🥣 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.

🍽 Serving Suggestions

Pair your Mushroom & Spinach Frittata with:

• A side of roasted potatoes or hash browns

• Whole-grain toast or sourdough

• A simple arugula or tomato salad

• Greek yogurt and fruit for a balanced brunch

❄️ 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.

• ❌ Avoid: Freezing, as the texture may become rubbery after thawing.
