Old-Fashioned Frozen Peach Crisp

Step 4: Assemble the Peach Crisp

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish or a similar-sized casserole dish.

Pour the prepared peach mixture into the dish and spread it evenly. Sprinkle the oat topping over the peaches, making sure the entire surface is covered.

Avoid pressing the topping down too firmly. Keeping it loose allows the heat to circulate and creates a lighter, crispier texture.

Step 5: Bake Until Golden and Bubbly

Place the dish in the preheated oven and bake for 40–50 minutes.

The peach filling should be bubbling around the edges, and the topping should become golden brown and crunchy. The baking time may vary slightly depending on how frozen the peaches were when placed in the oven.

If the topping begins browning too quickly, loosely cover the dish with aluminum foil during the final part of baking.

Step 6: Let It Rest Before Serving

Once baked, remove the peach crisp from the oven and allow it to cool for at least 15–20 minutes.

This resting period allows the fruit filling to thicken and makes serving easier. While it may be tempting to eat it immediately, waiting a few minutes helps the flavors develop and gives the dessert its perfect texture.

Serving Suggestions

Old-fashioned frozen peach crisp is delicious served warm on its own, but it becomes even more special with a few simple additions:

• A scoop of vanilla ice cream for a classic combination
• A spoonful of whipped cream for extra creaminess
• A drizzle of caramel sauce for a richer dessert
• A sprinkle of cinnamon before serving for added warmth

The contrast between the warm peaches and cool ice cream creates one of the most beloved dessert experiences.

Tips for the Best Peach Crisp

Use quality frozen peaches: Since peaches are the star ingredient, choosing sweet, flavorful frozen fruit makes a big difference.

Do not skip the lemon juice: A small amount of acidity balances the sweetness and enhances the natural peach flavor.

Keep the butter cold: Cold butter creates a crispier topping because it melts slowly during baking, forming delicious golden clusters.

Adjust sweetness based on peaches: Some frozen peaches are naturally sweeter than others. Taste the filling mixture before baking and adjust the sugar if needed.

Make it ahead: Peach crisp can be assembled in advance and stored in the refrigerator before baking. Simply add a few extra minutes to the baking time if it goes into the oven cold.

Storing and Reheating

Leftover peach crisp can be stored in an airtight container in the refrigerator for up to four days. To reheat, warm individual portions in the microwave or place the baking dish in the oven until heated through.

The topping may soften slightly after refrigeration, but reheating it in the oven can help restore some of its original crisp texture.
