To make a great Caramelized Onion Swiss Quiche, gather these items: - 1 pre-made pie crust (or homemade if preferred) - 3 large onions, thinly sliced - 2 tablespoons olive oil - 1 tablespoon butter - 4 large eggs - 1 cup heavy cream - 1 cup grated Swiss cheese - 1 teaspoon dried thyme - Salt and pepper to taste - Fresh parsley for garnish (optional) You will need some key tools to make your quiche: - A large skillet for cooking onions - A mixing bowl for whisking - A whisk or fork for mixing - A pie dish for baking - A sharp knife for slicing Fresh ingredients make a big difference. Look for onions that are firm and free from dark spots. Choose eggs that have bright, unbroken shells. For Swiss cheese, pick a block rather than pre-grated; it melts better. Fresh thyme adds great flavor, so if you can, use it instead of dried. Always check the dates on cream to ensure freshness. Start by slicing the onions thinly. I like to use three large onions for a rich taste. Heat two tablespoons of olive oil and one tablespoon of butter in a large skillet over medium heat. Add the sliced onions to the pan. Sprinkle with a pinch of salt to help them cook down. Sauté for about 15 to 20 minutes. Stir them often until they turn golden brown and smell sweet. This step is key for great flavor. Once done, set them aside to cool slightly. In a separate bowl, crack four large eggs. Add one cup of heavy cream to the eggs. Now, whisk them together until they blend well. Add one teaspoon of dried thyme, along with salt and pepper to taste. This mixture will give your quiche a smooth, creamy filling. Make sure to mix well, so every bite has a burst of flavor. Grab your pre-made pie crust and place it in a pie dish. Spread the caramelized onions evenly on the bottom. Then, pour the egg and cream mixture over the onions. Top it off with one cup of grated Swiss cheese. Now, it’s time to bake! Place the quiche in a preheated oven at 375°F (190°C). Bake for about 30 to 35 minutes. You want it puffed and golden brown. A knife should come out clean when inserted in the center. Once baked, let it cool for about 10 minutes before slicing. This wait helps keep the slices neat. For the full recipe, check the details above. To get sweet, golden onions, watch the heat closely. Start with medium heat and add the onions to the hot pan. A pinch of salt helps draw out moisture. Stir often and let them cook slowly for about 15-20 minutes. If they cook too fast, they may burn, so lower the heat if needed. The goal is to get that rich, deep flavor without any bitterness. For the perfect quiche texture, balance is key. Use a mix of eggs and heavy cream for a rich filling. This blend gives the quiche a creamy, soft texture. Make sure to whisk the eggs and cream well. This helps incorporate air, making the quiche light and fluffy. Pour the mixture over the onions and cheese gently. This way, everything stays evenly distributed. Serve your quiche warm for the best taste. Slice it into wedges and garnish with fresh parsley for color. A simple side salad makes a great pair. Think of mixed greens with a light vinaigrette. This adds freshness to your meal. You can also add a glass of chilled white wine for a special touch. For the full recipe, check out the detailed steps above. {{image_2}} If you want to switch things up, go ahead! You can use shallots instead of onions. Shallots add a sweet and mild taste. For cheese, try Gruyère or cheddar; both work well. If you lack heavy cream, use milk or a milk alternative. You can even swap the pie crust for a hash brown crust for a fun twist. Mixing flavors can change your quiche game. Add cooked bacon or ham for a meatier dish. Spinach or kale can add greens and nutrients. A sprinkle of nutmeg provides warmth and depth. For a spicy kick, add a pinch of red pepper flakes. Experiment with fresh herbs like basil or chives to brighten the flavor. To make a gluten-free quiche, use a gluten-free pie crust or a crustless version. For a dairy-free option, choose a nut-based cream or coconut cream. Vegan cheese can replace Swiss cheese. You can also use silken tofu blended with nutritional yeast for a creamy filling. These swaps let everyone enjoy this dish. To store leftover quiche, let it cool completely. Then, wrap it tightly in plastic wrap or place it in an airtight container. This keeps the quiche fresh for up to three days in the fridge. Make sure to label it, so you remember when you made it! When you are ready to eat, preheat your oven to 350°F (175°C). Place the quiche in a baking dish. Cover it with foil to keep moisture in. Heat for about 15-20 minutes. You can also microwave slices for quick reheating, but they may lose some texture. If you want to freeze quiche, wrap it well before it cools. Use plastic wrap and then foil. This helps prevent freezer burn. You can freeze it for up to three months. To reheat, thaw it in the fridge overnight. Then, bake at 350°F (175°C) until warm. Enjoy your delicious quiche later!

Cheddar, goat cheese, or feta can work well. Each cheese adds its own flavor. If you choose a stronger cheese, like blue cheese, use less to avoid overpowering the dish. Mixing cheeses can also create a fun flavor profile. Just remember to keep the creamy texture that Swiss cheese provides. Quiche pairs well with many side dishes! A fresh green salad is a great choice. You can also serve it with roasted vegetables or a light soup. For a brunch, add fresh fruit or a fruit salad.

Ingredients

3 large onions, thinly sliced

2 tablespoons olive oil

1 tablespoon butter

4 large eggs

1 cup heavy cream

1 cup grated Swiss cheese

1 teaspoon dried thyme

Salt and pepper to taste

Fresh parsley for garnish (optional)

Instructions
 

Preheat your oven to 375°F (190°C).

    In a large skillet, heat the olive oil and butter over medium heat. Add the sliced onions and sprinkle with a pinch of salt. Sauté for about 15-20 minutes, stirring occasionally, until the onions are golden brown and caramelized.

      While the onions are cooking, in a separate bowl, whisk together the eggs, heavy cream, thyme, salt, and pepper until well combined.

        Once the onions are caramelized, remove them from heat and allow to cool slightly.

          Place the pre-made pie crust into a pie dish and spread the caramelized onions evenly on the bottom of the crust.

            Pour the egg and cream mixture over the onions, then sprinkle the grated Swiss cheese on top.

              Bake in the preheated oven for about 30-35 minutes, or until the quiche is puffed and golden brown around the edges, and a knife inserted in the center comes out clean.

                Remove from the oven and let it cool for about 10 minutes before slicing.
