High Protein Cottage Cheese Egg Bake with Spinach
This high protein cottage cheese egg bake combines whole eggs, cottage cheese, spinach, and red pepper in a sliceable breakfast casserole. A little cheddar adds flavor, while the cottage cheese provides moisture and extra protein without needing protein powder.

The recipe makes four breakfast portions. Cook the vegetables briefly before mixing them into the eggs; this releases some of their moisture and helps the center set more evenly. Let the bake stand for a few minutes before cutting.

Why Make This Recipe
- The base uses ordinary eggs and cottage cheese.
- Four portions make breakfast prep manageable.
- Spinach and pepper add color without requiring a separate side dish.
Ingredient Notes and Substitutions
Use plain 2% cottage cheese, approximately 2 cups by volume. Weighing 450 g makes the nutrition estimate more consistent. If the cottage cheese has a pool of separated liquid, stir it before measuring; do not substitute a very wet fresh cheese.
Six large eggs are the base. Blending the eggs and cottage cheese makes a smoother texture, while whisking leaves small curds. Either method can work; the cooking checks stay the same.
Chop the spinach and pepper fairly small. The short skillet step removes water that would otherwise collect in the casserole. Allow the vegetables to cool slightly before adding them to the eggs.
How to Make High Protein Cottage Cheese Egg Bake with Spinach
1. Prepare the dish
Heat the oven to 375°F (190°C), conventional setting. Lightly grease an 8-inch square baking dish. Set a skillet over medium heat and add the measured teaspoon of olive oil.
2. Cook the vegetables
Add the diced pepper and cook for 3–4 minutes, stirring, until beginning to soften. Add the spinach and cook for another 1–2 minutes, until wilted and excess liquid has evaporated. Set aside to cool for about 3 minutes.
3. Mix the eggs
Whisk the eggs, cottage cheese, garlic powder, salt, and pepper in a large bowl. For a smoother bake, blend the eggs and cottage cheese first, then stir in the seasonings.
4. Assemble
Stir the slightly cooled vegetables and half the cheddar into the egg mixture. Pour into the prepared dish and sprinkle the remaining cheddar evenly over the surface.
5. Bake until set
Bake for about 30–35 minutes. Check the center with a thermometer; an egg dish should reach at least 160°F (71°C). It should be set rather than liquid when gently moved. If the top browns too quickly, cover loosely with foil and continue cooking.
6. Rest and cut
Let the bake stand for 5 minutes, then cut into four equal pieces. Serve warm or portion into shallow containers for prompt refrigeration. Do not leave it cooling on the counter for an extended period.
Tips and Troubleshooting
Avoid a watery center
Cook off vegetable moisture before mixing. A deeper or smaller dish may also need more time than the stated pan.
Keep the texture tender
Start checking near 30 minutes and stop when the center is set and safely cooked. Extra baking time can make eggs rubbery.
Portion consistently
Cut the dish into four equal pieces. The estimated nutrition applies to one quarter of the whole recipe, without sides.
Variations
- Replace the pepper with finely chopped broccoli, cooking it until tender and removing excess water first.
- Use shredded mozzarella instead of cheddar for a milder flavor. Recalculate nutrition if the cheese changes.

Notes
What to Serve With It
Pair a warm slice with toast, fruit, or roasted potatoes. Those additions are separate from the stated nutrition. For a lunch portion, serve with a green salad and a simple dressing.
Storage and Reheating
Refrigerate in shallow containers within 2 hours, or within 1 hour above 90°F (32°C). Keep at 40°F (4°C) or below for 3–4 days. Reheat covered in the microwave until the center reaches 165°F (74°C). For longer storage, freeze individual cooled portions for up to 2 months for best quality, then thaw in the refrigerator before reheating.
Frequently Asked Questions
Does it taste strongly of cottage cheese?
The eggs, cheddar, and vegetables contribute most of the savory flavor. Blending reduces the visible curds, but cottage cheese brands vary in saltiness.
Can I use egg whites only?
That changes the texture and the nutrition. This version is written for whole eggs, so an all-white version needs its own quantities and cooking checks.
How much protein is in a serving?
The accompanying ingredient-based calculation estimates about 27 g protein per quarter of the bake. Brand choices and portion size change the result.
