Instructions

1. Step 1: Preheat oven to 400°F. In a large skillet, heat 2 tbsp olive oil over medium heat. Add 1 large diced yellow onion and cook for 10 minutes, stirring occasionally, until deeply golden and caramelized.
2. Step 2: Add 3 minced garlic cloves and cook for 1 minute until fragrant. Stir in 1 lb ground beef, breaking it up with a spoon, and cook for 6-8 minutes until browned and no longer pink.
3. Step 3: Mix in 2 tbsp tomato paste, 1 cup sweet corn kernels, 1 tbsp Worcestershire sauce, 1 tsp chopped fresh thyme, 1 cup beef broth, 1 tsp salt, and 1/2 tsp black pepper. Simmer for 8 minutes until thickened and flavorful.
4. Step 4: Meanwhile, place 3 peeled and cubed russet potatoes into a large pot of salted water (1 tsp salt). Bring to a boil and cook for 15 minutes until fork-tender. Drain well.
5. Step 5: Mash potatoes with 4 tbsp unsalted butter, 1/2 cup whole milk, 1/2 tsp salt, and 1/2 tsp black pepper until smooth and creamy.
6. Step 6: Transfer beef mixture to a 9x9-inch baking dish and spread evenly. Dollop mashed potatoes on top and spread with a spatula to cover the filling.
7. Step 7: Bake uncovered for 20 minutes until the edges bubble and the potato topping is golden brown. Let rest for 5 minutes before serving.
