Tools You’ll Need

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.
