Step‑by‑Step Instructions for Spinach and Mushroom Quiche Muffins
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While it warms up, take a moment to prepare a 12-cup muffin pan by generously greasing it with cooking spray. This step ensures your Spinach and Mushroom Quiche Muffins release easily after baking, resulting in perfectly shaped treats ready to nourish your busy mornings.
Step 2: Prepare the Vegetables
Slice the mushrooms into 1/4-inch thick pieces and chop the fresh spinach, keeping the two veggies separate. This prep allows for even cooking during the sautéing process. Once you’ve completed this task, you’re set to move on and bring out the flavors of these vegetables in the next step.
Step 3: Sauté the Mushrooms and Spinach
In a skillet, heat a drizzle of oil over medium-high heat. Carefully add the sliced mushrooms and sauté for about 2–3 minutes until they’re beautifully browned. Add the chopped spinach to the skillet and continue cooking for an additional minute, just until wilted. Transfer the sautéed veggies to a plate and let them cool a bit before mixing into the custard.
Step 4: Combine the Egg Mixture
In a large mixing bowl, crack the room-temperature eggs and whisk them together until well-beaten. Incorporate the grated Parmesan cheese, milk, garlic powder, onion powder, salt, and black pepper. Mix until the ingredients meld smoothly and form a delightful custard that will envelop your quiche muffins in rich flavor.
Step 5: Fold in the Vegetables
Once the sautéed spinach and mushrooms have cooled, gently fold them into the egg mixture, ensuring they are evenly distributed. This combination of flavors will elevate your Spinach and Mushroom Quiche Muffins, making each bite a savory delight. Be cautious not to overmix; you want this mixture to remain fluffy and light.
Step 6: Fill the Muffin Cups
With a ladle or a measuring cup, divide the egg and vegetable mixture into the prepared muffin cups. Fill each cup about three-quarters full to allow for rising during baking. This careful filling method helps maintain the desired muffin shape and prevents overflow, ensuring your muffins turn out perfectly fluffy and golden.
Step 7: Bake to Perfection
Slide the muffin pan into your preheated oven and bake at 375°F (190°C) for approximately 18–20 minutes. Keep an eye on them; they should be set with a slightly jiggly center when you gently tap the pan. For the best result, look for a golden top that signals a deliciously baked interior, ready to be savored.
Step 8: Cool and Enjoy
After the baking time is complete, remove the muffin pan from the oven and allow it to cool for about 5 minutes. This cooling period helps make the Spinach and Mushroom Quiche Muffins easier to handle. Then, carefully transfer them to a wire rack to cool completely, or enjoy them warm right from the muffin pan for a delightful breakfast treat!

Storage Tips for Spinach and Mushroom Quiche Muffins
Fridge: Store your Spinach and Mushroom Quiche Muffins in an airtight container for up to 5 days. This keeps them fresh and ready for a quick breakfast any morning.
Freezer: For longer storage, individually wrap each muffin in plastic wrap and place them in a freezer-safe bag. They can last up to 3 months, providing a nutritious meal prep option.
Reheating: When you’re ready to enjoy, simply microwave a refrigerated muffin for 30-45 seconds or a frozen muffin for 60-90 seconds. Alternatively, warm them in a preheated oven at 350°F for about 10 minutes for optimal texture.
Make Ahead Options
These Spinach and Mushroom Quiche Muffins are perfect for meal prep enthusiasts looking to save time on busy mornings! You can sauté the mushrooms and spinach up to 3 days in advance and store them in an airtight container in the refrigerator. Additionally, you can whisk the egg mixture and have it ready 24 hours ahead of time. Just be sure to refrigerate the mixture to maintain freshness. When you’re ready to bake, simply combine the cooled sautéed vegetables with the egg mixture, fill the muffin cups, and bake as per the original instructions. This way, you’ll have a delicious and nutritious breakfast option that’s just as flavorful and satisfying!
