Simple Cottage Cheese Frittata

The way those cherry tomatoes burst open in the oven, their juices mingling with pockets of melted cottage cheese, still catches me off guard every time I pull this frittata from the oven. My sister originally sent me the recipe during a period when she was obsessed with finding protein-packed breakfasts that didn't feel like a chore to eat, and somewhere along the way it became my Sunday morning default regardless of the season.

Last winter I made this for friends who had just moved into their first apartment together, serving it straight from the skillet on their makeshift coffee table while we sat cross-legged on the floor. They still text me about that meal whenever they spot cottage cheese on sale at the grocery store.

Ingredients

• 6 large eggs: Room temperature eggs whisk up more easily and create a fluffier texture in the final bake
• 1 cup cottage cheese: Small curd cottage cheese distributes more evenly throughout the mixture than large curd varieties
• 1/4 cup milk: Whole milk creates the richest result but any milk you have will work perfectly fine
• 1/2 cup shredded cheddar or Swiss cheese: Sharp cheddar adds a bold punch while Swiss brings a nutty mellow flavor
• 1 cup baby spinach: Roughly chop the spinach so it distributes evenly rather than clustering in one section
• 1/2 cup cherry tomatoes: Halving them allows their juices to release and create little bursts of flavor
• 1/4 cup green onions: Both the white and green parts add different layers of mild onion flavor
• 2 tablespoons fresh parsley or chives: Fresh herbs make a noticeable difference compared to dried here
• 1/2 teaspoon salt: The cottage cheese already contains salt so taste before adding more
• 1/4 teaspoon freshly ground black pepper: Freshly ground has more complexity than pre-ground pepper
• 1/4 teaspoon dried oregano: Optional but adds a lovely Italian undertone that complements the tomatoes
• 1 tablespoon olive oil or butter: Butter creates a richer flavor while olive oil keeps things lighter

Instructions

Get your oven ready:

Preheat oven to 375°F (190°C) and grease a 9-inch ovenproof skillet or pie dish with your olive oil or butter.

Whisk the base:

In a large bowl, whisk together eggs, cottage cheese, milk, salt, pepper, and oregano until the mixture is completely smooth and uniform.

Add the mix-ins:

Stir in the shredded cheese, chopped spinach, cherry tomatoes, green onions, and fresh herbs until everything is evenly distributed.

Assemble and bake:

Pour the mixture into your prepared skillet, spread everything evenly, and bake for 20-25 minutes until puffed and golden with just a slight wobble in the center.

Rest before serving:

Let the frittata cool for 5 minutes so it sets properly, then slice and serve warm or at room temperature.

Pin It

My neighbor started making this every week after she tasted it at a brunch I hosted, and now she keeps a printed copy taped inside her kitchen cabinet door. It is become the kind of recipe that feels like sharing a secret rather than just exchanging cooking instructions.

Make It Your Own

The beauty of this frittata is how forgiving it is with substitutions. I have used kale instead of spinach, added sautéed mushrooms in autumn, and thrown in diced bell peppers when I needed color for a brunch spread.

Serving Suggestions

A simple green salad with lemon vinaigrette cuts through the richness beautifully. Crusty bread for soaking up any juices turns it from a light meal into something more substantial.

Storage and Reheating

The frittata keeps remarkably well in the refrigerator for up to four days. I often make it on Sunday and eat slices throughout the week for quick breakfasts or lunches.

• Reheat individual slices in the microwave for 45-60 seconds
• Cold frittata makes an excellent sandwich filling with some arugula
• Freeze wrapped slices for up to two months if you want to meal prep

There is something deeply satisfying about a dish that looks elegant but comes together with such humble ingredients. This frittata has saved more last-minute meals and impromptu gatherings than I can count.

Recipe Questions

Absolutely, by using plant-based cheese and milk alternatives, you can keep it dairy-free and still enjoy the rich texture.
