There is something undeniably comforting about a warm breakfast casserole pulling fresh from the oven, filling the kitchen with the scent of oregano and toasted cheese. But if I’m being honest, traditional stratas—often loaded with heavy bread and cream—sometimes leave me feeling a bit sluggish by mid-morning. That was the spark for this recipe.
I wanted to capture that cozy, “Sunday brunch” feeling but flip the script on the ingredients. By swapping out the bread for nutty, protein-rich quinoa and loading up on garden-fresh vegetables, this dish transforms into something entirely different. It’s vibrant, colorful, and surprisingly light, yet it holds you over until lunch. I love serving this when friends come over because it looks beautiful on the table, and it caters to so many different dietary needs without making a fuss about it.

Why This Mediterranean Twist Works
If you are looking for fresh Mediterranean diet breakfast recipes that go beyond yogurt and fruit, this bake is a game-changer. The magic lies in the texture. Quinoa provides a lovely, subtle crunch that contrasts perfectly with the creamy egg and cottage cheese mixture. Unlike bread, which can get soggy, the quinoa maintains its integrity, absorbing the savory juices from the peppers and mushrooms without losing its bite.
The flavors here are distinct and bold. We aren’t just throwing raw veggies into eggs; we take the time to sauté the onions, peppers, and mushrooms with garlic first. This step releases their natural sweetness and ensures every bite is packed with flavor. The salty punch of reduced-fat feta cheese sprinkled on top finishes it off, giving you that classic savory profile that pairs so well with a hot cup of coffee.
Powering Up Without the Crash
One of the main reasons I keep coming back to this quinoa breakfast bake is how it makes me feel afterward. I’m always looking for meals that support steady energy levels rather than creating a spike and a crash. This recipe is naturally rich in fiber thanks to the spinach, peppers, and whole grains, and it packs a serious protein punch from the egg whites and cottage cheese.
For those navigating dietary goals, this is a wonderful, diabetes-friendly option when enjoyed as part of a balanced plan. The combination of complex carbohydrates and protein helps slow down digestion. Many readers have shared that they love prepping this on a Sunday to have a grab-and-go option that keeps them full and focused during busy work weeks. If you are interested in other ways to manage morning energy, you might find my thoughts on avoiding high morning blood sugar helpful as well.

Mastering the Layers
Learning how to make quinoa breakfast casserole isn’t complicated, but a little technique goes a long way. The key is the layering. I like to spread half the quinoa on the bottom of the dish to create a sturdy base. Then, I layer the sautéed veggie mixture and dollops of cottage cheese before repeating the process.
This method ensures that every slice has an equal distribution of “the good stuff.” You won’t end up with one slice that is all egg and another that is all spinach. It also helps the bake cook evenly. Once you pour the egg mixture over the top, give the dish a little jiggle to let the liquid settle into the nooks and crannies of the quinoa. It’s a small step, but it makes a difference in the final texture.
If you find yourself with extra quinoa after prepping this, don’t let it go to waste! You can easily use it up in a Mediterranean Quinoa Salad for lunch later in the week.

Customize Your Savory Bake
The beauty of this savory quinoa vegetable breakfast bake is its versatility. While I love the bell pepper and mushroom combo, you can absolutely clear out your crisper drawer with this recipe. Have some leftover roasted asparagus or broccoli? Chop it up and toss it in. Prefer a sharper cheese? Swap the feta for goat cheese or a sprinkle of Parmesan.
For a bit more heat, I sometimes increase the red pepper flakes or add a dash of hot sauce to the egg mixture. If you are a fan of savory breakfasts, you might also enjoy trying Sunrise Baked Feta Eggs, which offers a similar flavor profile but with a different texture.
This dish is resilient. As long as you keep the ratio of eggs to dry ingredients roughly the same, you can experiment with flavors that suit your family’s palate. It stores beautifully in the fridge, making it a reliable staple for meal prep.

1 red bell pepper, stemmed, seeded, and chopped
1 green bell pepper, stemmed, seeded, and chopped
1 cup fresh baby spinach, roughly chopped and packed
1 medium zucchini, chopped
Dairy & Eggs
4 large eggs
1 cup liquid egg whites (approx. 8 whites)
1 cup skim milk (or unsweetened almond milk)
3/4 cup no-salt-added 1% cottage cheese, divided
1/4 cup crumbled reduced-fat feta cheese
Pantry & Grains
2 cups cooked quinoa (white or tricolor)
1 Tbsp olive oil
1 tsp dried oregano
1/2 tsp freshly ground black pepper
1/4 tsp salt (optional, adjust to taste)
1/4 tsp crushed red pepper flakes (optional)
Non-stick cooking spray
Instructions
- Preheat your oven to 350°F (175°C). Generously grease a 9×13-inch baking dish with non-stick cooking spray and set aside.
- In a large skillet, heat the olive oil over medium heat. Once shimmering, add the onion, dried oregano, black pepper, salt, and red pepper flakes (if using). Sauté for 6 to 8 minutes, stirring occasionally, until the onions are soft.
- Stir in the minced garlic and cook for 30 seconds until fragrant. Add the mushrooms, red bell pepper, green bell pepper, and zucchini. Cook for another 5 minutes, stirring occasionally, until the vegetables are tender-crisp.
- Remove from heat. Stir in the spinach, basil, and parsley, tossing gently until the spinach just begins to wilt (about 1 minute).
- In a large mixing bowl, whisk together the whole eggs, liquid egg whites, and milk until frothy and well combined.
- Spread 1 cup of the cooked quinoa evenly across the bottom of the prepared baking dish. Top with half of the vegetable mixture, followed by half of the cottage cheese.
- Layer the remaining quinoa and vegetable mixture on top. Dollop the remaining cottage cheese over the vegetables.
- Pour the egg mixture evenly over the entire casserole. Sprinkle the crumbled feta cheese on top.
- Bake for 40 to 45 minutes, or until the eggs are set and the center is firm. Let the casserole rest for 5 to 10 minutes before slicing. Garnish with extra fresh basil if desired.
