Step-by-Step Instructions
Preparation Steps
1. Preheat the oven. Set your oven to 350°F (175°C). This helps cook the casserole evenly.
2. Heat the skillet. Pour 2 tablespoons of olive oil into a large skillet. Turn the heat to medium.
3. Add the onions and peppers. Toss in ½ cup of finely chopped red onion and 1 medium diced bell pepper. Sauté for about 3-4 minutes. You want them soft but not mushy.
4. Add zucchini and spinach. Mix in 1 small diced zucchini and 1 cup of chopped spinach. Cook for another 2-3 minutes until the spinach wilts. Season with salt, pepper, 1 teaspoon garlic powder, and 1 teaspoon onion powder. Remove from heat and let it cool slightly.
5. Whisk the eggs. In a mixing bowl, crack 8 large eggs. Add 1 cup of heavy cream. Whisk until fluffy and well mixed.
6. Combine ingredients. Stir in 1 cup of shredded cheddar cheese. Then, fold in the sautéed veggie mix until it’s all blended well.
7. Prepare the baking dish. Grease a 9x13 inch baking dish. Pour your mixture into the dish, spreading it out evenly.
Baking Instructions
1. Bake the casserole. Put the dish in the preheated oven. Bake it for 25-30 minutes. Look for a golden brown color on top and a firm center.
2. Check for doneness. You can use a toothpick. Insert it in the center. If it comes out clean, the casserole is ready.
3. Cool and slice. Let it cool for a few minutes before slicing it into squares. This helps the pieces hold their shape.
Serving Suggestions
