For the Vegetable Filling

  • Olive Oil: Used for sautéing the vegetables to bring out their flavor.
  • Mushrooms: Cremini or button mushrooms work perfectly. Make sure to chop them finely.
  • Spinach: Fresh spinach is essential. We’ll cook it down to remove excess water.
  • Garlic & Onion Powder: These add a deep, savory base flavor that complements the eggs and cheese perfectly.

For the Egg Mixture

  • Large Eggs: The foundation of our quiche muffins.
  • Milk or Heavy Cream: For a richer, more traditional quiche texture, use heavy cream. For a lighter version, milk works wonderfully.
  • Cheddar Cheese: Sharp cheddar provides the best flavor, but feel free to substitute with Gruyère, Swiss, or Feta.
  • Salt & Black Pepper: To season the egg mixture.

Step-by-Step Instructions for Perfect Spinach and Mushroom Quiche Muffins

Follow these simple steps to guarantee fluffy, golden-brown quiche muffins every time. The most critical part is cooking the moisture out of the spinach and mushrooms before baking.

Step 1: Prepare the Vegetables

Preheat your oven to 375°F (190°C) and grease a 12-cup muffin tin generously. In a large skillet over medium heat, add the olive oil. Once warm, add the chopped mushrooms and cook until they have released their water and started to brown, about 5-7 minutes. Add the fresh spinach and cook, stirring frequently, until it has completely wilted and the excess moisture has evaporated. This step is crucial to prevent soggy muffins. Stir in the minced garlic, onion powder, salt, and pepper, and cook for another minute until fragrant. Remove from heat and set aside.

Step 2: Mix the Egg Base

In a large bowl, whisk the eggs until the yolks and whites are fully combined. Slowly whisk in the milk or heavy cream until the mixture is smooth. Stir in about three-quarters of the shredded cheddar cheese, reserving the rest for topping.

Step 3: Assemble and Bake

Divide the cooked spinach and mushroom mixture evenly among the 12 greased muffin cups. Carefully pour the egg mixture over the vegetables in each cup, filling them about three-quarters full. Sprinkle the remaining cheddar cheese on top of each muffin. Bake for 20-25 minutes, or until the centers are set and the tops are lightly golden brown. Let them cool in the tin for a few minutes before running a knife around the edges and removing them.

Pro Tips for Quiche Success

Want to ensure your Spinach and Mushroom Quiche Muffins are bakery-quality? Follow these expert tips.

  • Don’t Skip Sautéing: Squeezing the water out of your vegetables after cooking is the number one secret to avoiding a watery, spongy quiche.
  • Grease the Pan Well: Use butter, oil, or a non-stick spray and be generous. This ensures your mini quiches pop right out.
  • Don’t Overbake: The muffins will continue to cook slightly from residual heat after you remove them from the oven. Pull them out when the center is just set.

Delicious Variations to Try

This recipe is a wonderful template. Feel free to get creative with your add-ins!

  • Add Meat: Crumbled bacon, cooked sausage, or diced ham are excellent additions.
  • Change the Cheese: Try feta for a salty, tangy flavor, or Gruyère for a nutty, classic taste.
  • More Veggies: Diced bell peppers, onions, or even some of the ingredients from our popular sautéed zucchini and mushrooms would be delicious.

Storage, Freezing, and Reheating Instructions

One of the best things about these quiche muffins is how well they store. They are a meal-prepper’s dream come true.

Storing

Allow the muffins to cool completely, then store them in an airtight container in the refrigerator for up to 4 days.

Freezing

Once completely cool, place the muffins on a baking sheet and flash-freeze for about an hour. Transfer the frozen muffins to a freezer-safe zip-top bag or container. They can be stored in the freezer for up to 3 months.

Reheating

You can reheat the muffins in the microwave for 30-60 seconds or in a toaster oven at 350°F (175°C) for about 10 minutes until warmed through.

Frequently Asked Questions

This is a crustless recipe, which makes it quicker, easier, and lower in carbs. They hold together perfectly without a crust thanks to the egg and cheese.

The key is to remove as much moisture as possible from the vegetables before adding them to the egg mixture. Sauté the mushrooms until they release their liquid and cook the spinach until it’s completely wilted and the pan is dry.

For best results, reheat them in a toaster oven or air fryer at 350°F (175°C) for 8-10 minutes. You can also microwave them for 30-60 seconds, but the texture will be softer.

Sharp cheddar is fantastic for its flavor, but Gruyère, Swiss, Monterey Jack, and feta are also excellent choices. A combination of cheeses can also be delicious.

Ingredients
  

  • 1 tbsp Olive Oil
  • 8 oz Cremini Mushrooms finely chopped
  • 5 oz Fresh Spinach
  • 2 cloves Garlic minced
  • 1/2 tsp Onion Powder
  • 10 Large Eggs
  • 1/2 cup Milk or Heavy Cream

Equipment

  • 1 12-cup muffin tin
  • 1 Large Skillet
  • 1 Large Mixing Bowl

Method
 

  1. Preheat your oven to 375°F (190°C). Generously grease a 12-cup standard muffin tin with butter or non-stick spray.
  2. Heat olive oil in a large skillet over medium heat. Add the chopped mushrooms and cook for 5-7 minutes until they release their moisture and begin to brown. Add the fresh spinach and cook until fully wilted and all excess water has evaporated. Stir in the minced garlic, onion powder, salt, and pepper, cooking for one more minute until fragrant.

  6. Let the quiche muffins cool in the tin for 5-10 minutes before carefully removing them. Serve warm or allow to cool completely for storage.

Notes
