This breakfast casserole is perfect for Shabbat mornings and holidays: cubes of day-old challah baked with eggs, cottage cheese, milk, sautéed onion, peppers and garlic. Assemble it the night before and bake in the morning.
Cook the Vegetables First
Sauté the onion and peppers until soft and golden; this removes their moisture and makes them sweet. Toss them with the challah cubes, pour over the egg and cottage cheese mixture, and let it soak overnight in the fridge so the bread absorbs the custard evenly.
Kosher Notes
With cottage cheese, milk and butter, this is a dairy (milchig) dish. Use dairy products with a reliable hechsher and check each egg for blood spots. Baking a fresh casserole on Shabbat morning isn’t permitted, so for Shabbat, bake it before Shabbat and keep it warm according to your practice.
Make-Ahead
Assemble the night before, adding 10 to 15 minutes to the baking time. Leftovers keep for 3 days.

Method
- Preheat oven to 350°F. Grease a 9x13 inch baking dish with butter.
- Heat olive oil in a large skillet over medium heat. Add diced onion and cook for 5 minutes until softening.
- Add bell peppers to the skillet and cook for 8-10 minutes, stirring occasionally, until vegetables are soft and lightly caramelized.
- Add minced garlic and cook for another minute until fragrant. Remove from heat and let cool slightly.
- In a large bowl, whisk together eggs, cottage cheese, milk, salt, pepper, and paprika until well combined.
- Add the cubed challah bread to the egg mixture and gently fold to combine. Let sit for 5 minutes to allow bread to absorb the liquid.
- Fold in the cooked vegetables and half of the chopped chives.
- Pour the mixture into the prepared baking dish and spread evenly. Sprinkle remaining chives on top.
- Bake for 40-45 minutes until the center is set and the top is golden brown. A knife inserted in the center should come out clean.
- Let cool for 10 minutes before serving. Cut into squares and serve warm.
