Step‑by‑Step Instructions for Spinach and Mushroom Quiche Muffins
Step 1: Prep Oven & Muffin Pan
Start by preheating your oven to 375°F (190°C). While it heats, grab a 12-cup muffin pan and lightly spray each cup with cooking spray to prevent sticking. This will ensure that your Spinach and Mushroom Quiche Muffins release easily after baking, giving them a beautiful, golden color.
Step 2: Prepare Vegetables
In a skillet over medium-high heat, add your sliced mushrooms, cooking them for 2-3 minutes until they are lightly browned and begin to release their moisture. Next, fold in the roughly chopped spinach and cook for just 1 more minute until wilted. Once cooked, remove from heat and allow to cool slightly before adding to your egg mixture.
Step 3: Mix Egg Base
In a large mixing bowl, beat together the room temperature eggs until they are well combined. Add the finely grated Parmesan cheese, milk, garlic powder, onion powder, salt, and black pepper. Whisk everything together until the mixture is smooth and cohesive, preparing a flavorful base for your Spinach and Mushroom Quiche Muffins.
Step 4: Combine Ingredients
Once the sautéed vegetables have cooled slightly, fold them into the egg mixture until evenly distributed. This ensures that each muffin is packed with flavorful spinach and mushrooms, creating a delicious and nutritious bite in every quiche muffin. Be gentle to maintain the fluffy texture as you combine these elements.
Step 5: Fill Muffin Cups
Using a ladle or spoon, pour the quiche mixture into the prepared muffin cups, filling each one about ¾ full. This allows room for the muffins to puff up while baking without overflowing, ensuring a perfectly-shaped Spinach and Mushroom Quiche Muffins with lovely domed tops.
Step 6: Bake
Place the muffin pan in the preheated oven and bake for 18-20 minutes. Check for doneness by lightly touching the center of a muffin; it should spring back, although it may still be slightly jiggly. A golden-brown top is an excellent indicator that they are ready to come out of the oven.
Step 7: Cool
Remove the muffin pan from the oven and let the quiche muffins cool in the pan for about 5 minutes. This cooling period is crucial as it helps them firm up slightly. Then, gently run a knife around the edges and carefully transfer the muffins to a wire rack to cool completely before serving.

Expert Tips for Spinach and Mushroom Quiche Muffins
-
Prep Ingredients First: Get all your ingredients ready before starting. This approach ensures smoother preparation and prevents any last-minute rush.
-
Use Room Temperature Eggs: For the best texture, always use eggs at room temperature. This helps them mix more evenly into your Spinach and Mushroom Quiche Muffins.
-
Avoid Overcooking Veggies: Sauté mushrooms and spinach just until tender. Overcooking could lead to excess moisture, which can make your muffins soggy.
-
Cool Vegetables Before Mixing: Let your sautéed veggies cool before adding them to the egg mix. This prevents curdling and helps maintain a fluffy structure.
-
Don’t Overfill Muffin Cups: Fill each muffin cup about ¾ full. This gives space for the muffins to rise without overflowing, ensuring even baking and beautiful dome shapes.
Make Ahead Options
These Spinach and Mushroom Quiche Muffins are perfect for busy home cooks looking to save time! You can prepare the vegetable filling (sautéed mushrooms and spinach) up to 3 days in advance; just refrigerate it in an airtight container. Additionally, you can mix the egg base (eggs, cheese, milk, and seasonings) and store it separately for up to 24 hours in the fridge. When you’re ready to bake, simply combine the chilled filling with the egg mixture, fill the muffin cups, and bake as directed. This ensures your muffins taste just as delicious, even after being prepped ahead! Enjoy the convenience of homemade goodness all week long.
