A hearty beef and bean chili base is topped with gooey melted cheddar cheese and finished with crispy tater tots.
Preheat the oven to 350 degrees.
In a saute pan, cook the hamburger and the onion until the hamburger is well browned. Drain off the fat and return to the pan. Add the chili seasoning, chili tomatoes, condensed tomato soup and chili beans. Mix well and pour into a 9x13 pan.
Spread the shredded cheddar cheese over the chili mixture. Layer the tater tots evenly over the top. Bake at 350 degrees for 45-60 minutes or until bubbly and the tater tots have nicely browned and crisped on top.
To prepare ahead of time, assemble the casserole and cover with foil. Place in the refrigerator for up to 3 days. If using a glass pan, let the pan come to room temperature before baking and bake as normal.
