Ingredients

With some berries and simple pantry ingredients, you can make your recipe for fresh blueberry crisp with 10 minutes of prep work.

FOR THE JUICY FILLING

Fresh Blueberries – or frozen
Sugar – granulated white sugar
Flour – all-purpose flour
Ground Cinnamon – for a hint of flavor
Fresh Lemon – both the zest and lemon juice

FOR THE CRUMBLY TOPPING

Butter – we use salted since that’s what we usually have on hand
Brown Sugar – light or dark brown sugar
Flour – all-purpose (see notes for substitutions)
Oats – we prefer the taste and texture of old fashioned oatmeal
Pecans – or your favorite chopped nuts
Ground Cinnamon
Ground Nutmeg

How to Make – Step by Step Instructions

To start, place your oven rack in the center position and preheat your oven to 375 degrees F.

Step 1 – Prep Lemon

Zest the whole lemon, then cut it in half and squeeze the juice from one half.

Tip – we like to use a Microplane to zest like a pro!

Step 2 – Mix Filling

In a medium bowl, toss blueberries (washed & dried), granulated sugar, lemon zest, lemon juice (approximately 1 tablespoon), and 3 tablespoons of flour together.

Then, place the blueberry mixture in a 2-quart baking dish.

Step 3 – Mix Topping

Next, give the same bowl you mixed your blueberries a quick wipe, and then combine the butter, brown sugar, old-fashioned oats, flour, nuts, cinnamon, and nutmeg with a fork.

Tip – Reusing the same bowl, makes this a one bowl, one pan recipe!!

Spread the topping over blueberry filling.

Step 4 – Bake

Place in the oven with a cookie sheet underneath and bake for 35-40 minutes or until the top is golden brown and the fruit is bubbly. Cool slightly and serve warm or at room temperature.

Tips & Tricks

You can use any 2-quart baking dish to make your blueberry crisp. We like to use our 9-inch pie pan or a 9×9 baking dish.
If you’re not a fan of pecans, you can leave them out or swap them for your favorite nut, like walnuts or almonds.
To prevent an oven cleanup nightmare, place a cookie sheet under your fruit crisp while it’s baking. Baked-on fruit is HARD to clean!
You can mix and match the fruit combinations in the recipe. Try blueberry peach, blueberry apple, or strawberry rhubarb.
In our opinion, vanilla ice cream is a must for serving!

Topping Ideas

Vanilla or cookie dough ice cream
Maple syrup
Whipped cream

How to Store a Blueberry Crisp

Refrigerator – Store any leftover crisp in the refrigerator in an airtight container. If desired, reheat slightly on high power in the microwave.

Freeze Before Baking – Prepare the recipe as directed and cover it tightly with plastic wrap and then foil. Freeze for up to one month. To bake the blueberry crisp from frozen, preheat your oven to 375 degrees F and bake for about 50-60 minutes or until hot and bubbly.

Freeze After Baking – Freeze your crisp in an airtight container for up to 3 months. Don’t forget to label and date it.

Make-Ahead – Make the recipe for blueberry crisp with oats ahead and then refrigerate until ready to bake. Follow the baking instructions when ready to serve. You can also make a batch of topping and freeze it for later. When you have fresh fruit, prep it and add your frozen crumbly oat topping and bake as instructed.

FAQs

What type of baking dish should I use?

We like to use a deep-dish 9-inch pie plate to make a fruit crisp, but any 2-quart oven-safe baking dish would be great.

How do I make a dairy-free & gluten-free blueberry crisp?

We suggest using gluten-free rolled oats in the topping instead of regular oats. Also, instead of all-purpose flour or whole wheat flour, use almond flour in the topping and use corn starch in the fruit filling. Omit the butter and use coconut oil in the topping mixture to make it dairy-free.

Can I use Frozen Blueberries?

Yes, you can use frozen blueberries to make a blueberry crisp recipe the same as you would fresh berries. However, you may want to increase the amount of flour (or cornstarch) in the berry filling by 1 tablespoon due to the higher moisture content. You also want to increase the cooking time to approximately 45 minutes.
