What apple makes the best apple crisp?

OK, this topic of the best apples for baking is always up for debate. First and foremost, use whatever apples you have on hand. It is hard to go wrong with a crisp recipe.

Honeycrisp will be your favorite– crunchy and bright, these apples are great for snacking and baking.

Avoid a soft apple that will go mushy during baking. If soft apples are your only option, give it a try but know that the texture of the filling will be softer like applesauce. Not a bad thing, but maybe not ideal for an apple crisp.

Step by Step How to Make this Easy Apple Crisp

Start with the oat crisp topping so that the topping is waiting and ready to go as soon as your filling is done. Having your topping prepared ahead helps reduce the chances of your apples browning. Lemon juice helps slow down the browning but planning your time in the kitchen is a big part of baking this crisp successfully too.

The topping ingredients used here are gluten free (double check that you are buying GF oats) but if you don’t need to prepare the crisp gluten free, you may switch the almond flour for all purpose flour. The almond flour lends its great texture to the dish so consider using it even if you’re not baking for a gluten free crowd.

Ingredients for the easy apple crisp topping before mixing

Simply toss these ingredients together with a fork or a spoon and set the oat topping aside.

Now, let’s move on to the apple filling: apples, lemon juice (to prevent browning), brown sugar, cornstarch, and cinnamon.

Gently toss the filling ingredients together then place in a cast iron skillet. A square, glass baking dish would suffice as well but the presentation of the cast iron skillet is my preference. Press the oat topping onto the apple filling.

The topping can cover as much or as little of the filling as you’d like. This flexibility is another reason this gluten free apple crisp recipe is such as easy one. No fuss. If your topping reaches the edges of your baking dish, great, if not, no big deal. You’ll love it either way.

Place the apple crisp on a foil-lined baking try so that any juicy goodness that bubbles up and over won’t end up on the bottom of your oven. Cleaning your oven later will take the joy right out of baking! Bake at 350 degrees for 45-55 minutes or until the topping is brown and the filling is bubbling away.

Everything was delicious except the amount of was way too salty for my family's taste. I will make it again, but will only use a pinch of salt.
