What Exactly is a Frittata?

Before we dive into the recipe, let’s clarify what a frittata is. Often confused with an omelet or a quiche, a frittata is an Italian egg-based dish similar to an omelet or crustless quiche, enriched with various ingredients like meats, cheeses, and vegetables. Unlike an omelet, which is usually cooked quickly and folded, a frittata is cooked slowly over a low heat on the stovetop and often finished under a broiler or baked in the oven until set. This slow cooking creates a denser, more cohesive texture, making it perfect for slicing and serving as a casserole. Its open-faced nature allows for beautiful presentation of the fillings, making it a feast for both the eyes and the palate.

Ingredients for Your Perfect Frittata

Crafting a memorable frittata begins with quality ingredients. Here’s what you’ll need for this irresistible spinach and goat cheese version, along with some insights and substitution tips:

• Eggs: The star of the show! Use large, fresh eggs for the best texture and flavor. They bind all the delicious ingredients together, creating that signature fluffy base. For a richer frittata, ensure your eggs are at room temperature before whisking.
• Fresh Spinach: Packed with nutrients, spinach adds a subtle earthy flavor and vibrant color. Make sure to thoroughly wash and roughly chop your fresh spinach. If using frozen spinach, thaw it completely and squeeze out all excess water to prevent a watery frittata.
• Cherry Tomatoes: These small, sweet gems are essential. Halved, they release their juicy sweetness during baking, creating delightful little bursts of flavor. You can use grape tomatoes as well, or even diced Roma tomatoes if cherry tomatoes aren’t available, though the “pop” factor might be slightly less prominent.
• Goat Cheese: This is where much of the frittata’s character comes from. Goat cheese offers a unique tangy, creamy, and slightly salty flavor that pairs exceptionally well with spinach and tomatoes. Its soft texture melts beautifully into the eggs, enhancing the overall creaminess. If you’re experimenting, feta cheese provides a similar saltiness and crumbly texture, while cream cheese can offer an even milder, richer creaminess.
• Heavy Cream: The secret to a truly rich and creamy frittata. Heavy cream adds a luxurious texture and mouthfeel that elevates the dish from good to extraordinary. If you prefer a lighter option, whole milk or half-and-half can be used, but the final texture will be less decadent. For a dairy-free alternative, unsweetened full-fat coconut milk or cashew cream can work, though they may impart a subtle flavor.
• Salt: Essential for seasoning the eggs and bringing out the flavors of all the ingredients. Kosher salt is recommended for its pure taste and easy dissolution, but sea salt works just as well. Always season to taste, remembering that goat cheese also contributes a degree of saltiness.
• Butter: Used for greasing the baking dish, butter helps prevent sticking and adds a subtle richness to the crust of the frittata. You can also use olive oil or a non-stick cooking spray for a similar effect.

How to Make Your Spinach and Goat Cheese Frittata Casserole

Preparing this delightful frittata is incredibly simple and takes minimal effort for maximum flavor. Follow these straightforward steps:

1. Prepare Your Baking Dish: Begin by preheating your oven to 350 degrees F (175 degrees C). While the oven heats, thoroughly butter a 9×13-inch baking dish. Buttering ensures a beautiful, golden crust and prevents the frittata from sticking, making for easy serving.
2. Whisk the Egg Mixture: In a large mixing bowl, crack the eggs and whisk them vigorously until the yolks and whites are fully combined and slightly frothy. This incorporates air, which contributes to a fluffy frittata. Stir in the heavy cream, salt, and about 1/4 cup of the goat cheese. Add the fresh spinach, ensuring it’s evenly distributed throughout the mixture.
3. Assemble and Bake: Pour the egg mixture into your prepared buttered baking dish. Evenly scatter the remaining goat cheese and the halved cherry tomatoes over the top. The tomatoes will sink slightly, creating pockets of juicy sweetness.
4. Bake to Perfection: Place the baking dish in the preheated oven and bake for 22-25 minutes. The frittata is fully cooked when the edges are set and lightly golden, and the center is firm to the touch. A toothpick inserted into the center should come out clean. Avoid overbaking, as this can lead to a dry frittata.

Allow the frittata to rest for a few minutes before slicing and serving. This helps it set further and makes for cleaner cuts. Enjoy!

Frequently Asked Questions About Frittatas

Can I add other vegetables to my frittata?

Absolutely, and we strongly encourage it! Frittatas are wonderfully forgiving and are an excellent way to use up any vegetables that might be nearing their expiration date in your fridge. Think colorful bell peppers (sautéed first for tenderness), finely diced onions or shallots, mushrooms (sautéed to remove moisture), zucchini, or even roasted asparagus tips. For heartier vegetables like potatoes or sweet potatoes, it’s best to pre-cook them slightly before adding them to the egg mixture to ensure they are tender. Fresh herbs like basil, chives, or parsley also make fantastic additions, adding a burst of fresh flavor.

Can I make this in a cast-iron skillet instead?

Yes, you certainly can, and it’s a fantastic method for achieving a slightly crispier bottom crust! To adapt this recipe for a cast-iron skillet, begin by buttering your skillet generously. Pour the egg mixture into the buttered cast-iron skillet and cook it on the stovetop over medium-high heat for about 1 minute, just until the edges begin to set. Then, carefully transfer the skillet to a preheated oven at 425 degrees F (220 degrees C). Bake for an additional 10-14 minutes, or until the frittata is puffed and golden brown, and the center is set. This method gives you the best of both worlds: a crispy base and a perfectly cooked, fluffy top.

What does a frittata taste like?

This spinach and goat cheese frittata, in particular, tastes like pure heaven! It’s an incredibly creamy, rich, and wonderfully fluffy dish that manages to be both comforting and elegant. The eggs provide a delicate, tender base, while the heavy cream adds an undeniable richness. The goat cheese melts into creamy pockets, imparting a delightful tang that cuts through the richness, and the spinach adds a subtle earthiness. The cherry tomatoes are the perfect sweet counterpoint, bursting with juice in every bite. Hands down, this is one of my favorite dishes to prepare for breakfast, especially when hosting a large crowd during the holidays or for a special weekend brunch. It’s truly a gourmet experience made simple.

Can I make this frittata ahead of time? How do I store and reheat it?

Yes, this frittata casserole is an excellent make-ahead option, perfect for meal prepping! Once baked, let the frittata cool completely at room temperature. Then, cover the baking dish tightly with plastic wrap or aluminum foil, or transfer individual slices to airtight containers. Store it in the refrigerator for up to 3-4 days. To reheat, you can warm individual slices in the microwave for 1-2 minutes until heated through, or place the entire casserole (covered with foil) in a preheated oven at 300°F (150°C) for 15-20 minutes, or until warmed through. It’s also delicious served cold or at room temperature, making it ideal for picnics or packed lunches.

Can I freeze this frittata?

Yes, you can freeze frittata slices for longer storage! Once the frittata has completely cooled, slice it into individual portions. Wrap each slice tightly in plastic wrap, then again in aluminum foil, or place them in freezer-safe airtight containers. Freeze for up to 2-3 months. To reheat from frozen, remove the wrapping and bake in a preheated oven at 350°F (175°C) for about 20-30 minutes, or until thoroughly heated. Alternatively, you can thaw slices overnight in the refrigerator and then reheat as described above.

Tips for a Perfectly Fluffy Frittata Every Time:

• Don’t Overmix the Eggs: Whisking until just combined and slightly frothy is enough. Overmixing can incorporate too much air, leading to a frittata that deflates.
• Don’t Overcook: Overcooked eggs become rubbery. Keep an eye on it towards the end of the baking time. The center should be set but still slightly moist.
• Room Temperature Ingredients: Eggs and cream at room temperature mix more evenly and cook more consistently.
• Grease Your Dish Well: This prevents sticking and ensures easy removal and a nice presentation.
• Rest Before Serving: Letting the frittata rest for 5-10 minutes after baking allows it to set completely, making it easier to slice and serve.
