Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan. This step is crucial as it prevents the casserole from sticking and makes cleanup a breeze.
Next, take the frozen tater tots and spread them evenly on the bottom of the prepared pan. Aim for minimal overlap to achieve that delightful crispiness. This is where the base of your casserole is formed.
In a mixing bowl, add the sour cream, cream of chicken soup, and shredded cheddar cheese. Mix everything together well until you achieve a uniform mixture. This creamy layer is what makes the casserole so comforting and flavorful.
Now, take the creamy mixture and spread it evenly over the layer of tater tots. Make sure to cover them thoroughly; you want every single tot to be enveloped in that rich goodness.
Sprinkle the French fried onions generously on top of the creamy mixture. This provides a wonderful crunch and flavor contrast once baked.
Place the baking dish in the preheated oven and bake for 40 to 45 minutes. Keep an eye out for the edges to be bubbly and the top to be golden brown; this indicates that it’s ready to come out.
Once done, carefully remove the casserole from the oven. Let it sit for a few minutes to set before serving. This allows the flavors to meld beautifully.
Before serving, top the casserole with chopped fresh tomatoes and parsley. The freshness of these toppings adds not only flavor but also a nice visual appeal.
Serve it warm and enjoy the delightful blend of flavors and textures. You’ll be amazed at how quickly it disappears!
