Ingredients You’ll Need
- 12 large eggs: The base of your breakfast casserole. Fresh eggs yield the best texture and flavor.
- 2 cups cottage cheese (whole milk): This adds a creamy element and a boost of protein. You can substitute with ricotta or Greek yogurt for a different flavor profile.
- ¼ cup whole milk, half and half, or plain yogurt: This moisture helps create a rich texture. Choose half and half for creaminess or yogurt for a lighter twist.
- ½ teaspoon salt: Enhances the flavors of the other ingredients.
- ½ teaspoon pepper: Adds a mild kick to your dish.
- ½ teaspoon garlic powder: For a touch of savory depth.
- ½ teaspoon oregano: This aromatic herb brings an Italian flair.
- 8-12 ounces pepper jack cheese, grated: It gives your casserole a delightful spiciness. Feel free to replace it with cheddar if you prefer a milder flavor.
- 2-3 cans (4-ounce) diced chilies: They add a zesty punch. Look for mild varieties if you want to reduce the heat.
- ½ cup green onions or cilantro: Brighten up the dish with fresh herbs. You can mix both for extra flavor.
How to Make Breakfast Casserole
- Preheat the oven: Set your oven to 350°F to ensure it’s perfectly heated for your casserole.
- Blend the base: In a blender, combine 12 large eggs, 2 cups of cottage cheese, ¼ cup of either whole milk, half and half, or plain yogurt, ½ teaspoon of salt, ½ teaspoon of pepper, ½ teaspoon of garlic powder, and ½ teaspoon of oregano. Blend until smooth and homogenous.
- Mix in the goodies: Pour the blended mixture into a large bowl. Stir in 8-12 ounces of grated pepper jack cheese, 2-3 cans of diced chilies, and most of the ½ cup of green onions or cilantro. Reserve a little for garnishing. Mix well but avoid blending.
- Prepare for baking: Grease a 9×13-inch baking dish, then pour the mixture inside. Top with the reserved cheese.
- Bake to perfection: Place the dish on the lower-middle rack of the oven and bake for 35-50 minutes. The casserole is done when it’s puffed in the center. If the edges darken too much, tent them with foil halfway through baking.
- Garnish & serve: Once baked, sprinkle with the remaining green onions or cilantro. This casserole can be enjoyed warm or at room temperature, making it a convenient choice.
Storing & Reheating
To keep your casserole fresh, store it in an airtight container at room temperature for up to 2 hours after baking. After that, it’s best to refrigerate any leftovers for up to 3-4 days. For longer storage, you can freeze the casserole for up to 3 months. When ready to enjoy, reheat individual portions at 350°F for about 15-20 minutes or until heated through. Keep in mind that while reheating, you may lose a bit of texture, but a sprinkle of fresh herbs on top can help refresh its flavor.
Chef’s Helpful Tips
- Avoid sogginess: Ensure all mixed ingredients are well-combined to achieve a uniform texture.
- Egg temperature matters: Always use room temperature eggs for a fluffier casserole.
- Timing is key: Check the casserole halfway through baking. Rotate it for even cooking and cover if needed.
- Mix up the flavors: Don’t hesitate to experiment with different cheeses or add vegetables like spinach or bell peppers for a personalized touch.
- Prep ahead: You can prepare the mixture and store it in the fridge overnight. Just pour it into your baking dish fresh the next morning.
