Although toasting the pecans isn’t required, it gives them a lovely texture and deepens their flavor. Toasting pecans is easy but requires a watchful eye because they can burn quickly. To toast pecans, place them on a baking sheet in a 350 degrees F oven for 8-10 minutes, turning halfway through. Alternately, place the pecans in a dry skillet over medium-high heat and stir until the pecans are toasty brown and fragrant.
