Golden tater tots layered over a rich and savory ground beef base make this casserole the kind of meal everyone looks forward to after a long day. The simplicity of the ingredients means you can have it prepped and baking while helping with homework or unwinding from work. It is pure cozy comfort in one pan with just the right amount of creamy, cheesy goodness.
I first made this after a chilly soccer practice when time was tight and everyone was starving. It disappeared faster than anything else I have tried and has been on repeat ever since.
Ingredients
- Ground beef Choose lean beef for less grease and better casserole texture
- Onion Adds sweetness and depth to the base look for firm onions with papery skins
- Frozen mixed vegetables Adds color and nutrition choose blends with peas carrots and corn
- Cream of mushroom soup Brings creaminess and binds ingredients pick a brand with the richest flavor
- Sour cream Adds tang and helps keep the filling moist use full fat for best texture
- Garlic powder Infuses background flavor without overpowering seek out fresh spices
- Salt and pepper Rounds out the flavor use freshly ground pepper for extra kick
- Shredded cheddar cheese Melts beautifully and gives that perfect gooey top opt for sharp cheddar
- Frozen tater tots The crunchy potato crown use straight from the freezer for best crispness
Step-by-Step Instructions
- Brown the Beef and Onion
- Cook your ground beef over medium heat until it is evenly browned and broken up with a spoon. Add the diced onion to the skillet and let it go until just softened and fragrant. This slow sauté is what flavors the whole casserole.
- Season and Combine
- Sprinkle in salt pepper and garlic powder. Next stir in the cream of mushroom soup and sour cream mixing until absolutely everything is coated and smells savory. Stir in the frozen mixed vegetables making sure they are evenly distributed and just starting to thaw.
- Layer in Baking Dish
- Transfer the beef and veggie mixture into a greased 9 by 13 inch baking dish. Use a spatula to spread everything out to the edges so each serving bakes up the same. Sprinkle half of the shredded cheese evenly over the top.
- Arrange Tater Tots
- Working one at a time line up the frozen tater tots in neat rows until the surface is completely covered. Do not overlap as this helps all the tots get crispy.
- Add Cheese and Bake
- Scatter the rest of the cheese over the tater tots making sure some cheese lands on every single one for that irresistible golden crust. Bake at 375 degrees Fahrenheit for 35 to 40 minutes until the topping is crisp and the filling is bubbling hot.
- Rest Before Serving
- Let the casserole sit for five to ten minutes before scooping portions. This little wait helps it set up perfectly and keeps everyone from burning their tongues.

I am always partial to the cheesy crust that forms over the tater tots. My kids and I often argue over who gets the corner pieces with the extra crispy bits—the kind of rivalry only a really great casserole can inspire.
Storage Tips
Store extra casserole in an airtight container in the fridge for up to three days. Reheat in the oven or toaster oven for the crispest tater tots. You can also freeze in portions for a grab and go lunch just thaw and bake until heated through.
Ingredient Substitutions
Feel free to swap in ground turkey or chicken for the beef. You can mix up the vegetables—try bell peppers or broccoli for something different. For a gluten free version look for certified gluten free soup and tater tots.
Serving Suggestions
This casserole is super satisfying on its own but I love serving it with a crisp green salad or pickles to balance the richness. It also makes a fantastic potluck or party dish since it transports well and feeds a crowd.

Tater tot casserole originated in the Midwest as a clever way to stretch pantry ingredients into a belly warming family meal.
