Apple Crisp With Oat Topping

Recipe by lounarecipes

From the Blog Author

This Apple Crisp With Oat Topping is one of my all‑time favorites because it brings back the cozy scent of my grandmother’s kitchen after a long fall day. I love how the apples soften into a warm, caramelized sauce while the oat topping turns golden and crunchy. What I love most is the harmony between the fruity, lightly spiced apples and the nutty, buttery oat mixture. A sprinkle of cinnamon, a dash of nutmeg, and a spoonful of brown sugar give the filling a sweet, almost caramel‑like depth that feels indulgent yet comforting. The oats—rolled, not instant—provide a satisfying bite that contrasts nicely with the tender fruit beneath. A little tip from my experience: dry the oats before mixing in the butter and sugar. Tossing them in a dry skillet and giving them a quick toast lifts their flavor and keeps the topping from becoming too soggy. Also, slice the apples thinly and slightly off‑center; thin slices bake evenly and let the spices soak in nicely. If you try this, I’d love to hear about it—send us an email and tell us what you think. I’m always excited to see how this simple, fast dessert brings joy to your table.

Frequently Asked Questions

What are the best apples to use for this Apple Crisp recipe?

For the best texture and flavor in this Apple Crisp, choose firm, slightly tart apples like Granny Smith or Honeycrisp. These varieties hold their shape well during the 45 minutes of baking time at 350°F (175°C). Avoid overly soft apples that might turn mushy.

Can I make this Apple Crisp topping gluten-free or vegan?

Yes, you can easily adapt this recipe! For a gluten-free version, substitute the 1/2 cup all-purpose flour with a 1:1 gluten-free baking blend. To make it vegan, replace any butter used in the topping with a solid vegan butter alternative.

How should I store leftover Apple Crisp with Oat Topping?

Store leftover Apple Crisp tightly covered at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For the best crisp topping texture, reheat individual servings in a toaster oven or a 350°F oven until warmed through.
