Pro Tips

Instructions
Step 1: Cook the Sausage and Veggies
In a skillet over medium heat, cook 1 pound of breakfast sausage until browned and crumbled. Add ½ diced onion and 1 diced red bell pepper and sauté for 3–4 minutes until soft. Remove from heat and let cool slightly.

Step 2: Prep the Cornbread
Crumble 2 cups of cornbread into a large mixing bowl. Try to keep some larger chunks for texture.

Step 3: Mix the Eggs
In a separate bowl, whisk together 6 large eggs, 1 ½ cups whole milk, ½ tsp garlic powder, ½ tsp salt, and ¼ tsp black pepper until smooth.

Step 4: Combine Everything
In a large bowl, add the crumbled cornbread, cooked sausage and veggie mix, 1 cup shredded cheddar cheese, ½ cup shredded mozzarella cheese, and the egg mixture. Stir gently to combine.

Step 5: Pour into Dish
Lightly grease a 9×13 baking dish with butter or nonstick spray. Pour in the mixture and spread it evenly.

Step 6: Bake
Bake at 375°F (190°C) for 35–40 minutes, until golden brown on top and a knife in the center comes out clean.

Step 7: Garnish and Serve
Let the casserole rest 10 minutes, then garnish with 2 sliced green onions. Slice and serve warm.

Leftovers and Storage
- Store in an airtight container in the fridge for up to 4 days.
- Reheat individual servings in the microwave for 1–2 minutes.
- You can also freeze it (sliced or whole) for up to 2 months. Wrap tightly in foil and reheat in the oven at 350°F.

Why This Recipe Works (Quick Science)
This recipe works because the cornbread soaks up the egg and milk mixture like a sponge, keeping everything moist without getting soggy. Sausage adds protein and fat, which gives it richness, while the cheese helps bind everything and gives that gooey, savory finish.
Common Mistakes
- Using fresh cornbread: It can turn mushy. Use day-old or slightly dried-out cornbread.
- Overmixing: Stir just until combined. Overmixing can make the casserole dense.
- Not letting it rest: This helps it set so you get clean slices.
- Not greasing the pan: Always grease well or it might stick.
What to Serve With
- Fresh fruit salad or sliced oranges
- A hot cup of coffee or tea
- Yogurt parfaits
- Simple green salad if you’re eating it for brunch
- Hot sauce or salsa on the side
FAQ
Can I use store-bought cornbread mix?
Yes! Just bake it first and let it cool before crumbling.
Can I make it vegetarian?
Sure—swap the sausage for a plant-based version or use sautéed mushrooms and spinach.
Can I bake it in a smaller dish?
Yes, but you’ll need to adjust the baking time. Deeper dishes may need 5–10 extra minutes.
Does it taste good the next day?
Absolutely. Some say it’s even better reheated!
