Step 1

• Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce. • Trim, peel, and cut carrots on a diagonal into 1-inch-thick pieces. Halve, peel, and cut onion into 1/2-inch-thick wedges; mince a few wedges until you have 1 TBSP (2 TBSP for 4 servings). • Toss carrots and onion wedges on a baking sheet with a large drizzle of oil, salt, and pepper. • Roast on top rack until browned and tender, 25-30 minutes.

Step 2

• While veggies roast, dice potatoes into 1/2-inch pieces. (TIP: For a smoother texture, peel potatoes first.) Place in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 15-20 minutes. • Reserve 1/2 cup potato cooking liquid, then drain and return potatoes to pot. • Keep covered off heat until ready to mash.

Step 3

• While potatoes cook, pat pork* dry with paper towels. Season all over with salt and pepper. • Heat a drizzle of oil in a large pan over medium-high heat. Add pork and cook until browned and cooked through, 4-6 minutes per side. • Turn off heat; transfer pork to a cutting board. Wipe out pan. • Meanwhile, strip rosemary leaves from stems; finely chop leaves until you have 2 tsp (3 tsp for 4 servings). Swap in chicken for pork. Cook chicken until cooked through, 3-5 minutes per side.

Step 4

• Heat a drizzle of oil in pan used for pork over medium heat. Add minced onion and chopped rosemary. Cook, stirring often, until onion is softened, 2-3 minutes. • Add stock concentrate and 1/4 cup water (1⁄3 cup for 4 servings). Bring to a simmer and cook until slightly thickened, 3-4 minutes. • Turn off heat and stir in 1 TBSP butter (2 TBSP for 4) until melted.

Step 5

• Return pot with drained potatoes to medium-low heat. Add sour cream and 1 TBSP butter (2 TBSP for 4 servings). Mash until smooth, adding splashes of reserved potato cooking liquid as needed. Season generously with salt and pepper.

Step 6

• Slice pork crosswise. • Divide pork, mashed potatoes, and veggies between plates. Top pork with sauce and serve. Slice chicken crosswise. Chicken is fully cooked when internal temperature reaches 165°.
