Pro Tips and Substitutions

Shortcut: Use pre-cooked sausage or a breakfast sausage blend for even quicker preparation.
Pan Options: You can also bake this recipe in a 13×9 casserole dish. Simply make the cook the sausage and onions in a large skillet, transfer to your baking dish, then proceed with the recipe as written.
Make Ahead: Prepare the casserole the night before and refrigerate. Just add an extra 10-15 minutes to the baking time if baking straight from the fridge.
Sausage: Substitute turkey sausage, chicken sausage, Italian sausage, smoked sausage, or a plant-based sausage for a lighter or vegetarian version.
Cheese: Try swapping cheddar cheese for Monterey Jack, Colby jack, pepper jack cheese, or a dairy-free cheese alternative.
Vegetables: Use a mix of your favorite veggies—spinach, zucchini, or sautéed mushrooms make great additions!
Tots Tip: The tater tots should be frozen when baked to avoid overcooking. Shredded or diced frozen hash browns can be a great alternative to tater tots. Just make sure they are well compressed to create a nice crispy topping.
