Essential Ingredients for a Perfect Baked Feta Egg Casserole
Here’s a carefully curated list of ingredients you’ll need. Feel free to adjust quantities or add optional ingredients based on your taste preferences.
Main Ingredients
- 6 large eggs — the protein-packed foundation.
- 1 cup milk (or substitute heavy cream for extra richness).
- 1 cup crumbled feta cheese — delivers the signature tangy creaminess.
- 1 cup cherry tomatoes, halved — juicy bursts of sweetness.
- 1 cup fresh spinach, roughly chopped — adds color and nutrients.
- ½ cup diced red bell pepper — for a mild crunch and vibrant flavor.
- ½ cup diced onion — aromatic base.
- 1 tbsp olive oil — for sautéing.
- Salt and freshly ground black pepper — to taste.
Optional Additions
- ½ cup cooked sausage or bacon, crumbled — for extra protein and smoky flavor.
- ¼ cup fresh basil, chopped — adds herbal freshness.
- ¼ tsp red chili flakes — for a gentle spicy kick.
- Other veggies like zucchini, mushrooms, or asparagus — great for variety.
- Kalamata olives and oregano — to give a Greek-inspired twist.
Step-by-Step Preparation: How to Make Your Baked Feta Egg Casserole
Follow these simple steps to create a flawless, golden casserole that will impress any crowd.
1. Prepare Your Ingredients and Oven
- Preheat the oven to 375°F (190°C). This ensures even baking and a nicely browned top.
- Sauté your vegetables: Heat olive oil in a skillet over medium heat. Add diced onions and bell peppers, seasoning lightly with salt. Cook for 3-5 minutes until they soften and release their aroma.
- Add the chopped spinach and cook until wilted, about 1-2 minutes. Remove from heat and allow to cool slightly.
2. Whisk Your Egg Mixture
- In a large bowl, combine the eggs, milk (or cream), salt, and pepper. Whisk thoroughly until the mixture is smooth and slightly frothy—this aerates the eggs, helping the casserole stay fluffy.
3. Assemble the Casserole
- Lightly grease a 9×9-inch baking dish with butter or non-stick spray.
- Spread the sautéed vegetables evenly on the bottom.
- Scatter the halved cherry tomatoes and crumbled feta cheese over the veggies.
- If you’re using optional add-ins like cooked sausage or herbs, sprinkle them now.
- Carefully pour the egg mixture over the layered ingredients, ensuring an even spread.
4. Bake to Perfection
- Place the dish in the oven and bake for 25-30 minutes.
- The casserole is done when the eggs are set (no longer jiggly in the center) and the top is a light golden color.
- Use a knife or toothpick inserted into the center to check doneness—it should come out clean.
5. Rest Before Serving
- Let the casserole rest for 5-10 minutes after baking to allow it to firm up and slice neatly.
- Serve warm, garnished with fresh herbs or a drizzle of olive oil if desired.
Delicious Serving Suggestions and Pairings
Enhance your meal with complementary sides and toppings:
- Toasted bread or bagels: Perfect for sopping up any creamy egg.
- Simple green salad: Light and refreshing to balance the richness.
- Roasted potatoes or crispy hash browns: Classic breakfast pairings.
- Toppings: Add a sprinkle of red chili flakes, fresh basil, parsley, or a drizzle of balsamic glaze for extra flavor layers.

Don’t Overbake
