Easy Frozen Peach Crisp: A Cozy Dessert Made Simple

When you crave a warm, homemade dessert but don’t have fresh summer peaches available, an Easy Frozen Peach Crisp is the perfect solution. This comforting dessert transforms simple frozen peaches into a sweet, juicy filling covered with a golden, buttery oat topping. It delivers all the flavors of a classic peach crisp while saving time and effort, making it ideal for busy weeknights, family gatherings, or a relaxing weekend treat.

Unlike traditional fruit desserts that depend on seasonal produce, frozen peaches allow you to enjoy this recipe all year long. The peaches maintain their natural sweetness and soft texture, while the crisp topping adds a satisfying contrast with its crunchy oats, cinnamon warmth, and rich buttery flavor.

Why Frozen Peaches Work Perfectly for Crisp

Frozen peaches are a convenient ingredient because they are usually picked and frozen when they are ripe, helping preserve their flavor. They also eliminate the need for peeling and slicing fresh fruit, which makes preparation much faster.

The secret to a great frozen peach crisp is balancing the moisture from the peaches with a topping that becomes beautifully crisp during baking. A small amount of flour or cornstarch helps thicken the fruit juices, creating a delicious syrup-like filling instead of a watery dessert.

Ingredients You Will Need

For the Peach Filling:

6 cups frozen sliced peaches
½ cup granulated sugar (adjust depending on sweetness of peaches)
2 tablespoons cornstarch or all-purpose flour
1 tablespoon lemon juice
1 teaspoon vanilla extract
1 teaspoon ground cinnamon
A small pinch of salt

For the Crisp Topping:

1 cup old-fashioned rolled oats
¾ cup all-purpose flour
½ cup brown sugar
½ teaspoon cinnamon
½ cup unsalted butter, cold and cut into small pieces
A pinch of salt

Step-by-Step Method

Step 1: Prepare the Oven and Baking Dish

Begin by preheating your oven to 375°F (190°C). Lightly grease a medium-sized baking dish, such as an 8×8-inch or similar casserole dish, with butter or cooking spray.

Preparing the dish first ensures that the crisp will bake evenly and prevents the fruit filling from sticking to the bottom.

Step 2: Make the Peach Filling

Place the frozen peaches directly into a large mixing bowl. There is no need to fully thaw them beforehand.

Add the sugar, cornstarch, lemon juice, vanilla extract, cinnamon, and salt. Gently stir everything together until the peaches are evenly coated.

The cornstarch will mix with the natural juices released from the peaches during baking, creating a thick and glossy sauce that surrounds each slice of fruit.
