Directions

  1. Heat the oven and whisk the base

    Place a rack in the center and heat the oven to 375°F. Whisk the eggs, cottage cheese, cheddar, 1/4 teaspoon salt, black pepper and smoked paprika in a large bowl until the yolks are fully blended; small cottage-cheese curds are expected.

  2. Soften the vegetables

    Heat the olive oil in a well-seasoned 10-inch cast-iron or oven-safe nonstick skillet over medium. Add the onion, green pepper and remaining 1/4 teaspoon salt. Cook for 6 to 8 minutes, stirring occasionally, until the onion is translucent and the pepper is tender with a few browned edges.

  3. Arrange the tomatoes

    Reduce the heat to medium-low. Stir in half the parsley, then spread the vegetables evenly across the skillet. Arrange the tomato halves cut-side up so they remain visible in the finished frittata.

  4. Set the edges gently

    Pour in the egg mixture and stir once from the center to distribute the vegetables without scraping the pan. Cook undisturbed for 2 minutes, just until a narrow ring begins to set around the edge; the center should still be liquid.

  5. Bake to a tender set

    Transfer the skillet to the oven and bake for 14 to 18 minutes, until the center no longer ripples and an instant-read thermometer inserted in the middle reaches 160°F. Avoid baking beyond 170°F, which can squeeze moisture from the cottage cheese and toughen the eggs.

  6. Rest, slice and serve

    Set the hot skillet on a heatproof surface and rest for 5 minutes; keep the handle covered because it remains hot. Run a thin spatula around the edge, cut into six wedges and finish with the remaining parsley.

Why this works

Why it worksCottage cheese adds protein and moisture without leaving a heavy layer; whisking it directly into the eggs distributes its curds through every slice.
Why it worksCooking the onion and green pepper before adding eggs drives off water and prevents a wet center, while tomatoes stay on top where their juice can evaporate.
Why it worksA brief stovetop set followed by moderate oven heat cooks the center evenly without scorching the bottom or turning the outer eggs rubbery.

Swaps & notes

Easy swaps

  • Use red or yellow bell pepper in place of green pepper. Keep the quantity to one medium pepper so the vegetables do not overwhelm the egg structure.
  • Replace cheddar with crumbled feta, Monterey Jack or a low-moisture mozzarella. Avoid fresh mozzarella unless it is thoroughly drained and patted dry.
  • For a dairy-free version, omit cottage cheese and cheddar and whisk in 1/2 cup unsweetened soy milk; the frittata will be lighter and provide less protein.

Cook notes

  • Full-fat small-curd cottage cheese gives the smoothest, least watery result. If liquid has pooled in the container, spoon off the excess before measuring.
  • The total time includes the 5-minute rest, which makes cleaner wedges and lets carryover heat finish the center.
  • The licensed photograph clearly shows a golden frittata wedge with tomato and green pepper embedded on top; the recipe matches that finished form, visible vegetables and simple plated presentation.

Storage

Cool within 2 hours, cut into wedges and refrigerate in a shallow airtight container for up to 4 days. Reheat one wedge covered in the microwave at 50% power for 60 to 90 seconds, or in a 325°F oven for 8 to 10 minutes, until it reaches 165°F. Freeze individually wrapped wedges for up to 2 months; thaw overnight before reheating.

Questions

Will cottage cheese make the frittata lumpy?

Small soft curds may remain, but they melt into the egg matrix as it bakes. Whisk thoroughly and use small-curd cottage cheese if you prefer the most uniform texture.

Can I make this frittata without a cast-iron skillet?

Yes. Sauté the vegetables in a regular skillet, transfer them to a greased 9-inch pie plate, add the egg mixture and bake for 20 to 24 minutes, checking for a 160°F center.

Why did my frittata release water?

The vegetables may have been undercooked, the cottage cheese may have contained excess whey, or the eggs may have been baked too hot. Soften the vegetables fully, drain pooled whey and stop baking at 160°F.
