I love crustless quiches because they're easy to prepare and they make a delicious high protein meal. The ingredients in this flavorful spinach quiche include Cheddar cheese, bacon, and seasonings.

Serve this quiche with a cup of soup, baked beans, or a simple tossed salad for a fabulous lunch, brunch, or evening meal. Feel free to sauté 1/2 to 1 cup of sliced fresh mushrooms with the onions.

Ingredients

  • 4 slices thick-cut bacon, diced

  • 1/2 cup chopped onion

  • 1 (5- to 6-ounce) package fresh spinach

  • 1 cup (4 ounces) shredded cheddar, or cheddar jack blend

  • 1 1/4 cups low-fat milk

  • 1/4 cup all-purpose flour

  • 5 large eggs

  • 1 large egg white

  • 1/4 teaspoon freshly ground black pepper

  • 3/4 teaspoon salt

  • 1/4 teaspoon onion powder

  • 1 pinch dried oregano leaves

  • 1 pinch sweet paprika, optional

Steps to Make It

  3. In a large skillet or sauté pan cook the diced bacon until fat is rendered and the bacon is crisp. Remove to paper towels.

  4. Pour off all but about 1 teaspoon of the bacon grease. Save the bacon grease to use in cornbread or for a flavorful fat for sautéing onions or other vegetables.

  5. Add the onion to the pan and cook over medium heat, stirring, until just tender.

  6. Add the spinach leaves and cook, stirring constantly, until spinach is wilted and any excess water clinging to the leaves has evaporated.

  7. Transfer the spinach mixture to the baking dish. Top evenly with the bacon, then with the cheese.
