Christmas in July Casserole–an easy, high-protein and creamy egg bake with cheddar, tomatoes, and green onion.

Christmas in July Casserole
Any time I eat an egg casserole I think of Christmas. It seems egg casseroles are a staple for Christmas morning. Well even though we’re in the middle of summer I wanted to try making this egg bake that is adapted from the Starbucks egg bites. You’ll blend the eggs with yogurt and cottage cheese. This gives the casserole a super creamy texture and lots of protein! It’s just Greg and me at the cabin this week so I made this casserole to serve only 3-4 people. But you can easily double this recipe to serve more people!
Ingredients/Substitution Ideas
- Eggs
- Cottage cheese
- Plain greek yogurt
- Garlic powder
- Onion powder
- Black pepper
- Kosher salt
- Cheddar cheese–or another kind of cheese like pepper jack
- Tomatoes
- Green onion
Steps
Heat oven to 350° F. Add eggs, cottage cheese, yogurt, garlic powder, onion powder, pepper and salt to a blender. Blend until smooth.

Spray a 10 inch oven safe skillet with non-stick cooking spray (or a square baking dish). Pour the egg mixture into the pan. Sprinkle in the cheese, tomatoes and green onions.

Bake for 20 minutes, or until eggs are set. Slice and serve.

Notes/Tips
- Serve with toast and orange juice.
- This recipe is gluten free and fairly low carb.
- I used a 10 inch oven safe skillet.
- The center should no longer jiggle and a knife inserted in the middle should come out clean. Depending on your oven, you might need a few extra minutes.
- Try swapping the tomatoes for chopped spinach, bell peppers, or cooked mushrooms, or adding crumbled bacon or ham for a meatier version. If you do add bacon or ham I would reduce the amount of salt.
- Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months. This is great for an easy breakfast. Warm up in 30 seconds in the microwave.
- Other recipes you can make with cottage cheese are Slow Cooker Zucchini Noodle Lasagna and Instant Pot Million Dollar Casserole.
