Ingredients You’ll Need
These ingredients are straightforward but each plays an essential role in delivering the perfect balance of taste, texture, and color for your Mushroom and Spinach Frittata Recipe. From the earthy mushrooms to the fresh greens and creamy cheese, every component works harmoniously.
- 8 large eggs: The star providing structure and richness to the frittata.
- 1/4 cup milk: Adds creaminess and helps create a tender, fluffy texture.
- 1/2 teaspoon salt: Enhances all the natural flavors without overpowering them.
- 1/4 teaspoon black pepper: Offers just a hint of warmth and subtle spice.
- 1 tablespoon olive oil: Used for sautéing to lend a beautiful golden color and slight fruitiness.
- 1/2 small onion (diced): Provides a sweet and savory base note.
- 2 cups sliced mushrooms (cremini or button): Brings an earthy depth with a satisfying meaty texture.
- 2 cups fresh spinach (roughly chopped): Adds vibrant green color and a mild, fresh flavor.
- 1/2 cup shredded cheese (cheddar, mozzarella, or feta): Melts into gooey goodness, giving richness and a mild tang.
- Chopped fresh parsley or chives for garnish (optional): Adds a final fresh brightness and prettiness.
How to Make Mushroom and Spinach Frittata Recipe
Step 1: Whisk Together the Eggs and Seasonings
Begin by cracking those eggs into a medium bowl, then whisk together with the milk, salt, and black pepper. This simple mix forms the gorgeous custard base of your frittata, ensuring each bite is creamy and flavorful. Set this aside so you can focus on prepping the veggies.
Step 2: Sauté the Onions and Mushrooms
Heat the olive oil over medium heat in a 10-inch oven-safe skillet, then toss in your diced onions. Cooking them gently softens their sweetness and creates a wonderful fragrant base. Next, add in the mushrooms and let them brown beautifully. This step unlocks their savory, umami magic that will elevate your frittata.
Step 3: Wilt the Spinach
Add the fresh spinach directly to the pan with your mushrooms and onions. It will seem like a lot at first, but spinach wilts quickly, releasing moisture and melding all the flavors together. Stir just until it softens, making sure every bite has that fresh, green goodness.
Step 4: Combine Egg Mixture and Vegetables
Evenly spread your cooked veggies across the skillet, then pour the whisked eggs over them. The eggs will settle perfectly around the mushrooms and spinach, wrapping everything in silky goodness.
Step 5: Sprinkle on the Cheese
Generously sprinkle the shredded cheese over the surface. This is the moment the frittata starts transforming into a rich, savory delight as the cheese melts and browns in the oven.
Step 6: Cook on Stovetop Before Baking
Let the skillet cook on the stovetop for about 2–3 minutes to help the edges begin to set. This step aids in creating a nice crust that holds the frittata together beautifully.
Step 7: Bake Until Fully Set
Transfer your oven-safe skillet to the preheated oven and bake for 10–12 minutes. Keep an eye as the top becomes slightly golden and the center firms up, signaling that your frittata is ready for slicing and serving.
Step 8: Cool Slightly and Garnish
Once out of the oven, let the frittata cool for a few minutes to allow the flavors to settle and make slicing easier. Garnish with fresh parsley or chives if desired—this final touch adds a hint of herbal brightness and makes the dish look as amazing as it tastes.

Garnishes
Fresh herbs like parsley or chopped chives are perfect garnishes, adding liveliness and color that brighten every slice. A light sprinkle of cracked black pepper or a dash of paprika can also add a little visual and flavor punch.
Side Dishes
This Mushroom and Spinach Frittata Recipe pairs beautifully with crisp mixed greens tossed in a vinaigrette for a refreshing contrast. You can also serve it alongside crusty bread or a fresh fruit salad to balance out the savory richness and make your meal feel like a true celebration.
Creative Ways to Present
Consider cutting the frittata into bite-sized squares for easy party appetizers or layering it in a clear baking dish to showcase its colorful layers. Drizzling with a bit of balsamic glaze or dolloping with a mild yogurt or sour cream can add an elegant twist that surprises and delights.
Make Ahead and Storage
Storing Leftovers
After enjoying your frittata, wrap any leftovers tightly in plastic wrap or place them in an airtight container. Stored in the refrigerator, it will stay fresh for up to 3 days, making it a fantastic option for quick breakfasts or lunches throughout the week.
Freezing
The Mushroom and Spinach Frittata Recipe freezes well. Slice it into portions and wrap each piece individually in foil or plastic wrap before storing them in a freezer-safe bag. This way, you can enjoy homemade goodness even on the busiest days by simply reheating.
Reheating
To reheat, gently warm your frittata slices in a microwave or oven until heated through. Oven reheating at 350°F for about 10 minutes helps maintain the best texture and flavor without drying it out. This makes it incredibly convenient to enjoy anytime.
