Ingredients
- 2 tablespoons olive oil
- 1 pound mushrooms, sliced
- 1 small onion, finely chopped
- 1 cup grated Gruyère cheese
- 6 large eggs
- 1 cup whole milk
- 1/2 cup heavy cream
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon nutmeg
- 1 tablespoon fresh thyme leaves
Instructions
- Prepare the Vegetables: Heat the olive oil in a large skillet over medium heat. Add the sliced mushrooms and chopped onion. Sauté until the mushrooms are browned and the onions are translucent, about 5-7 minutes. Remove from heat and let cool slightly.
- Grease the Slow Cooker: Lightly grease the inside of your slow cooker with cooking spray or a little olive oil to prevent sticking.
- Layer the Ingredients: Spread the sautéed mushrooms and onions evenly across the bottom of the slow cooker. Sprinkle the grated Gruyère cheese over the vegetables.
- Mix the Egg Mixture: In a large bowl, whisk together the eggs, whole milk, heavy cream, salt, black pepper, nutmeg, and fresh thyme leaves until well combined.
- Pour the Egg Mixture: Carefully pour the egg mixture over the mushrooms, onions, and cheese in the slow cooker.
- Cook: Cover the slow cooker and cook on low for 4-5 hours or on high for 2-3 hours, until the quiche is set and a knife inserted into the center comes out clean.
- Serve: Once cooked, let the quiche cool slightly before slicing. Serve warm or at room temperature, garnished with additional fresh thyme if desired.
Cooking Notes and Tips
- Cheese Options: While Gruyère is recommended for its rich, nutty flavor, you can substitute it with Swiss cheese, cheddar, or a blend of your favorite cheeses.
- Vegetable Variations: Feel free to add other vegetables such as spinach, bell peppers, or zucchini to the quiche for added flavor and nutrition.
