Ingredients You’ll Need
- 5 cups peaches, sliced: Fresh, ripe peaches are key for sweetness and flavor. If peaches aren’t in season, you can also use frozen ones—just thaw and drain excess liquid.
- 1/2 cup sugar: This sweetens the peach filling perfectly. You can use brown sugar for a deeper flavor or honey for a healthier alternative.
- 2 tbsp cornstarch: This helps thicken the peach juices, giving a nice sauce consistency. You can substitute with arrowroot if needed.
- 1/2 tsp vanilla: Pure vanilla extract enhances the flavor of the peaches. Avoid imitation vanilla for the best taste.
- 1 tbsp lemon juice: This brightens the flavors and balances the sweetness. Fresh lemon juice is preferred, but bottled will work in a pinch.
- 1/2 cup flour: All-purpose flour provides the base for the crisp topping. You can use whole wheat flour for a nutty flavor.
- 1/2 cup brown sugar: This adds a rich sweetness and slight chewiness to the topping. Substituting with coconut sugar gives a healthy alternative.
- 1 tsp cinnamon: This classic spice complements the peaches wonderfully and adds warmth to the dessert.
- 1/2 cup butter, cold & cubed: Using cold butter ensures a flaky topping. If you prefer a dairy-free option, coconut oil or vegan butter works beautifully.
- 3/4 cup old-fashioned rolled oats: These create that irresistible crisp texture. Quick oats can be used in a pinch but won’t provide the same chewiness.
How to Make Simple Peach Crisp Recipe with Oat Topping
- Preheat your oven: Set the oven to 350 degrees Fahrenheit. This ensures your crisp will bake evenly. While it heats, spray a pie pan with non-stick spray and set it aside.
- Prepare the peaches: Pit, peel, and slice enough peaches to equal 5 cups. Toss these freshly sliced peaches into a medium-sized bowl.
- Make the peach filling: Stir in 1/2 cup sugar, 2 tablespoons cornstarch, 1/2 teaspoon vanilla, and 1 tablespoon lemon juice until the peaches are evenly coated and the sugar starts to dissolve.
- Transfer to the baking dish: Pour the peach mixture into the prepared pie pan, making sure to spread it out evenly for consistent baking.
- Prepare the topping: In a food processor, pulse together 1/2 cup flour, 1/2 cup brown sugar, and 1 teaspoon cinnamon until well combined. Then, add in the cold, cubed butter and pulse until you achieve a crumbly texture.
- Add oats to the topping: Gently pulse in 3/4 cup old-fashioned rolled oats. The goal here is to maintain some chunks for that satisfying crunch.
- Top the peaches: Pour the oat mixture evenly over the prepared peaches, ensuring you cover them well.
- Bake: Place the pie pan in the oven and bake for 30-35 minutes. You’ll know it’s done when the topping turns golden brown and the peach juices are bubbling around the edges.
Storing & Reheating
To store your Simple Peach Crisp, let it cool to room temperature, then cover it tightly with plastic wrap or store it in an airtight container. It will keep at room temperature for up to 2 days. For longer storage, place it in the refrigerator, where it will last for about a week. You can also freeze it for up to 3 months—just make sure to wrap it well! When you’re ready to enjoy it again, simply reheat in the oven at 350 degrees Fahrenheit for about 15 minutes or until warmed through. Keep in mind that freezing may change the texture slightly, but it will still be delicious!
Chef’s Helpful Tips
- Be careful not to overmix the topping; you want those buttery chunks for the best texture.
- Use perfectly ripe peaches for the sweetest filling. If they’re slightly under ripe, you can increase the sugar a tad.
- If you’re short on time, you can prepare the filling and topping ahead. Just bake it when you’re ready to serve!
- To enhance flavors, consider adding a pinch of nutmeg along with the cinnamon.
- For a beautiful presentation, serve your peach crisp in individual ramekins.
You’ll fall in love with this dessert for its wonderful balance of flavors and textures, making every bite a joy. It’s comforting, it’s easy, and it’s absolutely homemade goodness you’ll want to savor.

Recipe FAQs

Absolutely! If fresh peaches aren’t in season, frozen peaches are a great substitute. Thaw them in the fridge beforehand and drain any excess liquid to prevent a soggy crisp.
How can I make this recipe gluten-free?
To make a gluten-free peach crisp, simply substitute the all-purpose flour with a gluten-free flour blend. Ensure that your oats are also certified gluten-free to avoid cross-contamination.

How do I know when my peach crisp is done baking?
Your crisp is ready when the topping is a lovely golden brown, and the peach juices are bubbling up around the edges. You can also check by inserting a toothpick into the topping—it should come out clean, indicating it’s nicely cooked through.
