Featured Ingredients
- Sweet potato tater tots: The foundation of the dish. They keep their shape while baking and add a mildly sweet, crispy texture.
- Precooked turkey sausage: Using precooked links saves time and still provides the savory protein element. Any precooked sausage will work.
- Cottage cheese: A surprising secret ingredient that makes the egg mixture extra creamy while boosting protein without adding heavy cream.
- Hot sauce: A tablespoon brightens the flavors and balances the sweetness — it adds depth without excessive heat.
- Cheddar cheese: Melted cheddar on top creates a golden, bubbly finish that turns each square into a comforting breakfast bite.
How to Make Sweet Potato Breakfast Casserole
Assembling this casserole is straightforward. Grease a 9×13-inch baking dish, then layer in the frozen sweet potato tater tots, diced onion and green pepper, minced garlic, and chopped precooked turkey sausage. In a bowl, whisk together 12 eggs, one cup of 2% cottage cheese, 1/2 teaspoon salt, and 1 tablespoon hot sauce until smooth. Pour the egg mixture evenly over the contents of the dish, gently pressing so the eggs coat and surround the tots and sausage. Cover the dish for the first part of baking to ensure the eggs set through without the top over-browning. After the covered bake, uncover, add shredded cheddar on top, and finish under higher heat until the cheese is melted and golden. Allow the casserole to rest briefly so it firms up, then slice into nine squares and serve.
Top Tips
- Cover, then uncover: Bake covered for about 45 minutes so the eggs cook evenly, then uncover for the final 15 minutes so the top browns and the tots crisp a bit.
- Let it rest: Rest for 5 minutes after baking to let the casserole set — this makes clean, sturdy slices.
- Ensure egg coverage: Gently press the ingredients down after pouring the eggs so they’re fully submerged and cook uniformly.
- Brand flexibility: Any brand of frozen sweet potato tots works; the recipe is forgiving.
- Protein swaps: Use any precooked sausage, crumbled bacon, diced ham, or plant-based sausage if you prefer.
Variations
- Change the cheese: Try pepper jack, Gruyère, or a Mexican blend for a different flavor profile.
- Swap the protein: Crumbled bacon, diced ham, or plant-based breakfast sausage are all excellent alternatives.
- Add greens: Fold in a couple handfuls of fresh spinach or chopped kale before baking for extra nutrients.
- Include mushrooms: Sliced cremini or baby bella mushrooms work well with the other vegetables.
- Use regular tots: If sweet potato tots aren’t available, regular frozen tater tots are a fine substitute.
Storage
- Refrigerator: Keep leftover squares in an airtight container for up to 5 days.
- Freezer: Wrap individual squares tightly and store in a freezer-safe bag or container for up to 3 months.
- Reheat: Microwave individual portions for 1–2 minutes or reheat in a 350ºF oven for 10–15 minutes until warmed through.
