How to Make Tater Tot Breakfast Casserole Recipe
Step 1: Cook the Sausage and Onions
Start by heating a skillet over medium heat and cooking your breakfast sausage until it’s beautifully browned and no longer pink. Breaking it into crumbles ensures every bite has that savory, meaty punch. Toss in the diced onion and sauté together for about 3 minutes to soften and sweeten the onion, creating a flavorful base. Once done, drain off any excess grease so your casserole isn’t too oily.
Step 2: Assemble the Sausage and Cheese Layers
Spread the cooked sausage and onion mixture evenly across a greased 9×13-inch baking dish. Next, sprinkle the shredded cheddar cheese all over the sausage, followed by the mozzarella. This cheese duo melts into a luscious, gooey layer that pairs perfectly with the crispy tots we’ll add next.
Step 3: Arrange the Tater Tots
Place the frozen tater tots in a single layer atop the cheesy sausage mixture. This layer will crisp up beautifully in the oven, adding texture contrast and that irresistible golden color to the casserole’s top.
Step 4: Whisk and Pour the Egg Mixture
In a medium bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper until fully combined. Pour this creamy egg custard gently and evenly over the tater tots, letting it seep into every nook between the crispy tots below. This step binds everything together while creating a soft, tender interior.
Step 5: Bake to Perfection
Pop your casserole into the preheated 350°F oven and bake for 45 to 50 minutes. You’ll know it’s ready when the egg custard is set and the top boasts a beautiful golden brown hue. Allow it to rest for 5 to 10 minutes before slicing, letting flavors marry and your casserole set perfectly for neat servings.
