This is a variation of our frozen fruit crisp base recipe. Although peaches are traditionally a summer ingredient, this easy peach crisp can be made year-round. Frozen peaches are available in most grocery stores, plus, using frozen peaches instead of fresh makes prep time that much quicker for you! Frozen peach crisp also happens to be a naturally healthier (but just as delicious) alternative to peach pie or cobbler. Give it a try and let us know how it turns out for you!

Use ~1 teaspoon of lemon zest in place of or in addition to the lemon juice to enhance the lemon flavor.
Ingredient Substitutions
- Frozen Peaches: substitute some of the peaches with any other variety of fresh or frozen fruit. Blueberries, strawberries, raspberries, dark cherries, blackberries, apples, pears, or a combination of a few would all be delicious! Blueberry peach crisp is one of our favorites!
- Brown Sugar: substitute coconut sugar, turbinado sugar, or cane sugar, but note that the flavor won’t be as complex if using cane sugar. Honey or agave can also work, but if using, drizzle it over the peaches after coating the fruit in cornstarch.
- Crystallized Ginger: substitute ½ teaspoon freshly grated ginger or ¼ teaspoon dried ginger. Note that crystallized ginger can greatly vary in size. If yours includes very small pieces, consider cutting back on the amount.
- Cornstarch: substitute ¼ cup all purpose flour.
- Lemon Juice: substitute orange juice. You can also add or substitute 1 teaspoon lemon zest.
- Old Fashioned Oats: you can substitute quick oats, but note the quality of the crisp is not as good. Do not substitute steel cut oats.
- All Purpose Flour: substitute white whole wheat flour, whole wheat pastry flour, or spelt flour for added nutrition, but note that the crust will be slightly denser.
- Almonds: substitute chopped pecans or walnuts.
- Butter: to make a vegan peach crisp, you can try substituting avocado or canola oil, but we weren’t impressed with the results. We did not test coconut oil, but it would probably work better than other oils.

Recipe Variations
To make a gluten-free peach crisp, substitute a gluten-free flour mix, such as King Arthur’s Measure for Measure Flour, in place of the all-purpose flour, and be sure to use certified gluten-free oats.
For a boost of warming flavor in your peach crumble with oats, add a teaspoon of vanilla to the crisp mixture.

Is this a Healthy Peach Crisp?
Although this is a dessert recipe, we still found a few ways to ensure you get some good nutrition in every bite. Peaches, old-fashioned oats, almonds, and less sugar than most desserts makes this a perfect recipe for those looking for a lighter dessert!
Frozen Peaches
Fruit is packed with vitamins, minerals, fiber, and antioxidants. Together, these nutrients promote heart health and may reduce inflammation. Peaches also contain natural sugars which decrease the need for added sugar.
Oats
Oats of any variety are a good source of fiber and complex carbohydrates. Fiber is important for digestion, satiety, stable blood sugar, good cholesterol, and healthy gut bacteria. Complex carbohydrates are important for steady energy and focus.
Almonds
Almonds are a great source of plant-based protein and healthy fat, especially heart-healthy monounsaturated fats.
Less Sugar than Most Desserts
Although we expect to find sugar in most desserts, many recipes and pre-made desserts contain way more than necessary. In this frozen peach crisp, we use cinnamon and lemon juice to enhance the natural sweetness of the fruit and nuts, then add some brown sugar to balance the flavors out. Each serving of frozen fruit crisp contains ~14 grams (~1 Tablespoon) of added sugar – far less than you would find in any store bought dessert! Even homemade fruit crisp recipes have almost twice the amount of sugar than is in this recipe!
Peach Crisp Serving Suggestions
Serve frozen peach crisp straight from the oven with a small scoop of vanilla ice cream, banana nice cream, or a dollop of homemade whipped cream,
You can also make this recipe a day or two in advance. Allow to cool completely, then cover and place in the refrigerator until ready to eat. To reheat, preheat the oven to 350ºF and cook for 20 minutes, or until peaches are bubbling and the mixture is heated through.
You can also serve fruit crisp chilled on its own or topped with whipped cream. Good luck keeping sneaky hands from sampling a taste if you leave it in the fridge for too long before serving!
Storage Recommendations for Frozen Peach Crisp
Cool completely, cover, and place in the refrigerator. The fruit crisp will keep its quality in the refrigerator for up to 3-5 days (but we doubt it will last that long!). The crunchy peach crisp topping may begin to get soggy, but we promise it will still taste good!
