Egg, Cheese, and Onion Quiche

A classic quiche Lorraine has long been one of my favorite dishes. You can make a good crustless, meatless in the slow cooker, drawing upon that gentle heat. I like to use a smoked salt to supply the smoky flavor that would ordinarily give. Serve with a crispy green salad.

Recipe information

  • Yield

    serves 4 to 6

Ingredients

2 tablespoons vegetable oil
1 onion, cut in half and thinly sliced
8 ounces fresh mushrooms, sliced
Smoked salt to taste
Freshly ground black pepper to taste
1 cup toasted bread crumbs
1 cup (about 1/4 pound) grated Gruyère or Swiss cheese
6 large eggs
1 cup sour cream
Pinch of freshly grated nutmeg

Preparation

  1. Step 1

    In a large sauté pan, heat the oil and sauté the onion until wilted and starting to brown, 5 to 7 minutes. Add the mushrooms and continue to sauté until both the onion and the mushrooms are golden brown, 5 to 7 minutes more. Add the smoked salt and pepper to taste.

    Step 2

    Spread the bread crumbs evenly over the bottom of the slow cooker insert. Using a slotted spoon so any excess moisture can drain off, carefully spread the sautéed mushrooms and onion on top of the bread crumbs, being careful not to displace the layer of bread crumbs. Spread the cheese in a single layer on top of the mushrooms and onions.

    Step 3

    In a blender or food processor, combine the eggs, a dash of salt, the sour cream, and the nutmeg until thoroughly blended.

    Step 4

    Gently pour the egg mixture over the contents of the slow cooker insert. Cover and cook on low for 2 to 3 hours, or until the center still jiggles slightly but is just about set. (Always stop the cooking before the quiche is completely set. If you wait until the top is set, the quiche is likely to be dry and overcooked.)

    Step 5

    Serve by carefully spooning a generous portion of the quiche out of the slow cooker insert and onto plates or shallow bowls.

  2. Variation

    Step 6

    For a nontraditional “americanized” crust, try spreading a cup or two of grated potatoes evenly over the bottom of a well-oiled or buttered slow cooker insert, then proceeding with the recipe above.

  3. Suggested Beverage

    Step 7

    An Alsatian Pinot Gris or other nice light, dry white wine would be nice. I think I’d just as well enjoy a sparkling wine, Prosecco, or champagne, too.
