Eggs are definitely my go-to breakfast as of late. I’ve discovered that having a good amount of protein and healthy fats is my best defense for late-day snacking. One of my favorite ways to enjoy eggs is with veggies and a bit of cheese.

This Spinach & Mushroom Frittata is amazing. It’s incredibly healthy, loaded with protein and a fantastic make-ahead breakfast for busy mornings or when you want to take breakfast to work.

Here’s the simple steps in making this Baked Spinach & Mushroom Frittata

Step 1: Choose your ingredients for your Baked Frittata

For my healthy baked frittata, I went with some simple vegetables, primarily spinach, mushrooms, red onions and red pepper. Feel free to change these up this vegetable combination if you want to substitute for what you already have in your refrigerator.

You’ll also need a dozen eggs, a bit of milk and cheese. If you need your frittata to be diary-free, you can omit the milk and cheese.

Step 2: Saute the vegetables

In a cast-iron skillet (or any other medium-sized skillet) saute the vegetables in a bit of olive oil. Pre-cooking the vegetables simply helps speed up the baking process once the frittata goes into the oven.

This is also a good time to preheat your oven.

Step 3: Whisk together the eggs

While your vegetables are sautéing, whisk together the dozen eggs along with the milk. Add salt and pepper to taste. For me this is several grinds of my salt and pepper grinders.

Step 4: Pour the whisked eggs into the skillet with the vegetables

Once your vegetables are cooked and slightly softened, you can pour the eggs right into the cast iron skillet.

Top the eggs & vegetables with the cheese of your choice. For this recipe, I’m using a shredded cheddar jack blend, but I also really love goat cheese in this delicious mushroom frittata.

What other cheese can I add to this frittata?

  • Goat Cheese
  • Gorgonzola
  • Blue Cheese
  • Shredded Parmesan
  • Shredded Mozzarella

Next, bake for approximately 25 minutes or until the center is mostly firm when you giggle the skillet.

Frequently Asked Questions about How to Make a Frittata:

Can I bake this frittata in a baking dish?

  • Yes, absolutely! If you don’t have a cast iron skillet, you can bake this frittata in a pie plate or baking dish. You can either saute the vegetables in a separate skillet OR add the raw vegetables directly to the baking dish. You will need to bake the frittata for an additional 5-10 minutes if you’re not pre-cooking the vegetables.

I want to add extra protein to this frittata? What other protein options can I add?

  • Ham
  • Bacon
  • Sausage or Chorizo
  • Turkey or Chicken Sausage

How do I meal prep this frittata and keep it healthy?

Slice this spinach and mushroom frittata into six slices and add to your favorite meal prep containers. I like to pair my baked frittata with fresh fruit.

FAQs

How do you keep frittata fluffy? ›

Tips for Fluffy Eggs

You can add up to 1/2 cup per dozen eggs. Don't overcook! Overcooking eggs makes them rubbery. When you remove the Frittata from the oven, it will continue to cook, especially if you are using cast iron, which retains heat well.

How do you know when to flip a frittata? ›

Replace cover on the skillet, reduce heat to medium-low, and cook until the egg is lightly browned on the bottom, 3 to 5 minutes. Carefully flip the frittata and cook until the bottom is again lightly browned, 1 to 2 minutes more.

How do you make frittata not watery? ›

If the center is still liquid, you've got to cook longer. If it's almost set, cook the frittata a few more minutes, then remove it.

Do you add milk to frittata? ›

Frittatas are so simple to make! Here's how: Choose a recipe variation below, and start by whisking together the frittata base: a simple mixture of eggs, almond milk (or any milk), garlic, salt, and pepper. Then, sauté your veggies in a 10 or 12-inch cast iron skillet just until tender.

When making a frittata, which ingredient should be pre-cooked prior to adding it to the egg mixture? ›

Tough vegetables like potatoes, squash and onions need to be pre-cooked since they will not have time enough to soften before the eggs are done. Raw meats such as bacon and sausage also need more time and heat to cook through safely, so get them prepped before your other ingredients.

What is the frittata formula? ›

Easy Formula For a Frittata

6 eggs. 1/4 cup heavy cream. 1 cup cheese. 2 cups veggies and/or meat.

What kind of pan is best for frittata? ›

The food site also specifically recommends a properly seasoned cast iron skillet for this task. Not only will its all-metal construction make cooking in the oven a worry-free feat, but it will also add to the quality of the frittata.

How to tell if frittata is done? ›

The eggs should be cooked through, not runny and a knife should come out clean when inserted into the centre. You can also give the skillet a gentle shake to determine if it is done; a runny frittata will jiggle when you shake the skillet.

How do you keep frittata from burning on the bottom? ›

I keep a lower heat to try to keep the bottom from burning. I strongly suggest using a nonstick or well-seasoned cast iron pan (I LOVE this pan - crisps, frittatas, casseroles, the best)…or the whole thing can be baked in a well greased, oven-proof dish.

How to fix a bland frittata? ›

Salt's the cure

Not only do you want to make sure to season your beaten eggs with a hefty dose of salt and pepper, but sprinkle the stuff on whatever fillings you pre-cook, too. More seasoning = maximum flavor.

What makes frittata spongy? ›

Dairy, like milk or cream, is a crucial component of frittatas. This is the ingredient that gives frittatas their signature creamy, fluffy texture. Without this important addition, frittatas cook up flatter and a bit more dense. Follow this tip: After whisking the eggs together, be sure to whisk in some milk or cream.

What to pair with frittata? ›

The best side dishes to serve with frittata are mixed green salad, garlic bread, waffles, cinnamon rolls, bagel bites, biscuits, potato rosti, roasted vegetables, fresh fruit salad, grilled asparagus, tomato and mozzarella salad, home fries, and quinoa tabbouleh.

Should you flip a frittata? ›

Pre-seasoning the eggs with salt helps them retain moisture during cooking. Cooking the vegetables in batches gives us more control over their texture. Keeping the cheese in large chunks gives us oozy pockets in the frittata. Flipping the frittata ensures a creamy, dense center.

What is a substitute for heavy cream in frittata? ›

Pour melted butter—which is essentially pure milkfat—into whole milk or even half-and-half, so that the mixture has a fat content similar to that of heavy cream. To make this two-ingredient heavy cream substitute, PopSugar recommends mixing ¾ cup of whole milk with ⅓ cup of melted and cooled butter.

What is the frittata ratio to memorize? ›

The egg to dairy ratio: If you are making a smaller frittata use 6 eggs and 1/4 cup of dairy, and if you are making a larger frittata use 12 eggs and 1/2 cup of dairy.

How do you keep frittata from going flat? ›

Forgetting to add milk or cream.

Without this important addition, frittatas cook up flatter and a bit more dense. Follow this tip: After whisking the eggs together, be sure to whisk in some milk or cream. As a rule of thumb, use 1/4 cup of dairy for every six eggs.

How do you keep eggs fluffy? ›

Add Moisture and Mix

Since dryness leads to dense, chewy eggs, this is a chance to boost your eggs with some extra moisture. Adding approximately 1 tablespoon of liquid per egg—milk or cream are delicious, but water works, too—will help create steam and keep the scrambled eggs moist.

Why did my frittata rise? ›

What Makes a Frittata Rise? Milk or cream is the essential ingredient that will make your frittata rise. Cooked without either milk or cream, the frittata will be flatter and less puffy. Add the milk or cream to the eggs and whisk them together until they are fluffy.
