Summer Berry Crisp Recipe

Last week I got invited to an event put on by the Washington State Beef Commission to assist the fabulous Misty Banchero (aka Seattle Butcher's Wife) and make some side dishes for a group of lovely ladies who wanted to learn more about grilling. You can read all about my adventures here.

Most of the recipes I made and served already live right on the site, but this one. This one is new, and it was definitely my favorite.

(Curious about what else I made? Check out my Perfect Grilled Asparagus, Caesar Vinaigrette Dressing, and these Garlic Gruyere Potatoes!)

This dessert is perfect for cookouts, potlucks, family dinners, or anyone who loves a warm fruit dessert with a crunchy oat topping.

It uses blackberries, raspberries, blueberries, and strawberries, so every scoop gives you a mix of sweet, tart, and juicy berries.

The filling is cooked first to thicken the berries before baking, so the crisp doesn't turn watery. This recipe makes 16 generous servings in a high-sided 10x13-inch pan and doesn't need pie dough, frosting, decorating, or careful slicing.

Adding apple cores and peels, along with lemon peel, pulp, and seeds tied in cheesecloth, is a smart way to add natural pectin. This helps the berry syrup thicken without changing the crisp's flavor.

Why You'll Love This Dish

  • Feeds A Crowd: This recipe makes 16 servings, which makes it perfect for parties, barbecues, and big family meals.

Recipe Shopping List

Wondering if you have to hit the store? Here's the list of items you'll need to make this recipe. For specific amounts, please refer to the printable recipe card at the bottom of the post.

  • Mixed Berries - Blackberries, raspberries, blueberries, and strawberries create a sweet-tart filling with different textures in each bite. Fresh berries are great in season, and frozen berries work well when drained lightly or cooked a bit longer.
  • Granulated Sugar - Sweetens the berries and helps draw out their juices. It balances tart raspberries and blackberries without covering up the fruit flavor.
  • Cornstarch - Thickens the berry juices into a glossy filling. Mixing it with the sugar first helps prevent clumps.
  • Fresh Lemon Juice - Adds brightness and keeps the berry flavor from tasting flat. Bottled lemon juice works in a pinch, but fresh tastes cleaner.
  • Apple Cores And Peels - Used in cheesecloth to add natural pectin to the cooked berries. This helps the filling set without adding apple chunks.
  • Lemon Peel, Pulp, And Seeds - Tied with the apple scraps to support thickening and add light citrus flavor during cooking.
  • Oatmeal - Gives the topping its hearty texture. Old-fashioned oats are best for a chewy, crisp finish.
  • All-Purpose Flour - Helps bind the topping so it bakes into crumbly clusters instead of loose oats.
  • Cold Butter - Creates rich flavor and crumbly texture. Keep it cold and cut it into chunks so the topping bakes up with crisp edges.
  • Brown Sugar - Sweetens the crumble topping and adds a light caramel note. Light or dark brown sugar both work.

How To Make This Recipe

This is just the overview so you can see what you're actually getting into here. When you are cooking, you'll want to use the full recipe at the bottom of the page.

  1. Prep The Pan And Oven - Preheat the oven or pellet grill to 350°F. Spray a 10x13-inch high-sided baking pan well with baking spray.
  2. Start The Berry Filling - Mix the sugar and cornstarch together, then toss half the berries with that mixture. Tie the apple scraps and lemon scraps in cheesecloth and add them to the pot.
  3. Cook Until Thickened - Heat the berry mixture over low to medium-low heat, stirring gently and often, until the berries are bubbling lightly and the juices have thickened into a syrupy sauce.
  4. Make The Crumble Topping - Mix the oats, flour, cold butter chunks, and brown sugar until the butter is in pea-sized pieces and the mixture looks crumbly.
  5. Assemble And Bake - Cool the cooked berries for 10 to 15 minutes, remove the cheesecloth packet, then stir in the reserved fresh berries and lemon juice. Pour into the pan, add the oat topping, and bake for about 1 hour, until bubbly, thickened, and lightly browned.

Recipe FAQ

Can I Use Frozen Berries For Summer Berry Crisp?

Yes, frozen berries work well. They tend to release more liquid than fresh berries, so the filling may take longer to cook down on the stovetop and the crisp may need extra baking time. Watch for bubbling fruit and a browned topping.

Can I Make This Berry Crisp Ahead Of Time?

Yes. You can cook the berry filling a day ahead and keep it covered in the refrigerator. Add the fresh berries, lemon juice, and crumble topping right before baking for the best texture.

How Do I Store Leftover Summer Berry Crisp?

Cover the cooled crisp and store it in the refrigerator for up to 4 days. The topping will soften as it sits, but the flavor stays rich and fruity.

How Do I Reheat Berry Crisp?

Reheat individual portions in the microwave until warm. For a crisper topping, place the pan or a portion in a 325°F oven until heated through.

Can I Change The Berry Mix?

Yes. Use any mix of blackberries, raspberries, blueberries, and strawberries. You can lean heavier on blueberries for a sweeter filling or add more raspberries for extra tart flavor.

Can I Make The Topping Without Oats?

Yes. Replace the oats with extra flour for a more streusel-style topping. The texture will be less chewy and more like a buttery crumb topping.

Why Are Apple And Lemon Scraps Used In The Filling?

Apple peels, cores, lemon peel, pulp, and seeds add natural pectin to the berry mixture. They help thicken the fruit filling during cooking, then get removed before baking.

Instructions

  1. Preheat your oven (or pellet grill) to 350. Liberally spray a 10x13" high-sided baking pan with baking spray.
  2. Combine the cornstarch and sugar, and stir until fully combined. Toss half the berries with the sugar and cornstarch mixture. Stir gently to evenly coat. Put the apple core, peels, and lemon peel, pulp, and seeds into cheesecloth and secure with baker's twine. Add to the berries.
  3. In a large pot on the stovetop, heat the berries and sugar over low to medium-low heat.
  4. Stir gently, but frequently, until the mixture is bubbling lightly and has thickened into a syrupy consistency. This took me about 40 minutes. Take care not to scorch the bottom!
  5. While the mixture is cooking, place the oatmeal, flour, butter, and brown sugar into a mixing bowl. Mix until the butter is in pea-sized chunks and the mixture is crumbly. This can also be done with your hands if you'd like.
  6. Once the berries are cooked, remove from the stove and let cool for 10-15 minutes.
  7. Gently mix together the reserved half of the berries with the cooked berries. Stir in the lemon juice.
  8. Crumble the oatmeal mixture evenly over the berries.
  9. Bake at 350°F for approximately one hour. Crisp is done when the berries are bubbly, the mixture has thickened, and the topping is lightly browned. Watch carefully! Baking times will vary depending on your oven and the degree of freezing of your berries.
  10. Remove from the oven, let rest for 10-15 minutes, and serve with vanilla ice cream or sweetened whipped cream.
