04 - 1/4 cup grated Parmesan cheese

→ Meats

05 - 1 cup diced cooked ham

06 - 1 cup baby spinach, chopped

10 - 1/4 teaspoon black pepper
11 - 1/4 teaspoon garlic powder
12 - 1 tablespoon fresh chives, chopped

# Directions:

01 - Preheat oven to 375°F (190°C).
02 - In a large bowl, whisk together eggs, milk, salt, pepper, and garlic powder until well combined.
03 - Stir in cheddar cheese and Parmesan into the egg mixture.
04 - Heat olive oil in an oven-safe, nonstick skillet (10–12 inch) over medium heat. Add red onion and sauté for 2–3 minutes until softened.
05 - Add diced ham, chopped spinach, and cherry tomatoes. Cook for another 2–3 minutes, stirring occasionally.
06 - Pour the egg mixture evenly over the ham and vegetables in the skillet. Use a spatula to gently distribute the filling.
07 - Cook on the stovetop for 2–3 minutes, until the edges just begin to set.
08 - Transfer skillet to the preheated oven. Bake for 15–18 minutes, or until the center is just set and the top is lightly golden.
09 - Remove from oven and let cool for 5 minutes before slicing. Garnish with fresh chives if desired.
10 - Slice into wedges and serve, or cool completely for meal prep and refrigerate in airtight containers.

# Expert Tips:

01 -
  • It comes together in under 40 minutes, meaning you can go from hungry to fed before your coffee gets cold.
  • One skillet means minimal cleanup, which matters when you're already running late for work.
  • Leftovers stay fresh for days and taste just as good cold, making it the meal-prep hero breakfast deserves.
02 -
  • Don't skip the stovetop cooking time before the oven—those 2 to 3 minutes set the bottom and prevent a soggy base that makes the whole thing feel undercooked.
  • If your skillet isn't oven-safe, no shame in transferring everything to a baking dish once the bottom begins to set; frittatas are forgiving about the vessel as long as you finish them in the oven.
03 -
  • Invest in a quality nonstick skillet if you cook eggs regularly; it's one of those tools that quietly makes cooking easier every single time.
  • Room-temperature eggs whisk more smoothly and incorporate air better, creating a fluffier finished frittata than straight-from-the-fridge eggs.
