Crustless Quiche Recipe (Spinach, Sausage, and Sun-Dried Tomatoes), Made Easy

Now that you have everything ready, let’s get cooking! Follow these simple steps to whip up your Crustless Quiche Recipe (Spinach, Sausage, and Sun-Dried Tomatoes).
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). This ensures that your quiche cooks evenly.
Step 2: Cook the Sausage
In a skillet, heat the olive oil over medium heat. Add the ground sausage and cook until browned, breaking it up with a spatula as it cooks. This should take about 5-7 minutes. Once done, remove from heat and set aside.
Step 3: Sauté the Onions
In the same skillet, add the diced red onions. Sauté until they become translucent and slightly caramelized, about 5 minutes. This step adds a delicious sweetness to the quiche.
Step 4: Combine Ingredients
In a large mixing bowl, whisk together the eggs, salt, and ground black pepper. Add the cooked sausage, sautéed onions, thawed spinach, sun-dried tomatoes, and shredded mozzarella cheese. Stir until everything is well combined.
Step 5: Transfer to Baking Dish
Pour the mixture into a greased 9-inch pie dish or baking dish. Spread it evenly with a spatula.
Step 6: Bake
Place the dish in the preheated oven and bake for 35-40 minutes, or until the quiche is set and lightly golden on top. A toothpick inserted in the center should come out clean.
Step 7: Cool and Serve
Once baked, remove the quiche from the oven and let it cool for about 10 minutes before slicing. This makes it easier to cut and serve.
Health-Conscious Tweaks

If you’re looking to make this quiche a bit healthier, consider these alternatives:
- Use turkey sausage instead of ground sausage for a leaner protein option.
- Substitute half of the mozzarella cheese with cottage cheese for added protein and lower fat.
- Incorporate more vegetables such as bell peppers or mushrooms for added nutrients.
- Use egg whites or a combination of whole eggs and egg whites to reduce cholesterol.
These tweaks can help you enjoy the flavors you love while keeping your meal on the lighter side.
Don’t Do This
When making your Crustless Quiche Recipe (Spinach, Sausage, and Sun-Dried Tomatoes), avoid these common pitfalls:
- Don’t skip draining the spinach well—excess moisture can lead to a soggy quiche.
- Avoid using too much salt, especially if your sausage is already seasoned.
- Don’t overmix the egg mixture, as this can make the quiche dense.
- Don’t rush the cooking of the sausage and onions; proper caramelization enhances flavor.
By following these tips, you’ll ensure your quiche turns out perfectly every time.
