Ingredients You’ll Need For This Spinach and Vegetables Frittata
For the frittata:
- 8 large eggs
- ยผ cup whole milk or cream
- 3 cups fresh spinach (loosely packed)
- 1 red bell pepper, diced
- 1 cup mushrooms, sliced
- ยฝ red onion, finely chopped
- ยพ cup shredded cheddar cheese (or your favorite)
- 2 tablespoons olive oil
- 1 teaspoon salt
- ยฝ teaspoon black pepper
- ยฝ teaspoon garlic powder
- Fresh herbs (dill, parsley, or chives โ optional but recommended)

Step-by-Step Instructions
Preparation Phase
Step 1: Preheat Your Oven
Start by preheating your oven to 375ยฐF (190ยฐC). This gives it time to reach the perfect temperature while you prep everything else.
Step 2: Prepare Your Vegetables
Dice your red bell pepper into small, even pieces. Slice the mushrooms. Chop your red onion finely. The smaller your cuts, the more evenly everything cooks. Trust me on this.
Step 3: Mix Your Egg Base
In a large bowl, crack all 8 eggs. Add the milk, salt, pepper, and garlic powder. Whisk everything together until the mixture is smooth and well combined. Don’t overmix, you want it blended but still light and airy.
Cooking Phase
Step 4: Sautรฉ Your Vegetables
Heat olive oil in a 10-inch oven-safe skillet over medium heat. Add your diced onion first, it needs a bit more time. Cook for about 2 minutes until it starts to soften.
Add the bell pepper and mushrooms. Stir occasionally and cook for another 3-4 minutes. You want the vegetables tender but still with a bit of texture.
Step 5: Add the Spinach
Toss in your fresh spinach. It’ll look like a lot at first, but don’t worry, it wilts down quickly. Stir until the spinach is completely wilted and any excess moisture has evaporated. This takes about 2 minutes.
Step 6: Pour the Egg Mixture
Reduce the heat to medium-low. Pour your whisked egg mixture evenly over the vegetables. Gently stir to distribute the veggies throughout the eggs. Let it cook undisturbed for about 2-3 minutes until the edges start to set.
Step 7: Add the Cheese
Sprinkle your shredded cheese evenly over the top. If you’re using fresh herbs, add them now too. The heat will bring out their amazing flavors.
Step 8: Transfer to the Oven
Once the edges are set but the center still looks slightly wet, carefully transfer your skillet to the preheated oven. Bake for 12-15 minutes until the center is just set and the top is lightly golden.
Step 9: Cool and Serve
Remove from the oven and let it cool for 2-3 minutes. This makes it easier to slice and serve. Cut into wedges and enjoy immediately.

Pro Tips for the Perfect Spinach and Vegetables Frittata
Use an Oven-Safe Skilletย
This is non-negotiable. Your skillet needs to go from stovetop to oven without any issues. Cast iron or stainless steel work beautifully.
Don’t Overcook the Eggs
The frittata continues cooking after you remove it from the oven. Pull it out when the center is just barely set. It’ll firm up as it cools, and you’ll have a perfectly creamy texture.
Prep Your Vegetables in Advance
Chop everything the night before. Store in separate containers in your fridge. In the morning, you’re literally just cooking and assembling.
Experiment with Vegetables
Love broccoli? Add it. Prefer zucchini? Go for it. Craving sun-dried tomatoes? Absolutely. A spinach and vegetables frittata is incredibly flexible.
Make It Dairy-Free
Swap the milk for almond milk or oat milk. Use dairy-free cheese or skip it entirely. The frittata still turns out delicious.
Serving Suggestions
Serve your spinach and vegetables frittata warm or at room temperature. It’s perfect with a simple green salad and crusty bread. A dollop of sour cream or Greek yogurt on top adds a nice tang.
For brunch, pair it with fresh fruit and mimosas. For dinner, serve alongside roasted potatoes or a grain like quinoa.
Storage and Leftovers
This frittata stores beautifully. Keep leftovers in an airtight container in the fridge for up to 4 days. Reheat gently in a 350ยฐF oven for about 10 minutes, or enjoy it cold straight from the fridge.
You can also freeze it. Wrap individual slices in plastic wrap and aluminum foil. They’ll keep for up to 3 months. Thaw overnight in the fridge before reheating.
