Additions & Substitutions
Additions:
- Greens - You can use any combination of leafy greens or just one variety like only using spinach. I like using a combination of spinach, kale, and chard for this recipe. You can use frozen spinach; however, I prefer fresh.
- Bell Peppers - Any combination of bell peppers would change the flavor.
- Mushrooms - Add some sauteed mushrooms to the mix.
- Protein - Looking to add protein? Bacon, grilled chicken, sausage, or salami would all work nicely.
- Sun-dried tomatoes - These will add a nice tomato flavor.
Substitutions
- Cheese - If you don't like mozzarella cheese or feta cheese, you can substitute goat cheese, sharp cheddar, parmesan cheese, or any cheese of your choice. Block cheese works better than shredded cheese but, you can use shredded. Block cheese cut into pieces will give you a nice cheese bite.
- Spike Seasoning - Spike seasoning is easily bought in the spice section of your local grocery store. However, if you would rather substitute then consider using italian seasoning or fresh herbs like thyme, basil, dill or oregano.
- Eggs - You can use egg whites in this recipe or a combination of yolks and whites. I use large eggs in this recipe.
- Casserole Dish - You can easily make this recipe and pour the mixture into a muffin tin to bake. This will give you individual portions and is nice for company.
How To Make A Spinach Feta Egg Bake Recipe: Step-By-Step
Here are some quick visual instructions. Remember that full instructions with the exact ingredients are in the printable recipe card:
Step 1: Preheat the oven to 375 degrees. Spray a 9x13 baking dish with a non-stick cooking spray. Heat the olive oil in a large non-stick skillet over medium high heat. Add the greens. Use a spatula to turn the greens over until all of the greens are wilted. Place the greens into the bottom of the baking dish.
Step 2: Cut the mozzarella into cubes and place into a medium mixing bowl. Crumble the feta cheese and place it into the bowl. Sprinkle the green onions over the top of the cheese. Add the Spike seasoning and black pepper to the cheese. Combine and place over the top of the greens in the casserole.
Step 3: Beat the eggs until fully combined. Pour over the cheese. Use a spoon or fork to gently combine all layers.
Step 4: Bake 40-45 minutes until the mixture is completely set and the top is slightly brown.
Confidence Tip
Feel free to add more cheese! The cheesier the better.

We loved this! Added a bit of fresh sliced mushrooms and red bell pepper. Made it for Sunday breakfast and we had about half leftover. I cut it the leftovers into slices and put them into meal prep containers with cooked sausage patties. Reheated super well and lots of protein. Will definitely make again!
