Pro-Tips
- Don’t overcrowd the mushrooms: When cooking the mushrooms, make sure to give them space in the pan. Crowding will cause them to steam instead of brown, which means you’ll miss out on that rich, caramelized flavor that makes these quiches so delicious.
- Sauté vegetables properly: The key to flavorful quiches is properly cooking your vegetables before adding them to the egg mixture. This removes excess moisture and concentrates the flavors.

- Use room temperature eggs: Room temperature eggs incorporate more easily with the milk and create a smoother custard texture. If you forget to take them out ahead of time, place them in warm water for 5 minutes.
- Don’t overfill the muffin cups: Fill each cup about ¾ full to allow room for the quiches to puff up during baking without overflowing.
- Let them rest: Allow the quiches to cool for 5 minutes before removing from the pan. This helps them set and makes removal much easier.
How to Make Spinach & Mushroom Mini Quiches muffins
- Preheat your oven to 325°F (165°C). Prepare all your ingredients by washing and chopping the vegetables, and grating the cheese if needed.
- Heat olive oil in a large nonstick skillet over medium-high heat. Add sliced mushrooms in a single layer and cook undisturbed for about 4 minutes until they’re browned on the bottom.
- Stir the mushrooms and continue cooking, stirring occasionally, until they’re browned all over, about 5 more minutes. This step is crucial for developing deep flavor.
- Add the sliced onion to the skillet and cook, stirring occasionally, until it begins to soften, about 4 minutes. The onion will add sweetness and depth to your quiches.
- Stir in minced garlic and fresh thyme, cooking until fragrant, about 2 minutes. This is where your kitchen will start smelling amazing!
- Add the chopped spinach and cook, stirring constantly, until just wilted, about 2 minutes. Remove the skillet from heat and let the mixture cool slightly.
- In a large bowl, whisk together eggs, milk, Dijon mustard, salt, and pepper until well combined. Stir in the shredded Gruyère cheese.
- Add the cooled mushroom and spinach mixture to the egg mixture, stirring to combine everything evenly.
- Coat a standard 12-cup muffin tin with cooking spray. Divide the mixture among the prepared muffin cups, filling each about ¾ full.
- Bake the quiches, uncovered, for about 30 minutes or until they’re puffed and set in the center. They should be golden brown around the edges.
- Remove from the oven and let cool for 5 minutes before gently removing from the pan. Serve warm and enjoy!
Variations
These versatile mini quiches can be customized in countless ways to suit your taste preferences or what you have on hand:
- Cheese variations: Try swapping Gruyère for sharp cheddar, feta, or goat cheese for different flavor profiles.
- Vegetable additions: Add roasted red peppers, sun-dried tomatoes, or artichoke hearts for Mediterranean flair.
- Protein boost: Include cooked and crumbled bacon, diced ham, or smoked salmon for extra protein and flavor.

Ingredients
— The Veggies —
1 tablespoon olive oil
8 oz (225g) cremini or white button mushrooms, washed and sliced
1 small yellow onion, finely diced
2 cups fresh spinach, chopped (or ½ cup frozen spinach, thawed and squeezed very dry)
1 clove garlic, minced
Salt and black pepper to taste
— The Egg Base —
6 large eggs
½ cup milk (dairy or almond milk) or heavy cream for richness
½ cup shredded Swiss cheese, Gruyère, or Cheddar
¼ cup crumbled Feta cheese (optional)
Non-stick cooking spray (for the muffin tin)
Instructions
1. **Preheat:** Preheat your oven to 350°F (175°C). Generously grease a standard 12-cup muffin tin with non-stick cooking spray (or use silicone muffin liners for easy removal).
2. **Sauté Veggies (Crucial Step):** Heat the olive oil in a skillet over medium-high heat. Add the sliced mushrooms and diced onion. Sauté for 5–7 minutes until the mushrooms have released their moisture and are browned. *Note: If you skip this, your quiches will be watery.*
3. **Add Spinach:** Stir in the minced garlic and fresh spinach. Cook for 1–2 minutes until the spinach is wilted. Season with a pinch of salt and pepper. Remove from heat and let cool slightly.
4. **Whisk Eggs:** In a large bowl, whisk together the eggs, milk, and a pinch of salt and pepper until frothy and well combined.
5. **Assemble:** Divide the cooked vegetable mixture evenly among the 12 muffin cups. Sprinkle the shredded cheese (and feta, if using) over the veggies.
6. **Pour:** Carefully pour the egg mixture into each cup, filling them about ¾ of the way full. Do not overfill, as they puff up while baking.
7. **Bake:** Bake for 20–25 minutes, or until the centers are set and the tops are slightly golden.
8. **Cool:** Let the quiches cool in the pan for 5–10 minutes before running a butter knife around the edges to loosen and remove them.
Notes
Avoid Soggy Quiches: The most important step is sautéing the mushrooms first. Mushrooms hold a lot of water, and if you put them in raw, that water will release during baking and make your eggs soggy.
Storage: These store perfectly in the fridge for up to 4 days. Reheat in the microwave for 30 seconds.
Freezing: To freeze, wrap cooled quiches individually in plastic wrap and store in a freezer bag for up to 3 months.
Variations: Feel free to add cooked bacon, sausage crumbles, or bell peppers to the mix.
