We do it every season.
My husband and I both get so excited about the arrival of blueberries 
that we buy and buy and buy until our refrigerator over-floweth. We went away for a few days so in my last minute clean out of the fridge I threw a few pints of surplus berries in the freezer. This morning while trying to retrieve some frozen chicken breasts those frozen blueberry pints just kept getting in the way. I knew I had to make use of them.
As much as I love to bake. I have to admit I have never made a blueberry pie. It is one of my husband's favorites but I find that the homemade versions I have tried are often wet and the crust is soggy and leaden. I also honestly didn't feel like dragging out the food processor to make pie crust. So I decided to make a Blueberry Crisp. I have a fool-proof crisp that I use on apples and I knew it would transfer well. I decided to use cornstarch and heat the blueberries on the stove to help bring out and thicken the juices. I was pleasantly surprised by the results. The berries thickened up beautifully and the crisp added that crunch that made it a perfect summer dessert.
Blueberry Crisp
Preheat oven to 350 degrees
Approximately 4 cups of frozen blueberries (3 pints)
1/2 cup sugar
3 tablespoons cornstarch
1 teaspoon lemon juice
1 cup old-fashioned oatmeal
1/3 cup flour
1/2 cup brown sugar
1/4 teaspoon salt
1/3 butter
Put blueberries, sugar and cornstarch in medium saucepan over medium heat. Stir until they start to bubble slightly and let them simmer for 4-5 minutes until it thickens up. The sauce will cling to a wooden spoon. Take off the heat and mix in the lemon juice. Pour the blueberry mix into a casserole dish.
In another bowl, mix then oatmeal, flour, brown sugar and salt. Blend in the cold butter with fingers or a pastry blender until the whole thing is combined to a crumbly mix. Sprinkle over blueberry mixture.
Bake for 30 minutes until topping starts to brown. Serve warm with vanilla ice cream.
That crisp mix is great on an apples, just add 1/2 teaspoon cinnamon. I will definitely do this again with peaches when they come in, and add a bit of almond extract.
Enjoy!
My kids love bacon, raisins and broccoli so this one was a slam dunk. Its fast and easy and it is a huge hit at barbecues and potlucks.
