The sharp cheddar cheese adds a delightful tang, and fresh herbs brighten the whole experience. Plus, the addition of heavy cream keeps the frittata remarkably moist.
Where other recipes may leave you with a dry or rubbery texture, this one ensures each bite is filled with creaminess.
The combination of sautéing the mushrooms and onions creates a rich base, while the bright freshness of the spinach takes it to another level. By integrating expert knowledge of flavor profiles and cooking techniques, this recipe is crafted to please even the pickiest eaters.
The Ingredients
Here’s a simple shopping list for your Spinach Mushroom Frittata:
- 2 tablespoons extra virgin olive oil
- 1 small yellow onion, finely chopped
- 2 garlic cloves, minced
- 8 oz cremini mushrooms, thinly sliced
- 4 cups fresh baby spinach leaves
- 8 large whole eggs
- ½ cup heavy cream
- 1 cup shredded sharp cheddar cheese
- ½ teaspoon sea salt
- ½ teaspoon freshly ground black pepper
- 1 teaspoon dried thyme
- 1 tablespoon chopped fresh chives
Make sure to have all these on hand for delicious results.

Instructions
Getting the frittata from your kitchen to your plate is straightforward. Here’s how:
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C). This ensures that the frittata cooks evenly.
Step 2: Sauté the Vegetables
In a large oven-safe skillet, heat the olive oil over medium heat. Add the chopped onion and cook until translucent, about 4 minutes. Then, toss in the minced garlic, stirring for about 30 seconds until fragrant.
Next, add the sliced mushrooms and sauté until they release their moisture and begin to brown. This should take about 5 minutes.
Step 3: Add Spinach
Now, fold in the baby spinach leaves. Cook for another 2-3 minutes, just until they wilt. Combine all the flavors well and season with salt and pepper.
Step 4: Prepare the Egg Mixture
In a separate bowl, whisk together the eggs, heavy cream, dried thyme, and chopped chives. Make sure everything is well combined and season with a pinch more of salt and pepper.
Step 5: Combine Mixtures
Once the spinach and mushrooms are cooked, pour the egg mixture over the sautéed vegetables in the skillet. Give it a gentle stir to evenly distribute.
Step 6: Add Cheese
Sprinkle the shredded cheddar cheese on top, allowing it to settle into the egg mix. This ensures melted goodness in every slice.
Step 7: Bake the Frittata
Transfer the skillet to the preheated oven. Bake for about 20-25 minutes, or until the eggs are set and the top is slightly golden.
Step 8: Cooling and Serving
Remove the frittata from the oven. Let it cool slightly for about 5 minutes before slicing. Serve warm or at room temperature.
Notes
Here are some special tips to elevate your cooking game:
- Let the Eggs Come to Room Temperature: This helps to create a fluffier texture during cooking.
- Use a Mixing Bowl with a Spout: This makes pouring the egg mixture over the vegetables a breeze.
- Don’t Rush the Sautéing: Take your time with the mushrooms and onions to develop deeper flavors.
- Stir Gently: When mixing the egg with veggies, stir gently to avoid breaking the yolks too much, promoting a nice uniform cooking.
- Garnish Well: Adding a sprinkle of fresh herbs after cooking enhances both appearance and taste, making it look extra appealing.

How Do You Store This Spinach Mushroom Frittata?
To keep your frittata fresh, store leftovers in an airtight container in the fridge. It lasts for about 3-5 days.

Sides for Spinach Mushroom Frittata
Accompany your frittata with these delightful sides to round out your meal.
1. Fresh Arugula Salad
A simple salad of arugula dressed in olive oil and lemon juice provides a refreshing counterpoint to the frittata. The peppery bite of arugula complements the earthiness of spinach and mushrooms.
2. Roasted Tomatoes
Roast cherry tomatoes drizzled with olive oil and seasoned with salt. Their sweetness enhances the dish’s flavors. Plus, they add a vibrant pop of color to your plate.
3. Yogurt Dip
A sour cream or Greek yogurt dip mixed with herbs makes an excellent addition. The creaminess balances the frittata’s richness, introducing a refreshing element.

What Alternatives Can You Use for the Ingredients If They Are Not Present in Your Kitchen?
It’s good to have alternatives in your back pocket!
1. Cheese:
If cheddar isn’t available, try feta for a tangier flavor or mozzarella for a milder, gooey texture.
2. Cream:
You can substitute heavy cream with half-and-half or even yogurt for a lighter option, though the texture will change slightly.
3. Spinach:
In case you’re out of spinach, kale or Swiss chard are excellent replacements, offering similar nutrients and taste profiles.
4. Eggs:
For a vegan option, mash silken tofu and season well, or use a commercial egg substitute to mimic the texture. Whipping in a bit of nutritional yeast can add a cheesy flavor.
