Skillet Blueberry Crisp is made with fresh, juicy blueberries and finished with a crunchy almond oatmeal topping. Top it with a scoop of vanilla ice cream and it’s the perfect dessert, especially when blueberries are in season!
Have you ever tried baking in a cast iron skillet? I love that you take your recipes straight from the stovetop into the oven! You can make cakes, gooey skillet cookies, cornbread, cobblers, and more in this versatile kitchen pan.
While many people use the terms interchangeably, they are a little different! A crisp refers to a dessert with a fruit filling and a light streusel topping made from flour, sugar, oats, and butter.
A crumble is just a fruit crisp without the oats! The topping is usually a simple combination of butter, flour, and sugar with a more “clumpy” texture.
A cobbler, on the other hand, is a fruit dessert topped with a biscuit-like dough that either covers the entire dish or is dropped by spoonfuls across the top of the dessert.
While I love any of these fruit desserts, the oats make the perfect chewy texture for this delicious Blueberry Crisp!
WHOOPS! Forgot to include THE most important ingredient in the above pic – the BLUEBERRIES!
You’ll need the following ingredients for the fruit filling:
Fresh blueberries
Granulated sugar
Cornstarch
Ground cinnamon
Water
Here’s what you need to make the crunchy topping:
Old-fashioned oats
Sliced almonds
Light brown sugar
All-purpose flour
Ground cinnamon
Nutmeg
Kosher salt
Cold unsalted butter
Please review the recipe card carefully for the exact amounts needed!
First, preheat the oven to 350 degrees F. While the oven heats, we will make the blueberry filling.
Combine sugar, cornstarch, cinnamon, and water in a 10-inch cast iron pan or oven-proof skillet. Heat rapidly until thickened, stirring often. Then remove it from the heat and let it cool slightly.
Meanwhile, make the topping as directed below. We’ll add the blueberries to the sugar mixture once it cools.
First, mix together the oats, almonds, flour, brown sugar, cinnamon, nutmeg, and salt in a large bowl.
Cut the 6 tablespoons of butter into small pieces and use your clean hands or a pastry cutter to work the butter into the oat mixture until it is fully incorporated.
Now that the sugar mixture has cooled a bit, go ahead and add the blueberries, stirring completely to coat.
Spread the crisp topping in an even layer over the blueberries. Now place the skillet into the oven and bake for about 25 – 30 minutes.
Let the crisp cool slightly, then serve warm with fresh whipped cream or a scoop of ice cream if desired!
I use old-fashioned oats because I like the chewy texture they add, but you can use quick-cooking oats if you’re in a pinch or don’t have them on hand.
You can use frozen blueberries instead of fresh berries. No need to thaw them first, just add them to the sugar mixture as directed.
A splash of lemon juice or lemon zest really adds to the flavor of this blueberry dessert!
Use pecans or walnuts instead of almonds if desired.
You can omit the cinnamon and/or nutmeg from the topping and blueberry filling if you’re not a fan!
Transfer any leftovers to an airtight container. I like to keep them out at room temperature for the first day to retain the crunchiness, but after that, keep them in the refrigerator for up to 3 days.
Reheat in the microwave or at 350 degrees until warmed through.
You could make the filling and topping separately in advance, then assemble the crisp and bake it before you are ready to serve it! Otherwise, the topping would get soggy.
You can freeze blueberry crisp once you take it out of the skillet. Transfer the blueberry crisp to an airtight container and freeze for up to 3 months. Reheat in an oven-safe dish at 350 degrees until heated throughout.
