Ingredients You’ll Need

• 8 large eggs
• 1/3 cup whole milk or half-and-half
• 5 ounces fresh baby spinach
• 1 medium shallot, diced
• 3/4 cup shredded cheddar cheese
• 1/4 cup grated Parmesan cheese
• 2 tablespoons olive oil
• 1/2 teaspoon kosher salt
• 1/4 teaspoon black pepper
• 1/4 teaspoon garlic powder (optional)

Ingredient Notes

Fresh Spinach: Baby spinach works best because it’s tender and wilts quickly. One 5-ounce container is perfect. Frozen spinach works too – thaw completely and squeeze out all the water first.

Cheese Selection: Sharp cheddar adds great flavor, but feel free to use Gruyere, Swiss, mozzarella, or feta. Mixing in Parmesan gives a nice nutty, salty kick.

Eggs and Dairy: Whole eggs create the best texture. The milk or cream makes the frittata tender and custardy. You can use 2 percent milk, but whole milk or half-and-half gives richer results.

Shallots vs. Onions: Shallots have a milder, sweeter flavor than regular onions. If you don’t have shallots, use half a small yellow onion instead.

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 350°F and place a rack in the upper third. Whisk together the eggs, milk, cheddar cheese, salt, and pepper in a large bowl until well combined. Set aside while you cook the vegetables.

Step 2: Cook the Shallots

Heat the olive oil in your oven-safe skillet over medium heat until shimmering. Add the diced shallot and cook, stirring often, until softened and translucent, about 3 to 4 minutes. Don’t let them brown.

Step 3: Wilt the Spinach

Add the spinach to the skillet one handful at a time, stirring as each batch wilts down. This takes about 2 to 3 minutes total. Let any water released from the spinach evaporate so your frittata doesn’t get watery.

Step 4: Add the Egg Mixture

Spread the spinach and shallots evenly across the bottom of the skillet. Pour the egg mixture over the vegetables, making sure it distributes evenly. Let it cook undisturbed for about 2 minutes until the edges just start to set. Sprinkle the Parmesan cheese over the top.

Step 5: Bake Until Set

Transfer the skillet to the preheated oven. Bake for 12 to 15 minutes until the frittata is puffed, golden, and set in the center. A toothpick inserted in the middle should come out clean. Let cool for 5 minutes before slicing into wedges.

Pro Tips & Cooking Hacks

• Wrap the skillet handle with foil as a reminder that it’s hot when you take it out
• Don’t overfill your skillet – leave about an inch of space at the top
• Let eggs come to room temperature for 15 minutes before whisking for fluffier results
• Add a splash of hot sauce to the egg mixture for a spicy kick
• Use a rubber spatula to gently lift the edges and let uncooked egg flow underneath

Tips & Variations

Add More Veggies: Toss in sautéed mushrooms, bell peppers, cherry tomatoes, or zucchini along with the spinach. Just make sure to cook out excess moisture first.

Meat Additions: Crumbled cooked bacon, diced ham, or crumbled sausage make this heartier. Add about 1/2 cup of cooked meat when you add the eggs.

Dairy-Free Version: Use olive oil or coconut milk instead of dairy milk, and skip the cheese or use dairy-free alternatives. It’ll be less rich but still delicious.

Fresh Herbs: Stir in chopped fresh basil, dill, or chives for extra flavor. Add them right before pouring the eggs into the skillet.

Serving Suggestions

Serve warm wedges with buttered toast, fresh fruit, and crispy bacon for a complete breakfast spread. A simple mixed green salad on the side makes it perfect for brunch.

Pair with roasted potatoes or hash browns for a heartier morning meal. The combination of crispy potatoes and creamy frittata is unbeatable.

For lunch or dinner, serve alongside a light soup or sandwich. Cold frittata wedges also make excellent packed lunch additions.

Common Mistakes

• Not squeezing water from frozen spinach – creates a watery frittata
• Cooking over too high heat – eggs scramble instead of setting smoothly
• Overbaking – pull it when just set, it continues cooking after removal
• Using a skillet that’s not oven-safe – always double-check your pan
• Forgetting the hot handle – seriously, use an oven mitt or wrap it in foil

What to Serve With Spinach Frittata

Classic breakfast sides like crispy bacon, sausage links, or breakfast potatoes round out the meal perfectly. Add fresh fruit or a berry smoothie for balance.

For brunch, set out a spread with pastries, muffins, yogurt parfaits, and mimosas. The frittata becomes the star protein that everyone can enjoy.

Make it a light dinner with crusty bread, a simple arugula salad, and a glass of white wine. The frittata is satisfying enough to be the main event.

Frequently Asked Questions

Can I make this ahead of time?

Yes! Bake it, let it cool completely, then cover and refrigerate for up to 4 days. Reheat individual slices in the microwave for 30 to 60 seconds.

Can I freeze leftover frittata?

Absolutely. Wrap cooled slices individually in plastic wrap, then store in a freezer bag for up to 3 months. Thaw overnight in the fridge before reheating.

What if I don’t have an oven-safe skillet?

Cook everything in a regular skillet, then transfer to a greased pie dish or baking dish before adding to the oven. Baking time may be slightly longer.

Can I use egg whites only?

You can, but the texture won’t be as rich and custardy. Use 12 to 14 egg whites to replace 8 whole eggs for best results.

How do I know when it’s done?

The frittata should be puffed and golden, with no liquid egg visible in the center. A toothpick inserted in the middle should come out clean or with just a few moist crumbs.
