Reasons to try it:

If you want a complete dinner, this casserole pairs well with simple roasted or baked fish — try it alongside a buttery, herb-baked salmon for an elegant weeknight upgrade: baked Boursin salmon.
How this recipe comes together
This is a one-dish assembly recipe. First, the raw vegetables are tossed with cottage cheese to add creaminess and body. A seasoned egg-olive oil mixture is whisked and folded through that veggie base; eggs set the casserole so it slices cleanly after baking. The casserole is spread in a greased 9×9 dish, topped with a little mozzarella for color and melt, then baked at 375°F until golden and set. Total hands-on time is about 10–15 minutes; bake time 30–35 minutes.
What you’ll need
- 1 cup cottage cheese (small-curd preferred for texture; ricotta works as a substitute)
- 1 cup broccoli florets, chopped
- 1 cup bell pepper, diced
- 1 cup zucchini, sliced
- 1 cup cherry tomatoes, halved
- 1/2 cup spinach, chopped
- 1/2 cup red onion, finely chopped
- 1/4 cup shredded mozzarella cheese
- 2 eggs
- 1 tablespoon olive oil (plus more for greasing if not using cooking spray)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt
- 1/4 teaspoon dried oregano
- Cooking spray or olive oil for greasing the baking dish
Ingredient notes:
- If your cottage cheese is very wet, drain a little in a fine sieve to avoid excess moisture.
- Use fresh vegetables when possible; frozen broccoli or bell pepper can be used but pat dry after thawing.
- Swap mozzarella for cheddar or a sprinkle of Parmesan for a sharper finish.
Step-by-step instructions
- Preheat the oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish with cooking spray or olive oil.
- In a large bowl, combine the cottage cheese, broccoli, bell pepper, zucchini, cherry tomatoes, spinach, and red onion. Toss gently so the vegetables are coated.
- In a separate bowl, whisk together the eggs, 1 tablespoon olive oil, garlic powder, onion powder, black pepper, salt, and dried oregano until smooth.
- Pour the egg mixture over the vegetable-cottage cheese mix. Stir until everything is evenly combined.
- Transfer the mixture to the prepared baking dish and spread into an even layer. Smooth the top with a spatula.
- Sprinkle the shredded mozzarella evenly over the top.
- Bake for 30–35 minutes, until the top is golden and the center is set. A knife inserted near the center should come out mostly clean, or the internal temperature should reach about 160°F (71°C).
- Remove from the oven and cool for 5–10 minutes before slicing. Serve warm.
Best ways to enjoy it
- Serve in wedges with a crisp green salad and a drizzle of balsamic vinaigrette.
- Offer crusty bread or a grain side (quinoa, brown rice) to make it more filling.
- Turn it into a brunch spread alongside smoked salmon or pan-seared fish; it’s particularly tasty with garlicky spinach and mozzarella-style salmon: baked salmon with garlicky spinach and mozzarella.
- Top slices with a spoonful of salsa or pesto for extra brightness.
Storage and reheating tips
- Refrigerator: Store leftovers in an airtight container for 3–4 days.
- Freezer: Wrap tightly or use freezer-safe containers and freeze for up to 2–3 months. Thaw overnight in the fridge before reheating.
- Reheat: Warm individual portions in the microwave for 60–90 seconds, or reheat a whole dish in a 350°F (175°C) oven for 15–20 minutes until heated through. Cover with foil to prevent over-browning.
Food safety: because this dish contains eggs and dairy, keep it refrigerated within two hours of baking and reheat to at least 165°F (74°C) when serving from the fridge or freezer.
Pro chef tips
- Size veggies uniformly so everything cooks evenly — smaller broccoli florets and thin zucchini slices help.
- If your tomatoes are very juicy, remove seeds or pat halves dry to avoid watery casserole.
- For a firmer texture, let the casserole rest longer after baking (10–15 minutes) — it will set and slice cleaner.
- Use room-temperature eggs for smoother incorporation.
- Add a teaspoon of Dijon mustard to the egg mix for a subtle depth of flavor.
Creative twists
- Mediterranean: Replace mozzarella with feta, add chopped Kalamata olives and a tablespoon of lemon zest.
- Cheesy: Stir 1/2 cup grated sharp cheddar into the base and top with extra cheese for a richer bake.
- Protein boost: Fold in 1 cup shredded rotisserie chicken or cooked crumbled turkey.
- Vegan option: Use silken tofu blended with a tablespoon of ground flaxseed and nutritional yeast for the egg substitute, and swap cottage cheese for a thick cashew cream. Bake until set — results will differ but still tasty.
- Spicy: Add 1/4 teaspoon red pepper flakes or a diced jalapeño to the vegetable mix.
Common questions
Q: Can I make this ahead and bake later?
A: Yes. Assemble the casserole in the greased dish, cover tightly, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time if baking straight from cold.
Q: Can I substitute ricotta for cottage cheese?
A: Absolutely. Ricotta gives a smoother, slightly milder texture. If using ricotta, the same quantity works fine.
Q: Will the vegetables become soggy?
A: If you use very watery tomatoes or thawed frozen vegetables, excess moisture can accumulate. Pat watery ingredients dry, remove tomato seeds, or slightly under-slice zucchini to reduce released liquid. Let the casserole rest after baking to firm up.
Q: Is this casserole freezer-friendly?
A: Yes — it freezes well for 2–3 months. Thaw overnight in the fridge and reheat in a 350°F oven until warmed through.
Q: How do I know when it’s done?
A: The top should be lightly golden and the center set. A knife inserted near the middle should come out mostly clean. For precision, an internal temperature of about 160°F (71°C) is a safe target for egg-based bakes.
