Ingredient Notes

Ingredients for the frittata muffins individually portioned out on a counter.
  • Olive oil: Use a little oil or butter to gently cook the veggies.
  • Shredded zucchini: It’s important to grate the zucchini and wring out as much of the liquid as possible.
  • Frozen spinach: Use either thawed spinach or finely chopped cooked spinach.
  • Whole eggs: You only need 3 eggs to bind the mixture together.
  • Flour: Use either whole wheat, white whole wheat or gluten-free flour to absorb the extra liquid in these breakfast muffins.
  • Onion powder: This is optional, but it adds a savory flavor that pairs really well with the different veggies.
  • Cheddar cheese: Use grated yellow or white cheddar. Feel free to use your favorite cheese instead.
  • Salt: This will highlight the flavors in these spinach egg muffins, but it’s not recommended if you’re serving them to babies.

Step-by-Step Instructions

  1. Preheat to oven 350 degrees F.
  2. Heat the oil in a frying pan over medium heat. Add the zucchini and spinach and fry lightly for 3-4 minutes until the vegetables are soft.
  3. In a large bowl, mix the eggs, cheese (if using), flour and spices together. Add the cooked vegetables and mix until well combined.
  4. Divide the egg mixture between 10-12 silicone baking cups or use a regular muffin tin. Bake for 15-20 minutes or until egg has solidified.
  5. Remove from the oven and allow the frittata muffins to cool. Serve warm or store in the fridge for later.

RECIPE TIPS

  • I used a heart shaped silicone muffin pan for this recipe, but you can use regular silicone baking cups (the egg cups pop right out) or grease a muffin tin really well.
  • Frozen spinach that’s been squeezed of excess moisture is really convenient for this recipe since it’s already finely chopped. You can either use small spinach nuggets if you can find them or defrost a block of chopped frozen spinach and measure out the quantity required for the recipe.
  • If making this recipe for baby-led weaning, you may wish to leave out the salt to limit baby’s sodium consumption, especially before the age of one. However, if you’re making the frittata muffins for older children or adults, you might want to add it to incorporate some extra flavor.

Recipe FAQs

Can you make dairy-free mini frittatas?

Yes! The only dairy comes from the cheese, so you can easily substitute a dairy-free cheese or skip it. 

Why are my zucchini egg muffins falling apart?

The number one issue when baking with zucchini or spinach is the excess liquid. It’s very important to squeeze off as much of the excess water as possible. Otherwise, the eggs will not be able to hold the mixture together.

How long do zucchini egg muffins last in the freezer?

When properly stored, they’ll last up to three months. It’s important to use a thick container and remove as much air as possible to avoid freezer burn.

Storage Guidelines

  • Refrigerator: Cool the muffins to room temperature, then store the leftovers in an airtight container in the fridge for 4-5 days.
  • To freeze: You can also freeze the leftovers for up to 3 months. Just thaw them in the fridge overnight, then reheat by microwaving for 1 minute or baking in a toaster oven at 350 degrees F for 5-7 minutes.

Recipe Variations

  • Try a different cheese: This zucchini egg cups recipe would be delicious with feta cheese, Parmesan, or even smoked gouda.
  • Adjust the size: You can easily pour the mixture into regular muffin pans, or you can use a mini muffin pan for tiny bites. Just be sure to adjust the cooking time!
  • Add more veggies: The zucchini and spinach would also taste great with some sauteed white onion or red bell pepper. 
  • Extra protein: If you want even more protein, you can substitute egg whites. This is best for older kids or adults, as babies and young children need the extra healthy fats.
