📖 Instructions

1. **Preheat Your Oven:** Set your oven to 375°F (190°C). This gives it time to reach the correct temperature while you prepare the other components.
2. **Prepare the Potatoes:** Peel and dice your russet potatoes into roughly 1-inch cubes. Place them in a medium pot and cover with cold water. Add a generous pinch of salt. Bring to a boil over high heat, then reduce heat to medium-low and simmer for 10-15 minutes, or until the potatoes are tender when pierced with a fork. Drain the water thoroughly.
3. **Mash the Potatoes:** Return the drained potatoes to the warm pot. Add the milk, butter, a good pinch of salt, and a dash of black pepper. Using a potato masher or a large fork, mash until smooth and creamy. Taste and adjust seasoning as needed. Set aside.
4. **Brown the Beef:** While the potatoes are cooking, heat a large skillet (oven-safe if you prefer a one-pan bake later) over medium-high heat. Add the ground beef and cook, breaking it up with a wooden spoon, until it's fully browned and no pink remains. This usually takes about 6-8 minutes. Drain any excess grease from the skillet.
5. **Sauté Aromatics:** Reduce the heat to medium. Add the chopped onion to the skillet with the browned beef. Cook for 5 minutes, stirring occasionally, until the onion softens and becomes translucent. Stir in the minced garlic and cook for another minute until fragrant.
6. **Build the Base:** Stir the can of corn (drained) into the beef and onion mixture. Pour in the beef broth and Worcestershire sauce. Season with chili powder, cumin, smoked paprika, salt, and pepper. Stir everything together well. Bring the mixture to a gentle simmer and cook for 5 minutes, allowing the flavors to meld and the sauce to thicken slightly.
7. **Assemble the Casserole:** Transfer the beef and corn mixture to a 9x13-inch baking dish if you didn't use an oven-safe skillet. Spread it evenly across the bottom. Carefully spoon the mashed potatoes over the beef and corn layer, spreading them out to cover completely. You can use the back of a spoon or a spatula to create a nice, even top.
8. **Add the Cheesy Topping:** Sprinkle the shredded cheddar cheese evenly over the mashed potato layer. If you like a really crispy topping, you can add a little extra.
9. **Bake to Golden Perfection:** Place the baking dish (or oven-safe skillet) in your preheated oven. Bake for 20-25 minutes, or until the casserole is bubbling around the edges and the cheese topping is melted and beautifully golden brown. If you want an even crispier, darker cheese crust, you can carefully broil it for the last 1-2 minutes, but watch it like a hawk—cheese burns fast!
10. **Rest and Serve:** Once out of the oven, let the Cowboy Casserole rest for 5-10 minutes. This allows it to set slightly, making it easier to serve. Garnish with fresh chopped parsley or chives if you like. Scoop generous portions onto plates and enjoy your comforting, homemade meal!
