Ingredients

• 1 pound Breakfast sausage (ground, mild or spicy)
• 3 pieces Zucchini (medium-sized)
• 8 large Eggs
• 0.5 cups Whole milk
• 1.5 cups Shredded cheddar cheese
• 0.25 cups Parmesan cheese (grated)
• 1 piece Onion (small, diced)
• 2 cloves Garlic (minced)
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 0.5 teaspoons Paprika
• 1 tablespoon Olive oil
• 2 tablespoons Fresh parsley (chopped, optional)
• 0 n/a Cooking spray

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with cooking spray.

Step 2

Heat a large skillet over medium heat. Add the sausage and cook, breaking it apart with a spoon, until browned and fully cooked (about 7-9 minutes). Transfer the cooked sausage to a paper towel-lined plate to drain excess grease.

Step 3

In the same skillet, add 1 tablespoon of olive oil, followed by the diced onion. Sauté the onion for 3-4 minutes until softened, then add the minced garlic and cook for an additional minute until fragrant.

Step 4

While the onion and garlic are cooking, shred the zucchini using a box grater and transfer it into a clean kitchen towel. Squeeze out as much excess moisture as possible from the zucchini to prevent a watery casserole.

Step 5

In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and paprika until well combined.

Step 6

Stir in the cooked sausage, sautéed onion and garlic, shredded zucchini, cheddar cheese, and Parmesan cheese. Mix everything thoroughly.

Step 7

Pour the mixture into the prepared baking dish, spreading it evenly with a spatula.

Step 8

Bake the casserole in the preheated oven for 40-45 minutes, or until the top is golden brown and the center is set. You can test for doneness by inserting a knife into the center—it should come out clean.

Step 9

Allow the casserole to cool for about 5 minutes before slicing it into portions.

Step 10

Optional: Garnish with fresh chopped parsley before serving for an extra pop of color and flavor.
