Step by Step Cooking Instructions
Preheat the oven to one hundred eighty degrees Celsius. Grease a nine by thirteen inch baking dish so the casserole does not stick. Spread half of the tater tots in a single even layer across the bottom of the dish. Heat a skillet over medium heat and add a splash of olive oil. Sauté the chopped onion and bell pepper until they soften. Add the cooked crumbled sausage and stir to combine. Sprinkle in garlic powder and a little black pepper. Taste a small piece and adjust seasoning. Spread the sausage vegetable mix over the layer of tater tots. Scatter the remaining tater tots on top to form a crisping lid.
Whisk eggs and milk in a large bowl until smooth. Add shredded cheese half now and half later. Season the egg mixture with salt and a touch more black pepper. Pour the egg and milk mixture slowly over the casserole so liquid seeps into crevices. Press down gently with the back of a spoon to help the custard reach the bottom layer. Cover the dish with foil and refrigerate for at least four hours or overnight to allow the flavors to marry.
When ready to bake remove the casserole from the fridge and let it sit for about thirty minutes to reduce chill. Preheat the oven if needed. Bake covered for thirty five minutes. Remove the foil and sprinkle the remaining cheese across the top. Return the dish to the oven and bake uncovered for fifteen to twenty minutes until the tater tots are golden and the center is set. A knife inserted into the center should come out clean or with a few moist crumbs. Let the casserole rest for five to ten minutes so the custard firms and slicing is easier. Garnish with chopped parsley. Serve warm with hot sauce available for those who enjoy a kick.
Tips for Customizing the Recipe
Change the protein to suit taste and budget. Use diced ham, shredded rotisserie chicken or crumbled bacon. For a vegetarian plate skip the meat and add sautéed mushrooms and spinach. Vary the cheese. Pepper jack adds zip. Swiss melts into a silky layer. Use a mix of cheeses for depth.
Adjust texture with potato choices. Use hash brown patties broken into pieces for a softer top. For extra crunch under the cheddar add a light layer of panko crumbs just before the final bake. Control moisture by draining juicy vegetables and by avoiding watery tomatoes unless they are roasted first.
Make a low carb version by replacing tater tots with roasted cauliflower florets. Keep the same egg and cheese base and roast the cauliflower until lightly caramelized before assembling. For a crowd pack several pans at once and bake simultaneously while staggering oven timing.
Plan timing for convenience. Assemble the night before and refrigerate. Let the dish come closer to room temperature before baking. If you must bake from cold add ten to fifteen minutes to the covered baking time.
Nutritional Information
Each serving equals about one eighth of the recipe. Calories vary with sausage choice and cheese amount. Expect calories around six hundred to seven hundred per serving with full fat ingredients. Protein is substantial thanks to eggs and meat. Fat comes mainly from cheese, sausage and olive oil. Carbohydrates are moderate with potatoes as the main source. Fiber increases if you add more vegetables like bell pepper and onion. Sodium can be high with processed meats and salted cheese so choose low sodium options when needed. For lighter plates reduce cheese, use leaner protein, and bulk up with vegetables.
Serving Suggestions

Serve the casserole with a simple fruit bowl to add sweetness and acidity. A crisp green salad with a lemon vinaigrette cuts through richness. Offer warm biscuits or crusty bread for those who want extra carbs. Coffee and tea pair naturally with this breakfast style dish. For brunch present condiments such as hot sauce ketchup and a bowl of chopped herbs. Leftovers reheat well in a low oven or in individual portions in a microwave.

Tater tot breakfast casserole brings comfort with minimal fuss. The recipe scales easily and travels well for gatherings. Small steps like draining vegetables and letting the casserole rest before slicing make a big difference. Swap proteins and cheeses to suit your pantry and your guests.
