Ingredients
- Ground beef: brings savory flavor and rich texture Opt for lean or regular beef depending on your taste
- Onion: finely chopped for gentle sweetness and depth Choose a firm onion with tight skin
- Garlic: adds warmth and fragrance Go for fresh cloves rather than jarred for best results
- Canned sweet corn: gives pops of sweetness Look for kernels that are plump and bright
- Canned black beans or kidney beans: boost protein and fiber Make sure to rinse beans well to remove excess salt
- Cream of mushroom soup: creates the creamy comforting base Use your favorite brand and check for a creamy consistency
- Sour cream: balances everything with tang and richness Go for full fat for a heartier casserole
- Shredded cheddar cheese: melts into gooey goodness Try a sharp cheddar for extra punch and shred it yourself if possible
- Frozen tater tots: deliver crispiness and fun Look for a bag with intact tots and minimal freezer burn
- Salt and black pepper: round out the flavors Season with freshly cracked pepper for best flavor
- Chopped green onions or jalapeños: make an optional garnish Fresh and bright or spicy if you like heat
Step-by-Step Instructions
- Prepare the Filling:
- Preheat your oven to 375 degrees Fahrenheit or 190 degrees Celsius Cook ground beef in a large skillet over medium heat for about eight minutes breaking it up as you go until it is fully browned and sizzling Drain away any extra fat so the casserole does not get greasy
- Sauté the Aromatics:
- Add your finely chopped onion and minced garlic to the skillet with the beef Sauté everything together for two to three minutes Stir frequently until the onions lose their raw edge and the garlic is fragrant This step lets the base flavors come together
- Combine and Season:
- Stir in the drained sweet corn and beans followed by the cream of mushroom soup and sour cream Sprinkle in salt and black pepper to taste Mix everything well until creamy and evenly combined You will see all the colors from the vegetables swirled through the sauce
- Assemble the Casserole:
- Coat a nine by thirteen inch baking dish lightly with oil or nonstick spray Pour in your beef filling and spread it out so every bite will be cheesy and moist Sprinkle the shredded cheddar cheese over the hot beef mixture so it melts better Lay the frozen tater tots gently in a single layer covering the whole surface do not overlap so they get crispy
- Bake Until Golden:
- Place the dish on the oven middle rack and bake for thirty to thirty five minutes The tater tots will turn golden brown and crackle when touched For extra crispiness set the oven to broil for an extra two to three minutes but watch closely so the top does not burn
- Add the Finishing Touches:
- Let the casserole rest for five minutes after baking so it sets up and is easier to slice Scatter green onions or jalapeños on top if you like a little freshness or kick Serve immediately and watch how quickly seconds disappear

I always look forward to the sharp cheddar cheese bubbling up around the edges It is my reminder that the dish is ready and it brings everyone to the table The best family moments happen when we all dig in straight from the big casserole dish
Storage Tips
This casserole keeps well wrapped tightly or in containers in the fridge for up to four days Just reheat portions in the oven or microwave until piping hot The tater tots are crispiest when reheated in an oven or air fryer If you want to freeze wrap cooled portions well and freeze for up to two months Thaw overnight in the fridge before reheating
Ingredient Substitutions
Ground turkey or chicken work well in place of beef You can also use a plant based crumbled protein for a vegetarian option Change up the beans with pinto or cannellini beans Try cream of chicken soup for a milder flavor or add red bell peppers for sweetness If you do not have cheddar mozzarella or a blend of shredded cheeses gives a nice stretchy melt
Serving Suggestions
This is hearty on its own but you can pair it with a crisp green salad or some roasted broccoli for extra veggies My kids love it with a side of ketchup or ranch for dipping For a party or potluck offer hot sauce and lots of fresh herbs at the table
