🛒 Ingredients

  • 12–16 oz breakfast sausage

  • ½ cup diced onion
  • 6 large eggs (or up to 10 for more protein)

  • ½ tsp salt + black pepper
  • 24 oz frozen tater tots
  • 1 cup cheddar + 1 cup Monterey Jack (grated)

👨‍🍳 How to Make It (Overnight or Same-Day)

1. Cook the Filling
Brown the sausage with onions and peppers in a skillet. Drain and set aside.

2. Build the Layers

  • Grease a 9×13” pan.
  • Add frozen tater tots in a single layer.
  • Top with cooked sausage/veggies, then shredded cheese.

3. Add Egg Mixture
Whisk together eggs, milk, sour cream, salt, and pepper. Pour evenly over the pan.

4. Refrigerate Overnight
Cover with foil and chill for up to 18 hours.

OR
Bake immediately (the tots will hold their shape more, but it’s still delicious!).

5. Bake
Bake covered at 350°F for 25 minutes. Uncover and bake another 20–25 minutes until set and golden.
