This Shepherd's Pie Recipe is a delicious, comforting dish! Meat and vegetables and topped with cheesy mashed potatoes and baked, it is a favorite any time!
Preheat oven to 400° F. Lightly grease a 9x13-inch baking dish or large oven-safe skillet.
Make the mashed potatoes: Place potato chunks in a large pot, cover with cold water + 1 tsp salt. Bring to a boil, then simmer 12-15 minutes until fork-tender. Drain well. In the same pot over low heat, melt ¼ cup butter. Add warmed half-and-half. Mash potatoes until smooth, then stir in butter mixture, cheddar, salt, and pepper. Taste and adjust seasoning. Set aside—keep fluffy!
Cook the filling: Meanwhile, heat olive oil in a large skillet over medium heat. Add onion, carrots, and celery; sauté 5-7 minutes until softened. Add garlic for the last minute. Add ground meat; cook until browned (8-10 minutes), breaking it up. Drain excess fat if needed. Sprinkle flour over meat; stir 1-2 minutes to cook out raw taste. Stir in tomato paste, then broth, Worcestershire, thyme, and peas. Simmer 5-8 minutes until thickened and flavorful. Season to taste. The filling should be saucy but not soupy.
Assemble: Spread filling evenly in baking dish. Dollop mashed potatoes on top, spread to cover completely (optional: use a fork to create ridges for crisp edges). Dot with butter pats.
Bake 20-25 minutes until potatoes are golden and edges bubble. Broil 2-3 minutes for extra browning if desired. Let rest 10 minutes before serving—helps it set!
