I love making this mushroom spinach frittata because it’s a simple way to enjoy a healthy meal any time of day. It’s packed with fresh veggies and feels like a warm hug on a plate. I think you’ll enjoy how easy it is to make and how tasty it turns out!
Most of the ingredients in this recipe are easy to find in any kitchen or grocery store. If you don’t usually keep fresh spinach or mushrooms at home, you can find them in the produce section of your supermarket. Fresh spinach is usually sold in bags or bunches, and mushrooms come pre-sliced or whole. The cheese is optional, so you can skip it if you don’t have any or want to keep it dairy-free.
Ingredients For Mushroom Spinach Frittata Recipe
Eggs: The main ingredient that holds the frittata together and gives it a fluffy texture.
Mushrooms: Adds a savory, earthy flavor and soft texture when cooked.
Spinach: Fresh spinach adds a mild, slightly sweet taste and lots of color.
Cheese: Optional, but adds creaminess and a little extra flavor on top.
Olive oil: Used to cook the mushrooms and spinach without sticking.
Salt: Enhances all the flavors in the dish.
Black pepper: Adds a little bit of spice and depth to the taste.
Technique Tip for This Recipe
One of the most helpful moves in this Mushroom Spinach Frittata Recipe is how you whisk the eggs with the salt and pepper. Whisking might seem simple, but doing it right makes a big difference in how fluffy and smooth your frittata turns out.
Here’s a quick way to whisk without making a mess or leaving lumps:
- Crack all your eggs into a clean bowl before adding anything else.
- Add the salt and pepper right on top.
- Hold your whisk like a pencil, and start moving it in small circles or figure eights.
- Keep whisking until the mixture looks a little frothy and all the yolks and whites are fully mixed together.
- If you want, you can lift the whisk out of the bowl now and then to check if the eggs are smooth and even.
Doing this helps the eggs mix well with the seasoning and lets air get in, which makes the frittata lighter and fluffier when it cooks. If you don’t whisk enough, you might end up with a dense or uneven texture, which isn’t as tasty.
I remember the first time I made a frittata, I didn’t whisk long enough and got some big clumps of yolk that didn’t cook right. After that, I made sure to whisk just a bit longer, and it made all the difference. Plus, if you’re in a hurry, you can use a fork instead of a whisk—it won’t be quite as smooth, but it still works fine!
Whisking well is a small step that really helps your Mushroom Spinach Frittata come out just right every time.

How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover frittata on a baking sheet and cover it with aluminum foil to prevent it from drying out. Heat for about 10-15 minutes or until warmed through.
For a quicker method, use the microwave. Place a slice of the frittata on a microwave-safe plate. Cover it with a damp paper towel to retain moisture. Heat on medium power for 1-2 minutes, checking halfway through to ensure it heats evenly.
If you prefer a slightly crispy texture, reheat the frittata on the stovetop. Heat a non-stick skillet over medium heat and add a small amount of olive oil. Place the slice in the skillet and cover with a lid. Heat for about 3-5 minutes, flipping halfway through.
For those with an air fryer, preheat it to 300°F (150°C). Place the frittata slice in the basket and heat for about 5-7 minutes. This method will give you a nice, slightly crispy edge.
If you have a toaster oven, preheat it to 350°F (175°C). Place the frittata slice on a piece of aluminum foil or a small baking sheet. Heat for about 10 minutes or until warmed through.
