Why I Love This Recipe
What makes this recipe such a winner is how balanced it is. You get tender broccoli, sweet bell peppers, zucchini, and spinach all tucked into a creamy, savory cheese mixture that feels hearty without being heavy. Cottage cheese adds a protein boost and creates a soft, rich texture that works perfectly in baked dishes like this.
I also love how flexible it is. You can serve it as a vegetarian main dish, use it as a protein-packed breakfast bake, or pair it with other simple meals for a bigger spread. It’s practical, reliable, and one of those recipes that makes healthy eating feel easy rather than complicated.
Ingredients
- 2 cups broccoli florets
- 1 cup chopped bell peppers, mixed red and yellow
- 1 cup diced zucchini
- 1 cup baby spinach
- 1 cup cottage cheese
- 2 large eggs
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried oregano
- 1/2 teaspoon dried basil
- Cooking spray or olive oil, for greasing
Swaps and Notes
This recipe is wonderfully adaptable, which is one reason it works so well for real life cooking. If you don’t have zucchini, try chopped mushrooms or cauliflower. If you want even more greens, add kale in place of some of the spinach. You can also use orange or green bell peppers depending on what you have on hand.
For the cheese, full-fat or low-fat cottage cheese both work well. If you prefer a smoother texture, blend the cottage cheese before mixing it in. Mozzarella gives the bake that classic stretchy, melty finish, while Parmesan adds a salty, nutty flavor that keeps everything tasting robust.
You can also add a pinch of red pepper flakes if your family likes a little heat.
How to Make High-Protein Veggie Bake with Cottage Cheese
- Preheat your oven to 375°F and lightly grease a baking dish with cooking spray or olive oil.
- Steam or lightly blanch the broccoli for 2 to 3 minutes so it begins to soften. Drain well.
- In a large mixing bowl, whisk together the cottage cheese and eggs until mostly smooth.
- Stir in the mozzarella, Parmesan, garlic powder, onion powder, salt, black pepper, oregano, and basil.
- Fold in the broccoli, chopped bell peppers, diced zucchini, and baby spinach. Mix until the vegetables are evenly coated.
- Transfer the mixture to the prepared baking dish and spread it into an even layer.
- Bake for 30 to 35 minutes, or until the center is set and the top is lightly golden.
- Let it rest for 5 to 10 minutes before slicing and serving.
The resting time helps the bake firm up, which makes it much easier to cut into neat portions.
Tips for Success
The biggest key to a great veggie bake is controlling moisture. Since vegetables naturally release water while baking, it helps to lightly cook the broccoli first and avoid overloading the dish with extra-wet ingredients. If your zucchini seems especially watery, pat it dry after dicing.
Another helpful tip is to chop the vegetables into similar-sized pieces. This helps everything cook evenly and ensures every bite has a balanced mix of textures and flavors.
For a more golden top, you can sprinkle a little extra mozzarella or Parmesan over the bake before it goes into the oven. And if you’re meal prepping, this dish holds together even better after it cools slightly.

Storage and Leftover Tips
Leftovers are one of the best parts of this recipe. Once cooled, store the veggie bake in an airtight container in the refrigerator for up to 4 days. Reheat individual slices in the microwave or warm larger portions in the oven until heated through.
You can also make it ahead and refrigerate it before baking. Just assemble everything, cover tightly, and bake when ready. If baking straight from the fridge, add a few extra minutes to the cooking time.
This recipe is also great for meal prep because the flavors settle in nicely overnight. A leftover slice makes a fantastic quick lunch or even a savory breakfast.
