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!

  1. Herbs - Absolutely use basil! I also love parsley. They both provide that robust taste that pairs well with the savory factor.
  2. Parmesan - Get a high quality block of parmigiano reggiano , that you grate yourself, if possible. This gives is the richest and deepest flavor.
  3. Salt. I always opt for pink Himalayan salt, because it isrich 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:

  1. Runny, watery frittata
  2. Middle of the frittata not cooking
  3. 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.

Serving Suggestions

I love to serve this baked frittata with a side of chocolate banana muffins, and a strawberry mango smoothie for the ultimate nourishing breakfast. And I also recommend these award winning gluten-free cinnamon rolls from This Vivacious Life.

    Can you bake this ahead and refrigerate it. And, preheat the next day when you're getting ready to eat?

    I made this for a potluck supper last night and everyone raved about it!

    There were a couple of small changes I made. I started by putting some thinly-sliced parcooked potatoes on the bottom of the 9x13 baking dish (which was coated with pan spray as instructed. Then I wilted my spinach and squeezed/drained as much moisture out of it, distributed it in the baking dish on top of the potato slices. I didn’t have any other greens, so I just did spinach. I only used fresh basil as an herb, but I think next time I will experiment with some others as well. Also, I used the whole milk option rather than the heavy cream.

    I generally use pastured eggs, so I couldn’t get the eggs to look “pale yellow” - those yolks are deep yellow, sometimes orange (full of omega-3s). But they lightened a little, and came out perfect. 😉

    I will make this one again and again! YUM. 😋

    This was so good, quick & easy and makes enough to share. Flavors mixed well. I forgot to add tomatoes so served some sliced on the side.
    I used a large onion, fresh chopped basil, and 3/4 Cup sour cream with 1/4 Cup of milk.
    I’m saving this recipe!!!!!

    Can you prepare this ahead of time and freeze until ready to eat?

    Reply

    • The Butter Half says

      Hey CJ! I have never tried to freeze it. However, in my experience, it keeps well in the refrigerator and develops flavor for up 5 days. I recommend prepping it ahead of time that way. I am not sure the eggs would hold and reheat well after being frozen.

FAQs

How do you keep frittata moist? ›

Adding a bit of dairy, whether it's cream or thick yogurt, is essential for getting the moisture and creaminess of the frittata just right. For every dozen eggs, use a half cup of dairy.

What size pan is best for frittata? ›

It's important to pull it from the oven before it's completely finished. The size of your pan is important- general rule of thumb- a 12 egg frittata should ideally be cooked in a 11-inch pan, a 6 egg frittata should be cooked in a 9-inch pan.

Does frittata contain gluten? ›

In its simplest explanation, a frittata is an egg dish that is similar to an omelet or quiche without a crust (hello gluten free).

Does frittata need cream? ›

I've had great results with heavy cream, half-and-half and whole milk. Sour cream, crème fraîche and yogurt will work as well. However, two percent and skim milk are too watery. Omitting the dairy altogether results in a frittata that is, unsurprisingly, more eggy in flavor and less creamy.

What kind of cheese is best for frittata? ›

Some good options include cheddar, gruyere, feta, and goat cheese. Add flavorings: Enhance the flavor of your frittata by adding herbs like thyme, rosemary, or basil, or spices like paprika, cumin, or chili powder. Pre-cook vegetables: Cook any vegetables you plan to add to the frittata before adding them t.

How do I know when my frittata is done? ›

Cook the frittata in the oven just until the centre is no longer wobbly and the edges are golden-brown. If still unsure, place a knife into the centre of the frittata. If raw eggs run out, keep cooking. You want the eggs to be just set as the frittata will keep cooking while it's standing.

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

This also holds true for aromatics, like onions, and sturdy veggies, like raw potatoes. "They won't get much more tender once you add the beaten eggs," says Perry, "So cook them fully before combining everything." Don't be afraid of getting a little color on the vegetables: That's what makes them so delicious!

When building a frittata What is a good ratio of filling to eggs? ›

The answer is a ratio. For every six eggs, use 1/4 cup heavy cream, 1 cup cheese, and 2 cups total of vegetables and/or meat. This will get you a frittata with a hearty filling — especially if you're using something like potatoes and bacon — and a creamy egg custard shot through with the tang of cheese.

What goes well with frittata? ›

Frittata Serving Suggestions

If you're serving your frittata as part of a bigger brunch, mimosas, classic french toast, banana bread, pancakes or muffins, French toast, baked oatmeal, overnight oats, blueberry scones, or fruit salad would all be great choices to go with it.

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 do you thicken a frittata? ›

When cooking a frittata, it's always a good idea to add dairy, specifically whole milk. Dairy isn't absolutely required to make a frittata, but if you want an ideal creamy consistency, you should add it. If milk isn't your style, you can even add yogurt to your frittata recipe to thicken it.

What part of the egg is gluten-free? ›

Eggs are naturally gluten-free. Any gluten present in a hen's diet is completely broken down during the hen's digestive process, meaning there is no gluten that makes it way to the egg.

Why are eggs not gluten-free? ›

Yes, eggs are naturally gluten-free.

However, eggs are often at a high risk for cross-contact due to the ways they are prepared.

What brand of eggs are gluten-free? ›

Are All Eggs Gluten Free? Real eggs, no matter their grade, size or color, are naturally gluten free. Whether the egg comes from a chicken, duck, or another bird doesn't make a difference.

How is the fluffiness of a puffy omelet achieved? ›

How to Make a Fluffy Omelet. Whisk egg yolks, melted butter, and salt together in bowl. Place egg whites in bowl of stand mixer and sprinkle cream of tartar over surface. Fit stand mixer with whisk and whip egg whites on medium-low speed until foamy.

What part of the egg makes things fluffy? ›

The main way to make cakes fluffy is to incorporate air. This can be done by beating the egg whites separately from the yolks and incorporating them carefully into the batter. Like that, you retain the air bubbles created while beating the egg whites and your cake is fluffier.

Why is my omelette fluffy? ›

This is the key to making fluffy omelettes, just whisk the egg yolk and egg white separately. This helps in giving that perfect restaurant-like texture to the homemade omelettes. Also make sure you whisk the egg portions in a way that they turn frothy, this will add on the fluffiness of the omelettes.
