Spinach And Mushroom Quiche Muffins are my favorite answer to those mornings when you want something warm and filling, but you do not want to cook a whole big breakfast. I started making them when I got tired of grabbing random snacks and calling it a meal. These little quiche cups feel kind of fancy, but honestly they are super simple. They are also great when you need a quick lunch, a protein snack, or something easy to bring to a brunch. And the best part is they reheat like a dream, so you can make a batch and feel very prepared all week.
What Ingredients Do You Need for Spinach Quiche?
Let us keep this real and doable. I am not trying to send you on a scavenger hunt for rare ingredients. This is mostly stuff you can find at any grocery store, and you might already have a bunch of it at home.
My go to ingredient list
- Eggs: 8 large eggs for a standard 12 muffin tin batch
- Milk: 1 third cup, any kind you like (dairy or unsweetened non dairy)
- Cheese: 1 cup shredded (cheddar, mozzarella, Swiss, or a mix)
- Spinach: 2 cups fresh chopped, or 1 cup frozen thawed and squeezed dry
- Mushrooms: 1 cup chopped (white button or baby bella are perfect)
- Onion: 1 small, finely chopped (or 2 to 3 tablespoons green onion)
- Garlic: 1 to 2 cloves minced, optional but highly recommended
- Salt and pepper: start with 1 half teaspoon salt and a good pinch of pepper
- Optional extras: pinch of red pepper flakes, paprika, or a little dried thyme
- Oil or butter: for cooking the veggies and greasing the pan
If you love the spinach plus egg combo as much as I do, you might also enjoy this brunchy recipe for later: savory smoked salmon and spinach quiche. It is a little more weekend style, while these muffins are more everyday friendly.
How to Prepare Spinach Quiche Muffins/Cups?
These Spinach And Mushroom Quiche Muffins are basically a stir, sauté, and bake situation. Nothing complicated, but a few small steps make them come out fluffy instead of watery. You will want a muffin tin, a mixing bowl, and a skillet for the mushrooms.
Simple step by step directions
1) Heat the oven and prep the pan. Set your oven to 350 F. Grease a 12 cup muffin tin really well. I am serious about this. Eggs love to cling to muffin tins like it is their hobby. If you have silicone liners, those work great too.
2) Cook the mushrooms and onion. Warm a little oil or butter in a skillet over medium heat. Add chopped mushrooms and onion with a pinch of salt. Cook for about 6 to 8 minutes until the mushrooms release their liquid and it mostly cooks off. Add garlic in the last 30 seconds so it does not burn.
3) Deal with the spinach. If you are using fresh spinach, toss it into the skillet for 1 to 2 minutes just until wilted, then take it off the heat. If you are using frozen spinach, squeeze out as much water as you can. This one step is the difference between nice quiche cups and soggy ones.
4) Mix the egg base. In a bowl, whisk the eggs with milk, salt, pepper, and any seasonings you like. Whisk until the mixture looks smooth and a little frothy.
5) Add cheese and fillings. Stir in cheese, then fold in the cooked mushroom mixture and spinach. I like mixing everything in the bowl so each muffin ends up with a fair amount of filling.
6) Fill the muffin cups. Pour the mixture into the muffin tin, filling each cup about three quarters full. They puff up a bit as they bake.
7) Bake. Bake 18 to 22 minutes, until the centers look set and a toothpick comes out clean. Let them cool in the pan for about 5 minutes, then run a butter knife around the edges and lift them out.
Quick note on doneness: If the tops look lightly golden and the middle does not jiggle much, you are good.
Sometimes I serve these with a quick sauce on the side, even just warm marinara. If you want a solid homemade option, I have been using this one a lot: delicious and easy homemade marinara sauce. It makes the muffins feel extra cozy.
I made these for a work breakfast and they disappeared fast. Even the people who said they do not like spinach grabbed seconds. They were fluffy, not watery, and tasted great the next day too.
Nutritional Information for Spinach Quiche
I am not a dietitian, but I can tell you what you are generally getting with these. Spinach And Mushroom Quiche Muffins are naturally packed with protein from the eggs, plus fiber and nutrients from the veggies. They are also a nice option when you want something low in sugar and more balanced than a pastry.
Here are the main nutrition highlights in plain language:
Protein: Eggs and cheese bring solid staying power, which is why one or two muffins can actually hold you over.
Veggies: Spinach adds iron, folate, and vitamin K. Mushrooms add B vitamins and a savory flavor that makes everything taste more satisfying.
Carbs: Very low, since there is no crust. That is handy for anyone cutting back on bread or just trying to add more protein to breakfast.
Calories: It depends on your cheese and milk. Using reduced fat cheese or less cheese lowers it. Adding extra cheese or bacon raises it, which is not a bad thing if you need something more filling.
If you are tracking, the easiest way is to plug your exact ingredients into your favorite nutrition calculator. I do that when I am adjusting recipes for the week, especially if I am swapping cheeses or using a different milk.
Tips for Perfect Spinach Quiche Muffins/Cups
This is the section I wish someone had handed me the first time I made egg muffins. They are easy, but a few tiny details make them go from just fine to honestly great.
Get the moisture out. Mushrooms and spinach both hold a lot of water. Cook mushrooms until their liquid evaporates. If using frozen spinach, squeeze it like you mean it.
Grease the pan well. Even nonstick pans can stick with eggs. Oil spray, butter, or silicone liners will save your day.
Do not overbake. Overbaked egg muffins get rubbery. Pull them when the center is just set.
Let them cool a few minutes before removing. They firm up as they cool, so they pop out cleaner.
Storage and reheating. Store in the fridge for up to 4 days. Reheat 15 to 25 seconds in the microwave for one muffin, or a bit longer for two. If you want a slightly crisp edge, reheat in the oven or air fryer at 325 F for a few minutes.
Freezing tip. Freeze them on a plate first, then move to a freezer bag. That way they do not stick together in one big block.
Common Substitutions for Ingredients
I love recipes that can bend based on what is in the fridge. Spinach And Mushroom Quiche Muffins are perfect for that. Here are swaps that still work really well.
Spinach: Try kale (chopped small and sautéed), Swiss chard, or even leftover roasted broccoli chopped up.
Mushrooms: If you are not a mushroom person, swap in diced bell pepper, zucchini (cook it first to dry it out), or cooked asparagus tips.
Cheese: Feta gives a salty tang. Swiss makes it taste like a diner omelet. Pepper jack adds a little kick.
Milk: Whole milk makes them richer. Unsweetened almond milk works fine too. Heavy cream is delicious, but it makes them heavier.
Add ins: Cooked bacon, diced ham, or sausage are all great. Just make sure anything meaty is cooked first and drained well.
Dairy free idea: Use unsweetened non dairy milk and either skip cheese or use a dairy free shred that melts well. The texture is a bit different but still tasty.
Common Questions
Can I make Spinach And Mushroom Quiche Muffins ahead of time?
Yes, and that is honestly when they shine. Make them Sunday, then grab and reheat all week.
Why did my egg muffins turn out watery?
Usually it is moisture from frozen spinach or mushrooms. Squeeze spinach dry and cook mushrooms long enough to evaporate their liquid.
How do I keep them from sticking to the muffin tin?
Grease the pan generously and let them cool for a few minutes before removing. Silicone liners are the easiest solution if you have them.
Can I make these without cheese?
Yes. They will be a little less rich, but still good. Add extra seasoning, and consider a spoonful of chopped herbs for flavor.
How many should I serve per person?
For breakfast, I plan on 2 muffins per adult. For brunch with other dishes, 1 per person is usually enough.
