Chicken and Spinach Egg Cups: Step-by-Step Guide

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This will ensure your egg cups bake evenly.
Step 2: Sauté the Vegetables
In a skillet, heat the avocado oil over medium heat. Add the finely chopped yellow onion and red bell pepper. Sauté for about 5-7 minutes, or until the vegetables are soft and fragrant. Stir in the baby spinach and cook until wilted, about 1-2 minutes. Remove from heat and let cool slightly.
Step 3: Prepare the Egg Mixture
In a large mixing bowl, crack the 5 large eggs and add the egg whites. Whisk together until well combined. Season with salt and pepper to taste.
Step 4: Combine Ingredients
Add the sautéed vegetable mixture, chopped cooked chicken, sun-dried tomatoes, and crumbled feta cheese to the egg mixture. Gently fold everything together until evenly combined.
Step 5: Fill the Muffin Tin
Spray a muffin tin with cooking spray or lightly grease with avocado oil. Pour the egg mixture into each muffin cup, filling them about ¾ of the way full.
Step 6: Bake
Place the muffin tin in the preheated oven and bake for 20-25 minutes or until the egg cups are set and lightly golden on top. A toothpick inserted in the center should come out clean.
Step 7: Cool and Serve
Once baked, remove the muffin tin from the oven and let it cool for a few minutes. Carefully run a spatula around the edges of each cup to release them from the tin. Serve warm or allow to cool completely before storing.
Dietary Swaps & Alternatives

- Vegetarian Option: Substitute the chicken with cooked quinoa or black beans for a hearty vegetarian option.
- Cheese Alternatives: Use dairy-free cheese if you prefer a dairy-free version.
- Egg Substitute: For a vegan option, replace eggs with a mixture of silken tofu and nutritional yeast.
- Other Veggies: Feel free to add in other vegetables such as zucchini, mushrooms, or broccoli for added nutrition.
Frequent Missteps to Avoid
When making Chicken and Spinach Egg Cups, here are a few common pitfalls to avoid:
- Overfilling the muffin cups: Leave enough space for the egg mixture to rise while baking.
- Not greasing the muffin tin: This could lead to a messy and frustrating cleanup.
- Skipping the sautéing step: Sautéing the vegetables enhances their flavor and prevents excess moisture in the egg cups.
- Removing too soon from the oven: Ensure the egg cups are fully set before taking them out to avoid a soggy center.
Save It for Later

- Reheat in the microwave for about 30 seconds to 1 minute, or until heated through.
