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.

- Ham
- Bacon
