Cooking Instructions

Preparing the Vegetables

The first step to a delicious frittata is to get your vegetables ready. We start by dicing a yellow onion. I find yellow onions lend a lovely sweetness without being overpowering, but a sweet onion would also be a great choice here. Next, we’ll chop up our baby spinach. You don’t need to be too precise with the chopping; a rough chop is perfectly fine. Slice your cherry tomatoes in half. This helps them release their juices as they cook, adding moisture and flavor to the frittata. Finally, slice your mushrooms. I like to use cremini or white button mushrooms for this frittata, but feel free to experiment with your favorites like shiitake or oyster mushrooms for a deeper, more complex flavor. Having all your ingredients prepped and ready to go is key to a smooth cooking process, especially with a frittata where things move relatively quickly once the eggs are added.

Sautéing the Aromatics and Mushrooms

Now it’s time to build some flavor. Grab an oven-safe skillet, about 10-12 inches in diameter, and heat a tablespoon of olive oil or butter over medium heat. Add the diced yellow onion to the skillet and cook, stirring occasionally, until it becomes softened and translucent. This usually takes about 5-7 minutes. We’re not looking for browning here, just a gentle softening to release its sweetness. Once the onions are ready, add the sliced mushrooms to the skillet. Cook the mushrooms until they release their moisture and start to brown slightly, which will take another 5-8 minutes. Browning the mushrooms is crucial for developing their rich, earthy flavor; it’s where all that delicious umami comes from. Don’t overcrowd the pan, as this will steam them instead of browning them. If your skillet seems too full, you can cook the mushrooms in batches.

Incorporating the Tomatoes and Spinach

With the onions and mushrooms nicely softened, it’s time to add the cherry tomatoes and spinach. Stir in the halved cherry tomatoes and cook for about 2-3 minutes, just until they start to soften slightly and their skins begin extract to wrinkle. This will release some of their sweet, acidic juices into the pan. Next, add the chopped baby spinach. It will seem like a lot of spinach, but it wilts down considerably. Stir it into the onion, mushroom, and tomato mixture until it’s just wilted, which should only take about a minute or two. Season this mixture with a pinch of salt and pepper to start building the overall flavor profile of the frittata. This sautéed vegetable base is what gives the frittata its wonderful texture and depth of flavor.

Creating the Egg Mixture and Assembling the Frittata

While the vegetables are finishing up in the skillet, let’s prepare our egg custard. In a medium bowl, crack the 8 large eggs. Add the heavy cream (or your chosen dairy alternative like Greek yogurt or sour cream for a slightly different tang and richness). Whisk everything together until it’s well combined and slightly frothy. Next, we’ll add our seasonings: the ground mustard, garlic powder, ½ teaspoon of salt, and ¼ teaspoon of ground black pepper. The ground mustard might seem unusual in a frittata, but it adds a subtle depth and helps to emulsify the eggs, creating a creamier texture. Whisk these ingredients in thoroughly. Once the vegetables are in the skillet and slightly cooled, gently pour the egg mixture evenly over the vegetables. Ensure the vegetables are distributed relatively evenly in the pan so you get a good mix in every slice. Sprinkle the shredded mozzarella cheese evenly over the top of the egg mixture. The cheese will melt beautifully and create those irresistible cheesy pockets throughout the frittata.

Finishing the Frittata in the Oven

Now for the magic! We need to finish cooking the frittata so the eggs set and the top becomes golden and delicious. Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Carefully transfer the oven-safe skillet with the assembled frittata into the preheated oven. Bake for approximately 15-20 minutes, or until the edges are set and slightly puffed, and the center is just set. You can check for doneness by gently jiggling the pan; the center should no longer be liquid. If the top seems to be browning too quickly before the center is set, you can loosely tent it with aluminum foil. Once it’s done, carefully remove the skillet from the oven. Let the frittata rest in the skillet for about 5-10 minutes before slicing. This resting period is important as it allows the frittata to fully set and makes it much easier to slice without it falling apart. Serve warm or at room temperature. It’s delicious on its own, or with a side salad and some crusty bread.

Frequently Asked Questions:

Can I use different types of mushrooms?

Absolutely! While cremini mushrooms are a fantastic all-rounder, feel free to experiment with shiitake for a deeper, umami flavor, oyster mushrooms for a delicate texture, or even a mix of your favorites. Just ensure they’re cleaned and sautéed properly before adding them to the frittata mixture.

How can I make this frittata dairy-free?

You can easily make this Mushroom Frittata dairy-free by substituting the milk with unsweetened plant-based milk (like almond or soy) and using nutritional yeast instead of cheese for a cheesy flavor. For a creamy texture, a tablespoon or two of cashew cream can also work wonders.

What’s the best way to store leftovers?

Leftover frittata can be stored in an airtight container in the refrigerator for up to 3-4 days. It reheats beautifully in a low oven or a non-stick skillet. It’s also delicious served cold as part of a salad or sandwich!
