Ingredients You'll Need

All the ingredients here are simple and accessible, yet each one adds its own unique touch to this dish’s flavor, texture, and appearance. From the smoothness of the cottage cheese to the bright freshness of the veggies, you’re getting a balanced and vibrant meal in every bite.

• Olive oil or cooking spray: helps keep the casserole from sticking and adds a subtle, fruity richness.
• Medium eggs: the main structure of the casserole, binding everything with fluffy protein.
• Cottage cheese: adds creaminess and moisture plus extra protein without heaviness.
• Thick Greek yogurt: keeps the texture luxuriously tender while contributing to protein content.
• Red bell pepper: brings a sweet crunch and refreshing color contrast.
• Scallions: add a mild oniony flavor that livens up the dish without overpowering it.
• Baby spinach: packs nutrients and blends beautifully into the egg mixture.
• Salt and freshly ground black pepper: essential seasonings that enhance all the flavors.

Directions

Step 1: Preheat your oven to 375°F (190°C). Lightly grease a 9 × 13-inch baking dish — or if you prefer taller, chunkier slices, use a 9 × 9-inch pan instead. I usually use a quick spray of olive oil or a mist of cooking spray to keep the casserole from sticking while adding a touch of flavor.

Step 2: Crack 12 medium eggs into a large mixing bowl and whisk them until they’re completely smooth. Then spoon in 1 ½ cups of cottage cheese and ½ cup of thick Greek yogurt, whisking again. Don’t worry if some curds of cottage cheese remain; they add to the casserole’s lovely, rustic texture.

Step 3: Stir in the diced red bell pepper, diced scallions, and roughly shredded baby spinach. Sprinkle in ½ teaspoon of salt and ¼ teaspoon of freshly ground black pepper. Give everything one last good whisk to make sure the ingredients are evenly distributed throughout the mixture.

Step 4: Pour the well-mixed egg and veggie mixture into your prepared baking dish. Smooth out the top lightly if needed.

Step 5: Bake the casserole on the middle rack of your preheated oven for 35 to 40 minutes. You’ll know it’s done when the center is fully set (no jiggle) and the top has a beautiful golden hue.

Step 6: Remove the casserole from the oven and let it rest for about 10 minutes before cutting it into squares. This resting time helps the casserole settle so it slices neatly and holds its shape when served.

Servings and Timing

This High Protein Breakfast Casserole with Cottage Cheese and Veggies Recipe yields about 6 generous servings, making it awesome for feeding a small family or meal prepping for several days. The prep time is just 5 minutes, thanks to how quickly you can combine the ingredients. Baking takes about 35 minutes, so your total time from start to table clocks in around 40 minutes. Be sure to factor in the 10-minute resting time before slicing — it’s worth the wait to get perfect squares.

How to Serve This High Protein Breakfast Casserole with Cottage Cheese and Veggies Recipe

I love serving this casserole warm, straight from the oven with a sprinkle of fresh herbs like parsley or chives to add a fresh pop of green and flavor. It pairs beautifully with a crisp side salad or some fresh fruit for a balanced breakfast or brunch experience. If I’m serving it for a larger gathering, I like to arrange the squares on a wooden board, letting people help themselves.

For a finishing touch, sprinkling a little grated Parmesan or a handful of crumbled feta on top before baking can add a nice salty note that complements the veggies perfectly. When it comes to drinks, I often reach for a sparkling water with a twist of lemon or a cup of freshly brewed coffee. On weekends, a light mimosa or glass of chilled white wine can elevate the occasion wonderfully.

This casserole is also a brilliant option for brunch gatherings, lazy weekend breakfasts, or even a make-ahead weekday meal. It holds up well at room temperature, meaning you can prepare it in advance and serve it buffet-style with minimal stress. Plus, the slices are great for portion control—just enough to keep you full and satisfied without feeling weighed down.

Variations

One of my favorite things about this High Protein Breakfast Casserole with Cottage Cheese and Veggies Recipe is how versatile it is. If you want to switch things up, try swapping the bell pepper for diced zucchini or mushrooms for a different veggie twist. You can also add cooked bacon, sausage, or diced ham if you want more savory depth or extra protein. For a dairy-free alternative, try using a plant-based yogurt and soft tofu instead of cottage cheese and Greek yogurt — it won’t be quite the same texture but still delivers the creamy factor.

For those who need a gluten-free breakfast, this recipe is naturally so since it contains no wheat or grains, making it safe and friendly. If you’re looking for a vegan version, I recommend blending silken tofu with nutritional yeast, black salt (kala namak), and a pinch of turmeric to mimic eggs, then adding your favorite veggies to bake a similar casserole.

Another idea I’ve had fun with is adding different herbs and spices. A pinch of smoked paprika or some fresh thyme brightens the flavor, and a bit of shredded cheese on top makes a delicious golden crust. If you want to speed up prep, you can mix everything the night before and bake in the morning, or bake mini portions in muffin tins for perfectly portioned breakfast bites.

Storage and Reheating

Storing Leftovers

Leftover casserole should be allowed to cool completely before storing. I transfer the squares into an airtight container, layering them with parchment paper to prevent sticking, and keep refrigerated for up to 3 days. This way, the flavors stay fresh and the texture remains inviting.

Freezing

You can absolutely freeze this casserole! To do so, I slice it into individual portions and wrap each piece tightly in plastic wrap followed by foil or place them in a freezer-safe container. It keeps well in the freezer for up to 2 months. When you’re ready to enjoy it, thaw overnight in the fridge for best results.

Reheating

To reheat, I prefer using the oven or toaster oven at 350°F (175°C) for about 10–15 minutes until warmed through. This method helps the casserole regain a bit of its fresh-baked texture and prevents it from getting soggy. If you’re in a hurry, microwaving works too, but I recommend reheating in short intervals to avoid drying it out or making it rubbery.

FAQs

Can I make this casserole ahead of time?

Absolutely! You can mix all the ingredients the night before and keep the mixture covered in the fridge. When you’re ready, just pour it into the baking dish and bake as directed. This saves time in the morning and lets the flavors meld beautifully.

Is this recipe suitable for meal prep?

Yes, this casserole is fantastic for meal prep. It stores well in the fridge and freezes beautifully, making it easy to portion out multiple balanced breakfasts or snacks throughout the week.

Can I add other vegetables or proteins?

Definitely! Feel free to customize with your favorite veggies like mushrooms, zucchini, or kale. Adding cooked bacon, sausage, or even smoked salmon can boost the protein content and flavor in delightful ways.

What can I use if I don’t have cottage cheese?

If you don’t have cottage cheese, you can substitute with ricotta or extra thick Greek yogurt. Both provide creaminess and richness that complement the eggs and veggies well.

How do I know when the casserole is fully cooked?

The casserole is done when the center is fully set and no longer jiggles when you gently shake the pan. The top should be golden brown, and a toothpick inserted in the middle should come out clean or with just a few moist crumbs.
