How to Make Crustless Tuna Breakfast Quiche Recipe
Step 1: Prepare Your Baking Dish
Start by preheating your oven to 350 degrees Fahrenheit and lightly greasing an 8-inch pie dish or any similar baking dish with cooking spray or butter. This step ensures that your quiche won’t stick and will come out clean and picture-perfect once baked.
Step 2: Whisk the Egg Mixture
In a medium bowl, whisk together the eggs, milk, salt, black pepper, and garlic powder until fully combined and smooth. This mixture is the base that will bind your quiche ingredients and help it set into that creamy, custard-like texture we all love.
Step 3: Combine Tuna and Veggies
Next, gently fold in the drained tuna, shredded cheddar cheese, chopped onion, diced red bell pepper, and dried parsley if you’re using it. Mixing these ingredients evenly throughout ensures every bite is bursting with flavor and color.
Step 4: Bake Your Quiche
Pour the entire mixture into your prepared pan, spreading it out evenly. Bake in your preheated oven for 25 to 30 minutes, or until the quiche is set firmly in the center and has a lovely light golden top. This part is where the magic happens, transforming simple ingredients into a beautiful, hearty dish.
Step 5: Cool and Serve
Let the quiche cool for about five minutes after removing it from the oven. Cooling helps it set completely, making it easier to slice and serve beautiful pieces without losing its shape.
