Step‑by‑Step Instructions for Spinach and Mushroom Quiche Muffins
Step 1: Preheat and Prepare the Muffin Pan
Begin by preheating your oven to 375°F (190°C). While your oven heats up, grab a 12-cup muffin pan and spray it generously with cooking spray to prevent sticking. This step ensures that each Spinach and Mushroom Quiche Muffin releases easily after baking, allowing for a beautiful presentation.
Step 2: Slice and Chop the Vegetables
Take the mushrooms and slice them into 1/4-inch thick pieces. Set the sliced mushrooms aside and then roughly chop your fresh spinach. These vibrant greens will complement the earthy flavor of the mushrooms, creating a delightful blend in your muffins. Keep the vegetables separate as they will be sautéed individually.
Step 3: Sauté the Mushrooms
In a medium-sized skillet, heat a tablespoon of oil over medium-high heat. Once hot, add the sliced mushrooms and sauté them for about 2-3 minutes, until they are browned and have released their moisture. This process enhances their umami flavor, making them a delicious addition to your Spinach and Mushroom Quiche Muffins.
Step 4: Add Spinach to the Mushrooms
Next, incorporate the chopped spinach into the skillet with the sautéed mushrooms. Cook together for about 1 minute, or until the spinach has wilted down significantly. This step not only infuses the mushrooms with the fresh taste of spinach but also eliminates excess moisture, which is key to preventing soggy muffins.
Step 5: Cool the Vegetable Mixture
Once the spinach is wilted, transfer the vegetable mixture to a plate and allow it to cool slightly. This cooling period is essential as adding hot vegetables to the eggs can cause them to cook prematurely, compromising the texture of your Spinach and Mushroom Quiche Muffins.
Step 6: Whisk the Egg Mixture
In a large mixing bowl, crack 4 large room-temperature eggs and beat them until well combined. Gradually whisk in the grated Parmesan cheese, milk, garlic powder, onion powder, salt, and black pepper. This creamy mixture will serve as the custard base for your muffins, ensuring they are rich and flavorful.
Step 7: Combine Vegetables and Egg Mixture
Once the vegetable mixture has cooled, gently fold it into the egg mixture using a spatula. Ensure that the mushrooms and spinach are evenly distributed throughout the egg mixture for balanced flavor in every bite of your Spinach and Mushroom Quiche Muffins.
Step 8: Fill the Muffin Cups
Carefully spoon the combined mixture into the prepared muffin cups, filling each about three-quarters full. Be careful not to overfill, as the muffins will rise during baking. This creates perfectly portioned, crustless mini quiches that are not only delicious but also visually appealing.
Step 9: Bake Until Set
Place the muffin pan in the preheated oven and bake for 18-20 minutes. Keep an eye on them as they bake; they should be set but slightly jiggly in the center when touched. Also, the tops will turn a lovely golden-brown, making your Spinach and Mushroom Quiche Muffins look irresistible.
Step 10: Cool and Serve
After baking, allow the muffins to cool in the pan for about 5 minutes. This helps them firm up before transferring to a wire rack. Once cooled slightly, gently remove each muffin from the pan. Now they’re ready to be enjoyed warm or stored for a delightful breakfast option throughout the week!

Expert Tips for Spinach and Mushroom Quiche Muffins
- Avoid Excess Moisture: Sautéing the spinach and mushrooms until all moisture evaporates will help prevent soggy muffins.
- Cool Before Mixing: Let the vegetable mixture cool before adding it to the eggs. Hot veggies can cook the eggs, altering the texture.
- Don’t Overfill: Fill muffin cups about three-quarters full to allow room for rising. Overfilling can lead to messy muffins.
- Check for Doneness: The muffins should feel firm yet slightly jiggly in the center when done. This ensures a perfect texture without being overcooked.
- Flavor Variations: Feel free to experiment with herbs or different cheeses to elevate the flavors of your Spinach and Mushroom Quiche Muffins.
