Ingredients
  

  • 2 lbs beef
  • 1 onion
  • 3 garlic cloves
  • 1 can soup
  • 1 can corn
  • 4 cups mashed potatoes
  • 1.5 cups cheese
  • 1 bag tater tots

Instructions
 

Step 1: Brown the Beef

  • Heat a large skillet over medium-high heat. Add ground beef, onion, and garlic.
  • Cook 8–10 mins, breaking up the meat with a spatula, until browned. Drain excess grease.
  • Stir in cream of mushroom soup, corn, green beans (if using), Worcestershire sauce, paprika, salt, and pepper. Simmer 5 mins.
  • Pro Tip: For extra flavor, deglaze the skillet with ¼ cup beef broth before adding the soup!

Step 2: Prep the Mashed Potatoes

  • If using instant potatoes, prepare according to package (use extra butter/milk for creaminess).
  • Season with a pinch of salt and pepper.
  • Shortcut: Use leftover mashed potatoes or store-bought refrigerated mash.

Step 3: Assemble the Casserole

  • Preheat oven to 375°F. Grease a 9x13-inch baking dish.
  • Layer 1 (Beuf Mixture): Spread the beef mixture evenly in the dish.
  • Layer 2 (Potatoes): Dollop mashed potatoes over the beef and smooth with a spatula. Sprinkle with 1 cup cheddar cheese.
  • Layer 3 (Tater Tots): Arrange tater tots in tight rows (or haphazardly—your call). Drizzle with olive oil for extra crisp.

Step 4: Bake to Golden Perfection

  • Bake uncovered on the middle oven rack for 35–40 mins, until the tots are golden and the edges bubble.
  • Remove from oven, sprinkle ½ cup cheddar cheese over the tots, and bake 5 more mins to melt.
  • Let cool 5–10 mins (or risk a molten cheese roof-of-mouth burn).
  • Crispy Tot Hack: Broil 2–3 mins at the end for extra crunch!

Step 5: Serve & Garnish

  • Top with sour cream, green onions, hot sauce, or bacon bits. Pair with a simple salad or garlic bread.
