Ingredients

• 1 pound Ground Italian sausage
• 2 tablespoons Olive oil
• 3 pieces Garlic cloves, minced
• 1 medium Onion, chopped
• 2 medium Bell peppers, diced
• 2 medium Zucchini, sliced
• 1 cup Cherry tomatoes, halved
• 2 cups Spinach, fresh
• 6 large Eggs, beaten
• 1 cup Heavy cream
• 1 cup Cheddar cheese, shredded
• 0.5 cup Parmesan cheese, grated
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 teaspoon Dried oregano
• 2 tablespoons Fresh parsley, chopped (for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

In a large skillet, heat olive oil over medium heat.

Step 3

Add the ground Italian sausage and cook until browned, breaking it up with a spatula, about 5-7 minutes. Remove the cooked sausage from the skillet and set aside.

Step 4

In the same skillet, add the minced garlic and chopped onion. Sauté until the onion becomes translucent, about 3-4 minutes.

Step 5

Add the diced bell peppers and sliced zucchini to the skillet. Cook for another 5 minutes, or until the vegetables are slightly tender.

Step 6

Stir in the halved cherry tomatoes and fresh spinach, cooking until the spinach is wilted, about 2 minutes.

Step 7

Return the cooked sausage to the skillet, mixing everything well.

Step 8

In a large mixing bowl, whisk together the beaten eggs, heavy cream, shredded cheddar cheese, grated Parmesan cheese, salt, black pepper, and dried oregano.

Step 9

Fold the sausage and vegetable mixture into the egg and cheese mixture.

Step 10

Pour the entire mixture into a greased 9x13-inch baking dish.

Step 11

Smooth out the top with the back of a spoon, and transfer the dish to the preheated oven.

Step 12

Bake for 30-35 minutes, or until the casserole is set and the top is golden brown.

Step 13

Remove the casserole from the oven and let it cool slightly before serving.

Step 14

Garnish with freshly chopped parsley before serving.
