How To Make Spinach & Mushroom Cottage Cheese Quiche:

Here are the step-by-step instructions to make this recipe.

Step 1: Preheat and Prep

Prep the spelt flour pie crust or your favorite pie crust recipe.
Preheat your oven to 400 degrees F. As the oven is preheating, prep your mushrooms, onions and spinach by washing and dicing the mushrooms, cutting the onions into rings and cutting tough stems off the spinach. Blend the cottage cheese.

Step 2: Roast the Vegetables

Place the mushrooms and onions in separate areas on a sheet pan and drizzle with olive oil. Mix the mushrooms gently to coat and roast for fifteen minutes. Now, add the spinach (also drizzled with olive oil) to the baking sheet in its own area and roast all vegetables for another five minutes.

Step 3: Make the Filling

While the vegetables are roasting, make your filling by combining the beaten eggs, blended cottage cheese, shredded cheddar cheese, salt, pepper and herbs in a mixing bowl.

Step 4: Combine and Pour

When the vegetables are roasted, reduce the heat on your oven to 375 degrees F. Combine the filling with the roasted mushrooms and spinach and pour the mixture into your prepared crust.

Step 5: Top with Onions and Bake

Use the roasted red onion slices to decorate the top of your quiche as shown. Bake the quiche at 375 degrees F for approximately 40 minutes or until the edges are set and it is just slightly jiggly in the center.

Step 6: Rest and Serve

Allow the quiche to rest for 10-20 minutes or cool entirely before serving. This will allow it to set properly and make it easier to slice. Serve and enjoy!

Expert Tips

• To make this quiche even easier, you can purchase your pie crust.
• Try baking the filling in muffin cups with or without a crust for a great convenient option for snacks or on-the-go.
• Get creative and try your own flavour combinations such as broccoli and goat cheese, sundried tomato and pesto, ham and cheddar, or caramelized onion and gruyere.
• Take care not to overcook the quiche. It's done when the edges are set and the centre is just slightly jiggly.
