Toss potatoes on a baking sheet with a large drizzle of oil, paprika, 1 tsp Southwest Spice (2 tsp for 4; we’ll use more later), salt, and pepper. Roast on top rack until golden brown, 20-25 minutes. Meanwhile, heat a large, dry pan over medium-high heat. Add bacon. Cook, turning occasionally, until crispy, 6-10 minutes. Transfer to a paper-towellined plate.
