🥣 Instructions
Follow these easy steps for a perfect Mushroom & Spinach Frittata:
Step 1: Preheat & Prep
-
Preheat your oven to 375°F (190°C), or turn your broiler on high if using a stovetop-to-oven method.
-
Crack eggs into a mixing bowl, add milk, salt, pepper, and garlic powder. Whisk well until light and frothy. Set aside.
Step 2: Cook Vegetables
-
Heat the olive oil in an oven-safe skillet over medium heat.
-
Add the diced onions and sauté for 2-3 minutes until translucent.
-
Add sliced mushrooms and cook for another 4-5 minutes until browned and tender. Stir occasionally.
-
Toss in chopped spinach and cook for 1-2 minutes until wilted.
Step 3: Add Egg Mixture
-
Lower the heat to medium-low.
-
Pour the egg mixture evenly over the sautéed veggies.
-
Gently stir with a spatula to ensure even distribution.
-
If you’re adding cheese, sprinkle it on top now.
Step 4: Cook Until Set
-
Let the frittata cook on the stovetop for 5-6 minutes, until the edges start to set but the center remains slightly jiggly.
Step 5: Transfer to Oven
-
Carefully transfer the skillet to the preheated oven or place under the broiler for 5-8 minutes.
-
Bake until the top is golden and fully set. Check with a knife inserted into the center; it should come out clean.
Step 6: Rest and Serve
-
Remove from oven and let rest for 5 minutes.
-
Garnish with fresh herbs if desired.
-
Slice into wedges and serve warm or at room temperature.
💡 Tips for Success
-
Use fresh spinach instead of frozen to avoid excess moisture.
-
Pre-cook vegetables thoroughly to avoid a watery frittata.
-
Don’t overbake—this can lead to a rubbery texture.
-
Use a well-seasoned cast-iron skillet or nonstick pan to prevent sticking.

❄️ How to Store and Reheat
-
🧊 Store: Let the frittata cool completely. Store in an airtight container in the fridge for up to 4 days.
-
🔥 Reheat: Microwave individual slices for 30-60 seconds or warm in the oven at 300°F for 10 minutes.
