I enjoy a good fruit crisp. And I love blueberries. This simple blueberry crisp dessert is the best of both worlds. 

What Is A Fruit Crisp Dessert?

A fruit crisp is similar to a cobbler, but with a crumbly crispy topping of oats usually mixed with brown sugar and butter.

It bakes into a deliciously sweet thickened fruit filling topped with a crispy buttery oat crust.

What’s The Difference Between A Crisp & A Crumble?

Depending on who you ask, some may use the term crisp or crumble almost interchangeably.

I believe technically a crisp is the proper term when the dessert includes oats in the topping. But no matter what you call it – this blueberry crisp recipe is amazingly delicious.

What Ingredients Are In A Blueberry Crisp?

Filling:

• • Blueberries – obvs!
  • Granulated Sugar – adds sweetness & body
  • All-Purpose Flour – for thickening
  • Lemon Juice & Zest – to aid in thickening & add a touch of lemon flavor
  • Vanilla Extract – Gotta love a hint of vanilla!

Topping:

• • Oats – the body of the crispy topping
  • Softened Butter – encourages browning & crispiness
  • Brown Sugar – for sweetness with a molasses touch
  • All-Purpose Flour – to add crispness
  • Cinnamon – a fave with many desserts
  • Chopped Nuts – optional but adds a nice nutty crunch

Can You Use Frozen Fruit In Your Fruit Crisp?

I most often freeze my blueberries so I can use them all year long. So when I make blueberry crisp I almost always use frozen berries. It turns out perfectly.

Baker’s Note: Keep in mind that frozen fruit can release lots of moisture when it’s cooked. So if a recipe calls for only fresh fruit or berries you’ll want to follow the recipe to keep your filling from being too watery.

But you’re in LUCK! This recipe actually gives you the frozen-blueberry shortcut!

How To Make A Blueberry Crisp?

In 2-Quart Baking Dish (about 8″x8″) make the fruit filling:

Make Filling 

Toss frozen blueberries with lemon zest, lemon juice & vanilla extract.

Mix flour & sugar, sprinkle over blueberries, then fold to coat

Make Topping:

In a separate bowl make the topping:

Mix butter, brown sugar, oats, flour, cinnamon & nuts (if using)

Sprinkle topping over blueberry mixture.

Bake:

Place in 375°F oven & bake 35-40 minutes, or until top is nicely brown and filling is bubbly.

What Kind Of Fruit Can You Use In A Crisp?

You can use various fruits or berries for a fruit crisp, or even mix two or more! Our favorite fruits to bake into a crisp are:

Apples

Blueberries

Peaches

Strawberries

Why Is My Fruit Crisp Topping Soggy?

Too Much Butter– Yeah, I’ve done it too. I’ve gotten carried away with the butter when making the topping thinking it would make it even more buttery.

But all it did was make it soggy. Too much moisture in your crisp is a soggy topping waiting to happen. So it’s best to stick to the recipe.

Locking In Steam – If you’ll be covering your baked crisp, make sure it’s thoroughly cool first. If it’s warm steam will collect on the lid and drop onto your crisp topping, guaranteeing a soggy result.

Improper Reheating – A microwave encourages moist heat, an oven encourages drier heat. So if you’re heating up leftover crisp and want to maintain that amazing crispy topping, opt for oven reheating.

Changing A Recipe – Frozen fruit releases lots of moisture when it’s cooked. So if a recipe calls for fresh fruit or berries you should use only fresh since the recipe has not made allowances for the extra moisture frozen fruit or berries will have. If a recipe references frozen fruit you should be fine to use frozen.
