Ingredients for Keto Crustless Quiche with Mushrooms and Tomatoes

Making this Keto Crustless Quiche with Mushrooms and Tomatoes is simple. The ingredients are mostly whole foods, and you can find them easily in your local grocery store. Here’s what you’ll need:

For the Quiche Base:

6 large eggs
1 cup heavy cream (or coconut cream for dairy-free)
1 cup shredded cheese (cheddar, mozzarella, or a blend)
1/2 cup diced onions (optional)
Salt and pepper to taste

For the Veggies:

1 cup mushrooms, sliced (button or cremini mushrooms work best)
1/2 cup cherry tomatoes, halved
1 tablespoon olive oil
1/2 teaspoon garlic powder
1/2 teaspoon dried thyme (or fresh thyme, if available)
A pinch of red pepper flakes (optional)

For an Extra Protein Boost (optional):

1/2 cup cooked bacon bits or diced ham (for a Crustless Meat Lovers Quiche variation)

Preparation Steps for Keto Crustless Quiche with Mushrooms and Tomatoes

Step 1: Prepare the Mushrooms and Tomatoes

The first step is to prepare the mushrooms and tomatoes for the quiche. Heat a tablespoon of olive oil in a medium skillet over medium heat. Add the sliced mushrooms and sauté them until they release their moisture and become golden brown, which should take about 5-7 minutes. During this time, add the garlic powder, dried thyme, and red pepper flakes to season the mushrooms.

Once the mushrooms are cooked, remove them from the skillet and set them aside to cool slightly. In the same skillet, add the halved cherry tomatoes and sauté them for about 2-3 minutes, just to soften them up. If you want a more roasted effect, you can also opt to roast the mushrooms and tomatoes in the oven at 400°F (200°C) for 10-12 minutes, or until tender and slightly caramelized, for a Roasted Veggie Quiche twist.

Step 2: Make the Quiche Filling

While the mushrooms and tomatoes are cooling, whisk together the eggs and heavy cream in a large bowl. Add a pinch of salt and pepper to taste, and then stir in the shredded cheese. If you’re using bacon or ham for a Crustless Meat Lovers Quiche, fold it into the mixture at this point. The combination of eggs, cream, and cheese creates a rich, custardy filling that’s the foundation of a great quiche.

Step 3: Combine the Ingredients

Next, incorporate the sautéed mushrooms and tomatoes into the egg mixture. Be sure to spread them out evenly so every bite of your Keto Mushroom Quiche is filled with a balance of veggies and protein.

You can also add some extra seasoning here—perhaps a little more thyme or a sprinkle of smoked paprika to enhance the earthy flavors of the mushrooms.

Step 4: Bake the Quiche

Preheat your oven to 350°F (175°C). Grease a 9-inch pie dish or tart pan with cooking spray or butter to prevent sticking. Pour the quiche filling into the dish, ensuring that the ingredients are evenly distributed.

Bake the quiche for 25-30 minutes, or until the quiche is set in the middle and slightly golden on top. You can check for doneness by inserting a toothpick into the center—if it comes out clean, your quiche is ready.

Step 5: Serve and Enjoy

Once your quiche is done, let it cool for a few minutes before slicing it into wedges. This dish can be enjoyed warm, at room temperature, or even chilled, making it a great option for meal prep.

You can garnish the quiche with fresh herbs, such as parsley or basil, or serve it alongside a simple salad for a complete meal. The flavors will deepen and improve as the quiche sits, making it an ideal dish to prepare in advance for breakfast, brunch, or a low-calorie dinner option.

Additional Variations and Tips

Dairy-Free Version: If you’re following a dairy-free or paleo diet, simply swap out the heavy cream for coconut cream and use dairy-free cheese or skip it altogether. You can also substitute eggs with a flax egg for an entirely plant-based version.
Add More Veggies: You can make this quiche more nutrient-dense by adding extra vegetables. Try spinach, bell peppers, or even artichokes for added flavor and texture. The more vegetables, the better, as they’ll keep you full for longer.
Zucchini Quiche: If you’re looking to add a bit of extra moisture and a mild flavor, shredded zucchini works wonderfully in a crustless quiche. Just make sure to squeeze out the excess water from the zucchini before adding it to the mix.
Make it a Casserole: Instead of making individual quiches, you can bake the mixture in a casserole dish for a larger batch. This method works well for feeding a crowd at a Pitch-In Breakfast or a brunch gathering.
Spice it Up: For a bit of a kick, you can add diced jalapeños or chili flakes to the filling, or top the finished quiche with a dollop of salsa or hot sauce.
Roasted Veggie Quiche: For a more savory and complex flavor, roast your mushrooms and tomatoes in the oven before adding them to the egg mixture. Roasting intensifies the natural flavors of the vegetables, making them perfect for a Roasted Veggie Quiche variation.
