This easy 5-ingredient Pecan Brittle recipe is a sweet, crunchy treat that is perfect for gift giving (or keeping all for yourself!).
I love a good old fashioned peanut brittle, but dare I say that this 5-Ingredient Pecan Brittle is even better?!
It’s sweet and crunchy, and tastes like toasted sugar.
Speaking of toasted, the pecans get toasted as the candy cooks, making this treat truly irresistible.
I love packing it up in cellophane bags or tins, and sharing it with our neighbors and friends. A batch of this would also make a lovely homemade Christmas gift!

Do I need a candy thermometer for pecan brittle?
Yes, you do need one special piece of equipment for this: a candy thermometer. You can get one for less than $10, and the thermometer can also be used for deep frying.
Getting an accurate reading on the candy thermometer ensures that the pecan brittle will set up after it’s finished cooking. It also ensures that it doesn’t burn.
You’ll need 5 ingredients for this recipe:
- A combination of sugar and light corn syrup create the sweet, crunchy brittle.
- Water prevents the whole thing from burning too quickly.
- Finely chopped pecans are the star!
- Salt balances out the sweetness nicely.
- Baking soda causes the sugar mixture to foam and make tiny bubbles in the brittle so it’s not rock hard.
How to make easy pecan brittle
Start by preparing a baking sheet. You can either spray it with cooking spray, or place a silicone mat or parchment paper on top.
Then, combine the sugar, corn syrup, water, pecans, and salt in a heavy saucepan. Attach a candy thermometer to the side of the pan.
Place the pan over medium heat and cook until the mixture reaches 290°F.
This took about 20–25 minutes for me, but it all depends on the heat of your stove. Avoid turning the heat any higher than medium, or the mixture will burn.
At the beginning of cooking, there’s enough water in the pan that you’ll only need to stir it every few minutes or so.
As the water evaporates, it’s more likely that the sugar will stick to the bottom of the pan and burn. So, you’ll need to stir it constantly once it reaches 230°F or so. The mixture will heat more quickly after the water evaporates, so keep an eye on that thermometer!
Once it reaches 290°F, take it off the heat and stir in the baking soda. The mixture will foam and bubble.
Quickly spread the mixture onto the prepared baking sheet. Use an offset spatula to smooth it out.
Let the pecan brittle sit for at least 1 hour at room temperature to cool off and firm up.
Then, use your hands to break it into pieces.
You can make the pieces small or large, depending on your preference.
How to store pecan brittle
Pecan Brittle should be stored in an air tight container at room temperature. Like many other candies, it is sensitive to humidity, so you are best off making it on a dry (not rainy) day.
The brittle will keep for up to 3 weeks.
How to freeze pecan brittle
You can freeze pecan brittle in an airtight container for up to 2 months. Place pieces of parchment paper or wax paper in between layers first, so it doesn’t stick together.

Pecan brittle must be cooked to 290°F in order to firm up properly. You really do need a thermometer to make sure it reaches the correct temperature. If you don’t have a candy thermometer, you can also use a meat thermometer or any other kitchen thermometer. Make sure that the thermometer is not touching the bottom of the pan when you take the temperature, which can cause it to read hotter than it really is.
This recipe works well with peanuts, walnuts, pistachios, or almonds.
