Start by soaking the peanuts in water. Add 3 cups of water to a bowl, and mix in 1 cup of kosher salt. Stir until the salt dissolves, then add the peanuts. Let them soak for about two hours. This step ensures that the peanuts absorb flavor and moisture for a perfect roast.

While your peanuts soak, preheat your oven to 325°F (163°C). A properly heated oven ensures even roasting, leaving you with nuts that are crispy all around.

After soaking, drain the peanuts and spread them on a clean kitchen towel. Pat them dry gently. You want to remove excess moisture but maintain some saltiness.

Transfer the dry peanuts into a mixing bowl. Add the garlic powder and smoked paprika. Toss them well to coat each nut evenly. This step is critical for balancing the flavors.

Spread the seasoned peanuts on a single layer on a baking sheet. Bake for about 30 minutes, stirring halfway through. Keep an eye on them! Ovens vary, and you want a golden-brown color.

After roasting, remove the peanuts and let them cool down completely. Once cooled, store them in an airtight container. Proper storage helps maintain their crunch.
