Ingredients
1 large onion, chopped into 1-inch pieces
butter-flavored cooking spray (such as Pam®)
900 grams ground beef
2 cans (305 g) condensed golden mushroom soup (such as Campbell's®)
340 grams shredded sharp Cheddar cheese
1 package (900 g) frozen bite-size potato nuggets (such as Tater Tots®)
Directions
Step 1
Place the chopped onion in a microwave-safe bowl and cover it with water. Microwave on high until soft, about 7 to 8 minutes, then drain.
Step 2
Preheat the oven to 175°C (350°F). Spray a 23x33 cm (9x13-inch) casserole dish with cooking spray.
Step 3
In a large nonstick skillet, cook and stir the ground beef over medium-high heat until browned and crumbly, about 5 to 7 minutes. Drain and discard the grease.
Step 4
Transfer the cooked beef to the prepared casserole dish and spread the onion pieces evenly over the top. Spread the soup over the onions and sprinkle the Cheddar cheese evenly over the soup. Layer the frozen potato nuggets in rows on top of the cheese.
Step 5
Bake in the preheated oven for 20 minutes. Lightly spray the potato nuggets with cooking spray, and bake for an additional 10 minutes until they are crispy and cooked through.
