  • 1 red bell pepper, diced
  • 2 cups frozen diced potatoes (or hash browns), thawed
  • 10 large eggs
  • ½ cup milk (any kind)
  • 1 tsp garlic powder
  • 1 tsp Italian seasoning or dried oregano
  • ½ tsp salt
  • ¼ tsp black pepper
  • 1 ½ cups shredded cheddar or Monterey Jack cheese
  • Optional: fresh parsley or green onions for garnish

Tools You’ll Need

  • 9×13 inch baking dish
  • Large skillet
  • Mixing bowls
  • Whisk and spatula
  • Oven mitts

Step-by-Step Instructions

Step 1: Preheat the Oven
Preheat oven to 375°F (190°C).
Grease a 9×13 inch baking dish with cooking spray or a little oil.

Step 2: Cook the Turkey Sausage
In a large skillet over medium heat, cook turkey sausage until browned and fully cooked, breaking it up as it cooks (5–7 minutes).
Remove to a bowl and set aside.

Step 3: Sauté the Veggies
In the same skillet, add a bit of oil if needed.
Sauté the onion and bell pepper until soft, about 4–5 minutes.
Stir in the thawed diced potatoes and cook for another 2 minutes.
Combine with the cooked sausage.

Step 4: Assemble the Casserole
Spread the sausage, veggies, and potato mixture evenly into the greased baking dish.
Sprinkle with half of the shredded cheese.

Step 5: Make the Egg Mixture
In a large bowl, whisk together the eggs, milk, garlic powder, Italian seasoning, salt, and pepper until well combined.

Step 6: Pour and Top
Pour the egg mixture evenly over the sausage and veggies in the baking dish.
Top with the remaining cheese.

Step 7: Bake
Bake uncovered for 35–40 minutes, or until the eggs are set and the top is golden brown.
A knife inserted in the center should come out clean.
Let rest for 5–10 minutes before slicing and serving.

Tips for the Best Egg Casserole
Use Thawed Potatoes – Prevents excess moisture in the dish.
Shred Your Own Cheese – Melts better and gives a creamier texture.
Let It Rest – Casserole slices cleaner and holds together better after resting.
Make It Spicy – Add jalapeños, pepper jack cheese, or a dash of hot sauce.
Add Greens – Stir in a handful of spinach or kale for extra nutrients.

Serving Suggestions
With Fresh Fruit – Light and refreshing contrast to the hearty casserole.
With Toast or Biscuits – For a classic breakfast pairing.
With Avocado Slices – Adds creaminess and healthy fats.
With Salsa – Spoon over for a zesty flavor boost.
With Coffee or Orange Juice – Completes the brunch experience.

How to Store & Reheat

Storing:
Refrigerate: Cover and store leftovers in the fridge for up to 4 days.
Freeze: Wrap individual portions tightly and freeze for up to 2 months.

Reheating:
Microwave: Heat slices on medium power for 1–2 minutes.
Oven: Reheat at 350°F for 10–15 minutes until warmed through.
Air Fryer: Great for a quick crisp reheat at 375°F for 5–6 minutes.

Frequently Asked Questions

1. Can I use fresh potatoes instead of frozen?
Yes—just dice and parboil them first to ensure they’re tender when baked.

2. Can I use egg whites or an egg substitute?
Absolutely—substitute some or all of the eggs with egg whites or a liquid egg substitute to lighten it up.

3. Can I prep this the night before?
Yes—assemble everything and refrigerate. Bake in the morning, adding 5–10 extra minutes to the cooking time.

4. What other veggies can I use?
Mushrooms, zucchini, broccoli, spinach, or green onions all work great.

5. Can I use a different protein?
Sure! Try chicken sausage, ground turkey, or veggie sausage crumbles for variety.
