🛒 Ingredients You’ll Need

• Breakfast sausage (1½–2 lbs) – Pork, turkey, spicy, mild—your call.
• Eggs (12 large) – Yes, a full dozen. This is not subtle.
• Milk or half-and-half (2 cups) – Creamier = richer results.
• Shredded cheese (3 cups total) – Cheddar, Colby Jack, or a mix.
• Bread or hash browns (3 cups, optional) – For extra bulk and structure.
• Salt (1½ tsp) – Eggs need it. Always.
• Black pepper (1 tsp) – Freshly cracked if you’re feeling fancy.
• Garlic powder (½ tsp) – Optional, but highly encouraged.
• Butter or cooking spray – To keep things from sticking (and ruining your mood).

Optional add-ins if you’re feeling ambitious:

• Bell peppers
• Onions
• Spinach
• Green onions

👩‍🍳 Step-by-Step Instructions

1. Preheat and prep.
   Heat your oven to 350°F (175°C). Grease a large 9×13-inch baking dish generously. No shortcuts—trust me.
2. Cook the sausage.
   Brown sausage in a skillet over medium heat until fully cooked. Break it into crumbles and drain excess grease.
3. Layer the base.
   Spread bread or hash browns evenly in the dish (if using). Top with cooked sausage.
4. Add the cheese.
   Sprinkle about two-thirds of the shredded cheese over the sausage layer. Yes, cheese layers matter.
5. Whisk the eggs.
   In a large bowl, whisk eggs, milk, salt, pepper, and garlic powder until smooth and slightly frothy.
6. Pour and settle.
   Pour the egg mixture evenly over everything. Press gently so it soaks in nicely.
7. Final cheese moment.
   Sprinkle remaining cheese on top because restraint is overrated.
8. Bake it.
   Bake uncovered for 45–55 minutes until set in the center and lightly golden on top.
9. Rest before slicing.
   Let it sit for 10 minutes. This keeps it from turning into a cheesy landslide.

This casserole delivers high-quality protein from eggs and sausage, which helps keep everyone full and energized. The cheese adds calcium and serious comfort-food vibes.

🚫 Common Mistakes to Avoid

• Skipping the preheat.
  Thinking the oven will magically catch up? Rookie mistake.
• Using raw sausage.
  This isn’t a “trust the process” moment. Cook it first.
• Overbaking.
  Dry eggs are a tragedy. Pull it once the center is set.
• Under-seasoning.
  Eggs without salt are just… sad.
• Cutting too soon.
  Let it rest unless you enjoy breakfast soup.

🔄 Alternatives & Substitutions

• No sausage? Use bacon, ham, or plant-based sausage.
• Vegetarian option? Skip meat and add mushrooms, peppers, and spinach.
• Lower fat? Use part-skim cheese and whole milk instead of cream.
• Extra spicy? Add chili flakes or use hot sausage.
• Low-carb? Skip bread/hash browns and add more veggies.

FYI, this casserole is incredibly forgiving—experiment away.

Can I freeze leftovers?
Absolutely. Freeze slices individually and reheat as needed.

Very. Kids love it. Adults fight over seconds.
