy and safe.

Refrigerator Rescue & Batch‑Friendly Tips

  • Topping? Make it 1–2 days ahead, tightly covered.
  • Filling? Whip it up a day early and keep refrigerated before assembling.
  • Whole assembly? Use a ceramic dish, stash the whole thing in the fridge, then bake right before serving , no rust worries, just warm deliciousness.

Mini Mistakes (and What I Learned)

When I first tried this recipe, I piled on the topping and ended up with doughy, underbaked oats. A quick freeze of the topping before baking fixed that immediately , crisp every time!
Also, I once skipped the foil on my baking sheet and ended up with a smoky oven , lesson: the foil catches spillover and makes cleanup a dream.


Bake with joy, share the smiles, and be sure to let me know , does this become your “best apple crisp ever,” too?
