These Keto Roasted Pecans take just three simple ingredients — butter, salt, and pecans — and completely transform them. The slow oven roast deepens the flavor, enhances their natural sweetness, and gives them that rich, buttery crunch that makes them impossible to stop eating.
They’re the perfect low-carb snack, salad topper, or addition to a charcuterie board.
And the best part? You probably already have everything you need.
If you’ve only ever eaten raw pecans straight from the bag, you are missing out.
Why Roasting Pecans Makes Them Better
Slow roasting pecans in butter:
- Intensifies their natural nutty flavor
- Brings out subtle sweetness (without adding sugar!)
- Creates a crisp, toasty texture
- Makes your kitchen smell amazing
The low temperature keeps them from burning while allowing the butter to soak in slowly.

Ingredients
- 2 cups pecan halves
- 1/2 stick butter (4 tablespoons)
- Salt, to taste (I use about 1/2 to 3/4 teaspoon, but adjust to preference)
If you like them saltier, start with 1/2 teaspoon and increase slightly after roasting if needed.
Instructions
- Preheat oven to 225°F. Line a baking sheet with parchment paper.
- Melt the butter. You can melt it in a small saucepan or microwave until fully liquid.
- Coat the pecans. In a large bowl, mix pecans with melted butter until evenly coated.
- Salt generously. Sprinkle salt over the pecans and stir well. Taste one if you’d like — just remember the flavor intensifies slightly as they roast.
- Bake 1–2 hours. Spread pecans on a parchment-lined baking sheet in a single layer.
Roast for 1–2 hours, stirring every 20–30 minutes. - Cool completely. They will crisp up more as they cool.
