Start by washing your fresh blueberries, raspberries, and blackberries. Once cleaned, toss them in a bowl with the lemon juice and sugar. This will help enhance their natural sweetness while adding a slight tartness from the lemon.
Preheat your oven to 350 degrees Fahrenheit. This is an important step as it ensures your Homemade Berry Crisp Recipe bakes evenly and comes out perfectly golden brown.
Take a 13”x9” casserole dish or a suitable baking pan and evenly spread the berry mixture into the bottom. Make sure to distribute them well for even cooking.
For the streusel, in a large bowl, combine the rolled oats, flour, brown sugar, and butter. Use a pastry knife or your fingers to cut in the butter until the mixture resembles coarse crumbs.
Once your streusel is ready, sprinkle it generously over the berry mixture, covering it completely. Make sure there are no gaps, as the streusel is the best part!
Place the dish in the preheated oven and bake for 40 to 45 minutes. You want the top to turn a beautiful golden brown and to be firm to the touch.
After baking, remove your berry crisp from the oven and let it cool for a few minutes before serving. This will help the juices set a little while still keeping everything warm.
Serve your Homemade Berry Crisp Recipe warm, topped with a scoop of vanilla ice cream or a drizzle of caramel for an extra treat. Enjoy the warm, gooey berry goodness!
