Whether I decide to make a smoothie, this dessert, or anything else with berries, that frozen bag is my go-to!

The best part? Frozen berries aren’t just good frozen. Thaw them out, and you have yourself the perfect berries for whatever dish you plan to make!

This easy mixed frozen berries recipe comes together in just 10 minutes and features the yummiest oat crumble topping. A quick & easy dessert the whole family will love!

How to Make This Recipe

Frozen fruit is best because it is frozen when it is at peak freshness. It has tons more flavor and nutrients. Plus, frozen organic fruit is much cheaper than fresh. Win win!

Since the berries are getting baked, it is perfect to use frozen berries. They’re going to get all soft and mushy anyway. Even better? You can cook it with the berries frozen! No need to thaw them. You can have this frozen berry crumble prepped and in the oven in less than 10 minutes. Love that!

Ingredient Notes

Flour & Sugar: The berry filling comes together quite easily. Because the berries will sweat a bit, I like to thicken them with some added flour, along with a little sugar for added sweetness.

Lemon Zest: Don’t miss this step! The lemon zest adds brightness to the berry mixture which is a must.

Frozen Berries: My favorite frozen berries to use are a combination of raspberries, blueberries, and blackberries. But you could use just 1 berry or any combination of other berries. For larger fruit/berries like strawberries, cherries, mango, etc I will pulse the frozen fruit in the food processor a few times so the chunks are more bite-size.

Fresh Berries: This same recipe also works for fresh fruit too! Just substitute the same amount of fresh berries for frozen. No other substitutions or changes in baking time are needed.

Oat Crumble Topping: The real star of this frozen berry crumble is the oat crumble topping. Crunchy and toasty rolled oats mixed with butter, flour, and sugar. It crisps up atop the berries and gives this dessert a perfect sweet oat crumble crunch. Literally, the best oat crumble topping I have ever had!

Recipe Step by Step

  1. In a mixing bowl, make the berry filling by combining all ingredients and tossing to combine. Set aside.
  2. In a separate mixing bowl, make the oat crumble by combining all ingredients, then use your fingers to pinch the butter and incorporate it with the dry ingredients. Keep pinching and tossing together with your hands until evenly combined. You will be left with many pea-sized pieces of butter mixed in with the oat mixture. Set aside.
  3. Pour the berry filling into a 1-1/2 quart baking dish (or 8×8 pyrex baking dish, a pie baking dish, or even a 12″ cast iron skillet). Top with the oat crumble topping and spread to an even layer.
  4. Bake uncovered until the berry filling is bubbling, and the oat crumble is golden brown, about 1 hour. Let cool for 1 hour before serving.
  5. Serve at room temperature. Delicious with ice cream or whipped cream.
