Topping Ideas
This crisp is delicious as written, but you can elevate it with a few finishing touches:
- Vanilla ice cream
- Bourbon or rum caramel sauce
- Lightly sweetened whipped cream
Recipe Tips
- Use ripe, in-season peaches. Choose fruit that smells fragrant and yields slightly when pressed near the stem.
- Don’t skip the cornstarch. It thickens the juices released during baking and gives the filling a glossy, syrupy texture.
- Keep spices light. Only a small amount of cinnamon and nutmeg lets the peach flavor shine.
- Choose rolled oats, not instant. Old-fashioned oats give the topping a pleasant chew and crunch; instant oats can turn powdery when processed.
Recipe FAQs
Here are answers to common questions about making peach crisp with an oat topping. If you have other questions, leave a comment on the recipe and the author will reply.
What’s the easiest way to peel peaches?
Blanching is the simplest method. Briefly boil the peaches, plunge them into an ice bath, and the skins slip off easily. This is faster and cleaner than peeling with a knife for large batches.
Can I use frozen peaches?
Yes. Use thawed frozen peaches and mix them with the sugar and cornstarch before transferring to the baking dish. The method is the same as with fresh peaches.
What about canned peaches?
Canned peaches are not recommended. They are already soft and sweet, which can result in a mushy filling rather than a crisp texture.
Can I use different fruits?
Absolutely. Nectarines work well, and you can combine peaches with other fruit up to about 3.5 pounds total. Popular combinations include:
- Peach and blueberry
- Peach and rhubarb
- Peach and apple
- Peach and blackberry
- Peach and raspberry
- Peach and cherry
Can this recipe be doubled?
Yes—double the ingredients and bake in a 9×13-inch pan or two 9-inch dishes, adjusting baking time as needed until the filling bubbles and the topping browns.
Can this be made in advance?
Yes. Prepare the oat topping and refrigerate in a sealed bag for 2–3 days or freeze for up to a month. Assemble the peach filling and store it in the fridge up to one day before baking.
Storage Instructions
Allow the crisp to cool, then cover tightly and refrigerate. Leftovers keep up to 5 days in the refrigerator or about 3 days at room temperature. You can also freeze the baked crisp for up to three months; thaw in the refrigerator overnight and reheat before serving.
