Do you ever have those moments where you need a solid breakfast or brunch dish to serve, but have NO IDEA what to make? I am solving your problem with this easy baked frittata recipe with spinach, and all the good greens! It's also gluten-free, baked in a 9x13 pan, and is ready in under an hour. (Your in-laws and brunch guests will be so impressed!)

Materials needed for this easy baked frittata recipe

First and foremost, you need a quality 9x13 baking dish. I liked my cast iron pan because it bakes beautifully and looks nice for your brunch tablescape.
No frittata dish is complete without some beautiful leafy greens, so make sure you have quality power greens. When I'm in a pinch on time, or don't have fresh greens available, I use a prepackaged salad blend. However, any good mix of spinach, lettuces, chard, arugula, and herbs like cilantro, parsley, and dill will work beautifully! Your frittata looks really pretty with all of the color, and adding greens is a great way to make it a healthy brunch dish that is full of vitamins and nutrients.
Make sure you buy a dozen eggs for this recipe! It calls for all 12, and you want to have enough for other items too.

How to lock in flavor in a baked frittata

There are three key ingredients that you must not skip to ensure a mind-glowingly delicious meal!

Herbs - Absolutely use basil! I also love parsley. They both provide that robust taste that pairs well with the savory factor.
Parmesan - Get a high quality block of parmigiano reggiano , that you grate yourself, if possible. This gives is the richest and deepest flavor.
Salt. I always opt for pink Himalayan salt, because it is rich in mineral content that can help balance your body’s pH levels. This is important because your pH needs a healthy acid-to-alkaline ratio, to ensure optimal health. A proper pH also helps support your immunity, supports healthy thyroid function, and encourages good digestion (source). Since pink Himalayan salt contains sodium as well as other electrolytes, it has a direct effect on the pH of your blood.

If you don't have these, your frittata will be bland, so don't skimp on this part! You MUST use fresh basil and fresh parmesan cheese in this recipe. TRUST ME.

How to make an easy baked frittata with spinach, step-by-step

Cook veggies in avocado oil on medium heat, until fragrant and translucent (step 1). In a separate bowl, whisk eggs until light and fluffy, and add milk, cheese, and seasonings (step 2). Fold in mixed greens and herbs (step 3). Pour all ingredients into a 9x13 baking dish and stir. Top with parmesan cheese and cook on 350 degrees Fahrenheit until internal temp is 160 degrees Fahrenheit and frittata is set in the middle.

Tips to prevent frittata being runny or watery

There are a couple of things you DON'T want to happen when making a frittata:

Runny, watery frittata
Middle of the frittata not cooking
Frittata isn't setting

These are all the most common problems people run into when making this spectacular egg dish. But with this recipe, you won't have that issue! You know your frittata is done when internal temp is 160 degrees Fahrenheit, and the middle doesn't jiggle when removed from oven.

Bake it in a heavy 9x13 baking dish. This ensures even heat distribution and best results.
Bake until internal temp is at least 160 degrees F, which is the recommended time for eggs. On my oven, this is at least 50 minutes (depending on your altitude and oven).
Let it set for 10-15 minutes. THIS IS IMPORTANT!

These three steps will give you the perfect, fool-proof consistency every time.
