This crustless cottage cheese frittata is one of my favorite ways to start the day! Each slice is light, fluffy, and delivers about 15 grams of protein, thanks to the mix of eggs, egg whites, and cottage cheese (triple protein-threat, lol!). Plus, it’s loaded with fresh veggies – what could be better?

And while it makes a delicious, high-protein breakfast, this frittata is just as tasty for lunch or dinner. Pair it with a simple kale salad and some perfectly roasted potatoes for a balanced, satisfying meal.

💡 PRO TIP: Cottage cheese is a simple (and delicious!) way to boost your protein intake. Just ½ cup delivers 14 grams of protein, making it a powerhouse ingredient for everyday meals. I love sneaking it into recipes like myprotein-packed cottage cheese bagels, and creamy blender alfredo sauce. It’s such an easy—and tasty—way to level up the protein in your favorite dishes!

That’s the beauty of a frittata: it’s flexible, forgiving, and always delicious! I love making this version at the end of summer when my Jersey garden is overflowing with tomatoes and zucchini. But here is some more seasonal inspiration:

Summer: Keep as-is or use bell peppers, corn, or spinach for a different spin on this recipe.
Fall: Add mushrooms, roasted butternut squash, or kale for something heartier and more comforting.
Winter: Go with broccoli, cauliflower, or sun-dried tomatoes for rich, cozy flavors.
Spring: Try asparagus, peas, and fresh herbs like dill or parsley for a bright, fresh flavor.

💡 Pro Tip: Whatever veggies you choose, be sure to measure out 4 cups! When I was testing this recipe, I found this was the perfect ratio to create a filling, nutrient-rich frittata that feels light yet satisfying.
