What’s in Blueberry Crisp?
A ‘crisp’ is a fruit dessert baked with a crunchy topping, unlike a ‘cobbler’ which has a dough topping, or a ‘crumble’ that has a streusel topping without oats. A crisp is the easiest of the three to make.
Fresh from the farmer’s market, supermarket, or frozen, blueberries have a sweet, mildly floral flavor that pops in your mouth. Choose berries that are whole and unblemished.
A simple topping is made with butter, oatmeal, brown sugar, flour, seasonings, and optional nuts for extra crunch.
PRO TIP: Double up the topping recipe and save half in the freezer as a topping for ice cream, cheesecake, oatmeal, or future fruit crisps!
FRUIT: Blueberries make for a colorful and striking crisp, but so do other berries like blackberries, raspberries, strawberries. Apples (add some diced cheddar cheese), peaches, and even rhubarb (add extra sugar) are also great for crisps. Or mix and match a variety of summer fruits and berries like raspberry rhubarb!
THE TOPPING: Make a gluten-free topping using almond or coconut flour, a sugar-free version by switching out a 1:1 ratio sugar substitute like erythritol (aka Swerve) or monk fruit (aka Lakanta). Adding nuts or even unsweetened flaked coconut will give the dessert added crunch and flavor! Vegan? No problem! Switch out the butter for refined coconut oil.
PRO TIP: Cook nuts or coconut in a dry sauté pan until barely fragrant. This cooks off some of the oil and makes them extra crunchy, plus intensifies their flavor in all recipes.
How to Make Blueberry Crisp
Serve this sweet dessert with a scoop of vanilla ice cream!
- Mix berries, flour, sugar, lemon juice, and zest in a baking dish.
- Blend the topping ingredients. Stir in optional nuts or coconut.
- Spoon topping over blueberry mixture. (As per recipe below)
- Bake blueberry crisp on top of a baking sheet until bubbling and golden.
Blueberry Crisp Baking Tips
If the filling is not fully cooked but the topping is browned, cover with aluminum foil and bake in intervals of 5 minutes until cooked through.
For best results, prep blueberry crisp no more than a day before. Cover it with plastic wrap and store it in the refrigerator until it’s ready to bake.
A baked crisp can be frozen up to 3 months, and be sure to label the date on the outside. Allow it to thaw in the refrigerator before baking.
Alternately, freeze an unbaked crisp with the fruit separate from the topping. Thaw separately, sprinkle the topping over the fruit and bake. So easy!
