How to Make a Cottage Cheese Egg Bake

This bake can be assembled the night before, covered and refrigerated, then baked the next morning.

Cook and cool the quinoa beforehand. Prepare an 8×8-inch baking dish by spraying it with nonstick spray. If baking immediately, preheat the oven to 350°F (175°C).

Serving Suggestions

Let the bake cool briefly, then cut into individual portions. Serve with fresh berries, sliced melon or a simple fruit salad. Crisp bacon or a tossed green salad make great accompaniments for a larger brunch. Garnish with a dollop of sour cream, chopped parsley, sliced green onions or extra Parmesan, if desired.

Recipe FAQs

Can I swap the cottage cheese for another cheese?

Yes. Ricotta gives a similar texture, or you can use more shredded cheese, though texture and protein content will change slightly.

Is it vegetarian?

Yes, if you use vegetarian-friendly Parmesan or omit cheeses made with animal rennet. Check labels when cooking for strict vegetarians.

Can I add meat to this casserole?

Absolutely. Cooked crumbled bacon, chopped ham or cooked sausage work well—add no more than about ½ cup so the balance of egg and vegetables remains.

Can I make this casserole ahead of time?

Yes. Assemble the unbaked casserole, cover and refrigerate overnight. Remove it from the fridge 30–45 minutes before baking and bake as directed.

Equipment

  • 8×8 baking dish

Ingredients

  • 1 ½ tablespoons unsalted butter
  • 1 cup chopped onion (about half a medium)
  • ¾ teaspoon dried thyme
  • 1 ½ cups small broccoli florets (about 4 ounces)
  • 8 ounces mushrooms, stemmed and sliced thin
  • 2 tablespoons chopped fresh Italian parsley
  • ½ teaspoon garlic powder (or 2 fresh cloves, finely chopped)

  • 10 large eggs
  • ⅔ cup cottage cheese
  • ⅔ cup finely grated Parmesan cheese, divided
  • ½ teaspoon sea salt
  • ¼ teaspoon ground black pepper
  • ¼ teaspoon red pepper flakes (optional)

Instructions

Prepare the dish

  • Lightly spray an 8×8-inch glass or ceramic baking dish with nonstick spray. Sprinkle the cooked quinoa evenly over the bottom.

Sauté aromatics

  • In a large skillet over medium-low heat, melt ½ tablespoon butter. Add the onion and sauté until softened, about 3 minutes. Stir in the garlic and thyme for 1 minute. Transfer to the baking dish.

Cook the mushrooms

  • Add the remaining 1 tablespoon butter to the skillet. Add the mushrooms and cook until browned and moisture has mostly evaporated. Add to the baking dish.

Add broccoli and herbs

  • Steam broccoli until just tender, 2–3 minutes, then chop and add to the dish with parsley. Stir to combine all vegetables.

Blend the egg mixture

Assemble the casserole

  • Pour the egg mixture over the vegetables in the baking dish and spread evenly. Sprinkle the remaining ⅓ cup Parmesan over the top.

Bake and serve

  • To serve right away: Bake at 350°F for about 50 minutes until golden and firm. Let cool slightly before slicing.
  • To make ahead: Cover the unbaked casserole and refrigerate overnight. Remove from the fridge 30–45 minutes before baking and bake as directed.
