How To Make It
Step One: Preheat the oven and prepare the baking dish.
Preheat the oven to 375F. Prep a 9 inch glass pie dish or 8×8 baking dish using a non stick spray.
Step Two: Prep the veggies.
Add olive oil to a medium skillet. Saute mushrooms and red bell pepper until soft. Add fresh spinach and continue cooking until wilted. If using frozen spinach, thaw it in the microwave and squeeze out extra moisture before adding to sauteed mushrooms and peppers. Cook all veggies until excess moisture evaporates and then remove from heat.


Step Three: Make the egg filling.
In a large glass bowl whisk eggs together. Add cottage cheese and mix until combined. Tip: For a creamier texture you can blend cottage cheese first in a food processor first and then add blend in with eggs- I recommend this extra step.
Step Four: Mix egg filling with veggies.
Stir cooked vegetables into egg and cottage cheese mixture. If using shredded cheese, add into the mixture and stir to combine.
Step Five: Add herbs and spices.
If using, add garlic powder, onion powder and Italian seasoning to the filling. Mix to incorporate evenly.


Step Six: Transfer mixture and bake.
Pour filling mixture into a prepared glass pie dish or 8×8 baking dish. Bake for about 30 minutes or until the center is cooked through and the top is golden brown.
Step Seven: Rest and Cool.
Once removed from the oven, let the quiche rest and cool for 10-15 minutes before serving. The quiche will continue to set as it cools.

Tips/Variations/Substitutions
- Versatile: One of the best things about this high-protein quiche recipe is the endless variety of vegetables and types of cheese combinations you can create. You can also add meats like uncured ham or sausage for extra flavor and protein. Some other combinations to try include:
- Broccoli with ham and cheddar cheese
- Sweet potatoes, spinach, sundried tomato and goat cheese
- Caramelized onions, mushrooms and swiss cheese.
- Italian sausage, green bell peppers and cheddar cheese
- Cherry tomatoes, basil, garlic and parmesan cheese
- Fresh or frozen vegetables: For this recipe, you can use either fresh vegetables or frozen vegetables, making it an easy way to use up leftovers or skip an extra trip to the grocery store. Tip: if using frozen vegetables, thaw first and remove any excess moisture.
- Double Up: This recipe is also easy to make in bulk, making it perfect for meal prep, saving for later, or sharing with friends and family. The egg and cottage cheese base stays the same, while allowing you to easily create two different flavor combinations if you’d like. For example doubling the egg filling you could make one quiche with broccoli and cheddar cheese; and one quiche with onions, mushrooms and Swiss cheese.
- Eggs whites or whole eggs: You can use whole eggs, egg whites or a combination of the two for this recipe. For each 1 whole egg, substitute with 3 tablespoons of egg whites.
