Step-by-Step Instructions

Step 1: Preheat and Prep

1. Preheat your oven to 375°F (190°C).
2. Lightly grease a 9×13 inch baking dish with non-stick spray or a little butter. Set aside.

Step 2: Cook the Turkey Sausage

1. In a large skillet over medium heat, cook the turkey sausage until fully browned, about 6–8 minutes.
2. Break it into small crumbles as it cooks.
3. Drain any excess liquid and remove from heat.

Step 3: Sauté the Vegetables

1. In the same pan, add a drizzle of olive oil if needed.
2. Sauté the diced onion and bell pepper for 3–4 minutes, until softened.
3. Add chopped spinach and cook for another minute until wilted.
4. Remove from heat and let cool slightly.

Step 4: Mix the Egg Mixture

1. In a large mixing bowl, whisk together eggs and milk until well combined.
2. Stir in garlic powder, onion powder, black pepper, and salt.
3. Add the shredded cheddar and mozzarella cheeses, mixing gently.

Step 5: Assemble the Casserole

1. Spread the cooked turkey sausage evenly in the prepared baking dish.
2. Layer the sautéed veggies over the sausage.
3. Pour the egg and cheese mixture evenly over everything.
4. Use a spatula to gently press down and distribute ingredients.

Step 6: Bake the Casserole

1. Place the casserole in the preheated oven.
2. Bake for 30–35 minutes, or until the center is set and the top is golden.
3. A knife inserted in the center should come out clean.
4. Let cool for 5–10 minutes before slicing.

Step 7: Slice, Serve & Enjoy

1. Cut into squares and serve warm.
2. Top with hot sauce, salsa, or a dollop of Greek yogurt if desired.

Tips for a Perfect Egg Casserole
Use Room Temperature Eggs – Helps everything bake evenly.
Let It Rest – Allow the casserole to cool slightly before slicing to avoid messy pieces.
Add Variety – Use leftover roasted veggies, different cheeses, or turkey bacon for new twists.
Make It Dairy-Free – Use almond or oat milk and a dairy-free cheese alternative.

Serving Suggestions
Fresh Fruit Salad – A bright, refreshing side to balance the savory casserole.
Whole Grain Toast or English Muffins – Perfect for soaking up the cheesy egg goodness.
Green Smoothie – A nutrient-packed drink for a complete breakfast.
