Servings: 12 servings
Calories: 388kcal
Ingredients
- 1 pound bulk pork breakfast sausage
- 1 medium onion diced
- 1 red bell pepper diced
- 8 large eggs at room temperature
- 2 cups whole milk
- 1 teaspoon garlic powder
- ½ teaspoon pepper
- 1 ½ cups Colby jack cheese divided
- 28 oz frozen tater tots
Instructions
- Preheat your oven to 350°F and grease a 9x13 inch casserole pan.
- In a medium skillet, combine the sausage, onions, and bell peppers over medium heat. Cook until the sausage has browned and crumbled. Drain the grease from the sausage mixture and spread it in the casserole dish.
- In a large mixing bowl, whisk together the eggs, milk, garlic powder, and pepper. Pour the egg mixture over the sausage mixture.
- Sprinkle half the cheese and the tater tots into the baking dish.
- Bake the casserole in the preheated oven for 40 minutes. Sprinkle the remaining cheese on the top of the casserole and bake for an additional 5 minutes.
Notes
Make-Ahead Tips:
- Assemble the casserole the night before (skip adding tater tots until baking). Cover and refrigerate overnight.
- If chilled, add 5–10 extra minutes to baking time.
- Freeze unbaked casserole (minus tots) up to 2 months. Thaw overnight before baking.
- Or freeze baked casserole once cooled. Wrap tightly and reheat individual slices at 325°F for 20 minutes.
- Use a mix of red and green peppers for festive color or toss in chopped zucchini, spinach, or green onions.
- For creamier texture, stir in ¼ cup sour cream or cottage cheese before baking.
- Sharp cheddar adds great flavor, but mozzarella, Swiss, or Monterey Jack all work too.
- The casserole is done when the center is set but still has a slight jiggle.
- Let it rest 5–10 minutes before slicing so it sets up nicely.
- Tent loosely with foil if the edges brown too quickly.
- Pair with fruit salad, cinnamon rolls, or my Stuffed French Toast Casserole.
- Perfect for holiday brunches, harvest mornings, or feeding a hungry crew.
- Write baking or reheating instructions right on the foil before freezing. It’s one less thing to remember when life’s moving fast!
