How to Make These Frittata Cups

Start your morning with these easy veggie-loaded frittata cups that come together in just a few simple steps.

Sauté the vegetables in a skillet with olive oil over medium heat until they’re softened, then stir in the kale just until wilted. Remove from heat and let cool slightly.

Whisk the eggs in a large bowl with the egg whites, nutritional yeast, and seasonings until smooth and well combined.

Pour the egg mixture evenly into the muffin tin, filling each cup about three-quarters full, then add a scoop of veggies to each and gently mix. Bake until puffed and set in the center, then let cool for a few minutes before removing.

Enjoy warm on their own, or pair with sliced avocado, hot sauce, or fresh herbs for extra flavor.

For a savory side, pair these frittata cups with Chicken Apple Breakfast Sausage Patties for a full, protein-packed meal.

Tips & Troubleshooting

• Avoid sticking: Using a silicone muffin tray will help the frittata cups release easily. You can also use silicon or paper muffin liners.
• Prevent soggy cups: Lightly sauté the vegetables first to cook off excess moisture before adding them to the eggs.
• Get fluffy texture: Don’t overmix the eggs; whisk just until smooth and airy.
• Check for doneness: The centers should be just set and slightly springy when touched.
• Easy cleanup: Let the cups cool for a few minutes before removing to prevent tearing or crumbling.

Flavor Variations to Try

• Mediterranean: Kale, sun-dried tomatoes, olives, and dairy-free feta
• Southwest: Bell pepper, onion, jalapeño, black beans, and cilantro
• Mushroom & Herb: Sautéed mushrooms, kale, and fresh thyme
• Smoked Salmon: Chopped smoked salmon, chives, and dairy-free cream cheese
• Italian: Zucchini, cherry tomatoes, and basil

Storage & Meal Prep

Store your frittata cups in an airtight container in the fridge for up to 4 days.

Reheat in the microwave for about 30 to 40 seconds or in the oven at 325°F until warmed through.

For longer storage, let them cool completely, then freeze in a single layer before transferring to a freezer-safe bag or container. They’ll keep well for up to 1 month. Thaw overnight in the fridge and reheat before serving.

For best texture, avoid overcooking during the initial bake so they stay light and tender when reheated.
