One-Pan Ham Swiss Frittata (Printable Version)

Ham, Swiss cheese, and veggies are baked together in a single pan for a savory, speedy meal.

# What You'll Need:

→ Eggs & Dairy

01 - 8 large eggs
02 - 1/4 cup whole milk
03 - 1 cup shredded Swiss cheese

→ Meats

04 - 1 cup diced cooked ham

→ Vegetables

05 - 1/2 cup diced yellow onion
06 - 1 cup chopped baby spinach
07 - 1/2 cup cherry tomatoes, halved

→ Spices & Seasonings

08 - 1/2 teaspoon salt
09 - 1/4 teaspoon black pepper
10 - 1/4 teaspoon dried thyme

→ For Cooking

11 - 1 tablespoon olive oil

# How To Make:

01 - Set the oven temperature to 375°F (190°C) and allow it to preheat.
02 - Heat olive oil in a large oven-safe skillet over medium heat. Add diced onion and sauté for 3 minutes until translucent.
03 - Stir in diced ham and cook for 2 minutes. Add chopped spinach and halved cherry tomatoes; cook until spinach wilts, about 1 minute.
04 - In a mixing bowl, whisk together eggs, milk, salt, pepper, and dried thyme. Incorporate half of the shredded Swiss cheese.
05 - Pour the egg mixture evenly over the ham and vegetables in the skillet. Sprinkle the remaining Swiss cheese on top.
06 - Cook the mixture on the stovetop for 2–3 minutes until the edges begin to set.
07 - Transfer the skillet to the preheated oven. Bake for 12–15 minutes, or until the center is set and the frittata is puffed.
08 - Remove skillet from the oven, allow to cool briefly, then slice and serve warm or at room temperature.

# Helpful Hints:

01 -
  • You can toss in whatever veggies are left and it still feels like a treat.
  • The frittata slices cleanly and tastes delicious cold, so meal prep is a breeze.
02 -
  • Skip pre-shredded cheese—once, my frittata turned oddly rubbery until I switched to hand-shredded Swiss.
  • Pat the ham dry if it’s too moist, or you'll end up with watery eggs.
03 -
  • Use a well-oiled skillet and let the edges set before baking to avoid sticking.
  • For maximum fluffiness, don’t skimp on whisking the eggs—a little extra air makes the frittata lighter.
